[bsc_msc_ip] Fix the re-queuing of packets...

* The MSC is sending us the next 04.08 packet before we have
  received the answer for the cipher model complete. The code was
  supposed to copy all packets from the current queue, to a new
  queue and then send the packets again.
* This would (re)establish the different SAPIs. Now the requeuing
  code was grabbing the packet from the empty queue (NULL pointer)
  and we were dereferencing it. It appears that we need to use
  "head" until the queue is empty.

-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU AGPL, see
-<http://www.gnu.org/licenses/>.

-About OsmoMGW
-=============
-
-OsmoMGW originated from the OpenBSC project, which started as a minimalistic
-all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
-maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
-IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
-approach to fully independent separate programs as in typical GSM networks.
-
-OsmoMGW was one of the parts split off from the old openbsc.git. It originated
-as a solution to merely navigate RTP streams through a NAT, but has since
-matured to a Media Gateway implementation that is capable of streaming RTP for
-2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time
-of writing) transcoding between TRAU, various RTP payloads and IuUP.
-
-The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and
-OsmoBSC, and receives and sends RTP streams as configured via MGCP.
-
-The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found
-in osmo-msc.git) to instruct OsmoMGW via its MGCP service.

-== Configuring OsmoMGW
-
-A basic configation of OsmoMGW mainly consists of specifying the IP address
-and port on which to listen to MGCP commands, but changing the port range at
-which the RTP streams terminate as well as limiting operation to a single call
-agent can be done as well as changing the number of endpoints.
-
-=== Configuring MGCP
-
-By default OsmoMGW listens for MGCP on port 2427 on any IP address. If a call
-agent address is configured then OsmoMGW will only answer MGCP commands from
-that IP port 2727, otherwise all sources are handled. A domain can be
-specified
-
-.Example: MGCP configuration
-----
-OsmoMGW(config-mgcp)# bind ip 127.0.0.1
-OsmoMGW(config-mgcp)# bind port 2427
-OsmoMGW(config-mgcp)# call-agent ip 127.0.0.1
-OsmoMGW(config-mgcp)# domain mgw-bsc
-OsmoMGW(config-mgcp)# local ip 127.0.0.1
-----
-
-=== Configuring the trunk
-
-The first trunk is considered a virtual trunk in OsmoMGW. All
-endpoints of type "rtpbridge" are routed here. The virtual trunk is configured
-in the config-mgcp context.
-
-All other trunks are configured in the config-mgcp-trunk context, but the
-commands used are identical. Right now trunks are considered only for "ds/e1"
-type endpoints.
-
-.Example: MGCP trunk configuration
-----
-OsmoMGW(config-mgcp)# number endpoints 63 <1>
-OsmoMGW(config-mgcp)# rtp bind-ip 10.0.0.1 <2>
-OsmoMGW(config-mgcp)# rtp port-range 12000-14000 <3>
-----
-<1> Maximum number of endpoints that can be allocated at once
-<2> Use this IP when binding RTP endpoints
-<3> Use ports in this range when binding RTP endpoints
-
-There are some options to tweak how RTP forwarding behaves in OsmoMGW:
-
-.Example: MGCP trunk rtp options
-----
-OsmoMGW(config-mgcp)# rtp keep-alive 30 <1>
-OsmoMGW(config-mgcp)# rtp-patch ssrc <2>
-OsmoMGW(config-mgcp)# rtp-patch timestamp <3>
-----
-<1> Send dummy UDP packets periodically to RTP destination
-<2> Hide SSRC changes
-<3> Ensure RTP timestamp is aligned with frame duration
-
-NOTE: Changes to trunks that affect resource allocation, such as newly created
-trunks or a change of the number of available endpoints, require a full restart
-of osmo-mgw!
-
-=== E1 trunk considerations
-
-While the RTP bridge trunks are natively based on IP no special considerations
-are required during setup. E1 trunks are mapped on a physical E1 line, which has
-to be configured as shown below.
-
-.Example: E1 line setup
-----
-OsmoMGW(config-e1_input)# e1_line 0 driver dahdi <1>
-OsmoMGW(config-e1_input)# e1_line 0 port 2 <2>
-----
-<1> Name of the libosmo-abis driver implementation ("dahdi")
-<2> Port number of the physical E1 port to use (2)
-
-In osmo-mgw the e1_input node is used to configure the physical E1 line. The
-line number will be used internally to identify the configured E1 line. The
-port number is the physical E1 connector (sometimes called 'span') at the E1
-hardware. Per trunk an individual E1 line will be needed. Beware that the E1
-driver may also need configuration settings that are not discussed here.
-
-.Example: E1 trunk setup
-----
-OsmoMGW(config-mgcp)# trunk 0 <1>
-OsmoMGW(config-mgcp-trunk)# line 0 <2>
-----
-<1> Creation of a trunk (0)
-<2> Reference to the E1 line to use (0)
-
-The E1 trunk is created along with a number, typically starting at 0, but if
-required any number from 0-64 is allowed. The E1 trunk configuration concerning
-the IP related aspects is nearly identical to the configuration of the virtual
-trunk. However, it is important that the user assigns one of the E1 line numbers
-that were configured under the e1_input node.
-
-NOTE: The endpoint name that is used on MGCP level will include the trunk number,
-not the E1 line number. For simplicity (and compatibility with OsmoBSC) it is
-recommended to use equal numbers for trunk and E1 line. However, if required any
-E1 line can be mapped flexible on any trunk as long as the mapping is bijective.
-
-.Example: A typical configuration with one E1 trunk
-----
-e1_input
- e1_line 0 driver dahdi
- e1_line 0 port 2
-mgcp

-== MGCP Endpoints
-
-MGCP organizes the switching resources in so called endpoints. Each endpoint is
-referenced by its unique identifier. While RFC 3435 specifies a naming scheme, the
-actual identifier naming is subject to the implementation and configuration.
-
-=== RTP proxy / RTP bridge endpoints
-
-OsmoMGW implements a freely configurable number of `rtpbridge` endpoints. Those
-endpoints are able to host two connections at a time to model the functionality
-of a tandem switch.
-
-RTP bridge endpoint identifiers are referenced by the string `rtpbridge/`, a
-hexadecimal number without leading zeros and a domain name (configurable).
-
-----
-rtpbridge/<number>@<domain>
-----
-
-.Example: List of virtual endpoints
-----
-rtpbridge/1@mgw

-rtpbridge/10@mgw
-----
-
-=== E1/T1 endpoints
-
-OsmoMGW supports E1 subslot multiplexing as specified by I.460. All possible
-subslot combinations are mapped on individual endpoints. The endpoint names
-are prefixed with `ds/e1-` followed by the trunk number and the E1 timeslot.
-The subslot is defined by a bit rate and a bit offset.
-
-----
-ds/e1-<trunk>/s-<timeslot>/su<bitrate>-<bitoffset>@<domain>

-----
-
-When creating connections on endpoints that reside in one E1 timeslot the call
-agent must make sure that no overlapping endpoints are used. It is for example
-not possible to use `ds/e1-0/s-2/su16-2@mgw` and `ds/e1-0/s-2/su8-3@mgw` at the
-same time because they overlap.

-== MGCP Extensions
-
-The MGCP protocol is extendable. The following non-standard extensions are
-understood by OsmoMGW.
-
-=== `X-Osmo-IGN`
-
-`X-Osmo-IGN` indicates to OsmoMGW that specific items of an endpoint should be
-ignored, so that it is lenient on mismatching values that would normally
-indicate collisions or configuration errors.
-
-==== `X-Osmo-IGN` Format
-
-The value part of `X-Osmo-IGN` must be one or more items separated by one or more
-spaces. Each item consists of one or more non-whitespace characters.
-
-.Example: `X-Osmo-IGN` format with three ficticious items "X", "abc" and "123".
-----
-X-Osmo-IGN: X abc 123
-----
-
-`X-Osmo-IGN` must be issued in the MGCP header section (typically as its last item),
-before the SDP section starts.
-
-==== Supported `X-Osmo-IGN` Items
-
-Currently, the following `X-Osmo-IGN` items are supported:
-
-* `C`: ignore CallID mismatches, i.e. differing "C" values between connections
-  on the same endpoint.
-
-.Note:
-`X-Osmo-IGN` does not support ignoring mismatches on the domain part of
-an endpoint name, e.g. ignoring a mismatch on "example.com" in
-`rtpbridge/123abc@example.com`. Instead, you may globally configure OsmoMGW
-with `mgcp` / `domain *` to permit all domain parts.
-
-===== `X-Osmo-IGN: C`
-
-By default, OsmoMGW verifies that all CallIDs ("C" values) match for all
-connections on any one given endpoint. To ignore CallID mismatches, pass a `C`
-in the `X-Osmo-IGN` header, for the first or the second `CRCX` on an endpoint.
-When the `X-Osmo-IGN: C` is sent for any one `CRCX` on an endpoint, CallID
-mismatches will be ignored for that and all subsequent messages for that
-endpoint. Hence this header only needs to be included once per endpoint, in any
-`CRCX` message that precedes or coincides with a CallID mismatch.
-
-This is particularly useful for a BSC that is connected to an A/SCCPlite MSC,
-where the BSC and MSC each are expected to configure their respective own
-connection on a shared endpoint. For A/SCCPlite, it is impossible for the BSC
-to know the CallID that the MSC will use, so CallID mismatches are inevitable.
-See also OsmoBSC, which will by default pass the `X-Osmo-IGN: C` header for
-endpoints associated with an A/SCCPlite MSC.
-
-.Example: `CRCX` message that instructs OsmoMGW to ignore CallID mismatches

-
-[[intro_overview]]
-=== About OsmoMGW
-
-OsmoMGW is the Osmocom implementation of a media gateway to handle user
-plane (voice) traffic in cellular networks. It can connect and optionally
-transcode RTP voice streams between different network elements such as BTSs
-and external entities like SIP. It is typically co-located with both OsmoBSC
-and OsmoMSC and controlled by them via MGCP, the Media Gateway Control
-Protocol.

-=== Software Components
-
-OsmoMGW contains a variety of different software components, which we’ll
-quickly describe in this section.
-
-==== MGCP Implementation
-
-OsmoMGW brings its own MGCP implementation through which OsmoMGW is
-controlled.
-
-The commands implemented are CRCX, MDCX, DLCX and RSIP. The command AUEP is
-implemented as a stub and will simply respond with OK.
-
-==== RTP implementation
-
-Support for IuUP which is used in 3G cells is quite lacking at the moment.
-3G<->3G and 2G<->2G calls should work, but 3G<->2G does not.
-
-==== Audio transcoder
-
-Transcoding is currently not supported in OsmoMGW.
-
-=== Limitations
-
-At the moment (November 2020), OsmoMGW implements RTP proxy / RTP bridge
-type endpoints and E1/T1 16k/8k sub-slots with TRAU frames for classic BTS
-support. To the RTP proxy / RTP bridge endpoints two RTP connections can
-be established, which then work as a tandem. E1/T1 endpoints support one
-RTP connection at a time that is associated with a sub-slot on an E1 line.
-We are planning to add further endpoint types for:
-
-- classic E1/T1 timeslots (64kBps alaw/ulaw)
-- announcement/playout end-points
-- conference endpoints
-
-=== Additional resources

-<1> make sure to specify your specific VLAN interface name here instead of `eth0.9`.
-<2> create a egress QoS map that maps the priority value 1:1 to the PCP. We also include the
-    mapping 5:5 and 7:7 from the osmo-bsc example (see <<userman-osmobsc>>) here.
-
-NOTE:: The settings of the `ip` command are volatile and only active until
-the next reboot (or the network device or VLAN is removed).  Please refer to
-the documentation of your specific Linux distribution in order to find out how
-to make such settings persistent by means of an `ifup` hook whenever the interface
-comes up.  For CentOS/RHEL 8 this can e.g. be achieved by means of an `/sbin/ifup-local
-script` (when using `network-scripts` and not NetworkManager).  For Debian or Ubuntu,
-this typically involves adding `up` lines to `/etc/network/interfaces` or a `/etc/network/if-up.d`
-script.

-# This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/.
-# It may be run two ways:
-# - from a git repository in which the "git describe" command below
-#   produces useful output (thus requiring at least one signed tag)
-# - from a non-git-repo directory containing a .tarball-version file, which
-#   presumes this script is invoked like "./git-version-gen .tarball-version".
-
-# In order to use intra-version strings in your project, you will need two
-# separate generated version string files:
-#
-# .tarball-version - present only in a distribution tarball, and not in
-#   a checked-out repository.  Created with contents that were learned at
-#   the last time autoconf was run, and used by git-version-gen.  Must not
-#   be present in either $(srcdir) or $(builddir) for git-version-gen to
-#   give accurate answers during normal development with a checked out tree,
-#   but must be present in a tarball when there is no version control system.
-#   Therefore, it cannot be used in any dependencies.  GNUmakefile has
-#   hooks to force a reconfigure at distribution time to get the value
-#   correct, without penalizing normal development with extra reconfigures.
-#
-# .version - present in a checked-out repository and in a distribution
-#   tarball.  Usable in dependencies, particularly for files that don't
-#   want to depend on config.h but do want to track version changes.
-#   Delete this file prior to any autoconf run where you want to rebuild
-#   files to pick up a version string change; and leave it stale to
-#   minimize rebuild time after unrelated changes to configure sources.
-#
-# It is probably wise to add these two files to .gitignore, so that you
-# don't accidentally commit either generated file.
-#
-# Use the following line in your configure.ac, so that $(VERSION) will
-# automatically be up-to-date each time configure is run (and note that
-# since configure.ac no longer includes a version string, Makefile rules
-# should not depend on configure.ac for version updates).
-#
-# AC_INIT([GNU project],
-#         m4_esyscmd([build-aux/git-version-gen .tarball-version]),
-#         [bug-project@example])
-#
-# Then use the following lines in your Makefile.am, so that .version
-# will be present for dependencies, and so that .tarball-version will
-# exist in distribution tarballs.
-#
-# BUILT_SOURCES = $(top_srcdir)/.version

+This experimental patch splits one E1 card into three virtual cards,
+
+TS 1,2,3,4,5 is card 0
+TS 6,7,8,9,10 is card 1
+TS 11,12,13,14 is card 2
+
+This allows you to run one L2 TEI handler on each of the virtual cards,
+which is required if you want to run multiple BTS on a single E1 link.
+
+Thanks to Andreas Eversberg for this patch.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+About OpenBSC
+=============
+
+OpenBSC is a minimalistic implementation of the GSM Network, with particular
+emphasis on the functionality typically provided by the BSC, MSC, HLR, VLR.
+
+Its only current interface is a mISDN based E1 interface utilizing the A-bis
+protocol between BSC and BTS.  In other words, you can connect an existing
+GSM Base Transceiver Station (BTS) through E1 to OpenBSC.
+
+So far, it has only been tested with the Siemens microBTS BS-11.  Test reports
+with other BTS are appreciated!
+
+This project is still in its early days, and there are lots of areas where it
+doesn't behave as per GSM spec.

+E1 related data model
+
+This data model describes the physical relationship of the individual
+parts in the network, it is not the logical/protocol side of the GSM
+network.
+
+A BTS is connected to the BSC by some physical link.  It could be an actual
+E1 link, but it could also be abis-over-IP with a mixture of TCP and RTP/UDP.
+
+To further complicate the fact, multiple BTS can share one such pysical
+link.  On a single E1 line, we can easily accomodate up to three BTS with
+two TRX each.
+
+Thus, it is best for OpenBSC to have some kind of abstraction layer.  The BSC's
+view of a BTS connected to it.  We call this 'bts_link'.  A bts_link can be
+* all the TCP and UDP streams of a Abis-over-IP BTS
+* a set of E1 timeslots for OML, RSL and TRAU connections on a E1 link
+* a serial line exclusively used for OML messages (T-Link)
+
+A bts_link can be registered with the OpenBSC core at runtime.

+Ideas about a handover algorithm
+======================================================================
+
+This is mostly based on the results presented in Chapter 8 of "Performance
+Enhancements in a Frequency Hopping GSM Network" by Thomas Toftegaard Nielsen
+and Joeroen Wigard. 
+
+
+=== Reasons for performing handover ===
+
+Section 2.1.1: Handover used in their CAPACITY simulation:
+
+1) Interference Handover
+
+Average RXLEV is satisfactory high, but average RXQUAL too low indicates
+interference to the channel.  Handover should be made.
+
+2) Bad Quality
+
+Averaged RXQUAL is lower than a threshold
+
+3) Low Level / Signal Strength
+
+Average RXLEV is lower than a threshold
+
+4) Distance Handover
+
+MS is too far away from a cell (measured by TA)
+
+5) Power budget / Better Cell
+
+RX Level of neighbor cell is at least "HO Margin dB" dB better than the
+current serving cell.
+
+=== Ideal parameters for HO algorithm ===
+
+Chapter 8, Section 2.2, Table 24:
+
+Window RXLEV averaging:		10 SACCH frames (no weighting)
+Window RXQUAL averaging:	1 SACCH frame (no averaging)
+Level Threashold:		1 of the last 1 AV-RXLEV values < -110dBm
+Quality Threshold:		3 of the last 4 AV-RXQUAL values >= 5
+Interference Threshold:		1 of the last AV-RXLEV > -85 dBm &
+				3 of the last 4 AV-RXQUAL values >= 5
+Power Budget:			Level of neighbor cell > 3 dB better
+Power Budget Interval:		Every 6 SACCH frames (6 seconds ?!?)
+Distance Handover:		Disabled
+Evaluation rule 1:		RXLEV of the candidate cell a tleast -104 dBm
+Evaluation rule 2:		Level of candidate cell > 3dB better own cell
+Timer Successful HO:		5 SACCH frames
+Timer Unsuccessful HO:		1 SACCH frame
+
+In a non-frequency hopping case, RXQUAL threshold can be decreased to
+RXLEV >= 4
+
+When frequency hopping is enabled, the following additional parameters
+should be introduced:
+
+* No intra-cell handover
+* Use a HO Margin of 2dB
+
+=== Handover Channel Reservation ===
+
+In loaded network, each cell should reserve some channels for handovers,
+rather than using all of them for new call establishment.  This reduces the
+need to drop calls due to failing handovers, at the expense of failing new call
+attempts.
+
+=== Dynamic HO Margin ===
+
+The handover margin (hysteresis) should depend on the RXQUAL. Optimal results
+were achieved with the following settings:
+* RXQUAL <= 4: 9 dB
+* RXQUAL == 5: 6 dB
+* RXQUAL >= 6: 1 dB
+
+
+
+== Actual Handover on a protocol level ==
+
+After the BSC has decided a handover shall be done, it has to
+
+# allocate a channel at the new BTS
+# allocate a handover reference
+# activate the channel on the BTS side using RSL CHANNEL ACTIVATION,
+  indicating the HO reference
+# BTS responds with CHAN ACT ACK, including GSM frame number
+# BSC sends 04.08 HO CMD to MS using old BTS
+

+oml interface design notes
+
+problems:
+
+* there is no way how to tag a command sent to the BTS, with the response
+  having the same tag to identify the originator of the command
+* therefore, we can have e.g. both the BSC and the OML interface send a
+  SET ATTRIBUTE message, where the responses would end up at the wrong
+  query.
+
+the only possible solutions i can imagine:
+* have some kind of exclusive locking, where the OML interface gets blocked
+  from the BSC and is exclusively assigned to the OML console until all commands
+  of the OML console have terminated.  This can either be done explicitly
+  dynamically or on demand
+
+* use the OML interface synchronously, i.e. always wait for the response from
+  the BTS before
+
+* unilateral / unsolicited messages need to be broadcasted to both the BSC and
+  the OML console
