Network assistance for device-to-device discovery
First Claim
1. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to:
- receive proximity-based service registration requests from a first user equipment (UE) and a second UE of a first wireless network;
receive a proximity request from the first UE, the proximity request comprising a request for notification when the second UE is proximate to the first UE for direct communication with the second UE via a second wireless network different than the first wireless network, wherein the proximity request received from the first UE comprises a first hypertext transfer protocol (HTTP) message;
receive UE location information from the first UE and the second UE;
detect when the second UE is proximate to the first UE based, at least in part, on the received UE location information from the first UE and the second UE; and
in response to a detection that the second UE is proximate to the first UE, transmit an alert to the first UE as a response to the received proximity request, wherein the alert transmitted to the first UE comprises a second HTTP message.

Abstract
Embodiments of system and method configurations for device discovery and connection establishment in connection with use of device-to-device (D2D) and proximity-based services are generally described herein. In some examples, an evolved packet core (EPC) of a 3GPP Long Term Evolution or 3GPP Long Term Evolution-Advanced (LTE/LTE-A) network is arranged to assist D2D identification and discovery procedures at user equipment (UEs) connected to the LTE/LTE-A network. Various identification and discovery procedures may be implemented in connection with proximity detection and the establishment of communication times for the establishment of the D2D communication link, between the UEs. Accordingly, the EPC of the LTE/LTE-A network may assist the establishment of a device-to-device communication link between UEs on a wireless network employing a distinct wireless protocol (for example, a direct wireless network connection via a wireless local area network (WLAN) or wireless personal area network (WPAN)).

8. Processing circuitry comprising:
-
location detection circuitry to detect whether a first user equipment (UE) and a second UE of a first wireless network are proximate based, at least in part, on received UE location information from the first UE and the second UE; receiver circuitry to; receive proximity-based service registration requests from the first UE and the second UE; receive UE location information from the first UE and the second UE; and receive a proximity request from the first UE, the proximity request comprising a request for notification when the second UE is proximate to the first UE for direct communication with the first UE via a second wireless network, wherein the proximity request received from the first UE comprises a first hypertext transfer protocol (HTTP) message; and transmission circuitry to, in response to a detection that the second UE is proximate to the first UE, transmit an alert to the first UE as a response to the received proximity request, wherein the alert transmitted to the first UE comprises a second HTTP message. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An apparatus for a user equipment (UE) comprising:
-
one or more processors; and software to be executed via the one or more processors to; transmit a registration request to a proximity-based service function of a wireless network; transmit a proximity request to the proximity-based service function, the proximity request comprising a request for notification when a second UE is proximate to the UE for direct communication with the second UE via a wireless local area network (WLAN); receive a response from the proximity-based service function, the response comprising an alert that the second UE is proximate to the UE and a WLAN peer-to-peer (P2P) device identifier for the second UE; and establish a WLAN P2P connection with the second UE using the WLAN P2P identifier for the second UE. - View Dependent Claims (17, 18, 19, 20, 21)
