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.

Abstract translation: 提供了一种在无线电通信系统中由源小区获取小区标识符的方法。 该方法包括从源小区中的用户设备（UE）接收关于新小区的信息，如果基于所述源单元确定，则从所述UE获取所述新小区的演进通用陆地无线电接入（EUTRA）小区全球标识符（ECGI） 关于与新小区没有邻居关系的关于新小区的信息，确定ECGI中的公共陆地移动网络（PLMN）标识符（ID）（PLMN ID）（PLMN ID））是否被包括在主PLMN ID 和共享PLMN ID，并且根据确定结果从演进分组核心（EPC）获取新小区的X2互联网协议（IP）地址。
