PRESERVATION OF POLICY AND CHARGING FOR A SUBSCRIBER FOLLOWING A USER-PLANE ELEMENT FAILOVER

摘要

Techniques that provide for the preservation of policy and charging for a subscriber following a user-plane element failover are described herein. In one embodiment, a method includes receiving, by a user-plane element, at least one data packet of a packet flow associated with a subscriber, wherein the at least one data packet is received after the user- plane element has recovered from a failure; determining, by the user-plane element, whether restoration information associated with the packet flow is stored at the user-plane element; and applying one or more policies to the packet flow based on a determination that the restoration information associated with the packet flow is stored at the user-plane element, wherein the restoration information comprises a rule associated with the packet flow.
