BSC disaster recovery method, BSC disaster device, BSC disaster system and BSC disaster server

The invention provides a BSC disaster recovery method, a BSC disaster device, a BSC disaster system and a BSC disaster server and aims at solving the problem of BSC disaster recovery. The BSC disaster recovery method includes the following steps. An upgrading order is sent to an MSC, an attribution of a first port of a BSC in a preset range is modified to a preset base station controller pool. Different control orders are set for the BSC in the preset range. When a first BSC of the BSC in the preset range undergoes disaster recovery, a first control order which corresponds to the first BSC is confirmed. Based on the first control order, all base stations under the first BSC are confirmed and the first control order is emitted to a control unit. All the base stations under the first BSC are connected with redundance ports of the preset base station controller pool through the control unit. By means of a method of reusing transmission resources, the control unit is used for massively issuing connection data. Ba
