A haps communication channel allocation method, device and system

Abstract

The invention is suitable for the field of HAPS communication, and provides a method, device and system for distributing HAPS communication channels. The method comprises the following steps: in call admission or channel switch, respectively calculating the transmit-receive link distances between a calling party and high altitude platforms; detecting whether M high altitude platforms closest to the calling party meet the admission condition from small to large in sequence according to the transmit-receive link distances, if yes, terminating the detection, and if no, continuing detecting until the M high altitude platforms can be detected fully; and when the high altitude platforms meeting the admission condition are detected, accessing the calling party to the current high altitude platform, otherwise, blocking the calling party. The method, the device and the system monitor the transmit-receive link distances between the cell user and the high altitude platforms in a real-time manner to carry out dynamic wireless channel distribution, solves the problem that wireless resources cannot meet the user' requirement, which is caused by uneven load in the high altitude platform communication, and improves the overall performance of the system effectively.

Description

technical field [0001] The invention belongs to the field of high altitude platform stations (HAPS) communication, and in particular relates to a HAPS communication channel allocation method, device and system. Background technique [0002] The high-altitude platform communication network refers to a network composed of high-altitude platforms that are quasi-stationary and capable of loading payloads of a certain scale, with a height of about 20-100Km in near-earth space and permanent residence in space for 5-10 years. The high-altitude platform uses its good radio wave transmission characteristics to realize communication connections between ground users, between high-altitude platforms, or between high-altitude platforms and satellites. It has the advantages of flexible layout, wide application, low cost, safety and reliability, etc. extensive attention. [0003] Using multiple high-altitude platforms with the same bandwidth to serve a common area can greatly increase use...

Problems solved by technology

However, the existing channel allocation methods do not take into account the special structure of the high-altitude platform communication network, or cannot allocate channels fairly according to the type of business, or do not consider the service quality of each business when allocating channels
