ABSTRACT:
In a cellular radio network in which mobile stations roam, in addition to location updating of each mobile station with the accuracy of one location area, a so-called temporary subscriber-specific paging area is determined. Each mobile station initiates the determining of the temporary paging area in the subscriber data base of the cellular radio network after being located in a cell for a sufficiently long period. The temporary paging area is smaller than the location area (e.g., one cell and possibly at least one adjacent cell), and thus the paging of a mobile station can be focused on a small area, i.e., the temporary paging area. It is thus unnecessary to page over the entire location area, and paging time can be reduced and capacity of the cellular radio network spared.
