Problems solved by technology

Since NPDB and STP are tightly coupled, NPDB is not an independent network element, which has the following defects: 1) STP is the core equipment of the signaling network, which brings the risk of upgrading and transforming the signaling network and increases t

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...

Abstract

Disclosed is a mobile network number portability service method; the system is composed of an independent number portability database SRF-DPDB with SRF function for accessing the signaling system 7, and a local service management system LSMS. In a relative mobile switch center, the overall code translation point office data is set to point to SRF-NPDB, the SRF-NPDB is used for changing and converting numbers of number portability users to realize the purposes of addressing and continuous control, the LSMS is used for managing the number mapping relation of local portability users and synchronizing the number mapping relation to the SRF-NPDB. The invention is characterized in that an independent network element equipment is adopted for setting only through switch node data without changing a signaling transition point STP in prior art, the number portability service can be implemented fairly and independently and is avoided from coupling tightly with the STP so that the communication service quality is guaranteed and an effective method for implementing independent mobile network number portability service is disclosed.

Description

technical field [0001] The invention relates to a method for implementing number portability services in a mobile communication network. Specifically, on the premise of not upgrading the existing communication network equipment, an independent number portability database NPDB is introduced to make office data only for relevant mobile switching nodes. Setting, the signaling relay function SRF and the number portability service can be realized conveniently. Background technique [0002] "Number Portability" (Number Portability) service, called NP service, can enable users to continue to use the original communication number without changing the number when the address is moved, the service provider is changed, or the service is changed. The business that countries implement first. [0003] The original number (ISDN number) of the user X (subscriber) who has the number portability service is the user number A allocated by the network operator A. When the user changes operator...
