摘要： a cellular base station detects that it is about to shut down, either because no mobile terminals are within range (64), or because of a loss of power (66), for example because a user has deliberately switched it off, it first broadcasts a report that is about to shut down (65, 67). This broadcast signal is picked up by the neighbouring cells (44,46) and used to update their neighbour lists, thus avoiding a false alarm which would otherwise be generated by the neighbours and transmitted to a centralized Operation Administration and Maintenance system when the shut-down cell fails to be detected on the next sampling cycle. The neighbours can then retain the shut-down base station in the neighbour list. The cause of the shut-down may be identified in the shut-down report (65, 67), and a self-organising frequency reuse plan adjusted if the base station is shut down altogether (68) (for example because of a loss of power) but remain unchanged if the base station is continuing to operate in receive-only mode (60) because no mobile terminals are within its range. The base station has a standby battery which allows a "grateful" shutdown even if the main power supply is cut off.

摘要： Network addresses which are frequently accessed by user terminals are monitored by a network access point to which the terminals are connected, and the network access point then makes attempts (50) to access the network addresses from time to time and makes reports to a network management system (53) of any such network addresses that fail to respond. This increases the likelihood of detection and reporting of failures of active addresses before the user has need of them.

摘要： In a cellular telecommunications system, outage management is managed in respect of each cell B by a nominated neighbour cell A, the identity of which is recorded in a neighbour list for cell B. If a cell C, D, other than the nominated neighbour, detects a suspected outage in a cell B, the cell detecting the outage identifies the nominated neighbour A from the neighbour list of cell B, and transmits an outage report to the nominated neighbour cell A, which coordinates a handover and outage management process. This avoids multiple detections of the same outage resulting in conflicting attempts to manage the recovery process. Selection of the nominated neighbour of a cell B may be made autonomously by the cell itself or by a centralised processor (2), and may be done in such a way as to support network resilience by avoiding reciprocity between cells, selecting, for a cell B connected to a first backhaul system (4), a nominated neighbour A using a second backhaul system (3), and avoiding the use of cells E having intermittent or transient connections to the network.

摘要： An outage of a cellular base station is detected by a neighbouring base station (2) when a beacon signal previously stored (46) by the neighbour (2) in respect of the base station being monitored is compared (45) with the result of a subsequent search for that signal (44) and found to have deteriorated or ceases to be detected (step 45). If the search identifies such an event (47), the search is repeated at a shorter interval (step 48) and an outage is reported (49, 51) to a management centre (90) if the base station also fails to be detected on subsequent consecutive sampling cycles. This avoids false alarms from reboots and other transitory losses of signal that would be caused by an outage report based on a single loss of signal.
摘要翻译：当由邻居（2）预先存储（46）关于被监视的基站的信标信号时，由邻近基站（2）检测蜂窝基站的中断（2）（45），随后搜索该信号（44）并发现已经恶化或不再被检测（步骤45）。如果搜索识别了这样的事件（47），则如果基站也未能被检测到，则以更短的间隔重复搜索（步骤48），并且向管理中心（90）报告中断（49,51）随后的连续采样周期。这样可以避免因重启导致的错误警报以及基于单一信号丢失的停电报告导致的其他短暂信号损失。
