Bluetooth Link Authority Handover for Mesh Network Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices connected via Bluetooth often require disconnecting from one device to connect to another, and in Bluetooth mesh networks, temporary communication failures can disrupt data transmission between devices, necessitating manual reconnection procedures.
Innovation Solution
An electronic device with a processor, memory, and wireless communication circuitry can share link authority, allowing seamless handover of connections and data transmission without requiring explicit reconnection procedures by transmitting link information and channel hopping data to adjacent devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an electronic device supports only a specific profile connection, then the connection stability is improved, but the adaptability to connect to multiple different devices deteriorates
Solution Approach 1:
The electronic device is designed to support multiple Bluetooth profiles (audio, data, control) within a single connection framework, allowing it to adapt to different device types while maintaining stable connections through standardized link authority management
2Adaptability or versatility
If the electronic device establishes a new connection, then the adaptability to connect to different devices is improved, but the loss of time for disconnection and reconnection deteriorates
Solution Approach 1:
The device performs preliminary actions by maintaining link authority information and connection parameters in memory before actual connection switching is needed, allowing rapid handover to new devices without full reconnection procedures
Solution Approach 2:
The link authority mechanism enables continuous data transmission during connection handover by maintaining active communication channels and transferring authority seamlessly, preventing interruption of useful actions
3Adaptability or versatility
If the electronic device supports multiple connections, then the adaptability to connect to multiple devices is improved, but the device complexity increases
Solution Approach 1:
The connection management is segmented into distinct profiles (audio, data, control) with dedicated handling routines, allowing multiple connections to be managed through modular, organized structures rather than monolithic complexity
4Ease of operation
If manual reconnection procedure is performed, then the ease of operation is maintained, but the productivity for data transmission deteriorates
Solution Approach 1:
The link authority mechanism enables automatic connection management and handover without requiring user intervention, with the system self-managing connection transitions while maintaining user-initiated control when needed

AI summary
An electronic device including a user interface, at least one wireless communication circuit, a processor, and a memory connected to the processor. The memory may store instructions that, when executed, cause the processor to transmit and/or receive data to and/or from a first external electronic device through the wireless communication circuit, to search for a second external electronic device positioned at a periphery of the electronic device, to transmit at least part of connection information with the first external electronic device to the second external electronic device, and to receive data from the first external electronic device and/or the second external electronic device based on a user input via the user interface, an occurrence of an event at the electronic device, a request of the first external electronic device, or an occurrence of an event at the first external electronic device.
