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.

Telecommunications network

Systems and methods for operating a cellular telecommunications network. If determining that a first cell of a base station is about to reboot, performing a handover of one or more User Equipments from that cell to a second cell. After the reboot, the user equipment may be handed back to the rebooted cell. If both cells are to reboot, a determination is made to identify which cell's reboot operation is to be prioritized, a handover of the user equipment attached to the prioritized cell to the other cell is made, the prioritized cell is rebooted, all the user equipments are handed over from the non-prioritized cell to the (now rebooted) prioritized cell, the non-prioritized cell is rebooted and the user equipment that was initially attached to the non-prioritized cell is handed over from the prioritized cell back to the now rebooted non-prioritized cell.

Base station report

This disclosure provides a network node, and a method of operating the network node, having one or more communications interfaces connectable to a first communications network and to a second communications network, the method including the network node accessing a service using the first communications network; analyzing data relating to the first communications network to identify a plurality of fault-indicative events; determining a rate of the plurality of fault-indicative events per unit time; and the network node accessing the service using the second communications network in response to a first trigger, wherein the first trigger is based on the rate of the plurality of fault-indicative events per unit time.

Method of operating a network node

There is provided a method, and a network node for implementing the method, in a cellular telecommunications network. The cellular telecommunications network includes a first and second base station, the first base station having a first interface for communicating with a first cellular core networking node and a second interface for wirelessly communicating with the second base station, the second base station being mobile and having a first interface for wirelessly communicating with the first base station and a second interface for communicating with a User Equipment (UE), wherein the UE's user traffic is transmitted between the first cellular core networking node and the UE via the first and second base stations.

Cellular telecommunications network

A method of operating a cellular telecommunications network having a plurality of base stations, wherein each base station of the plurality of base stations has an operational parameter being one of a set of values, wherein the set includes k values, the method including defining a first graph comprising a first plurality of nodes and a first plurality of edges, wherein a node of the first plurality of nodes represents a first base station of the plurality of base stations, and an edge of the first plurality of edges represents a first neighboring relationship between two base stations of the plurality of base stations, wherein each edge of the first plurality of edges has an associated first weight value; partitioning the first graph into k sub-first graphs, each having a first subset of the plurality of nodes and a first subset of the plurality of edges, such as to minimize a first sum value of the first weight values of the first subset of the plurality of edges in all k sub-first graphs; calculating a first conflict value for the k sub-first graphs based on the first sum value; determining whether to initiate a change relating to the operating parameter to one or more base stations in the plurality of base stations based on the first conflict value.

This disclosure provides a method of calculating a distance between a first and second base station in a cellular communications network, and a base station for performing said method, the method including a first base station periodically measuring a power of received signals from a second base station; the first base station identifying a first and second most frequent power of received signals in the periodic measurements; and the first base station determining a distance to a second base station based on the identified first and second most frequent power.

The disclosure provides a method and small cell for allocating a Resource Block (RB) to a transmission between the small cell and a User Equipment (UE) the method comprising generating a value using a quasi-random, low-discrepancy, number generator, associating the value with a RB and allocating the RB to a transmission between the small cell and the UE.
