DISCOVERY AND OPERATION OF HYBRID WIRELESS WIDE AREA AND WIRELESS LOCAL AREA NETWORKS
First Claim
1. A method for establishing device to device (D2D) communication in a hybrid wireless network, comprising:
- identifying a proximity of a first user equipment (UE) with a second UE using a wireless wide area network (WWAN);
communicating network assisted proximity discovery information to the first UE and the second UE, wherein the proximity discovery information includes a D2D communication channel;
establishing a D2D communication link between the first UE and the second UE using a wireless local area network (WLAN) based D2D format on the D2D communication channel.

Abstract
Technology for setting up a Device to Device (D2D) communication channel between mobile wireless devices is disclosed. The technology includes identifying a first user equipment and a second user equipment located within a proximity; receiving network assisted proximity discovery information at one of the first UE and the second UE from an evolved packet core (EPC) operating on a third generation partnership practice (3GPP) wireless wide area network (WWAN); and setting up a device to device (D2D) communication between the first UE and the second UE based on the network assisted proximity discovery information received from the EPC.

14. A module operable to establish device to device (D2D) communication, comprising:
a proximity detection function (PDF) module in communication with a third generation partnership project (3GPP) configured wireless wide area network (WWAN), wherein the PDF module is configured to; identify when a first user equipment (UE) and a second UE are located within proximity; select one of the first UE and the second UE as a peer to peer (P2P) group owner; and communicate selected network assisted proximity discovery information to the first UE and the second UE based on the P2P group owner. - View Dependent Claims (15, 16, 17, 18)

19. A user equipment configured to setup a device to device (D2D) communication, comprising:
a device to device (D2D) module operating on the UE and configured to communicate with a proximity detection function (PDF) module in communication with a third generation partnership project (3GPP) wireless wide area network, wherein the D2D module is configured to; receive an indication from the PDF module that another UE is located within proximity of the UE; receive network assisted proximity discovery information from the PDF module that can be used to establish a D2D communication with the other UE, including a D2D communication channel; receive a peer to peer (P2P) group owner status from the PDF module; and setup the D2D communication on the D2D communication channel with the other UE using the network assisted proximity discovery information based on the P2P group owner status. - View Dependent Claims (20, 21, 22, 23, 24, 25)
