Abstract
This disclosure concerns methods and systems for network communications. In one example of such a method, respective groups of cells are first allocated to respective location regions. Next, respective indicators are received from various devices, indicating the identity of the cell occupied by the corresponding device. Additionally, a database is maintained that includes information concerning the location region occupied by each device. In operation, when a device switches from a radio access network to another access network, the other access network receives the indicator of the identity of the cell occupied by the device and, in dependence thereon, selects the location region which the device is deemed to occupy by a core network.
