Problems solved by technology

[0006] Because the Um interface of the GSM-R network is a wireless interface, it is easily affected by external interference, which will lead to an increase in the communication bit error rate and even communication failure. Therefore, it is found that the interference of the Um interface is to analyze the reasons for the high bit error rate and call drop of the Um interface. important means
In addition, when the BTS fails, or the vehicle-mounted MS fails, especially when there is a problem with the wireless signal of these devices, the data through other wired interfaces is often not enough to analyze the problem

Embodiment 1

[0038] Embodiment one, a kind of GSM-R network Um interface monitoring system, comprises:

[0039] One or more Um receivers are used to receive uplink and downlink wireless signals transmitted in each time slot of the Um interface in the GSM-R network, perform synchronization and demodulation, and extract bit information carried on the wireless signals;

[0040] The data processing center is used to convert and parse the bit information obtained by the Um receiver into layer 2 and layer 3 data and signaling according to the relevant 3GPP protocol; User classification, that is, to pick out the signaling belonging to the same user, so that user tracking can be realized.

[0041] The data storage server is used to save the signaling and data obtained by the data processing center.

[0042] In this embodiment, the unique subscriber identifier may be, but not limited to, an IMSI (International mobile subscriber identity, International Mobile Subscriber Identity).

[0043] Since i...

Abstract

The invention discloses a GSM-R network Um interface monitor system, comprising: one or a plurality of Um receivers for receiving uplink and downlink wireless signals transmitted by time slots in an Um interface of a GSM-R network, synchronizing and demodulating the signals and extracting bit information carried in the wireless signals; a data processing center for converting and analyzing the bit information obtained from the Um receivers as data and signaling, and classifying the signaling based on users in accordance with a user unique identifier carried in the signaling; and a data storage server for storing the signaling and the data which the data processing center obtains. The system can provide monitor data of the Um interface, supporting the optimization and operational maintenance for the GSM-R network.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a GSM-R network Um interface monitoring system. Background technique [0002] Railway locomotive integrated wireless communication equipment (hereinafter referred to as CIR) is used in the GSM-R system on the railway, installed on the train locomotive, and used by the driver. The equipment replaces the original wireless train dispatching communication system on the railway, and provides voice and data transmission channels between the locomotive and the ground. [0003] Train control on-board equipment OBU is a communication unit installed on trains in CTCS-3 train control system and ETCS-2 train control system. It uses the circuit data service of the GSM-R network as a transmission channel for train control commands. [0004] In order to ensure that on-board communication equipment such as CIR and OBU can stably provide GSM-R voice and circuit data transmission channels, it is necessary...
