Embodiment Construction

[0046]A low-altitude balloon-loaded relay emergency wireless data communication architecture, including a low-altitude wireless relay platform, a base station, and a mobile terminal. The low-altitude relay platform is carried by a balloon on a car, and consists of a spectrum sensing module, a communication module, a spectrum and a channel Management, communication gateway management module and GPS or Beidou positioning module. The low-altitude relay platform communicates with the external network through the backhaul link. The MT is distributed in the base station, and the mobile terminal is located on the car with the gateway function and the receiving node of the backhaul link. , able to communicate with the Internet backbone network; establish mutual communication links between multiple relay platforms.

[0047] The relay has a multi-radio interface, and each interface supports up to 4 frequency bands, and the terrestrial LTE terminal equipment and the base station support u...

Abstract

The invention provides a relay emergency wireless data communication frame. A relay net is formed by a single low-altitude relay platform; the relay platform is hung below a balloon tied on a rope fixed on a trolley; and an application scene is a land cellular network with one part of damaged base stations and fewer base stations (reserved base stations) which can realize physical connection. A low-altitude relay physical layer can utilize a cognitive radio technology to detect signal frequency spectrums of the reserved base stations so as to carry out radio resource management of emergency data communication; the relay platform can realize following functions: 1) connection close to line-of-sight propagation is provided for a land user; 2) the position of the relay platform is adjusted to guarantee that links among the relay platform and a plurality of land base stations have better channel quality; 3) a certain cognitive radio function is realized; 4) communication with an external network is realized by a gateway which is used as the reserved base station.

Description

technical field [0001] The invention relates to the field of wireless emergency communication, in particular to a low-altitude relay emergency wireless data communication method. Background technique [0002] The existing terrestrial cellular communication system is prone to be paralyzed after a large-scale geological disaster, and then the communication service function will be lost. At present, the relay emergency communication researched at home and abroad includes low-altitude relay platform and high-altitude relay platform. The low-altitude relay platform is relatively flexible, and the overhead and delay are smaller than the high-altitude platform, but the disadvantage is that the coverage is small, and it is easily affected by low air flow disturbance; the high-altitude relay platform has a large coverage, and the delay and overhead are smaller than satellite communications. Obviously larger than the low-altitude relay platform, the economic cost is usually relativel...
