Question: How are Diameter sessions managed between the Gateway Mobile Location Centre (GMLC) and the Home Subscriber Server (HSS) on the SLh interface, specifically regarding state maintenance?
Option 1: Explicitly terminated with maintained state, using Authorization-Lifetime and Session-Timeout AVPs.
Option 2: Implicitly terminated with no state maintained, utilizing the Auth-Session-State AVP set to NO_STATE_MAINTAINED.
Option 3: Through periodic re-authentication sessions, with the client initiating session termination requests.
Option 4: By leveraging Accounting Session State Machine functionality.
Explanation: This is correct because Diameter sessions between the GMLC and HSS are implicitly terminated, meaning the server does not maintain state information. This is achieved by including the Auth-Session-State AVP set to NO_STATE_MAINTAINED in requests and responses, ensuring no state maintenance.
