Problems solved by technology

However, the scalability of the private protocol is not strong, and it is often associated with the specific data to be backed up
When new backup requirements are added, it is not a general method to modify the private protocol accordingly

Embodiment Construction

[0043] Data backup between network devices generally does not need to back up call state-related data (call state changes very frequently and the amount of data is large, and only real-time backup is performed between the main and standby boards inside the device), but for the user's registration status on the network device Data, subscription status data and other important data with small data volume and infrequent changes are backed up in real time.

[0044] For the SIP registration process, please refer to Chapter 10 "Registrations" of RFC3261. For the basic process of SIP subscription, please refer to RFC3265. Based on the architecture of RFC3265, the specific event subscription mechanism is defined by other RFCs. For example, RFC3680 (A SIP Event Package for Registrations) defines a subscription and notification mechanism for registration status events. Through this mechanism, users can subscribe to their registration status with network devices. When the user's regis...

Abstract

The invention discloses method for backing up SIP application system, server of using the method, and SIP application system. The SIP application system includes client ends of network connected user agent, server of user agent, and stand by server of user agent. The method includes steps: based on first request message sent from client end of user agent to server of user agent to generate second request message, the said first and second request messages include state data; sending the second request message to stand by server of user agent; after receiving the second request message, the stand by server of user agent creates status data. Using message in SIP to accomplish backing up related status data, the method does not need relevant network equipment to support private protocol dedicated design for backing up purpose. Features are: high generality and expansibility.

Description

technical field [0001] The invention relates to a network-level backup method of a session initiation protocol (SIP) application system, equipment using the method, and the SIP application system. Background technique [0002] In order to meet the requirement of 99.999% reliability of telecommunication services, usually each network device providing telecommunication services has a corresponding reliability mechanism inside. For example, a network device is usually composed of multiple processing boards, and the processing boards are configured in a master-standby relationship. Under normal circumstances, services are provided by the master working board. When the main working board fails, the corresponding standby working board becomes the main one to take over the work of the faulty board, ensuring the continuity of service provision. [0003] In addition to the reliability mechanism in the equipment, operators also care about the reliability of the network. A network de...
