Abstract

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.

Description

technical field [0001] The invention relates to a location registration method, a location registration system, a mobile communication terminal, a device for establishing a location registration area and a program for establishing a location registration area. More specifically, it relates to establishing a location registration area (also called a location area) of a mobile communication terminal in a mobile communication system. Background technique [0002] In a conventional mobile communication system, the locations of mobile communication terminals not in communication are managed in units of location registration areas constituted by several cells. In a conventional mobile communication system, a location registration area is fixedly set in advance in the network, and the location registration area is unified and standard for all terminals. [0003] Generally, a change of location registration area is triggered by a non-communicating mobile communication terminal exit...

Problems solved by technology

Then, in the method of the above-mentioned publication, when the mobile communication terminal calculates the optimum location registration area, it must obtain the scale information related to the peripheral cells, so there is a problem related to its traffic
