Abstract

as modalidades da descrição, no geral, referem-se à mudança da célula primária. um dispositivo de rede detecta se o contexto da camada 2 está sendo mantido e/ou uma ou mais células secundárias de serviço permanecem para uma mudança da célula primária para um dispositivo de terminal. então, o dispositivo de rede configura uma mensagem que indica a mudança da célula primária com base na detecção e transmite a mensagem para o dispositivo de terminal. o período de tempo de mudança da célula primária pode ser reduzido eficientemente e a transmissão de dados durante a mudança da célula primária pode ser otimizada.
