Abstract
To keep up with the rapid development of railway and meet the high demand for communication business in China, Global System for Mobile Communications-Railway (GSM-R) based on General Packet Radio Service (GPRS) ahead of Europe has been developed. However, the current data communication mode of GPRS using TCP/IP has some disadvantages, such as poor mobility, lack of security etc. For this reason, there are some problems for GSM-R, like handover, which makes communication service quality undesirable. Named Data Networking focuses on named data, adopts data-facing communication mode, and does not care where the contents are stored but the contents themselves. It can effectively solve the problems caused by TCP/IP. In this paper, a new high-speed railway communication system with Named Data Networking (NDN) named NDN-GSM-R is proposed. Two simulations, called transmission interference time and end-to-end transmission delay of NDN-GSM-R, have been conducted. The simulation results show that NDN-GSM-R has better performance in high-speed mobile communication environment and can make up the insufficiency of the current GSM-R based on TCP/IP framework.
Highlights
Global System for Mobile Communications-Railway (GSM-R) [1] is the digital mobile communication system specially designed for railway communication
With the rapid growth of train speed, the packet data communication mode based on TCP/IP makes the GSM-R unable to deal with communication handover and other problems
Since Named Data Networking (NDN)-GSM-R is based on the original framework of GSM-R, NDN communication mode replaces the packet data communication mode based on TCP/IP
Summary
Global System for Mobile Communications-Railway (GSM-R) [1] is the digital mobile communication system specially designed for railway communication. A new high-speed railway communication system with NDN named NDN-GSM-R is proposed, and the simulations on the transmission interference time of NDN-GSM-R as well as the end-to-end transmission delay [8] have been conducted. The simulation results show that NDN-GSM-R has better performance in high-speed mobile communication environment and can make up the insufficiency of the current GSM-R based on TCP/IP framework.
