Method to mitigate fraudulent usage of QoS from mobile terminals using uplink packet marking

An access gateway (AGW) to affect the passage of transmitted messages over traffic priority flow according to associated quality of service (QoS), the access gateway comprising logic for:

• receiving, from a network element, at least one uplink filter parameter;
• receiving a message using a traffic flow, from a user equipment (UE), including an indicator of an actual priority at an access point (AP), wherein the actual priority is determined at the UE according to a message characteristic and the at least one uplink filter parameters, and is associated with the used traffic flow;
• using the at least one uplink filter parameter to determine an expected priority of the message;
• and
• determining access based on comparing the expected priority and the actual priority of the message.

A computer-readable medium comprising instructions for providing a service to a wireless terminal, the instructions for causing performance of a method comprising:

• receiving, from a network element, at least one uplink filter parameter;
• receiving a message using a traffic flow, from a user equipment (UE), including an indicator of an actual priority at an access point (AP), wherein the actual priority is determined at the UE according to a message characteristic and the at least one uplink filter parameters, and is associated with the used traffic flow;
• using the at least one uplink filter parameter to determine an expected priority of the message;
• and
• determining access based on comparing the expected priority and the actual priority of the message.
