Abstract
A method and a Packet data network GateWay (PGW) for releasing an Internet Protocol (IP) address in a mobile network are provided. The method includes allocating 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; and if the UE releases the IPv4 address, transmitting to a Serving GateWay (SGW) a Binding Revocation message including an indication to release only the IPv4 address from the PDN connection to SGW.
