* a) protocol discriminator;
* b) security header type;
* c) message authentication code;
* d) sequence number;
* e) plain NAS message, as defined in item 1.
*
* The EPS bearer identity and the procedure transaction identity are only used in messages
* with protocol discriminator EPS session management. Octet 1a with the procedure transaction
* identity shall only be included in these messages.
