Methods and apparatuses for handling of network functions deployed in a customer premise network

A wireless transmit/receive unit (WTRU) for wireless communications, comprising circuitry, including a processor, a transmitter, a receiver, and memory, the WTRU configured to:

• send, to an access and mobility management function (AMF), a first registration message indicating a request for the AMF to proxy register a network function (NF) or an NF group associated with the WTRU;
• receive, from the AMF, a second registration message indicating proxy registration information based on the first registration message;
• and
• send, to the AMF, a message indicating NF profile information of the NF or the NF group associated with the WTRU.

A network device comprising:

• a processor configured to:
• receive a registration message from a wireless transmit/receive unit (WTRU), wherein the registration message indicates a request for the network device to proxy register a network function (NF) or an NF group associated with the WTRU;
• send a registration accept message to the WTRU;
• receive a network function (NF) profile message from the WTRU, wherein the NF profile message indicates NF profile information for the NF or the NF group associated with the WTRU;
• receive an internet protocol (IP) address assignment, wherein the IP address assignment indicates IP address information associated with the WTRU;
• update the NF profile information based on the IP address information;
• and
• perform proxy registration for the NF or the NF group associated with the WTRU based on the updated NF profile information.
