Method of implementing calls in GSM-R

Abstract

The invention relates to a method for realize calling in the GSM-R, which comprises: setting the relationships between the train identification mark information, the station position information and the calling number of front and next stations; the mobile exchange center builds the information in the message to attain the calling train identification mark information and present train position according to received calling that said train calls nearby station; said mobile exchange center sets the calling number of called station according to the relationship, attained train identification mark information and train present position and sends calling. The invention can make the train call the front / next station of its present position via the fixed front / next station number at any position. The calling number of each station can be centralized maintained. The inventive method is simple which can improve the safety of train.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing calling in GSM-R. Background technique [0002] GSM-R (Integrated Railway Mobile Communication System) based on the GSM system includes three subsystems: BSS (Base Station Subsystem), NSS (Network Subsystem), and OSS (Operation Maintenance Subsystem). [0003] Cell location-based routing is one of the main features of GSM-R. Cell location-based routing means that the communication network determines the destination address routing based on the short number dialed by the mobile user and the cell location of the mobile user itself. figure 1 Shown: figure 1 In , the communication equipment of the same locomotive dials 1800 in the coverage area of ​​station A to connect to station A, and dials 1800 in the coverage area of ​​station B to connect to station B. [0004] In the actual operation of the railway, the locomotive often needs to call the ...

Problems solved by technology

[0006] In this method, since the terminal numbers of each station are scattered and stored in the locomotive communication equipment of each locomotive, when the terminal number of the station changes, when the station call number is increased or decreased, when the locomotive or the locomotive communication equipment adjusts the operating section, it must be updated The call number book stored in the relevant locomotive communication equipment is not conducive to the maintenance of call numbers at each station; moreover, due to GPS positioning, there are unsafe factors such as long time for establishing a link between the GPS ground device and the satellite, GPS satellite failure or unavailability, etc., so that the train's Normal operation is affected
