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

[0022] When the present invention realizes the MNP service of mobile inter-network number portability, as shown in FIG. 2 , in one area, 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).

[0023] 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:

[0024] The number portability processing device SRF-NPDB can adopt the "identification of signaling data at the No. Processing m...

Abstract

The invention relates to a mobile communication number portable system and a method based on the signal relay technique, wherein the system comprises a number portable database SRF-NPDB with the signal delay function and a local business management device LSMS which are connected in a relative No.7 signaling chain circuit in series. The SRF-NPDB works in a non-signal point coding mode, when signal information flows through the SRF-NPDB, the coding is carried out to the number of number portable users to realize the aims of searching addresses and controlling spicing, and the LSMS manages the mapping relation of the number of the local portable users, which is synchronizing with the SRF-NPDB. The obvious characteristics of the invention are that an existing signal network and a mobile switched node do not need to be remodeled, and the business load of the existing network is not increased, the number portable business can be equally and separately carried out, which prevents risks in the upgrading and the remodeling of the existing network, guarantees the communication service quality, and provides an effective method for separately developing the mobile internet number portable business.

Description

technical field [0001] The invention relates to a system and method for realizing number portability services in a mobile communication network. Specifically, an independent number portability database NPDB is connected in series in a relevant signaling link, so that the number of the signaling relay function SRF can be realized conveniently. Carry the business system without changing the 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 ...
