All Bearers Are Rejected Call Flow
All Bearers Are Rejected Call Flow Description

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.
