Solution Overview
Problem
Wireless communication devices face challenges in efficiently switching between different communication modes and frequency spectrums as they move across varying geographic locations, leading to suboptimal network information reception and increased power consumption.
Innovation Solution
A method and device that enter a first wireless communication mode, set a timer to monitor a second mode, and tune away to the second mode only when the device moves beyond a threshold distance, allowing for efficient spectrum switching and reduced power usage by monitoring network information selectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication device continuously monitors network information in the second wireless communication mode, then network information reception is ensured, but power consumption increases
Solution Approach 1:
The device uses a timer to periodically check whether the device is still within the threshold distance from the initial location. Only when the timer expires and the location condition is met does the device tune away to monitor the second wireless communication mode. This periodic checking mechanism avoids continuous monitoring while ensuring network information is received when needed, thereby reducing power consumption while maintaining reliability.
2Reliability
If the wireless communication device tunes away frequently to monitor the second wireless communication mode, then network information reception is improved, but communication continuity in the first mode deteriorates
Solution Approach 1:
The device applies different monitoring behaviors based on location conditions. When the device is within the threshold distance of the initial location, it continues communicating in the first wireless communication mode without tuning away. Only when the device moves beyond the threshold distance does it tune away to monitor the second mode. This location-based differentiation ensures communication continuity is maintained in appropriate areas while network information reception is ensured when needed.
Solution Approach 2:
The device dynamically adjusts its communication mode based on real-time location information. The timer mechanism allows the device to flexibly switch between monitoring the first mode continuously and tuning away to monitor the second mode, depending on whether the location threshold is met. This dynamic adjustment optimizes both communication continuity and network information reception.
3Reliability
If the wireless communication device monitors the second wireless communication mode at every timer expiration, then network information reception is ensured, but device complexity increases
Solution Approach 1:
Instead of monitoring the second wireless communication mode at every possible opportunity, the device uses a timer to create selective monitoring points. The device only tunes away to monitor the second mode when the timer expires and the location condition is satisfied. This partial monitoring approach reduces the complexity of spectrum switching while still ensuring network information is received when the device is in the appropriate location.

AI summary
What is disclosed is a method of operating a wireless communication device. The method includes, while at an initial location, entering a first wireless communication mode that requires tuning to a first frequency spectrum. In response to entering the first wireless communication mode, the method includes setting a timer for monitoring a second wireless communication mode. When the timer expires, the method includes determining if a present location of the wireless communication device is beyond a threshold distance from the initial location. If the present location is beyond the threshold distance from the initial location, then the method includes tuning away from the first frequency spectrum to a second frequency spectrum for the second wireless communication mode and monitoring information for the second wireless communication mode, and if the present location is not beyond the threshold distance from the initial location, then resetting the timer for monitoring the second wireless communication mode.
