Abstract
Patente de Invenção: MéTODO E EQUIPAMENTO PARA REPASSE DURO EM UM SISTEMA CDMA. Em uma rede de comunicações, um usuário da rede se comunica por meio de uma unidade remota (30) com outro usuário através de pelo menos uma estação base (100). A rede de comunicações inclui um primeiro centro de comutação móvel (MSC-I) que controla as comunicações através de um primeiro conjunto de estações base incluindo uma primeira estação base (100). A unidade remota (30) armazena uma listagem de estações base ativas que possui uma entrada correspondente a cada estação base com a qual a comunicação ativa está estabelecida. A primeira estação base (100) possui uma entrada na listagem de estações base ativas. A primeira estação base (100) mede um retardo de ida e volta de um sinal de comunicação ativa entre a primeira estação base (100) e a unidade remota (30). Um repasse do sinal de comunicação ativa é iniciado se o retardo de ida e volta da comunicação ativa superar um limite se a primeira estação base (100) for designada como uma estação base referência. Alternativamente, a unidade remota (30) também armazena uma listagem de estações base canditadas, compreendendo uma entrada correspondente a cada estação base através da qual a comunicação ativa possa ser possível mas que não está estabelecida. Um repasse do sinal de comunicação ativa é iniciado se a listagem de estações base compreende uma entrada correspondente a um sinal piloto inicializador.
