Solution Overview
Problem
Wireless communication devices connected to multiple networks, such as private and public networks, face challenges in maintaining continuous communication quality, particularly at the cell edge where interference is high and communication speed is affected, leading to unsatisfactory Quality of Service (QoS) during traffic requiring low delay or continuous communication.
Innovation Solution
A wireless communication device with first and second wireless communication units connected to different networks, and a control unit that predicts communication quality and determines whether to switch between networks based on whether the predicted quality meets desired QoS, allowing proactive switching to ensure continuous communication that satisfies the desired quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal device connects to a single network (private or public), then the device complexity is reduced and operation is simpler, but the communication quality cannot be maintained continuously when moving between coverage areas
Solution Approach 1:
The control unit predicts future communication quality before it deteriorates by analyzing current communication state and movement trajectory. When the prediction indicates quality will fall below the threshold, the device proactively switches networks in advance, preventing quality degradation rather than reacting after deterioration occurs.
Solution Approach 2:
The system continuously monitors communication quality metrics (signal strength, interference levels) and feeds this information back to the control unit. This feedback loop enables dynamic adjustment of network selection based on real-time conditions, allowing the device to maintain optimal communication quality by switching networks when necessary.
2Reliability
If a terminal device switches networks reactively when quality deteriorates, then the device complexity remains low, but there is communication quality degradation and delay during the switching process
Solution Approach 1:
The control unit performs predictive analysis of communication quality based on current signal conditions, device movement patterns, and historical data. When the prediction indicates quality will deteriorate below the threshold, the device initiates network switching in advance, ensuring seamless transition without interrupting ongoing communications.
3Reliability
If a terminal device connects to multiple networks simultaneously, then communication quality continuity is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The system dynamically adjusts network connectivity based on predicted communication quality requirements. Instead of maintaining simultaneous connections to multiple networks, the device connects to the optimal single network based on real-time predictions, only establishing additional connections when the current network is predicted to fall below quality thresholds.

AI summary
A wireless communication device (10, 10A) includes a first wireless communication unit (111), a second wireless communication unit (112), and a control unit (130). The first wireless communication unit (111) performs communication by connecting to a first communication network that permits connection in a predetermined area. The second wireless communication unit (112) performs communication by connecting to a second communication network different from the first communication network. The control unit (130) predicts communication quality of communication by the first wireless communication unit (111), and determines whether or not to perform communication by the second wireless communication unit (112) based on whether or not the predicted communication quality satisfies a desired communication quality.
