Question: What information elements are typically contained within the EF5GSN3GPPLOCI file on a USIM, when service n°122 is "available" in EFUST, for non-3GPP access in a 5G network?
Option 1: IMSI (International Mobile Subscriber Identity), IMEI (International Mobile Equipment Identity), and 4G update status
Option 2: 5G-GUTI (5G Globally Unique Temporary Identifier), Last visited registered TAI (Tracking Area Identity) in 4G, and EPS update status
Option 3: MSISDN (Mobile Station International Subscriber Directory Number), Last visited cell ID in 3G, and UMTS update status
Option 4: 5G-GUTI (5G Globally Unique Temporary Identifier), Last visited registered TAI (Tracking Area Identity) in 5GS, and 5GS update status
Explanation: This question requires understanding of the specific elements related to non-3GPP location information in a 5G context, as stored on a USIM. The correct answer, Option 4, accurately reflects the information specified for EF5GSN3GPPLOCI when service n°122 is "available", including the 5G-GUTI for temporary identification, the last visited TAI in 5GS for location tracking, and the 5GS update status to indicate the freshness of the stored information. The other options are incorrect because they either reference outdated or unrelated network technologies (3G, 4G, UMTS), incorrect identifiers (IMSI, IMEI, MSISDN), or a mix of these inaccuracies.
