DETAILED ACTION
Response to Amendment
In response to amendment filed on 7/14/2026, claims 1- 3, 6 and 12- 17 are amended and claims 4- 5 are cancelled and claims 18- 22 are added as new claims. Claims 1- 3, 6- 22 are pending for examinations.
Response to Arguments
Applicant’s arguments with respect to claim(s) filed in the remarks on 7/14/2026 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant has amended independent claim; hence examiner believes that the scope has been changed, therefore new reference Yao et al. (US Pub. No. 2020/0359244 A1) has been incorporated. Yao teaches about a control delay exception corresponding to the service flow corresponds to at least one of the following performance indicators of the service flow:
a quantity of packet data convergence protocol packets with an uplink air interface transmission delay greater than a first threshold,
a delay of processing a downlink packet by a user plane function network element,
a quantity of downlink packets on an N3 interface with a delay greater than a second threshold, or
a transmission delay of a downlink packet on an N3 interface (see Yao teaches in abstract regarding .. measurement and reporting of average UL and DL delays and delay distributions for an NG-RAN and UPF, as well as gNB-DU DL latency, for the N3 and N9 interfaces, internal UPF delay, and between the PSA UPF and NG-RAN and between the PSA UPF and UE are described…; further see [0051] The PSA UPF may calculate the UL/DL packet delay of the N3/N9 interface (the N9 interface is applicable when the intermediate UPF (I-UPF) exists). The UPF and RAN may report the QoS Monitoring result to the SMF based on a specific conditions, e.g., the first time, periodic, event triggered, or when thresholds for reporting towards SMF (via N4) are reached. The UPF performing the QoS monitoring can provide the corresponding (Network instance, Differentiated Services Code Point (DSCP)) along with the measured packet delay for the corresponding transport path to the SMF; further see [0182] Average Round-Trip N3 Delay for DL GTP Packets on PSA UPF)

As an example, if the user's QoE for the UE-ID and App-ID (example.com) is below a predefined target QoE (e.g., as per the SLA agreement), the consumer NF 900 may trigger a policy action aiming to improve the user's QoE, e.g., to a QoE level guaranteed as per the SLA agreement.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Please see PTO-892 form for considered prior arts for record.
Reference Sivaraj et al. (US Pat. No. 11044185 B2) teaches about reducing latency in a wireless communications network. Radio access network latency data corresponding to a measured latency impact criterion is obtained by a network device of a wireless network. Based on the radio access network latency data, latency guidance data usable by the radio network device to achieve a reduction in communication latency that is experienced by a user equipment is predicted, e.g., by a learned model. The latency guidance data can be used to facilitate a reduction in the communication latency that is experienced by a user equipment; see abstract.
Reference Khirallah et al. (US Pub. No. 2020/0280871 A1) teaches about the QoE measurement might typically involve, for example, QoE parameters directly affecting the user experience, which may be difficult or impossible to derive from QoS parameters. For example, in the case of video streaming services, measured QoE parameters might comprise initial delay (to start of the video) and number and/or duration of re-buffering events (due to buffer underflow) and video jitter. For web-browsing the delay until the web page is rendered in the user device is considered the main QoE metric. On the other hand, QoS parameters (e.g. packet loss), as in Table 1, would measure the network related performance; see [0060].
