Abstract:
A method for handover of a wireless subscriber communication unit from a first base station to a second base station in a wireless network is described. The method comprises at the wireless subscriber communication unit receiving a handover command message from the first base station. At the first base station, the method comprises sending a scheduling request message to the second base station, in response to an acknowledgement message sent from the wireless subscriber communication unit. The method further comprises, at the second base station, scheduling, in response to the scheduling request message, at least one uplink scheduling resource (UL-SCH) for the wireless subscriber communication unit to transmit a handover (HO) confirmation message to the second base station; and receiving a handover confirmation message from the wireless subscriber communication unit on the at least one uplink scheduling resource (UL-SCH).
