Office Action

§102 §103 §112
DETAILED ACTION This Office Action is in response to the Application Ser. No. 19/173,927 filed on May 7, 2025. Claims 1-20 are pending and are examined. Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Priority Acknowledgment is made of applicant’s claim for domestic priority as a continuation of International Application Number PCT/CN2023/123317, filed on October 8, 2023. Acknowledgment is made of applicant's claim for foreign priority under 35 U.S.C. 119 (a)-(d) based on Chinese application Ser. No. 202211250071.8 filed on October 12, 2022. Receipt of the certified copy of the Chinese application on May 7, 2025, is hereby acknowledged. Claim Rejections - 35 USC § 112(b) The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claims 2, 9 and 14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 2 recites the limitation “wherein task identifiers of the plurality of data analytics tasks are the same” in lines 1-2. There is insufficient antecedent basis for the term “the plurality of data analytics tasks” in the claims. For examination purposes, the term “the plurality of data analytics tasks” is interpreted as “the one or more data analytics tasks”. Claim 9 recites the limitation “wherein the related information of the model comprises at least one of the following” in lines 1-2. There is insufficient antecedent basis for the term “the related information of the model” in the claims. For examination purposes, the term “the related information of the model” is interpreted as “related information of a model”. Insofar as it recites similar claim elements, Claim 14 is rejected for substantially the same reasons presented above with respect to Claim 2. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

Patentability shall not be negated by the manner in which the invention was made. Claims 2 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over 3GPP in view of Lee et al., Pub. No. US 2021/0144076 A1, hereby “Lee”. Regarding Claim 2, 3GPP discloses all of the limitations of Claim 1. However, while 3GPP discloses that the Nnwdaf_MLModelProvision_Subscribe message may be used to subscribe to a set of trained ML Models associated with a set of Analytics IDs, i.e., a plurality of data analytics tasks (3GPP § “6.2A.1 ML Model Subscribe/Unsubscribe” and “6.2A.2 Contents of ML Model Provisioning”), 3GPP does not explicitly disclose “wherein task identifiers of the plurality of data analytics tasks are the same.” In the same field of endeavor, Lee discloses “wherein task identifiers of the plurality of data analytics tasks are the same (Lee paragraphs 73-74: the same analytics ID may be associated with a plurality of analytics models, i.e., a plurality of data analytics tasks).” It would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the method of 3GPP to subscribe to a plurality of ML Models associated with the same Analytics ID as taught by Lee. One or ordinary skill in the art would have been motivated to combine subscribing to a plurality of ML Models associated with the same Analytics ID to obtain ML models that are optimized for different use cases of the analytics type (Lee paragraph 75). Insofar as it recites similar claim elements, Claim 14 is rejected for substantially the same reasons presented above with respect to Claim 2. Claims 6-8 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over 3GPP in view of Papageorgiou et al., Pub. No. US 2023/0060071 A1, hereby “Papageorgiou”. Regarding Claim 6, 3GPP discloses all of the limitations of Claim 1. However, while 3GPP discloses receiving an analytics subscription request, i.e., a task request, from a consumer NF (3GPP figs. 6.1.1.1-1 and 6.4.4-1 and § “6.1.1.1 Analytics subscribe/unsubscribe by NWDAF service consumer” and “6.4.4 Procedures to request Service Experience for an Application”: NWDAF receives Nnwdaf_AnalyticsSubscription_Subscribe message from consumer NF), 3GPP does not explicitly disclose “wherein before the sending, by a first communication device, a first request, the method further comprises at least one of the following: after receiving a task request, generating, by the first communication device, the first request for the task request (emphasis added); and after receiving a plurality of task requests within a preset time range, generating, by the first communication device, the first request for the plurality of task requests.” In the same field of endeavor, Papageorgiou discloses “wherein before the sending, by a first communication device, a first request, the method further comprises at least one of the following: after receiving a task request, generating, by the first communication device, the first request for the task request (Papageorgiou figs. 3 and 4 and paragraphs 105 and 123-125: the NWDAF service consumer, e.g., the NWDAF containing AnLF, sends the model provisioning request, e.g., a Nnwdaf_MLModelProvision_Subscribe message, in response to receiving a request for analytics data from an analytics consumer, e.g., an Nnwdaf_AnalyticsSubscription_Subscribe message); and after receiving a plurality of task requests within a preset time range, generating, by the first communication device, the first request for the plurality of task requests.” It would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the method of 3GPP to transmit, by the NWDAF containing AnLF, the Nnwdaf_MLModelProvision_Subscribe message in response to receiving the Nnwdaf_AnalyticsSubscription_Subscribe message from the NF consumer as taught by Papageorgiou. One of ordinary skill in the art would have been motivated to combine transmitting the Nnwdaf_MLModelProvision_Subscribe message in response to receiving the Nnwdaf_AnalyticsSubscription_Subscribe message from the NF consumer to obtain ML Model(s) that can be used to support the analytics task requested by the NF consumer (Papageorgiou paragraph 125). Regarding Claim 7, the combination of 3GPP and Papageorgiou discloses all of the limitations of Claim 6. Additionally, Papageorgiou discloses “wherein task identifiers of a plurality of data analytics tasks corresponding to the plurality of task requests are the same (Papageorgiou paragraphs 119 and 122-124: the same analytics ID may be associated with different ML Models for different use cases, i.e., a plurality of data analytics tasks). It would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the method of 3GPP to transmit, by the NWDAF containing AnLF, the Nnwdaf_MLModelProvision_Subscribe message in response to receiving the Nnwdaf_AnalyticsSubscription_Subscribe message from the NF consumer as taught by Papageorgiou for the reasons set forth in the rejection of Claim 6. Regarding Claim 8, the combination of 3GPP and Papageorgiou discloses all of the limitations of Claim 6. Additionally, 3GPP discloses “wherein the task request comprises at least one of the following: task identification information (3GPP § “6.1.3 Contents of Analytics Exposure”: Nnwdaf_AnalyticsSubscription_Subscribe message comprises a list of Analytics ID(s), i.e., task identification information); condition restriction information of the task; and analytics object information of the task (3GPP § “6.1.3 Contents of Analytics Exposure”: Nnwdaf_AnalyticsSubscription_Subscribe message comprises Target of Analytics Reporting indicating the object(s) for which Analytics information is requested, e.g., specific UEs, group of UEs, or all UEs).” Regarding Claim 20, 3GPP discloses “send a first request, wherein the first request is used to request a plurality of models for one or more data analytics tasks (3GPP fig. 6.2A.1-1, § “6.2A.1 ML Model Subscribe/Unsubscribe” and “6.2A.2 Contents of ML Model Provisioning”: an NWDAF service consumer, e.g., an NWDAF containing AnLF, sends a request, i.e., Nnwdaf_MLModelProvision_Subscribe message, to subscribe to a set of trained ML Models associated with a set of Analytics IDs, i.e., one or more data analytics tasks – while not explicitly stated, implementation of the NWDAF functionality by one or more hardware devices is inferred); and receive a first response, wherein the first response comprises related information of a plurality of models meeting the first request (3GPP fig. 6.2A.1-1, § “6.2A.1 ML Model Subscribe/Unsubscribe” and “6.2A.2 Contents of ML Model Provisioning”: the NWDAF service consumer, e.g., the NWDAF containing AnLF, receives a response, i.e., a Nnwdaf_MLModelProvision_Notify message, comprising trained ML Model Information for the set of trained ML Models – while not explicitly stated, implementation of the NWDAF functionality by one or more hardware devices is inferred). However, while implementation of the NWDAF functionality disclosed in 3GPP by one or more hardware devices is inferred (3GPP figs. 6.1.1.1-1 and 6.4.4-1 and § “5.1 General”, “6.1.1.1 Analytics subscribe/unsubscribe by NWDAF service consumer” and “6.4.4 Procedures to request Service Experience for an Application”), 3GPP does not explicitly disclose “A model request apparatus, comprising: at least one hardware processor and a memory, wherein the memory stores a program or instructions capable of running on the at least one hardware processor, and when the program or instructions are executed by the at least one hardware processor...” In the same field of endeavor, Papageorgiou discloses “A model request apparatus (Papageorgiou figs. 3, 4 and 6 and paragraphs 102, 122 and 163-164: an apparatus 600 implementing an NWDAF service consumer, e.g., an NWDAF AnLF), comprising: at least one hardware processor and a memory, wherein the memory stores a program or instructions capable of running on the at least one hardware processor, and when the program or instructions are executed by the at least one hardware processor... (Papageorgiou fig. 6 and paragraphs 154-157 and 163-164: at least one processor 610 executing program instructions stored in at least one memory 620)”. It would have been obvious to one of ordinary skill in the art at the time of the effective filing to implement the NWDAF functionality using an apparatus comprising a processor executing program instructions stored in memory as taught by Papageorgiou because doing so constitutes applying a known technique (implementing NWDAF functionality using an apparatus comprising a processor and memory) to known devices and/or methods (an NWDAF service consumer) ready for improvement to yield predictable and desirable results (implementation of NWDAF service consumer using a generic computing device). See KSR International Co. v. Teleflex Inc., 82 USPQ2d 1385 (U.S. 2007). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Fu et al., Pub. No. US 2025/0111223 A1, discloses a method for requesting, from a consumer NWDAF, a trained machine learning model from a producer NWDAF, wherein the consumer NWDAF may include a reliability requirement in the model provisioning request; and Shariat et al., Pub. No. US 2024/0244466 A1, discloses methods for providing information based on UE locations in 3GPP 5G network using NWDAF data analytics wherein a certain analytics ID identifies a distinct analytics type for a family of use cases.
