Question: What is the primary objective of the Enhanced Relocation Complete Confirm procedure in the UTRAN Iu interface RANAP signalling?
Option 1: To instruct the Core Network (CN) to switch bearers towards the target Radio Network Controller (RNC) for Circuit Switched (CS) domain services.
Option 2: To request the Mobile Station (MS) to perform handover to a different frequency in the same cell.
Option 3: To notify the Serving RNC about the successful completion of an intra-RNC handover.
Option 4: To initiate the setup of new bearers for Packet Switched (PS) domain services towards the target SGSN.
Explanation: The Enhanced Relocation Complete Confirm procedure is specifically designed to signal the Core Network (CN), but only for Circuit Switched (CS) domain services, to redirect (switch) the bearers towards a new target Radio Network Controller (RNC). This procedure ensures seamless service continuity during relocation in the UTRAN network.
