Solution Overview
Problem
Wireless communication devices face challenges in maintaining data delivery at a guaranteed rate due to network congestion and varying quality of service, which can disrupt media content streams and other data transmissions.
Innovation Solution
The device employs multiple subscriber identity module (SIM) card information, enabling both best-efforts and quality of service (QoS) data delivery, switching between them based on network quality to ensure continuous data transmission at a reasonable rate by utilizing multiple communication channels and networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If best-efforts data delivery is used to maximize data transmission speed, then productivity is improved, but reliability deteriorates due to network congestion and varying quality of service
Solution Approach 1:
The system dynamically switches between best-efforts data delivery and QoS data delivery modes based on network conditions. The wireless communication device monitors network quality and automatically transitions between delivery mechanisms to maintain both speed and reliability, making the system adaptive rather than static.
Solution Approach 2:
The system changes the delivery parameter from best-efforts to QoS-based transmission when network conditions deteriorate. By adjusting the data delivery mechanism parameter based on monitored network quality metrics, the system optimizes the balance between transmission speed and delivery guarantee.
2Reliability
If QoS data delivery is used to guarantee minimum data rate, then reliability is improved, but productivity decreases due to restricted data transmission speed
Solution Approach 1:
The system dynamically selects between QoS data delivery and best-efforts data delivery based on real-time network conditions. When network quality is good, it uses best-efforts for higher speed; when quality deteriorates, it switches to QoS for guaranteed delivery, making the system adaptive to changing conditions.
Solution Approach 2:
The system adjusts the data delivery parameter between QoS-mode and best-efforts-mode based on monitored network quality. This parameter change allows the system to optimize transmission speed when possible while maintaining delivery guarantees when necessary.
3Adaptability or versatility
If multiple SIM card information are used to enable both best-efforts and QoS data delivery, then adaptability is improved, but device complexity increases
Solution Approach 1:
The wireless communication device is designed with multi-functionality to support both best-efforts data delivery and QoS data delivery through multiple SIM card information. This universal design allows the device to adapt to different network conditions and delivery requirements using a single integrated system.
4Reliability
If automatic switching between best-efforts and QoS data delivery is implemented, then reliability is improved, but ease of operation decreases due to automated control complexity
Solution Approach 1:
The system performs self-service by automatically monitoring network quality and switching between best-efforts and QoS data delivery modes without user intervention. The wireless communication device autonomously manages the complexity of switching control while providing reliable uninterrupted data delivery to the user.

AI summary
A wireless communication device includes a user interface device, a subscriber identity module card slot, a memory, and a processor. The subscriber identity module card slot is configured to receive a subscriber identity module card that includes subscriber identity module card information. The processor is configured to, in response to detection of a subscriber identity module card within the subscriber identify module card slot, present, via the user interface device, an option to store a copy of the subscriber identity module card information to the memory.
