Abstract

"PROCESSOS PARA REDUZIR E MINIMIZAR INTERFERêNCIA DE CO-CANAL EM UM SISTEMA DE TELECOMUNICAçãO CELULAR" Um processo de reduzir interferência de co-canal em um sistema de telecomunicação celular tendo uma célula de serviço congestionada, uma pluralidade de células vizinhas controladas por um centro de comutação móvel (MSC), e uma estação móvel de acesso tentando acessar o sistema celular na célula de serviço. O MSC busca (16) informação de intensidade de sinal de estações móveis situadas no canal de controle digital (DCCH) da célula de serviço. A informação de intensidade de sinal inclui intensidade de sinal recebidas nas estações móveis situadas da célula de serviço e das células vizinhas. O MSC então busca (27) informação de intensidade de sinal de estações móveis ocupadas envolvidas em chamadas em andamento na célula de serviço. Para cada estação móvel ocupada e situada, a intensidade de sinal de ligação inferior esperada de cada célula vizinha é subtraída da intensidade de sinal de ligação inferior máxima da célula de serviço (28). A combinação de estação móvel/célula vizinha com menor diferença numérica causa a menor interfência de co-canal quando a estação móvel identificada é movida para a célula vizinha identificada. Se a estação móvel identificada é a estação de acesso (34), o MSC redireciona a estação móvel de acesso para acessar o sistema celular na célula vizinha identificada. Se a estação móvel identificada é uma estação móvel ocupada envolvida em uma chamada, o MSC força um transferência de controle da estação móvel identificada para a célula vizinha identificada.
