The conditional 'AUTS' and 'RAND' IEs are both present in case the SIM (via UE) requests an UMTS AKA re-synchronization procedure. Either both optional IEs are present, or none of them.

+The conditional 'PDP Info' IE is only present in the CEAI interface used by the ePDG. It should contain the 'PDP Context ID', 'PDP Address' (dynamic addressing) and 'Access Point Name' IEs. + [[gsup-msg-auth-info-err]] ==== Send Authentication Info Error
