Transceiver Coordinator for Dual-SIM Data Rate Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-card or multiple-card cellular phones face performance degradation in packet-switched data services due to the lack of coordination between wireless communication modules, leading to interrupted data throughput when one module performs radio measurements while the other module is engaged in data services.
Innovation Solution
A processor in the wireless communication device reduces scheduled monitoring tasks associated with a secondary subscriber identity card to allow the primary card to perform packet-switched data services while maintaining mobility and receiving network messages, thereby enhancing data rate and reducing performance degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single transceiver is shared between multiple wireless communication modules, then device complexity is reduced, but data rate and throughput are degraded due to lack of coordination
Solution Approach 1:
A transceiver coordinator is introduced as an intermediary component that manages and coordinates access to the shared transceiver between multiple wireless communication modules. The coordinator receives service requests from different modules, determines priority and availability, and grants transceiver access rights accordingly, preventing unauthorized interruptions and ensuring efficient resource allocation.
Solution Approach 2:
The system implements dynamic transceiver allocation where the transceiver can be selectively assigned to different wireless communication modules based on real-time service requirements, priority levels, and availability status. The coordination mechanism allows flexible switching and resource sharing rather than static assignment, optimizing data rate and throughput for active services.
2Reliability
If one wireless communication module performs scheduled monitoring tasks to maintain mobility, then mobility is maintained, but data throughput is interrupted when another module performs packet-switched data services
Solution Approach 1:
The transceiver coordinator ensures continuous data service by preventing scheduled monitoring tasks from interrupting active packet-switched data services. When a module is engaged in data transmission, the coordinator blocks monitoring requests from other modules, ensuring uninterrupted data throughput while still maintaining mobility functionality through coordinated scheduling.
Solution Approach 2:
The system checks the availability and operational status of the transceiver before granting access to perform scheduled monitoring tasks. By preliminarily verifying whether the transceiver is free or currently engaged in data services, the coordinator prevents conflicts and interruptions, ensuring that monitoring only occurs when it will not degrade data throughput.
3Ease of operation
If multiple wireless communication modules operate independently without coordination, then ease of operation is improved, but performance degradation occurs due to transceiver conflicts
Solution Approach 1:
The transceiver coordinator acts as a mediation layer that maintains the independence of wireless communication modules while ensuring reliable operation. Each module can independently request transceiver access and receive services without direct interaction with other modules, while the coordinator manages conflicts and coordinates resource allocation in the background, preserving both ease of operation and service performance.
