Abstract: A method for a load balancing using statistical information in a base station of a wireless communication system is provided. The method includes measuring a load of at least one cell managed by the base station; exchanging load information of the measured cell with at least one neighboring base station; determining at least one Mobility Load Balancing (MLB) application candidate cell in which a Cell Individual Offset (CIO) change is necessary using the load information; determining at least one MLB application target cell in the at least one MLB application candidate cell; performing a CIO change procedure with the at least one MLB application target cell; selecting at least one User Equipment (UE) to notify a CIO change; and notifying the selected at least one UE of the CIO change.

Abstract: A method for obtaining an identifier of a new cell in a radio communication system is provided. The method includes receiving information associated with the new cell from a user equipment (UE), obtaining an evolved universal terrestrial radio access (EUTRA) cell global identifier (ECGI) of the new cell, if it is determined based on the information associated with the new cell that the new cell is not set as a neighbor cell, determining whether a public land mobile network (PLMN) identifier (ID) (PLMN ID) in the ECGI is included in a relation table including at least one of PLMN IDs and shared PLMN IDs, and receiving an identifier of the new cell from a server, if the PLMN ID in the ECGI is included in the relation table.

Abstract: A method for acquiring a cell identifier by a source cell in a radio communication system is provided. The method includes receiving information about a new cell from a User Equipment (UE) in the source cell, acquiring an Evolved Universal Terrestrial Radio Access (EUTRA) Cell Global Identifier (ECGI) of the new cell from the UE, if it is determined based on the information about the new cell that there is no neighbor relationship with the new cell, determining whether a Public Land Mobile Network (PLMN) Identifier (ID) (PLMN ID) in the ECGI is included in a mapping table between a primary PLMN ID and a shared PLMN ID, and acquiring an X2 Internet Protocol (IP) address of the new cell from an Evolved Packet Core (EPC) according to the determination results.
