Abstract
User equipment is to be handed over from a source cell to a target cell in a radio communication network. The user equipment is assigned dedicated uplink resources in the source cell, and a handover candidate cell is prepared for receiving the user equipment by obtaining information about the assigned dedicated uplink resources in the source cell. A radio base station for the handover candidate cell is listening for user equipment transmissions and determines, when receiving a user equipment transmission, whether the received user equipment transmission can be detected based on information about the assigned dedicated uplink resources in the source cell in order to assess if the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. The radio base station for the handover candidate cell initiates a handover procedure for the user equipment if it is assessed that the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. In this way, handover can be initiated and completed even if the serving radio base station of the source cell cannot receive a handover-triggering measurement report from the UE.
