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 of this title, 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.
7. Claims 1-5, 8, 10, 12-16, 18, 23-24 and 26 are rejected under 35 U.S.C. 103 as being unpatentable over Nie et al. (US 2020/0383024 A1), hereinafter “Nie” in view of DASH et al. (US 2023/0085782 A1), hereinafter “Dash”.
Regarding claim 1, Nie discloses a method of wireless communication performed by a user equipment (UE) (Figs. 5, 15, 18, methods for a wireless device to detect and operate in an elevator or elevator-like conditions), comprising:
using a second radio access technology (RAT) (paragraphs [0006], [0068], [0074], [0076], [0098], out of service condition or non-preferred RAT) responsive to a combination of sensor values (paragraphs [0006], [0068], [0074], [0076], [0098], combinations of conditions, such as signal strength and/or service availability based conditions and motion detection based conditions) satisfying respective coverage hole thresholds (paragraphs [0006], [0068], [0074], [0076], [0098], signal strength threshold over specified time window or acceleration pattern relates to start pattern, run pattern and stop pattern) associated with a coverage hole (paragraphs [0006], [0068], [0074], [0076], [0098], conditions associated with entering and/or being inside of an elevator) of a first RAT (paragraphs [0006], [0068], [0074], [0076], [0098], normal mode or preferred RAT), the combination of sensor values including at least one non-radio sensor value (paragraphs [0006], [0068], [0074], [0076], [0098], motion detection based conditions); and
reconnecting to the first RAT (paragraphs [0086], [0105], the wireless device may operate in a normal mode, e.g., with respect to cellular communication, e.g., based at least in part on detecting the one or more conditions associated with exiting an elevator) responsive to at least one sensor value of the sensor values no longer satisfying its respective coverage hole threshold (paragraphs [0086], [0105], another possible modification, for e.g. Fig.18: exiting an elevator is correlated with an increased likelihood of availability of LTE service, such an approach may result in the wireless device more quickly regaining LTE service than if the wireless device were to continue with its ongoing search pattern, at least in some instances ).
Assuming Arguendo that Nie does not explicitly disclose or strongly suggest: “reconnecting to the first RAT responsive to at least one sensor value of the sensor values no longer satisfying its respective coverage hole threshold”, Dash from the same or similar field of endeavor explicitly discloses reconnecting to the first RAT responsive to at least one sensor value of the sensor values no longer satisfying its respective coverage hole threshold (Fig. 1, paragraph [0022], UE can communicate in the first RAT for service by a first public land mobile network (PLMN); when the first RAT is not available, the UE communicates in a second RAT for service by a second PLMN; the UE can further determine whether to switch back from the second RAT to the first RAT, which may be referred to as the reselection of the first RAT).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “reconnecting to the first RAT responsive to at least one sensor value of the sensor values no longer satisfying its respective coverage hole threshold” as taught by Dash, in the system of Nie, so that it would provide reselection of a radio access technology for a multi-mode user equipment supporting multiple RATs in response to a determination that there is the trigger event to enable the UE to switch from the second RAT to the first RAT (Dash, paragraph [0002]).
Regarding claim 2, Nie discloses the combination of sensor values satisfying respective coverage hole thresholds (paragraphs [0006], [0068], [0074], [0076], [0098], signal strength threshold over specified time window or acceleration pattern relates to start pattern, run pattern and stop pattern)) comprises a radio sensor value satisfying a radio coverage hole threshold and the at least one non-radio sensor value satisfying at least one non-radio coverage hole threshold (paragraphs [0006], [0068], [0074], [0076], [0098], combinations of conditions, such as signal strength and/or service availability based conditions and motion detection based conditions).
Regarding claim 3, Nie discloses the one or more sensor values include at least one non-radio sensor value includes an accelerometer value, a proximity sensor value, a barometric pressure value, a light sensor value, a positioning value, a microphone input value, or any combination thereof (Fig. 15, paragraphs [0076], [0098], an accelerator component, a gyroscope component, and/or any of various other possible motion sensing components could be used to help detect a wireless device motion pattern that is considered characteristic of being in an elevator).
Regarding claim 4, Nie discloses the coverage hole of the first RAT comprises an elevator, a tunnel, a below-ground floor, underground parking, or a subway (paragraphs [0006], [0068], one or more conditions associated with entering and/or being inside of an elevator).
Regarding claim 5, Nie in view of Dash disclose the method according to claim 1.
Dash further discloses the first RAT service is a New Radio (NR) service and the second RAT service is a Long Term Evolution (LTE) service (paragraphs [0005], [0024], [0029], first RAT includes NR and second RAT includes LTE).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “the first RAT service is a New Radio (NR) service and the second RAT service is a Long Term Evolution (LTE) service” as taught by Dash, in the system of Nie, so that it would provide reselection of a radio access technology for a multi-mode user equipment supporting multiple RATs in response to a determination that there is the trigger event to enable the UE to switch from the second RAT to the first RAT (Dash, paragraph [0002]).
Regarding claim 8, Nie in view of Dash disclose the method according to claim 5.
Dash further discloses reconnecting to the first RAT includes, if an available NR neighbor is found, prioritizing NR frequencies, prioritizing scheduling of NR measurements, opening an autonomous gap for NR measurements, triggering local fast redirection to the first RAT, or any combination thereof (Figs. 1, 3, 4, paragraphs [0024], [0054]-[0055], mechanisms for the reselection of a RAT so that the UE can quickly return to the RAT previously used, which can save power and improve the performance; A UE can communicate in a first RAT for service by a first PLMN. When the first RAT is not available, and the UE communicates in the second RAT for service by a second PLMN; Before switching to the second RAT, the UE can store information about the first RAT for the first PLMN; The saved information can include a specific mobile country code (MCC) for the first PLMN and a specific mobile network code (MNC) for the first PLMN; The saved information about the first RAT for the first PLMN can be used later for the reselection of the first RAT for the first PLMN without searching for a PLMN blindly; For example, the UE can search whether a cell in the first RAT for the first PLMN is available for the UE to camp on when the UE decides to switch back to the first RAT).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “reconnecting to the first RAT includes, if an available NR neighbor is found, prioritizing NR frequencies, prioritizing scheduling of NR measurements, opening an autonomous gap for NR measurements, triggering local fast redirection to the first RAT, or any combination thereof” as taught by Dash, in the system of Nie, so that it would provide reselection of a radio access technology for a multi-mode user equipment supporting multiple RATs in response to a determination that there is the trigger event to enable the UE to switch from the second RAT to the first RAT (Dash, paragraph [0002]).
Regarding claim 10, Nie in view of Dash disclose the method according to claim 5.
Dash further discloses reconnecting to the first RAT service includes, if no available NR neighbor is found: triggering a background public land mobile network search; and connecting to the NR service if an NR cell is found (Fig.3, paragraphs [0055], [0057], PLMN selection and cell selection performed at the background; background selection is different from a foreground cell selection process where UE 101 does a MAKE with the new PLMN in terms of camping before BREAK with the previous PLMN in which it was camped in GSM/UMTS/LTE RAT).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “reconnecting to the first RAT service includes, if no available NR neighbor is found: triggering a background public land mobile network search; and connecting to the NR service if an NR cell is found” as taught by Dash, in the system of Nie, so that it would provide reselection of a radio access technology for a multi-mode user equipment supporting multiple RATs in response to a determination that there is the trigger event to enable the UE to switch from the second RAT to the first RAT (Dash, paragraph [0002]).

8. Claims 6-7, 17 and 22 are rejected under 35 U.S.C. 103 as being unpatentable over Nie et al. (US 2020/0383024 A1), hereinafter “Nie” in view of DASH et al. (US 2023/0085782 A1), hereinafter “Dash” in view of Frangooles et al. (US 2023/0164593 A1), hereinafter “Frangooles”.
Regarding claim 6, Nie in view of Dash disclose the method according to claim 5.
While Nie in view of Dash implicitly refer to “the first RAT service is provides a standalone NR service”, Frangooles s from the same or similar field of endeavor explicitly discloses the first RAT service is provides a standalone NR service (paragraphs [0014], [0031], [0037], network implementations may support standalone architectures, non-standalone architectures, dual connectivity, carrier aggregation, etc.).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “the first RAT service is provides a standalone NR service” as taught by Frangooles, in the combined system of Nie and Dash, so that it would provide improved bandwidth and faster response time to multiple network devices (Frangooles, paragraph [0001]).

9. Claims 9, 11, 19-21 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Nie et al. (US 2020/0383024 A1), hereinafter “Nie” in view of DASH et al. (US 2023/0085782 A1), hereinafter “Dash” in view of Nishant et al. (US 2022/0150807 A1), hereinafter “Nishant”.
Regarding claim 9, Nie in view of Dash disclose the method according to claim 5.
Neither Nie nor Dash explicitly discloses “reconnecting to the first RAT triggers an acquisition database scan starting from NR, aborting LTE registration, or any combination thereof”.
However, Nishant from the same or similar field of endeavor discloses reconnecting to the first RAT triggers an acquisition database scan starting from NR, aborting LTE registration, or any combination thereof (Fig. 11, paragraphs [0036]-[0037], [0095], [0144], [0148], handling frequency scanning in wireless communication network).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “reconnecting to the first RAT triggers an acquisition database scan starting from NR, aborting LTE registration, or any combination thereof” as taught by Nishant, in the combined system of Nie and Dash, so that it would provide faster 5G camping experience to a user of the UE to optimize a new radio (NR) frequency scanning (Nishant, paragraph [0008]).
Regarding claim 11, Nie in view of Dash disclose the method according to claim 1.
Neither Nie nor Dash explicitly discloses “the first RAT provides a New Radio (NR) service in frequency range 1 (FR1) and the second RAT provides an NR service in FR2, or the first RAT provides a New Radio (NR) service in frequency range 2 (FR2) and the second RAT provides an NR service in FR1”.
However, Nishant from the same or similar field of endeavor discloses the first RAT provides a New Radio (NR) service in frequency range 1 (FR1) and the second RAT provides an NR service in FR2, or the first RAT provides a New Radio (NR) service in frequency range 2 (FR2) and the second RAT provides an NR service in FR1 (Fig. 11, paragraphs [0036]-[0037], [0095], [0144], [0148], FR1 Time Division Duplexing (TDD) bands as defined in 38.101-01 are as wide as 900 MHz (Band n77) shown in the table 1; in another example, FR2 TDD Bands as defined in 38.101-02 are as wide as 3250 MHz (Band n258) shown in the table 2).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to provide “the first RAT provides a New Radio (NR) service in frequency range 1 (FR1) and the second RAT provides an NR service in FR2, or the first RAT provides a New Radio (NR) service in frequency range 2 (FR2) and the second RAT provides an NR service in FR1” as taught by Nishant, in the combined system of Nie and Dash, so that it would provide faster 5G camping experience to a user of the UE to optimize a new radio (NR) frequency scanning (Nishant, paragraph [0008]).
