Method for data transfer with a mobile station while in discontinuous reception state
First Claim
1. A method for data transfer initiation for a wireless device capable of operating in discontinuous reception mode comprising:
- monitoring a channel condition of a handover candidate cell while in a sleep cycle of the discontinuous reception mode;
sending a measurement report to the serving cell;
receiving a pending data indicator; and
remaining awake to receive data associated with the pending data indicator.

Abstract
A method for sleep mode during an impending handover is disclosed. The method comprises receiving (104) from a network a handover threshold value. Then once in sleep mode, monitoring (128) a channel condition of a handover candidate cell and determining that the handover threshold value of the handover candidate cell has been exceeded. After receiving a pending data indicator, remaining awake (134) to receive a data set associated with the pending data indicator. The network re-schedules (218) transmission of the data set to the mobile station.

10. A method in a wireless communication device comprising:
-
sending a channel condition measurements report of a plurality of handover candidates to the current serving cell; and
remaining awake if the channel condition measurement of a handover candidate is greater than a handover threshold value and there is an indication of pending data from the network. - View Dependent Claims (11)

12. A method in a current serving cell portion of a communication network that is serving a mobile station comprising:
-
receiving data that is to be sent to the mobile station and storing the data in a buffer;
receiving a message from the mobile station that includes a measurement report for a neighboring cell; and
re-scheduling the data transmission at an earlier time than originally scheduled. - View Dependent Claims (13, 14, 15)

16. A method in a wireless communication device comprising:
-
periodically checking channel conditions of a plurality of handover candidates while the wireless communication device is in discontinuous reception mode;
receiving a pending downlink transmission status in response to a measurement of the channel condition of any of the handover candidates being greater than a first candidate threshold; and
remaining in an active state to receiving data from the current serving cell.
