name: NAS
full_form: Non Access Stratum
context: Editorâs Note: It is ffs how the key changes on one NAS connection, e.g. following a NAS SMC on one leg, are propagated to the other NAS connection. The NAS CONN ID is a number that is incremented each time a new NAS connection is set up. In the security context, each NAS COUNT pair is associated to a unique NAS CONN ID value. The new parameter is used as the differentiator when interacting with the NAS security function to indicate which NAS connection each message belongs. To keep track of unallocated NAS CONN ID values, an additional parameter is needed. This new parameter, denoted by NEXT NAS CONN ID is also part of the security context. The NEXT NAS CONN ID parameter is initially set to 0 and is incremented whenever a new NAS connection is set up. Each time a new NAS connection is created, it is allocated as identifier the current NEXT NAS CONN ID value. More precisely, a new pair of NAS COUNT is created and is associated to a NAS CONN ID whose value is set to the current NEXT NAS
description: The Non-Access Stratum (NAS) protocol manages communication between the User Equipment (UE) and the Mobility Management Entity (MME) in the Evolved Packet System (EPS). It handles signaling for mobility management, session management, and authentication.
explanation: The text describes NAS as managing connections, identifiers, and associations within the EPS network. This points to NAS being a set of rules governing data transmission, a key characteristic of a protocol.
