Abstract  Abstract

This invention claims a IMS register triggering realization method which comprises the following the steps network side or initial triggering user sends IMS register triggering orders and IMS register triggering indication information to user needed IMS register in order to indicate the user needed IMS register to send IMS register to IP multi-media subsystem; according to the IMS register triggering indication information the user needed IMS register is triggered to start IMS register to the IP multi-media subsystem. Since the network side or initial triggering user triggers the IMS register of the called user it can be avoided that the user needing a register has no IMS register which leads to the problem that it is impossible to send SIP messages to the user and to have IMS conversation.

A method of realizing IMS registration trigger in IP multimedia subsystem which includes: network side or a user initiating trigger sends IMS registration trigger cuing information to the user needing IMS registration so as to cue the user needing IMS registration to initiate IMS registration to IP multimedia subsystem; the user needing IMS registration is triggered to initiate IMS registration to IP multimedia subsystem according to the IMS registration trigger cuing information. Due to the fact that IMS registration of the called user is triggered by network side or the user initiating trigger the problem that SIP message cant be sent to user and IMS session cant be carried on due to the user needing IMS registration doesnt IMS registration is avoided.
