Solution Overview
Problem
Wireless communication devices experience frequent channel switching due to varying signal quality and interference, leading to increased power consumption as base stations adjust transmission power to maintain service quality.
Innovation Solution
A method to reduce channel switching by determining a mobile device's stationary or semi-stationary state, creating a transmission power variation table, identifying the most frequently used transmission power, and increasing the lowest allowable transmission power to minimize handover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station adjusts transmission power or switches communication channels to maintain service quality, then communication quality is improved, but power consumption increases and handover operations become frequent
Solution Approach 1:
The system performs preliminary analysis of transmission power variations by collecting and storing power adjustment records before handover decisions are made. This advance preparation allows the mobile device to predict future power needs and optimize handover timing, reducing frequent power adjustments and handovers that would otherwise increase power consumption while maintaining communication quality
Solution Approach 2:
The invention changes the parameter of transmission power by analyzing historical power adjustment data and identifying optimal power levels. By determining the most frequently used transmission power from stored records and using it as a reference for future adjustments, the system reduces unnecessary power changes and handover operations, thereby lowering power consumption while preserving service quality
2Reliability
If the base station switches communication channels to maintain service quality, then communication quality is improved, but the number of handover operations increases
Solution Approach 1:
The system collects and stores transmission power adjustment records in advance before handover decisions are required. This preliminary data gathering allows the mobile device to analyze power variation patterns and make informed handover decisions, reducing the frequency of handover operations while maintaining service quality through data-driven channel switching
Solution Approach 2:
The invention implements a feedback mechanism where transmission power adjustment records are continuously collected, analyzed, and used to inform future handover decisions. By determining the most frequently used transmission power from historical data and applying this knowledge to subsequent channel switching decisions, the system reduces unnecessary handovers while preserving service quality
