Address Book Management for P2P Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatuses supporting peer-to-peer (P2P) connections lack efficient methods for automatically registering and managing connected wireless devices in their address books, particularly in terms of secure and convenient user authentication, connection control, and security management.
Innovation Solution
The method involves the image forming apparatus operating as a soft access point to connect with external wireless devices via a wireless local area network (WLAN), allocating an IP address through a DHCP server, and registering the connected devices in an address book with generated names using device information, while also scanning for supported protocols and updating the address book upon connection or disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic registration of wireless devices is implemented, then user convenience is improved, but device complexity increases
Solution Approach 1:
The system automatically registers wireless devices by detecting their connection status and extracting device information without requiring manual user input. The address book management unit autonomously performs registration, updates, and maintenance operations, allowing the system to serve itself rather than requiring user intervention for each registration task.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the address book management unit to automatically detect, extract, and register device information before the user needs to use the device. Connection status detection and device information extraction are performed in advance, so when the user connects a wireless device, the registration is already handled automatically without requiring manual configuration.
2Productivity
If manual device information entry is required, then device complexity is reduced, but connection speed decreases
Solution Approach 1:
The patent replaces the mechanical/manual process of typing or entering device information with an automated information extraction mechanism. The system automatically extracts device information from the connected wireless device's identification data, eliminating the need for manual entry while reducing the complexity of implementing automated extraction compared to manual processes.
Solution Approach 2:
The system creates a copy of the device information directly from the wireless device's identification data and stores it in the address book. Instead of requiring the user to manually input information, the system copies the essential device identifiers and information automatically, significantly speeding up the connection process while maintaining accurate device records.
3Reliability
If comprehensive security management is implemented, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The address book management unit autonomously manages security by automatically detecting connection status, extracting device information, and maintaining the address book without requiring user intervention. The system performs security-related tasks such as connection monitoring and data management independently, reducing the operational burden on users while maintaining comprehensive security controls.
Solution Approach 2:
The system implements feedback mechanisms where the address book management unit continuously monitors connection status and automatically updates the address book based on detected changes. When devices connect or disconnect, the system receives feedback about the connection state and automatically adjusts the address book accordingly, maintaining security without requiring manual user actions.

AI summary
A method of managing an address book of an image forming apparatus that supports a peer-to-peer (P2P) connection includes connecting the image forming apparatus to an external wireless device in the P2P connection method through a wireless local area network (WLAN); operating a soft access point (AP) module of the image forming apparatus so that the image forming apparatus operates as an AP; allocating an internet protocol (IP) address to the wireless device by driving a dynamic host configuration protocol (DHCP) server unit (DHCP server) of the image forming apparatus; and registering the wireless device connected to the image forming apparatus in the address book, which stores wireless devices that are connectable to the image forming apparatus, with the allocated IP address.
