RADIO QUALITY DETERIORATION PREVENTING METHOD FOR CDMA MOBILE RADIO COMMUNICATION SYSTEM, AND CDMA MOBILE RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent the radio quality from deteriorating by continuously monitoring the output information of a mobile device and forcibly stopping the radio communication of faulty mobile device sending an abnormal output automatically or manually by a service engineer if the faulty mobile device is detected. SOLUTION: A base station controller 13 which has received mobile device fault detection alarm signals from base stations 12a to 12n transfers a message to base station maintenance controllers 14a to 14k. The base station maintenance controllers 14a to 14k sends a mobile device fault detection alarm report out to a total maintenance monitor device 19. A base station position information data server 16 retrieves the position of specified base station information and a subscriber characteristic identification information data server 18 retrieves specified subscriber information from a data base and reports it to the total maintenance monitor device 19. After fault information is recorded, the total maintenance monitor device 19 sends a specific MS transmission indication instruction to the base station maintenance controllers 14a to 14k under automatic control or manual control.
