Problems solved by technology

[0013] At present, the shortcoming of using the existing 3GPP-defined streaming media broadcast and multicast method to realize the business process of the streaming media service is that the terminal and the wireless network need to support a special multicast signaling channel (MICH). The networking of the network has changed a lot, especially after the 3G network is deployed, it is almost unacceptable to make such a big change to the terminals and wireless networks that have been put into use; the process is quite different from that of the unicast streaming service , the terminal needs to implement two different processes

Embodiment Construction

[0030] Referring to shown in Fig. 3, Fig. 3 is a principle flow chart of the present invention, and this flow process comprises the following steps:

[0031] Step 200: The terminal clicks the link on the streaming media portal, and sends an RTSP link request message corresponding to the multicast content to the streaming media portal on the network side. After the streaming media portal receives the request, the streaming media portal sends the The terminal replies with a confirmation message for receiving the message, and the terminal obtains the RTSP link;

[0032] Step 201: The terminal sends a request message based on the RTSP link to establish an RTSP connection to the streaming media server; the terminal negotiates the RTP port number with the streaming media server; After the negotiation, reply the negotiated RTP port confirmation message to the terminal, and complete the negotiation with the terminal RTP port number;

[0033] Step 202: The terminal sends a request mes...

Abstract

A method for providing multicast based on play command of server includes sending message of RTSP link request corresponding to multicast content to stream media port at network side by terminal, obtaining RTSP link by said terminal, consulting RTP port number with stream server by terminal, sending request message of playing stream media data based on RTSP link to stream media server by terminal, sending message with multicast content to radio network controller by said server, setting up multicast channel between RTP port of terminal and said controller by said controller according to received message in order to transmit stream media data to terminal.

Description

technical field [0001] The invention relates to a method for realizing a streaming media service, in particular to a method for providing multicasting based on a server's broadcast instruction to realize the streaming media service. Background technique [0002] Streaming media service is a multimedia application service developed from the Internet. Streaming media refers to continuous time-based media using streaming technology, such as audio, video or multimedia files. [0003] Streaming media communication technology has been widely used in various industries and fields of society, affecting the way of life and quality of life of human beings, especially in the telephone network (including fixed and mobile telephone networks), broadcasting network, computer network applications have achieved rapid development . Streaming media technology is widely used on the Internet, such as video on demand, online cinema, telemedicine, distance education, interactive TV, etc., to meet...
