Smartphone Bluetooth Handover Control for Multiple Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple digital cameras connected via Bluetooth Low Energy to a smartphone attempt to handover to Bluetooth Classic simultaneously, at least one camera fails to establish the handover, leading to potential failures in data transfer processes.
Innovation Solution
An information processing apparatus with a first wireless communication unit for simultaneous communication with multiple devices and a second unit for selective communication with one device, along with a control unit that manages connections and notifies devices about allowed transitions to Bluetooth Classic, ensuring only one camera can handover to Bluetooth Classic at a time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple digital cameras attempt to handover to Bluetooth Classic simultaneously, then the communicable range and connection flexibility are improved, but the handover success rate deteriorates due to congestion and resource conflicts
Solution Approach 1:
The notification unit sends notifications to other digital cameras about the handover request before the handover is executed. This preliminary action allows other cameras to know in advance that a handover is occurring, so they can refrain from initiating simultaneous handovers, thereby preventing congestion and ensuring handover success.
Solution Approach 2:
The system implements a feedback mechanism where the smartphone sends notifications back to other digital cameras regarding the handover status. This feedback loop allows the system to coordinate handover actions across multiple devices, ensuring that only one camera attempts to handover at a time, thus resolving the contradiction between connection flexibility and handover reliability.
2Productivity
If the smartphone allows multiple digital cameras to establish Bluetooth Classic connections simultaneously, then the data transfer capacity is improved, but the communication stability deteriorates due to resource conflicts
Solution Approach 1:
Before establishing a Bluetooth Classic connection, the smartphone sends a notification to other connected digital cameras via Bluetooth Low Energy. This preliminary notification prevents other cameras from initiating simultaneous connection requests, thereby avoiding resource conflicts and maintaining communication stability while still allowing multiple cameras to transfer data sequentially.
3Loss of time
If the handover processing is performed without notification to other devices, then the handover speed is improved, but the handover reliability deteriorates due to simultaneous requests from multiple cameras
Solution Approach 1:
The notification is sent in advance during the handover process, allowing other digital cameras to adjust their behavior before the actual handover occurs. This preliminary notification maintains fast handover execution while preventing simultaneous handover attempts from multiple cameras, thus resolving the contradiction between handover speed and reliability.

AI summary
An information processing apparatus includes a first wireless communication unit that performs wireless communication with a plurality of communication apparatuses simultaneously, a second wireless communication unit that performs wireless communication with one of the plurality of communication apparatuses selectively, a control unit that controls establishment of a wireless connection with one of the plurality of communication apparatuses via the second wireless communication unit based on information shared via the first wireless communication unit, and a transmission unit that transmits, in a case a request to establish a wireless connection via the second wireless communication unit is received from one of the plurality of communication apparatuses, a notification indicating that a connection via the second wireless communication unit is not allowed to a communication apparatus that has a wireless connection to the information processing apparatus via the first wireless communication unit, and is not a transmitter of the request.
