NFC Tag Connection Management for Multi-Access Point Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals are unable to handle multiple pieces of connection information obtained through near field communication (NFC), limiting their ability to establish wireless communication with multiple access points, such as those found in office environments.
Innovation Solution
An information processing apparatus equipped with an acquisition unit to obtain connection information from an NFC tag, a determination unit to identify multiple pieces of information, a display unit to present a selection screen for user choice, and a wireless communication unit to establish communication based on selected information, allowing users to select or automatically choose the appropriate connection for handover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional NFC tag stores a single piece of connection information, then the device complexity is low, but the adaptability to multiple access points is limited
Solution Approach 1:
The patent segments the connection information storage by organizing multiple access point connection information into a structured list format within the NFC tag. Each access point's connection information is separated into individual entries, allowing the terminal to obtain and process multiple distinct connection information sets without overwhelming complexity
Solution Approach 2:
The patent implements preliminary action by having the terminal obtain and store multiple access point connection information in advance within the NFC tag before actual wireless communication is needed. This pre-prepared list of connection information allows for quick selection and connection without real-time complexity when the user needs to connect to different access points
2Adaptability or versatility
If the portable terminal obtains multiple pieces of connection information from NFC, then the adaptability to different environments is improved, but the ease of operation deteriorates due to lack of appropriate processing
Solution Approach 1:
The patent implements self-service by enabling the terminal to automatically process multiple connection information obtained from NFC. The terminal autonomously manages the list of connection information, performs automatic selection based on connection status, and handles the complexity of multiple access points without requiring user intervention, thus maintaining ease of operation while improving adaptability
3Productivity
If a single connection information is stored in NFC tag, then the loss of information is minimal, but the productivity in office environments with multiple access points is reduced
Solution Approach 1:
The patent applies the nesting principle by organizing multiple access point connection information within a hierarchical structure in the NFC tag. The connection information is nested in a list format where multiple access point entries are contained within a single NFC tag data structure, allowing efficient storage and retrieval of multiple connection information sets without excessive information loss

AI summary
If an information processing apparatus obtains a plurality of pieces of connection from a near field communication tag, the information processing apparatus displays a selection screen via which a piece of connection information is selected from among the plurality of pieces of connection information. If a piece of connection information is selected, the information processing apparatus establishes wireless communication based on the selected connection information.
