Abstract
A Packet Data Network Gateway (PGW) network node of an Evolved Packet Core (EPC) for interfacing with an IP Multimedia Core Network Subsystem (IMS) comprises an IP address assignment functionality module configured to assign both IPv4 and IPv6 addresses to a User Equipment (UE) requesting an IPv6 address, a Network Address Translation-Application Layer Gateway (NAT64-ALG) functionality module and PGW configured to translate between IPv4 and IPv6 addresses, a Gx interface toward a Policy Control and Charging Rules Function (PCRF) network node configured to transmit the UE's IPv4 address to the PCRF, and an SGi interface toward an application node of the IMS configured the UE's IPv4 address to the application node, and to transmit and receive IP media packets between the IMS and the UE after IPv4 and IPv6 address translation.
