Dynamic location registration area determination based on frequency of call arrival and mobility of a mobile communications terminal

摘要

One piece of information used in setting up the optimum location registration area is an area of a peripheral cell. However, in the current system, the area of a cell is set up by the predicted number of subscribers in the area, and therefore, depends on the location. For example, the areas of cells are different between a downtown and a suburban area. Therefore, when a mobile communication terminal computes the optimum location registration area, it is necessary to obtain the size information about the peripheral cell, which can cause the problem of traffic.;The mobile communication terminal in a cell signals a plurality of paging point nodes of mobility and traffic characteristic. Then, the plurality of paging point nodes sets up a location registration area of the mobile communication terminal according to the above mentioned information and network information (number of hops, number of base stations, number of cells, area of cell, number of nodes). Thus, the location management of the mobile communication terminal can be efficiently realized, thereby reducing the traffic.
