Abstract

são descritos métodos, sistemas e dispositivos para comunicação sem fio. um equipamento do usuário (ue) pode estabelecer uma sessão de conectividade da rede de pacote de dados (pdn) para uma pdn usando uma tecnologia de acesso de rádio (rat) celular e migrar a sessão de conectividade pdn a partir de um nó de acesso (an) de origem para um an de destino. a migração pode iniciar quando é tomada a decisão de realizar um handover (transferência entre células). o an de destino pode receber um endereço de rede e informações sobre um primeiro link de rádio de dados estabelecido entre o ue e o an de origem. o an de destino pode estabelecer um segundo link de rádio de dados com o ue com base, pelo menos em parte, na primeira informação de link de rádio de dados, e pode transmitir, à pdn, uma atualização de caminho incluindo o endereço de rede e um caminho atualizado por meio do an de destino. em alguns casos, o an de destino pode encaminhar pacotes entre o ue e a pdn por meio do segundo link de rádio de dados.
