Abstract
A method and apparatus for increasing the success rate of a handover of a connected mode UE while minimizing the power consumption of the UE during DRX operation in a mobile communication system is provided. The method includes the steps of transmitting a cell change report to the serving base station and then suspending the DRX operation to transition to an active mode; receiving a handover command message and completing the handover to a target cell; checking if the handover command message includes a DRX resume command; waiting until a control message including the DRX resume command is received from the target base station; and after the control message including the DRX resume command is received transitioning from the active mode to a sleep mode and resuming the DRX operation.

Claim
1. A method of performing a handover of UE in connected mode from a serving base station to a target base station during DRX operation in a mobile communication system, the method comprising the steps of: transmitting a cell change report to the serving base station in which the UE is located, and then suspending the DRX operation to transition to an active mode; receiving a handover command message transmitted from the serving base station, and completing the handover to a target cell under a control of the target base station; checking if the handover command message includes a DRX resume command; when the DRX resume command is not included in the handover command message, waiting until a control message including the DRX resume command is received from the target base station; and transitioning from the active mode to a sleep mode, and resuming the DRX operation after the control message including the DRX resume command is received.
2. The method as claimed in claim 1, further comprising signaling a DRX-related parameter, a measurement-related parameter, a measurement type to suspend the DRX operation from a network to the UE during call setup.
3. The method as claimed in claim 2, wherein a predetermined measure type is sued as the measurement type to suspend the DRX operation.
4. The method as claimed in claim 2, further comprising: calculating wakeup times by suing the DRX-related parameter received during the call setup, and then transitioning to the sleep mode; transmitting the measurement report message, and checking if the measurement report message corresponds to the measurement type to suspend the DRX operation when the UE wakes up at each wakeup time to perform a measurement operation, and as a result of the measurement operation, a measurement report message is generated; and suspending the DRX operation, and continuing to turn on a transceiver of the UE when the measurement report message corresponds to the measurement type to suspend the DRX operation.
5. The method as claimed in claim 4, wherein the cell change report indicates that the measurement report message corresponds to the measurement type to suspend the DRX operation.
6. An apparatus for performing a handover of a connected mode UE from a serving base station to a target base station during DRX operation in a mobile communication system, the apparatus comprising: a transceiver for receiving a DRX parameter, a cell change parameter, and measurement type information based on which the DRX operation is suspended; a DRX controller for controlling the transceiver to be turned on/off by using the received DRX parameter; and a radio resource control (RRC) entity for measuring reception qualities for neighboring cells through the cell change parameter, applying a control signal corresponding to a result of the measuring to the DRX controller to turn on the transceiver and report a cell change to the serving base station, and then controlling the UE to perform the handover to the target base station.
7. The apparatus as claimed in claim 6, wherein the RRC entity checks a handover command message transmitted from the serving base station, controls the DRX controller to maintain the transceiver in an on- state until a control message including a DRX resume command is received from the target base station, and controls the DRX controller to turn off the transceiver after the control message including the DRX resume command is received.']
