Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-card terminals face resource competition between SIM cards, leading to reduced reliability in service processing due to simultaneous signal reception and transmission limitations.
Innovation Solution
Implement a time-division multiplexing pattern to schedule non-overlapping transmission time windows for each SIM card, allowing separate data processing and reducing resource conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual-card terminal attempts to receive signals from two SIM cards simultaneously, then signal reception capability is improved, but resource competition occurs leading to service execution failure
Solution Approach 1:
The patent segments the time domain into different time windows for different SIM cards. Specifically, it divides the time resources into first time windows for first SIM card and second time windows for second SIM card, allowing each SIM card to have dedicated time slots for signal reception and transmission, thereby avoiding resource competition while maintaining dual-card functionality
Solution Approach 2:
The patent implements periodic time-division multiplexing patterns where time windows for different SIM cards are arranged in a periodic manner. This allows the terminal to cyclically switch between serving different SIM cards with predetermined patterns, ensuring that each SIM card receives periodic access to communication resources without conflict
2Reliability
If dual-card terminal attempts to transmit signals from two SIM cards simultaneously, then transmission capability is improved, but resource competition occurs leading to service execution failure
Solution Approach 1:
The patent segments transmission resources by assigning different time windows to different SIM cards. The first time windows are allocated for first SIM card transmission while second time windows are allocated for second SIM card transmission, preventing simultaneous transmission conflicts and ensuring reliable service execution for both cards
Solution Approach 2:
The patent dynamically adjusts the time window allocations based on service requirements and network conditions. The network device can configure different time-division multiplexing patterns according to actual needs, allowing flexible optimization of transmission capabilities for each SIM card while avoiding resource competition
3Reliability
If time-division multiplexing pattern is implemented to separate transmission time windows, then resource conflicts are prevented, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the terminal reports time-division multiplexing pattern requirements to the network device, and the network device responds with configured patterns. This feedback loop allows the system to adapt to changing conditions while maintaining automated resource allocation, reducing the perceived complexity for users
Solution Approach 2:
The patent enables the terminal to autonomously determine and report its time-division multiplexing pattern needs based on its dual-card configuration and service requirements. The terminal self-manages the scheduling information and coordinates with the network device, reducing the need for complex centralized control
