摘要： A cell planning tool capable of determining the correctness of stored parameters regarding a cell site configuration, e.g., regarding the height of an antenna section or the output power. The correctness of the parameters is determined by importing a number of in-situ signal strength-measurements from measuring points located within the coverage area of said cell site and predicting the signal-strength at each of said measuring points, using said stored parameters. Thereafter, the difference between the imported and the corresponding predicted signal-strength is calculated for each measuring point, and a value indicating the correctness of the stored parameters is estimated, based on said calculated signal-strength differences.

摘要： 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 mobility report.

摘要： A domain name associated with a radio network node's operator or maintenance (OM) node is determined based on at least part of a radio node identifier and a radio network operator identifier. The radio network node sends the domain name to a domain name server. In response to sending the constructed domain name, the radio network node receives from the domain server an IP address for the OM node. The radio network node then initiates a connection with the OM node using the IP address. In one non-limiting example embodiment, the part of the radio node identifier is a radio network node vendor identifier.

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.

摘要： In one aspect, the teachings herein provide an enhanced inter-base-station interface and associated processing in which a base station receives a message from a neighboring base station that zero served PLMNs are available in a neighboring cell. In response to receiving that message, the base station removes the neighboring cell from its neighbor list, or otherwise marks the neighboring cell as unavailable, but advantageously does not discard any network performance data accumulated or otherwise generated for that neighboring cell. Correspondingly, should the base station receive a subsequent message indicating that one or more served PLMNs have become available in the neighboring cell, it restores the neighboring cell to its neighbor list and reinstates links or associations, as needed, to the retained network performance data.
摘要翻译：在一个方面，本文的教导提供了增强的基站间接口和相关联的处理，其中基站从相邻基站接收到零服务的PLMN在相邻小区中可用的消息。响应于接收到该消息，基站从其邻居列表中移除相邻小区，或以其他方式将相邻小区标记为不可用，但是有利地不丢弃对该相邻小区累积或以其他方式生成的任何网络性能数据。相应地，如果基站接收到指示一个或多个服务的PLMN在相邻小区中变得可用的后续消息，则其将相邻小区恢复到其邻居列表，并根据需要将链路或关联恢复到所保留的网络性能数据。

摘要： The technology described in this application provides a way for an O&M node or system to configure, monitor, and manage relay nodes efficiently. A base station serves a relay node in a cellular communications system that also includes the O&M node. A relay node O&M data context for the relay node is established in a memory associated with the base station. O&M data pertaining to the relay node is stored in the relay node O&M data context. The information in the relay node O&M data context is different than O&M data pertaining to the base station. The base station performs, on behalf of the relay node, O&M-related communications using the O&M data in the relay node O&M data context.
