Abstract
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.
