A method for data collection of gsm-r network interface

Abstract

The invention discloses and provides a data collection method for a GSM-R (Global System for Mobile for Railways) network interface. The data collection method includes that a signal connector is connected to an analog signal of the GSM-R network interface; a physical layer decoder converts the analog signal into a digital signal and processes the digital signal to obtain a data frame; a central processing unit sends a first decoding signal to a data link layer decoder; the data link layer decoder decodes the data frame according to the first decoding signal to obtain signaling data in the data frame; the central processing unit sends a second decoding signal to the data link layer decoder according to the signaling data; and the data link layer decoder decodes the data frame according to the second decoding signal to obtain valid data in the data frame and feed back to the central processing unit. The data collection method for the GSM-R network interface has the advantage of achieving collection of multiple data on various network interfaces in a GSM-R network.

Description

technical field [0001] The invention relates to the technical field of mobile communication networks, in particular to a GSM-R network interface data collection method. Background technique [0002] GSM-R (GSM for Railways) system is a comprehensive dedicated digital mobile communication system specially designed for railway communication. Based on the GSM (Global System of Mobile Communication, Global System for Mobile Communication) Phase2+ standard protocol, GSM-R has added functions such as location-based addressing and function addressing, and is suitable for railway communication, especially railway special dispatching communication. . [0003] At present, my country's GSM-R digital mobile communication system is mainly composed of seven subsystems: network switching subsystem, base station subsystem, operation and maintenance subsystem, general packet radio service subsystem, intelligent network subsystem, fixed access switching subsystem and terminal subsystem.

Problems solved by technology

[0010] Although the reference data types and the amount of data information are increased when using this system, there are still many defects, which are mainly reflected in: on the one hand, the data association is incomplete, and the current system fails to collect voice call data

On the other hand, the accuracy of data collection varies, and it is easy to make mistakes in association

The current system uses three different data acquisition devices to collect data from the three interfaces. Once the time accuracy of each device is different, it is easy to cause data association errors.
