RADIO-RESOURCE MANAGEMENT SYSTEM AND METHOD THEREOF, AND MANAGEMENT APPARATUS, BASE STATION AND TERMINAL TO BE EMPLOYED FOR IT

摘要

Terminals and base stations belonging to service areas 100 to 102 of plural radio operators periodically measure a radio-link quality and an availability ratio of a radio link to notify them to a radio-resource management server 40. The server 40 alters a frequency of the base station, and a transmitted-power quantity of the base station and the terminal based on these measured results to improve the radio-link quality, and reduces interference with a neighboring radio system. When a load is concentrated on a network of a specific radio operator, an instruction of handover is given to the terminal from the server 40 to realize a load distribution within the radio operator, and between the radio operators. When the server 40 detects excessive radio interference between the radio operators, it notifies occurrence of a fault, an interference quantity, a quantity of the transmitted power that the base station should attenuate, and the frequency that the base station should alter to the above radio operator that becomes an interference source.

主权项

1. A radio base station in a wireless network system including a radio-resource management apparatus for managing a radio resource, and radio base stations belonging to a plurality of respective different radio operators, said radio base station comprising:
means for measuring a quality of a radio link and notifying radio-link quality information that is this measured result to said radio-resource management apparatus; and means for, in reply to alteration-control notification of a frequency based on said measured result from said radio-resource management apparatus, taking alteration control of a service frequency on the basis of information relating to other base stations belonging to different operators that the frequency used be said radio base station.
