AI Technical Summary

Technical Problem

Currently, 5G networks used for wireless communication in train control modules in railway environments suffer from high packet loss rates and excessive data latency. In particular, reliability and latency issues caused by handover and radio link failures affect the safety of train control.

Method used

By employing multipath transmission technology and lockout technology, multiple communication paths are established between multiple wireless transceivers through wireless communication equipment on the vehicle, and data replication packets are sent on each path. At the same time, channel selection during handover is restricted to reduce unnecessary handover and radio link failures.

Benefits of technology

It reduced packet loss rate, enhanced communication reliability, increased system throughput, reduced the number of data retransmissions, and ensured the stability and low latency of train control communication.

Abstract

According to an aspect of the present disclosure, the present disclosure relates to a wireless communication device on a vehicle. The wireless communication device includes, but is not limited to, a first wireless transceiver configured to transmit and receive data on a first communication path, a second wireless transceiver configured to transmit and receive data on a second communication path, and a processor electrically connected to the first wireless transceiver and the second wireless transceiver, and the processor is configured to at least establish a plurality of communication paths as a default communication mode, transmit, by the first wireless transceiver, a first data packet to a network located outside the vehicle on the first communication path as the default communication mode, and transmit, by the second wireless transceiver, a first duplicate data packet of the first data packet to the network on the second communication path as the default communication mode.
