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)).
