Bluetooth LE Notification Filtering for Peripheral Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing Bluetooth wireless communication technology, frequent pop-up notifications for connecting peripheral devices to main smart devices cause user inconvenience, especially as the number of peripheral devices increases.
Innovation Solution
A method for efficient Bluetooth pairing and notification is introduced, which involves redefining information in advertising messages, applying different scan windows based on device priority, and transmitting notification messages according to content filtering, allowing for adaptive priority allocation and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection notifications are displayed for all peripheral devices, then device discovery completeness is improved, but user convenience deteriorates due to frequent pop-up notifications
Solution Approach 1:
The patent applies local quality by differentiating the treatment of peripheral devices based on their content types. Audio devices, video devices, and other devices are handled differently in terms of notification display. This allows the system to provide customized notification behavior for different device categories, improving user convenience while maintaining complete device discovery.
2Reliability
If scanning is performed for all adjacent devices, then device discovery completeness is improved, but power consumption increases
Solution Approach 1:
The patent implements local quality by applying different scan window configurations to different peripheral devices based on their content types and priorities. High-priority devices receive more scanning resources while low-priority devices receive reduced scanning, thereby maintaining discovery completeness for important devices while reducing overall power consumption.
Solution Approach 2:
The patent applies partial action by performing scanning operations selectively rather than uniformly for all devices. The scan window is adjusted to provide partial scanning for less important devices and more comprehensive scanning for important devices, optimizing the balance between discovery completeness and power consumption.
3Adaptability or versatility
If connection management is performed for all peripheral devices, then device compatibility is improved, but device complexity increases
Solution Approach 1:
The patent reduces complexity by applying local quality to connection management. Different connection management strategies are applied to different device types (audio, video, other). This allows the system to handle diverse device categories with specialized management approaches rather than using a single complex management mechanism for all devices.

AI summary
The present invention relates to a method and an apparatus for connecting adjacent devices using Bluetooth Low Energy (LE). In particular, a method performed in a first device comprises the steps of: receiving an advertisement message from at least one adjacent device, wherein the advertisement message includes information on a content type supported by the at least one adjacent device; transmitting, to the at least one adjacent device, a notification message for notifying a pop-up for a user of the first device on the basis of the advertisement message; and transmitting a connection request message for requesting connection to the at least one adjacent device according to an input of the user.
