Bluetooth Object Transfer Service for Bulk Data Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) technology faces limitations in transferring data larger than 512 bytes, requiring object-based methods and lacking clear notification mechanisms for data changes, which increases server and client load and power consumption.
Innovation Solution
A method for managing and transferring object-type data in BLE technology through object transfer services, including advertising messages, scan responses, connection requests, and object action control points to manage object operations, permissions, and notifications, allowing for efficient data transfer and reduced load by clearly identifying created or changed data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If object-based transfer method is used to overcome 512 byte limit, then data transfer capability is improved, but notification mechanism complexity increases
Solution Approach 1:
The patent introduces an object transfer service layer as an intermediary between the data transfer mechanism and the notification mechanism. This service layer manages object identifiers and coordinates notifications across multiple devices, simplifying the overall system complexity while enabling bulk data transfer through structured object-based methods
2Reliability
If clear notification of data changes is implemented, then data management reliability is improved, but communication overhead increases
Solution Approach 1:
The patent extracts the notification function into separate notification messages that are independently managed from the data transfer process. By using distinct notification mechanisms with object identifiers, the system achieves reliable data change notification while minimizing communication overhead through targeted, efficient messaging
Solution Approach 2:
The patent changes the parameter of notification from generic data change alerts to specific object-identifier-based notifications. This parameter change enables precise targeting of notifications, reducing unnecessary communication while maintaining reliability through explicit object reference tracking
3Productivity
If object transfer service is implemented, then data transfer efficiency is improved, but device load increases
Solution Approach 1:
The patent segments the data transfer process into managed object units with identifiers, allowing efficient bulk transfer through structured handling. By dividing data into manageable objects with metadata, the system achieves high transfer efficiency while reducing device load through organized, modular processing

AI summary
Disclosed is a method for performing communication using Bluetooth in a wireless communication system. The method includes sending an advertising message providing notification of the provision of an object transfer service to a first client device, receiving a scan request message for requesting additional information from the first client device, sending a scan response message to the first client device in response to the scan request, receiving a connection request message for Bluetooth connection from the first client device, selecting a specific object as a current object, and receiving control information indicating whether the execution of a specific operation in the selected current object is permitted from the first client device.
