23.0123GPPLocation management proceduresRelease 17TS
The text in this clause is a supplement to the definition in the SDL diagrams; it does not duplicate the information in the SDL diagrams.
This specification shows the location management application processes interworking with the MAP protocol handler, which is specified in 3GPP TS 29.002 . The MAP protocol defines supervision timers. If a supervision timer expires before a distant entity responds to a signal, the handling is as defined in 3GPP TS 29.002 . In general, the protocol handler reports timer expiry to the application as an error condition or negative response. Where a timer is shown in this specification, therefore, it is an application timer rather than a protocol timer. Interworking with the protocol handlers uses functional signal names which do not necessarily have a one-to-one correspondence with the names of messages used in the MAP protocols.
