The Third Generation Partnership Project (3GPP) S2b reference point [TS23402], specified by the 3GPP system architecture, defines a mechanism for allowing a mobile node (MN) attached in an untrusted, non-3GPP IP access network to securely connect to a 3GPP network and access IP services. In this scenario, the mobile node establishes an IPsec Encapsulating Security Payload (ESP) tunnel [RFC4303] to the security gateway called the Evolved Packet Data Gateway (ePDG) that in turn establishes a Proxy Mobile IPv6 (PMIPv6) [RFC5213] or GPRS Tunneling Protocol (GTP) [TS23402] tunnel to the Packet Data Network Gateway (PGW) [TS23402] where the mobile node's session is anchored.

3GPP IP Multimedia Subsystems (IMS) Option for the Internet Key Exchange Protocol Version 2 (IKEv2)
This document defines two new configuration attributes for the Internet Key Exchange Protocol version 2 (IKEv2). These attributes can be used for carrying the IPv4 address and IPv6 address of the Proxy-Call Session Control Function (P-CSCF). When an IPsec gateway delivers these attributes to an IPsec client, the IPsec client can obtain the IPv4 and/or IPv6 address of the P-CSCF server located in the 3GPP network.
