Document Type and Number:
Japanese Patent JP2545466
Kind Code:
B2
Abstract:
Each of the position registration areas (A,B,C) in mobile radio communication includes a number of base station service areas (ai, bi, ci). Since these areas overlap each other, each base station service area (eg, b23, c23) belongs to a number of position registration areas (B,C). Each of the base stations (b23,c23) transmits all the position registration area codes (B,C). An area code, eg, code (B), is selected so that the position of the mobile unit is located at the centre of the area selected. After registering the area code (B), the mobile unit starts communication. Even when the mobile unit moves beyond the boundary of the position registration area during the communication, updating of the area code is not made within the area of the registered area (B). When it moves outside the area (B), the code is updated, that is, the position of the mobile unit is registered so that this position is in the centre of the area. @(43pp dwg.No.11/14)@.
