Indeed, it allows bridging with other link layer technologies, termed “Non-3GPP access networks”. Wi-Fi for instance is seen as such a non-3GPP access technology, on which the 3GPP Authentication, authorization and accounting (AAA) infrastructure can be used. As Jens also noted, this is unlikely to happen outside of the commercial / telco / ISP space. People have been trying to do business-to-business roaming for 25 years. It hasn't taken off. Even WiFi roaming integration has taken decades to get going. There's now OpenRoaming, which is nice. But I was trying to get something similar done 15+ years ago, and gave up due to lack of interest and/or perceived value. > [AFT] If you consider the identifier for the sole purpose of identification, I don’t see any problem with using this ID to do AAA on any type of access layer technology. For instance, with Wi-Fi, the identity credentials present in the SIM can be used in a RADIUS or DIAMETER authentication and network attachment procedure (This is actually done in several network offloading use cases). Telcos are moving to anonymous identifiers for privacy issues, especially in the WiFi offload case. The only people who need to see the actual identifiers are (a) the end user, and (b) the ISP that the user has a contractual relationship with. This process is defined in RFC 7542 (NAI). Perhaps this is off-topic for here, but I think it would be very nice to permit roaming for non-corporate entities. If I visit my friends house, why do I need to go through complex steps to configure WiFi? He (or his systems) know what the configuration is. He trusts his systems. I know him. He trusts me (at least for WiFi access). Why is there nothing to "close the loop" ? Implementing that would require some kind of global addressing scheme. Alan DeKok.
