trans_lcls_compose(): Set PLMN fron cell currently in use The MS in general provides the Selected PLMN ID (IE) in the Complete Layer 3 Information message. osmo-msc handles that message in msc_a_ran_dec_from_msc_i() and stores the information of the PLMN in msc_a->via_cell. If no PLMN information is provided in the message, then at that same place the PLMN configured in the VTY is taken as an implicit default. This patch changes trans_lcls_compose() to use the PLMN stored in msc_a->via_cell instead of the VTY configured one, meaning the PLMN provided by the MS (through the RAN in use) is used if available (otherwise the VTY-configure one is still used, as before). With this patch the PLMN VTY config option use is relegated to a single point of use in msc_a_ran_dec_from_msc_i() where the Complete Layer 3 Information is used. As a result, it becomes clear now that the VTY config is only applied in the scenario where no PLMN is provided at that time. Related: SYS#6360 Change-Id: Ibad0005a1d7cef64dd8fefa3e554ba99a06c3666

OsmoMSC originated from the OsmoNITB project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OsmoNITB 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.
OsmoMSC was one of the parts split off from the old openbsc.git.
