MOBILE COMMUNICATION SYSTEM, MOVEMENT PREDICTION DEVICE AND PAGING AREA DETERMINATION METHOD

摘要

In related technologies, when a paging request is made immediately after location registration, a larger paging area than necessary is determined. The technologies have also a problem in that a location registration area and a paging area are not determined in an appropriate manner to sufficiently deal with change in the moving characteristic of a mobile station. A mobile communication system (100) according to the present invention comprises: a movement prediction device (40) which predicts a moving state of a mobile station and, on the basis of the prediction result, creates a base station list consisting of base stations each corresponding to a cell having a high possibility of the mobile station's existence within it; and a movement management device (30) which determines a paging area on the basis of the base station list created by the movement prediction device. There, the movement prediction device is configured such that it calculates an estimated location at a predetermined time and a predicted location at a time later than the predetermined time after a movement, and using the estimated location and the predicted location, creates the base station list, assuming that a possibility of the mobile station's existence is higher for cells in the vicinities of the path from the estimated location to the predicted location than for cells in other areas.
