P2P (Point-to-Point) streaming media system, P2P user equipment and streaming media data transmitting method

Abstract

The invention discloses a P2P (Point-to-Point) streaming media system which comprises a source server, a caching server, a streaming media key application server and an IMS (IP Multimedia Subsystem) key network element, wherein the source server stores streaming media contents; the caching server caches streaming media data and sends to P2P user equipment; the streaming media key application server is interacted with the caching server to generate program information, obtains owned streaming media data information and current state information reported by the P2P user equipment through the IMS key network element, and provides corresponding program information and resource information for the P2P user equipment requesting streaming media service; and the IMS key network element accesses the P2P user equipment into an IMS network and controls the connection negotiation among the P2P user equipment, the caching server providing the downloading of the corresponding streaming media data and other P2P user equipment. The invention also provides the P2P user equipment and a streaming media data transmitting method. The invention realizes that the P2P user equipment is accessed into the IMS network through the IMS key network element for controlling the streaming media service.

Description

technical field [0001] The present invention relates to streaming media transmission, in particular to a P2P streaming media system for realizing peer-to-peer network (Peer to Peer, P2P) streaming media transmission through IP multimedia subsystem (IP multimedia subsystem, IMS), corresponding P2P user equipment and streaming media Data transfer method. Background technique [0002] The IMS technology proposed by 3GPP improves the mechanism of separation of service logic and control, call control and bearer control on the basis of softswitch, and optimizes the signaling plane. In addition, the IMS system has many advantages such as end-to-end all-IP, independent access mode, and horizontal service development mechanism, and has quickly been widely recognized by other standardization organizations. It has changed from the initial 3GPP definition for mobile users The system is extended to a unified core network for fixed-mobile convergence. [0003] The core idea of ​​P2P is ...

AI Technical Summary

Problems solved by technology

[0004] Although the existing P2P system realizes low-cost service provision, due to the lack of corresponding management and control of the connection between the participating nodes in the network on the network side, the data interaction between the participating nodes cannot be effectively controlled, and the data interaction between the participating nodes cannot be obtained. The data traffic actually used by participating nodes in the network makes it impossible for operators to compare streaming media services b
