1. A first wireless transmit/receive unit (WTRU) comprising:
a processor, a transmitter, a receiver, and a memory configured to:
receive, from a second WTRU, a first message requesting a forwarding identifier (FID) associated with a fully qualified domain name (FQDN) of a service function (SF), the first message including a SF identifier (SFID) associated with the FQDN of the SF, and a SF endpoint identifier (SFEID) associated with the FQDN of the SF;
identify a subscriber associated with the SFID in a first namespace of subscribers;
determine whether the SFEID is available in a second namespace; and
based on the SFEID being available in the second namespace, send a second message to the second WTRU indicating the FID associated with the FQDN of the SF.
