ABSTRACT:
This disclosure concerns systems and methods for location updating in communications networks. In one example, when a device initiates a connection to an access network, by way of which a communications network is adapted to provide core network GSM functions to devices registered therewith over a non-GSM bearer, a core network interrogates the device to obtain, if available, data indicative of the cell occupied thereby, interrogates the core network to obtain, if available, an indicator of the identity of the cell occupied by the device, obtains, if available, data indicative of the location of the access point with which the device communicates, and, in dependence on that location, selects an access controller for communicating with the access point or instructs the device to attempt to connect to the GSM radio access network.
