BLE UWB Hybrid Communication Error Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional Bluetooth Low Energy (BLE) communication systems, a mobile terminal occupies the communication channel until an error is resolved, preventing other users from establishing BLE communication with the information processing apparatus until the error is handled.
Innovation Solution
The system employs Ultra Wide Band (UWB) communication to measure the distance between the information processing apparatus and the mobile terminal, allowing error notifications to be sent via UWB when an error occurs, thereby releasing the BLE channel for other users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing apparatus continues GATT communication with a mobile terminal until error handling is completed, then error notification can be reliably delivered to the user, but the BLE communication channel is continuously occupied and other users cannot establish communication
Solution Approach 1:
The communication system is segmented into two independent channels: BLE for connection establishment and UWB for error notification. By separating these functions, the patent allows BLE to be released for other users while UWB continues to deliver error notifications to the original user, resolving the contradiction between reliable error delivery and communication accessibility.
Solution Approach 2:
UWB communication acts as an intermediary channel between the information processing apparatus and the mobile terminal. Instead of using BLE for both connection and error notification, the patent introduces UWB as a mediator that handles error notifications independently, allowing BLE to be freed for other communication tasks.
2Ease of operation
If the mobile terminal occupies BLE communication until error is resolved, then error can be notified to the user, but other mobile terminals cannot establish BLE communication
Solution Approach 1:
The patent segments the notification function from the connection function by introducing UWB as a separate communication path. This allows the mobile terminal to receive error notifications via UWB without blocking BLE communication, thereby maintaining ease of operation for error notification while improving adaptability for multiple users.
Solution Approach 2:
The patent changes the communication parameter by switching from using a single BLE channel for all communications to using multiple channels (BLE for connection, UWB for notifications). This parameter change enables simultaneous operation for multiple users without compromising error notification reliability.

AI summary
An information processing apparatus that prevents one mobile terminal from occupying BLE communication until completing error handling. The information processing apparatus executes a predetermined process based on data received from a mobile terminal and includes a function to obtain information from the mobile terminal by first wireless communication after establishing communication connection with the mobile terminal, the information being necessary for second wireless communication different from the first wireless communication, a function to disconnect the communication connection by the first wireless communication and to establish communication connection by the second wireless communication in response to obtainment of the information, a function to measure a distance between the information processing apparatus and the mobile terminal by the second wireless communication, and a function to notify of, when an error relating to the predetermined process occurs, the error by a method other than the first wireless communication based on the measured distance.
