Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio nodes in fixed networks face challenges with secure and coordinated configuration access, particularly when mobile data transmitting/receiving stations need to influence nodes, due to limited communication bandwidths and the risk of communication errors and data integrity loss from uncoordinated access.
Innovation Solution
The implementation of a combination of radio node-specific tokens and digital twins allows for secure and synchronized access to radio nodes, enabling configuration through mobile data transmitting/receiving stations while preventing misconfigurations and data integrity issues by maintaining a synchronized digital twin of the node's configuration data.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple access methods (fixed base station and mobile data transmitting/receiving station) are allowed for configuring radio nodes, then configuration flexibility and mobility are improved, but communication errors and data integrity loss increase due to uncoordinated access
Solution Approach 1:
The patent introduces a base station as an intermediary coordination entity that manages access to radio nodes. The base station receives configuration requests from mobile data transmitting/receiving stations, coordinates the access timing with the radio node's wake-up schedule, and ensures synchronized configuration updates. This intermediary mechanism enables flexible mobile access while maintaining data integrity through centralized coordination.
Solution Approach 2:
The system implements feedback mechanisms where the radio node reports its current state and configuration to the base station, which then coordinates mobile access requests accordingly. The base station monitors configuration status and provides feedback to mobile stations about optimal access timing, ensuring that configuration operations occur during appropriate wake-up windows and preventing conflicting access attempts.
2Reliability
If configuration access is restricted to fixed base stations only, then data integrity and coordination are maintained, but configuration flexibility and mobile access capability are reduced
Solution Approach 1:
The base station serves as a mediating gateway that enables mobile access without compromising coordination. Mobile data transmitting/receiving stations communicate configuration requests through the base station, which then translates these into properly timed access operations during the radio node's wake-up periods. This allows mobile flexibility while maintaining the coordination benefits of fixed infrastructure.
Solution Approach 2:
The patent adds a temporal dimension to the access coordination by scheduling mobile access requests according to the radio node's wake-up cycle. Instead of restricting access spatially (fixed location only), the system allows mobile access from any location as long as it occurs at the appropriate time dimension (during wake-up windows), thus providing spatial freedom while maintaining temporal coordination.
3Adaptability or versatility
If communication bandwidth is increased to accommodate simultaneous access from multiple stations, then access flexibility is improved, but energy consumption and system complexity increase
Solution Approach 1:
The radio node operates in periodic cycles, alternating between sleep mode and wake-up mode. Configuration access is scheduled to occur only during wake-up periods, allowing the node to remain in low-power sleep mode for the majority of the time. This periodic operation enables the node to handle configuration requests from multiple sources during active periods while minimizing energy consumption during inactive periods.
Solution Approach 2:
The system dynamically adjusts the radio node's operational state based on access requirements. The node transitions between sleep and wake states according to scheduled configuration windows, and the base station coordinates mobile access requests to align with these dynamic state changes. This dynamic operation allows flexible access capability when needed while conserving energy during normal operation.
