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.
