Abstract

The embodiments of the invention disclose a data transmission method and related devices. The method may include the following steps that: a network device generates first downlink control signaling,wherein the first downlink control signaling carries a first quality of service (QoS) flow identifier and a reflected QoS identifier, wherein the reflected QoS identifier is used to indicate that theturning off of a terminal device or the enabling of a reflective QoS function; and the network device sends the first downlink control signaling to the terminal device by using a first data radio bearer (DRB). With the data transmission method and related devices provided by the embodiments of the present invention adopted, a current reflective QoS function can be effectively disabled when the terminal device does not receive a downlink data packet again.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission and related equipment. Background technique [0002] When the network is congested, all data streams may be discarded. In order to meet the user's requirements for different quality of service for different applications, the network needs to be able to allocate and schedule resources according to the user's requirements, and provide different data streams for different data streams. service quality. For example, priority is given to important data packets with strong real-time performance, and low processing priority is provided for ordinary data packets with low real-time performance, and they are even discarded when the network is congested. Quality of service (QoS) means that a network can use various basic technologies to provide better service capabilities for designated network communications. It is a security mechanism of the network and is used ...
