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.
Working Group Summary:
This document has been in a dormant state for a while. There is no
controversy regarding the document. Using EAP attributes to address a
problem that is faced in mobile networks when attaching via WiFi is
one solution. And there is enough consensus in the WG w.r.t the
There are no known implementations of the attributes for EAP defined
by this document. At this time there is'nt any indication from vendors
or 3GPP to use the approach specified by this document.
The document has acknowledged the one person who has helped in
improving the specification. The document does not specify any media
type or MIB and hence no specialists have been consulted for reviews.
