Question: What happens to the roaming and access restriction information for a UE when it is not available at the gNB?
Option 1: The gNB will apply default restrictions for subsequent mobility actions.
Option 2: The gNB will ignore any restrictions and allow the UE to roam freely.
Option 3: The gNB shall consider that there is no restriction for subsequent mobility actions except for PNI-NPN mobility.
Option 4: The gNB will request the AMF to provide the roaming and access restriction information.
Explanation: According to the text, if the roaming and access restriction information is not available for a UE at the gNB, the gNB shall consider that there is no restriction for subsequent mobility actions except for PNI-NPN mobility. This means that the gNB will not apply any restrictions, but will still follow the rules for PNI-NPN mobility as described in TS 23.501.
