  • Publication number: 20200187108
    Abstract: A method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons.

  • Publication number: 20170374034
    Abstract: A method for use in a wireless transmit/receive unit (WTRU) for configuring a privacy protocol stack profile, including private addresses for the WTRU is described herein. For example, the WTRU may determine if it is in an unknown location and may set a profile of the WTRU to public network, and may set the MAC and IP addresses and other protocol identifiers to random, opaque and non-persistent. The method also includes receiving information about neighboring networks, which may then be used to determine profile options based on context of the neighboring networks. Available profile options based on the determination may be displayed and selected via a user input. Each layer of a protocol stack may be then instructed to use privacy and security settings based on the selected profile, which may include anonymous or random dynamic host configuration protocol (DHCP) parameters.
