Question: What is the primary purpose of the MMEC (MME Identifier) Information Element in E-UTRA Radio Resource Control (RRC) protocol?
Option 1: To uniquely identify a User Equipment (UE) within a Public Land Mobile Network (PLMN)
Option 2: To differentiate between various E-UTRAN Node B (eNodeB) within a cell
Option 3: To indicate the quality of service for a specific bearer in the Evolved Packet System (EPS)
Option 4: To identify an Mobility Management Entity (MME) within the scope of an MME Group in a PLMN
Explanation: The MMEC Information Element is designed to identify an MME, crucial for managing mobility and session management, within a group of MMEs in a Public Land Mobile Network (PLMN), ensuring efficient routing of signaling messages and proper handling of UE contexts.
