Dynamic Mode Selection for Mobile Station Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-mode mobile stations consume excessive power and may experience unexpected failures due to excluding unused or unselected modes during network searches in mobile communication systems.
Innovation Solution
A mode selection method that dynamically calculates and adjusts the preferred modes based on the current environmental state, allowing the mobile station to change its settings to match the available network modes, including searching unselected modes during recovery procedures to optimize power usage and ensure connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile station searches all RF channels within all supported modes, then network coverage and reliability are improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the mode selection configurable and adaptable rather than fixed. The mobile station can dynamically adjust which modes to search based on user preferences, operator settings, and environmental conditions, resolving the contradiction between comprehensive mode searching for reliability and selective mode searching for power savings
Solution Approach 2:
The patent changes the parameter of mode selection by introducing a configurable mode selection mechanism that allows switching between different mode combinations. This enables the system to adapt the searching behavior (which modes to include/exclude) based on current needs, thereby balancing reliability and power consumption
2Use of energy by moving object
If the mobile station excludes unused modes from modes of operation, then power consumption is reduced, but unexpected failures may occur if useful modes are excluded
Solution Approach 1:
The configurable mode selection allows the mobile station to dynamically adjust its mode set based on actual network conditions and user needs. This dynamic adaptation prevents permanent exclusion of potentially useful modes while enabling power savings when certain modes are confidently determined to be unused in the current environment
Solution Approach 2:
The system incorporates feedback mechanisms where the mobile station can detect network availability in different modes and adjust its mode selection accordingly. This feedback loop ensures that modes are not permanently excluded even if they appear unused, preventing unexpected failures while still allowing power optimization
3Device complexity
If the mobile station uses a fixed mode selection setting, then device complexity is reduced, but adaptability to different environmental states deteriorates
Solution Approach 1:
The patent introduces dynamics by allowing mode selection to change based on environmental state rather than being fixed. The mobile station can adapt its mode configuration according to user preferences, operator policies, and detected network conditions, achieving environmental adaptability without requiring complex real-time analysis
Solution Approach 2:
The system performs preliminary actions by pre-configuring mode selections based on user preferences and operator settings before actual network searching begins. This preliminary configuration reduces the need for complex real-time decision-making while still providing adaptability to different environmental states
