Abstract
A telecommunications system, apparatus and method is disclosed for optimizing the use of paging channels within the network by dividing location areas (LAs) into sub-location areas (sub-LAs) and providing a more efficient and flexible method of paging mobile subscribers. The amount of usage of the paging channels and the number of location updates performed by a mobile subscriber can be monitored by the network to determine either statistical data or a subscriber category, e.g., heavy-user or light-user, which can be stored within the Subscriber Identity Module (SIM) card within the mobile station (MS). The sub-LA information along with the LA information for the cell that the mobile terminal is in is broadcast and monitored by the SIM card within the MS, which can then perform location updates based upon the category or data. The Mobile Switching Center/Visitor Location Register can also use the data or category for paging purposes, e.g., either page within the entire LA or within only the sub-LA, for more focused paging.
