Problems solved by technology

Because 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 the difficulty of implementing number portability; 2) ) does not conform to the current network development trend of separation of user data processing and control

Embodiment Construction

[0017] When the present invention realizes the mobile inter-network number carrying MNP service, such as figure 2 As shown, in one region, there are multiple mobile operators: operator 1, operator 2, and operator n. Each operator's network is based on a number of signaling points connected to the No. 7 (SS7) signaling network 11 by signaling links, wherein: signaling points include signaling transfer points and voice and data switching nodes, switching Nodes are Mobile Switching Center 12 (MSC), Short Message Center 13 (SMSC), Media Switching Center 14 (MMSC), Gateway Mobile Switching Center 15 (GMSC) and Home Home Register 16 (HLR).

[0018] First, an independent local MNP service system is deployed, including a number portability processing device 21 (SRF-NPDB) with signaling relay function SRF and a local service management device 22 (LSMS). in:

[0019] The number portability processing device SRF-NPDB can adopt the "identification of signaling data at the No. Processi...

Abstract

The invention relates to a mobile telecommunication number portability system based on signaling relay technology, which comprises a number portability database SRF-NPDB which is connected with a relative SS7 link in series and has relay function and a local service management system LSMS. The SRF-NPDB works in an encoding manner free of a signaling-point. When a signaling message passes through the SRF-NPDB, the number decoding of the number portability user is carried out and the aims of addressing and controlling succession are achieved. The LSMS manages the mapping relation of the number of the local portability user number and is synchronous with the SRF-NPDB. The outstanding features are that the reconstruction of the prior signaling network and the mobile switching node is not needed, the service load of the prior network is not increased, the number portability service can be implemented fairly and independently, the reconstruction risk of the prior network is avoided, the communication service quality is ensured, and the invention provides an effective method for independently developing mobile network number portability service.

Description

technical field [0001] The invention relates to a system for implementing number portability services in a mobile communication network. Specifically, an independent number portability database NPDB is connected in series in the relevant signaling link, so that the number portability service of the signaling relay function SRF can be realized conveniently system without the need to modify existing communication network equipment. 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 operators, the user's ISDN number ...
