Embodiment Construction

[0090] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Such as figure 1 Shown: method of the present invention comprises the following steps:

[0091] Step 1, ATG dedicated frequency analysis: conduct frequency resource analysis to determine whether ATG is likely to obtain dedicated frequencies; when ATG has the opportunity to obtain dedicated frequencies, even if the bandwidth is small, partial frequency reuse can be performed based on dedicated frequencies to reduce frequency reuse The difficulty of using; when the ATG network does not have a dedicated frequency band, it is necessary to adopt all the same frequency schemes, that is, the uplink of ATG multiplexes the uplink frequency of the ground network, and the downlink of ATG multiplexes the downlink frequency of the ground network. This symmetrical way ATG multiplexes the ground The frequency of the network is introduced into the ATG and the terrestri...

Abstract

The invention discloses an ATG networking solution based on space-ground co-frequency, which solves the bottleneck of ATG network development by introducing special products and solutions and adoptingoperator frequency to perform space-ground co-frequency, solves the problem of frequency resources of air-ground communication (ATG), and removes obstacles of ATG deployment. Through the antenna co-frequency scheme of the invention, the problem of obtaining frequency resources in ATG network deployment can be solved, the use efficiency of operator frequency resources is improved, the operation ishelped in efficiency and income improvement, and the operation is improved. The method has a wide development prospect in the aspects of value-added services, advertisements and digital and intelligent services of big data.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a solution for deploying an air-to-ground communication network (ATG) based on multiplexing the frequency of a ground mobile communication network, so as to realize Internet access in passenger cabins of civil aviation aircraft. Background technique [0002] At present, with the rapid development of mobile communication technology, mobile broadband services have also penetrated into people's lives. At present, high-speed Internet access for users has not yet been realized on civil aviation airliners, which is the last desert of mobile broadband services. The performance and cost of airborne satellite solutions are unsatisfactory. At present, the ground-air communication system (ATG) is the best solution to this problem. The ATG system is to cover the sky by deploying a wireless base station network on land, and install a receiving terminal (CPE) on the ...
