Railway marshalling stations and GSM-R network planning method

Abstract

The invention provides a global system for mobile communications for railway (GSM-R) network planning method for railway marshalling stations and radio-sharing sections, which comprises: setting railway lines and relative positions of base stations of marshalling stations, and determining the distance between the base stations; counting the inter-cell telephone traffic between cells along the railway lines and analyzing the needs for channels between the cells along the railway lines; analyzing the channel needs of a marshalling station service; calculating a set distance between base stations sharing the same adjacent channels and making a combined frequency plan for the railway lines and the marshalling stations; if the frequency resources allocated to the marshalling stations after the combined frequency plan is made cannot satisfy the needs of the service and the channel resource allocated to the cells on the lines are abundant, transmitting signals of the base stations of the railway lines to the marshalling station areas at a repeater radio frequency; and realizing regional subscription roaming restriction to perform the local roaming contracted restriction on users of different networks. The method provided by the invention can improve the frequency utilization rate of the railway marshalling stations and setting railway line radio-sharing sections.

Description

technical field [0001] The invention relates to a planning method of a wireless communication network, in particular to a method for planning a GSM-R network used in railway marshalling yards and merging areas. Background technique [0002] GSM-R (GSM for Railway) is an integrated digital mobile communication system for railways based on the public mobile communication technology of the wireless communication network, which develops together with the wireless communication network and can replace various existing railway communication and control systems with a single platform. At present, my country's GSM-R network coverage method adopts single-network interleaving redundant coverage, that is, the field strength of two adjacent base stations covers each other to the location of the adjacent base station, so as to improve the threshold level of communication switching. In case of failure, users in the base station can still access the network of adjacent base stations, so as ...

Problems solved by technology

When the existing railway marshalling yards and railway lines are paralleled, because the GSM-R system only has a 4MHz spectrum bandwidth, the joint frequency planning of the parallel railway marshalling yards and railway lines can be allocated to the parallel marshalling under the general network planning method The frequency resources of the station are very limited, and the frequency utilization rate is low. When the business volume of the railway marshalling station is large and the frequency demand is large, if sufficient frequency resources cannot be allocated, all the business needs of the marshalling station cannot be met. This situation limits my country's railway construction development
