Abstract: A method for setting up a multiple radio access technology (multi-RAT) device-to-device (D2D) communication is disclosed. An application function (AF) in a wireless transmit/receive unit (WTRU) may identify a group of multiple radio access technology (multi-RAT) capable WTRUs to a policy control function (PCF), wherein one or more multi-RAT capable WTRUs of the group of multi- RAT capable WTRUs register as having enhanced device-to-device (ED2D) functionality. The AF may select a multi-RAT capable WTRU from the group of multi-RAT capable WTRUs having ED2D functionality, as a relay for extended D2D operation. The device with ED2D function will act as Relay for ED2D (RED2D). The PCF may then reconfigure the RED2D with group related information. The RED2D may then configure D2D communication among the group of multi-RAT capable WTRUs.

Abstract: Methods, apparatus, systems, architectures and interfaces for a wireless transmit receive unit (WTRU) performing a client-side edge resolution function (cERF) are provided. A method may include any of: determining a fully qualified domain name (FQDN) associated with a domain name server (DNS) request of an application associated with the WTRU; if the FQDN is associated with a valid edge instance (EI) record, selecting an EI for resolving the FQDN to an IP address; if the FQDN is not associated with a valid EI record: (1) transmitting a DNS query to a DNS server, (2) receiving an IP address associated with a selected EI to which the FQDN is resolved, and (3) updating the EI record with the IP address and the FQDN; and generating a traffic steering rule to re-direct uplink traffic associated with the application to the selected EI.

Abstract: Methods and apparatuses for discovery and selection of a Local Network Exposure Function (L-NEF) are described herein. A method of for registering with a Network Repository Function (NRF) performed by a L-NEF may include sending, to the NRF, a register registration message that includes a new NF network function (NF) profile, the new NF profile further including an identification of a Local Area Data Network (LADN), Service area information associated with the L-NEF, and a User Plane Function (UPF) Identifier (ID). The method may include receiving a registration response message from the NRF.
