With Wi-Fi emerging as a crucial access network for mobile service providers, it has become important to provide functions commonly available in 3G and 4G networks in Wi-Fi access networks as well. Such functions include Access Point Name (APN) Selection, multiple Packet Data Network (PDN) connections, and seamless mobility between Wi-Fi and 3G/4G networks.
The EAP Authentication and Key Agreement (EAP-AKA), and EAP-AKA', protocol is required for mobile devices to access the mobile Evolved Packet Core (EPC) via Wi-Fi networks. This document defines a few new EAP attributes to enable the above-mentioned functions in such networks. The attributes are exchanged between a client (such as a Mobile Node (MN)) and its network counterpart (such as an Authentication, Authorization, and Accounting (AAA) server) in the service provider's infrastructure.
