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 remarks dated 1/22/2026 have been considered and are moot in view of arguments presented. As to applicant remarks to Claim 1, “Thus, Han's "ID of a slice" does NOT explicitly teach Applicant's "slice information" which is created (when the control device 100 joins the 5G network), for connecting to the same number of user plane functions (UPFs) as the total number of emergency stop groups.” Claim 1 limitation is about slice information which can be interpreted many ways and in Han it has been interpreted as Slice ID. Claim 1 limitation does not mention applicant argument of this “slice information” being “created” is described by Han in [227]- Therefore, in this application, a virtual extensible local area network (virtual extensible local area network, VXLAN) tunneling technology is used to allocate a VNI to a tunnel between a UPF network element and a network device (for example, a switch) connected to a LAN in the target group, to identify the tunnel. 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. Claim(s) 1,2,5,6,10 are rejected under 35 U.S.C. 103 as being unpatentable over Han et al.( US20220182804A1) in view of Ueda et al. (US20170075336A1) Regarding Claim 1,Han teaches, A communication control system including a plurality of control devices that communicate via a fifth-generation mobile communication system (5G) network and a plurality of controlled devices respectively controlled by the plurality of control devices, Fig 2B [13]- a process of providing the service of the 5GVN(=fifth-generation mobile communication system (5G) network) for the terminal device in the target group is provided: The SMF network element determines, based on the PDU session establishment request initiated by the terminal device( =control devices, fig 2b terminal devices 1/2/3 and UPF, the second UPF network element at which the terminal device is anchored and delivers the third routing information to the second UPF network element.
