Office Action

§103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments 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, specifically Dao et al. (US 20200145876 A1). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 2. Claims 1, 3-11 and 14, and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Thiebaut et al. (US 20220200813 A1) in view of Rossbach et al. (US 20230269620 A1) and Dao et al. (US 20200145876 A1). Claim 1 Thiebaut teaches a session management function (SMF) of a network architecture, comprising: at least one memory; (FIG. 11, ¶0239, Processor 111/115) and at least one processor coupled with the at least one memory (FIG. 11, ¶0240, Memory 112/116) and configured to cause the SMF to: construct traffic handling information (FIG. 5, S53, ¶0097, generating a first rule related to traffic offloading, i.e. traffic handling information) based on traffic configuration information obtained from a network entity; (FIG. 5, step S51 and S52, ¶0097, constructing based on the obtained information and pre-rule, i.e., traffic configuration information obtained from a session management entity, i.e. a network entity) and transmit, to a user plane function (UPF), the constructed traffic handling information. (FIG. 5, step S55, ¶0097, transmitting the first rule to the user plan function) However, Thiebaut does not explicitly teach extended reality (XR) traffic; and wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Rossbach teaches extended reality (XR) traffic configuration information. (¶0136, XR traffic pattern characteristics, wherein pattern characteristics comprise configuration information) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut to incorporate the extended reality (XR) techniques for applications and data taught in Rossbach in order to more effectively utilize network resources for extended reality applications and programs. However, Thiebaut in view of Rossbach does not explicitly teach wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Dao teaches data traffic handling information instructs (¶0108, wherein a parameter instructs, wherein the parameter comprises the data traffic handling information) the UPF (FIG. 3, UPF 304, ¶0065) to extract application-aware parameters from an N6 interface (¶0108, the adding of the timestamp to the packet header or the tunnel header of the packet, wherein the timestamp is from the N6 interface, i.e. wherein it is extracted from the N6 interface) and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) (FIG. 3, ¶0065, using General Packet Radio Service (GPRS) Tunneling Protocol for user plane (GTP-U) tunnels 328) header of an N3 interface or an N9 interface. (¶0108, adding, i.e. pasting, a timestamp to packet header of the N3 or N9 header) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut in view of Rossbach to handle packets for URLLC applications not subject to one or more limitations known in the prior art. (Dao, ¶0007) Claim 3 Thiebaut in view of Rossbach, and Dao teaches Claim 1, and further teaches wherein the XR traffic configuration information is an XR traffic indication. (Rossbach, ¶0136, wherein XR traffic pattern characteristics comprise XR traffic indications) Claim 4 Thiebaut in view of Rossbach, and Dao teaches Claim 1, and further teaches wherein the XR traffic configuration information further includes possible values of packet characteristic information. (Rossbach, ¶0136, wherein XR traffic includes pattern characteristics, i.e. packet characteristic information) Claim 5 Thiebaut in view of Rossbach, and Dao teaches Claim 1, and further teaches wherein the at least one processor is further configured to cause the SMF to obtain the XR traffic configuration information as part of a policy and charging control (PCC) rule (Thiebaut, ¶0097, wherein the traffic configuration information is part of a pre-rule, i.e. PCC rule) from a policy control function (PCF). (Rossbach, ¶0125, from a policy control function) Claim 6 Thiebaut in view of Rossbach, and Dao teaches Claim 1, and further teaches wherein the at least one processor is further configured to cause the SMF to obtain the XR traffic configuration information as part of packet flow description (PFD) management (Thiebaut, ¶0125, wherein the traffic configuration information is part of flow management, i.e. a rule for managing flow) from a PFD function in a network exposure function (NEF). (Rossbach, ¶0125, from a network exposure function) Claim 7 Thiebaut in view of Rossbach, and Dao teaches Claim 1, and further teaches wherein the XR traffic handling information comprises a mapping relationship between a quality of service (QoS) flow identifier (QFI) and packet characteristic information. (Rossbach, ¶0128, mapping the QoS/QFI to the XR data traffic, i.e. packet characteristic info) Claim 8 Thiebaut in view of Rossbach, and Dao teaches Claim 1, and further teaches wherein the at least one processor is further configured to cause the SMF to transmit correlation of quality of service (QoS) flow identifiers (QFIs) to a radio access network (RAN) node. (Rossbach, ¶0124, transmitting to a radio access network interface) Claim 9 Thiebaut in view of Rossbach, and Dao teaches Claim 7, and further teaches wherein the at least one processor is further configured to cause the SMF to transmit, to a radio access network (RAN) node, the mapping relationship between the QFI and the packet characteristic information. (Rossbach, ¶0124, transmitting the traffic configuration information, i.e. the mapping relationship, to a radio access network interface) Claim 10 Thiebaut teaches a user plane function (UPF) of a network architecture, comprising: at least one memory; (FIG. 11, ¶0238, a network node having processor 111/115) and at least one processor coupled with the at least one memory (FIG. 11, ¶0238, a network node having memory 112/116) and configured to cause the UPF to: receive, from a session management function (SMF), traffic handling information; (FIG. 5, step S55, ¶0097, receiving from a SMF the first rule to the user plan function by the UPF) and process packets carrying traffic in response to the received traffic handling information. (¶0097, wherein the UPF processes received traffic according to the rule) However, Thiebaut does not explicitly teach extended reality (XR) traffic, and wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the application-aware parameters into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Rossbach teaches extended reality (XR) traffic configuration information. (¶0136, XR traffic pattern characteristics, wherein pattern characteristics comprise configuration information) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut to incorporate the extended reality (XR) techniques for applications and data taught in Rossbach in order to more effectively utilize network resources for extended reality applications and programs. However, Thiebaut in view of Rossbach does not explicitly teach wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Dao teaches data traffic handling information instructs (¶0108, wherein a parameter instructs, wherein the parameter comprises the data traffic handling information) the UPF (FIG. 3, UPF 304, ¶0065) to extract application-aware parameters from an N6 interface (¶0108, the adding of the timestamp to the packet header or the tunnel header of the packet, wherein the timestamp is from the N6 interface, i.e. wherein it is extracted from the N6 interface) and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) (FIG. 3, ¶0065, using General Packet Radio Service (GPRS) Tunneling Protocol for user plane (GTP-U) tunnels 328) header of an N3 interface or an N9 interface. (¶0108, adding, i.e. pasting, a timestamp to packet header of the N3 or N9 header) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut in view of Rossbach to handle packets for URLLC applications not subject to one or more limitations known in the prior art. (Dao, ¶0007) Claim 11 is taught by Thiebaut in view of Rossbach, and Dao as described for Claim 5. Claim 14 Thiebaut teaches a method performed by a session management function (SMF) of a network architecture, the method comprising: constructing traffic handling information (FIG. 5, S53, ¶0097, generating a first rule related to traffic offloading, i.e. traffic handling information) based on traffic configuration information obtained from a network entity; (FIG. 5, step S51 and S52, ¶0097, constructing based on the obtained information and pre-rule, i.e., traffic configuration information obtained from a session management entity, i.e. a network entity) and transmitting, to a user plane function (UPF), the constructed traffic handling information. (FIG. 5, step S55, ¶0097, transmitting the first rule to the user plan function) However, Thiebaut does not explicitly teach extended reality (XR) traffic, and wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the application-aware parameters into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Rossbach teaches extended reality (XR) traffic configuration information. (¶0136, XR traffic pattern characteristics, wherein pattern characteristics comprise configuration information) However, Thiebaut in view of Rossbach does not explicitly teach wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Dao teaches data traffic handling information instructs (¶0108, wherein a parameter instructs, wherein the parameter comprises the data traffic handling information) the UPF (FIG. 3, UPF 304, ¶0065) to extract application-aware parameters from an N6 interface (¶0108, the adding of the timestamp to the packet header or the tunnel header of the packet, wherein the timestamp is from the N6 interface, i.e. wherein it is extracted from the N6 interface) and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) (FIG. 3, ¶0065, using General Packet Radio Service (GPRS) Tunneling Protocol for user plane (GTP-U) tunnels 328) header of an N3 interface or an N9 interface. (¶0108, adding, i.e. pasting, a timestamp to packet header of the N3 or N9 header) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut in view of Rossbach to handle packets for URLLC applications not subject to one or more limitations known in the prior art. (Dao, ¶0007) Claim 16 Thiebaut in view of Rossbach, and Dao teaches Claim 14, and further teaches wherein the XR traffic configuration information is an XR traffic indication. (Rossbach, ¶0136, wherein XR traffic pattern characteristics comprise XR traffic indications) Claim 17 Thiebaut in view of Rossbach, and Dao teaches Claim 14, and further teaches wherein the XR traffic configuration information further includes possible values of packet characteristic information. (Rossbach, ¶0136, wherein XR traffic includes pattern characteristics, i.e. packet characteristic information) Claim 18 Thiebaut in view of Rossbach, and Dao teaches Claim 14, and further teaches wherein the at least one processor is further configured to cause the SMF to obtain the XR traffic configuration information as part of a policy and charging control (PCC) rule (Thiebaut, ¶0097, wherein the traffic configuration information is part of a pre-rule, i.e. PCC rule) from a policy control function (PCF). (Rossbach, ¶0125, from a policy control function) Claim 19 Thiebaut in view of Rossbach, and Dao teaches Claim 14, and further teaches wherein the at least one processor is further configured to cause the SMF to obtain the XR traffic configuration information as part of packet flow description (PFD) management (Thiebaut, ¶0125, wherein the traffic configuration information is part of flow management, i.e. a rule for managing flow) from a PFD function in a network exposure function (NEF). (Rossbach, ¶0125, from a network exposure function) Claim 20 Thiebaut teaches a processor for wireless communication, comprising: at least one controller (FIG. 11, ¶0239, Processor 111/115, Examiner interprets Claim 20 as the processor as the SMF and the controller as its processor) coupled with at least one memory (FIG. 11, ¶0240, Memory 112/116) and configured to cause the processor to: construct traffic handling information (FIG. 5, S53, ¶0097, generating a first rule related to traffic offloading, i.e. traffic handling information) based on traffic configuration information obtained from a network entity; (FIG. 5, step S51 and S52, ¶0097, constructing based on the obtained information and pre-rule, i.e., traffic configuration information obtained from a session management entity, i.e. a network entity) and transmit, to a user plane function (UPF), the constructed traffic handling information. (FIG. 5, step S55, ¶0097, transmitting the first rule to the user plan function) However, Thiebaut does not explicitly teach extended reality (XR) traffic, and wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the application-aware parameters into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Rossbach teaches extended reality (XR) traffic configuration information. (¶0136, XR traffic pattern characteristics, wherein pattern characteristics comprise configuration information) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut to incorporate the extended reality (XR) techniques for applications and data taught in Rossbach in order to more effectively utilize network resources for extended reality applications and programs. However, Thiebaut in view of Rossbach does not explicitly teach wherein the XR data traffic handling information instructs the UPF to extract application-aware parameters from an N6 interface and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) header of an N3 interface or an N9 interface. From a related technology, Dao teaches data traffic handling information instructs (¶0108, wherein a parameter instructs, wherein the parameter comprises the data traffic handling information) the UPF (FIG. 3, UPF 304, ¶0065) to extract application-aware parameters from an N6 interface (¶0108, the adding of the timestamp to the packet header or the tunnel header of the packet, wherein the timestamp is from the N6 interface, i.e. wherein it is extracted from the N6 interface) and paste the extracted application-aware parameters from the N6 interface into an extended general packet radio service (GPRS) tunnelling protocol user plane (GTP-U) (FIG. 3, ¶0065, using General Packet Radio Service (GPRS) Tunneling Protocol for user plane (GTP-U) tunnels 328) header of an N3 interface or an N9 interface. (¶0108, adding, i.e. pasting, a timestamp to packet header of the N3 or N9 header) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut in view of Rossbach to handle packets for URLLC applications not subject to one or more limitations known in the prior art. (Dao, ¶0007) Claim 21 is taught by Thiebaut in view of Rossbach, and Dao as described for Claim 7. Claim 22 is taught by Thiebaut in view of Rossbach, and Dao as described for Claim 15. Claim 23 is taught by Thiebaut in view of Rossbach, and Dao as described for Claim 4. 3. Claims 12 is rejected under 35 U.S.C. 103 as being unpatentable over Thiebaut et al. (US 20220200813 A1) in view of Rossbach et al. (US 20230269620 A1), Dao et al. (US 20200145876 A1) and in further view of Yang et al. (US 20240414586 A1). Claim 12 Thiebaut in view of Rossbach, and Dao teaches Claim 11, but does not explicitly teach wherein to process the packets carrying the XR traffic, the at least one processor is configured to cause the UPF to mark each of the packets carrying the XR traffic with the QFI based on the packet characteristic information received from a user plane. Yang teaches mark each of the packets carrying the XR traffic with the QFI based on the packet characteristic information. (¶0056, marking each XR packet with the QFI) It would be obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Thiebaut in view of Rossbach, and Dao to incorporate the teachings of Yang to distinguish between XR traffic using the QFI in order to more effectively utilize network resources for extended reality applications and traffic.
