Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] figure 1 It is a schematic diagram of the active / standby module redundancy backup involved in the VOIP voice service active / standby module synchronization and real-time switching method of the present invention, wherein the main control module is mainly responsible for the relevant configuration of the signaling gateway; the client module is the abstract entity of the client device ; The active module is responsible for signaling processing and completes the call establishment process; the standby module is responsible for backing up the configuration data and service data of the active module. Such as figure 1 As shown, the main control module is responsible for delivering configuration information, and it only communicates with the current main module; the user terminal module is responsible for processing terminal information, such as picking up an...

Abstract

The invention discloses a method for synchronous and real-time reversion for VOIP voice service primary and standby modules, relating to a seamless switch for a primary module and a standby module ofa signaling gateway. After powering up, the standby module establishes communication with the primary module to inform existence of the primary module; the primary module sends configuration information to the standby module; the standby module initiates confirmation to the primary module; the primary module synchronizes service information to the standby module; after synchronization is finished,the primary module marks up a synchronous finish marker at the same time; power-on synchronization of the standby module is finished, and real-time data synchronization is started. In a phase of real-time synchronization, the standby module modifies a self state after analysis according to a communication content to achieve a state of synchronization with the primary module. The method for synchronous and real-time reversion can synchronize data of the primary module and the standby module in real time, have simple switch process, realize the seamless switch of the primary module and the standby module and be suitable for two protocols of MEGACO and MGCP, wherein a new primary module after switch can immediately and accurately treat voice service.

Description

technical field [0001] The invention relates to the seamless switchover of the active and standby modules of the signaling gateway, in particular to a method for synchronizing and real-time switching of the active and standby modules of the VOIP voice service. Background technique [0002] VoIP technology, which transmits calls through the Internet, is one of the most economical telephony technologies in the world. Although there are some serious limitations, due to its low cost and the advantages of providing multiple service functions of voice, data and video at the same time, it has been favored by the communication industry and gradually promoted. [0003] With the more and more widespread use of VoIP technology, people pay more attention to the reliability, performance and security of VoIP networks. For the VoIP network, its reliability involves many aspects, including the software and hardware design of the product itself, the overall structure, the operating system, ...
