Abstract

The invention discloses a double-antenna handover system in the GSM-R (global system for mobile communication for railway) network and a method thereof. The double-antenna handover system comprises a head antenna provided with user identification codes, a tail antenna provided with user identification codes and a controller used for controlling received signals and transmitted signals of the head antenna and the tail antenna and handover of functions. By channel adjusting and coordinate of the head antenna and the tail antenna, seamless handover in the GSM-R network is realized, communication quality in the high-speed environment is greatly improved, and for a single-antenna handover process, time for transmitting measuring reports is shortened, and transmission efficiency is high.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a dual-antenna handover system and method in a GSM-R network. Background technique

[0002] Because high-speed railways are related to people's lives and property safety, with the rapid development of high-speed railways and the popularization and application of high-speed railway mobile communication systems, research on the safety of high-speed railway systems is a key topic in the field of high-speed railway research. As the wireless communication system GSM-R in the entire high-speed railway information system, due to the uncertainty of its wireless transmission, the security performance of the GSM-R system has aroused the interest of many researchers.

[0003] Handover in the GSM-R system refers to the process of transferring from a current call or data transmission channel to a new channel. In a high-speed railway system, handover is a key technology in GSM-...
