Abstract

<B>TERMINAL MóVEL E ESTAçãO DE BASE EM UMA REDE DE SERVIçOS DE RáDIO EM PACOTE<D> é descrito um terminal móvel para comunicação com uma estação de base em uma rede de serviços de rádio em pacote. O terminal tem um processador para determinar um de diversos canais para comunicação entre o terminal móvel e a estação de base, codificar a fala de modo digital, para fornecer informações de fala, montar informações de fala em pacotes de fala e gerar solicitações de alocação de canal para um canal do qual enviar pacotes de fala. Um transmissor de rádio é fornecido para transmitir as solicitações e os pacotes para uma estação de base na rede. Um receptor de rádio recebe identidades de canais alocados pela estação de base nos quais o terminal móvel pode transmitir. O processador é responsivo a cada alocação de canal recebido para determinar que pacotes são enviados no canal alocado. No GPRS uma vez que um canal é liberado quando não há pacote para transmissão, níveis de tráfego mais elevados podem ser obtidos utilizando-se o mesmo número de canais de rádio.
