A method and apparatus for controlling a UAV are provided. The method is applied to a base station, and includes: receiving flight path information transmitted by a UAV controller, wherein the flight path information represents a flight path set by the UAV controller for a UAV controlled by the UAV controller; determining the flight path based on the flight path information; and determining a next base station to which the UAV is to move based on the flight path, and performing a handover preparation for the next base station. Therefore, the present disclosure improves the mobility of the UAV and can also reduce the latency of handover between base stations.

A method performed by a source Radio Network Controller (RNC) for handling a relocation of a User Equipment (UE) connection from the source RNC to a target RNC to serve the UE in an ongoing wireless communication is provided. An interface between the source RNC and the target RNC is available. When all radio links in the ongoing wireless communication are controlled by the target RNC and a triggering condition is fulfilled for relocation of the UE connection from the source RNC to the target RNC, the source RNC decides (202) to discontinue to use said interface. Then a core network is used for sending (204) to the target RNC, a triggering of the relocation procedure for relocating the source RNC to the target RNC to serve the UE. A Radio Resource Control (RRC) configuration defined by the target RNC to be used after the relocation to the target RNC is then obtained (205) via the core network. The RRC configuration, defined by the target RNC, is sent (206) to the UE enabling the UE to switch from an RRC configuration defined by the source RNC to the RRC configuration defined by the target RNC.
