Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] The present invention is a distributed optimization processing method for media stream transmission of POC services. The method is based on the transmission control protocol MTP of OMA and its improved mechanism-transmission control optimization protocol MTO, aiming at the RTP media of the POC-4 interface. Stream, the proposed distributed media stream optimization method, namely DMTO, optimizes the RTP stream of the POC-4 interface to reduce the sending burden of the CS and reduce the network traffic of the POC-4 interface.
[0023] The method of the present invention is to add the function of logical judgment at the POC control server CS, that is, the CS can judge whether to send a copy of RTP data to the PS according to the real-time status information of ...

The invention discloses a distributed optimizing processing method for media-stream transmission of a POC service. A function of logic judgment is added at a control server CS of POC, whether one part of RTP data is sent by the CS to PS is judged according to real-time state information of each POC user terminal subordinate to a specific participant server PS, and a function of recording an address, a port and a real-time communication state of the subordinate each POC user terminal is added at the PS so that the PS can determine the copy parts of copying the RTP data according to the state of each POC user terminal, and the PS copies and dispatches the RTP data according to the information record of the POC user terminal so as to dispatch the copy dispatch function of the RTP data at the CS to each PS as much as possible, thereby the dependence degree of the CS by a network system is reduced, the load of the CS is lightened, and the queue time delay of the media-stream at the CS is shortened. Aiming to carry out the distributed optimizing processing method for the RTP media-stream of a POC-4 interface, the invention reduces the network flow of the POC-4 interface and reduces media-stream transmission time delay.
Description
technical field [0001] The present invention relates to a method for improving or optimizing a new service based on 3G, to be precise, relates to a distributed optimization processing method for media stream transmission of a push-to-talk POC service of 3G technology, which belongs to the communication of 3G new service technology field. Background technique [0002] With the third generation of 3G (3 rd Generation) mobile communication technology is developing rapidly, and the POC (Push to Talk over Cellular) service, which is one of the 3G symbol applications, has also attracted widespread attention. POC is a two-way, instant, and multi-party cluster communication service, allowing one-to-one or one-to-many instant communication. Users only need to press a button to communicate with the network quickly and directly without dialing, just like using a walkie-talkie. Multiple users within the coverage area realize half-duplex communication. Therefore, POC mobile phones are...
