Embodiment Construction

[0071] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0072] Since different methods can be used when setting the GRUU for the user, different validity checking methods must also be used when checking the validity of the GRUU set by the user.

[0073] When setting the GRUU for the user, the existing technology can adopt two methods: one is for registration generation, when the user registers to generate the GRUU, the GRUU generated by the registration is stored in the S-CSCF that performs services for the user, and the S-CSCF also Save the validity information of whether the GRUU generated by registration is currently valid. Usually, the users generated by registration are all UEs; the other is management generation. When GRUU is generated under user management, the GRUU generated by managemen...

Abstract

The disclosed method for checking GRUU validity comprises: A. the IMS NS receives user business process request or response carried user-set GRUU; B. for GRUU generated by management way as pre-set rule, the IMS NS sends the request or response to an AS to check user-set GRUU validity according to stored validity message; and C. for GRUU generated by register way or other way as pre-set rule, the IMS NS sends the request or response to a S-CSCF for checking validity.

Description

technical field [0001] The present invention relates to the technology of processing Generic Routable User Agent Uniform Resource Identity (GRUU) in Internet Protocol Multimedia Subsystem (IMS), in particular to a method for checking the validity of GRUU in IMS. Background technique [0002] With the development of broadband networks, mobile communication is not limited to traditional voice communication, but can also combine multiple media services such as audio, video, pictures and text. A variety of media services can meet various needs of users by combining with data services such as presence, short message, webpage (WEB) browsing, location information, push service (PUSH) and file sharing. [0003] Driven by a variety of data service applications, standard organizations such as 3GPP and 3GPP2 have successively launched the IMS architecture, aiming to use a standardized open structure in the mobile network to realize a variety of multimedia service applications and provi...
