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.
Claims 6-7 and 16-17 are rejected under 35 U.S.C. 103 as being unpatentable over Gudivada et al. (US 2022/0377658) in view of Shukair et al. (US 2023/0180170) in further view of Xie et al. (US 2023/0362978).
Regarding Claim 6, Gudivada teaches the invention of Claim 2, but does not teach modifying, by the second SIM, a measurement report to switch to the target cell to make the apparatus support the DSDA mode; transmitting, by the second SIM, the modified measurement report to a second serving cell; and switching, by the second SIM, from the second serving cell to the target cell based on a handover procedure to perform the second service.
Shukair, in the same field of endeavor, teaches modifying, by the second SIM, a measurement report to switch to the target cell to make the apparatus support the DSDA mode; (Par. [0072] “In cases where the UE 115-a is configured for communications associated with each SIM, the UE 115-a may adjust configured communications, such as by reporting a radio link failure (RLF) to reduce a number of secondary CCs (SCCs) in a CA configuration, by adapting RI and CQI to reduce or increase throughput requests, by adapting RF measurement reports to add one or more SCCs, by utilizing a network capability exchange, by adapting a buffer status report (BSR) associated with one or more of the SIMs to reduce network uplink grants, or any combinations thereof”), transmitting, by the second SIM, the modified measurement report to a second serving cell; (Par. [0067] “Based on a determined resource partition, the UE 115-a may transmit a first indication of supported communication parameters associated with the first SIM 230 in measurement report 255 to the first base station 105-a, and may transmit a second indication of supported communication parameters associated with the second SIM 235 to the second base station 105-b”),
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to incorporate Gudivada’s dual SIM apparatus with Shukair’s measurement reports to produce an expected result of efficiency when a dual SIM device has entered the DSDA mode.
Gudivada in view of Shukair, however, does not teach switching, by the second SIM, from the second serving cell to the target cell based on a handover procedure to perform the second service.
Xie, in the same field of endeavor, teaches switching, by the second SIM, from the second serving cell to the target cell based on a handover procedure to perform the second service (Fig. 8C, Par. [0132] “In FIG. 8C, after the UE determining to change the second connection 824 as discussed above, the UE 802 has changed the second connection 824 for the second SIM 806 by performing a handover from the first base station 812 (e.g., using the first frequency resource) to the second base station 814 (e.g., using the second frequency resource)”).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Gudivada’s dual SIM apparatus as combined with Shukair’s measurement reports with Xie’s SIM switching to a target cell to produce an expected improvement in efficiency when a dual SIM device has entered the DSDA mode.
Regarding Claim 7, Gudivada teaches the invention of Claim 2, further comprising, performing, by the second SIM, the second service from a second serving cell (Par.

Shukair, in the same field of endeavor, teaches modifying, by the first SIM, a measurement report to switch to the target cell to make the apparatus support the DSDA mode; (Par.

Shukair, in the same field of endeavor, teaches the processor further being configured to modify, via the second SIM, a measurement report to switch to the target cell to make the apparatus support the DSDA mode, (Par. [0072] “In cases where the UE 115-a is configured for communications associated with each SIM, the UE 115-a may adjust configured communications, such as by reporting a radio link failure (RLF) to reduce a number of secondary CCs (SCCs) in a CA configuration, by adapting RI and CQI to reduce or increase throughput requests, by adapting RF measurement reports to add one or more SCCs, by utilizing a network capability exchange, by adapting a buffer status report (BSR) associated with one or more of the SIMs to reduce network uplink grants, or any combinations thereof”), and transmit, via the second SIM, the modified measurement report to a second serving cell, (Par. [0067] “Based on a determined resource partition, the UE 115-a may transmit a first indication of supported communication parameters associated with the first SIM 230 in measurement report 255 to the first base station 105-a, and may transmit a second indication of supported communication parameters associated with the second SIM 235 to the second base station 105-b”).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to incorporate Gudivada’s dual SIM apparatus with Shukair’s measurement reports to produce an expected result of efficiency when a dual SIM device has entered the DSDA mode.
Gudivada in view of Shukair, however, does not teach teaches switching, via the second SIM, from the second serving cell to the target cell based on a handover procedure to perform the second service.

Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Matolia discloses “When an application requires use of a network slice available via a first SIM/eSIM and the application also requires minimal interruption while in use, the dual-SIM/eSIM wireless device can switch from the DSDS mode to the DSDA mode while the application is in use. In the DSDA mode, the dual-SIM/eSIM wireless device can maintain a data connection for the application via the first SIM/eSIM and originate or terminate voice calls (or other voice and/or data connections) via the second SIM/eSIM without interrupting the application. The dual-SIM/eSIM wireless device can also use the DSDA mode temporarily to perform network search and/or radio measurements of wireless networks when operating in an area of limited cell service or weak signal strength for a second SIM/eSIM and one or more applications with high priority data connections via the first SIM/eSIM are in use, in order to minimize communication interruptions by the second SIM/eSIM activities impacting the one or more applications using the first SIM/eSIM” (Par. [0036]).
