Abstract

The invention discloses method, system and device for attaching to a P2P network and acquiring IPTV content. The method for attaching a terminal to a P2P network based on an IP multimedia subsystem comprises the following steps: user equipment acquires a P2P network attachment message by an IMS network and is attached to the P2P network according to the P2P network attachment message. By the embodiment of the invention, the UE can download by a P2P way among UEs, thereby alleviating the load of a media server and reducing system investment. In the embodiment of the invention, available P2P network attachment message is provided to the UE according to the area where the UE is located, thereby dividing the UEs by areas so that P2P flow among UEs can be limited in a local part and out-of-order domain flow does not happen.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, system and device for attaching to a peer-to-peer network and obtaining content of an Internet TV (IPTV, IPTeleVision) based on an IP multimedia subsystem (IMS, IPMultimedia Subsystem). Background technique [0002] Streaming media service or IPTV 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 switching network. The content is immediately playable when accessed without a full download. The key technology of streaming media is streaming transmission technology, and streaming transmission technology is to put continuous video and audio information on the server after processing, so that users can watch and listen to it while downloading, without waiting for the entire file to be...
