Power-Aware System Selection for Multi-Mode Wireless Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-mode wireless receivers consume excessive power when connected to multiple wireless technology systems, as they must monitor and process signals from various systems simultaneously, leading to rapid battery drain, especially in dynamically changing RF environments.
Innovation Solution
A power-aware system selection technique that determines combinations of wireless technology systems to minimize combined power penalties, such as duty cycles or power consumption, during idle mode operations, using a system determination module, power penalty monitor, and selection module within a wireless communications protocol stack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a receiver is connected to multiple wireless technology systems simultaneously, then the receiver can handle multiple services (voice and data), but the power consumption increases significantly
Solution Approach 1:
The patent implements dynamic system selection that adapts to changing RF environments and service requirements. The receiver dynamically chooses which wireless technology systems to connect to based on real-time conditions, transitioning between different system combinations to optimize power consumption while maintaining service capability.
Solution Approach 2:
The patent changes the parameter of system selection by evaluating multiple factors including QoS parameters, signal quality, band preference, scheduling, and power consumption characteristics. This multi-parameter evaluation enables the receiver to select system combinations that balance service requirements with power efficiency.
2Reliability
If the receiver monitors multiple wireless technology systems for pages, then it can receive both voice and data communications, but the battery drains much more quickly
Solution Approach 1:
The patent applies partial monitoring by selectively monitoring only the necessary wireless technology systems based on current service requirements. Instead of continuously monitoring all available systems, the receiver monitors only those systems that are currently active or likely to have pending communications, reducing overall monitoring burden and power consumption.
Solution Approach 2:
The patent implements feedback mechanisms that continuously evaluate system performance, power consumption, and service requirements. This feedback loop enables the receiver to adjust its monitoring strategy in real-time, reducing monitoring activity on systems that are not currently needed while maintaining reliable page reception on active systems.
3Ease of operation
If default systems are configured for voice and data, then system selection is simplified, but the configuration may not be well suited to dynamically changing RF environments
Solution Approach 1:
The patent transforms static default system configuration into a dynamic selection process. Instead of relying on fixed default settings, the system continuously evaluates current RF conditions, service requirements, and system performance to dynamically select the most appropriate wireless technology systems, enabling adaptation to changing environments while maintaining ease of operation through automated decision-making.
Solution Approach 2:
The patent implements self-service by enabling the receiver to automatically select and configure its own wireless technology systems without requiring manual user intervention. The system autonomously evaluates available systems, determines the optimal combination based on predefined criteria, and configures connections automatically, combining simplicity with environmental adaptability.

AI summary
A method for power management for use in system selection by simultaneous receivers taking into account power use during an idle state. A power penalty is determined for each of a plurality of wireless technology systems available to a receiver when conducting page monitoring sequences. Combined power penalties are determined for various combinations of wireless technology systems. Wireless technology systems are selected in a preferred combination having a least combined power penalty for monitoring pages during an idle mode.
