Wireless Communication Device BLE to WLAN Switching Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices face inefficiencies when switching from Bluetooth Low Energy (BLE) to wireless LAN connections, as the request source device is not notified when a wireless LAN is generated, leading to prolonged connection times and unnecessary power consumption due to repeated connection requests.
Innovation Solution
A wireless communication device and control method that includes a first wireless communication circuit, a second wireless communication circuit, and a controller, which notifies an external device of network connectivity using the second circuit when a network is generated by the first circuit, and only transmits a join request if the notification is in response to a previous request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the request source device repeatedly transmits connection requests to switch from BLE to wireless LAN, then the connection can be established, but power consumption increases and connection time is prolonged
Solution Approach 1:
The patent implements a feedback mechanism where the wireless LAN access point sends a notification message back to the requesting device through the BLE connection, confirming that the wireless LAN network is ready for connection. This feedback eliminates the need for the requesting device to repeatedly transmit connection requests, thereby reducing power consumption while ensuring reliable connection establishment.
Solution Approach 2:
The patent performs preliminary actions by having the wireless LAN access point generate and prepare the network in advance, then notify the requesting device through BLE. This allows the requesting device to know in advance when the wireless LAN is ready, avoiding unnecessary repeated transmission attempts and reducing both power consumption and connection time.
2Use of energy by moving object
If the request source device waits for a sufficient period before transmitting connection requests, then power consumption is reduced, but connection time is prolonged
Solution Approach 1:
The notification message sent from the wireless LAN access point to the requesting device provides real-time feedback about network readiness. This eliminates the need for the requesting device to wait for an indefinite period, as it can immediately transmit the connection request upon receiving the notification, thus reducing both power consumption and connection time simultaneously.
3Reliability
If the request source device repeatedly transmits connection requests, then connection can be established, but transmission efficiency decreases
Solution Approach 1:
The feedback notification from the wireless LAN access point enables the requesting device to transmit the connection request only once at the appropriate time, rather than repeatedly. This single transmission approach maintains reliable connection establishment while significantly improving transmission efficiency by eliminating redundant requests.
4Device complexity
If the wireless LAN is generated without notifying the request source device, then device complexity is reduced, but information loss occurs
Solution Approach 1:
The patent uses the existing BLE connection as an intermediary channel to transmit the notification message from the wireless LAN access point to the requesting device. This approach does not require additional communication hardware or complex notification mechanisms, yet successfully delivers the network availability information, thus avoiding information loss without increasing device complexity.
