Communication Device Link Mode Selection for MFP Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems involving Multi-Function Peripherals (MFPs), the establishment of specific communication links with mobile terminals or IC cards is inconsistent, leading to failures in performing intended functions when the wrong communication link is established.
Innovation Solution
A communication device equipped with a wireless interface and processor, capable of determining the type of communication partner through attribute information in received signals, and switching between Peer to Peer (P2P) and Reader-Card Emulation (CE) modes to ensure appropriate authentication and function execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device attempts to establish a P2P communication link with a mobile terminal, then the function compliance with mobile terminal instructions is improved, but the system fails when a Reader-CE link is established instead, leading to inability to perform intended functions
Solution Approach 1:
The communication device performs preliminary determination of the target device type using attribute information from the specific signal before establishing the communication link. This allows the device to pre-select the appropriate communication mode (P2P or Reader-CE) based on whether the target is a mobile terminal or IC card, preventing subsequent function execution failures.
Solution Approach 2:
The communication device dynamically switches between P2P mode and Reader-CE mode based on the determined target device type. The system adapts its communication link establishment strategy in real-time according to the target device attributes, ensuring the correct communication protocol is used for each device type.
2Reliability
If the communication device executes authentication process for all connected devices, then security is improved, but unnecessary authentication delays occur when the target is a mobile terminal using P2P communication
Solution Approach 1:
The communication device performs preliminary determination of the target device type before initiating authentication. By identifying whether the target is a mobile terminal or IC card in advance using attribute information, the device can conditionally execute authentication only when necessary (for IC cards), avoiding unnecessary authentication delays for mobile terminals.
3Ease of operation
If the communication device establishes Reader-CE link with a mobile terminal, then communication link establishment is improved, but the intended P2P communication function cannot be performed
Solution Approach 1:
The communication device performs preliminary determination of the target device type using attribute information from the specific signal before establishing the communication link. This allows the device to pre-select the appropriate communication mode (P2P or Reader-CE) based on whether the target is a mobile terminal or IC card, preventing subsequent function execution failures.

AI summary
A communication device may perform a predetermined communication using a first type communication link via a wireless interface with the target device being a first type device, determine, by using attribute information, which of the first type device or a second type device the target device is, execute an authentication of the target device being the second type device, disconnect the second type communication link without executing an authentication of the target device in a case where it is determined that the target device is the first type device, and perform the predetermined communication using the first type communication link via the wireless interface with the target device being the first type device in a case where the first type communication link is established between the communication device and the target device being the first type device after the second type communication link has been disconnected.
