Summary

In Recommendation ITU-T Q.3202.1, a couple of authentication protocols for heterogeneous access authentication are discussed. 3GPP has standardized the 3GPP system-based EAP-AKA for interworking 3GPP and WLAN networks. The WiMax or WLAN device requires an external UICC reader for applying the current EAP-AKA defined in 3GPP TS 33.234. This Recommendation proposes to apply the EAP-AKA protocol to non-3GPP network devices not equipped with UICC for interworking among 3GPP, WiMax, and WLAN in NGN.
