Problems solved by technology

However, there is no signaling interaction between the CF entity and the PF entity related to the media processing strategy. That is to say, the CF entity cannot instruct the PF entity to process the media stream through the signaling interaction process with the PF entity. Therefore, Greatly reduces the flexibility of realizing multi-party communication services and reduces the service quality of the system

Embodiment Construction

[0057] The present invention proposes a method for realizing multi-party communication services, the core idea of ​​which is: the CF entity in the multi-party communication sends the media processing strategy to the PF entity; the PF entity processes the media stream from the terminal according to the received media processing strategy.

[0058] The multi-party communication service described in the present invention can be, for example, a push-to-talk (POC) service based on a cellular network, a three-party call, a conference call, a chat room session, CALL HOLD or CALLWAIT, and the like.

[0059] Fig. 1 is a schematic structural diagram of the system of the present invention. Referring to Fig. 1, the system for implementing multi-party communication services proposed by the present invention includes: a CF entity and a PF entity in multi-party communication, the CF entity includes a media policy delivery unit, and the PF entity includes a media processing unit, wherein,

Abstract

The system thereof comprises: a control function (CF) entity and a participating function (PF) entity. The CF entity sends the media processing strategy to PF entity; PF entity processes the media stream sent from terminal according to the received media processing strategy. In the invention, CF entity can control the multipartite communication by interacting signaling with PF entity such as: the media stream is only transmitted between PFs, and there is no need to relay the media stream through CF entity.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for realizing multi-party communication services. Background technique [0002] With the rapid development of mobile communication technology, multi-party communication services have been widely used by people. In the multi-party communication service, the system side is equipped with a participating server (PF) and a control server (CF) for centralized control. Each user in the multi-party communication accesses a CF entity through the PF entity to which it belongs. [0003] During multi-party communication, the user sends its own signaling or media stream to the PF entity to which it belongs, and the PF entity then sends the received signaling or media stream to the CF entity, and the CF entity controls the subsequent signaling transmission or the process of media streaming. For example, in a multi-party communication, a user's speaking request is...
