Embodiment Construction

[0032] 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.

[0033] In order to realize the negotiation of IMS service capability in the IMS network, the present invention provides two ways:

[0034] In the first way, the UE in the IMS network can carry its own IMS service capability information in the Initial Session Protocol (SIP) message and send it to the network entity in the IMS network, and the network entity in the IMS network adopts the received After the IMS service capability information of the UE carried in the SIP message updates the IMS service capability information of the UE set by itself, the updated IMS service capability information of the UE is carried in the SIP message and sent to the UE, and the UE adopts the information carried in the SIP message The updated IMS service capab...

Abstract

This invention discloses a method of realizing Internet Protocol Multimedia Subsystem-IMS service capability consultation. The method includes: one entity of the two entities of IMS send initial conversation protocol SIP information which takes IMS service capability information to the other entity. After the other entity receives IMS service capability information which SIP information takes, itupdates IMS service capability information which itself sets to the other entity.The method of this invention makes it fulfill the IMS service capability consultation in IMS internet.

Description

technical field [0001] The invention relates to the technology of capability negotiation in Internet Protocol Multimedia Subsystem (IMS), in particular to a method for realizing IMS service capability negotiation. Background technique [0002] With the development of broadband networks, mobile communication systems are 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 user terminals by combining with data services such as presence, short message, web page (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, with the purpose of using a standardized open structure in the mobile communication system to realize a variety of multimedia service applications and provide us...
