Problems solved by technology

An important reason for this implementation is that the audio and video media server and data media server are independent, and it is difficult to integrate the two together. Therefore, there are almost no mature solutions that implement both audio and video media services and data media services. Media Server (MS)

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0036] figure 2 It is the signaling flow chart when the conference originator requests to hold a conference and to close a conference media channel. The following is combined figure 2 , for a further detailed description of the specific implementation of AS in each signaling process:

[0037] 1. The conference originator initiates a meeting request through the Invite message, and the SDP of the Invite message carries the media type (audio, vedio, application, wb) of the conference that the conference originator wishes to hold; after receiving the Invite message, the AS sends the The SDP in the message is saved, and then the m lines of the SDP are decomposed, and the m lines are divided into audio and video categories (audio, vedio) and data categories (application, wb), and the SDP is decomposed into two new SDPs according to the ...

Abstract

The present invention relates to a method and apparatus for controlling multimedia conference by an application server. The method includes that in a multimedia conference, the application server disassembles m rows in terminal session description protocol message SDP received by terminals into two SDPs, and respectively transmits to an audio / video medium server and data medium server, or assembles the SDPs returned back form the audio / video medium server and the data medium server as a SDP, and transmits to the terminals. The apparatus includes an application server including an SDP disassembling module and an SDP assembling module. The present invention simplifies signalling interaction flow path, reduces the consumption in the signalling interaction; better synchronizes the control of traditionary audio / video medium and the data medium, thereby the realization of multimedia customer terminal is still more simple; simultaneously can compatible terminals that can not traditionarily support data medium.

Description

technical field [0001] The invention relates to the multimedia conference technology in the IMS network or the NGN network, in particular to a method and device for controlling a multimedia conference by an application server (AS). Background technique [0002] Traditional multimedia conferences refer to audio and video conferences. Even if some multimedia conferences implement the function of data conferences, from the perspective of implementation and signaling, data conferences and audio and video conferences are still independent. It is integrated with the function of audio and video conferencing. An important reason for this implementation is that the audio and video media server and data media server are independent, and it is difficult to integrate the two together. Therefore, there are almost no mature solutions that implement both audio and video media services and data media services. media server (MS). Such as figure 1 As shown, it is a schematic diagram of the...
