Abstract: A method, system and compute readable media for Quality of Service (QoS) Class Identifier (QCI) based traffic-offload of Packet Data Network (PDN) traffic at a trusted Wireless Fidelity (WiFi) access gateway are presented. In one embodiment a method includes for an initial attachment of a User Equipment (UE) via a Trusted Wireless Access Network (TWAN): providing TWAN the QCI value in an Attribute Value Pair (AVP) in an Access point Network (APN)-Configuration AVP; using by a Trusted Wireless Access Gateway (TWAG) a QoS profile while requesting for default bearer creation with Packet Data Network Gateway (PGW) using General Packet Radio Service Tunneling Protocol (GTP)V2 Create Session Request; responding, by the PGW, with a final QoS profile based on various parameters; and making a determination if the QCI equals a QCI offload (QCIo) and routing traffic in accordance with the determination.
