Abstract
A method for a handover with consideration of load status of cells is disclosed. The method for intra handover with consideration of load status of cells by a mobile station in a wireless communication system includes receiving a neighbor advertisement (MOB-NBR-ADV) message including load status information of neighbor cells from a serving base station, and performing intra handover according to the load status information of neighbor cells if there is at least a neighbor cell of which channel quality is equal to or higher than a handover threshold for a time duration among neighbor cells in an intra network.

A method for intra handover with consideration of load status of cells by a mobile station in a wireless communication system comprising:
- receiving a neighbor advertisement (MOB-NBR-ADV) message including load status information of neighbor cells from a serving base station;
- and
- performing intra handover according to the load status information of neighbor cells if there is at least a neighbor cell of which channel quality is equal to or higher than a handover threshold for a time duration among neighbor cells in an intra network.
A method for intra handover with consideration of load status of cells by a mobile station in a wireless communication system comprising:
- receiving load status information of a cell of a serving base station through a down link channel descriptor (DCD) message from the serving base station;
- performing network entry to the serving base station if load status of the serving base station is not heavy;
- receiving load status information of neighbor cells through a neighbor advertisement (MOB-NBR-ADV) message from a serving base station;
- and
- performing intra handover according to the load status information of neighbor cells if there is at least a neighbor cell of which channel quality is equal to or higher than a handover threshold for a time duration among neighbor cells in an intra network.
A method for inter handover with consideration of load status of cells by a mobile station in a wireless communication system comprising:
- receiving load status information of a cell of a serving base station through a down link channel descriptor (DCD) message, and receiving load status information of neighbor cells through a neighbor advertisement (MOB-NBR-ADV) message from the serving base station;
- scanning neighbor cells in an inter network if the serving base station's channel quality is less than a scanning threshold and load status of all intra cells is heavy;
- and
- performing inter handover according to load status of the neighbor cells in an inter network and a result of the scanning.
A method for inter handover with consideration of load status of cells by a mobile station in a wireless communication system comprising:
- receiving load status information of a cell of a serving base station through a down link channel descriptor (DCD) message, and receiving load status information of neighbor cells through a neighbor advertisement (MOB-NBR-ADV) message from a serving base station;
- scanning neighbor cells in an inter network if load status of all intra cells is heavy;
- performing pre-registration according to a result of the scanning;
- and
- performing inter handover according to channel quality and load status of neighbor cells which the mobile station performed pre-registration to if the serving base station's channel quality is less than a scanning threshold.
