Techniques for non-integrated traffic aggregation, steering, and switching for a protocol data unit session

A method of wireless communication performed by a network node, comprising:

• receiving policy and charging control (PCC) rules that include control information associated with a request to establish a non-integrated aggregation (NIA) protocol data unit (PDU) session, by a user equipment (UE), wherein the PCC rules are based at least in part on one or more proxy types that the UE supports using to steer traffic associated with the NIA PDU session, wherein the one or more proxy types each correspond to two or more Internet Protocol (IP) addresses;
• communicating, to the UE, one or more access traffic steering, switching, and splitting (ATSSS) rules that are derived from the PCC rules, wherein the one or more ATSSS rules are for controlling traffic steering, switching, and splitting associated with the NIA PDU session in an uplink direction;
• and
• communicating, to a user plane function (UPF), N4 interface rules that are derived from the PCC rules, wherein the N4 interface rules are for controlling traffic steering, switching, and splitting associated with the NIA PDU session in a downlink direction.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit, over a wireless access link, a request to establish a non-integrated aggregation (NIA) protocol data unit (PDU) session, wherein the request includes access traffic steering, switching, and splitting (ATSSS) capability information indicating one or more proxy types that the UE supports using to steer traffic associated with the NIA PDU session, wherein the one or more proxy types each correspond to two or more Internet Protocol (IP) addresses;
• and
• receive, over the wireless access link, a message indicating that the NIA PDU session was established and including one or more ATSSS rules for controlling traffic steering, switching, and splitting associated with the NIA PDU session.
