A method for implementing small cell awakening, comprising: receiving, by an access network element device, information, which is reported by User Equipment, of one or more small cells entering dormancy, wherein the information of the one or more small cells entering dormancy comprises at least one of: current datarate information of the UE, cell types of the small cells, information of supporting modes of the small cells, and broadcast Public Land Mobile Networks (PLMNs) information of the small cells; determining, by the access network element device, a target small cell required to be awakened according to the information, which is reported by the UE, of the one or more small cells entering dormancy; and notifying, by the access network element device through an interface message between access network element devices, an access network element device corresponding to the target small cell to awaken the target small cell; wherein the determining, by the access network element device, a target small cell required to be awakened according to the information comprises at least one of: selecting, by the access network element device, a frequency point to awaken a target cell according to the current datarate information of the UE to determine the target small cell required to be awakened; matching, by the access network element device, the UE capability according to the information of supporting modes of the small cells to determine the target small cell required to be awakened; and matching, by the access network element device, the broadcast PLMNs information with a serving PLMN allowed to be accessed by the UE and equivalent PLMNs information, and then selecting a target small cell supporting user access under a network sharing environment to determine the target small cell required to be awakened. current datarate information of the UE, cell types of the small cells, information of supporting modes of the small cells, and broadcast Public Land Mobile Networks (PLMNs) information of the small cells; determining, by the access network element device, a target small cell required to be awakened according to the information, which is reported by the UE, of the one or more small cells entering dormancy; and notifying, by the access network element device through an interface message between access network element devices, an access network element device corresponding to the target small cell to awaken the target small cell; wherein the determining, by the access network element device, a target small cell required to be awakened according to the information comprises at least one of: selecting, by the access network element device, a frequency point to awaken a target cell according to the current datarate information of the UE to determine the target small cell required to be awakened; matching, by the access network element device, the UE capability according to the information of supporting modes of the small cells to determine the target small cell required to be awakened; and matching, by the access network element device, the broadcast PLMNs information with a serving PLMN allowed to be accessed by the UE and equivalent PLMNs information, and then selecting a target small cell supporting user access under a network sharing environment to determine the target small cell required to be awakened. selecting, by the access network element device, a frequency point to awaken a target cell according to the current datarate information of the UE to determine the target small cell required to be awakened; matching, by the access network element device, the UE capability according to the information of supporting modes of the small cells to determine the target small cell required to be awakened; and matching, by the access network element device, the broadcast PLMNs information with a serving PLMN allowed to be accessed by the UE and equivalent PLMNs information, and then selecting a target small cell supporting user access under a network sharing environment to determine the target small cell required to be awakened.
