Question: Which of the following best describes the primary purpose of the Serving RNS Relocation function in a UTRAN network?
Option 1: To manage handovers between different Radio Access Technologies (RATs)
Option 2: To relocate the Serving RNS functionality to a different RNC, typically closer to the User Equipment's (UE) new location
Option 3: To optimize resource allocation within a single RNC for multiple UEs
Option 4: To facilitate direct communication between the Core Network (CN) and User Equipment (UE)
Explanation: The correct answer, Option 2, accurately reflects the primary purpose of Serving RNS Relocation. This function enables the transfer of the Serving Radio Network Controller (RNC) functionality to another RNC, usually in response to the UE's movement to a new location, enhancing network efficiency and reducing latency.
