Wireless Communication Device with Application-Specific Connection Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face issues with erroneous connections to unintended devices due to the termination of advertising packets based on incorrect advertising identifiers, leading to the loss of connection opportunities with intended partners.
Innovation Solution
The device sets a different advertising identifier for each application, repeatedly transmits advertising packets without the identifier, receives connection requests, terminates the previous packet transmission, and determines if the connection is intended, allowing for correct wireless connection to the expected device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the advertising packet transmission is terminated based on receiving a connection request, then the connection establishment speed is improved, but the reliability of connecting to the intended device deteriorates due to erroneous connections
Solution Approach 1:
The patent applies preliminary action by verifying device identity through advertising identifier matching before finalizing the connection. The control circuit checks whether the advertising identifier in the connection request matches the expected advertising identifier for the target application, preventing erroneous connections before they occur. This preliminary verification step ensures reliable connection establishment without sacrificing speed.
2Use of energy by moving object
If the advertising packet transmission is terminated immediately upon receiving a connection request, then the energy consumption is reduced, but the loss of connection opportunities with intended partners increases
Solution Approach 1:
The patent implements feedback by continuously monitoring whether the received connection request corresponds to the expected advertising identifier. The control circuit uses this feedback to determine whether to terminate advertising packet transmission or maintain it. This feedback mechanism ensures that advertising transmission is only terminated when a valid, intended connection is detected, preventing loss of connection opportunities while still reducing energy consumption when appropriate.

AI summary
A wireless communication device includes a communication unit and a control circuit for controlling the communication unit. The control circuit sets, in the communication unit, a different advertising identifier for each application. The communication unit repeatedly transmits an advertising packet that corresponds to the set advertising identifier and does not include the advertising identifier, receives a connection request for wireless communication transmitted from a first wireless communication device that is one of the other wireless communication devices that have received the advertising packet, terminates transmission of the advertising packet transmitted immediately before the connection request is received, and wirelessly connects to the first wireless communication device. The control circuit determines whether the wirelessly connected first wireless communication device is a connection destination expected by a first advertising identifier being the advertising identifier corresponding to the advertising packet whose transmission is terminated.
