Problems solved by technology

In addition, because a SIP session contains a variety of media, a voice RTP session can coexist with multiple MSRP sessions for file transfer. In the case of certain physical resources, if the number of MSRP sessions is not limited, it will inevitably lead to Voice session quality drops significantly, affecting call quality
Therefore, there are following disadvantages in the prior art: poor user experience and waste of network resources

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Figure 2 shows the architecture diagram of PoC.

[0035] It can be seen from the PoC architecture diagram that the PoC functional components mainly include a PoC client, a PoC server, an XML document management client, and a PoC XML document management server. The PoC server can be logically divided into a control function server and a participation function server. Of course, these two logical function servers can also be executed by a physical PoC server at the same time.

[0036] In the present invention, it mainly involves the media and media control signaling flow between the PoC client and the PoC server, that is, the transmission of the media transmission request, the media content, and the transmission of the response message. These processes all use the PoC- 3 The interface interaction is completed.

Abstract

The present invention provides a media transferring method in the group communication and a client end for participating the group communication. The method comprises a server receives a request message of the calling client end for transferring media, the server judges and confirms the called client end according to the request message for transferring media, and transmits the request message for transferring media to the called client end participating the group communication; the called client confirms, and the server transmits the media to the confirmed called client end. The called client end comprises a request message for receiving of the transferring media transmitted by the server, and an input end for receiving the media transmitted by the server according to the indication message of receiving media transmitted by the server; a processing unit for judging whether the media processing unit is received according to the request message for transferring the media transmitted by the server; an output end used for transferring message receiving confirmation or message receiving refusal to the server according the judgment result of the processing unit. The user experience can be increased and the network resources are saved by utilizing the present invention.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for transmitting media in a group conversation and a client participating in the group conversation. Background technique [0002] Push-to-Talk Over Cellular ("PoC") is a PTT (Push to Talk) service implemented on a packet network defined by the Open Mobile Alliance ("OMA"). Packet voice (Voice over IP, referred to as "VoIP") technology and a half-duplex mode meet the real-time communication needs of the client with low cost and high efficiency. Through this service, the client can initiate a PoC session to a single client or a group, realizing a one-to-one or one-to-many session. [0003] OMA is based on the Session Initiation Protocol (SIP for short) and Real-Time Transfer Protocol (RTP for short) defined by the Internet Engineering Task Force (IETF for short). To define PoC. With the development of PoC services, new media contents appear in PoC2.0. In addition to...
