Question: Which of the following best describes the primary distinction between X2AP Basic Mobility Procedures and X2AP Global Procedures in the context of E-UTRAN?
Option 1: X2AP Basic Mobility Procedures involve interactions with a single eNB, while X2AP Global Procedures coordinate actions between two peer eNBs.
Option 2: X2AP Basic Mobility Procedures are used for UE mobility within a single cell, whereas X2AP Global Procedures manage handovers between different E-UTRAN networks.
Option 3: X2AP Basic Mobility Procedures focus on UE signaling, and X2AP Global Procedures concentrate on eNB configuration management.
Option 4: X2AP Basic Mobility Procedures handle non-UE related signaling, while X2AP Global Procedures are specifically designed for UE mobility management within E-UTRAN.
Explanation: The correct answer highlights the key difference between the two procedure modules. X2AP Basic Mobility Procedures primarily deal with handling User Equipment (UE) mobility within E-UTRAN, typically involving a single eNB's direct management or interaction for each UE's mobility event. In contrast, X2AP Global Procedures imply a broader scope that includes coordination between two peer eNodeBs (eNBs) for procedures not centered around individual UE mobility, such as load management or general network optimization strategies.
