Solution Overview
Problem
Conventional techniques face difficulties in avoiding network congestion while maintaining quality of communication service, often leading to deteriorated service for users subjected to band control.
Innovation Solution
A communication control device that includes a first communication unit for wired and second communication unit for wireless networks, an acquisition unit to measure congestion, and a selection unit to switch between networks based on congestion levels, ensuring optimal network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If band control is applied to avoid congestion, then network congestion is reduced, but communication service quality deteriorates
Solution Approach 1:
The system dynamically switches between fixed and mobile communication networks based on real-time congestion conditions. The communication control device monitors congestion levels and automatically selects the most appropriate network, making the system adaptive rather than static. This resolves the contradiction by allowing band control to be applied dynamically only when necessary, rather than continuously degrading service quality.
Solution Approach 2:
The system changes the network parameter (switching between fixed and mobile networks) based on congestion conditions. When the fixed network becomes congested, the system transitions to the mobile network, and vice versa. This parameter change allows the system to avoid congestion while maintaining service quality by selecting the network with better current conditions.
2Object-affected harmful factors
If single network is used for communication, then device complexity is reduced, but ability to avoid congestion is limited
Solution Approach 1:
The communication control device is designed to handle both fixed and mobile network communications through a single unified system. It incorporates multiple communication units (fixed communication unit and mobile communication unit) that can operate independently or in coordination, providing multi-functionality. This allows the system to avoid congestion by selecting between networks while maintaining relatively simple device architecture through integrated control.

AI summary
CPE (10) includes a wired communication unit (11), a wireless communication unit (12), a communication control unit (141), an acquisition unit (142), and a selection unit (143). The wired communication unit (11) relays communication between a housed user device and a fixed communication network. The wireless communication unit (12) relays communication between the user device and a mobile communication network. The acquisition unit (142) acquires the degree of congestion of at least one of the fixed communication network and the mobile communication network. The selection unit (143) selects one of the fixed communication network and the mobile communication network based on the degree of congestion. The communication control unit (141) causes the user device to execute communication by using the communication network selected by the selection unit (143).
