Embodiment

[0041] This embodiment is based on the IMS network architecture, as shown in FIG. 2 , including a home network and a visited network. A mobile subscriber is registered with a home network and can move or roam to a visited network. Since IMS has nothing to do with access, UEs can include wireless users and wired users. Wireless users are connected to P-CSCF through IP connectivity network (IP-CAN) and connected to IMS network; wired users are directly connected to IMS network through P-CSCF. Wireless or wired users are connected to the IPFSS network through the P-CSCF of the IMS, and the index server is connected to the S-CSCF of the IMS. Control signaling between user entities and between user entities and the index server is processed and forwarded through P-CSCF, I-CSCF and S-CSCF. The customized server and cache server are connected to IPFSS through P-CSCF, and are connected to the Internet P2P at the same time.

Abstract

The invention relates to a P2P file-sharing service network framework, comprising a user entity, an Agent-Call Session Control Function entity, a Timetable-Call Session Control Function entity, a Service-Call Session Control Function entity, an application server, and an attribution user server. The invention is characterized in that the application server is an index server to realize P2P file-sharing service. The user entity is provided with a P2P file-sharing service function module; the index server is respectively connected with the attribution user server and the Service-Call Session Control Function entity; the user entity is connected with the Agent-Call Session Control Function entity. The invention can effectively realize the discontinuity of the mobile and roaming services of the users, allow wired and wireless users to participate simultaneously, and realize uniform standard protocol specification, provide effective management and copyright protection, improve service performance by a buffer, and expand service contents by a custom server.

Description

technical field [0001] The invention belongs to the field of computer and communication network services, in particular, the invention relates to a peer-to-peer (P2P) file sharing service network architecture. Background technique [0002] The rapid development of P2P services on the Internet has even changed the status quo of the Internet to a certain extent. What directly triggers the upsurge of P2P technology is the demand for file sharing and exchange services. On the one hand, P2P services have achieved great success on wired networks; on the other hand, mobile operators are looking for new application services and actively expanding service content. It can be predicted that providing P2P services on wireless networks will have broad prospects, but this is both an opportunity and a challenge. [0003] The actual application of P2P services on 2G / 2.5G mobile networks encounters great difficulties, including: the mobile terminal is located behind the GPRS Gateway Support...
