Problems solved by technology
Various conferences use MRS (Media Resource Server, Media Resource Server) to realize the transmission of media information. At present, the MRS used in conferences generally only supports a single media type, such as only audio, video, or data services, which cannot Meet people's needs for conference services where multiple media types coexist, and cannot complete the task of combining multiple media types for conference services

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] refer to figure 1 , in this embodiment, terminal A as a conference controller and terminal B as a conference member belong to the same HSS (Home Subscription Server, Home Location Server) and S-CSCF (Serving Call Session Control, Serving Call Session Control Function ). It includes the following parts: terminal A, terminal B, P-CSCF (Proxy Call Session Control, proxy call session control function), I-CSCF (Interrogating Call Session Control, interrogating call session control function), S-CSCF, HSS, ConfAS, three One MRS that supports different media types, that is, MRS_1, MRS_2, and MRS_3, supports audio, video, and data conference services respectively. In terms of communication connection, each network element is connected through a TCP / IP network, and SIP (SessionInitiation Protocol, application control layer protocol) is used to interact between each term...

The present invention discloses a method of building a conference combining multiple media types, which has five steps. Firstly, the terminal of a conference control party sends a conference buildingrequest message containing the media capability information of the terminal and the information of conference members to a Conf AS; secondly, according to the media capability information of the terminal of the conference control party, the Conf AS realizes the media capability negotiation between the terminal and each MRS corresponding to the media type contained in the media capability information of the terminal; thirdly, according to the information of conference members, the Conf AS ordinally sends a conference invitation message to every conference member; fourthly, each of the terminalsof the conference members respectively returns a conference invitation response message containing the media capability information of the terminal to the Conf AS; and finally, after receiving each conference invitation response message, the Conf AS ordinally realizes the media capability negotiation between each terminal and each MRS corresponding to the media type contained in the media capability information of the terminal according to the media capability information of each of the terminals of the conference members. The technical scheme of the present invention realizes a conference combining multiple media types.
Description
technical field [0001] The invention relates to a method for creating a meeting, in particular to a method for creating a combination meeting of various media types. Background technique [0002] At present, conferences of various media types, such as voice conferences and video conferences, are being popularized and playing an increasingly important role. They are becoming more and more popular in IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) and NGN (NextGeneration Network, next-generation communication network) has a good development prospect. Various conferences use MRS (Media Resource Server, Media Resource Server) to realize the transmission of media information. At present, the MRS used in conferences generally only supports a single media type, such as only audio, video, or data services, which cannot To meet people's needs for conference services where multiple media types coexist, it is impossible to complete the task of combining multiple media types for...
