Abstract: In a mobile network comprising a plurality of base stations and a gateway, a user equipment may perform a handover from a source base station to a target base station. By control signalling, the handover may be notified from the target base station to a control node of the mobile network and then to the gateway so that the gateway may switch to a data path which connects the target base station and the gateway. The notification of the handover may be delayed at the target base station or at the control node, by starting a timer and sending the control signalling for initiating the path switching after expiry of the timer.
