Abstract
A method for realizing CTD service includes launching CTD calling request of assigned calling number and called number after client end is logged on application server in soft interchange, realizing connection of calling and called numbers and information state information of connecting course to client end by utilizing application server to control soft interchange, displaying received state information in real time by client end through user boundary.
Description
Technical field
The present invention relates to next generation network, and (Next Generation Network NGN), refers to a kind of click to dial (CTD) service implementation method especially.
Background technology
The NGN network presents the trend that grows stronger day by day, and introduces a series of fresh and new business of making us.In the voice service field, NGN by with the combining of Internet, bring the business experience of renewal for the user.Click to dial (CTD, Click To Dial) professional (or as the trunk business, as unified communication service---UniversalCommunication, be called for short UC---one of traffic performance), allow the user to go up and initiate two party call easily by the click mode in client (the embedded control on the special client software or the WEB page etc.).
In the prior art, a lot of CTD business are when considering implementation, usually pay close attention to more in the link that continues that relates between calling and called, and in that to consider aspect the user interface of direct impression for the user less, the user is after initiating the click to dial action, can not experience the progress of calling well, user-friendliness is had a greatly reduced quality, and has weakened professional attraction; Perhaps rely on the user end to server end fully by inquiring about the state (server end is not initiatively notified call status information to client immediately) that obtains to call out, influenced the performance of whole system to a certain extent, and the information that client obtains there is delay.
Summary of the invention
The invention provides a kind of click to dial (CTD) service implementation method that is applied to next generation network, carry out in the process at Click To Dial in order to solve prior art, client is the problem of show Calls state information in real time.
Click to dial provided by the invention (CTD) service implementation method comprises:
A1, client initiate to specify the CTD call request of calling number and called number after soft switch or application server registers;
B1, application server controls soft switch realize caller and called continuing, and with the state information real-time informing client in the handshaking procedure;
C1, client demonstrate the state information of reception in real time by user interface.
According to said method of the present invention,, then the interaction message between client and the application server is transmitted by soft switch if client is registered to soft switch.
According to said method of the present invention, client is initiated the CTD call request by the SIP INFO, and carries client account number and password.
According to said method of the present invention, among the described step B1, application server returns the CTD call by SIP INFO or 200 OK message to client, carries described state information.
Described step B1 comprises:
B11, application server are called out the calling number of appointment, and return the state information of connecting caller to client;
Behind B12, the caller off-hook, application server is called out the called number of appointment again, and returns success to client and to connect caller, connect called state information;
Behind B13, the called off-hook, the state information that application server returns call setup, conversing to client;
Behind B14, caller or the Called Onhook, application server returns the state information of end of calling to client.
According to said method of the present invention, if caller or called no response, application server returns caller or called no response state information to client, and finishes this CTD call flow.
According to said method of the present invention, also comprise the following steps:
Client initiates to disconnect the CTD call request to application server;
Application server is carried out the connection that disconnects between the calling and called to after the client authentication success, and returns to client and to disconnect the CTD call.
Described disconnection CTD call request is by the carrying of SIP INFO; Described disconnection CTD call is by SIP INFO or 200 OK message bearings.
Described this call identification that comprises command code at least in the CTD call request and return to client by application server that disconnects; Described disconnection CTD call comprises command code, this call identification and processing result information at least.
According to said method of the present invention, also comprise the following steps:
Client is initiated the request of inquiry CTD call information to application server;
The CTD that the application server search is relevant with this customer account number calls out, and returns the response of inquiry CTD call information to client, carries Search Results.
The request of described inquiry CTD call information is by the carrying of SIP INFO; Described inquiry CTD call information response is by SIP INFO or 200 OK message bearings.
At least comprise command code and allocation identification in the request of described inquiry CTD call information; At least comprise in the response of described inquiry CTD call information command code, with inquire about the request of CTD call information in identical allocation identification and Query Result information.
Beneficial effect of the present invention is as follows:
(1) the present invention is handed down to client with the various state informations in the CTD calling procedure in real time by application server, and the user interface by client demonstrates the call status information content in real time, has improved the friendly of user interface and the real-time that information transmits.
(2) the present invention adopts the NGN network architecture, makes full use of the powerful information interaction function of soft switch and application server, realizes simple and convenient.
(3) the present invention uses the SIP INFO as client and server, or the bearing mode of information interaction between client, soft switch and the server, is convenient to the signaling expansion.
