Call Flow Description for Activation of QoS Group of Ruledefs
Step Description
1

PCF activates the qos-group-of-ruledefs through the custom IE ‘QosGroupRuleDefs’ received in N7 messages. The QosGroupRuleDefs IE comprises QosGroupRuleName, refQosGroupQosData, FlowStatus, and Precedence.

PCF triggers “Add QGR” by sending QosGroupRuleName as key and QosGroupRuleDef as value (with all attributes) in QGRDefs map.

PCF sends the QosGroupRuleDefs IE to the SMF through N7 Policy association establishment response or policy association update request message.

2 The SMF prepares Create FAR and QER for each QGR received from PCF and encodes QoS group names along with the corresponding FAR IDs and QER IDs in QGR-INFO-LIST IE to be sent on N4 interface session establishment or modification request.
