Multi-mode Wireless Terminal Diversity Receive Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-mode wireless terminals, such as dual card dual standby mobile phones, face a challenge in maintaining call connection rates due to resource competition between data and call services, where reserving resources for call services compromises data service rates.
Innovation Solution
A multi-mode wireless terminal design where an antenna and transceiver module of one wireless communications standard serve as a diversity receive path for another standard, utilizing a control unit to manage idle timeslots and filter modules to optimize signal reception across different frequency bands, allowing the terminal to utilize idle timeslots for improved receive performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If path resources are reserved for call service to ensure call connection rate, then call service reliability is improved, but data service rate deteriorates
Solution Approach 1:
The patent makes the second wireless communications path serve dual functions: its primary function is for second standard communication, and its secondary function is to act as a diversity receive path for the first standard during idle timeslots. This multi-functionality allows the system to improve first standard call connection rate without permanently dedicating resources away from data services.
Solution Approach 2:
The patent utilizes idle timeslots of the second wireless communications standard periodically to enable the second path to function as a diversity receive path for the first standard. This periodic activation during non-critical periods allows call service monitoring without continuous resource occupation, thereby maintaining data service rates.
2Reliability
If each wireless communications standard uses an individual antenna, then standard-specific performance is optimized, but resource utilization deteriorates
Solution Approach 1:
The patent enables the second antenna module and second transceiver module to serve both the second wireless communications standard and the first wireless communications standard. This universal design allows single resources to support multiple standards, improving overall resource utilization while maintaining standard-specific performance through controlled activation.
Solution Approach 2:
The patent dynamically configures the wireless communications paths based on operational needs. The second path remains primarily dedicated to the second standard but can be dynamically activated as a diversity receive path for the first standard during idle timeslots, providing adaptability without compromising standard-specific optimization.
3Reliability
If path resources are allocated for call service monitoring, then call service reliability is improved, but overall system complexity increases
Solution Approach 1:
The patent reduces system complexity by making existing paths multi-functional rather than adding dedicated monitoring paths. The second path serves both as a primary path for the second standard and as a diversity receive path for the first standard, eliminating the need for additional dedicated monitoring infrastructure.
