Wireless Device Advertisement Packet Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Bluetooth network environments, accessory devices often broadcast advertisement packets independently, leading to potential overlap and inefficiencies in broadcasting intervals and intensities, which can result in suboptimal advertisement packet delivery to surrounding electronic devices.
Innovation Solution
An electronic device and its counterpart determine a synchronized reference broadcast time point and adjust timing offsets to ensure that their advertisement packets do not overlap, allowing for coordinated and efficient broadcasting based on device-specific information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple accessory devices broadcast advertisement packets independently, then each device can autonomously determine broadcast intervals and intensities, but broadcast packets may overlap causing inefficiency
Solution Approach 1:
Multiple accessory devices merge their broadcast scheduling decisions by establishing a common reference broadcast time point and using timing offsets to coordinate their advertisement packet transmissions, preventing overlaps while maintaining autonomous operation
Solution Approach 2:
Devices perform preliminary synchronization to establish a reference broadcast time point before actual broadcasting occurs, and pre-calculate timing offsets based on device information to ensure non-overlapping transmissions
2Productivity
If devices use synchronized reference broadcast time point with timing offsets, then broadcast packets do not overlap improving delivery efficiency, but coordination complexity increases
Solution Approach 1:
Each accessory device autonomously determines its own timing offset based on its device information without requiring complex negotiation or centralized control, simplifying the coordination mechanism while maintaining synchronization
Solution Approach 2:
The system uses parameter changes in timing offsets and broadcast intervals to achieve coordinated non-overlapping transmissions, adjusting these parameters based on device information to optimize delivery efficiency

AI summary
An electronic device is provided. The electronic device includes a communication module which communicates with a counterpart electronic device through a wireless link, a processor, and a memory in which instructions are stored, wherein the processor is configured to, when the instructions are executed by the processor, identify, based on first device information about the electronic device and second device information from the counterpart electronic device, a first broadcast period of a first advertisement packet and a first timing offset with respect to a reference broadcast time point, and broadcast the first advertisement packet every first transmission period from a time point according to the first timing offset from the reference broadcast time point, wherein the reference broadcast time point is a reference time point synchronized between the electronic device and the counterpart electronic device, and the first timing offset prevents a first broadcast time point of the first advertisement packet from overlapping a second broadcast time point of a second advertisement packet of the counterpart electronic device.
