24、 880 State Transition Tables for Mobile Network Location Protocol (MNLP)1 IntroductionThis Part provides the state transition tables for the Mobile Network Location Protocol (MNLP) specified in Part 501.MNLP is an asymmetrical protocol, which means that the behavior and procedures for the Mobile Hom

25、e Function differ from the behavior and procedures used by the Mobile Serving Function. Two state transition tables are provided: one for the Mobile Home Function and another for the Mobile Serving Function.In the event of any conflict, either real or perceived, between this Part and Part 501, that

26、conflict shall be resolved in favor of Part 501.1.1 EventsEvents (within the context of these state transition tables as well as for the purpose of Conformance testing) are defined as follows:Types of indicators that may be received:a. Internal eventsb. PDU receipt.The actions to be taken when an ev

27、ent occurs while in a specific state comprise:a.

30、possible by the definition of MNLP No action, no state changeStart Timer To start a timer implies that the timer is set to run for a predefined length of time unless it is stopped. The state matrices do not distinguish between starting an inactive or restarting a currently active timer.Stop Timer To

31、 stop a timer implies that it no longer runs and that the value of the timer at the time it is reset is of no significance. To stop or to reset a timer has the same effect.

34、Mobile Network Location Protocol (MNLP) and the Mobile Network Registration Protocol (MNRP). Therefore the state machines for the Mobile Serving Function (MSF) and the network side state matrix for MNRP are necessarily closely linked.
