MOBILE OBJECT SEARCH SYSTEM AND MOBILE OBJECT SEARCH METHOD FOR MOBILE SERVICE

摘要

The location of a mobile object can be specified which lies within a radio zone range to which the range of only one base station corresponds, and a mobile object search method therefor. The mobile object search system includes a database for which is provided a mobile object tracing indication to enable the continuous monitoring of the location of a mobile object which has issued a call when a request for location information concerning the mobile object is transmitted to a switchboard in a mobile service system; mobile object tracing means for registering a mobile object display in the data base; and mobile object location monitoring means for repeatedly monitoring the location of the mobile object, and for using a notification of a change in the location of the mobile object by a minimum control area unit which the mobile object communication network recognizes. The minimum control area unit is a radio zone for one base station.
