Embodiment Construction

[0020] The dedicated air-to-air base station 10 will now be described first. The dedicated air-to-air base station 10 is realized by improving the existing mobile communication public base station, but it is quite different from the existing base station in the following aspects.

[0021] 1. Antenna radiation direction

[0022] The antenna of the present invention may adopt an existing base station antenna or a dedicated antenna.

[0023] In the base station in the existing public mobile communication network, in order to meet the normal communication needs of ground mobile users and effectively reduce the interference between users, the directional antenna angle is generally set to be inclined downward, and the general radiation direction of the omnidirectional antenna is also below the horizontal level, so that The antenna forms a downward beam to cover users in a sector area and reduce interference to adjacent sectors. In the present invention, however, the following impr...

Abstract

The invention relates to an aviation communication system and method, especially an aviation communication system and method for realizing ground-air and air-air communication based on public mobile communication network. Based on the existing national public mobile communication standard and criterion, it uses signalling channels, data service channels and voice service channels of wireless access networks of telecom operators (including GSM, GPRS, IS-95, CDMA2000, WCDMA, PHS, etc), establishes aircraft-oriented special air base station, special air repeater and partial existing public stations to cover air users in all air domain from horizon to top air, adopting mobile communication terminal meeting national and trade standard or custom terminal to realize ground-air and air-air communication. It can not only effectively solve ground-air and air-air communication in most areas in the land and the areas along the coast but also realize ground-air and air-air two-way data and voice communicating function at lower cost.

Description

technical field [0001] The present invention relates to an aeronautical communication system and method, in particular to an aeronautical communication system and method for realizing ground-air and air-air communication based on a public mobile communication network. Background technique [0002] During aviation flight, various information needs to be transmitted through the aviation communication system, such as for aircraft control, air traffic management, and information for aerial photography, measurement and control, and reconnaissance. [0003] At present, when conducting ground-to-air communication between the ground and various aircraft such as aircraft and air-to-air communication between aircraft, a traditional aviation communication method is to use specially developed dedicated communication equipment and dedicated frequency bands, and implement it according to a predetermined special communication protocol. The ground-to-air and air-to-air communications. For ...
