Motion Based Search and Measurement Periodicity

摘要

Adjusting search and measurement periodicity based on device motion. A wireless device may camp on a serving cell. Signal strength, signal quality, and signal to noise ratio of the serving cell may be measured. If each is above a respective threshold, and if the wireless device is stationary, the periodicities at which searches and neighbor cell measurements are performed may be adjusted (e.g., increased) from baseline periodicities.

1. A method for a wireless user equipment (UE) device, the method comprising:
camping on a first cell in idle mode; measuring a signal strength metric, a signal quality metric, and a signal to noise ratio (SNR) of the first cell; determining that signal strength of the first cell is above a signal strength threshold, signal quality of the first cell is above a signal quality threshold, and SNR of the first cell is above a SNR threshold; determining that the UE has been stationary for at least a first amount of time; increasing neighbor cell search periodicities in accordance with a first predefined factor based on determining that signal strength of the first cell is above the signal strength threshold, signal quality of the first cell is above the signal quality threshold, SNR of the first cell is above the SNR threshold, and the UE has been stationary for at least the first amount of time; and increasing neighbor cell measurement periodicities in accordance with a second predefined factor based on determining that signal strength of the first cell is above the signal strength threshold, signal quality of the first cell is above the signal quality threshold, SNR of the first cell is above the SNR threshold, and the UE has been stationary for at least the first amount of time.
