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: Methods and apparatuses are provided for allocating an internet protocol (IP) address by a packet data network gateway (PGW) in a wireless communication system. A binding update message to request the IP address of a terminal, is received from a serving gateway (SGW). The IP address of the terminal is allocated. A binding acknowledgement message including the IP address is transmitted to the SGW. A dynamic host configuration protocol (DHCP) discover message is received from the SGW. A DHCP offer message including the IP address assigned to the terminal, is transmitted to the SGW.

Abstract: Methods and apparatuses are provided for releasing an internet protocol (IP) address by a packet data network gateway (PGW) in a mobile communication system. The PGW allocates an IP version 4 (IPv4) address and an IP version 6 (IPv6) address to a terminal to establish a packet data network (PDN) connection between the terminal and the PGW. The PGW identifies a PDN type associated with the PDN connection if an event of releasing the IPv4 address has occurred. 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 IPv4 and IPv6. The PGW receives a binding revocation acknowledge message in response to the binding revocation request message, from the SGW.
