BLE Object Transfer Service for Bulk Data Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) technology lacks a clear method for managing and transmitting object-related data, particularly for bulk data transmission, object creation, changes, and event timing, which results in inefficiencies and increased power consumption.
Innovation Solution
A method is provided for BLE communication systems that includes object transfer services, where a client device receives advertising messages from a server device, establishes a connection, and manages object data by transmitting object identification information, generation flags, and event generation times, allowing for efficient filtering and updating of object lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional BLE characteristic data transmission is used, then data can be transmitted, but bulk data transmission is inefficient and power is wasted
Solution Approach 1:
The patent segments data transmission into object-based units with identification information, allowing selective notification of changed objects rather than transmitting all data. This enables efficient bulk data transmission by only sending changes, reducing both transmission time and power consumption.
Solution Approach 2:
The server device preliminarily manages object identification information and change detection before transmission. When data changes occur, the server prepares and transmits only the necessary object identification information and change details, avoiding unnecessary data transmission and reducing power consumption.
2Ease of operation
If clear object change notification method is implemented, then data management is improved, but transmission overhead increases
Solution Approach 1:
The patent extracts only the essential information needed for object change notification - object identification information and change details - from the complete data set. This allows clear object change notification while minimizing transmission overhead by excluding unnecessary data.
Solution Approach 2:
The server device acts as an intermediary that manages object identification information and handles the notification process. It filters and prepares only the necessary change information to transmit to client devices, reducing data volume while maintaining clear object change notification capability.
3Reliability
If comprehensive object search is performed, then data completeness is ensured, but search time and processing load increase
Solution Approach 1:
The server device provides feedback to client devices about object changes through identification information and change notifications. This feedback mechanism eliminates the need for client devices to perform comprehensive searches, as they receive direct notifications about changed objects, reducing search time while ensuring data completeness.
Solution Approach 2:
The server device preliminarily tracks and manages object identification information, preparing change notifications before they are needed. This preliminary action eliminates the need for time-consuming searches at the client device, as all necessary object change information is already prepared and can be transmitted immediately.

AI summary
Disclosed herein is a method for performing communication using Bluetooth low energy (BLE) in a wireless communication system including a server device and a client device. The client device receives object changed indication information including object identification information indicative of a changed object from the server device. The object identification information includes the name of the changed object or the identifier (ID) of the changed object.
