摘要： Embodiments herein relate to a method in a first radio base station (12) for enabling detection of a faulty antenna in a radio communications network. The radio communication network comprises the first radio base station (12) providing radio coverage in a first cell (14), and a second radio base station (13) providing radio coverage in a second cell (15). The first radio base station (12) receives, from at least one user equipment in the first cell (14), a first set of measurement reports over a first period of time. At least some measurement reports are indicating a cell relation between the first cell (14) and the second cell (15). The first radio base station (12) further forms reference statistics of the cell relation between the first cell (14) and the second cell (15) based on the first set of measurement reports. Furthermore, the first radio base station (12) receives, from at least one user equipment in the first cell (14), a second set of measurement reports over a second period of time. The first radio base station (12) then forms current statistics of the cell relation between the first cell (14) and the second cell (15) based on the second set of measurement reports. The first radio base station (12) then compares the current statistics with the reference statistics to enable the detection of a faulty antenna in the first radio base station (12) or the second radio base station (13).

摘要： Methods, user equipment (120) and target base station (130) for supporting update of neighbour 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 neighbour 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. Neighbour cell relations of at least the source base station may be updated based on the mobility report.

摘要： A controlling node (225) for a first cell (227) in a cellular network (200), arranged to receive measurement reports from User Equipments, UEs (230, 255), in the first cell (227) on the signal strength and/or signal quality of transmissions from the controlling nodes of neighboring cells (217), and to maintain a list of neighboring cells based on such measurement reports. The list shows how many of the UEs (230, 255) in the first cell (227) that each of said neighboring cell's (217) controlling node “covers”, i.e. reaches with a signal strength and/or signal quality above a certain level. The controlling node is also arranged to decide to perform blind handover or release with redirect on one of the UEs in the first cell, and to choose one or more of the cells in the list as the target cell or cells for blind handover or release with redirect.
