Patent ID: 11996995

Abstract:
Disclosed herein is a method for evaluating data traffic in a communication network. The method comprising establishing a protocol session between a control plane, CP, node and a user plane, UP, node and configuring, by the CP node, a first detection rule to be used for event notification, and at least one next detection rule to be used for traffic detection. The first detection rule comprises an indicator indicating the highest precedence, and identifies a first instruction rule indicating an event to be notified and a continuation flag indicating evaluation of at least one next detection rule. The at least one next detection rule comprises an indicator indicating a lower precedence than the one in the first detection rule and identifies a next instruction rule to be applied to a matched traffic. The method also comprises determining, at the UP node and based on the continuation flag, whether the received packet matches any detection rule amongst the at least one next detection rule from higher to lower precedence.
