Abstract

Patente de Invenção: "PROTOCOLO DE CONTROLE DE ACESSO AOS MEIOS FISICOS COM PRIORIDADE E INTERVALOS LIVRES DE DISPUTA". Um esquema de disputa de acesso tendo ambos prioridades de múltiplos níveis e um indicador de acesso livre de disputa 130 para uso por uma estação 12 em uma rede de estações 10. Uma estação 12 tendo um quadro a transmitir determina a partir de um indicador de controle de disputa detectada 130 se é permitido disputar o acesso para um meio físico de transmissão 14 durante um período de disputa 290. A estação 12 determina se o indicador de controle de disputa 130 indica um acesso livre de disputa e, se o indicador de controle de disputa 130 indica um acesso livre de disputa, a estação 12 determina se um nível de prioridade de acesso ao canal associado com o quadro a ser transmitido é superior ao nível de prioridade de acesso ao canal 144 associado com um último quadro transmitido. Se afirmativo, a estação 12 detecta se qualquer estação na rede de estações 10 planeja disputar o acesso para o meio físico 14 em um nível de prioridade de acesso ao canal que é superior ao nível de prioridade de acesso de canal associado com o quadro a ser transmitido. Se afirmativo, a estação 12 sub-mete-se à disputa pelo acesso.
