5G networking system and method in high-speed rail scene

Abstract

The invention relates to a 5G networking system and networking method in a high-speed rail scene, and belongs to the field of communication, and the method comprises the steps: configuring IP addresses of a 5G small station and a unified management platform; starting the client and the first gateway, and establishing a special VPN tunnel between the 5G communication gateway and the unified management platform; completing the registration of the 5G small station through the special VPN tunnel; and transmitting data of the 5G small stations and the 5G users through the special VPN tunnel. In the embodiment of the invention, the train passes through the core networks of all provinces along the line in the running process, related configuration does not need to be carried out for legitimate network access of the 5G small station, and the operation and maintenance cost and the modification work are not increased. In the moving process of the train, the 5G users in the train are always registered to the unified management platform, and the service continuity is good. 5G small station configuration in the vehicle is simplified, and meanwhile, the deployment distance between macro stations along the line can be increased, so that the cost is reduced.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to a 5G networking system and method in a high-speed rail scenario. Background technique [0002] The 5G network still lacks comprehensive coverage support for the operation ecology of high-speed railways. The 5G network coverage solution needs to focus on site planning and layout, system switching overlapping area design, and frequency deviation correction to achieve better network performance. [0003] Such as figure 1 As shown, according to the traditional coverage method, the high-speed rail line coverage site is recommended to be arranged in a "zigzag" shape to maximize the coverage of the seats on both sides of the train, especially when the trains meet, to ensure in-car communication Best quality. [0004] The existing high-speed rail network scheme has the following problems: [0005] 1. It is unavoidable to avoid car body wear and tear, and the penetration loss ...

AI Technical Summary

Problems solved by technology

[0005]1. Unavoidable car body wear and tear, large penetration loss

Since the mainstream 3.5GHz frequency band of 5G is higher than that of 4G, high-speed rail coverage in the 5G era is more difficult, resulting in poor user experience

[0006]2. High cost, which will be 3-4 times of 4G network construction cost
