Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Classic audio consumes high power and has limitations on the number of connectable devices, while LE audio supports multi-stream functionality but lacks efficient management of overlapping audio service time resources.
Innovation Solution
An electronic device determines and sets non-overlapping time resources for multiple audio services, adjusting quality or priorities when necessary, to manage LE audio services effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Bluetooth Classic audio is used, then audio quality is maintained, but power consumption increases and the number of connectable devices is limited
Solution Approach 1:
The patent segments audio services into multiple streams, where each stream can be independently managed with its own time resources. This allows the system to handle multiple LE audio connections simultaneously by dividing the audio transmission into separate, manageable segments, thereby increasing the number of connectable devices while maintaining low power consumption.
Solution Approach 2:
The patent implements dynamic time resource allocation for audio services, where time resources are adjusted based on service priorities and overlapping conditions. This dynamic management enables the system to adaptively handle multiple audio streams, improving device connectivity while optimizing power usage through flexible resource scheduling.
2Adaptability or versatility
If multiple audio services are provided simultaneously, then service versatility is improved, but time resource management complexity increases due to overlapping resources
Solution Approach 1:
The patent performs preliminary determination of time resource overlaps before providing multiple audio services. By checking for overlapping time resources in advance and adjusting them proactively, the system avoids the complexity of managing conflicts during service execution, thereby enabling versatile multi-service operation with simplified resource management.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors time resource allocation for multiple audio services and adjusts allocations based on detected overlaps. This feedback-driven approach maintains service versatility while managing time resource complexity through real-time optimization and conflict resolution.
3Reliability
If time resources for multiple audio services are set to avoid overlap, then service reliability is improved, but time resource utilization efficiency decreases
Solution Approach 1:
The patent changes the parameter of time resource allocation by introducing priority-based overlapping, where higher-priority services can utilize time resources even when overlaps occur. This parameter change allows the system to maintain service reliability for critical functions while improving overall time resource utilization efficiency through controlled overlaps of lower-priority services.
4Reliability
If quality adjustment is performed when time resources overlap, then service reliability is maintained, but system complexity increases
Solution Approach 1:
The patent applies local quality adjustment by modifying audio service quality parameters specifically in overlapping time resource regions, rather than uniformly across all services. This localized approach maintains service reliability for non-overlapping portions while managing overlaps through quality adjustments, thereby reducing overall system complexity compared to global quality management.

AI summary
A method for providing audio according to an embodiment may comprise the steps of: determining whether a second time resource for performing a second audio service can be configured to not overlap with a first time resource configured for a first audio service being performed by an electronic device; configuring the second time resource so that at least a portion of the first time resource and at least a portion of the second time resource overlap when it is determined that the first time resource and the second time resource cannot be configured to not overlap; and performing the second audio service on the basis of the second time resource.
