Embodiment Construction

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

[0021] An embodiment of the P2P system of an all-IP broadband mobile network: The present invention provides an all-IP broadband mobile network P2P system structure suitable for multiple access modes of mobile users. Below 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 explained 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 (GPRS service 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 deploy the P2P overlay network under the hierarchical structure of SAE, SAE PDN GW (SAE Packet Data G...

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 present invention relates to the field of mobile data communication, in particular to a P2P system and 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) network has become the most popular application in recent years. P2P makes full use of the resources at the edge of the network, and distributes the tasks originally completed on the centralized server to the user side for completion, thereby reducing costs. P2P-based services provide high-quality applications for large-scale users, reduce operator input 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. These core functions based on P2P can carry out various application services such as voice communication, streaming media video and online games, and provide u...
