In a cellular mobile access communications system each mobile terminal registers its location at intervals. From the registration history of each mobile, a probable group of cells within which a mobile terminal may be located is predicted. When a mobile is to be paged, the paging message is transmitted to the predicted cell group. If no response is received from the terminal, the page message is then broadcast to further system cells. This reduces the overall paging load on the system.

[ We claim:] [1.] A method of paging a mobile terminal in a cellular communications system comprising a plurality of cells in each of which mobile terminals currently located therein may be serviced by a respective base station, base station controllers each controlling a respective group of base stations, and a mobile switching centre controlling said base station controllers, wherein the method comprises the steps of;providing at a central store associated with the mobile switching centre a cell location record of each mobile terminal at regular intervals, said record comprising the present cell location and a number of previous cell locations of the mobile terminal;determining from the location record of each said mobile terminal a pattern of movement of that terminal within the mobile system;predicting, from the present cell location in which a mobile terminal to be paged was last recorded and from the pattern of movement for that terminal determined from its recorded present and previous cell locations, a paging zone consisting of a group of cell within which there is a significant probability of finding the mobile terminal;transmitting a first paging message for that terminal to the group of cells comprising said paging zone via the respective base station controller(s) and base station(s) so as to page the mobile terminal in each cell of said paging zone;determining whether the mobile terminal has responded to the first paging message and transmitting at least one repeat paging message for that terminal to further system cells in response to a determination that the mobile terminal has not responded to said first paging message.
