Problems solved by technology

[0004] However, the hierarchical structure of the all-IP broadband mobile network is in stark contrast to the flat structure of P2P. In the Internet, peer nodes are directly connected to efficiently search and interact with resources; while the mobile network is based on a hierarchical structure, Can not directly use the current technology in the Internet

Embodiment Construction

[0020] The system and method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Embodiment of the P2P system of the all-IP broadband mobile network: the present invention provides a P2P system structure of the all-IP broadband mobile network suitable for multiple access modes of mobile users. Below to figure 1 As an example, the entity selection and functions of the P2P two-dimensional overlay network architecture in the all-IP broadband mobile network are described in detail.

[0022] see figure 1 As shown, the entities in the architecture include RAN (Radio Access Network), ERAN (Evolved Radio Access Network), NON-3GPP (Non-3GPP Access), SGSN (Serving GPRS Support Node), MME (Mobility Management Entity ), SAE Servering GW (SAE Service Gateway), PCRF (Policy Control and Charging Function), and IMS network.

[0023] In order to arrange the P2P overlay network under the hierarchical structure of SAE, the SAE PDN...

Abstract

The invention discloses a P2P system applicable to an all-IP broadband mobile network and a content sharing method, relating to the field of mobile data communication and aiming at introducing a P2P technology into the all-IP broadband mobile network. The system consists of SuperNodes and Clients connected with the SuperNodes; each SuperNode in a mobile network consists of P-GW and DSS; mobile SuperNodes and fixed SuperNodes included in the system form two-dimensional covering networks: the first two-dimensional covering network is a structural covering network of DHT formed among all the SuperNodes; and simultaneously, the second two-dimensional covering network is FIooding clusters formed by information exchange between adjacent SuperNodes. The method comprises the steps of sharing content releasing, sharing content searching and sharing content downloading.

Description

technical field [0001] The invention relates to the field of mobile data communication, in particular to a P2P system and a content sharing method suitable for an all-IP broadband mobile network under multi-access mode and multi-network integration. Background technique [0002] P2P (Peer-to-Peer) networking has become the hottest application in recent years. P2P makes full use of resources at the edge of the network, and distributes the tasks that were originally completed on the centralized server to the user side, thereby reducing costs. P2P-based services provide large-scale users with better quality applications, reduce operators' investment and maintenance costs, and improve market competitiveness for operators. The key to the P2P network is to provide user resource storage, location and search key functions. Based on these core functions of P2P, various application services such as voice communication, streaming media video and online games can be carried out to prov...
