Question: In Inter-V2X Control Function Signalling, what is the implication of setting the Auth-Session-State AVP to NO_STATE_MAINTAINED (1) in Diameter sessions between V2X Control Functions?
Option 1: The server maintains state information for an extended period, and the client must send periodic re-authorization requests.
Option 2: The client is prohibited from sending any further requests after the initial response from the server.
Option 3: The Authorization-Lifetime AVP and Session-Timeout AVP become mandatory in all subsequent requests and responses.
Option 4: The server does not maintain state information about the session, and the client does not send session termination or re-authorization requests.
Explanation: Setting the Auth-Session-State AVP to NO_STATE_MAINTAINED (1) indicates an implicitly terminated session. This means the server will not keep any state information regarding this session, and as a result, there is no need for the client to send requests for session termination or re-authorization, aligning with efficient resource management in V2X communication scenarios.
