SOFT HANDOVER TIMING UPDATES

摘要

In a mobile communications network, drifts in timing of user equipment in soft handover may be accounted for by measuring the offset between the current timing of the user equipment and the first significant path of downlink frames from cells of the active set at first and second instances. Differences in the respective offsets from the first and second instances may be calculated to determine if the drift is unidirectional in time for all cells of the active set. A unidirectional drift in the offsets is indicative of a drift in timing of the user equipment, allowing the current timing to be momentarily unfrozen and updated.
