Option 1: Only Usage Monitoring
Option 2: Gating, Redirection, and Bandwidth Limitation, but not Charging
Option 3: Charging, but not Gating, Redirection, or Bandwidth Limitation
Option 4: Gating, Redirection, Bandwidth Limitation, and Charging
Explanation: According to the specifications for Solicited Application Reporting, when the service data flow description cannot be provided by the TDF to the PCRF, the TDF can perform additional actions beyond mere reporting. These include Gating (controlling access), Redirection (diverting traffic), Bandwidth Limitation (restricting speed), and Charging (applying billing rules) for the detected applications, as instructed by the PCRF.
