Qos-Group-of-Ruledef Modification Call Flow
Call Flow Description for Modification of QoS Group of Ruledefs
Step Description
1

Once qos-group-of-ruledefs is activated, PCF modifies the QoS parameters through ‘QoSGroupRuleName’ IE sent in SM policy association establishment response and SM policy association update request from N7 messages.

PCF triggers “Modify 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 SMF prepares Update FAR and QER for each QGR received for modification and encodes the activated QoS group names along with the corresponding FAR IDs and QER IDs in QGR-INFO-LIST to be sent on N4 session establishment or modification request.
