Question: In a Policy and Charging Control (PCC) architecture, what is a requirement for establishing a session related to the Gxx application using Diameter protocol?
Option 1: A single Diameter session can support multiple Gateway Control sessions.
Option 2: A separate Diameter session must be established for each Gateway Control session.
Option 3: The Gxx application identifier is not required in the Auth-Application-Id AVP for session establishment.
Option 4: Only the Diameter Base Protocol AVPs are used without any specific AVPs for the Gxx application.
Explanation: This is correct because, according to the specifications, a diameter session needs to be established for each Gateway Control session specifically in the context of the Gxx application. This ensures that each Gateway Control session has a dedicated Diameter session, which is crucial for managing and controlling policy and charging rules effectively in telecom networks.
