Abstract

The present invention provides a data transmission method, network side equipment and communication system, wherein the method includes: determining multiple service data flows mapped to the same RB, and according to multiple QoS parameters corresponding to the multiple service data flows The transmission parameters and QoS configuration parameters of the RB are determined, so that multiple service data streams transmitted in the RB can reach the transmission target at the same time. The data transmission method, network side equipment, and communication system of the present invention can effectively solve the problem that QoS flows cannot meet service quality requirements caused by asynchronous arrival of different QoS flows, and significantly improve service guarantee capabilities and user experience.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, network side equipment and a communication system. Background technique [0002] In the 5G (fifth generation mobile communication technology) communication system, the concept of QoS (Quality of Service) flow is introduced. Each QoS flow represents a data flow, and has a QoS profile (configuration file) to indicate the transmission characteristics that need to be satisfied, including rate, delay, etc. After receiving a QoS flow, the user or network will map it to RB (Radio Bearer, resource block), such as figure 1 shown. New AS layer (SDAP, Service Data [0003] Adaptation Protocol, Service Data Adaptation Protocol) is responsible for the mapping process and adds header packets during processing, such as figure 2 shown. [0004] At present, in the 5G communication system, different QoS flows may be mapped to the same RB, and RB is t...
