Engineering Contradiction Analysis
1Use of energy by moving object
If ultra-low power IoT devices are used to reduce power consumption, then power consumption is reduced, but connection reliability deteriorates due to device movement and lack of battery management
Solution Approach 1:
The patent introduces a base station as an intermediary that manages ultra-low power IoT devices. The base station monitors communication states and signal reception quality, and can switch connection targets when devices move, thereby maintaining connection reliability without requiring the IoT device itself to have active management capabilities.
Solution Approach 2:
The system implements feedback mechanisms where the base station continuously monitors communication state information and signal reception quality from ultra-low power IoT devices. Based on this feedback, the base station determines whether to switch connection targets, ensuring reliable communication despite device movement.
2Reliability
If connection switching is implemented to maintain connectivity for moving devices, then connection reliability is improved, but system complexity increases
Solution Approach 1:
The base station serves as a mediator that centralizes the complexity of connection management. Instead of requiring complex switching logic in each ultra-low power IoT device, the base station handles all monitoring and switching decisions, simplifying the overall system architecture while maintaining reliability.
Solution Approach 2:
The ultra-low power IoT devices operate in a self-service mode where they simply transmit and receive signals without active connection management. The base station autonomously monitors communication states and performs switching operations, allowing the IoT devices to remain in low-power states while the system maintains reliability.

AI summary
A communication system includes a base station configured to be compatible with a 5th generation radio access system, a communication terminal configured to be connected to the base station, and a device configured to be connected to the base station or the communication terminal, in which, in a state where the device is connected to the communication terminal, the base station acquires information on a state of communication between the communication terminal and the device and information on a state of reception of a signal transmitted by the device at another communication terminal different from the communication terminal, determines whether or not it is necessary to switch a destination communication terminal to which the device is connected, based on one or both of the acquired information on the state of communication and the acquired information on the state of reception, and determines a switching target communication terminal when it is necessary to switch the destination communication terminal to which the device is connected.
