Solution Overview
Problem
Communication apparatuses supporting multiple operation modes face challenges in transmitting appropriate information about different operation modes to target devices using a first communication system, leading to usability issues.
Innovation Solution
A communication apparatus that uses NFC tags to store and manage communication parameters specific to each operation mode of a wireless LAN, allowing a target device to obtain the necessary information for connecting to the appropriate network mode, enabling seamless switching between AP and STA modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication apparatus supports multiple operation modes and transmits information about all modes using the first communication system, then the target apparatus can obtain information about different operation modes, but the transmitted information may not be appropriate or accurate for the current operation mode
Solution Approach 1:
The patent segments the information transmission by creating separate NFC tags for each operation mode (AP mode and STA mode). Each NFC tag contains only the communication parameters relevant to its specific mode, rather than transmitting all possible mode information. This segmentation ensures that the target apparatus receives accurate, mode-specific information without confusion from irrelevant data about other operation modes.
2Adaptability or versatility
If the communication apparatus transmits communication parameters for all operation modes, then the target apparatus has more information to choose from, but the usability decreases due to information mismatch
Solution Approach 1:
The patent applies preliminary action by pre-configuring separate NFC tags for each operation mode before the handover process. Each NFC tag is prepared in advance with the specific communication parameters needed for its corresponding mode. When the target apparatus connects via NFC, it automatically receives the pre-prepared, appropriate information for the current mode, eliminating the need for post-reception processing or user judgment about which information to use.
3Device complexity
If the communication apparatus uses a single NFC tag for multiple operation modes, then the device complexity is reduced, but the target apparatus cannot obtain mode-specific information
Solution Approach 1:
The patent extracts the communication parameters for each operation mode into separate, independent NFC tags. Instead of including all parameters in a single tag, it takes out only the necessary parameters for each specific mode into dedicated tags. This extraction ensures that each NFC tag contains only relevant information for its corresponding operation mode, allowing the target apparatus to obtain accurate mode-specific information while keeping each individual tag simple and manageable.

AI summary
A communication apparatus supporting multiple operation modes causes a target apparatus to obtain more appropriate information. A communication apparatus is capable of performing wireless communication by using a first communication system and a second communication system. A first operation mode is an operation mode which is used in the second communication system and in which the communication apparatus communicates with a different communication apparatus in a wireless network created by the communication apparatus. A second operation mode is an operation mode which is used in the second communication system and in which the communication apparatus communicates with the different communication apparatus in a wireless network created by an external apparatus. When the first operation mode is selected among the first operation mode and the second operation mode, the storage means stores first information in a storage unit as information to be obtained by the different communication apparatus through the first communication system. The first information is required to establish a connection with the wireless network created by the communication apparatus. When the second operation mode is selected, the storage means stores second information in the storage unit as information to be obtained by the different communication apparatus through the first communication system. The second information is required to establish a connection with the wireless network created by the external apparatus.
