Engineering Contradiction Analysis
1Speed
If wireless communication systems are used to provide high-quality wireless networks with large capacity and low latency, then communication speed and capacity are improved, but reliability deteriorates due to fluctuations in radio wave strength caused by terrain and object interference
Solution Approach 1:
The system dynamically switches between different communication systems (wireless and wired) based on real-time communication environment conditions and application requirements. The communication control device monitors radio wave strength fluctuations and terrain conditions, then adaptively selects the most reliable communication path, transforming the static communication system into a dynamic one that responds to environmental changes.
Solution Approach 2:
The invention changes the communication mode parameter from fixed wireless to variable (wireless/wired switching). By monitoring communication quality parameters such as radio wave strength and terrain conditions, the system adjusts the communication mode parameter to maintain high reliability while preserving high speed capabilities when conditions permit.
2Reliability
If communication paths are switched adaptively depending on communication environment, then communication quality is improved, but device complexity increases due to multiple communication systems and switching mechanisms
Solution Approach 1:
The invention introduces a communication control device as an intermediary between applications and communication systems. This mediator handles the complexity of monitoring communication environments, evaluating multiple communication paths, and making switching decisions, thereby isolating the complexity from the core communication functions and applications while maintaining high communication quality.
Solution Approach 2:
The communication control device performs multiple functions including monitoring communication environment conditions, evaluating different communication paths, making switching decisions, and managing application requirements. By consolidating these diverse functions into a single multi-functional device, the system achieves high communication quality without proportionally increasing overall system complexity.
3Adaptability or versatility
If communication requirements are adjusted for each application operation, then adaptability is improved, but control complexity increases due to need to detect and respond to application operation changes
Solution Approach 1:
The system implements feedback mechanisms where the communication control device continuously monitors application operation states and communication environment conditions. Based on this feedback, the device automatically adjusts communication path selections and parameters to match current application requirements, enabling high adaptability through automated closed-loop control rather than manual configuration.
Solution Approach 2:
The communication control device autonomously detects application operation changes and self-adjusts communication paths without requiring external intervention. The system serves itself by monitoring its own communication environment and application states, then automatically making control decisions to maintain optimal communication performance across varying operational conditions.

AI summary
To determine a communication path satisfying communication requirements depending on an operation of an application, it is provided a management device for selecting a communication path that satisfies communication requirements for an application operating on a terminal, the management device comprising: an event detection module configured to detect, as an event, one of an operation change, an increase, or a decrease of the application which is accompanied by a change in the communication requirements; app information for managing the communication requirements for each operation of the application; communication path information for managing communication quality of each communication path; and a communication control method calculation module configured to determine, by referring to the app information and the communication path information, a communication control method that satisfies the communication requirements for the application from which the event has been detected, and notify a communication control device of the determined communication control method.
