PURPOSE: A handover method in an advanced mobile communication system is provided to minimize the loss of packets generated in the process of an handover, to reduce handover processing delay, and to decrease network loads due to frequent registration procedures dependent on the location movement of mobile terminals. CONSTITUTION: An MN(Mobile Node) in an active state ignores a registration procedure, without executing it, even though an agent advertising message is received from a drift AS(Access Station). Instead, the MN transmits a measurement report message through an RRC connection with a serving AS. The serving AS reads channel status from the received message. If the serving AS determines the start of a handover procedure, the serving AS transmits a connection setup request message, containing physical layer configuration information and MAC configuration information for radio link setup, to the drift AS. Receiving the connection setup request message, the drift AS allocates a radio resource according to the received configuration information and executes MAC entity setup and radio link setup to support the transmission of data.
