[0075] Embodiment 3:

[0076] The embodiment of the present invention provides a dynamically adaptive low-altitude flight communication network system, a routing module, including:

[0077] The first node location unit: determines whether there is any node in the optimal communication route of the low-altitude aircraft in the previous specified time period of the current specified time period that is consistent with the real-time position of the low-altitude aircraft; if so, determines that the node in the optimal communication route that is consistent with the real-time position of the low-altitude aircraft is the node at the first node position of the optimal path of the current specified time period; if not, determines that the node in the optimal communication route that is closest to the real-time position of the low-altitude aircraft is the node at the first node position of the optimal path of the current specified time period;

[0082] Actual communication routing unit: Determines the actual communication route of each low-altitude aircraft based on the optimal path, real-time status information, and real-time environmental information of each low-altitude aircraft.

[0083] In this embodiment, the optimal communication route node positions of the aircraft in the current specified time period and the previous specified time period are compared to determine whether the current real-time position of the aircraft is consistent with a node in the optimal communication route of the previous period. If they are consistent, the node is regarded as the first node of the optimal path of the current period; if they are inconsistent, the optimal communication route node of the previous period that is closest to the real-time position of the aircraft is selected as the first node of the optimal path, ensuring that the aircraft can start path selection based on its actual position.

[0084] In this embodiment, once the first node is determined, the next node of the first node is determined from the optimal communication route of the previous cycle and used as the second node of the optimal path of the current cycle. This step helps maintain the continuity and stability of the communication link by continuing along the historical optimal path.

[0085] In this embodiment, when the aircraft has approached the end point along the optimal communication route, the position of the last node in the optimal path is locked, and the next node thereafter is determined as the first node of the optimal communication route, which means that the communication path is cyclic.

[0086] In this embodiment, each aircraft determines the nodes at all node positions to generate the optimal path for each aircraft.

[0087] In this embodiment, for example: the optimal communication path of the i-th low-altitude aircraft is {node 1, node 2, node 3, ..., node iN1}, the node at the first node position of the optimal path of the i-th low-altitude aircraft is determined to be node 2 in the corresponding optimal communication route, then the node at the second node position of the optimal path of the i-th low-altitude aircraft is determined to be node 3 in the corresponding optimal communication route, after locking the position of node iN1 in the optimal communication route of the i-th low-altitude aircraft in the corresponding optimal path, node 1 in the optimal communication route of the i-th low-altitude aircraft is determined to be the node at the next node position of the node position of node iN1 in the corresponding optimal path, and the node optimal path determined based on all node positions of the i-th low-altitude aircraft is expressed as {node 2, node 3, ..., node iN1, node 1}

[0088] The beneficial effects of the above technical solution are as follows: based on real-time status information and real-time environmental information, the optimal path for each low-altitude aircraft is determined, and the actual communication route of each low-altitude aircraft is determined, which can improve the accuracy of low-altitude aircraft path selection, make the network system more flexible and intelligent in responding to environmental changes, enhance the sustainability of the path, and adapt to complex flight and communication environments.

[0095] Actual communication routing subunit: Determine the actual communication route of each low-altitude aircraft based on the adjusted paths corresponding to all node paths with available values ​​of 1 and all node paths with available values ​​of 0 in the optimal path of each low-altitude aircraft.

[0096] In this embodiment, when the available value of a node path is 0, the path is determined to be a failed path, and the system will look for an alternative adjustment path based on the current real-time status and environmental information to ensure that the aircraft communication is not interrupted.

[0097] In this embodiment, the actual communication route is determined based on the following path:

[0098] In this embodiment, all node paths with available values ​​of 1 are normal working paths; and the adjustment paths corresponding to the node paths with available values ​​of 0 are standby paths that replace the failed paths. Combining the above two types of paths, the actual communication route of each low-altitude aircraft is generated.

[0099] In this embodiment, the distance of the node path represents the physical straight-line distance between two communication nodes.

[0100] In this embodiment, the received power indicates the signal power at the receiving end on the communication link, reflecting the signal strength and transmission quality.

[0101] In this embodiment, the interference power indicates the power of other signal interferences that the communication link receives during signal transmission.

[0102] In this embodiment, the available value indicates a status flag of a node path. An available value of 1 indicates that the path is available, and an available value of 0 indicates that the path is invalid.

[0135] In this embodiment, the communication information overload area indicates an area where resource demand exceeds available communication resources, resulting in congestion.

[0136] In this embodiment, the communication information redundant area indicates an area where resource demand is far lower than resource supply, and resources are underutilized.

[0137] In this embodiment, the partitioned area with communication resource overload is divided into multiple partitioned sub-areas to disperse the load, and intelligent partitioning is performed according to the communication resource distribution characteristics (such as load density, node distribution, etc.). Each sub-area is allocated independent communication resources, and the partitioned area is given a first mark to facilitate identification during subsequent network structure optimization.

[0138] In this embodiment, the divided areas with redundant communication resources are merged with the adjacent areas with the smallest communication resources. The adjacent areas with the smallest resources are selected through resource evaluation to merge to form a new merged area. The merged area is given a second mark to facilitate network structure optimization and identification.
