Data transmission method, terminal device and network device

Abstract

The present application provides a data transmission method, a terminal device and a network device. The method includes: the terminal device acquires first configuration information, and the first configuration information includes at least a first bearer identifier and a path corresponding to the first bearer identifier Configuration information, the path configuration information corresponding to the first bearer identifier includes at least one of a direct link transmission path and a network device transfer transmission path; the terminal device obtains the first service data and the second service data corresponding to the first service data A bearer identifier; the terminal device selects a transmission path for the first service data according to the first bearer identifier, the second bearer identifier, and the path configuration information; the terminal device transmits the first service data on the transmission path. The method, terminal device and network device provided in this application can be applied to communication systems, for example, V2X, LTE‑V, V2V, Internet of Vehicles, MTC, IoT, LTE‑M, M2M, or Internet of Things, etc.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a data transmission method, a terminal device and a network device. Background technique [0002] With the continuous development of society, the popularity of cars is getting higher and higher. While driving travel brings convenience to people's travel, it also brings a certain negative impact on human society. The rapid increase in the number of vehicles has caused urban traffic congestion, A series of problems such as frequent traffic accidents and poor environmental quality. Therefore, in terms of personal safety, traffic efficiency, environmental protection, and economic effects, a complete intelligent transportation system (Intelligent Transportation System, ITS) is needed. [0003] Currently, vehicles can communicate through vehicle to vehicle (Vehicle to Vehicle, V2V), vehicle to roadside infrastructure (Vehicle to Infrastructure, V2I), vehicle to pedestrian ...

AI Technical Summary

Problems solved by technology

[0005] In the current technology, the path selection is decided by the application layer, and the working mechanism of the direct connection communication and the transfer transmission path of the network equipment is different, which leads to the inevitable introduction of potential risks when the mobile terminal performs path reselection or handover during the communication process. Large delay and service interruption
