Abstract

"REDE DE COMUNICAçãO MóVEL CELULAR E MéTODO DE COMUNICAçãO PARA A MESMA". Em uma rede de comunicação móvel celular, registros móveis são mantidos em um primeiro banco de dados para indicar uma área de estação base quando uma estação móvel cruzar um limite entre áreas adjacentes de localização e entra naquela área de estação base. Um segundo banco de dados está associado com cada grupo de controle de áreas de estação base para manter registros móveis para indicar uma área de estação base quando a estação móvel sucessivamente cruzar um limite entre áreas adjacentes de estação base. Em resposta a um pedido de chamada, um dos registros móveis do primeiro banco de dados é acessado para identificar um grupo de controle de áreas de estação base e produzir um pedido de busca. Em resposta ao pedido de busca, um dos registros móveis do segundo banco de dados é acessado e um sinal de aviso é radiodifundido para pelo menos uma área de estação base indicada no registro móvel acessado para esperar por uma resposta da estação móvel. Se não houver resposta de retorno, o sinal de aviso é radiodifundido para as áreas remanescentes de estação do grupo de controle identificado.
