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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 October 26, 2025 has been entered.
This Office Action is in response to RCE application filed on December 10, 2025 and wherein claims 15, 16, 27, 28, 33 and 34 being currently amended, claims 19, 31 and 37 being canceled.
In virtue of this communication, claims 15-18, 20, 27-30, 32-36 and 38 are currently pending in this Office Action.
The Office appreciates the explanation of the amendment and analyses of the prior arts, and however, although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993) and MPEP 2145.
Response to Applicant’s Reply
Applicant’s arguments with respect to claim(s) 15, 27, 33 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.
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.
4. Claims 15-16,18, 20, 27-28, 30, 32-34, 36 and 38 are rejected under 35 U.S.C. 103 as being unpatentable over Luo et al. (US 20230024741 A1, hereinafter Luo) and in view of Ahn et al. (US 20220053426 A1, hereinafter Ahn).
Claim 15: Luo teaches a network connection control method, applied to a terminal (Abstract, Fig. 16, element 131), wherein the method comprises:
detecting, by the terminal, that link quality of a data link of the terminal does not meet a specified quality condition (Fig. 16, element 1610, [0291-0297], disclose 7 examples that not meet the preset condition, battery power of the terminal device is greater than the first preset value, the temperature of the rear cover of the terminal is less than the second preset value, terminal device in the non-power saving mode and etc.);
a dual connectivity function is not activated (Fig. 16, element “Use an LTE link for communication”, [0301], “when the terminal device 131 detects that the 5G switch of the terminal device 131 is in the disabled state, the terminal device 131 may perform the foregoing step 330”) and the terminal is not in a voice call state;
and in response to the detecting and the not being activated, performing, when the dual connectivity function is not activated and the terminal is not in the voice call state, a first operation to activate the dual connectivity function of the terminal, wherein the first operation is disconnecting, by the terminal, from a 4G network in an access network (Fig. 16, elements 1640a, 1641a, 1642a, [0305-0307], disclose releasing a bearer established between the LTE access network device 121 and the terminal device 131 corresponding to the detached request message), and requesting to reconnect to a 5G network and the 4G network in the access network (Fig. 16, element 1645A, 1646A, 1647A, 1648A, 1649A ,1650, [0313], “The terminal device 131 sends a second attach request message to the LTE access network device 121, where the second attach request message carries NR capability information, the second attach request message includes an identifier of the terminal device 131, and the second attach request message is used to request to perform an attach operation based on the identifier of the terminal device 131”, [0315], “if the second attach request message carries the NR capability information, a field in the second attach request message indicates that the terminal device supports the NR capability …establishing the bearer between the LTE access network device 121 and the terminal device 131, and establishing the bearer between the NR access network device 122 and the terminal device 131”).

Luo and Ahn are both considered to be analogous to the claimed invention because they are in the same field of wireless communication. Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to modify a condition for activating the dual connectivity DC function, disclosed by Luo, to enable DC connection when terminal is not in a voice call state, as taught by Ahn, for the benefit of avoiding transmitting a large amount of data through 5G wireless communication when an application is not preset to transmit voice data through the 5G wireless communication scheme ([0181]).
Claim 27 is analyzed and rejected according to claim 15 and Luo further teach a computer-readable storage medium, wherein the computer- readable storage medium stores instructions, and when the instructions are executed on a terminal ([0371], “The computer storage medium stores a computer instruction. When the computer instruction is run on a terminal device”).
Claim 33 is analyzed and rejected according to claim 15 and Luo further teach a terminal comprising at least one processor (Fig.20, element 2010, [0368], “The processing module may be a processor or a controller”) and at least one memory(Fig.20, element 2010,[0370], “ the apparatus may include a connected processor, memory, and communications module”), the memory comprising instructions that, when executed by the processor ([0370], “The memory is configured to store a computer executable instruction. When the apparatus runs, the processor may execute the computer executable
instruction stored in the memory, so that the chip performs the communication methods in the foregoing method embodiments”).

and accessing the core network corresponding to the access network by using a secondary base station in the access network, to activate the dual connectivity function (Fig. 16, element 1648a, 1649a, 1650,[0318], “The LTE access network device 121 receives a second attach accept message sent by the core network device 111, where the second attach accept message is used to indicate that the second attach request for the terminal device 131 has been completed”, [0320], “the NAS layer of the terminal device 131
receives the second attach accept message sent by the LTE access network device 121”, [0323], “where the second attach request message is used to request to restore the radio resource that is occupied on the NR access network device side and that is configured for the connection between the terminal device and the NR access network device 122, thereby implementing restoration of the NR link. After the NR link is restored, the LTE link and the NR link are used for communication”).
Claim 30 is analyzed and rejected according to claim 27 and claim 18.
Claim 36 is analyzed and rejected according to claim 33 and claim 18.
Claim 20: Luo teaches the method according to claim 16, wherein the enabling, by the terminal, the dual connectivity function of the terminal after disabling the dual connectivity function of the terminal for first disabling duration comprises:
reporting, by the terminal, a secondary cell group failure to a master base station in the access network, to disconnect from a secondary base station in the access network and disable the dual connectivity function (Fig. 6B, Element 350a, [0202], “Step 350a: The terminal device 131 sends a first detach request message to the LTE access network device 121. The first detach message includes the identifier of the terminal device 131, and the first detach request message is used to request to perform a detach operation based on the identifier of the terminal device 131, so as to release the NR link”, wherein detach request message serving the similar function as reporting a secondary cell group failure to a master base station.

Claim 32 is analyzed and rejected according to claim 28 and claim 20.
Claim 38 is analyzed and rejected according to claim 34 and claim 20.
Claims 17, 29, 35 are rejected under 35 U.S.C. 103 as being unpatentable over Luo et al. (US 20230024741 A1, hereinafter Luo) and in view of Ahn et al. (US 20220053426 A1, hereinafter Ahn) and further in view of Wallen et al. (US 20220279401 A1, hereinafter Wallen).
Claim 17: Luo teach the method according to claim 15, wherein the detecting, by the terminal, that link quality of the data link of the terminal does not meet the specified quality condition comprises at least one of the following:
detecting, by the terminal, that the terminal receives no downlink data packet or sends no uplink data packet in a first preset transmission duration (alternative); and
