Question: In a Policy and Charging Control (PCC) architecture, when the Redirect-Information AVP includes the Redirect-Server-Address AVP, what additional information must also be provided?
Option 1: Charging-Rule-Name AVP to identify the charging rule
Option 2: Redirect-Address-Type AVP to indicate the type of address
Option 3: Application-Id AVP to specify the targeted application
Option 4: QoS-Parameters AVP to define the quality of service
Explanation: According to PCC standards, when the Redirect-Server-Address AVP is included in the Redirect-Information AVP, it is necessary to also provide the Redirect-Address-Type AVP. This is crucial for indicating the type of address (e.g., IP address, URL, etc.) given in the Redirect-Server-Address AVP, ensuring proper redirection of detected application traffic.
