Question: What state will a UE operating in single-registration mode enter upon successful completion of an attach or tracking area updating procedure in S1 mode for 3GPP access and EMM?
Option 1: 5GMM-DEREGISTERED and EMM-REGISTERED.NO-CELL-AVAILABLE
Option 2: 5GMM-REGISTERED.NO-CELL-AVAILABLE and EMM-REGISTERED.NORMAL-SERVICE
Option 3: 5GMM-REGISTERED.NORMAL-SERVICE and EMM-REGISTERED.NO-CELL-AVAILABLE
Option 4: 5GMM-DEREGISTERED and EMM-REGISTERED.NORMAL-SERVICE
Explanation: In S1 mode, upon successful completion of an attach or tracking area updating procedure, the UE operating in single-registration mode shall enter substates 5GMM-REGISTERED.NO-CELL-AVAILABLE for 3GPP access and EMM-REGISTERED.NORMAL-SERVICE. This is because the UE has successfully attached to the network and is now registered for normal services.
