System and realizing method for click-to-dial service

Abstract

The invention provides a realizing method for click-to-dial service, which comprises that: a control client initiates a control command to a click-to-dial application server to initiate the call between a calling user and a called user, and the control command carries a call type; and after receiving the control command, the click-to-dial application server establishes the call between the calling user and the called user, wherein in the call establishing process, the click-to-dial application server informs the calling user and the called user of the call type of the call. The invention alsoprovides a click-to-dial service system. The method and the system maintain the consistency of a medium type in the call process by controlling the port information of the medium type, and improve user experience.

Description

technical field [0001] The present invention relates to in IP Multimedia Subsystem (IMS) network or Soft Switch (SS) network, based on Session Initiation Protocol (Session Initialization Protocol, SIP) AS (Application Server, application server) realizes click-to-dial with video call function A system and method for (Click To Dial, CTD) business. Background technique [0002] like figure 1 As shown, the click-to-dial service means that the user initiates a call between user A and user B through the click-to-dial control client, wherein the control client sends a control command to the click-to-dial application server, and after the click-to-dial application server receives the control command, it passes The IMS / SS network exchanges with user A and user B to establish a call. The initiator of the service may not be the same as the person involved in the service, that is, the control client that initiates the CTD call does not necessarily need to be one of the A and B users ...

AI Technical Summary

Problems solved by technology

In the CTD process with video call function, the control client may initiate an audio call, but because the actual call accepting client is separated from the control client, the calling client does not perceive the type of the call, and needs to select Whether to use audio or video calls, the user experience is poor

In addition, during the call process, the user may choose call hold and release hold, and the process of call hold switching is the process of media switching. In the process of media switching and call release process, there is also the problem of call type selection, that is, the call client Also needs to choose whether to use audio or video calls, which degrades the user experience
