Parameter updating method in a mobile communication system

摘要

To provide a base station apparatus that can automatically update the parameters required for radio communication. A pair of identifier for identifying the self station and radio communication parameter is notified to another base station existing in the neighborhood of the self station, and the path loss value between another base station and a mobile station and the pair of identifier and radio communication parameter for another base station is acquired. The pair of identifier and radio communication parameter reported by the self station is set and updated, based on this acquired information. Since it is updated in consideration of the path loss value reported from the mobile station, the parameter can be updated at higher precision.
