Method, device and system for coordinated coverage of high-altitude platform stations

Abstract

Embodiments of the present invention provide a method, device and system for cooperative coverage of high-altitude platform stations, which can improve the flexibility of HAPS cooperative coverage of high-altitude platform stations. The method includes: the first HAPS acquires first location information and second location information, the first location information is used to indicate the location of at least one terminal device, and the second location information is used to indicate at least one terminal device adjacent to the first HAPS The position of an adjacent HAPS; the first HAPS determines at least one device to be switched from the at least one terminal device according to the first position information and the second position information, and the first HAPS narrows down the at least one device to be switched according to the at least one device to be switched coverage area.

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...

AI Technical Summary

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
