A method for performing communication in software-defined networking, wherein the method comprises: receiving, by a base station, a message sent by a UE; determining, by the base station according to a control policy, a matching condition that matches the message, wherein the control policy comprises a matching condition and operation information corresponding to the matching condition; processing, by the base station, the message according to the operation information corresponding to the matching condition that matches the message; and sending, by the base station, the processed message to the network device; characterized in that said processing according to said operation information corresponding to the matching condition that matches the message comprises peeling off a radio link message header of the message and applying the message content, wherein, before the determining, according to a control policy, a matching condition that matches the message, the method further comprises: receiving, by the base station, the control policy sent by a control device, wherein the control policy determines a flow table, wherein each flow entry in the flow table comprises a matching condition and operation information corresponding to the matching condition; wherein the determining a matching condition that matches the message specifically comprises: determining, by the base station according to the flow table, that a matching condition of a first flow entry is the matching condition that matches the message; and the processing the message according to the operation information corresponding to the matching condition that matches the message specifically comprises: processing, by the base station, the message according to operation information of the first flow entry. receiving, by a base station, a message sent by a UE; determining, by the base station according to a control policy, a matching condition that matches the message, wherein the control policy comprises a matching condition and operation information corresponding to the matching condition; processing, by the base station, the message according to the operation information corresponding to the matching condition that matches the message; and sending, by the base station, the processed message to the network device; characterized in that said processing according to said operation information corresponding to the matching condition that matches the message comprises peeling off a radio link message header of the message and applying the message content, wherein, before the determining, according to a control policy, a matching condition that matches the message, the method further comprises: receiving, by the base station, the control policy sent by a control device, wherein the control policy determines a flow table, wherein each flow entry in the flow table comprises a matching condition and operation information corresponding to the matching condition; wherein the determining a matching condition that matches the message specifically comprises: determining, by the base station according to the flow table, that a matching condition of a first flow entry is the matching condition that matches the message; and the processing the message according to the operation information corresponding to the matching condition that matches the message specifically comprises: processing, by the base station, the message according to operation information of the first flow entry. receiving, by the base station, the control policy sent by a control device, wherein the control policy determines a flow table, wherein each flow entry in the flow table comprises a matching condition and operation information corresponding to the matching condition; wherein the determining a matching condition that matches the message specifically comprises: determining, by the base station according to the flow table, that a matching condition of a first flow entry is the matching condition that matches the message; and the processing the message according to the operation information corresponding to the matching condition that matches the message specifically comprises: processing, by the base station, the message according to operation information of the first flow entry. determining, by the base station according to the flow table, that a matching condition of a first flow entry is the matching condition that matches the message; and the processing the message according to the operation information corresponding to the matching condition that matches the message specifically comprises: processing, by the base station, the message according to operation information of the first flow entry.
