Abstract
When a network element (NE) detects a trouble in an operation system (OpS) for operating the NE itself, a representative NE is determined among a plurality of NEs operated by this OpS. The representative NE selects a substitute OpS from other OpSs and transmits a request for operating the plurality of NEs to the substitute OpS. Thereafter, the plurality of NEs come under the operation of the substitute OpS. The substitute OpS operates the plurality of NEs based on the operation request.
Claims27
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.

A backup method 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,
- the method comprising:
- a step of operating each of the operation systems to operate at least one of the plurality of network elements;
- a step of operating the network element to monitor the operation system that operates the network element itself, then, if the operation system operate the plurality of network elements including the network element itself when detecting a trouble in the operation system, and determine a representative network element representative of the plurality of network elements;
- a step of operating the representative network element to select, from among a plurality of other operation systems, a substitute operation system for operating the plurality of network elements as a substitute for the operation system with the trouble detected, and transmit a operation request for operating the plurality of network elements to the selected substitute operation system;
- a step of operating the plurality of network elements, after the operation request has been transmitted, to come under the operation of the substitute operation system;
- and
- a step of operating each of the operation systems, when receiving the operation request, to operate as the substitute operation system the plurality of network elements.

- a plurality of network elements operated by the plurality of operation systems,
- the method comprising steps of:
- operating each of the operation systems operates at least one of the plurality of network elements;
- operating 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
- operating 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.
