Question: What is the primary purpose of the NAS Transport procedure in the context of E-UTRAN (Evolved Universal Terrestrial Radio Access Network)?
Option 1: To interpret and process UE signaling at the eNB level for enhanced network security.
Option 2: To carry UE – MME signalling over the S1 Interface without interpreting NAS messages at the eNB.
Option 3: To establish a direct communication link between the UE and the eNB, bypassing the MME.
Option 4: To manage the allocation of radio resources for UE connections within the E-UTRAN.
Explanation: The NAS Transport procedure's main goal is to transport UE - MME signaling messages over the S1 Interface, without interpreting these NAS messages at the eNB, emphasizing a clear separation of responsibilities within the E-UTRAN architecture.
