Description

Technical Field

[0001] The present invention relates to the field of low-altitude networking technology, and in particular to a networking method, storage medium, device and computer program product utilizing a low-altitude flying intelligent body. Background Art

[0002] Low-altitude networking is an important part of the development of the low-altitude economy. It can use satellites to transmit data with low-altitude flying intelligent entities, and then use low-altitude flying intelligent entities to transmit the data back to ground terminals in real time, improving the security and efficiency of data transmission.

[0003] However, since the low-altitude flying intelligent body is in a dynamic flight process, it will encounter a variety of complex communication environments. For example, when the low-altitude flying intelligent body moves from the coverage area of ​​one satellite to the coverage area of ​​another satellite, or when encountering signal interference, occlusion, etc., the communication link may be affected, resulting in a decrease in communication quality or even interruption. The interruption of the communication link will change the topology of the network and trigger route reconstruction. If the route reconstruction time is much longer than the value of the retransmission timer set by the satellite, the satellite will mistakenly believe that the data packet is lost, and thus retransmit the message and perform congestion control, resulting in data congestion. In addition, since the channel bandwidth capacity in the communication link is limited during the process of low-altitude flying intelligent bodies transmitting data to ground terminals, congestion will occur when the amount of data transmitted by the low-altitude flying intelligent body to the ground terminal exceeds the bandwidth capacity of the channel. Especially in the case of high-speed data transmission, if the channel bandwidth is not enough to support real-time data transmission, it will cause data backlog and delay. Summary of the invention

[0004] In response to the problems existing in the prior art, the present invention provides a networking method, storage medium, device and computer program product utilizing low-altitude flying intelligent entities, which improve the communication quality through inter-satellite switching strategies and avoid data transmission congestion problems between satellites and low-altitude flying intelligent entities.

[0013] Furthermore, the process of determining the elevation angle evaluation index between the satellite and the low-altitude flying intelligent agent is as follows:

[0014] i. Determine the elevation angle E between the satellite and the low-altitude flying intelligent body according to the position of each satellite and the position of the low-altitude flying intelligent body:

[0017] ii. Set the elevation angle limit E between the satellite and the low-altitude flying agent min , calculate the elevation angle evaluation index between each satellite and the low-altitude flying agent

[0018] Furthermore, the process of determining the evaluation index of satellite channel capacity load balancing is as follows: obtaining the maximum channel capacity and current channel load of each satellite, and calculating the evaluation index of channel capacity load balancing of each satellite.

[0019] Furthermore, the calculation process of the comprehensive evaluation score of the inter-satellite switching strategy is:

Selecting a satellite with a larger elevation angle for communication can reduce the impact of signal attenuation and shielding effects; the satellite's channel capacity determines the amount of communication it can handle at the same time. Giving priority to satellites with larger channel capacity and lighter current load for communication can avoid the situation where the satellite is overloaded, improve the utilization and stability of the entire communication link, and reduce data transmission congestion.

[0040] Step S1.3, weight the elevation angle evaluation index of the satellite and the low-altitude flying intelligent body and the evaluation index of the satellite channel capacity load balancing to obtain a comprehensive evaluation score of the inter-satellite switching strategy. The higher the comprehensive evaluation score, the larger the elevation angle between the satellite and the low-altitude flying intelligent body, and the larger the channel capacity, and the better the communication quality of the satellite. A communication link is established between the satellite with the highest comprehensive evaluation score and the low-altitude flying intelligent body, and the business data is transmitted to the low-altitude flying intelligent body through the established communication link.

[0041] The calculation process of the comprehensive evaluation score of the inter-satellite switching strategy in the present invention is:

[0042] F=αF1+βF2

[0043] Among them, F represents the comprehensive evaluation score of the inter-satellite switching strategy, F1 represents the elevation angle evaluation index between the satellite and the low-altitude flying agent, α represents the weight of F1; F2 represents the evaluation index of satellite channel capacity load balancing, and β represents the weight of F2.
