and a subscriber awareness module (Qiao ¶0050: any device can compromise any of the devices in an LTE, 5G, or similar networks, e.g. an SMF) configured to map subscribers (Qiao ¶0223: SMF may map information received from AMF, step 2206) to traffic flows (Qiao ¶0223: SMF may map information based on received information from the NEF, step 2202), based on the received traffic flow parameters (Qiao ¶0222: 2206 may contain S-NSSAI) and subscriber parameters (Qiao ¶0222: 2206 may contain PDU session ID; Qiao teaches an SMF mapping configuration information from traffic flow information, including multiple sessions, and an ID), wherein the SMF event subscription and processing module (Qiao ¶0244: SMF) is configured to receive events on session creates (Qiao Fig. 23: 2306), session updates (Qiao Fig. 23: 2307, Namf_PDUSession_CreateSMContext) and deleted sessions related to the subscriber (Qiao Fig. 18A: 1807, Policy Delete Request) and for processing these received events (Qiao ¶0244: perform secondary authorization) to determine any changes to the subscriber mapping (Qiao ¶0244: SMF may trigger a PDU session establishment authentication and/or authorization; Qiao teaches the SMF receiving a PDU relating to session establishment or authentication, and, that the SMF can be used in response to a policy deletion request).
Qiao does not explicitly teach
at least one processing module configured to request and receive information of traffic flow parameters and subscriber parameters for the traffic flows from the at least one network function, wherein the traffic flow parameters and subscriber parameters comprise Subscriber Identification determined via attributes seen on a data plane of the computer network and location of a subscriber;
However, Jun teaches
at least one processing module (Jun Fig. 10: 310, AMF) configured to request (Jun Fig. 10: S1003) and receive information (Jun Fig. 10: S1004) of traffic flow parameters (Jun ¶0129: information associated with traffic to be transmitted) and subscriber parameters for the traffic flows from the at least one network function (Jun ¶0129: ATSS AN), wherein the traffic flow parameters and subscriber parameters comprise Subscriber Identification (Jun ¶0129: target PDU session ID) determined via attributes seen (Jun ¶0129: associated with traffic to be transmitted) on a data plane of the computer network (Jun Fig. 3: 100, UE) and location of a subscriber (Jun ¶0129: user location information; Jun teaches an AMF requesting and receiving subscriber parameters, including the session ID and location information);
It would have been obvious for one skilled in the art, before the effective filing date of the claimed invention, to modify Qiao by way of Jun, to include an element that teaches an AMF requesting and receiving subscriber parameters, including the session ID and location information, as taught by Jun in Fig. 10 and ¶0129, to improve support for the ATSSS function to improve communication systems and reduce traffic usage in a switching cost associated with additional information requests.
Regarding Claim 2 and Claim 11
Qiao in view of Jun teaches the system and method disclosed in Claim 1. Qiao further teaches
wherein the SACP module is further configured to provide at least one traffic management action (Qiao ¶0244: SMF/UDM may correlate) based on the mapped subscriber to the traffic flow (Qiao ¶0244: SMF/UDM correlate map information from the AMF; Qiao teaches the SMF/UDM can correlate map information from the AMF).
Regarding Claim 3 and Claim 12
Qiao in view of Jun teaches the system and method disclosed in Claim 2. Qiao further teaches
wherein the traffic management action comprises instructions to another network node to implement the traffic action (Qiao Fig. 23: 2308, PolicyControl_Get; Qiao teaches a secondary message corresponding to implementing the previous action, Fig. 23, 2307).
Regarding Claim 4 and Claim 13

It would have been obvious for one skilled in the art, before the effective filing date of the claimed invention, to modify Qiao by way of Jun, to include an element that teaches the AMF receiving the user location information, as taught by Jun in Fig. 10 and ¶0129, to improve support for the ATSSS function to improve communication systems and reduce traffic usage in a switching cost associated with additional information requests.
Regarding Claim 5 and Claim 14
Qiao in view of Jun teaches the system and method disclosed in Claim 4. Jun further teaches
wherein the AMF event subscription and processing module is further configured to determine location updates for active subscribers (Jun ¶0130: When receiving S1004, AMF transmits a context update; Jun teaches the AMF updating the context message after receiving the user location information, S1004).
It would have been obvious for one skilled in the art, before the effective filing date of the claimed invention, to modify Qiao by way of Jun, to include an element that teaches the AMF updating the context message after receiving the user location information, S1004, as taught by Jun in ¶0130, to improve support for the ATSSS function to improve communication systems and reduce traffic usage in a switching cost associated with additional information requests.
