ABSTRACT:
Disclosed is a handover controlling method in an RNC connected to a first Node B and a second Node B in a mobile communication system where a USTS service occurs between the first Node B and a UE within a cell of the first Node B and the UE hands over when the UE is located in a handover area across the cell areas of the first Node B and the second Node B adjacent to the first Node B. The method comprises determining whether the handover for the UE is possible or not; transmitting handover information to the second Node B if the handover is possible; and transmitting a command to the UE through the first Node B, requesting the UE to hand over to the second Node B if the UE receives a response message indicating that the handover is possible from the second Node B.
