APPARATUS AND METHOD FOR SRv6 TRANSPORT NETWORK INTEGRATION IN WIRELESS COMMUNICATION SYSTEM

A method of operating a UTN Application Function (UTN AF) for integrating a core network and an SRv6 based transport network in a wireless communication system, the method comprising:

• receiving Segment Routing (SR) node information and link information from a Transport Network Controller (TNC);
• configuring a transport network topology based on the received SR node information and link information;
• calculating an optimal path according to service requirements based on the configured topology to generate a Segment Identifier (SID) list;
• delivering the generated SID list to a Policy Control Function (PCF) as policy information;
• and
• delivering policy rules generated by the PCF based on the policy information to a User Plane Function (UPF) and a Radio Access Network (RAN) through a Session Management Function (SMF).

A Unified Transport Network Controller (UTNC) for integrating a core network and a Segment Routing IPv6 (SRv6) based transport network in a wireless communication system, comprising:

• a transceiver;
• and
• a processor operably connected to the transceiver,
• wherein the processor is configured to:
• receive Segment Routing (SR) node information and link information from a Transport Network Controller (TNC);
• configure a transport network topology based on the received SR node information and link information;
• calculate an optimal path according to service requirements based on the configured topology to generate a Segment Identifier (SID) list;
• and
• deliver the generated SID list to a User Plane Function (UPF) and a Radio Access Network (RAN) through a Session Management Function (SMF).
