Abstract: System and method embodiments are provided for traffic engineering (TE) in software defined networking (SDN). The embodiments enable a complete end-to-end TE solution between a user equipment (UE) and a source/destination across a radio access network (RAN). In an embodiment, a method in a network component for TE in a SDN includes receiving TE information from a first core network component in a core network, a RAN component, wherein the RAN is communicably coupled to the core network, wherein the TE information includes a TE objective; and determining a TE decision between at least one UE and a second core network component in the core network according to the TE information and the TE objective, wherein the TE decision comprises information for at least one end-to-end path solution between the at least one UE and the second core network wherein the path traverses the core network and the RAN.

Abstract: Efficient D2D link integration can be achieved by allowing mobile devices to independently initiate D2D/connection-proxy discovery without re-broadcasting beacons originating from the wireless access point. A mobile station wanting to establish a D2D link may broadcast a search message to neighboring mobile stations, which may return offer messages specifying a connection quality and/or parameters of the candidate indirect connection. The requesting mobile station may then select one of the responding neighboring mobile stations through which to establish the indirect connection. Responding mobile stations may delay offer message transmission by a period that is proportional to a connection quality to reduce offer message redundancy.
