Question: What is the primary action taken by the H-PCRF upon receiving a Sy Session Termination Request from the OCS, in the context of Policy and Charging Control architecture?
Option 1: The H-PCRF immediately terminates all active sessions (Sy, Rx, Gx) associated with the subscriber.
Option 2: The H-PCRF removes the Sy session context of the subscriber and makes applicable policy decisions that may affect other interfaces (Rx, Gx).
Option 3: The H-PCRF sends a notification to the subscriber's device to manually terminate the Sy session.
Option 4: The H-PCRF ignores the request if there are ongoing sessions on other interfaces (Rx, Gx).
Explanation: This is correct because, upon receiving a Sy Session Termination Request, the H-PCRF removes the Sy session context and makes applicable policy decisions based on this termination, which may affect other interfaces (like Rx or Gx), ensuring a controlled termination process.
