Abstract

The method includes steps: (1) SMSC informs second MGW, which is connected to SMSC each other, to create second endpoint; second MGW returns address information of second endpoint back to SMSC; (2) SMSC requests AMSC to take part in this call, and sends address information of second endpoint to AMSC; based on request of SMSC, AMSC switches to the called party, and informs first MGW to create first endpoint, meanwhile sends address information of the second endpoint to first MGW; (3) first MGW establishes coincidence relation between first endpoint and second endpoint, and sends address information of first endpoint to AMSC; through SMSC, AMSC returns address information of the first endpoint to second MGW; MGW establishes coincidence relation between first endpoint and second endpoint. Under IP load supporting mode, the invention can realize concurrent voice service after switching between offices so as to raise use ratio of resources.

Description

technical field

[0001] The invention relates to concurrent services in a wireless communication system, in particular to a method for realizing inter-office concurrent voice services. Background technique

[0002] In the third generation (3G) communication system, the mobile station can also implement the voice service while performing the data service, and this situation is called concurrent service. Specifically, a user using a mobile station may receive a call from another user or call another user for voice communication when performing data services such as data download or web browsing. Similarly, when a user uses a mobile station to access the network and perform voice services, data services can also be sent concurrently. In the concurrent service, the user can first access the data service, and then concurrently issue the voice service; or firstly access the voice service, and then concurrently issue the data service.

[0003] Since the location of the mobile stat...
