Abstract
método e aparelho de atualização de chave. um método de atualização de uma chave é fornecido pela presente invenção, onde quando um contador em uma camada de protocolo de convergência de dados em pacote pdcp de um suporte de rádio rb alcança um limite, um dispositivo móvel recebe uma mensagem de transferência de célula, restabelece as camadas pdcp e camadas de controle de link de rádio rlc para todos os rbs, mantém a informação de alinhamento de tempo de uplink, recurso de concessão de uplink para o canal compartilhado de uplink e recursos de canal de controle de uplink físico alocados de forma semiestática, e nivela um armazenador de uma camada de controle de acesso a meio mac; o dispositivo móvel obtém uma nova chave raiz, e obtém uma nova chave de criptografia e proteção de integridade de um plano de controle de recurso de rádio de acordo com a nova chave raiz; o dispositivo móvel transmite uma mensagem de transferência de célula completada pela nova chave de criptografia e proteção de integridade. dessa forma, um processo de acesso randômico iniciado pelo dispositivo móvel é evitado e o retardo de interrupção causado pelo acesso randômico iniciado pelo dispositivo móvel é, dessa forma, evitado. um dispositivo móvel e um nó de rede também são fornecidos pela presente invenção.
