Considering objective evidence present in the application indicating obviousness or nonobviousness. 07-20-02-aia AIA 7. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. 07-21-aia AIA 8.

Wang does not explicitly teach the first indication information indicates to determine the first key by using a master key. Teyeb teaches using a master key to determine the first key ( ¶ [0058], ¶ [0059] ). Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to indicate, in the first indication information, to determine the first key by using a master key in the system of Wang to further improve industrial applicability. Regarding claims 3 and 16 , Wang teaches the communication method according claim 1.

Similar mapping can also be performed when changing from LTE PDCP to NR PDCP (mapping from LTE algorithm to NR algorithm).

Similar mapping can also be performed when changing from LTE PDCP to NR PDCP (mapping from LTE algorithm to NR algorithm).

Wang does not explicitly teach wherein the method further comprises: when the terminal device supports the user plane integrity protection, determining, by the access network device of the first network standard, the integrity protection algorithm identifier of the second network standard based on the security capability of the first network standard. Li teaches the access network device determines a user plane protection algorithm identifier based on the terminal device capability (i.e., user plane protection algorithm supported by the terminal) ( ¶ [0220]-¶ [0223] ). Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to determine, by the access network device of the first network standard, the integrity protection algorithm identifier of the second network standard based on the security capability of the first network standard when the terminal device supports the user plane integrity protection in the system of Wang in view of Teyeb to select/utilize a security policy/algorithm that the terminal and the network is able to support. .

Wang does not explicitly teach wherein the method further comprises: when the terminal device supports the user plane integrity protection, determining, by the access network device of the first network standard, the integrity protection algorithm identifier of the second network standard based on the security capability of the first network standard. Suh teaches the access network device determines a user plane protection algorithm identifier based on whether the terminal device has a capability to support user pane related security protection ( ¶ [0010], ¶ [0056], a parameter to be sent from the UE 101 to the network. Information delivered by the additional security protection parameter indicates whether the UE has a capability to support user plane related security protection.

Wang does not explicitly teach wherein the user plane integrity protection indication information, the integrity protection algorithm identifier of the second network standard, and the first indication information are encapsulated in a radio bearer configuration (Radiobearerconfig) information element of the first message. Rugeland teaches SecurityConfig in the RadioBearerConfig information elements (lEs), allows configuration of both ciphering and integrity protection algorithms. The RadioBearerConfig IE defined in TS 38.331 is shown in Table 1 ( page 3 lines 25-28 ). Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to encapsulate the user plane integrity protection indication information, the integrity protection algorithm identifier of the second network standard, and the first indication information in a radio bearer configuration (Radiobearerconfig) information element of the first message in the system of Wang in view of Teyeb to comply with 3GPP requirements . 07-21-aia AIA 12.
