Question: What is the primary purpose of the SLSSID (SLSSID Information Element) in E-UTRA Radio Resource Control (RRC) protocol?
Option 1: To authenticate User Equipment (UE) during initial network attachment.
Option 2: To manage Quality of Service (QoS) for dedicated bearers in a cell.
Option 3: To synchronize handover procedures between neighboring eNodeBs.
Option 4: To enable detection of asynchronous neighboring cells by the UE and extend synchronization signals beyond the cell's coverage.
Explanation: The correct answer reflects the dual role of SLSSID: (1) aiding UEs in detecting asynchronous neighboring cells for seamless handovers, and (2) facilitating the extension of synchronization signals to ensure smoother transitions between cells. The other options describe unrelated functions.
