* Step 1: The UE shall send the initial NAS message to the AMF.
|
|
|
|
* If the UE has no NAS security context, the initial NAS message
|
|
|
|
* shall only contain the cleartext IEs, i.e. subscription identifiers
|
|
|
|
* (e.g. SUCI or GUTIs), UE security capabilities, ngKSI, indication
|
|
|
|
* that the UE is moving from EPC, Additional GUTI, and IE containing
|
|
|
|
* the TAU Request in the case idle mobility from LTE.
|
|
|
|
*
|
|
|
|
* If the UE has a NAS security context, the message sent shall contain
|
|
|
|
* the information given above in cleartext and the complete initial
|
|
|
|
* NAS message ciphered in a NAS container which is ciphered.
|
|
|
|
* With a NAS security context, the sent message shall also be
|
|
|
|
* integrity protected. In the case that the initial NAS message
|
|
|
|
* was protected and the AMF has the same security context,
|
|
|
|
* then steps 2 to 4 may be omitted In this case the AMF shall
|
|
|
|
* use the complete initial NAS message that is in the NAS container
|
|
|
|
* as the message to respond to.

* - Extended protocol discriminator;
