Abstract

MéTODO E SISTEMA PARA FORNECER ACESSO A UM CANAL PARA TRANSMISSõES DE VOZ Em um sistema TUMA que compreende uma pluralidade de unidades do assinante e uma pluralidade de rádios base, um método e um sistema para fornecer acesso a um canal para transmissões por voz, onde a primeira unidade do assinante determina se é provisionada para acesso "gentil" ao canal. Além disso, a primeira unidade do assinante é caracterizada por um primeiro código de cor e um primeiro ID de grupo de conversa. A primeira unidade do assinante também examina as transmissões de voz no canal de uma segunda unidade do assinante com um segundo código de cor e um segundo ID de grupo de conversa. Se o primeiro código de cor e o segundo código de cor combinarem e se o primeiro 21 de grupo de conversa e o segundo ID de grupo de conversa combinarem, então a primeira unidade do assinante pode acessar o canal para transmissões por voz, mesmo que o canal esteja sendo usado para transmissões por voz da segunda unidade do assinante.
