A method for maintaining a base station, comprising: receiving, by a first base station, an operation and maintenance, OM, command from a network management system, NMS, device via a second channel or a third channel; wherein the second channel comprises a channel between the first base station and a second base station, and a second OM channel between the second base station and the NMS device; and the third channel comprises a channel between the first base station and a core network node, and a third OM channel between the core network node and the NMS device; determining, by the first base station, that a first OM channel between the first base station and the NMS device is in an interrupted state; and implementing, by the first base station according to the OM command, operation and maintenance of the NMS device on the first base station; wherein before receiving the OM command via the second channel or the third channel, the method further comprises: accepting, by the first base station, one of the following active reset conditions pre-configured by the NMS device for the first base station, and performing, by the first base station, an active reset operation in a case that the pre-configured active reset condition is met; wherein the pre-configured active reset condition comprises one of the following: the first OM channel is in an interrupted state, and the channel between the first base station and the second base station is also in an interrupted state; the first OM channel is in an interrupted state, and the channel between the first base station and the core network node is also in an interrupted state; and the first OM channel is in an interrupted state, and both the channel between the first base station and the second base station, and the channel between the first base station and the core network node are in an interrupted state. receiving, by a first base station, an operation and maintenance, OM, command from a network management system, NMS, device via a second channel or a third channel; wherein the second channel comprises a channel between the first base station and a second base station, and a second OM channel between the second base station and the NMS device; and the third channel comprises a channel between the first base station and a core network node, and a third OM channel between the core network node and the NMS device; determining, by the first base station, that a first OM channel between the first base station and the NMS device is in an interrupted state; and implementing, by the first base station according to the OM command, operation and maintenance of the NMS device on the first base station; wherein before receiving the OM command via the second channel or the third channel, the method further comprises: accepting, by the first base station, one of the following active reset conditions pre-configured by the NMS device for the first base station, and performing, by the first base station, an active reset operation in a case that the pre-configured active reset condition is met; wherein the pre-configured active reset condition comprises one of the following: the first OM channel is in an interrupted state, and the channel between the first base station and the second base station is also in an interrupted state; the first OM channel is in an interrupted state, and the channel between the first base station and the core network node is also in an interrupted state; and the first OM channel is in an interrupted state, and both the channel between the first base station and the second base station, and the channel between the first base station and the core network node are in an interrupted state. accepting, by the first base station, one of the following active reset conditions pre-configured by the NMS device for the first base station, and performing, by the first base station, an active reset operation in a case that the pre-configured active reset condition is met; wherein the pre-configured active reset condition comprises one of the following: the first OM channel is in an interrupted state, and the channel between the first base station and the second base station is also in an interrupted state; the first OM channel is in an interrupted state, and the channel between the first base station and the core network node is also in an interrupted state; and the first OM channel is in an interrupted state, and both the channel between the first base station and the second base station, and the channel between the first base station and the core network node are in an interrupted state. the first OM channel is in an interrupted state, and the channel between the first base station and the second base station is also in an interrupted state; the first OM channel is in an interrupted state, and the channel between the first base station and the core network node is also in an interrupted state; and the first OM channel is in an interrupted state, and both the channel between the first base station and the second base station, and the channel between the first base station and the core network node are in an interrupted state.
