METHOD TO MITIGATE FRAUDULENT USAGE OF QOS FROM MOBILE TERMINALS USING UPLINK PACKET MARKING

摘要

A method is provided for mapping between an uplink traffic characteristic and a transmission prioritization level to prevent fraudulent access to priority flows at a centralized point in a network. According to certain embodiments, an Access Gateway (AGW)receives at least one network filter parameter from a network element, which indicates expected priorities. The User Equipment (UE)transmits a messageover a traffic flow to an Access Point (AP), including an indicator of the actual priority at the AP. The message isforwarded to an AGW. The actual priority is determined at the user equipment according to a message characteristic and an uplink filter parameter, which is associated with the traffic flow that was used for transmission. Access to priority flows is determined based on comparing the expected priority and the actual priority of the message.
