Embodiment 1

[0049] In order to realize the IMS capability query request, this embodiment will give a solution, the typical network architecture of the system is as follows image 3 shown. In this network architecture diagram, an AS is deployed to process SIP OPTIONS messages on the basis of a traditional IMS network. In this embodiment, the calling user is the capability query requesting 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, the following steps are included: S301, the calling user A initiates a SIP OPTIONS capability query request for multiple target users to the IMS Core, that is, the target user B and the target user C, and the message sample is similar to the following (non-key header fields are omitted ):

Embodiment 2

[0069] In order to further reduce the message flow of the target client network, a storage unit is set in the AS. The AS may temporarily save the queried user capability information to the storage unit. During the validity period of the information, for the capability query request of the target user, if the storage unit stores the capability information of the target terminal, the stored capability information can be directly used without sending a capability query request to the target terminal; the expired capability information in the cache will be used by The AS is deleted from the storage unit, and when there is a corresponding target capability query request next time, it is acquired from the target terminal again 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. Process such as Figure 5 As shown, it specifically includes the following process:

[0070] S401. ...

Embodiment 3

[0079] For user terminals, when the terminal is running in a non-interactive state, such as: standby, watching videos, 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, within a specified time, the terminal has functions Operational behavior, and the status to which the terminal can respond. The user uses the request terminal to perform IM communication, video chat, file transfer or voice call. For example: during IM communication, video chat, file transfer, and voice call, the capability query request function is activated. In this embodiment, the target user is the target terminal. Figure 6 Flowchart for realization, the process includes:

[0080]S501. The terminal is in an interactive state, and 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, video chat, fil...

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...
