About LTE NAS
LTE NAS carries mobility and session signaling between UE and core network functions. Initial header bytes identify security context, NAS domain, and message identity.
Non-Access Stratum signaling carries LTE mobility and session management procedures between UE and core network entities. Basic NAS header decoding is useful for attach/authentication flow triage.
LTE NAS Header Structure
- Security Header Type (4 bits): NAS protection/context indicator.
- Protocol Discriminator (4 bits): EMM or ESM signaling family.
- Message Type (1 byte): specific NAS procedure message.
