Abstract: A method and apparatus for controlling inter-PLMN handover based on CSG lists of equivalent PLMNs is provided. A method for receiving subscriber information of a terminal at a Mobility Management Entity (MME) includes transmitting an update location request message for the terminal to a Home Subscriber Server (HSS), and receiving an update location acknowledgement message with the subscriber information of the terminal from the HSS, wherein the update location request message comprises a list of equivalent Public Land Mobile Networks (PLMNs) among which the MME supports inter-PLMN handover of the terminal. The method and apparatus for controlling inter-plan handover to a CSG cell according to the present invention is characterized in that a control apparatus of a core network acquires the allowed CSG lists for determining a User Equipments (UEs) capability of access to a CSG cell and determines whether to permit inter-PLMN handover based on the allowed CSG lists.

Abstract: Methods and apparatus are provided for releasing an Internet Protocol (IP) address by a Packet Data Network (PDN) GateWay (PGW) in a mobile communication system. The PGW allocates, to a User Equipment (UE), an Internet Protocol version 4 (IPv4) address and an Internet Protocol version 6 (IPv6) address to activate a PDN connection. If the UE releases the IPv4 address: the PGW identifies whether a PDN type associated with the PDN connection is an IPv4/v6, which indicates that the UE is allocated both the IPv4 address and the IPv6 address; the PGW transmits, to a Serving GateWay (SGW), a Binding Revocation message including information indicating release of the IPv4 address with the PDN connection remaining if the PDN type is the IPv4/v6; and the PGW receives, from the SGW, a Binding Revocation acknowledge message to acknowledge release of the IPv4 address.

Abstract translation: 提供了用于在移动通信系统中通过分组数据网络（PDN）GateWay（PGW）释放因特网协议（IP）地址的方法和装置。 PGW向用户设备（UE）分配因特网协议版本4（IPv4）地址和因特网协议版本6（IPv6）地址以激活PDN连接。 如果UE释放IPv4地址：PGW识别与PDN连接相关联的PDN类型是否是IPv4 / v6，其指示UE被分配IPv4地址和IPv6地址; 如果PDN类型是IPv4 / v6，则PGW向服务网关（SGW）发送包括指示IPv4地址的释放的信息的绑定撤销消息，其中PDN连接剩余; 并且PGW从SGW接收绑定撤销确认消息以确认IPv4地址的发布。
