Problems solved by technology

This method of using database synchronization requires that the voice server must integrate a commercial database, that is to say, the most common voice server supporting the VoIP protocol cannot achieve data synchronization, thus greatly reducing the versatility of the device and limiting the business. The flexibility achieved reduces the networking capability

Embodiment Construction

[0062] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] Analyzing the equipment characteristics of general voice servers and voice terminals shows that in VoIP technology, all voice servers and voice terminals support the VoIP protocol. Therefore, if the inherent VoIP protocol of the voice server and voice terminal can be used to realize the main voice The service switching after server failure recovery and the realization of data synchronization between voice servers can greatly reduce the requirements on the voice server and the voice terminal, and improve the versatility of the voice server and the voice terminal.

[0064] In view of the above characteristics, first of all, the present invention proposes a service switching method after the main voice server fails to recover. The metho...

Abstract

The switching method includes steps: the standby voice server (SVS) detects whether fault of the main voice server (MVS) is recovered; if yes, through triggered message of IP voice (VoIP) protocol, SVS sends information of fault recovery of MVS to voice terminal; voice terminal switches the service to MVS. The invention also discloses method for synchronizing data between voice servers. The method includes steps: through synchronization message in VoIP protocol, first voice server sends self-data needed to synchronize to second voice server; second voice server carries out synchronization for self saved data. Since VoIP protocol is intrinsic protocol for voice server and voice terminal, thus, in the invention, voice server and voice terminal does not need to support other protocol additionally so as to raise versatility of device, increase flexibility to implement service, and enhance capability for constructing network.

Description

Technical field [0001] The present invention relates to network communication technology, in particular to a service switching method and system after a main voice server fails to recover. Background technique [0002] Voice over IP (VoIP) technology is a technology that uses packet switching to transmit voice data in an IP network. In VoIP technology, in order to prevent a voice server from malfunctioning and causing service interruption, a voice server backup method is used to provide services to voice terminals. Figure 1 is a schematic diagram of providing services in a voice server backup manner in the prior art. Figure 2 is a flow chart of implementing voice server backup in the prior art. Referring to Figure 1 and Figure 2, in the prior art, the process of implementing voice server backup includes the following steps: [0003] Step 201: Set up the main voice server and the backup voice server that support the private protocol. [0004] Step 202: Integrate a database on the ...
