Dual Network Communication Segmentation for Wireless Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatus configurations face difficulties in establishing wireless communication with mobile terminal devices while maintaining isolation from LAN connections, as both interfaces share the same network segment, making it challenging to enable wireless communication without interfering with LAN communications.
Innovation Solution
An information processing system with a first communication unit connected to a LAN and a second communication unit on a separate network segment, allowing for processing requests from wireless devices to be received and executed independently, using dedicated communication paths to maintain wireless connectivity without compromising LAN communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If both LAN interface and wireless interface are connected to the same network segment, then device complexity is reduced, but wireless communication cannot be established while blocking LAN communication
Solution Approach 1:
The patent divides the communication system into two separate network segments: a first network segment for LAN communication and a second network segment for wireless communication. This segmentation allows independent control of each communication path, enabling wireless communication to be established while blocking LAN communication through the use of separate virtual channels or network interfaces.
2Ease of operation
If wireless communication is enabled on the same network segment as LAN, then ease of operation is improved, but interference with LAN communication occurs
Solution Approach 1:
The patent introduces a communication control mechanism that acts as an intermediary between the wireless interface and the LAN interface. This controller selectively forwards or blocks communication packets between the wireless network segment and the LAN network segment, allowing wireless communication to operate without interfering with LAN communication by filtering and managing traffic flow between the two segments.
3Reliability
If separate network segments are used for LAN and wireless communication, then communication isolation is achieved, but device complexity increases
Solution Approach 1:
The patent implements a communication control unit that can handle multiple communication protocols and functions across different network segments. This multi-functional controller manages both LAN and wireless communication traffic, providing universal communication capabilities that reduce the need for separate dedicated hardware for each network segment, thereby limiting the increase in device complexity.

AI summary
A system according to the present invention includes a first communication unit, a second communication unit, and an executing unit. The first communication unit is connected to a first network segment. The second communication unit is connected to a second network segment different from the first network segment, and receives a processing request, which requests to execute predetermined processing, from an apparatus via the second network segment and transmits the received processing request to the first communication unit. The executing unit executes the predetermined processing in response to the processing request received by the first communication unit.
