Background technology
In click to dial (CTD, Click To Dial) business, User logs in CTD WEB interfaces are inputted or selection logic
Caller id subscriber A and logic called number user B, CTD application server are treated by first call logic caller id subscriber A
After logic caller id subscriber A is answered, CTD application servers call logic called number user B, logic called number user again
B rings, treat that logic caller id subscriber A hears ring-back tone, logic called number user's B off-hooks treat logic caller id subscriber A
With logic called number user B calls, i.e., two side's phones that user is desired with call are carried out by speech channel bridge by CTD business
Connect, and realize the calling class service of two sides call.Three-Way Calling refers to after user A and user B calls that user A is kept and user B
Call, while user A calling party C, user's C off-hooks, user A and user C calls, then user A carry out some operations, use
Family A, user B and user C can mutually hear the sound of other side two-by-two.
In traditional call business, user is directly to dial purpose telephone number by terminal (landline telephone, mobile phone etc.)
To realize call, and CTD business, then it is that the telephone number that two-way needs to be conversed is initiated by CTD application servers respectively
Calling.
Traditional CTD business, is widely used, such as WebCall, Web800 belong to CTD in present communication network
Business or its derivative business.User can check the state of current talking by the call operation interface of CTD business, current logical
The state of words includes the telephone number and name, call state of both call sides, wherein, call state includes：It is called terminal ringing, called
Response, Called Onhook, called calling keep medium；In order that call operation interface is more attractive in appearance, it might even be possible to show on interface
Show head portrait that both sides use etc..CTD business can further expand instant message (IM, the Instance for realizing both call sides
Message) business.Fig. 1 and Fig. 2 are the system structure diagram and method flow schematic diagram of traditional CTD business respectively, are such as schemed
Shown in 1 and Fig. 2, traditional CTD business can only first call certain logic calling subscribe, then call certain logic called subscriber, that is,
The single logical subscriber of calling can only be realized by saying, it is impossible to multiple logic incoming calls while realizing logic calling subscribe, i.e., without
Method realizes Three-Way Calling or carries out videoconference.
Traditional three-party calling method mainly has two kinds：One kind is terminal audio mixing mode, and another is network audio mixing mode.

Code, double-talk, user UE-A keeps the call with user UE-B；User UE-A dials user UE-C number, double-talk,
User UE-A presses " meeting " key, and user UE-A, UE-B and UE-C enter tripartite talks state, carried out by user UE-A terminal
Audio mixing.Fig. 4 is the schematic flow sheet of the method for the Three-Way Calling of network audio mixing, as shown in figure 4, user UE-A dials user UE-B
Number, double-talk, user UE-A keeps and user UE-B call；User UE-A dials user UE-C number, both sides
Call；User UE-A carries out some operations, initiates new calling, and request number is tripartite talks service code；Application server (AS,
Application Server) receive and apply for conferencing resource after the request, UE-A is by REFER message respectively by UE-B, UE-C
Call information inform AS, AS respectively adds user UE-A, UE-B and UE-C in meeting, and user UE-A, UE-B and UE-C enter
Enter tripartite talks state, network audio mixing is realized by AS.The realization of traditional three-party calling method needs terminal to support to mix in itself
Sound, final terminal realizes audio mixing, or needs terminal unit contractual three party service, and by network side audio mixing, and network side audio mixing is still
Terminal is needed to support REFER message, to inform the information of the old session of CTD application servers in new session, therefore to end
The performance at end proposes higher requirement, the production cost of terminal is also increased, with certain limitation.
