MOBILE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To allow a mobile communication system to easily build up a peripheral station information database. SOLUTION: Base stations are installed so that plural radio zones in a mobile communication system are adjacent to or overlapped each other. When a mobile station 1 is resident in a zone of a base station B, the mobile station 1 stores information of the base station B. When the mobile station moves to a radio zone of a base station A, the mobile station reports information of the base station B being a preceding resident zone base station to the base station A. The base station A receiving a report from the mobile station 1 stores the information of the base station B as the own peripheral base station information in the base station A or a main controller. A peripheral station information database is built up and updated in the own station or the main controller based on the information transmitted from the mobile station by repeating the operation as the above.
