Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 01/26/2026 has been entered. Response to Arguments Applicant’s arguments, see REMARKS, filed 01/26/2026, with respect to 102 rejections of claims 1, 4, 9, 10, 13, 15, and 18 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Huang-Fu et al.. 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, 4, 6-7, 9-11, 13, 15-16, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Huang-Fu et al. (US 20200351755 A1) in view of Nokia (5GMM cause value for CAG, 3GPP TSG-CT WG1 Meeting #117, C1-193510, Reno (NV), USA, 13-17 May 2019. Regarding claim 1, Huang-Fu et al. teach A method for managing a closed access group (CAG) feature by a user equipment (UE), the method comprising: transmitting, to an access and mobility management function (AMF), a registration request message (Huang-Fu [0033] The UE 124 can send a registration request message to the AMF 130 to initiate the registration procedure 500, at step S502) including information indicating that the UE does not support the CAG feature (Huang-Fu [0031] if the CAG only bit 306 is set to “0,” “indication that the UE is only allowed to access 5GS via CAG cells” is not set), wherein the information indicating that the UE does not support the CAG feature is a one-bit information (Huang-Fu [0031] a CAG only bit 306) provided in a 5GMM capability information element of the registration request message (Huang-Fu [0038] the UE 124 can set the CAG bit to “CAG Supported” in a 5GMM capability IE of the registration request message); and receiving, from the AMF, a registration reject message including non-access-stratum (NAS) cause (Huang-Fu [0033] At step S504, if the registration request message is rejected by the network, the AMF 130 shall send a registration reject message to the UE 124 including an appropriate 5GMM cause value, such as a value cause #76 (Not authorized for this CAG or authorized for CAG cells only))in response to the registration request message in case that the UE does not support the CAG feature and the UE is allowed to access a 5G system (5GS) via a CAG cell only (Huang-Fu [0033] an appropriate 5GMM cause value, such as a value cause #76 (Not authorized for this CAG)). Huang-Fu et al. do not teach wherein the NAS cause is one of NAS cause #7, NAS cause #11, and NAS cause #27. However, Nokia teaches wherein the NAS cause is one of NAS cause #7 (Nokia 5.5.1.2.5 #7 (5GS services not allowed), NAS cause #11, and NAS cause #27. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the examined application to have modified Huang-Fu et al. by incorporating Nokia cause # 7 when the UE request registering to a 5G system to arrive at the invention The motivation of doing so would have included UE registration attempts to 5G system. Regarding claim 2, the combination of Huang-Fu et al. and Nokia teaches The method of claim 1, wherein the UE camps a non-CAG cell of a network (Nokia Summary of change: If the UE is accessing the network via a non-CAG cell) which supports the CAG feature .(Huang-Fu [0032] the AMF 130) can provision the CAG information list to the UE 124) and the AMF supports the CAG feature (Huang-Fu [0032] the AMF 130) can provision the CAG information list to the UE 124)).
