Embodiment Construction
[0019] Take MSC's addressing of calling number portability users as an example to illustrate the decoding process of number portability services, as follows: figure 1 Shown:
[0020] (1) MSC sends an addressing SRI message, the global code decoding point is SRF-NPDB, not the original STP connection, (2) STP transfers the message to SRF-NPDB, at this time, the STP that the message passes does not need Participate in number portability service processing, only as a common STP function.
[0021] For messages that do not involve number portability, SRF-NPDB changes the global code decoding node of the signaling message to the decoding node STP set by the original network; for NP business messages, after SRF-NPDB completes the number decoding, it In different cases of moving in and out, it is determined whether the message reply is sent to the requesting node MSC or HLR, (3) the message is returned to the STP, and the STP completes the message transfer function; (4) the addressing...
