Abstract:
1. A method of building a tracking area list for a user equipment in a network having a plurality of tracking areas and a plurality of user equipments capable of being moved between tracking areas of the network, comprising: maintaining in a computer memory data disclosing a frequency of tracking area management events of user equipments between every pair of tracking areas of the network over a time period, the tracking area management events comprising paging events and tracking area update events; receiving relative cost data of real time costs of a paging event relative to real time costs of a tracking area update event in the network, the real time costs being defined by a network operator, wherein the real time costs comprise an average load required to perform a paging event or a tracking area update event; determining, using a processor, a ratio of paging event to tracking area update event in the network for at least one user equipment; predicting, using a processor, based on the frequency data, the relative cost data, and the ratio data, a number of tracking areas, n, to include in a tracking area list for the at least one user equipment, which number predictively reduces a sum cost of paging events and tracking area update events in the network; and constructing, using a processor, a tracking area list for the at least one user equipment having n tracking areas.
