Abstract

"MéTODO E INDICADOR DE QUALIDADE DE SERVIçO DE DIFUSãO SEM FIO". A invenção descreve um método para estimar a qualidade de serviço de difusão sem fio em um canal de difusão incluindo as etapas de: receber (310) uma mensagem de parâmetro de serviço com um identificador de serviço associada a um canal de difusão, que determina (320) um limite indicador de qualidade da mensagem de parâmetro de serviço, que mede (340) um indicador de qualidade para formar um indicador de qualidade calculado (350), comparar (360, 370) o indicador de qualidade calculado ao limite indicador de qualidade. O limite indicador de qualidade pode ser embutido na mensagem de parâmetro de serviço ou obtido indiretamente como através de uma tabela que mapeia um identificador do serviço para um indicador de qualidade. Vários indicadores de qualidade estão disponíveis, incluindo várias proporções sinal-ruído (por exemplo, E~ b~/N~ t~) e proporção sinal piloto-ruído (C/I~ PICH~).
