Problems solved by technology

[0007] (1) The called network where the called user is located cannot control the implementation of the callback service
[0008] Since only the calling network where the calling user is located is selected to implement the callback services such as CCBS and CCNR, the called network where the called user is located cannot control the implementation process of the callback service;
[0009] (2) The application scenarios of the callback service are limited
[0010] In the process of implementing the callback service, it is usually implemented based on the information of the called user. However, since the calling network can only obtain limited information about the called user, the implementation of the callback service is also limited. The callback service can only be realized when the call is busy or there is no answer, and when the called user is turned off, the network is unreachable, or the user restricts incoming calls due to roaming, the calling network cannot obtain the called user in the corresponding situation. information, making it impossible to realize the callback service;

Embodiment Construction

[0020] The embodiment of the present invention provides a callback service implementation scheme for controlling and managing the call-back service in the called network where the called user is located, so that the call-back service can And or be triggered in any situation such as active restriction of incoming calls due to roaming, etc., thereby expanding the scope of application of the callback service.

[0021] In the embodiment of the present invention, the corresponding processing process for implementing the callback service may include: first, after the called network where the called user is located receives the call initiated by the calling user, if the call with the called user cannot be connected, communication, after determining that the call-back activation condition is satisfied according to the callback service trigger policy, the call-back service is started; after that, after the called network determines that the call-back activation condition is met accordin...

Abstract

The invention relates to a method and a device for achieving callback service. The method mainly comprises the following steps: after calling initiated by a calling subscriber is received by a called network where a called subscriber is positioned, if communication between the calling subscriber and the called subscribers can not be connected, starting the callback service after a coincident callback starting condition is determined according to a callback service trigger strategy; and then activating the callback service after a coincident callback activating condition is determined according to the callback service trigger strategy by the called network, so as to establish the communication between the calling subscriber and the called subscriber. Therefore, the implementation process of the callback service can be controlled by a device in the called network of the called subscriber in the embodiment of the invention, thereby more easily obtaining more complete information of the called subscriber, and further greatly increasing the applicable scene of the corresponding callback service.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a technology for realizing a callback service. Background technique [0002] With the development of packet switching technology, the traditional telecommunication network based on circuit switching is gradually developing towards the broadband telecommunication network based on packet switching. [0003] In a packet-switched broadband telecommunications network, in addition to providing call services to users, the network can also provide supplementary service services during the call service process. The corresponding supplementary service services include CCBS (call back if busy) or CCNR (no response) call-back service) and other call-back services; for example, in NGN (next generation network), SIP (Session Initiation Protocol) terminal users can be provided with corresponding call service and supplementary service. [0004] In the above supplementary service, ...
