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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 07/02/2026 has been entered.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1-2, 6 are rejected under 35 U.S.C. 103 as being unpatentable over Rajavelsamy Rajadurai et al (US 20220377548 A1) in view of Stefano Faccin et al (US 20230102300 A1) & Seongkyu Song et al (US 20220416880 A1).
Claims 1-6 of the instant application are directed to a wireless communication network comprising network node that receives a registration request from a terminal; transmits information indicating withholding of a registration acceptance to the terminal; performs verification related to a requirement of the terminal to be connected to a network. In a case where the verification is successful, the registration of the terminal is accepted, and, in a case where the verification fails, the registration of the terminal is not accepted, the system shown in FIG. 6.

The Qiao reference, for its part, cures the deficiency of Rajadurai. The Faccin reference is concerned with a mechanism for unmanned vehicle authorization for operation over cellular networks, whereby a UE 108 sends a registration request 333 message to a AMF 322; the AMF 322 sends Registration Accept message 345. The registration accept message may include an indication that a USAA procedure is pending or is to be performed before the UE may gain access to aerial services. The process flow is depicted in FIG. 3, below.

For Claim 1, Rajadurai discloses a network node comprising: a receiver configured to receive a registration request from a terminal (Rajadurai teaches, in Fig. 8, step 801, that UE 108 sends a registration request 801 message to a AMF 502); withholding of a registration acceptance to the terminal (Rajadurai teaches, in Fig. 8, step 802, that the AMF 502 sends the SUCI to the AUSF 504 over the Nausf_UEAuthentication_Authenticate request message to the AUSF); and a processor configured to perform verification related to a requirement of the terminal to be connected to a network (Rajadurai teaches, in Fig. 8, step 804, that the UDM 506 verifies if the UE 106 has the permissions to access the requested CAG cell/NPN 104), wherein in a case where the verification by the control unit is successful, the registration of the terminal is accepted (Rajadurai teaches, in ¶ 0058, that If the UE 106 has the permissions to access the selected network 104, the PLMN 102 may perform a primary authentication procedure of the UE 106 and allow the UE 106 to access the selected network 104 for the communication services, if the primary authentication procedure of the UE 106 is successful), and, in a case where the verification fails, the registration of the terminal is not accepted (Rajadurai further teaches, in ¶ 0206, that At step 808b, the AMF 502 sends the reject message to the UE 106 in the unprotected reject mode).
Rajadurai fails to expressly teach transmitting the information indicating the withholding of a registration acceptance, and wherein the network node is included in a satellite.
However, Faccin, in analogous art, discloses transmitting the information indicating the withholding of a registration acceptance, and wherein the network node is included in a satellite (Faccin teaches, in ¶ 0146, that the AMF 322 sends Registration Accept message 345. The registration accept message may include an indication that a USAA procedure is pending or is to be performed before the UE may gain access to aerial services).
Faccin teaches, in ¶ 0141, that At block 331, a UE that is coupled with UAV 320 may perform a procedure for obtaining a UUID and credentials used to protect communications between UAV 320 and UFMS 324.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the communication system taught in Rajadurai with the USAA operations as taught in Faccin. The motivation is to allow a UE to register with and establish a data session with a wireless network [Faccin: ¶ 0005]
Rajadurai & Faccin fail to expressly teach that the satellite is in an orbit at least 150 kilometers above a surface of the Earth.
However, Song, in analogous art, discloses the satellite is in an orbit at least 150 kilometers above a surface of the Earth (Song teaches, in ¶ 0118, that In operation 1511, an LEO-AN transmits, to the UE which transmits the registration request, a message informing registration acceptance. In operation 1512, the UE which receives the message informing the registration acceptance transmits, to the LEO-AN, a message informing registration completion as an acknowledgment response).
Song further teaches, in ¶ 0069, that the plurality of satellites 230a, 230b, . . . , 230f may include a base station function for a wireless access of a UE. The satellites 230a, 230c, and 230e may move along a first orbit ORBIT1 or may be fixed to an orbit which is a geostationary orbit.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the communication system taught in Rajadurai with the LEO-AN taught in Song. The motivation is for reducing a delay in a wireless communication system using a satellite [Song: ¶ 0010]
For Claim 3, Rajadurai discloses a network node, wherein the requirement is a requirement related to a geographical location of the terminal (Rajadurai teaches, in ¶ 0050, that the PLMN 102 located in the area 1 acts as the HPLMN 102 for the UE 106. The HPLMN 102 manages the UE profile and provides the communication services to the UE 106, when the UE 106 is located in the area 1. When the UE 106 roams to an area 2, the HPLMN 102 may no longer provide the communication services to the UE 106)
For Claim 6, please refer to the rejection of claim 1, above.
Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Rajavelsamy Rajadurai et al (US 20220377548 A1) in view of Stefano Faccin et al (US 20230102300 A1) & Seongkyu Song et al (US 20220416880 A1) as applied to claim 1 above, and further in view of Vijay Venkataraman et al (US 20220312182 A1).
For Claim 2, Rajadurai, Faccin and Song disclose all of the claimed subject matter with the exception that the information indicating the withholding indicates that a target of the verification is a geographical location of the terminal and that, in addition to a normal call, an emergency call is not permitted during the withholding.
However, Venkataraman, in analogous art, discloses that the information indicating the withholding indicates that a target of the verification is a geographical location of the terminal (Venkataraman teaches, in ¶ 0023, lines 7-11, that network configurations in certain locations (e.g., PLMN A having 5G network setup but having emergency calls supported only in 2G and/or 3G) can indicate that IMS emergency calls are not supported) and that, in addition to a normal call, an emergency call is not permitted during the withholding (Venkataraman teaches, in ¶ 0073, lines 14-19, that In certain such embodiments, the SIB comprises a first SIB (SIB1) including a first information element (IE) configured to indicate whether a roaming emergency policy is allowed or disallowed, or a second SIB (SIB2) including a second IE to indicate a roaming emergency barring policy).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the communication system taught in Rajadurai and Faccin with the roaming emergency policy taught in Venkataraman. The motivation is to inform the UE whether or not the use of emergency services is supported.
Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Rajavelsamy Rajadurai et al (US 20220377548 A1) in view of Stefano Faccin et al (US 20230102300 A1) & Seongkyu Song et al (US 20220416880 A1) as applied to claim 3 above, and further in view of Kai Du et al (WO 2022178938 A1).
For Claim 4, Rajadurai, Faccin and Song disclose all of the claimed subject matter with the exception that a terrestrial coverage region corresponding to the radio network node overlaps, geographically, with the non-terrestrial geographic zone.
However, Du, in analogous art, discloses wherein the control unit determines that the verification is successful in a case where the geographical location of the terminal corresponds to the network (Du teaches, in FIG. 4, S404, when the current geographic location is within the valid geographic location range, accept and process the registration request), and determines that the verification fails in a case where the geographical location of the terminal does not correspond to the network (Du teaches, in FIG. 4, S405, when the current geographic location of the terminal is not within the valid geographic location range, reject and discard the registration request).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the communication system taught in Rajadurai and Faccin with acquiring the geographic location of the terminal as taught in Du. The motivation is to use geographic information in determining a target cell from among the valid cells.
Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Rajavelsamy Rajadurai et al (US 20220377548 A1) in view of Stefano Faccin et al (US 20230102300 A1), Seongkyu Song et al (US 20220416880 A1) & Kai Du et al (WO 2022178938 A1) as applied to claim 4 above, and further in view of Kundan Tiwari et al (US 20240187968 A1).
For Claim 5, Rajadurai, Faccin, Song and Du disclose all of the claimed subject matter with the exception that a terrestrial coverage region corresponding to the radio network node overlaps, geographically, with the non-terrestrial geographic zone.
However, Tiwari, in analogous art, discloses wherein the control unit determines that the verification is successful in a case where the geographical location of the terminal corresponds to the network (Tiwari teaches, in in ¶ 0612, that For NR satellite access, if the AMF can determine based on the Selected PLMN ID and ULI (including Cell ID) received from the gNB that the UE is attempting to register to a PLMN that is not allowed to operate at the present UE location, then the AMF should reject the Registration Request indicating a suitable Cause value and, if known in AMF, the country of the UE location. … and be prepared to deregister the UE if the information received from LMF proves that the UE is registered to a PLMN that is not allowed to operate in the UE location).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the communication system taught in Rajadurai, Faccin and Du with deregistering the terminal as taught in Tiwari. The motivation is to prevent the UE from accessing a PLMN that it is not is not allowed to operate in.
Response to Arguments
Applicant’s arguments with respect to claim(s) 1-6 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.
