Question: What happens to all active Policy and Charging Control (PCC) rules associated with an IP-CAN bearer when that bearer terminates?
Option 1: They are automatically modified to apply to another available IP-CAN bearer.
Option 2: They remain active until explicit instructions are received from the Policy and Charging Rules Function (PCRF).
Option 3: Their activation is deferred until the next IP-CAN session establishment.
Option 4: They are deactivated without requiring explicit instructions from the PCRF.
Explanation: According to telecom standards for Policy and Charging Control architecture, when an IP-CAN bearer terminates, all active PCC rules associated with that bearer are automatically deactivated. This process does not require explicit deactivation instructions from the PCRF, ensuring seamless management of network resources upon bearer termination.
