Problems solved by technology

However, the SIP protocol in IMS is generally used for conversational services such as voice and video. There is no special protocol specification for P2P file sharing services, and there is a lack of means to control shared files.

Embodiment

[0055] The network architecture of peer-to-peer file sharing service (IPFSS) based on Internet Protocol Multimedia Core Subsystem is shown in Figure 2. Its functional entities include both the core functional entities in IMS and the new functional entities of IPFSS. IMS network core functional entities mainly include: P-CSCF, I-CSCF, S-CSCF, HSS and so on. Wherein: P-CSCF is equivalent to a proxy server in SIP, and is used for receiving and forwarding SIP signaling. P-CSCF is the entry point of IPFSS. It performs bearer resource authentication and QoS management, and searches for the corresponding I-CSCF for users, realizes QoS management and generates charging information. The I-CSCF and S-CSCF are located in the user's home network. The I-CSCF hides the home network topology and specifies the S-CSCF for the user through the HSS. S-CSCF performs user session control and service management, performs registration server functions in user registration, and performs SIP proxy fu...

Abstract

This invention relates to a signaling control method for peer-to-peer networking share service based on IMS including: setting, modifying and stopping data connecting channels for downloading files among peer-to-peer user entities in IMS network with a signaling control method of the SIP protocol and registering and refreshing and eliminating the registration of shared file information then to use the control method to search and feed back the search result, in which, it's not necessary to set up independent control signaling protocols since this invention applies the SIP protocol as the service control signaling that is helpful to set up P2P file shared service on the basis of IMS and guarantee conformity of signaling protocols.

Description

technical field [0001] The present invention relates to a network control method, more specifically, the present invention relates to a signaling control method of peer-to-peer network sharing service based on IMS (Internet Protocol Multimedia Core Subsystem). Background technique [0002] Session Initiation Protocol (SIP) is an application layer control protocol for multimedia communication on IP networks proposed and standardized by the Internet Engineering Task Force (IETF). It is used to create, modify and terminate sessions attended by one or more participants. , and provide negotiation of terminal communication capabilities. The SIP protocol is simple in structure, strong in scalability and good in network compatibility. SIP is a text-based protocol, and the realization of SIP protocol functions is completed by a series of SIP protocol messages. SIP protocol messages are divided into request messages sent by the client to the server and response messages sent by the ...
