Description

Technical Field

[0001] This invention relates to the field of low-altitude networking technology, specifically to a networking method, storage medium, device, and computer program product utilizing low-altitude flying intelligent agents. Background Technology

[0002] Low-altitude networking is a crucial component of the low-altitude economic development. It enables data transmission between satellites and low-altitude flying intelligent agents, which then transmit the data back to ground terminals in real time, thereby improving data transmission security and efficiency.

[0003] However, because low-altitude flying agents are in dynamic flight, they encounter various complex communication environments. For example, when a low-altitude flying agent moves from the coverage area of ​​one satellite to the coverage area of ​​another, or encounters signal interference or obstruction, the communication link may be affected, leading to a decrease in communication quality or even interruption. The interruption of the communication link will change the network topology 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 may mistakenly believe that the data packet is lost, thus performing message retransmission and congestion control, resulting in data congestion. Furthermore, during the transmission of data from the low-altitude flying agent to the ground terminal, the channel bandwidth capacity in the communication link is limited. When the amount of data transmitted by the low-altitude flying agent to the ground terminal exceeds the channel bandwidth capacity, congestion will occur. Especially in the case of high-speed data transmission, if the channel bandwidth is insufficient to support real-time data transmission, it will lead to data backlog and delay. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a networking method, storage medium, device, and computer program product utilizing low-altitude flying intelligent agents. By employing an inter-satellite handover strategy, it improves communication quality and avoids data transmission congestion between satellites and low-altitude flying intelligent agents. Simultaneously, it transmits data from low-altitude flying intelligent agents to ground terminals according to service data priority, thus avoiding channel congestion.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a networking method utilizing low-altitude flying intelligent agents, specifically including the following steps:

[0006] Step S1: Establish a communication link between the Qianfan satellite and the low-altitude flight agent based on the inter-satellite handover strategy, and transmit business data to the low-altitude flight agent through the established communication link;

[0007] Step S2: When the low-altitude flight intelligent agent forwards service data to the ground terminal, it determines the priority of the service data based on the historical service weight of the service data to be forwarded, and forwards the service data to the corresponding ground terminal in an orderly manner according to the priority of the service data.

[0008] Furthermore, the Qianfan satellite is composed of geostationary orbit (GEO) satellites, low Earth orbit (LEO) satellites, and very low Earth orbit (VLEO) satellites, forming inter-satellite links between GEO and GEO satellites, between LEO and LEO satellites, between VLEO and VLEO satellites, between GEO and LEO satellites, between LEO and VLEO satellites, and between GEO and VLEO satellites.

[0009] Further, step S1 includes the following sub-steps:

[0010] Step S1.1: Real-time acquisition of the position, channel capacity, and load status of each satellite in the Qianfan satellite system, as well as the position of the low-altitude flying intelligent agent;

[0011] Step S1.2: Determine the elevation angle evaluation index between the satellite and the low-altitude flying intelligent agent based on the position of each satellite and the position of the low-altitude flying intelligent agent, and determine the evaluation index of satellite channel capacity load balancing based on the channel capacity and load of the satellite.

[0012] Step S1.3: Weight the elevation angle evaluation index of the satellite and the low-altitude flight agent and the satellite channel capacity load balancing evaluation index to obtain the comprehensive evaluation score of the inter-satellite handover strategy. Establish a communication link between the satellite with the highest comprehensive evaluation score and the low-altitude flight agent, and transmit the service data to the low-altitude flight agent through the established communication link.

[0013] Furthermore, the process for determining the elevation angle evaluation index of 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 agent based on the position of each satellite and the position of the low-altitude flying agent:

[0015]

[0016] in, Indicates the current longitude of the satellite's orbit. θ represents the current longitude of the low-altitude flying agent, and θ represents the current latitude of the low-altitude flying agent;

[0017] ii. Set the elevation angle limit E between the satellite and the low-altitude flying intelligent agent. min The elevation angle evaluation index of each satellite relative to the low-altitude flying intelligent agent was calculated.

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

[0019] Furthermore, the calculation process for the comprehensive evaluation score of the inter-satellite handover strategy is as follows:

[0020] F = αF1 + βF2

[0021] Where F represents the comprehensive evaluation score of the inter-satellite handover strategy, F1 represents the elevation angle evaluation index of 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.

[0022] Furthermore, the present invention also provides a computer-readable storage medium storing a computer program, including: the computer program causing a computer to execute the computer program to implement the networking method using low-altitude flying intelligent agents when executed by a processor.

[0024] Furthermore, the present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the networking method utilizing low-altitude flying intelligent agents.

[0025] Compared with existing technologies, this invention has the following beneficial effects: The inter-satellite handover strategy in the networking method of low-altitude flying intelligent agents improves communication quality and avoids data transmission congestion between satellites and low-altitude flying intelligent agents by comprehensively considering the evaluation indicators of the elevation angle of satellites and low-altitude flying intelligent agents, as well as the evaluation indicators of satellite channel capacity load balancing. The elevation angle directly affects the signal transmission quality and communication stability; selecting satellites with larger elevation angles for communication can reduce the impact of signal attenuation and shielding effects. The channel capacity of a satellite determines the amount of communication it can handle simultaneously; prioritizing satellites with larger channel capacity and lighter current loads for communication can avoid excessive satellite load, improving the utilization and stability of the entire communication link and reducing data transmission congestion. Furthermore, transmitting data from low-altitude flying intelligent agents to ground terminals according to service data priority can further avoid channel congestion. This invention's networking method using low-altitude flying intelligent agents enables efficient low-altitude networking, improves data transmission quality and efficiency, and provides a reliable foundation for the development of the low-altitude economy.

[0027] Figure 2 This is a schematic diagram of the inter-satellite handover strategy in this invention. Detailed Implementation

[0028] The technical solution of the present invention will be further explained and described below with reference to the accompanying drawings.

[0029] like Figure 1 This is a flowchart of the networking method for low-altitude flying intelligent agents according to the present invention. The networking method specifically includes the following steps:

[0030] Step S1: Since the coverage of each satellite is limited, and the low-altitude flight agent may cross the coverage areas of different satellites during flight, in order to ensure that the low-altitude flight agent can continuously receive satellite signals during flight, this invention establishes a communication link between the Qianfan satellite and the low-altitude flight agent based on the inter-satellite handover strategy, and transmits business data to the low-altitude flight agent through the established communication link, thereby improving the continuity and stability of communication and avoiding the data transmission congestion problem between the satellite and the low-altitude flight agent.

[0031] In this invention, the Qianfan satellite consists of a geostationary orbit (GEO) satellite, a low Earth orbit (LEO) satellite, and a very low Earth orbit (VLEO) satellite, forming inter-satellite links between GEO and GEO satellites, between LEO and LEO satellites, between VLEO and VLEO satellites, between GEO and LEO satellites, between LEO and VLEO satellites, and between GEO and VLEO satellites. Because the Qianfan satellite is a low Earth orbit satellite, the communication latency of the inter-satellite links it forms is low.

[0032] Step S1 of the present invention is as follows Figure 2 As shown, it includes the following sub-steps:

[0033] Step S1.1: Real-time acquisition of the position, channel capacity, and load status of each satellite in the Qianfan satellite system, as well as the position of the low-altitude flying intelligent agent;

[0034] Step S1.2: Determine the elevation angle evaluation index between the satellite and the low-altitude flying agent based on the position of each satellite and the position of the low-altitude flying agent, and determine the satellite channel capacity load balancing evaluation index based on the satellite's channel capacity and load. The elevation angle directly affects the signal transmission quality and communication stability. Selecting satellites with larger elevation angles 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 simultaneously. Prioritizing satellites with larger channel capacity and lighter current load can avoid excessive satellite load, improve the utilization and stability of the entire communication link, and reduce data transmission congestion. Specifically, the process of determining the elevation angle evaluation index between the satellite and the low-altitude flying agent is as follows:

[0035] i. Determine the elevation angle E between the satellite and the low-altitude flying agent based on the position of each satellite and the position of the low-altitude flying agent:

[0036]

[0037] in, Indicates the current longitude of the satellite's orbit. θ represents the current longitude of the low-altitude flying agent, and θ represents the current latitude of the low-altitude flying agent;

[0038] i. Set the elevation angle limit E for satellites and low-altitude flying intelligent agents. min The elevation angle evaluation index of each satellite relative to the low-altitude flying intelligent agent was calculated.

[0039] The process for determining the evaluation metrics for satellite channel capacity load balancing is as follows: obtain the maximum channel capacity and current channel load of each satellite, and calculate the evaluation metrics for channel capacity load balancing for each satellite.

[0040] Step S1.3: Weight the elevation angle evaluation index of the satellite and the low-altitude flight agent and the satellite channel capacity load balancing evaluation index to obtain the comprehensive evaluation score of the inter-satellite handover strategy. The higher the comprehensive evaluation score, the greater the elevation angle between the satellite and the low-altitude flight agent and the greater the channel capacity. The better the communication quality of the satellite, the higher the comprehensive evaluation score. Establish a communication link between the satellite with the highest comprehensive evaluation score and the low-altitude flight agent, and transmit the service data to the low-altitude flight agent through the established communication link.

[0041] The calculation process for the comprehensive evaluation score of the inter-satellite handover strategy in this invention is as follows:

[0042] F = αF1 + βF2

[0043] Where F represents the comprehensive evaluation score of the inter-satellite handover strategy, F1 represents the elevation angle evaluation index of 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.

[0044] Step S2: When the low-altitude flight agent forwards service data to the ground terminal, it determines the priority of the service data based on the historical service weight of the service data to be forwarded, and forwards the service data to the corresponding ground terminal in an orderly manner according to the priority of the service data. This can further avoid channel congestion between the low-altitude flight agent and the ground terminal and ensure high-quality data transmission.
