Problems solved by technology

[0005] However, the existing research work on handover in the GMS-R network has taken into account the particularity of the GSM-R network, such as the uniqueness of the running direction, the fixedness of the running track, the high speed of running, and the particularity of network coverage, etc. , the implementation is hard handover, that is, there is a problem of handover interruption
With the continuous improvement of the speed of high-speed railways, the requirements for the communication system are more stringent, and during the communication interruption time caused by the handover, the distance of the train r

Embodiment Construction

[0037] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0038]Such as figure 1 As shown, the dual-antenna handover system in the GSM-R network of the present invention consists of the first antenna 101 positioned at the head of the car, the tail antenna 102 positioned at the rear of the car and the controller 103 of the two antennas, wherein the first antenna 101 and the tail antenna The antennas 102 are respectively provided with different user identification codes for distinction, and the controller 103 is used to control the two antennas to receive signals, send signals and switch functions. Specifically, the controller 103 judges the location according to the received signal strength, and at different locations, the first and last antennas adopt different multiframe channel models t...

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-...
