Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground mobile communication system and satellite mobile communication system operate as separate independent networks, then each system can maintain its own operational simplicity and system stability, but resource utilization efficiency deteriorates and system integration capability is limited
Solution Approach 1:
The patent merges ground mobile communication system and satellite mobile communication system into a unified heterogeneous three-dimensional network. The network control unit coordinates both systems to share radio access resources, enabling seamless integration while maintaining operational stability through unified resource management and coordinated control mechanisms.
Solution Approach 2:
The network control unit is designed with universal functionality to manage both ground and satellite communication systems. It implements unified radio access technology that can operate across different network types, enabling a single control entity to handle diverse communication scenarios and resource allocation strategies.
2Area of stationary object
If terminal switches between ground and satellite communication modes, then communication coverage is maintained, but communication continuity deteriorates and switching overhead increases
Solution Approach 1:
The patent implements carrier aggregation technology that enables the terminal to simultaneously utilize both ground and satellite communication channels. This eliminates mode switching by maintaining continuous communication through multiple active links, ensuring seamless service delivery without interruption or overhead.
Solution Approach 2:
The network control unit dynamically allocates and aggregates carrier resources from both ground and satellite systems based on real-time channel conditions and service requirements. This dynamic resource orchestration allows flexible adaptation to changing environments while maintaining continuous communication without switching delays.
3Device complexity
If separate independent systems are used for ground and satellite communication, then system complexity is reduced and ease of operation is improved, but resource optimization capability deteriorates and waste increases
Solution Approach 1:
The network control unit serves as an intermediary that coordinates resource allocation between ground and satellite systems. It implements unified radio access technology and carrier aggregation management, optimizing resource utilization across the heterogeneous network while maintaining operational simplicity through centralized control and automated decision-making algorithms.

AI summary
A control method and a control device in a heterogeneous three-dimensional hierarchical network, and a communication system are provided. The control method includes: obtaining a coverage mode of a terminal; when the coverage mode is single-layered sub-network coverage, setting a non-ground mobile communication sub-network or a ground mobile communication sub-network corresponding to the single-layered sub-network coverage to be in a standalone operating mode or an intra-layer carrier aggregation mode; and when the coverage mode is multi-layered sub-network coverage, setting the non-ground mobile communication sub-network corresponding to the multi-layered sub-network coverage, or the ground mobile communication sub-network and the non-ground mobile communication sub-network corresponding to the multi-layered sub-network coverage, to be in a cross-layer carrier aggregation mode. The ground mobile communication sub-network and the non-ground mobile communication sub-network use a same or unified radio access technology.
