5 network core and enhance the QoS. This claim is logical since more than 75% of the **data** that traverse the network are delivered to the Internet network. Mobility Management Entity (MME) will have direct fast access to each User Terminal (UT) and with the aid of NI unit it will be able to predict UT future positions. Switching GateWay (SGW) can cooperate with upper VN SGW to quickly switch any connection to its destination. The distributed EPC proves its ability to reduce E2E delay, backhaul overhead, and QoS.
