Abstract
A system, apparatus, and method for providing proximity services (ProSe) registration, proximity request, proximity alert, proximity request cancellation, and deregistration handling between a wireless device and a ProSe function of a cellular core network using session initiation protocol. A wireless device and a ProSe function of a cellular core network may exchange SIP signaling messages to register and de-register the wireless device for cellular network assisted proximity services. The wireless device and the ProSe function may further (while the wireless device is registered) exchange SIP signaling messages to request proximity alerts, provide proximity alerts, and request cancellation of proximity alert requests.
