DETAILED ACTION
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 .
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 08/19/2026 has been entered.
Response to Remarks
This Office Action is considered to be fully responsive to the communications filed on 07/22/2026. Claims 1-3, 6, 10-12, 15, and 19-21 are currently pending in this application.
Response to Arguments
Applicant’s arguments, see Remarks pages 6-8, filed 07/22/2026, with respect to the rejections of claims 1-3, 6, 10-12, 15, and 19-21 under 35 U.S.C 102 and 35 U.S.C. 103 have been fully considered but are not persuasive. Applicant has amended independent claim 1 to specify that the message is “at least one of a registration message or a configuration update message”, and that the parameter information is “carried in the at least one of the registration message or the configuration update message”, where independent claims 10 and 19 are also amended in a similar way such that they contain analogous subject matter. Applicant argues on pages 6-8 of Remarks that Chun does not teach these features of the claims, stating that “Chun does not disclose that the various configurations contained in SIB2 (mapped to the claimed “configuration update message”) carry the barring parameters contained in SIB2”. This argument is however moot, as the claim language does not require this to be true. The claim language, as it is written, requires that there is a configuration update message (the SIB2 is the configuration update message) which “carries parameter information” (the SIB2 includes barring parameters, which is the parameter information). Thus, Chun teaches this claim limitation as it is written. Applicant then goes on to argue that “Chun does not disclose that its SIB2 contains a registration message carrying parameter information or a configuration update message carrying parameter information based on which a duration of a first timer is determined”. Again Examiner disagrees with this opinion, as Chun does teach this feature, and a claim mapping is provided below. Chun clearly shows that the SIB2 includes configurations, which means that the SIB2 is a “configuration update message” by the plain meaning of the words. Given that the SIB2 (configuration update message) contains the barring parameters (parameter information) which are used to control the timer (parameter information used for the timer), Chun does indeed teach this feature. Applicant then argues on page 7 of Remarks that “as is well understood by those skilled in the art, a registration message or a configuration update message is a Non-Access Stratum (NAS) message exchanged between a core network and a User Equipment (UE)”. Examiner however disagrees with this opinion, as the claimed terms “registration message” and “configuration update message” are simply broad terms which can have multiple interpretations as to their meaning even within the art. If Applicant believes this to differentiate the claimed invention from prior art, Applicant is encouraged to amend the claim language to reflect this assertion that the “registration message or the configuration update message” is actually a NAS message (so long as there is sufficient support in the instant Specification for such an amendment). For these reasons, claims 1-3, 6, 10-12, 15, and 19-21 are rejected under 35 U.S.C. 102 and 35 U.S.C. 103. For more details about any of the above mentioned, please see the Claim Rejections section below.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

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.
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.
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.
Claims 3, 12, and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Chun (US 20220070815 A1), and further in view of 3GPP TR 22.831 V17.1.0.
Regarding claim 3, Chun teaches The network-changing method according to claim 1, as is described above.
Chun does not explicitly teach wherein determining that access to the second network is necessary comprises:
finding that the second network resumes to normal, wherein the terminal receives services from the second network before a disaster occurs in the second network, and accesses the first network after the disaster occurs in the second network.
However, 3GPP TR 22.831 V17.1.0 does teach wherein determining that access to the second network is necessary comprises:
finding that the second network resumes to normal, wherein the terminal receives services from the second network before a disaster occurs in the second network, and accesses the first network after the disaster occurs in the second network ([Page 10] Section 5.3.3, [Fig. 5.3.3-1], and [Fig. 5.3.3-2] the UE returns to hPLMN by performing PLMN selection; [Page 15] Sections 5.8.1-5.8.3 UE returns to home network after disaster period).
Chun and 3GPP TR 22.831 V17.1.0 are considered to be analogous to the claimed invention, as they are both in the same field of configuring a UE for disaster events. It would have been obvious to someone of ordinary skill in the art prior to the effective filing date of the claimed invention to have modified Chun to include the teachings of 3GPP TR 22.831 V17.1.0 where the UE returns to the home network when a disaster occurs. The rationale behind this would be to enhance user experience by minimizing the time gap between connection release and connection reestablishment ([Page 15] Section 5.8.1 3GPP TR 22.831 V17.1.0).
Regarding claim 12, Chun teaches The terminal according to claim 10, as is described above.
Chun does not explicitly teach wherein determining that access to the second network is necessary comprises:
finding that the second network resumes to normal, wherein the terminal receives services from the second network before a disaster occurs in the second network, and accesses the first network after the disaster occurs in the second network.
However, 3GPP TR 22.831 V17.1.0 does teach wherein determining that access to the second network is necessary comprises:
finding that the second network resumes to normal, wherein the terminal receives services from the second network before a disaster occurs in the second network, and accesses the first network after the disaster occurs in the second network ([Page 10] Section 5.3.3, [Fig. 5.3.3-1], and [Fig. 5.3.3-2] the UE returns to hPLMN by performing PLMN selection; [Page 15] Sections 5.8.1-5.8.3 UE returns to home network after disaster period).

The rationale behind this would be to enhance user experience by minimizing the time gap between connection release and connection reestablishment ([Page 15] Section 5.8.1 3GPP TR 22.831 V17.1.0).
Regarding claim 21, Chun teaches The non-transitory computer-readable storage medium according to claim 19, as is described above.
Chun does not explicitly teach wherein determining that access to the second network is necessary comprises:
finding that the second network resumes to normal, wherein the terminal receives services from the second network before a disaster occurs in the second network, and accesses the first network after the disaster occurs in the second network.
However, 3GPP TR 22.831 V17.1.0 does teach wherein determining that access to the second network is necessary comprises:
