Device to device (D2D) communication mechanisms
First Claim
1. At least one non-transitory computer readable medium having instructions stored thereon for enabling device-to-device (D2D) communication in a wireless network, the instructions when executed on a machine to cause the machine to:
- receive a traffic flow optimization message at a first transmission node in the wireless network from a detection function (DF) module operating in an evolved packet core (EPC), wherein the DF module is stored in a digital memory device or is implemented in a hardware circuit; and
establish a backhaul link between the first transmission node and a second transmission node in the wireless network, wherein the D2D communication includes the backhaul link; and
transmit a D2D setup message from the first transmission node to establish a D2D link to provides communication between a first wireless device and a second wireless device via the backhaul link between the first transmission node and the second transmission node, thereby bypassing the serving gateway (SGW) for the D2D communication, wherein the first wireless device is in communication with the first transmission node, and the second wireless device is in communication with the second transmission node.

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.
