摘要:
Systems and methodologies are described herein that facilitate synchronization of Node B-ordered parameters, such as discontinuous transmission (DTX)/discontinuous reception (DRX) status, following a handover failure and/or other suitable triggering events. As described herein, upon failure of a handover from a source Node B to a target Node B, a mobile device can return to the source Node B and synchronize with the source Node B with respect to DTX/DRX status and/or other Node B-ordered parameters. DTX/DRX synchronization can be performed by setting DTX/DRX status to a default state, a last DTX/DRX state utilized prior to initiation of the failed handover, or the like. Identification of the last DTX/DRX state can be conducted as described herein according to an analysis of respective orders communicated by the source Node B in relation to respective time intervals following initiation of the failed handover.
