Abstract
Methods, user equipment (120) and target base station (130) for supporting update of neighbor cell relations in a cellular communications network (100). The user equipment (120) switches from being served in the source cell (115) by the source base station (110) to instead being served in the target cell (135) by the target base station. The user equipment sends (304, 403), to the target base station (130), in association with the switching, an identifier of the source cell (115) in the cellular communications network (100) and a request for mobility report. The request for mobility report requests the target base station (130) to send a mobility report to the source base station (110) or a management entity (140) thereof. The mobility report reporting that a successful switch has taken place between the source cell (115) and the target cell (135), thereby enabling updating of the neighbor cell relations based on the mobility report. Hence, reporting back of successful cell switching is enabled even when the target base station is unprepared by the source base station about the switching. Neighbor cell relations of at least the source base station may be updated based on the mobili…
