Abstract

The present invention proposes an interworking method of calling each other at the same time by subscribers in an IMS communication system. The method comprises following steps that if the system detects a subscriber in calling and called subscribers opens a calling conflict service and the calling and called subscribers call each other at the same time, one path in two independent callings initiated by the calling and called subscribers is removed according to a calling conflict handling strategy, and the other path of calling is connected. According to the method, the problem of a calling failure when two subscribers call the other side at the same time is solved based on the service realization of the IMS, the involved net elements of the IMS are few, and the method is realized purely in a service way and is not does not involve hardware changes.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an intercommunication method when users simultaneously call each other in an IMS communication system. Background technique [0002] In the existing IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) communication system, the system equipment detects that the called user is busy, and will play a failure tone indicating that the opposite end user is busy to the calling user. When two users call each other at the same time, both parties will If you hear the busy signal from the opposite end and then release the call, the call cannot be connected. What's worse, both parties keep calling each other, resulting in the call being unable to be connected. This not only causes unnecessary waste of resources to the system but also causes poor user experience. Contents of the invention [0003] In order to overcome the defect that the existing IMS communication system cannot inte...
