Abstract

The invention provides a method for setting the LTE network in a high-speed rail environment. The LTE network comprises N base stations and antennae, wherein N is larger than 1, the base stations are distributed on the two sides of a railway in a stagger and zigzag mode, the incidence angle theta of each base station is not smaller than 10 degrees, the vertical distance D between each base station and the edge of the railway meets the inequation that S / 2*tan theta<D<S / 2, S represents station spacing, and theta is the minimum incidence angle. By the adoption of the method, through targeted network plan of the high-speed rail scene, the high-quality LTE network can be provided for an operator, adverse effects caused by various factors during high-speed running of a train are reduced, signal quality is guaranteed, and user experience is improved.

Description

technical field

[0001] The invention relates to the communication field, in particular to a setting method of an LTE network in a high-speed rail environment. Background technique

[0002] The national high-speed railway planning and construction plan is that by 2020, express passenger transport channels will be established between provincial capitals and large and medium-sized cities, including "four vertical and four horizontal" railway express passenger transport channels and three intercity express passenger transport systems. It is estimated that by 2020, the mileage of China's high-speed railways with a speed of 200 kilometers per hour and above will exceed 18,000 kilometers, accounting for more than half of the total mileage of high-speed railways in the world.

[0003] High-speed high-speed rail covers a long mileage. Passengers who take high-speed high-speed rail have a lot of leisure time and have great demands on the network, including not only voice requirements,...

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] In this embodiment, an LTE network setting solution suitable for high-speed rail scenarios is proposed, which mainly includes the following aspects: base station location selection, coverage mode, equipment type selection, networking mode, and tunnel solution. The details will be described in detail below in conjunction with the accompanying drawings.

[0027] (1) Base station site selection

[0028] As the incident angle decreases, the penetration loss of the train car increases. When the incident angle θ is within 10 degrees, the magnitude of the train penetration loss is significantly a...
