A wireless spectrum resource invoking method, comprising: releasing, by a first base station, wireless spectrum resource requirement information, wherein the releasing, by a first base station, wireless spectrum resource requirement information comprises: broadcasting, by the first base station, wireless spectrum resource requirement information on a preconfigured broadcast resource, wherein the preconfigured broadcast resource comprises at least a preconfigured channel resource, preconfigured broadcast timeslot information, and preconfigured code domain information, wherein the wireless spectrum resource requirement information is used to indicate a currently required wireless spectrum resource; receiving, by the first base station, a wireless spectrum resource authorization message in response to the wireless spectrum resource requirement information from a second base station, wherein the receiving, by the first base station, a wireless spectrum resource authorization message sent by a second base station comprises: checking, by the first base station, in real time whether the wireless spectrum resource authorization message from the second base exists on the preconfigured broadcast resource, and when determining that the wireless spectrum resource authorization message from the second base station exists on the preconfigured broadcast resource, receiving the wireless spectrum resource authorization message, wherein the wireless spectrum resource authorization message comprises authorization information about a wireless spectrum resource authorized to be used by the first base station; and using, by the first base station, the wireless spectrum resource authorized by the authorization information; wherein before the using the authorized wireless spectrum resource, the method further comprises: sending, by the first base station, a wireless spectrum resource authorization response message, wherein the wireless spectrum resource authorization response message is used to inform the second base station sending the wireless spectrum resource authorization message that the authorized wireless spectrum resource is already accepted. broadcasting, by the first base station, wireless spectrum resource requirement information on a preconfigured broadcast resource, wherein the preconfigured broadcast resource comprises at least a preconfigured channel resource, preconfigured broadcast timeslot information, and preconfigured code domain information, wherein the wireless spectrum resource requirement information is used to indicate a currently required wireless spectrum resource; receiving, by the first base station, a wireless spectrum resource authorization message in response to the wireless spectrum resource requirement information from a second base station, wherein the receiving, by the first base station, a wireless spectrum resource authorization message sent by a second base station comprises: checking, by the first base station, in real time whether the wireless spectrum resource authorization message from the second base exists on the preconfigured broadcast resource, and when determining that the wireless spectrum resource authorization message from the second base station exists on the preconfigured broadcast resource, receiving the wireless spectrum resource authorization message, wherein the wireless spectrum resource authorization message comprises authorization information about a wireless spectrum resource authorized to be used by the first base station; and using, by the first base station, the wireless spectrum resource authorized by the authorization information; wherein before the using the authorized wireless spectrum resource, the method further comprises: sending, by the first base station, a wireless spectrum resource authorization response message, wherein the wireless spectrum resource authorization response message is used to inform the second base station sending the wireless spectrum resource authorization message that the authorized wireless spectrum resource is already accepted. checking, by the first base station, in real time whether the wireless spectrum resource authorization message from the second base exists on the preconfigured broadcast resource, and when determining that the wireless spectrum resource authorization message from the second base station exists on the preconfigured broadcast resource, receiving the wireless spectrum resource authorization message, wherein the wireless spectrum resource authorization message comprises authorization information about a wireless spectrum resource authorized to be used by the first base station; and using, by the first base station, the wireless spectrum resource authorized by the authorization information; wherein before the using the authorized wireless spectrum resource, the method further comprises: sending, by the first base station, a wireless spectrum resource authorization response message, wherein the wireless spectrum resource authorization response message is used to inform the second base station sending the wireless spectrum resource authorization message that the authorized wireless spectrum resource is already accepted.
