Author      Frederic Maurel

Description Implements the EPS Mobility Management procedures executed
        when the EMM-SAP is in EMM-REGISTERED.NO-CELL-AVAILABLE state.

        In EMM-REGISTERED.NO-CELL-AVAILABLE state, E-UTRAN coverage
        has been lost. The UE shall not initiate any EMM procedures
        except for cell and PLMN reselection.
