Problems solved by technology

[0003] The current broadband call platform is based on the call realized by the local server. When the local server AS crashes or disconnects, all session information will be lost. The existing technology has no good solution to this, and it can only be used as a call loss Processing, which affects the operator's subsequent call statistics, bill statistics, etc.

Abstract

Disclosed are a method and system for implementing call saving and recovery. The method comprises: after a calling terminal and a called terminal establish a call, an application server saving session information in a cloud; and when the application server has a fault, a pre-set hosted server of the application server acquiring the session information from the cloud to conduct corresponding service processing. By means of the present invention, at least one hosted server is provided to each application server, the session information about the application server is saved in the cloud, and when the AS has a fault, the most idle hosted server is selected to restore a session, so that the subsequent flow operates normally, thereby effectively reducing the problem of call loss caused by the shutdown or link interruption of the AS, and greatly improving the user experience.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for realizing call saving and restoring. Background technique [0002] The broadband call platform is an application server (Application Server, AS) based on the Session Initialization Protocol (Session Initialization Protocol, SIP), and the SIP protocol realizes the input and output interfaces. [0003] The current broadband call platform is based on the call realized by the local server. When the local server AS crashes or disconnects, all session information will be lost. The existing technology has no good solution to this, and it can only be used as a call loss processing, thus affecting the operator's subsequent call statistics, bill statistics, and so on. Contents of the invention [0004] In view of the above analysis, the present invention aims to provide a method and system for realizing call preservation and restoration, so as to solve the ...
