Abstract

"MéTODO E EQUIPAMENTO PARA EFETUAR REPASSE SUAVE EM UM SISTEMA DE COMUNICAçãO SEM FIO". São descritos um método e um equipamento para prover repasse suave em um sistema de comunicação móvel. Nos sistemas atuais, os membros de um Conjunto Ativo de estações base (4, 4A, 4B, 4C) são determinados comparando-se a energia medida do piloto com limites fixos. O valor de se prover um link de comunicação redundante para uma estação móvel (2) depende principalmente da energia de outros sinais sendo providos para a estação móvel (2). Na presente invenção, a força de sinal de cada sinal transmitido por outras estações base (4, 4A, 4B, 4C) em comunicação com uma estação móvel (2) é considerada quando se determina a adição ou não de uma estação base ao conjunto de estações base (4, 4A, 4B, 4C) em comunicação com a estação remota. Uma estação base é adicionada somente se o sinal recebido a partir de tal estação base proporciona valor adicionado suficiente para justificar o impacto sobre a capacidade do sistema.
