Call control method, device and system

Abstract

The embodiment of the invention provides a call control method, a call control device and a call control system. The method comprises the following steps of: reporting the call capability of a calling party and the call capability of a called party to computer telecommunication integration (CTI) equipment, wherein the call capability comprises audio capability and / or video capability; and operating the call capability of the calling party and the call capability of the called party according to an instruction of operating the call capability of the calling party and the call capability of thecalled party in a message transmitted by the CTI equipment respectively. In the method, the control of a CTI platform over the call is transferred to the control over the call capability by separating / analyzing the audio capability and video capability of the calling party and the called party from a call and reporting the call capability of the calling party and the called party to the CTI platform, and the separation operation or control over the audio capability and video capability of the call is realized according to the control instruction for the call capability in the message transmitted by the CTI platform, so video needs in the future complex video application sites are satisfied, and favorability for further extending services is achieved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a call control method, device and system. Background technique [0002] With the support of the CSTA (Computer Supported Telecommunications Applications) protocol, the CTI (Computer Telecommunication Integration) platform can issue various messages of the CSTA protocol to achieve call control on the exchange side. [0003] However, due to the continuous increase in video service functional requirements, the existing CSTA protocol has been unable to meet the increasing video requirements. [0004] In the process of implementing the present invention, the inventor found that the prior art has at least the following shortcomings: According to the current standard CSTA protocol, the future complex application scenario cannot be solved, that is, the existing CSTA message cannot realize the future video service scenario. A new call control method and device to solve technical problems exi...
