摘要： A method and system for releasing an Internet Protocol (IP) version 4 address using a Dynamic Host Configuration Protocol (DHCP) release in a Proxy Mobile IP version 6 (PMIPv6) of a third Generation Partnership Project (3GPP) Evolved Packet Core (EPC). The method includes transmitting a DHCP release request from a Serving GateWay (SGW) to a Packet Data Network (PDN) GW, transmitting a binding revocation from the PDN GW to the SGW, acknowledging the binding revocation from the SGW to the PDN GW, and deleting the IP version 4 connection for an active PDN connection.

摘要： 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.

摘要： A method for releasing an internet protocol (IP) address by a packet data network gateway (PGW) in a mobile communication system comprises allocating, by the PGW, an internet protocol version 4 (IPv4) address and an internet protocol version 6 (IPv6) address to a user equipment (UE) to activate a packet data network (PDN) connection between the UE and the PGW. Receiving, by the PGW, a dynamic host configuration protocol (DHCP) release message from a serving gateway (SGW). Transmitting, by the PGW, to the SGW, a binding revocation message including information indicating release of the IPv4 address with the PDN connection between the UE and the PGW remaining active. Receiving, by the PGW, a binding revocation acknowledge message to acknowledge release of the IPv4 address from the SGW.
