Fault Identification

When VIP subscribers go online, an improved QoS is provided. After a radio network controller (RNC) handover, the QoS provided for the VIP subscribers deteriorates, causing a failure in providing a QoS guarantee for VIP subscribers.

Troubleshooting Method

QoS negotiation parameters are set incorrectly. To resolve this issue, modify the value of the QoS-Negotiation AVP on the serving GPRS support node (SGSN).

Troubleshooting Procedure

Check the subscriber message tracing results to see whether the QoS-Negotiation AVP in a credit control request-update (CCR-U) message is set to 0, which indicates that a QoS negotiation is not allowed for the corresponding policy and charging control (PCC) rule request.

Yes: Go to 2.
No: Contact Huawei technical support engineers.
