Problems solved by technology

[0005] However, in some scenarios in practical applications, it is not only necessary to broadcast V2X messages in a large area, but also requires low transmission delay, and the forwarding process through V2X AS will cause excessive delay, which is difficult to meet user needs

Abstract

The invention provides a communication method and a related device, and the method comprises the steps that a user plane function UPF receives to-be-broadcasted user plane data from a first terminal,and transmits the to-be-broadcasted user plane data to a second terminal through a dedicated transmission channel. The dedicated transmission channel is a data transmission channel dedicated to downlink transmission of to-be-broadcasted user plane data from the UPF to the second terminal, and the user plane data downlink transmitted from the dedicated transmission channel to the second terminal isdesignated to be further broadcasted through the second terminal (such as broadcast through a PC5 interface), so that relatively low V2X communication time delay can be realized; user experience is enhanced.

Description

technical field [0001] The present application relates to the communication field, in particular to a communication method and device. Background technique [0002] As the automotive industry grows, so does vehicle technology. Vehicle to Everything (V2X) is the development trend and key technology of intelligent transportation in the future. As an extension of the Internet of Things, the Internet of Vehicles refers to the provision of vehicle information through terminals or sensors mounted on vehicles, vehicle terminals and electronic tags. Realize the communication between vehicle and infrastructure (Vehicle to Infrastructure, V2I), vehicle and vehicle (Vehicle to Vehicle, V2V), vehicle and mobile equipment (Vehicle to Nomadic devices, V2N) (collectively referred to as V2X communication), and use information technology to process data Extraction, sharing, etc. are effectively used to achieve effective management and control of vehicles and provide comprehensive services. ...
