METHODS, APPARATUSES AND SYSTEMS DIRECTED TO PROXIMITY SERVICES (ProSe) DIRECT DISCOVERY

Abstract

Methods, apparatus, systems, devices, and computer program products directed to enhancements to proximity-based services (ProSe) direct discovery are provided. Among the methods is a method that may be implemented in a proximity services (ProSe) function and that may include receiving, from the first WTRU, a first discovery request message including a ProSe application identifier (ID); receiving, from a second WTRU, a second discovery request message including the ProSe application ID; in response to the second discovery request message, transmitting, to the second WTRU, a discovery response message including a discovery filter, wherein the discovery filter includes a first ProSe application code; receiving, from the second WTRU, a match report including a second ProSe application code and a metadata flag; and generating a match report acknowledgement message, wherein the match report acknowledgement message includes (1) a value of a validity timer and (2), based on the metadata flag, metadata information associated with the ProSe application ID, if any.

Dependencies are inferred from the claim text.
