Example Embodiment

[0048] Example one

[0049] In order to realize the IMS capability query request, this embodiment will provide a solution. The typical network architecture of the system is as follows: image 3 Shown. Based on the traditional IMS network, this network architecture diagram deploys an AS to process SIP OPTIONS messages. In this embodiment, the calling user is the capability query request terminal, the target user is the target terminal, the capability query request is the SIP OPTIONS request, and the capability query response is the SIP OPTIONS response.

[0050] The specific SIP OPTIONS capability query process is as follows Figure 4 As shown, it includes the following steps: S301, calling user A initiates SIP OPTIONS capability query requests for multiple target users to IMS Core, namely target user B and target user C. The message sample is similar to the following (non-critical header fields are omitted ):

[0069] In order to further reduce the message flow of the target client network, a storage unit is set up in the AS. The AS can temporarily save the queried user capability information to the storage unit. During the information validity period, for the target user's ability query request, if the storage unit stores the target terminal's ability information, the ability information in storage can be used directly without sending the ability query request to the target terminal; the expired ability information in the cache The AS is deleted from the storage unit, and the next time there is a corresponding target capability query request, it is again obtained from the target terminal and stored in the storage unit. In this embodiment, the calling user is the capability query requesting terminal, and the target user is the target terminal. The process is like Figure 5 As shown, specifically including the following process:

[0070] S401: The calling user E ini...

Example Embodiment

[0078] Example three

[0079] For the user terminal, when the terminal is running in a non-interactive state, such as standby, watching video, or listening to music, the capability query request function can be suspended at this time; when the terminal is running in an interactive state, that is, it has functions for the terminal within a specified time Operational behavior and the state in which the terminal can respond to it. The user uses the request terminal for IM communication, video chat, file transfer, or voice call. For example: when IM communication, video chat, file transfer, voice call, the capability query request function is activated. In this embodiment, the target user is the target terminal. Image 6 To achieve the flow chart, the process includes:

[0080] S501. The terminal is in an interactive state. Within a specified time, there is a functional operation behavior for the terminal, and the terminal can respond to this type of state, such as IM communication, ...

Abstract

The invention belongs to the field of mobile communication and particularly relates to a capability query method, a communication terminal and an application server. A function of integrating capability query requests and a function of analyzing response messages subjected to convergence treatment are added to a request terminal, functions of analyzing the capability query requests received from the request terminal and converging capability query response messages of target terminals are added to the application server, the request terminal can acquire capability information of multiple target terminals through one-time capability query requests, and accordingly SIPOPTIONS message sending quantity is decreased, and network flow is reduced. The communication terminal comprises an integration unit and an analyzing unit, wherein the integration unit is used for integrating URI (uniform resource identifier) of multiple target user terminals of to-be-required capability information into one capability query request; and the analyzing unit is used for responding to converged capability queries received by the receiving unit and analyzing capability information of corresponding target terminals.

Description

technical field [0001] The invention belongs to the field of mobile communication, and specifically relates to a capability information request method, a request terminal and an application server. Background technique [0002] The Session Initiation Protocol (SIP) is a part of the Internet Engineering Task Force (IETF) standards process and is used to establish, modify, and terminate multimedia sessions between message users on an IP network. [0003] The IP Multimedia Subsystem (IMS) proposed by the 3rd Generation Partnership Project (3GPP) is a standard system that supports IP multimedia services independent of access technology. IMS is a system based on SIP. Use the SIP call control mechanism to establish, manage and terminate various multimedia services. [0004] In the application of the IMS network, before initiating relevant operations, the calling user usually queries the status of the called user and the supported service capabilities through a capability query re...
