Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio resource measurements in wireless communication devices consume significant power, limiting battery life and contributing to power outages, especially in devices with multiple radio connections.
Innovation Solution
Perform first and second radio channel measurements on different wireless networks, determine a relationship between them, and control the measurement activity of the second channel based on this relationship to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio resource measurements are performed frequently on multiple radio channels to maintain connection quality, then connection reliability is improved, but power consumption increases
Solution Approach 1:
The patent creates a virtual copy of the second radio channel measurements by estimating them from the first radio channel measurements using a determined relationship. This estimated copy replaces actual measurements on the second channel, reducing measurement activity and power consumption while maintaining sufficient information for connection management
Solution Approach 2:
Instead of performing full measurements on all radio channels continuously, the patent performs measurements partially - only on the first radio channel while deriving second channel measurements through estimation. This partial action approach maintains connection reliability while significantly reducing power consumption
2Measurement precision
If radio resource measurements are performed on each radio connection to adapt to channel changes, then transmission quality is improved, but battery life decreases
Solution Approach 1:
The patent generates estimated measurement values for the second radio channel by applying a determined relationship to first channel measurements. This copying approach provides sufficient measurement precision for transmission quality adaptation without the full power cost of direct measurements on all channels
Solution Approach 2:
The patent performs preliminary determination of the relationship between first and second radio channels during periods when measurements are feasible. This preliminary action enables later estimation without full measurements, extending battery life while maintaining measurement precision when needed
3Stability of the object's composition
If measurement activity on multiple radio channels is increased to detect signal changes, then connection stability is improved, but power consumption increases
Solution Approach 1:
The patent creates estimated measurement values that copy the essential information from actual second channel measurements. This allows the system to detect signal changes and maintain connection stability without the excessive power consumption of continuous direct measurements on all channels
Solution Approach 2:
The patent uses feedback from actual measurements to update the determined relationship between first and second radio channels. This feedback mechanism ensures that the estimation remains accurate and connection stability is maintained while power consumption is reduced through selective measurement

AI summary
There is provided controlling radio channel measurements on radio channels of different wireless networks. A wireless communication device performs first radio channel measurements on a first radio channel of a first wireless communication network and second radio channel measurements on at least one second radio channel of a second wireless communication network. It is determined, on the basis of the first radio channel measurements and the second radio channel measurements, a relationship between the first radio channel and the at least one second radio channel. Measurement activity of the at least one second radio channel is controlled on the basis of at least the determined relationship and the first radio channel measurements.
