Abstract

Embodiments of the present invention provide an information transmission method, network-side equipment, and a terminal. The method includes: generating a downlink control packet, the downlink control packet carrying a QoS flow identifier and a reflection identifier, and the Qos flow identifier is obtained from an application The QoS flow identifier added when the downlink data packet of the layer is mapped to a Qos flow, and the reflection identifier indicates whether to use the data wireless bearer used for sending the downlink data packet when the terminal receives the downlink data packet and feeds back the uplink data packet The DRBs with the same DRB perform the identification of the uplink data packet feedback; and send the downlink control packet to the terminal. The scheme of the invention reduces the overhead of the packet header when the Qos flow is mapped to the DRB, and improves the reliability of information transmission.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an information transmission method, network side equipment and terminal. Background technique [0002] The current LTE system adopts an end-to-end QoS management mechanism and differentiated services to meet the QoS requirements of different services. QoS is completed in the form of multiple layers, and the QoS management of the entire LTE network is achieved through figure 1 to achieve. E-RAB (evolved Radio Access Bearer, evolved radio access bearer) and Radio bearer (radio bearer) are the smallest units for QoS management on the EPS side and the RAN (radio access layer) side, respectively. EPS (Evolved Packet System) is a complete evolved packet system, which is composed of wireless network (LTE), core network (EPC) and user terminal (UE). [0003] Such as figure 2 As shown, in 5G, the downlink data packet (IP flow) first maps the downlink data packet fro...
