Question: What is the primary objective of the Initial Context Setup procedure in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: To perform a handover from one base station to another, ensuring seamless connectivity for User Equipment (UE).
Option 2: To manage and allocate radio resources efficiently among multiple UEs within a cell.
Option 3: To establish the initial UE Context, including E-RAB context, Security Key, Handover Restriction List, UE Radio capability, and UE Security Capabilities.
Option 4: To initiate a billing process for data services used by the UE on the network.
Explanation: The correct answer is Option 3 because the Initial Context Setup procedure is specifically designed to set up the foundational elements necessary for a User Equipment's (UE) interaction with the E-UTRAN, encompassing not just the radio and security aspects but also ensuring the network is aware of the UE's capabilities. This setup is crucial for subsequent communication processes, making Option 3 the most accurate response in the context of E-UTRAN operations.
