Abstract

"MéTODO PARA PROTEGER TRáFEGO EM UMA REDE DE ACESSO DE RáDIO, ESTAçãO MóVEL PARA OPERAçãO EM UMA REDE DE ACESSO DE RáDIO, E, CONTROLADOR DE REDE DE RáDIO PARA UMA REDE DE ACESSO DE RáDIO". Um método para proteger tráfego em uma rede de acesso de rádio conectada a pelo menos duas redes de núcleo (CN). O método inclui manter um protocolo de autenticação específico de rede de núcleo e um processo de cifragem específico de portador de rádio, e gerar, para cada processo de cifragem, um parâmetro de contagem (C), incluindo um número de seq³ência cíclico (43) e um número de hiper-grupo (HFN), que é incrementado a cada vez que o número de seq³ência cìclico (43) completa um ciclo. Para cada rede de núcleo ou protocolo de autenticação, um primeiro portador de rádio de uma sessão é iniciado (5-8) com um HFN que excede o HFN mais alto usado durante a sessão prévia. Quando um portador de rádio novo é estabelecido, a estação-nióvel seleciona (5-10) o HFN mais alto usado durante a sessão para a rede de núcleo em questão, incrementa-o (5-12) e o usa para iniciar (5-14) o parâmetro de contagem para o portador de rádio novo. Ao término de uma sessão, a estação móvel armazena (5-16) pelo menos parte (41) do HFN mais alto usado durante a sessão.
