Abstract:
A backup system for an operation system in a communications system, comprising:a plurality of operation systems connected to each other via a network; and a plurality of network elements operated by the plurality of operation systems, wherein each of the operation systems operates at least one of the plurality of network elements, each of the network elements monitors the operation system that operates the network element itself and detects failures in this operation system, when the failures are detected, if the failures-detected operation system operates a plurality of network elements, a representative network element is determined among the plurality of network elements under the failures-detected operation system, the representative network element selects a substitute operation system among the other operation systems and transmits an operation request to the substitute operation system, and each of the operation systems, when receiving the operation request, as the substitute operation system, operates the plurality of network elements under the failures-detected operation system.
