CTFR 17/653,412 CTFR 86456 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Response to Arguments On pg. 13, par. 1 of Applicant’s Response, applicant argues that however, HUANG describes that the selection of the first RAT, in step 1506, can be based on a set of aspects, but HUANG does not disclose that the handover is step 1514 is based on any conditions. Thus, HUANG does not disclose or suggest "transition, based at least in part on at least one condition... a communication link carrying a protocol data unit (PDU) session from the second subscription to the first subscription," as recited in amended claim 1. Examiner respectfully disagrees with applicant’s argument. Huang states in par. 128, “At operation 1514, the UE 702 hands over the connection with the second IMS (~IP Multimedia Subsystem) server (e.g., the IMS service 714-2) (~using IMS (IP Multimedia Subsystem) in a 5G network, a dedicated PDU (Protocol Data Unit) session is established to carry the IMS voice and video traffic) from the second RAT to the first RAT or the third RAT”, wherein the handover from the second RAT (~second subscription) to the first RAT (~first subscription) (~step 1514 of Fig. 15) is based at least in part on at least one condition (~step 1512 of Fig. 15 - communicate, under the first subscriber identity, with a first IP Multimedia Subsystem (IMS) server of the first network through the first RAT to establish the first call) or can be based on any of the previous steps prior to step 1514 of Fig. 15 (~any of the previous steps are conditions for step 1514 to occur) since the step 1514 only occurs if the previous steps occur. To reiterate, step 1506 of Fig. 15 (~selecting based on condition) is also a condition (~previous step) required for step 1514 of Fig. 15 (~hand over from second RAT(~second subscription) to first RAT (~first subscription)) to occur. Huang states in par. 124, “At operation 1506, the UE 702 selects , in a first performance configuration, the first RAT to establish a first call under the first subscriber identity (e.g., the SIM1 702-1). In certain configurations, RAT is selected based on at least one of a call quality, a cost to make the first call, a power consumption (~condition associated with a device configuration of the UE) of the UE, and a handover rate”; wherein the transition from the second subscription (~SIM2) to the first subscription (~SIM1) is based on selecting the first subscription (~SIM1) and is thus based on the condition for selecting the first subscription (~SIM1) . The transition (step 1514 of Fig. 15) is based on the selection (step 1506 of Fig. 15), the selection (step 1506 of Fig. 15) is based on the conditions, and thus the transition (step 1514 of Fig. 15) is based on the conditions. Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 3. 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. 07-20-aia AIA 4. 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. 07-21-aia AIA 5. Claim s 1, 6-8, 17-20, 25, 30-32, and 35-36 are rejected under 35 U.S.C. 103 as being unpatentable over Huang (US 2019/0110236 A1) in view of Chen (US 2018/0368099 A1) . Regarding claim 1, Huang teaches an apparatus for wireless communication at a user equipment (UE) ([0122], “wireless communication of a UE 702”) , comprising: one or more memories; and one or more processors, coupled to the one or more memories (Fig. 26, processor(s) 2604 coupled to computer-readable medium/memory 2606) , configured to: communicate using a first radio access technology (RAT) for a first subscription of the UE ([0124], “At operation 1506, the UE 702 selects, in a first performance configuration, the first RAT to establish a first call under the first subscriber identity (e.g., the SIM1 702-1) ”; [0127], “UE 702 communicates, under the first subscriber identity , with a first IMS server (e.g., the IMS service 714-1) of the first network through the first RAT to establish the first call”) , wherein the first RAT is selected from a group that includes a first cellular RAT associated with the first subscription, a second cellular RAT associated with a second subscription of the UE, and a wireless local area network (WLAN) RAT ([0123], “UE 702 determines whether the set includes a first RAT (e.g., the RAT-1 826) accessing a base station (e.g., the base station 704-1) in the first network , a second RAT (e.g., the RAT-2 822) accessing a base station (e.g., the base station 704-2) in the second network , and a third RAT (e.g., the RAT-3 824) accessing an access point of a WLAN (e.g., the WLAN network 716)”; [0122], “ a first subscriber identity (~first subscription) (e.g., SIM1 702-1) associated with a first network (e.g., the mobile network 791) and a second subscriber identity (~second subscription) (e.g., SIM2 702-2) associated with a second network (e.g., the mobile network 792)” ); communicate using a second RAT for the second subscription of the UE ([0140], “At operation 1706, the UE 702 communicates, under the second subscriber identity (~second subscription) , with the second IMS server through the second RAT (e.g., RAT-2 822) to establish the second call”) , wherein the second RAT is selected from the group that includes the first cellular RAT associated with the first subscription, the second cellular RAT associated with the second subscription of the UE, and the WLAN RAT ([0123], “UE 702 determines whether the set includes a first RAT (e.g., the RAT-1 826) accessing a base station (e.g., the base station 704-1) in the first network , a second RAT (e.g., the RAT-2 822) accessing a base station (e.g., the base station 704-2) in the second network , and a third RAT (e.g., the RAT-3 824) accessing an access point of a WLAN (e.g., the WLAN network 716)”; [0122], “ a first subscriber identity (~first subscription) (e.g., SIM1 702-1) associated with a first network (e.g., the mobile network 791) and a second subscriber identity (~second subscription) (e.g., SIM2 702-2) associated with a second network (e.g., the mobile network 792)” ); and transition, based at least in part on at least one condition, a communication link carrying a protocol data unit (PDU) session from the second subscription to the first subscription ([0128], “At operation 1514, the UE 702 hands over the connection with the second IMS (~IP Multimedia Subsystem) server (e.g., the IMS service 714-2) (~using IMS (IP Multimedia Subsystem) in a 5G network, a dedicated PDU (Protocol Data Unit) session is established to carry the IMS voice and video traffic) from the second RAT to the first RAT or the third RAT”, wherein the handover from the second RAT (~second subscription) to the first RAT (~first subscription) (~step 1514 of Fig. 15) is based at least in part on at least one condition (~step 1512 of Fig. 15 - communicate, under the first subscriber identity, with a first IP Multimedia Subsystem (IMS) server of the first network through the first RAT to establish the first call) or can be based on any of the previous steps prior to step 1514 of Fig. 15 (~any of the previous steps are conditions for step 1514 to occur) since the step 1514 only occurs if the previous steps occur ; To reiterate, step 1506 of Fig. 15 (~selecting based on condition) is also a condition (~previous step) required for step 1514 of Fig. 15 (~hand over from second RAT(~second subscription) to first RAT (~first subscription)) to occur; [0124], “At operation 1506, the UE 702 selects , in a first performance configuration, the first RAT to establish a first call under the first subscriber identity (e.g., the SIM1 702-1). In certain configurations, RAT is selected based on at least one of a call quality, a cost to make the first call, a power consumption (~condition associated with a device configuration of the UE) of the UE, and a handover rate”; wherein the transition from the second subscription (~SIM2) to the first subscription (~SIM1) is based on selecting the first subscription (~SIM1) and is thus based on the condition for selecting the first subscription (~SIM1) ; The transition is based on the selection, the selection is based on the conditions, and thus the transition is based on the conditions ) . Huang does not explicitly teach that the transition is based at least in part on the first subscription being a default data subscription (DDS) and the second subscription being a non-DDS subscription. However, Chen teaches transition is based at least in part on a first subscription being a default data subscription (DDS) and a second subscription being a non-DDS subscription (Based on a condition that a first subscription is a DDS and a second subscription a non-DDS ([0074], “a subscription associated with SIM card 215-a may be a DDS subscription and a subscription associated with SIM card 215-b may be a non-DDS subscription”) , a communication session transitions to the first DDS subscription from the second non-DDS subscription ([0074], “ The DDS subscription may dynamically or temporarily be switched for multimedia messaging service (MMS) (~PDU) reception ”, wherein the switch (~transition) is from the non-DDS subscription ) ; [0074], “one subscription may be prioritized over other subscriptions in dual SIM UEs 115. For example, a subscription associated with SIM card 215- a may be prioritized over the subscription associated with SIM card 215- b ... a subscription associated with SIM card 215- a may be a DDS subscription and a subscription associated with SIM card 215- b may be a non-DDS subscription ...

Services that support voice calls only are often referred to as voice-only services or non-DDS services. Such subscription schemes may be elected or chosen based on data/voice plan costs and/or reliability (~wherein the default data subscription is chosen based on data/voice plan costs and/or reliability) ”, wherein on a dual SIM mobile device, a dedicated data subscription (DDS) is set as the default data subscription, allowing users to designate one specific SIM for all mobile data usage while potentially using the other SIM for calls and messages ) . It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to combine the teaching of Chen with the teaching of Huang in order to have a pre-selected data plan that is automatically applied to a user's account essentially acting as the standard data option for their service, providing a baseline data usage amount without requiring manual selection each time they need to subscribe to a plan as well as a separate mobile data plan that is not automatically used by your device, allowing you to choose which data plan to use depending on your needs. Regarding claim 6, Huang in view of Chen teaches the apparatus of claim 1, wherein the at least one condition further comprises that a voice call is active on the first subscription (Huang [0110], “At beginning 1316, a SIM1 call is active . More specifically, at 1318, SIM1 call is active on SIM1 RAT-OPT-A 1306”; [0127], “At operation 1512, the UE 702 communicates, under the first subscriber identity , with a first IMS server (e.g., the IMS service 714-1) of the first network through the first RAT to establish the first call ”; [0090], “ SIM1 702-1 is used to have a voice call ”) , and that voice over WLAN service is enabled on the second subscription ([0111], “Then SIM2 voice-over-WiFi (VoWifi) mobile terminating call occurs at 1322”; [0110], “ SIM2 1304 is using the WLAN network 716”; [0119], “UE 702 can hand over SIM1 call to the WLAN network”; [0080], “under the subscriber identity of SIM2 702-2, the UE 702 can access the mobile network 792 through the WLAN network ”) . Regarding claim 7, Huang in view of Chen teaches the apparatus of claim 1, wherein the at least one condition further comprises that a voice call is active on the second subscription (Huang [0112], “ SIM2 call can become an active call ”; [0111], “ SIM2 voice ... call ”; [0080], “under the subscriber identity of SIM2 702-2”; [0140], At operation 1706, the UE 702 communicates, under the second subscriber identity , with the second IMS server through the second RAT (e.g., RAT-2 822) to establish the second call ”) , and that voice over WLAN service is enabled on the second subscription (Huang [0111], “Then SIM2 voice-over-WiFi (VoWifi) mobile terminating call occurs at 1322”; [0110], “ SIM2 1304 is using the WLAN network 716”; [0119], “UE 702 can hand over SIM1 call to the WLAN network”; [0080], “under the subscriber identity of SIM2 702-2, the UE 702 can access the mobile network 792 through the WLAN network ”) . Regarding claim 8, Huang in view of Chen teaches the apparatus of claim 1, wherein the at least one condition further comprises that voice over WLAN service is disabled on the second subscription (Huang [0111], “SIM2 voice-over-WiFi (VoWifi) mobile terminating call occurs at 1322”; [0112], “Then at 1326, UE can hold SIM1 call and pick up SIM2 call, so that SIM2 call can become an active call. More specifically, a performance centric mechanism is applied at 1328, and SIM2 call becomes active on SIM2 RAT-OPT-A 1312 (~a voice-over-WiFi (VoWifi) is no longer active and instead a mobile network is now active) and thus the voice over WLAN service is disabled on the second subscription (~SIM2)) ; Note: Huang [0109], “where SIM2 RAT-OPT-A 1312 refers to a RAT accessing the SIM's own network, i.e., the mobile network 792”) ; [0114], “ To keep active call performance, SIM2 call need to be transferred to mobile network, i.e., the mobile network 792. Thus, at 1338, connection of SIM2 1304 is handed over to SIM2 RAT-OPT-A 1312”, wherein the handover of the SIM2 1304 (~second subscription) to SIM2 RAT-OPT-A 1312 (~first subscription) based on a condition that a voice-over-WiFi (VoWifi) is disabled ) . Regarding claim 17, Huang in view of Chen teaches the apparatus of claim 1, wherein at least one of the first RAT for the first subscription or the second RAT for the second subscription is selected based at least in part on (Huang [0124], “the first RAT is selected based on at least one of a call quality, a cost to make the first call, a power consumption of the UE, and a handover rate”) at least one of: a user setting stored by the UE; a RAT preference associated with at least one of the first cellular RAT, the second cellular RAT, or the WLAN RAT; at least one of an availability of the first cellular RAT, an availability of the second cellular RAT, or an availability of the WLAN RAT; or a signal quality measured for at least one of the first cellular RAT, the second cellular RAT, or the WLAN RAT (Huang [0124], “the first RAT is selected based on at least one of a call quality, a cost to make the first call, a power consumption of the UE, and a handover rate”) . Regarding claim 18, Huang in view of Chen teaches the apparatus of claim 1, wherein the one or more processors (Huang Fig. 26, processor(s) 2604) are further configured to: monitor at least one of availability or signal quality for at least one of the first cellular RAT, the second cellular RAT, or the WLAN RAT (Huang [0123], “UE 702 determines whether the set includes a first RAT (e.g., the RAT-1 826) accessing a base station (e.g., the base station 704-1) in the first network, a second RAT (e.g., the RAT-2 822) accessing a base station (e.g., the base station 704-2) in the second network, and a third RAT (e.g., the RAT-3 824) accessing an access point of a WLAN (e.g., the WLAN network 716)”) ; select a different RAT, than the selected RAT, based at least in part on monitoring at least one of the availability or the signal quality (Huang [0124], “the first RAT is selected based on at least one of a call quality, a cost to make the first call, a power consumption of the UE, and a handover rate”; [0107], “applying performance centric mechanism 1226 includes that SIM2 IMS service is transferred to the IMS service 714-2, at 1228. In other words, SIM2 call is using its own network, i.e., the mobile network 792, and therefore, a better voice/video quality can be achieved. More specifically, at 1230, a PDN handover request is sent to the mobile network 792”) ; and communicate on the first subscription using the selected different RAT ([0127], “At operation 1512, the UE 702 communicates, under the first subscriber identity, with a first IMS server (e.g., the IMS service 714-1) of the first network through the first RAT to establish the first call”) . Regarding claim 19, Huang in view of Chen teaches the apparatus of claim 1, wherein the communication link carrying the PDU session includes at least one of an evolved packet data gateway tunnel or a non-3GPP interworking function tunnel (Huang [0119], “IPsec (~non-3GPP) tunnel setup”, wherein IPsec establishes a secure tunnel between a user device and the network through a "Non-3GPP Interworking Function" (N3IWF) in 5G networks ) .

Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Huang in view of Chen, and further in view of White (US 2015/0365820 A1) . Regarding claim 16, Huang in view of Chen teaches the apparatus of claim 1, wherein the one or more processors (Huang Fig. 26, processor(s) 2604) are further configured to establish a tunnel to a home network of the UE, via a network connection with another UE (Huang [0077], “the UE 702 may establish a secure tunnel over the WLAN network 716 with the ePDG 718. With the help of the ePDG 718 and the WLAN network 716, the UE 702 can communicate with the UE 703 via both the WLAN network 716 and the PDN gateway 708-2 of the mobile network 792 corresponding to SIM2 702-2”) .. The combination does not explicitly teach that the establishing of the tunnel is based at least in part on detecting a loss of cellular coverage for the UE. However, White teaches establishing of a connection is based at least in part on detecting a loss of cellular coverage for the UE ([0016-0017], “The mobile station may not be connected to the cellular network for several reasons ... due to the mobile station being in a geographic area with poor cellular coverage ... Upon determining that the mobile station is not presently connected to the cellular network, the device management server signals a home subscriber server (HSS) to update a user equipment profile for the mobile station to indicate that the mobile station has a pending device management session. The mobile station may connect to a first network either in real-time (e.g., without any intentional delay) or a time period (e.g., 10 minutes, 1 hour, 12 hours, etc.) after the HSS updates the user equipment profile for the mobile station”) . It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to combine the teaching of White with the teaching of Huang as modified by Chen in order to enable continued data transfer, allowing of sending and receiving messages, accessing the internet, and making calls even when cellular signal is weak or absent.
