Abstract
Technology for establishing a device to device (D2D) connection is disclosed. One device comprises a UE that includes a proximity discovery module configured to receive discovery information from at least one of a wireless wide area network (WWAN) and a wireless local area network (WLAN) to assist in establishing a D2D communication channel with at least one additional UE. A D2D communication module is configured to establish the D2D communication channel between the UE and the at least one additional UE using the discovery information. The D2D communication channel is established in a licensed radio frequency band and is managed by the WWAN.
