Abstract
Prioritization of data traffic is a common technique for providing enhanced quality of service (QoS), allowing some traffic to reach its destination on an expedited basis without being obstructed or delayed by other lower-priority traffic. A mechanism is disclosed using the bearer architecture of the evolved packet core (EPC) to provide prioritization of traffic from specific packet data networks (PDNs), as well as over specific bearers. The priority information is requested by the mobile management entity (MME), which is commonly overloaded with traffic to and from multiple users and PDNs. In addition, a mechanism is provided for reducing the frequency of unwanted paging notifications for MMEs that are overloaded.
