Abstract

Provided in an embodiment of the present invention are a service transmission method, network device and terminal, the method comprising: receiving data corresponding to a quality of service (QoS) flow of at least one broadcast / multicast service based on a packet data convergence protocol (PDCP) entity configured for the broadcast / multicast service; and transmitting data corresponding to at least one QoS flow to a plurality of target terminals through a multicast channel corresponding to the PDCP entity, and / or transmitting data corresponding to at least one QoS flow to a target terminal through a unicast channel corresponding to the PDCP. According to the scheme of the invention, the unicast link can be quickly and effectively utilized for retransmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a service transmission method, a network device and a terminal. Background technique [0002] In the Long Term Evolution (LTE) system, the Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) is used to transmit the Multimedia Broadcast Multicast Service (MBMS) service. The MBMS service is a For point-to-multipoint services, such as mobile TV, etc., MBSFN service transmission requires evolved NodeBs (evolved NodeBs, eNBs) of multiple cells in a certain MBSFN area (MBSFNArea) to transmit the same data at the same time. In this way, user equipment (User Equipment, UE) not only does not suffer from inter-cell interference when neighboring cells transmit data, but also benefits from the superposition of signals from multiple cells. UE receives and combines signals from multiple eNBs, which can improve signal-to-noise. It effectively improves ...
