Embodiment 2

[0159] Embodiment two: in embodiment one, the negotiation of RTSP and RTP is all finished in the user's program request process (step 3~13), and in embodiment two, only finish the negotiation of RTSP in this process, and in follow-up In the step, RTP parameters are negotiated through RTSP interaction, and SSAF realizes the proxy function of RTSP at the same time. Specifically, in the process described in Embodiment 2, only the address and port number of RTSP are negotiated, and the AS / MRF returns the address / port number of RTSP to the terminal (the address / port number of RTP is returned at the same time in Embodiment 1), An RTSP connection is established between the terminal and the MRF, and the RTP address / port number is negotiated during the RTSP interaction process to establish the RTP connection and transmit the media stream.

[0160] In the above-mentioned network architecture in which MRFC completes MRLF-related functions, the flow chart of implementing streaming media s...

Abstract

The method includes following steps: (1) determining media resources functional entity MRF providing service for request of stream media service from user equipment UE; (2) providing stream media service for user by determined MRF. Overcoming disadvantages of current technique, the invention uses original functional entities in NGN, and adds new functional entities to implement stream media service. The invention implements uniform authentication for users, charging, and managing etc, supporting functions; uses existed sub system in NGN network architecture provides supports for stream services including aspects of media resources supply, distributing and guaranteeing QoS. The invention also supports development of value added service based on stream media.

Description

technical field [0001] The present invention relates to the technical field of streaming media, and specifically relates to the technology of realizing streaming media service in NGN. Background technique [0002] Streaming media service or IPTV (Internet Internet Television) service is a new service that has developed rapidly in recent years. The streaming media service uses streaming transmission technology to transmit multimedia files, including video, audio and other file content, on a packet-switched network. The key technology of streaming media is streaming transmission technology, its main feature is to put continuous video and audio information on the website server after processing, so that users can watch and listen while downloading, without waiting for the entire file to be downloaded to their own machines Only after the network transmission technology can be viewed. [0003] However, there is no unified standard for existing streaming media network and IPTV ne...
