Question: Which entity/entities can initiate the AN Release procedure via W-5GAN access to release the logical NG-AP signalling connection in a 5G System (5GS) setup?
Option 1: Only the User Equipment (UE)
Option 2: Either the W-5GAN or the Access and Mobility Management Function (AMF)
Option 3: Only the 5G Core Network (5GC) itself
Option 4: Both the UE and the 5GC simultaneously
Explanation: In a Wireless and wireline convergence access support for the 5G System, the AN Release procedure is crucial for managing resources efficiently. The correct answer highlights that either the W-5GAN or the AMF can initiate this release, allowing for better network management whether it's the access network or the core network's management function adjusting resource allocations.
