Question: What is the outcome when no E-UTRAN cell can be selected after an intensive search in the EMM-DEREGISTERED state?
Option 1: The UE enters the EMM-DEREGISTERED.NO-CELL-AVAILABLE substate and searches for cells at a low rhythm.
Option 2: The UE enters the EMM-DEREGISTERED.PLMN-SEARCH substate and initiates a new intensive search.
Option 3: The UE deactivates the access stratum due to discontinuous coverage.
Option 4: The UE offers EPS services despite no cell being available.
Explanation: When no E-UTRAN cell can be selected after an intensive search in the EMM-DEREGISTERED state, the UE enters the EMM-DEREGISTERED.NO-CELL-AVAILABLE substate. In this substate, cells are searched for at a low rhythm, and no EPS services are offered. This is because the UE is unable to find a suitable cell to connect to, and therefore cannot provide any EPS services.
