|
|
* Within the protocols defined in the present document, every message, except the SERVICE REQUEST message,
|
|
* is a standard L3 message as defined in 3GPP TS 24.007 [12]. This means that the message consists of the following parts:
|
|
* 1) if the message is a plain NAS message:
|
|
* a) protocol discriminator;
|
|
* b) EPS bearer identity or security header type;
|
|
* c) procedure transaction identity;
|
|
* d) message type;
|
|
* e) other information elements, as required.
|
|
* 2) if the message is a security protected NAS message:
|
|
* 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.
|
|
*/
|
|
|
|
/*
|
|
* All messages received here will have the security header:
|
|
* Figure 9.1.2: General message organization example for a security protected NAS message
|
|
* 9.3.1 Bits 5 to 8 of the first octet of every EPS Mobility Management (EMM)
|
|
* message contain the Security header type IE.
|
|
* 4.4.4.2 All ESM messages are integrity protected.
