All Bearers Are Rejected Call Flow
This section describes the call flow where PCF rejects all the bearers.

Step |
Description |
---|---|
1 | The SMF sends a N7 Create request to the PCF. |
2 |
The PCF responds to the SMF with the success response. |
3 |
The AF sends an AAR-I (Audio and Video) message to the PCF. |
4 |
The PCF performs the Rx Authorization CRD lookup. |
5 | The Rx Authorization CRD evaluates both, audio and video bearer. If there is a missing Media-Type AVP, PCF rejects the bearer. PCF validates all the bearers for Bearer-Authorization=REJECT. The bearers are classified as unauthorized and are not installed on the SMF. If all bearers received in the AAR are rejected, PCF sends a AAA (5003) Result-Code=DIAMETER_AUTHORIZATION_REJECTED Error-Message=Throttled to the AF. |
