Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiple communication schemes using the same frequency band can lead to interference and degradation of service quality when they do not consider the characteristics of the provided service or connected devices.
Innovation Solution
An electronic device adjusts the sleep times of Bluetooth/BLE communication schemes based on identified frequency bands, device types, priorities, and data requirements to optimize antenna usage and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication schemes simultaneously use the same frequency band, then communication coverage and connectivity are improved, but interference and service quality degradation occur
Solution Approach 1:
The patent implements periodic action by adjusting sleep times of communication schemes in cyclic intervals. The processor dynamically modifies sleep duration based on detected interference levels, creating a rhythmic on-off pattern that allows frequency bands to be shared periodically among multiple communication schemes while reducing continuous interference
Solution Approach 2:
The patent applies dynamics by making sleep time adjustable and adaptive rather than fixed. The processor continuously monitors communication conditions and dynamically modifies sleep parameters in real-time, allowing the system to adapt its frequency band usage based on current interference levels and service requirements
2Reliability
If a specific communication scheme monopolizes the frequency band, then service quality for that scheme is improved, but other communication schemes cannot use the frequency band
Solution Approach 1:
The patent implements dynamic adjustment of sleep times based on priority levels and service requirements. High-priority communication schemes can maintain shorter sleep times or longer active periods, while lower-priority schemes adjust accordingly, allowing flexible frequency band sharing that maintains service quality for critical communications while enabling broader usage
Solution Approach 2:
The patent changes the parameter of sleep time duration based on communication scheme priority and service characteristics. By modifying this temporal parameter dynamically, the system allocates frequency band access in a way that preserves service quality for high-priority schemes while allowing lower-priority schemes to utilize available periods
3Speed
If sleep time is reduced to improve responsiveness, then data transmission capability is improved, but current consumption increases
Solution Approach 1:
The patent optimizes the parameter of sleep time duration based on detected communication conditions and data requirements. When data transmission is urgent or detected, the processor reduces sleep time to improve responsiveness; when transmission is not urgent, it increases sleep time to reduce current consumption, dynamically adjusting this parameter based on real-time needs

AI summary
An electronic device includes: a communication module configured to communicate with a first external device and a second external device; and a processor operatively connected to the communication module. The processor is configured to: identify a first frequency band used for communicating with the first external device; identify a second frequency band used for communicating with the second external device; and based on the first frequency band and the second frequency band at least partially overlapping, adjust a first sleep time of a Bluetooth (BT)/Bluetooth low energy (BLE) communication scheme associated with the first external device.
