Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] Figure 4 It is a flow chart of an inquiry transfer service method according to an embodiment of the present invention, including the following steps:

[0030]Step S10, user A and user B first establish a call;

[0031] Step S20, user B initiates a call transfer request, requesting to be transferred to user C;

[0032] Step S30, the application server of user B intercepts the request, and returns an acceptance response to user B;

[0033] Step S40, the application server of user B first initiates a call invitation to user C, and obtains the media parameter information of user C;

[0034] Step S50, the application server of user B initiates a re-call invitation to user A, provides user C's media parameter information, instructs user A to perform media switching, and obtains user A's media parameter information;

Abstract

The invention provides a method and a device which are used for call forwarding busy service. The method comprises the steps that: a user A and a user B firstly set up a call, when the user B sets up a call with a user C, call forwarding request is initiated to require to transfer the call with the user A to the user C; an application server of the user B intercepts the request and returns to the user B to receive response; the application server of the user B firstly originates call invitation to the user C and obtains medium parameter information of the user C; the application server of the user B originates call invitation to the user A renewedly and provides the medium parameter information of the user C to indicate the user A to carry out medium switching and obtain medium parameter information of the user A; the application server of the user B provides the medium parameter information of the user A for the user C and indicates the user C to set up medium flow connection with the user A; and the application server of the user B indicates the user B to hang up to stop the call originally set up between the user A and the user B.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for implementing blind transfer services in the Next Generation Network (NGN). Background technique [0002] Call transfer (Call Transfer) is a supplementary service in the communication system: when two users (user A and user B) establish a call in the communication system, one of the users (take user B as an example) can request to transfer the current The call is transferred to a third party (user C), that is, the call is established between user A and user C, and the call path between user A and user B is disconnected. A common application scenario for this service is: the secretary of the general manager (user B) first answers all incoming calls (user A), asks the other party what they are coming for, and uses the call transfer service to transfer the calls that the general manager needs to answer personally to the general manager ( User C)...
