Central Priority Advertisement Packet for BLE Connection Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The central/peripheral relationship established between medical devices and patient's mobile devices via Bluetooth Low Energy (BLE) prevents healthcare providers from connecting with medical devices when the patient's mobile device is nearby, hindering data extraction.
Innovation Solution
Broadcasting a 'central priority' advertisement packet by the healthcare provider's device causes the patient's mobile device to temporarily discontinue its connection with the medical device, allowing the healthcare provider's device to establish communication with the medical device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patient's mobile device maintains a central/peripheral relationship with the medical device, then continuous data tracking and reporting is improved, but healthcare provider connection and data extraction are prevented
Solution Approach 1:
The system dynamically changes the connection state by transitioning the mobile device from a connected central device to a disconnected state during healthcare provider interactions. The mobile device can switch between maintaining continuous connection for data tracking and disconnecting to allow provider access, making the connection behavior adaptive rather than static
Solution Approach 2:
The mobile device proactively disconnects or suspends its connection to the medical device before the healthcare provider attempts to connect, preventing connection conflicts. This preliminary action ensures the provider can establish communication without interference from the patient's device
2Loss of information
If the patient's mobile device continuously connects to the medical device for data monitoring, then patient data tracking is improved, but device availability for healthcare providers deteriorates
Solution Approach 1:
The mobile device employs periodic connection and disconnection cycles, maintaining connection during normal patient monitoring periods and suspending connection during scheduled healthcare provider visits. This periodic action allows both continuous data tracking over time and periodic provider access without conflict
3Ease of operation
If Bluetooth Low Energy creates a central/peripheral relationship between mobile device and medical device, then wireless data communication is improved, but connection exclusivity prevents multi-device communication
Solution Approach 1:
The mobile device temporarily extracts itself from the central/peripheral relationship by disconnecting or suspending its connection to the medical device. This allows the healthcare provider's device to establish a new central/peripheral relationship with the medical device without interference from the patient's mobile device

AI summary
Techniques are disclosed for enabling a first central device to connect with a medical device with an existing connection to a second central device by broadcasting a "central priority" advertisement packet that causes the second central device to discontinue attempts to connect with the medical device (for a period of time), granting the first central device the ability to establish communication with the medical device.
