Question: What is the primary purpose of the Enhanced Relocation Complete procedure in the UTRAN Iu interface Radio Access Network Application Part (RANAP) signalling?
Option 1: To inform the Core Network (CN) that resources have been allocated by the target Radio Network Controller (RNC), enabling user plane switching.
Option 2: To initiate handover from the source RNC to the target RNC without resource allocation.
Option 3: To release resources at the source RNC after a successful handover.
Option 4: To establish connectionless signalling between the CN and the target RNC.
Explanation: The Enhanced Relocation Complete procedure's main goal is to notify the Core Network (CN) that the target Radio Network Controller (RNC) has successfully allocated necessary resources, enabling the CN to switch the user plane to the target RNC for seamless communication continuity during relocation.
