Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 本発明は、強制切断等による通信品質の劣化 を招来することなく、さらに、トラヒックの偏在や時間 的変動に対しても柔軟に対応できかつシステム容量の大 きな移動通信システムを提供することのできる呼受付制 御方法および装置を提供することを目的とする。 【構成】 複数の無線基地局と複数の移動局との間で無 線チャネルを介して通信を行う移動通信システムにおけ る呼受付制御装置であって、新たに呼を受け付けたとき の干渉量を過去のデータに基づいて予測する第1の予測 手段と、この第1の予測手段で予測された干渉量を参照 して、新たに呼を受け付けたときの当該呼に対応する移 動局および当該無線基地局に既に接続されている移動局 の通信品質を予測する第2の予測手段と、この第2の予 測手段で新たに呼を受け付けたときに所定の通信品質を 満たせない移動局が存在することが予測されたときに は、当該新たな呼の受け付けを拒否する拒否手段とを備 えて構成される。 (57) [Summary] [Object] The present invention does not cause deterioration of communication quality due to forced disconnection, and can flexibly cope with uneven distribution of traffic and temporal fluctuation, and has a large system capacity. An object of the present invention is to provide a call admission control method and device capable of providing a communication system. A call admission control device in a mobile communication system for performing communication between a plurality of radio base stations and a plurality of mobile stations via a radio channel, wherein an interference amount when a new call is accepted A first prediction unit that makes a prediction based on the data, and a mobile station and a radio base station corresponding to the call when a new call is received, with reference to the interference amount predicted by the first prediction unit. There may be a second predicting means for predicting the communication quality of a mobile station already connected to the mobile station, and a mobile station that cannot satisfy the predetermined communication quality when a new call is accepted by the second predicting means. When it is predicted, it is configured to include a rejecting unit that rejects acceptance of the new call.
