Problems solved by technology

[0004] In the prior art, during HAPS cooperative coverage, the HAPS whose energy consumption is higher than the first threshold switches all terminal devices in the overlapping coverage area of ​​two HAPSs to the adjacent HAPS. This HAPS cooperative coverage method has low flexibility and does not It is beneficial for HAPS whose energy consumption is higher than the first threshold to flexibly reduce energy consumption

Abstract

The embodiments of the present invention provide a method, device and system for the cooperative coverage of high altitude platform stations. With the method, device and system adopted, the flexibility of the cooperative coverage of the HAPSs (high altitude platform stations) can be improved. The method includes the following step that: a first HAPS acquires first location information and second location information, wherein the first location information is used for indicating the location of at least one terminal device, and the second location information is used for indicating the locationof at least adjacent HAPS adjacent to the first HAPS; and the first HAPS determines at least one device to be switched from at least one terminal device according to the first location information and the second location information, and the first HAPS shrinks a coverage area according to the at least one device to be switched.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method, device and system for cooperative coverage of high-altitude platform stations. Background technique [0002] Stratospheric communication refers to communication using High Altitude Platform Stations (HAPS) located in the stratosphere as a base station. Among them, the HAPS can use aerial platforms such as balloons, airships and drones to provide network coverage to remote areas. The coverage area of ​​HAPS is much larger than that of traditional base stations, and because HAPS is much higher than the ground, its fading model is closer to the line-of-sight propagation model in an ideal environment, the channel fading per unit distance will be greatly reduced, and the propagation distance will be offset to a certain extent Signal loss caused by going too far. [0003] HAPS located in the stratosphere uses a combination of solar power and batt...
