Question: In the context of 5G System Network Exposure, what is the primary purpose of the procedures for ECS (Emergency Communication Services) Address Configuration Information provisioning in roaming scenarios between an Application Function (AF) and a V-NEF (Virtualized Network Exposure Function)?
Option 1: To manage UE (User Equipment) authentication credentials across different PLMNs (Public Land Mobile Networks).
Option 2: To facilitate the exchange of ECS Address Configuration Information for emergency services in visited networks.
Option 3: To authorize, create, update, or delete AF-provisioned ECS Address Configuration Information stored in the V-UDR (Virtualized Unified Data Repository).
Option 4: To optimize network resource allocation for roaming subscribers using ECS.
Explanation: The correct answer is Option 3 because the procedures outlined are specifically designed for the AF to manage (create, update, delete) ECS Address Configuration Information and for the V-NEF to authorize these changes to be reflected in the V-UDR. This process ensures that emergency communication services' configuration information is accurately and securely updated across network functions, especially crucial in roaming scenarios where the user's device may need to access emergency services in a visited network.
