PCRF RULE ROLLBACK DUE TO INSUFFICIENT RESOURCES ON A DOWNSTREAM NODE

摘要

Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN) device. The method may include: establishing a first service data flow for an application function having a first Policy and Control Charging (PCC) rule including a first parameter within a session; receiving a request to upgrade the first parameter of the service data flow; generating a second PCC rule including an upgraded parameter; storing the first PCC rule in a cache; sending the second PCC rule to a Policy and Charging Enforcement Node (PCEN); receiving acknowledgement that the second PCC rule has been installed at the PCEN; receiving an indication that the second PCC rule failed at a downstream node; and sending the first PCC rule stored in the cache to the PCEN.
