Embodiment Construction

[0034] The present invention will be described below in connection with an exemplary communication system. While well suited for use with systems such as those using servers and / or databases, the present invention is not limited to use with any particular type of communication system or configuration of system elements.

[0035] The main controller 110 and the standby controller 120 in this application may be two independent entities / modules, and such terms are only used to distinguish one entity / module from the other, for example, the main The controller of the server and the controller of the backup server, for example, may include multiple controllers in one server or gateway, which are respectively the master controller and the backup controller 120 . The exemplary systems and methods of the present invention will also be described in conjunction with software, modules and associated hardware. However, to avoid unnecessarily obscuring the present invention, the following ...

Abstract

The invention provides a SIP server backup method, a backup recovery method and a system for solving the problem that the real-time hot backup of the SIP server is not always reliable. Wherein a kind of backup method of SIP server comprises, runs SIP protocol stack and handles SIP calling in the master controller, runs SIP protocol stack but does not start transport layer protocol and timer in the standby controller; Standby controller receives the backup of the master controller data, performing hot backup on the received backup data, and correspondingly updating the backup data to the disk. The above solution can smoothly connect the established SIP call when the hot backup fails, and avoid stalemate of the client.

Description

technical field [0001] The invention relates to communication technology / computer technology, in particular to a backup method of a SIP server. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is an application layer signaling protocol proposed by IETF (Interne Engineering Task Force) to implement IP call control. It is widely used and is the core protocol of NGN, IMS, VOLTE, broadband trunking, SIP is used in video surveillance systems, IP phones, proxy servers, VoIP gateways, media servers, and application servers. [0003] Many companies and organizations have developed their own SIP protocol stacks, and some open source protocol stacks have also emerged, such as oSIP, openSIPS, etc. The development of SIP applications has also put forward higher requirements for the high availability of SIP systems. [0004] The SIP system consists of a server and a client. When the SIP server fails (such as power outage, core failure), the se...
