Problems solved by technology

However, as the operator's network scale expands, the logical functions of the P / S-CSCF will inevitably be distributed on different physical entities. At this time, this method cannot continue to be used.

Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] The types of authentication capabilities supported by the UE and the P-CSCF mentioned in this application document match. If the above two do not match, the current 3GPP protocol has described the processing method of the P-CSCF. That is to say, the mismatch between the above two is out of the scope of the present invention.

Abstract

Key points of the method are that after obtaining information of S-CSCF capability set capable of providing service for the UE from HSS, I-CSCF determines type of authentication capability supported by UE of initiating request; based on coincidence relation between S-CSCF id in already setup data list and the said type of authentication capability supported, as well as obtained information of S-CSCF capability set capable, I-CSCF selects S-CSCF set, which can satisfy operation capability required by UE, and supports type of authentication capability supported by UE, and chooses one S-CSCF from the selected S-CSCF set; then, according to current method to continue next registration process. The invention guarantees match of types of authentication supported between UE of initiating request and S-CSCF. Features are: small modification to current technical scheme and good compatibility to current technique.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing registration in an IP multimedia subsystem (IMS). Background technique [0002] With the development of broadband network, mobile communication is not limited to traditional voice communication, but through the combination with data services such as presence, message, webpage (WEB) browsing, location information, push service (PUSH) and file sharing , mobile communication can implement services of various media types such as audio, video, picture and text, so as to meet various needs of users. [0003] Organizations such as the 3rd Generation Partnership Project (3GPP) and the 3rd Generation Partnership Project 2 (3GPP2) have successively launched the IP-based Multimedia Subsystem (IMS) architecture, which aims to use a A standardized open structure to achieve a variety of multimedia applications to provide users with more choices and richer e...
