If LU has to be rejected because DGSM mechanism cannot reach the needed HLR, then returning reject cause #17 (Network Failure) is the most accurate and truthful description of what is actually happening. Reject cause #2 (IMSI unknown in HLR) is unlikely to be a good choice: in areas where regular commercial cell services are present alongside with experimental/adventurous Osmocom-based GSM networks, this reject cause is acutely dangerous as described in the previous commit, and even in areas where no regular commercial cell services are present (the presumed intended use case for DGSM), the behavior of commanding LU-failing phones "please don't ever again try to connect to ANY network until the user power-cycles you" is unlikely to be correct/desirable. If that behavior _is_ desired, it should be configured explicitly, not by default. Change-Id: I557ae1d3291066a87228b5db4f2e207ea721329c
osmo-hlr - Osmocom HLR Implementation
This repository contains a C-language implementation of a GSM Home Location Register (HLR). It is part of the Osmocom Open Source Mobile Communications project.
Warning: While the HLR logical functionality is implemented, OsmoHLR does not use the ETSI/3GPP TCAP/MAP protocol stack. Instead, a much simpler custom protocol (GSUP) is used. This means, OsmoHLR is of no use outside the context of an Osmocom core network. You can use it with OsmoMSC, OsmoSGSN etc. - but not directly with third party components.
