Abstract

MÉTODO DE HANDOVER, EQUIPAMENTO DE USUÁRIO E DISPOSITIVO DO LADO DA REDE. A presente invenção refere-se a um método de handover, a um Equipamento do Usuário, UE, (11) , e a um dispositivo do lado da rede (12 , 13), que podem encurtar um atraso de handover de um plano de controle e um atraso de interrupção de dados do plano do usuário. Um método de handover inclui: obter (21), por meio de um UE, um Avanço de Tempo, TA, de uma célula alvo antes de um handover, e obter (22) um grant de Enlace ascendente, UL Grant, emitido pela célula alvo com o TA em um recurso que é correspodente ao UL Grant. Um outro método de handover inclui: emitir (91), por meio de uma célula alvo, um TA da célula alvo para um UE através de uma célula fonte antes de um handover; e emitir (92) um UL Grant da célula alvo para o UE; e então receber (93) uma mensagem de Handover Completo que é emitida pelo UE com o TA em um recurso que é correspondente ao UL Grant.
