Adaptive mobility measurement for continuous packet connectivity

摘要

The present disclosure provides a method for making mobility measurements in a cellular telephone network that includes assessing the quality of the downlink signal from an active cell during multiple discontinuous operation time periods. If the quality metric exceeds a threshold, the method calls for performing a mobility measurement on the downlink signal during a first time interval. If the quality metric is less than the threshold, the method calls for performing the mobility measurement on both the downlink signal from the identified cells and a downlink signal from a previously un-identified cell during a second time interval that is greater than the first time interval.

1. A method for operating a user equipment in a cellular network, comprising:
at the user equipment, while maintaining a connectivity with the cellular network in a discontinuous mode of operation, discontinuously receiving downlink signals from an active cell of the cellular network; periodically assessing a quality metric for reception of the downlink signals to the user equipment from the active cell; selectively performing mobility measurements on one of the downlink signals only from the active cell during a first discontinuous operation time period when the quality metric exceeds a threshold; selectively performing mobility measurements on both one of the downlink signals from the active cell and at least another downlink signal from another cell previously un-identified during a second discontinuous operation time period that is greater than the first discontinuous operation time period but less than a discontinuous reception (DRX) operation cycle when the quality metric is less than the threshold.
