Bluetooth Host Device Automatic Service Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Bluetooth communication technology, external devices operating under a universal HID profile face challenges in providing specialized services due to the need for manual user operation and control, making it difficult to automatically change and provide services.
Innovation Solution
A method and apparatus for Bluetooth communication that involves determining if a connected device is a predetermined profile-based device, transmitting identification information, and controlling the connection based on authentication qualifications to enable automatic service provision and switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external devices use a universal HID profile for Bluetooth communication, then device compatibility and ease of connection are improved, but the ability to provide specialized services is worsened due to manual user operation requirements
Solution Approach 1:
The external device automatically determines its own service type and transmits identification information without requiring manual user configuration. The host device automatically receives and processes this information to establish appropriate connections, enabling self-service operation that eliminates manual user intervention while maintaining compatibility
Solution Approach 2:
The external device performs preliminary actions by pre-configuring its service type and preparing identification information before connection establishment. This preliminary preparation allows the host device to automatically recognize and establish appropriate connections without requiring manual user setup or configuration during the connection process
2Ease of operation
If automatic service provision is implemented, then ease of operation is improved, but device complexity increases due to additional authentication and identification mechanisms
Solution Approach 1:
The patent extracts essential authentication information (service type identification) from the complex Bluetooth connection process and handles it separately through dedicated identification information exchange. This extraction allows automatic service provision while keeping the authentication mechanism modular and manageable, reducing overall system complexity
3Adaptability or versatility
If identification information is transmitted to authenticated devices, then service specialization is improved, but communication overhead increases
Solution Approach 1:
The patent applies partial action by transmitting only the necessary identification information (service type) rather than all possible device parameters. This selective information transmission achieves service specialization while minimizing communication overhead and energy consumption by avoiding unnecessary data exchange

AI summary
A BLUETOOTH communication connection method of a host device communicating with an external device is provided. The method includes determining whether a device to be connected among scanned external devices comprises a predetermined profile based device, and transmitting, by the host device, predetermined identification information to a corresponding connected device when the device to be connected comprises the predetermined profile-based device.
