1. A location registration apparatus comprising:
- a presence area storage unit for storing a presence area information indicating a presence area of a portable communication terminal;
a traveling schedule storage unit for storing a scheduled path information indicating a scheduled path of a moving object and a scheduled time information indicating a scheduled time of the movement of the moving object; and
a control unit for, when the portable communication terminal is moving with the moving object, changing the presence area information of the portable communication terminal stored in the presence area storage unit based on the current time, the scheduled path information, and the scheduled time information stored in the traveling schedule storage unit,wherein the control unit receives, from a moving object communication apparatus installed in the moving object, an identification information of a portable communication terminal moving with the moving object, and specifies the portable communication terminal moving with the moving object based on the identification information,wherein the scheduled path information indicates one or more pass areas through which the moving object passes, and the scheduled time information indicates the time for which the moving object is located in each of the pass areas,wherein, while the portable communication terminal is moving with the moving object, the control unit specifies the pass area within which the portable communication terminal is to be located based on the current time, the scheduled path information, and the scheduled time information, and changes the presence area information of the portable communication terminal to the one corresponding to the specified pass area,wherein the pass area is a base station area each formed by a base station,wherein the traveling schedule storage unit stores an auxiliary path information indicating a more extensive area than the pass area indicated by the scheduled path information; and
wherein, when the moving object is not moving on schedule, the control unit changes the presence area information on the portable communication terminal moving with the moving object to a presence area information according to the location of the moving object based on the auxiliary path information and the scheduled time information.

Abstract
The presence area information of the moving portable communication terminals accompanied by a moving object is changed according to the scheduled path of the moving object and the scheduled time in the movement of the moving object by using a presence area unit which stores the presence area information indicating the presence area of each portable communication terminal and a moving schedule storage unit which stores the scheduled path information indicating the scheduled path of the moving object (a train, etc.) accompanied by at least one portable communication terminal and the scheduled time information indicating the scheduled time of the movement of the moving object.
