Multi-Standard Reconnection ID Handling After Registration Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices supporting multiple standards face challenges in determining whether information about an external device is stored, necessitating a new connection request if the information is deleted, and require standard-specific identification procedures for reconnection requests.
Innovation Solution
A communication device with multiple communication circuits and a storage unit that determines registration deletion based on standard-specific identification information obtained through different procedures for each circuit, and outputs a warning if registration is deleted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication device supports multiple communication standards, then it can establish connections with external devices using different standards, but it becomes necessary to perform different determination operations for each standard, increasing operational complexity
Solution Approach 1:
The determination unit is designed to perform multiple functions by automatically selecting the appropriate determination operation based on the communication standard. Instead of requiring separate determination operations for each standard, the system uses a single determination unit that adapts its behavior according to the received reconnection request type (Wi-Fi or Bluetooth), thereby reducing operational complexity while maintaining multi-standard support
Solution Approach 2:
The determination operation dynamically changes based on the communication standard. The determination unit automatically adjusts its determination method according to whether the reconnection request is from Wi-Fi or Bluetooth, making the system flexible and adaptive rather than static and rigid
2Quantity of substance
If information about an external device is deleted, then storage space is freed, but the device cannot execute operations depending on the external device and must transmit a new connection request instead of reconnection request
Solution Approach 1:
The system performs preliminary determination of whether external device information is stored before attempting reconnection. The determination unit checks for the presence of registration information in advance, and only when information is confirmed to be deleted does the system proceed to establish a new connection, avoiding unnecessary reconnection attempts and saving time
3Productivity
If the system checks whether external device information is stored before reconnection, then unnecessary new connection requests are prevented, but the determination process adds operational steps
Solution Approach 1:
The determination operation is merged with the existing reconnection request processing flow. Instead of adding a separate determination step, the system integrates the check for stored information into the reconnection handling process, so that the determination occurs naturally as part of the reconnection workflow without adding significant operational complexity

AI summary
A communication device comprises a first and second communication circuits capable of establishing a connection with an external device conforming to a first and second communication standards, respectively. The device further comprises a storage device stores information about external device(s) registered in an application that uses communication with an external device. The device, when a reconnection request is received from an external device through the first communication circuit or the second communication circuit, outputs a warning if a registration of the external device in the application has been deleted. It is determined whether the registration of the external device in the application has been deleted based on identification information of the external device. The identification information is obtained through different procedures depending on through which of the first and second communication circuits the reconnection request has been received.
