Abstract:
Disclosed in embodiments of the present disclosure are a base station handover method, an apparatus and a base station, related to the technical field of communications. The method comprises: receiving via an S1 interface a Handover Request message sent by a mobility management entity (MME) to which a present device is connected, the Handover Request message carrying indicator information establishing a UAV data radio bearer (DRB); sending a Handover Request Acknowledge message to the MME via the S1 interface, so as to cause the MME to send a Handover Command message to a source base station of the UAV; after receiving a random access request sent by the UAV, establishing a signaling radio bearer (SRB) for the UAV and, on the basis of the indicator information, establishing a DRB for the UAV. By means of the present disclosure, base station handover may be implemented when using a cellular network.
