Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed base stations are used to provide communication services, then communication reliability is improved in normal conditions, but communication service availability deteriorates in regions with limited or damaged infrastructure
Solution Approach 1:
The patent introduces mobile cells (drones) that can dynamically relocate to provide communication services. Unlike fixed base stations, these mobile cells can move horizontally and vertically to reach disaster zones or remote areas, transforming the static communication infrastructure into a dynamic system that adapts to changing environmental conditions and infrastructure availability.
Solution Approach 2:
The mobile cell acts as an intermediary between the core network and user equipment in challenging environments. It receives data from the core network and relays it to destination nodes, or collects data from source nodes and forwards it to the core network, enabling communication where direct connectivity is not possible.
2Area of stationary object
If mobile cells are deployed to reach remote or disaster zones, then service coverage is improved, but path loss increases due to distance and environmental obstacles
Solution Approach 1:
The patent utilizes the vertical dimension by enabling mobile cells to fly at different altitudes. This three-dimensional mobility allows the system to overcome ground-based obstacles such as buildings, terrain, and disaster debris by positioning the communication node in the air, thereby reducing path loss while maintaining or expanding service coverage area.
Solution Approach 2:
The system dynamically adjusts operational parameters including altitude, horizontal position, and orientation of mobile cells based on real-time channel status information. By changing these parameters, the system optimizes the balance between coverage area and path loss, selecting positions that minimize signal attenuation while maximizing service availability.
3Productivity
If mobile cells dynamically reposition to optimize communication, then path loss is minimized and communication capacity is maximized, but system complexity increases due to positioning and coordination requirements
Solution Approach 1:
The system implements feedback mechanisms where mobile cells continuously acquire channel status information from source and destination nodes, and this information is used to determine optimal positioning. The cost function or pathloss model processes this feedback to identify positions that maximize communication capacity, creating a closed-loop control system that adapts to changing conditions while managing complexity through systematic decision-making.
4Adaptability or versatility
If mobile cells are used in regions with damaged infrastructure, then communication service accessibility is improved, but energy consumption increases due to mobility and relay operations
Solution Approach 1:
The system employs partial mobility where mobile cells remain stationary once positioned at optimal locations for extended periods, rather than continuously moving. This reduces energy consumption associated with constant motion while maintaining the ability to relocate when needed. The system performs mobility actions only when necessary to improve service accessibility, balancing energy usage with service availability.

AI summary
To achieve the above described objective, a disclosure of the present specification provides a method in which a cell having mobility provides a communication service. The method may comprise the steps of: obtaining, by the cell having mobility, first channel state information associated with a departure point node that is to transmit data; obtaining, by the cell having mobility, second channel state information associated with a destination node that is to receive data; and determining, by the cell having mobility, a location where the cell is to be located at a time point for data communication relay between the departure point node and the destination node on the basis of the first channel state information and the second channel state information. In this instance, the cell having mobility can move in the horizontal direction and the vertical direction from the surface of the earth.
