System and method for realizing number carryover service between mobile networks

Abstract

A system for realizing the number carrying service between mobile networks and a method are provided, wherein the system is formed by an independent number carrying database SRF-NPDB and a local service management system LSMS, which have the SPF function, and both are accessed into a number seven signaling network. A global office number translation point office data pointing SRF-NPDB is arranged in a related mobile exchange center, and the SRF-NPDB changes and transforms the number of a number carrying user for realizing the purposes of addressing and continuous controlling, and the LSMS is used to manage the number mapping relation of a local portable user, and synchronizes with the SRF-NPDB. The invention has the characteristics that the number carrying service can be fairly and independently carried out through adopting an independent network element device by the data setting of exchange nodes without transforming the current signaling transfer point STP, which avoids the tight coincidence with the STP, guarantees the communication service quality, and provides an effective method for independently opening the number carrying service between the mobile networks.

Description

technical field [0001] The invention relates to a system and 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, and only relevant mobile switching nodes are implemented. By setting the office data, the signaling relay function SRF and number portability services 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 t...

AI Technical Summary

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 the difficulty of implementing number portability; 2) ) It is difficult to access the same local NPDB system for the network of multiple operators; 3) It does not conform to the current network development trend of separation of user data processing and control
