Problems solved by technology

[0021] There is a problem in the MNP service in the prior art field: must provide the NPDB server corresponding to the number of the service network in each service network that cooperates with the current service network to provide the MNP service
However, it still has problems in system performance since all the mobile subscribers whose location information inquiry it fails perform mobile number portability inquiry within NPDB, and the called subscriber is judged as "INVALID SUBSCRIBER"

Embodiment Construction

[0044] refer to Figure 5 , the MNP service according to a preferred embodiment of the present invention passes through the original network 110 used to initiate the call, the previous service network 120 that terminates the call when the mobile user changes its mobile service provider, and the current service network 130 that the mobile user has just signed up for to execute.

[0045] The MNP service system in the previous service network 120 includes components used to provide MNP services: GMSC 121 for executing inter-service network call procedures and HLR 123 for storing mobile number portability information including the location or general information of mobile subscribers. The MNP service system in the previous service network 120 is merged with the GMSC 131 in the current service network 130 that performs inter-service network call processing. The NPDB 132 stores information of mobile subscribers who have changed their mobile service providers.

Abstract

The present invention relates to a method and system for mobile number portability service in an asynchronous mobile communication network. More particularly, the present invention has advantages in that system performance is improved and the number of NPDB, which should be provided as many as the number of service networks in the related art, can be reduced into one NPDB, by storing whether mobile subscriber changes his mobile service provider and an address of an NPDB in a service network presently providing the mobile subscriber with mobile service and by performing mobile number portability inquiry only for a mobile subscriber who practically changed his mobile service provider, in the NPDB in the service network presently providing the mobile subscriber with mobile service.

Description

technical field [0001] The present invention mainly relates to the method and the system aiming at the Mobile Number Portability (MNP) in the asynchronous mobile communication network, particularly, relates to its performance can represent whether mobile subscriber has changed its mobile service provider by storing the information Number Portability Database (NPDB) in the service network with which the mobile subscriber is subscribed and method and method improved by using the address to perform a mobile number portability lookup within the NPDB only for mobile subscribers who have changed their mobile service provider system. Background technique [0002] The Mobile Number Portability (MNP) service enables mobile subscribers to change their mobile service provider without changing their mobile number ("mobile number"). This service is described in the Third Generation Partnership Project (3GPP) Technical Specification (TS) 23.066 "Supporting MNP Technology Implementation P...
