Multi-SIM QoS Selection for Application Data Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices supporting multiple SIMs lack a mechanism to select the SIM that provides the best quality of service (QoS) for specific applications, leading to suboptimal service delivery.
Innovation Solution
An electronic device is configured to store QoS information for each SIM, identify the characteristics of applications, compare the QoS information, and select the appropriate SIM for data transmission and reception based on these characteristics, thereby optimizing service by transmitting a PDU session establishment request message through the selected SIM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device supports multiple SIMs for communication services, then the versatility and communication options are improved, but the complexity of selecting the appropriate SIM for specific applications increases
Solution Approach 1:
The electronic device automatically performs SIM selection based on application characteristics and QoS information without user intervention. The processor autonomously compares QoS parameters, identifies application requirements, and determines the optimal SIM card to use, making the system self-serve the selection task.
Solution Approach 2:
The system changes the parameter of SIM selection by introducing QoS information comparison as the decision criterion. Instead of manual selection or simple round-robin allocation, the selection is dynamically adjusted based on QoS parameters such as data rate, latency, and reliability that match application requirements.
2Reliability
If the electronic device automatically selects SIM based on QoS information, then the service quality is improved, but the processing complexity and computational requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-storing QoS information for each SIM card and pre-identifying application characteristics before actual data transmission. This preparation work is done in advance so that when data needs to be transmitted, the SIM selection can be made quickly based on pre-analyzed information.
Solution Approach 2:
The patent replaces manual SIM selection mechanisms with an automated information processing system. Instead of user-based mechanical selection or simple sequential switching, the system uses processor-based comparison of QoS parameters and application characteristics to intelligently determine the optimal SIM card.
3Measurement precision
If the electronic device stores QoS information for each SIM and compares it for every application, then the accuracy of SIM selection is improved, but the memory usage and processing time increase
Solution Approach 1:
QoS information for each SIM card is stored in advance in the memory, and application characteristics are pre-identified. This preliminary preparation allows the processor to quickly compare pre-stored information rather than gathering and analyzing data in real-time when selection is needed, reducing processing time while maintaining accuracy.
