Section: 17.2.2 Full Authentication NAI
Content: The Full Authentication NAI in both EAP-SIM and EAP-AKA shall take the form of an NAI as specified in clause 2.1 of IETF RFC 4282 [53]. The format of the Full Authentication NAI shall comply with IETF RFC 4187 [50] when EAP-AKA authentication is used and with IETF RFC 4186 [51], when EAP-SIM authentication is used. The realm used shall be a home network realm as defined in clause 17.2.1. The result will therefore be an identity of the form: "0<IMSI>@gan.mnc<MNC>.mcc<MCC>.3gppnetwork.org", for EAP-AKA authentication and "1<IMSI>@gan.mnc<MNC>.mcc<MCC>.3gppnetwork.org", for EAP-SIM authentication EXAMPLE 1: For EAP AKA authentication: If the IMSI is 234150999999999 (MCC = 234, MNC = 15), the Full Authentication NAI takes the form 0234150999999999@gan.mnc015.mcc234.3gppnetwork.org. EXAMPLE 2: For EAP SIM authentication: If the IMSI is 234150999999999 (MCC = 234, MNC = 15), the Full Authentication NAI takes the form 1234150999999999@gan.mnc015.mcc234.3gppnetwork.org.
