Abstract

MÉTODO E APARELHO DE MANIPULAÇÃO DE TRANSFERÊNCIA. Modalidades deste pedido fornecem um método e aparelho de manipulação de transferência. O método inclui: receber, por uma primeira função de gerenciamento de acesso e mobilidade AMF, uma mensagem de solicitação de transferência enviada por um primeiro dispositivo de rede de acesso; armazenar, pela primeira AMF, um primeiro contexto de segurança de estrato de não acesso NAS ao determinar que derivação de chave precisa ser realizada, onde o primeiro contexto de segurança de NAS é um contexto de segurança de NAS gerado por meio de negociação entre a primeira AMF e o equipamento de usuário UE; e retomar, pela primeira AMF, o uso do primeiro contexto de segurança de NAS. Nas soluções técnicas fornecidas na presente invenção, quando uma transferência de dispositivo de rede de acesso falha, pode ser garantido que um contexto de segurança no equipamento de usuário é o mesmo que um contexto de segurança na primeira AMF, e ainda garantido que uma chave no equipamento de usuário é a mesma que uma chave na primeira AMF.
