Abstract

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.
