Abstract

Technology for enabling device-to-device (D2D) communication in a wireless network is disclosed. One method comprises receiving a traffic flow optimization message at a first transmission node in the wireless network from a detection function (DF) module. A D2D setup message can be transmitted from the first transmission node to establish a D2D link, wherein the D2D link bypasses a serving gateway for the wireless network and provides communication between a first wireless device and a second wireless device.
