According to TS29.503, we can choose whether or not to allow LBO roaming
on a per-session basis.
To this end, we have made changes to allow us to set this via the WebUI.
* Add "subscriber_status" cmd to open5gs-dbctl to set values for
"subscriber_status" and "operator_determined_barring" DB fields.
* Add webui View+Edit for those same fields.
* open5gs-hssd now takes those values into account and submits
Operator-Determined-Barring AVP with DB-retrieved value if
subscriber_status is set to OPERATOR_DETERMINED_BARRING.
For more information, see TS 29.272 section 5.2.2.1.3 and 7.3.30.
* Introduce Cancel Location and Insert Subscriber Data features to HSS.
* HSS database will keep track of last known MME and Update Time
* Purged UE flag is established in HSS for future PUR handling
* HSS Thread will connect to database and watch change stream
mongoDB must be configured with a Replica Set to use this
* HSS will send IDR if subscription data changes
* HSS will send CLR to old MME if MME host or realm changes
* Function created to allow ULA and IDR to generate Subscription-Data AVP
* MME Hostname and Realm shown in WebUI
* Resolve freeDiameter errors
During a ULR, if database does not contain a last known MME, a CLR is being sent to a Null destination. This will ensure that a destination is available in the database before sending the CLR.
* Removed change streams. Added PUR handling.
* newline needed at end of file.
* Removed temp variable.
* * Change WebUI to 2x2 display
* Including UE Purged indicator
* Using pointers in ogs_subscription_data_t
* better memory mangement with pointers
* Tweak to Destination used by hss_s6a_send_idr to use last known MME
* Check for null mme_host and mme_realms
Do this before trying to compare the strings.
The network access mode of HSS has been changed to 0 (Packet and Circuit).
Versions of MME prior to v2.4.2 did not use this value. Open5GS set
the attach result of Attach Complete message as it is by looking
at the attach type of the Attach Request message.
Now, if the network access mode of HSS is set to 2 (Only Packet),
this value is affected by MME from v2.4.3. Regardless of the attach type
of the Attach Request, the MME will set EPS Only to the attach result
of Attach Complete.
