Abstract

TéCNICAS PARA ACESSAR UM SISTEMA DE COMUNICAçãO SEM FIO COM CAPACIDADE DE DESSINTONIZAçãO. Para acessar um primeiro sistema de comunicação, um terminal determina um tempo de transmissão para uma sonda de acesso, um tempo de resposta esperado a partir do sistema e um intervalo de tempo protegido com base no tempo de transmissão e/ou tempo de resposta esperado. O terminal determina um tempo inicial para enviar a sonda de acesso de tal forma que o intervalo de tempo protegido não se sobreponha a um intervalo de dessintonização no qual o terminal serve para monitorar outra freqUência/interface aérea. Tal tempo inicial pode ser ajustado inicialmente para o final de uma sonda de acesso anterior mais uma duração de aguardo pseudo-aleatória, podendo ser adiantado ou retardado no tempo, caso neâessário, por uma duração de tempo selecionada de tal forma que o intervalo de tempo protegido não se sobreponha ao intervalo de des sintonização.
