Method and system with improved disaster recovery capability

摘要

A recovery scheme where a base station monitors state of interoperation with a primary exchange. When the primary exchange becomes unavailable, active services may be lost, but the base station sends an activation request message to a secondary exchange that has access to base station configuration information of the base station. The secondary exchange uses the base station configuration information to activate the base station, and user terminals in the base station cell may begin to registrate to the system. Recovery capability of communications can be achieved with optimized use of network resources.

1. A method, comprising:
operating in a communications system as an exchange in a signalling connection with a base station; maintaining access to base station configuration information of the base station; maintaining in the exchange one or more base station units, the one or more base station units being either in an active state or in a standby state; receiving a state transition request message from the base station, the state transition corresponding to activation or de-activation of the base station in the exchange; changing the state of the base station in response to the state transition request, wherein in response to the active state of the base station unit for the base station, maintaining, by the exchange, configuration information and state information of the base station and controlling, by the exchange, communication operations between the exchange and the base station, and wherein in response to the standby state of the base station unit for the base station, not recording the state information, and comprising means for initiating a base station configuration for the base station.
