Claim:
A method for inter handover with consideration of load status of cells by a mobile station in a wireless communication system, the method comprising: receiving a down link channel descriptor (DCD) message and a neighbor advertisement (MOB-NBR-ADV) message from a serving base station, the DCD message comprising a first load status field that indicates whether a load status of a cell of the serving base station is heavy, the MOB-NBR-ADV message comprising a second load status field that indicates whether a load status of an intra neighbor cell is heavy; scanning neighbor cells in an inter network if channel quality of the serving base station is less than a scanning threshold, the first load status field indicates the load status of the cell of the serving base station is heavy, and the second load status field indicates the load status of the intra neighbor cell is heavy; and performing inter handover based on load status of the neighbor cells in the inter network and a result of the scanning.
