Abstract

<B>MéTODO DE CONTROLE ADAPTATIVO GERENCIAL DE CARGA PARA ESTAçãO DE BASE EM SISTEMA CELULAR DE COMUNICAçãO SEM FIO CDMA<D> A carga de tráfego de célula em uma estação de base em um sistema celular de comunicação sem fio de acesso múltiplo por divisão de código (CDMA) é regulada para manter um nível desejado de qualidade de serviço para estações de assinante servidas no momento e a serem servidas pela estação de base. Um sinal-piloto é transmitido da estação de base para permitir que uma estação de assinante adquira um código de operação da estação de base, e uma área de cobertura do sinal-piloto é mantida substancialmente constante para definir um limite de sinal-piloto com relação à estação de base. Um sinal de rádiochamada é transmitido da estação de base para permitir que um assinante que adquire o sinal-piloto obtenha uma atribuição de canal de tráfego da estação de base, e uma condição que representa a carga de tráfego na estação de base é monitorada. Um limite de cobertura do sinal de radiochamada é mudado dentro do limite de sinal-piloto, mediante (a) contração do limite do sinal de radiochamada no sentido contrário ao limite de sinal-piloto quando a carga de tráfego da estação de base estiver aumentando, e (b) expansão do limite do sinal de radiochamada em direção ao limite do sinal-piloto quando a carga de tráfego da estação de base estiver diminuindo.<B> ADAPTIVE MANAGEMENT CHARGE CONTROL CHARGE FOR BASE STATION IN A CDMA WIRELESS COMMUNICATION SYSTEM <D> The load of cell traffic at a base station in a wireless multi-access communication system by division of (CDMA) code is regulated to maintain a desired level of quality of service for subscriber stations currently served and to be served by the base station. A pilot signal is transmitted from the base station to allow a subscriber station to acquire an operation code from the base station, and a pilot signal coverage area is kept substantially constant to define a pilot signal limit with respect to to the base station. A radio call signal is transmitted from the base station to allow a subscriber acquiring the pilot signal to obtain a traffic channel assignment from the base station, and a condition that represents the traffic load at the base station is monitored. A radio call coverage limit is changed within the pilot signal limit by (a) contraction of the radio call signal limit in the opposite direction to the pilot signal limit when the base station's traffic load is increasing, and (b) expanding the radio call signal limit towards the pilot signal limit when the base station's traffic load is decreasing.
