Abstract: A network node for a wireless telecommunications network, and a method of operating a network node, are disclosed. The wireless telecommunications network includes a first access point having a first transmitter configured to transmit in a first coverage area, and the method can include receiving, from a sensor, data indicative of an object within the first coverage area of the first access point's first transmitter; determining, from the data, that the object is an illegitimate user; and, in response, causing a modification of the first access point so that the object cannot successfully receive a transmission from the first transmitter.

Abstract: A method of operating a wireless telecommunications network includes identifying a signal coverage area of a moving base station, that forms part of a first telecommunications network, to which to allocate a first physical network identifier, determining a second physical network identifier for enabling user equipment to access an access point that serves the identified signal coverage area, wherein the access point is stationary relative to the moving base station and forms part of a second wireless telecommunications network, and associating the first physical network identifier with the second physical network identifier. The method further includes allocating the first physical network identifier to the moving base station to allow user equipment within the signal coverage area to access the moving base station via the first physical network identifier when the moving base station is providing a telecommunications signal in the identified signal coverage area.

Abstract: In a cellular telecommunications system, outage management is managed in respect of each cell B by a nominated neighbor cell A, the identity of which is recorded in a neighbor list for cell B. If a cell C, D, other than the nominated neighbor, detects a suspected outage in a cell B, the cell detecting the outage identifies the nominated neighbor A from the neighbor list of cell B, and transmits an outage report to the nominated neighbor 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 neighbor of a cell B may be made autonomously by the cell itself or by a centralized processor, 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, a nominated neighbor A using a second backhaul system, and avoiding the use of cells E having intermittent or transient connections to the network.
