CALL RECOVERY IN TD-SCDMA HANDOVER FAILURE

摘要

A method of wireless communication includes measuring and recording a path loss of a first downlink signal from a source base station, prior to attempting handoff from the source base station to a target base station. The path loss of a second downlink signal from the source base station is measured after unsuccessful handoff from the source base station to the target base station. A UE communicates with the source base station, after unsuccessful handoff, using an uplink timing corresponding to an uplink timing recorded prior to attempting handoff when a difference between the path loss of the first downlink signal and the path loss of the second downlink signal fails to meet a threshold value. A new uplink timing is used when the difference meets the threshold value.
