EAP Attributes for WiFi - EPC Integration
draft-ietf-netext-wifi-epc-eap-attributes-02
Abstract
With WiFi beginning to establishing itself as a trusted access
network for service providers, it has become important to provide
functions commonly available in 3G and 4G networks in WiFi access
networks. Such functions include Access Point Name (APN) Selection,
multiple Packet Data Network (PDN) connections and seamless mobility
between WiFi and 3G/4G networks.
EAP/AKA (and EAP/AKA') is standardized by 3GPP as the access
authentication protocol for trusted access networks. This IETF
specification is required for mobile devices to access the 3GPP
Evolved Packet Core (EPC) networks. This document defines a few new
EAP attributes and procedures to provide the above-mentioned
functions in trusted WiFi access networks.
