Abstract:
1. A cellular telecommunications network, comprising: a radio access network comprising a plurality of geographically distributed cells, each served by a base station; and a core network for providing cellular telecommunications network functions to devices registered therewith over a cellular telecommunications network bearer, wherein the devices provide to the radio access network an indicator of the identity of the cell occupied thereby, respective groups of said cells are allocated to respective location regions by the core network, and the core network maintaining a database of the location region occupied by each device, wherein the cellular communications network is adapted to provide core network cellular telecommunications network functions to devices registered therewith over a non-cellular telecommunications network bearer via another access network comprising a plurality of geographically distributed access points, each served by an access controller, and wherein, when a device switches from the radio access network to the other access network, the access controller of the other access network allocates a reserved cell identity indicator to the device, the reserved cell identity indicator being recognized by a switching center that routes communications received from the device as indicating no location updating is required for the device.
