Problems solved by technology

[0006] The biggest disadvantage of this trigger method is that if the calling user has already dialed the called user and completed the call during the period of the periodic call attempt
Since the business is only triggered to the Parlay gateway / APP when it is busy, the normal call of the caller and the called party does not trigger the Parlay gateway / APP, so the Parlay gateway / APP does not know that the caller and the called party have completed the call, and it is still periodic Initiate a trial call to the called party, resulting in harassment of the called user and complaints from the user
[0007] Public literature that discusses and solves the above problems has not yet been retrieved, and there are no related solutions

Embodiment Construction

[0040] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0041] On the service group network, the callback service in case of busyness is loaded on the Parlay gateway / APP, and the Parlay gateway uses SIP (Session Initial Protocol, Session Initiation Protocol) to connect with the Soft Switch. In terms of physical architecture, the Parlay gateway and the application server APP Server can usually be co-located on one device, refer to the structure diagram of the application server figure 1 .

[0042] Such as figure 1 As shown, the Parlay gateway / APP is mainly responsible for business logic control. The soft switch realizes the triggering of the service. The interface between the Parlay gateway and the softswitch is SIP signaling. SHLR (Smart Home Location Register) mainly stores the subscription information of service numbers. The interface between the softswitch and SHLR is the introducti...

Abstract

A method for realizing call back in case of busy subscription, registering the user number on the softswitch as the calling detection point "collected information" and the called detection point "called call attempt authentication" or one of them to trigger the open service Access API Gateway / Application Server. When the calling party is called, the open service access API gateway / application server is triggered, and the application server starts the task of periodically trying to call the called party after receiving the message that the called party is busy; After the caller completes the call, the application server checks whether there is a periodic busy call attempt task between the calling party and the called party, and if so, the application server cancels the task. After adopting the present invention, when the caller and the called party complete the normal conversation, the application server cancels the call trial task in time, avoids harassment to the user, and improves user satisfaction.

Description

technical field [0001] The invention relates to the field of telecommunications, in particular to a method for realizing call back in case of busyness. Background technique [0002] In the fixed network, the existing busy call back service refers to: the calling user calls the called user. If the called user is busy, the service platform can prompt the user to make a choice, and automatically re-initiate the call to the specified called user according to the user's choice. User's call. [0003] The existing callback service on busy has the following problems: [0004] At present, the call back service in case of busyness in the market is the calling back service in case of busyness of the calling party. The calling back in case of busyness of the calling party means that the setting of calling back is controlled by the calling party. This process is only applicable to people who need to contact others frequently and hope to be able to contact them conveniently even when th...
