Version     0.1

Date        2012/10/03

Product     NAS stack

Subsystem   EPS Mobility Management

Author      Frederic Maurel

Description Implements the EPS Mobility Management procedures executed
        when the EMM-SAP is in EMM-REGISTERED.UPDATE-NEEDED state.

        In EMM-REGISTERED.UPDATE-NEEDED state, the UE has to perform
        a tracking area updating or combined tracking area updating
        procedure, but access to the current cell is barred. The access
        class may be blocked due to access class control, or the
        network rejected the NAS signalling connection establishment.
        No EMM procedure except tracking area updating or combined
        tracking area updating or service request as a response to
        paging shall be initiated by the UE in this substate.
