A fault recovery method for an operation maintenance channel, comprising: detecting whether an operation maintenance channel OMCH between a network management terminal and a base station is normal; characterized in that: if the operation maintenance channel OMCH is abnormal: detecting whether the service channel between the base station and the base station controller is normal, wherein the detecting whether the service channel between the base station and the base station controller is normal comprises: controlling the base station controller to periodically send a packet to the base station through the service channel; and determining whether a response message after the base station receives the packet is received within a preset duration; and if the response message is received, determining that the service channel is normal; and, if the service channel is normal, performing the step of controlling a base station controller to deliver a reset instruction to the base station through a service channel bearing service functions; and controlling a base station controller to deliver a reset instruction to the base station through a service channel bearing service functions, so that the base station performs a reset operation after receiving the reset instruction. detecting whether an operation maintenance channel OMCH between a network management terminal and a base station is normal; characterized in that: if the operation maintenance channel OMCH is abnormal: detecting whether the service channel between the base station and the base station controller is normal, wherein the detecting whether the service channel between the base station and the base station controller is normal comprises: controlling the base station controller to periodically send a packet to the base station through the service channel; and determining whether a response message after the base station receives the packet is received within a preset duration; and if the response message is received, determining that the service channel is normal; and, if the service channel is normal, performing the step of controlling a base station controller to deliver a reset instruction to the base station through a service channel bearing service functions; and controlling a base station controller to deliver a reset instruction to the base station through a service channel bearing service functions, so that the base station performs a reset operation after receiving the reset instruction. controlling the base station controller to periodically send a packet to the base station through the service channel; and determining whether a response message after the base station receives the packet is received within a preset duration; and if the response message is received, determining that the service channel is normal; and, if the service channel is normal, performing the step of controlling a base station controller to deliver a reset instruction to the base station through a service channel bearing service functions; and controlling a base station controller to deliver a reset instruction to the base station through a service channel bearing service functions, so that the base station performs a reset operation after receiving the reset instruction.
