Regarding claims 5 and 12, Rajadurai et al. discloses: “prior to sending the first message, establishing using Transport Layer Security (TLS) encryption with the first network node and the second network node; and sending a secure transmission based on receiving the authentication challenge response” (FIG. 2: “3B, Secure session establishment” TLS/SSL using server certificate”). With respect to claims 6 and 13, Rajadurai et al. discloses: “the authentication challenge is processed using (Extended Authentication Protocol) EAP or Authentication and Key Agreement (AKA)” ([131]: “The UE 101 and the EDN 109 perform application layer specific authentication procedure (for example, EAP-AKA, TLS, HTTP-AKA, HTTPs)”). Claims 15 and 16 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by WIPO Publication No. WO2021115686 (Yang et al). Regarding claim 15, Yang et al. discloses: “a method (pg. 4, line 16: “Figure 1 shows an existing HTTP Digest AKA procedure”) for implemented by a network node (FIG. 1: UE/UICC); the method comprising: receiving a first message from a wireless transmit-receive unit (WTRU) (FIG. 8: 800-840; pg. 13, lines 11-15: “Figure 8 illustrates a communication device 800 (e.g., wireless device, UE) as implemented in accordance with one or more embodiments. As shown, the communication device 800 includes processing circuitry 810 and communication circuitry 820. The communication circuitry 820 (e.g., radio circuitry) is configured to transmit and/or receive information to and/or from one or more other nodes, e.g., via any communication technology. Such communication 15 may occur via one or more antennas 840”), wherein the first message indicates an authentication request (FIG. 1: “1) HTTP GET (Subscriber ID)”; pg. 4, lines 22-24: “UE sends an initial request (e.g., an HTTP GET message) which includes an identifier of the subscriber, e.g., a Mobile Station International Subscriber Directory Number (MSISDN) or an International Mobile Subscriber Identity (IMSI) to an authentication server”) sending an authentication challenge request to the WTRU (FIG. 1: “4) 401 Unauthorized Digest (RAND, AUTN)”; ); receiving an authentication challenge response from the WTRU (FIG. 1: “6) HTTP GET Digest (Hash derived from RES)”; pg. 5, line 4: “UE sends the generated Digest to the Auth Server in another request”); and sending a second message to the WTRU, wherein the second message indicates a response to the authentication request indicated by the first message” (FIG. 1: “8) “200 OK Digest (Hash derived from XRES”). With respect to claim 16, Yang et al. discloses: “the network node is an Authentication Server Function (AUSF)” (FIG. 1: “Auth Server”; pg. 4, lines 22-25: “UE sends an initial request (e.g., an HTTP GET message) which includes an identifier of the subscriber, e.g., a Mobile Station International Subscriber Directory Number (MSISDN) or an International Mobile Subscriber Identity (IMSI) to an authentication server (referred to as Auth Server in Figure 1)”). 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. Claims 2 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over Rajadurai et al. in view of US Patent Application Publication No. 20250184881 (Olvera-Hernandez et al). Claims 2 and 9 are dependent upon claims 1 and 8, respectively. As discussed above, Claims 1 and 8 are disclosed by Rajadurai et al. Thus, those limitations of claim 1 and Claim 8 that are recited in claims 2 and 9, respectively, are also disclosed by Rajadurai et al. However, Rajadurai et al. does not clearly disclose the remaining limitations of the claims. To that end with respect to claims 2 and 9, Olvera-Hernandez et al. discloses: “the first network node is a Network Repository Function (NRF)” ([0008]: “The WTRU may determine an endpoint address associated with the first network node. The WTRU may determine the endpoint address by sending a request for the endpoint address to a network repository function (NRF) and receiving a response indicating the endpoint address”). It is respectfully submitted that it would have been obvious to one of ordinary skill in the art at the time of the invention to combine Rajadurai et al. with Olvera-Hernandez et al. in order to provide an NRF as a first network node (e.g., see Olvera-Hernandez et al. @ [0008]). Claims 7 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Rajadurai et al. in view of US Patent Application Publication No. 20220240085 (Long). Claims 7 and 14 are dependent upon claims 1 and 8, respectively. As discussed above, Claims 1 and 8 are disclosed by Rajadurai et al. Thus, those limitations of claim 7 and 14 that are recited in claims 1 and 8, respectively, are also disclosed by Rajadurai et al. However, Rajadurai et al. does not clearly disclose the remaining limitations of the claims. To that end with respect to claims 7 and 14, Long discloses: “the identification of the WTRU is a Subscription Concealed Identifier (SUCI)” ([0016]: “ the encrypted identity of the subscriber of the UE may be a Subscription Concealed Identifier (SUCI)”). It is respectfully submitted that it would have been obvious to one of ordinary skill in the art at the time of the invention to combine Rajadurai et al. with the invention of Long in order to provide a WTRU/UE identity with a SUCI (e.g., see Long @ [0016]).
