Conversation inceptive protocol gateway master-slave conversion system and method

Abstract

The invention discloses a main and a standby switching system of a session initiation protocol gateway and a corresponding method, which relates to the session initiation protocol gateway equipment in the network communication field, in particular to the main and the standby switching system and the accessible realization methods. The system comprises a mainboard (10) and a standby board (20) which respectively comprise a main network module and a standby network module (11,21), a main SIP protocol module and a standby SIP protocol module (12, 22), a main control module and a standby control module (13,23), and a main HA module and a standby HA module (14,24). Between the main board and the standby board (10,20), a card interface is used for achieving the physical link connectivity in the system, the main board and the standby board (10,20) has an independent IP address and an physical address and achieves the logic link connectivity through socket communication. The invention is applicable to the software synchronization of the gateway main and standby switching systems based on the SIP and also applicable to the software synchronization of the gateway main and standby switching systems based on the other non-SIP.

Description

technical field [0001] The invention relates to a session initiation protocol (SIP) gateway device in the field of network communication, in particular to an active-standby switching system and a method for realizing high availability thereof. Background technique [0002] With the further development of Softswitch and IP Multimedia Subsystem (IMS), the entire Softswitch and IMS have transitioned to the era with SIP as the core. In addition to the planned daily maintenance of large-scale deployment of SIP gateway equipment, it should try to eliminate the long-term downtime or temporary interruption of services caused by sudden hardware failures. Therefore, in order to guarantee 99.999% high reliability of the system, it is impossible to meet the requirements only by improving the reliability of the components. Only the key equipment of the system should be backed up. When these equipment fails, their work can be quickly and completely switched to the backup equipment. Make ...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art, and to provide a SIP gateway active-standby switchover system and method thereof; specifically, the present invention is aimed at independent event backup or independent state backup mode technology Insufficient, unreliable hot swap, low efficiency of state backup, etc., make full use of the respective advantages of event backup and state backup, and use state backup and event backup at the same time. The main board provides a clock signal mechanism to the standby board to ensure State synchronization, providing a system and method for realizing active / standby switchover of single boards for SIP gateways, realizing stable, reliable and efficient redundant backup and hot swapping of single boards
