Problems solved by technology

[0004] However, the existing IMS network adopts the client / server mode, so it is hoped that the P2P technology can be applied to the IMS network to realize the integration of the two, so as to provide users with better services, but there is no such method in the prior art. better integration

Embodiment Construction

[0037] Aiming at the problems existing in the prior art, the present invention proposes a P2P technology realization scheme in the IMS network. Set the content application server (ContentAS), content index server (ContentTS) and content data server (ContentDS) in the IMS network in advance, such as figure 1 as shown, figure 1 A schematic diagram of the IMS network structure provided with ContentAS, ContentTS and ContentDS for the present invention. Usually, only one ContentAS is set, while the number of ContentTS and ContentDS is usually more than one, more than ten or dozens, and the specific number can be determined according to actual needs. Among them, the ContentAS server is mainly used to cooperate with network elements such as the existing proxy call session control function entity (P-CSCF, Proxy-CallSessionControlFunction) and service call session control function entity (S-CSCF, Service-CallSessionControlFunction) in the IMS network to complete UE Authorization veri...

Abstract

The invention discloses a method, system and device for realizing a peer-to-peer technology in an IMS (IP multimedia subsystem) network. The method comprises the following steps: a content application server (AS), a content index server (TS) and a content data server (DS) are preset in the IMS network; user equipment (UE) registers in the content AS, acquires a content list, selects contents needed per se and carries an identifier of the selected contents in a content acquisition request and transmits the identifier to the content AS; the content AS selects the content TS for the UE and informs the UE; the UE is connected to the selected content TS and requests for a UE list which corresponds to the selected contents; the selected content TS generates a UE list which corresponds to the contents selected by the UE according to a preconfigured strategy, and transmits the content DS which corresponds to the contents selected by the UE to the UE; and the UE establishes a data transmissionchannel with each UE in the UE list and the content DS which corresponds to the selected contents for data downloading and uploading. Due to the application of the scheme of the invention, the infusion of the IMS network with the peer-to-peer technology can be well realized.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a point-to-point technology realization method, system and device in an IP Multimedia Subsystem (IMS, IPMultimediaCoreNetworkSubsystem) network. Background technique [0002] At present, the IMS network is considered as the core technology of the next generation network, which can provide a new multimedia service form, meet the newer and more diversified service requirements of the terminal, and can solve the integration problem of mobile and fixed network, as well as voice Integration of differentiated services such as , video and data. [0003] Peer-to-peer (P2P, peer-to-peer) technology is a technology widely used in the Internet. Compared with the traditional client / server mode, P2P technology provides a new way of information exchange. In the client / server mode, a dedicated server is used for data distribution, and all user terminals (UE, UserEquipment) obtain data...
