Abstract

resumo transmissão eficaz de recurso de rádio para comunicação de grupo sobre lte embms trata-se do fornecimento de um método para suportar comunicação de grupo através de mbms de lte. um ue primeiro estabelece uma portadora de serviço de pacote evoluído (eps) de difusão ponto a ponto em uma rede de lte para comunicação de grupo. o ue pertence a um grupo de comunicação que tem um id de grupo de comunicação. o ue recebe as informações de acesso a partir da rede para monitorar tráfego de multidifusão (dl) de transferência por enlace descendente da comunicação de grupo de dl com base em uma decisão de multidifusão. o ue está, então, pronto para monitorar uma portadora de serviço de multidifusão de difusão de multimídia (mbms) para receber o tráfego de multidifusão de dl. a portadora de mbms de multidifusão está associada a um identificador de grupo móvel temporário (tmgi), e em que o tmgi está associado ao id de grupo de comunicação. o ue desmultiplexa o tráfego de dl recebido a partir da portadora de mbms de multidifusão ou a partir da portadora de eps de difusão ponto a ponto em uma aplicação de comunicação de grupo única.
