Problems solved by technology

The SIP protocol does not define the event to initiate customization, and the customized event cannot be completed by the customized event, which makes it difficult for the operator to control the customized server or realize the cache service function through the SIP protocol. The SIP protocol must be extended
Since the addition of new SIP message types will lead to a large-scale upgrade of the IMS network, which is not conducive to the development of services, the control signaling of customized services must use the existing SIP protocol message types

Embodiment 1

[0064] The present invention uses the peer-to-peer networking file sharing service (IPFSS) network architecture based on the Internet Protocol Multimedia Core Subsystem, such as figure 2 As shown, the functional entities of the network architecture include not only the core functional entities in the IMS, but also the new functional entities of the 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 manag...

Embodiment 2

[0096] In this embodiment, a user entity with a customized service function is used to replace the customized server (SS) in Embodiment 1. The process of customizing a UE to customize a file download task to a customized UE with a customized function (that is, a user entity with a customized service function) is the same as The customization process is the same as that of SS. The customized UE performs the function of ordinary UE to complete the download of the customized file from the IPFSS network and notifies the customized UE. The customized UE executes the file download function within the storage time to download the customized file from the customized UE. In many cases , the customized UE only wants the customized UE to complete the custom file download event, and does not need to download the file from the customized UE after receiving the notification of the completion of the customized file download. An example is that the user owns a PC and a mobile phone, and the two...

Abstract

The invention relates to a P2P customized services signaling control method based on IMS, which includes the following steps: a customized user entity in the IMS network sends out customization request information to a customized services entity; the customized services entity sends out request invitation information to a target user entity, according to the customized information from the customized user entity, and requests to establish a TCP data connection to download files with the target user entity; the target user entity transmits target file data on the established TCP data channel and at the same time, the customized services entity receives and stores the target file data; the customized services entity sends out notice request information to the customized user entity for the TCP data disconnection after the completion of the data transmission. The invention adopts SIP protocol standard request and response information, with no additional SIP information type, and realizesthe customization function with no large-scale upgrading of the IMS network.

Description

technical field [0001] The invention relates to a network control method, more specifically, the invention relates to an IMS-based peer-to-peer networking customized service signaling control method. 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 server to the client. [0003] The Internet Multimedia Core ...
