Patent Description:
The Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of Things (loT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of Everything (IoE), which is a combination of the loT technology and the Big Data processing technology through connection with a cloud server, has emerged. As technology elements, such as "sensing technology", "wired/wireless communication and network infrastructure", "service interface technology", and "Security technology" have been demanded for loT implementation, a sensor network, a Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and so forth have been recently researched. Such an loT environment may provide intelligent Internet technology services that create a new value to human life by collecting and analyzing data generated among connected things.

In line with this, various attempts have been made to apply <NUM> communication systems to loT networks. Application of a cloud Radio Access Network (RAN) as the above-described Big Data processing technology may also be considered to be as an example of convergence between the <NUM> technology and the loT technology.

Currently, with the advancement in wireless communication technology, number of users accessing a wireless communication network has increased manifold times. The increased number of users of the wireless communication network has also brought in the need for optimizing resources of the wireless communication network to be able to serve the increased number of users.

Consider en example scenario where a user equipment (UE) which is dual subscriber identity module (SIM) and dual radio capable with a first transceiver being allocated to a first SIM and a second transceiver being allocated to a second SIM. When a call is initiated one the first SIM, then the second SIM is moved into an idle state with a data connectivity being suspended. However, due to the suspension of the second SIM, the second transceiver remains un-utilized which leads to loss of resources of the wireless communication network.

In another example scenario, consider the UE is dual subscriber identity module (SIM) and has a single transceiver. When the UE receives the call on the first SIM, then transceiver is allocated to the first SIM without informing the second SIM. Since, the second SIM is not aware about the call on the first SIM, the paging on the second SIM continues leading to un-necessary power consumption, which is not addressed.

<FIG> is a flow chart illustrating a method for suspending and resuming the downlink data associated with the first SIM when the voice call is initiated on the second SIM, according to an embodiment as disclosed herein.

At step <NUM>, the UE (<NUM>) determines the downlink data is operating on the first SIM (<NUM>).

At step <NUM>, the UE (<NUM>) suspends the downlink data on the first SIM (<NUM>) by sending the registration request with the MICO only mode on the first SIM (<NUM>) to the <NUM> network. At step <NUM>, the UE (<NUM>) initiates the voice call on the second SIM (<NUM>) of the UE (<NUM>). At step <NUM>, the UE (<NUM>) detects the incoming call directed towards the first SIM (<NUM>).

At step <NUM>, the UE (<NUM>) enables the dual smart SIM feature to receive the incoming call directed towards the first SIM (<NUM>) on the second SIM (<NUM>). At step <NUM>, the UE (<NUM>) determines that the voice call on the second SIM (<NUM>) has ended. At step <NUM>, the UE (<NUM>) resumes the downlink data on the first SIM (<NUM>) by sending the registration request with a non-MICO only mode on the first SIM (<NUM>) to the <NUM> network.

<FIG> illustrates a conventional mechanism for selecting one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) during an incoming call on the first SIM (<NUM>), according to a prior art.

Consider the UE (<NUM>) with a dual radio which supports dual registration on the second SIM (<NUM>) with a data distribution service (DDS) is active on the second SIM (<NUM>). At step <NUM>, both the first SIM (<NUM>) and the second SIM (<NUM>) are in idle mode i.e., there is no active session on both the first SIM (<NUM>) and the second SIM (<NUM>).

At step <NUM>, consider that the first SIM (<NUM>) receives the incoming call on the T1 (<NUM>). In the conventional methods and systems when there is the incoming call only one of the transceivers can be used by the first SIM (<NUM>) i.e., only T1 (<NUM>) can be used by the first SIM (<NUM>). However, there exists no procedure to determine whether the data service on the second SIM (<NUM>) should be provided by the <NUM> RAT or the <NUM> RAT on the T2 (<NUM>). Therefore, on the second SIM (<NUM>) both the <NUM> service and the <NUM> service is suspended.

<FIG> illustrates a mechanism for selecting one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) during the incoming call on the first SIM (<NUM>) based on the weighted score for the <NUM> RAT and the weighted score for the <NUM> RAT, as disclosed herein.

Referring to the <FIG>, in conjunction with the <FIG>, at step <NUM>, in the proposed method the UE (<NUM>) provides the data services dynamically by selecting one of the <NUM> RAT and the <NUM> RAT on the T2 (<NUM>) using the second SIM (<NUM>) based on the weighted score for the <NUM> RAT and weighted score for the <NUM> RAT.

In another embodiment, the UE (<NUM>) selects one of the <NUM> RAT and the <NUM> RAT on the T2 (<NUM>) based on the plurality of parameters associated with the <NUM> RAT and the <NUM> RAT.

<FIG> is an example illustrating a method for determination of the weighted score for the <NUM> RAT and the <NUM> RAT, and selection of one of the <NUM> RAT and the <NUM> RAT based on the weighted score, as disclosed herein.

Referring to the <FIG>, at step <NUM>, the weighted score for the <NUM> RAT and <NUM> RAT is determined based on the plurality of parameters. The plurality of parameters are at least one of voice availability for paging, the T2 Radio frequency (RF) chain availability during a voice call on the T1, a Radio Access Technology (RAT) interference, transmission power level, coverage of the <NUM> RAT, coverage of the <NUM> RAT, a user subscription, a home area, a roaming area, active protocol data unit (PDU) preference, quality of service (QOS) requirement, predicted data rate of the <NUM> RAT, predicted data rate of the <NUM> RAT, determined data rate of the <NUM> RAT and determined data rate of the <NUM> RAT, operator preferences and user preferences. The voice availability for paging parameter determines whether the voice is available on both the <NUM> RAT and the <NUM> RAT. The T2 Radio frequency (RF) chain availability during a voice call on the T1 parameter determines if the RF chain for both the <NUM> and the <NUM> RAT is available to T2 during the voice call on the T1. The RAT interference parameter determines an interference level of operating bands of each of the <NUM> and the <NUM> RAT with other band on the T1. The transmission power level determines whether the UE (<NUM>) is closer to the <NUM> or the <NUM> RAT which in turn will determine the UE (<NUM>) transmit power. The coverage of the <NUM> RAT and the coverage of the <NUM> RAT indicate whether both the <NUM> RAT and the <NUM> RAT provide the coverage to the UE (<NUM>). The user subscription parameter determines the user/operator preferred RAT for providing the data. The home or roaming area parameter determines the user/operator preferred RAT for providing the data in roaming. The active PDUs preference/QOS requirement parameter determines the PDUs active on the second SIM (<NUM>) has the QOS requirement of which of the <NUM> RAT and the <NUM> RAT. The predicted/determined data rates of each of the <NUM> RAT and the <NUM> RAT determine the average throughput on the <NUM> RAT and the <NUM> RAT.

Further, the weights associated with the each of the parameters of the plurality of parameters can be dynamically changed for each parameter based on the value of the parameter. For example, if voice availability for paging parameter is only available for the <NUM> RAT, then if Monitoring paging is needed as part of UE (<NUM>) implementation, then the voice availability for paging parameter will get <NUM>% weightage and the other parameters of the plurality of parameters will be given <NUM> weightage.

In another example, consider that the T2 (<NUM>) RF chain availability during voice call on the T1 (<NUM>) is available only for the <NUM> RAT, then the T2 (<NUM>) RF chain availability during voice call on the T1 (<NUM>) parameter will get <NUM>% weightage and the other parameters of the plurality of parameters will be given <NUM> weightage.

However in the examples described above, if the parameters considered are available for both the <NUM> RAT and the <NUM> RAT then the weightage of the parameters considered will become less and the other parameters of the plurality of parameters will be given higher weightage i.e., the weightage is assigned dynamically based on the implementation.

The weighted score for the <NUM> RAT and the weighted score for the <NUM> RAT are determined as follows:<MAT>
where W is a weight assigned to each parameter of the plurality of parameters used to determine the weighted score for the <NUM> RAT.

At step <NUM>, the UE (<NUM>) compares the weighted score for the <NUM> RAT and the weighted score for the <NUM> RAT.

Further, in response to determining that the weighted score for the <NUM> RAT is greater than the weighted score for the <NUM> RAT, the UE (<NUM>) selects the <NUM> RAT to occupy the T2 (<NUM>) (as shown in step <NUM>) and in response to determining that the weighted score for the <NUM> RAT is greater than the weighted score for the <NUM> RAT, the UE (<NUM>) selects the <NUM> RAT to occupy the T2 (<NUM>) (as shown in step <NUM>).

<FIG> is an example illustrating a method for selection of one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) during the incoming call on the first SIM (<NUM>) is performed based on the plurality of parameters associated with the <NUM> RAT and the <NUM> RAT, as disclosed herein.

In another example not encompassed by the wording of the claims, the data services dynamically provided on the second SIM (<NUM>) by selecting one of the <NUM> RAT and the <NUM> RAT based on at least one of the plurality of parameters associated with the <NUM> RAT and the <NUM> RAT. The at least one of the plurality of parameters associated with the <NUM> RAT and the <NUM> RAT is the user preferred RAT for application data, the operator preferred RAT for the application data, the user location preferred RAT for the application data, the user preferred RAT based on the called number, the user preferred RAT based on the calling number, the user preferred RAT based on the signal quality, the operator location preferred RAT for the application data, the operator preferred RAT based on the called number, the operator preferred RAT based on the calling number, the operator preferred RAT based on the signal quality, etc..

Referring to the <FIG>, the selection of one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) is done by considering at least one of the plurality of parameters associated with the <NUM> RAT and the <NUM> RAT. At step 301b, the UE (<NUM>) determines whether the user has defined any specific preferred RAT for providing the application data. In response to determining that the user has defined any specific preferred RAT for providing the application data, the UE (<NUM>) selects the user preferred RAT for providing the application data (step 304b). In response to determining that the user has not defined any specific preferred RAT for providing the application data, the UE (<NUM>) checks whether the operator has defined any specific preferred RAT for providing the application data (step 302b). In response to determining that the operator has defined any specific preferred RAT for providing the application data, the UE (<NUM>) selects the operator preferred RAT for providing the application data (step 304b). Similarly, at steps 303b, 305b, 306b and 307b, the UE (<NUM>) selects one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) based on the at least one parameter.

Further, the selection of one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) is performed based on one of the user preference or the operator preference.

<FIG> is a signaling diagram illustrating a method for selection of one of the <NUM> RAT and the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) during the incoming call on the first SIM (<NUM>) by a handover of the PDU from a Non-Active RAT to an active RAT, as disclosed herein.

Referring to the <FIG>, consider that the UE (<NUM>) is a dual radio capable dual SIM device. At step 301c, the UE (<NUM>) registers on the first SIM (<NUM>) in a single registration mode. In case the first SIM (<NUM>) is active, then the first SIM (<NUM>) uses the T1 (<NUM>).

At step 302c, the UE (<NUM>) registers the second SIM (<NUM>) with a Mobility Management Entity (MME) (<NUM>) of the second SIM (<NUM>) in the dual registration mode with dual radio. The second SIM (<NUM>) uses the T1 (<NUM>) on one of the <NUM> RAT and the <NUM> RAT.

Further, in case there is no event associated with the first SIM (<NUM>) then, the second SIM (<NUM>) latches to the <NUM> RAT on the T1 (<NUM>) and one of the second SIM (<NUM>) latches to the <NUM> RAT and the first SIM (<NUM>) will share the T2 (<NUM>) i.e., at step 303c, the UE (<NUM>) registers to the CORE network <NUM> using the first SIM (<NUM>) on the T2 (<NUM>). At step 304c, the UE (<NUM>) determines that the active session needs to be triggered on the first SIM (<NUM>) and at step 305c, the UE (<NUM>) initiates a voice call on the first SIM (<NUM>) on the T1 (<NUM>).

Further, the UE (<NUM>) selects one of the <NUM> RAT and the <NUM> RAT to use the T2 (<NUM>) based on one of the procedures described in the <FIG> and the <FIG>. Further, the PDUs on a Non-Active RAT are handed over to an active RAT or the PDUs on the Non-Active RAT are suspended. Consider that the UE (<NUM>) selects the <NUM> RAT to use the T2 (<NUM>), then the Protocol Data Unit (PDU) associated with the <NUM> RAT will be handed over to the <NUM> RAT by sending a PDU session establishment request to the <NUM> RAT. In the PDU session establishment request, the type is mentioned as handover to indicate to the <NUM> RAT to hand over the PDUs to the <NUM> RAT, as shown in steps 306c and step 307c.

At step 308c, the UE (<NUM>) determines that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended. In response to determining that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended, the UE (<NUM>) hands over the PDUs which was handed over from the <NUM> RAT to the <NUM> RAT back to the <NUM> RAT from which the PDUs were handed over to the <NUM> RAT, as shown in step 309c.

Therefore, in the proposed method the UE (<NUM>) will be able to provide one of the <NUM> service and the <NUM> service based on a requirement on the second SIM (<NUM>) even when there is the active session on the first SIM (<NUM>).

<FIG> is a signaling diagram illustrating a method for selection the <NUM> RAT for the second SIM (<NUM>) by the UE (<NUM>) during the incoming call on the first SIM (<NUM>) by suspending the <NUM> RAT, as disclosed herein.

Referring to the <FIG>, in conjunction with the <FIG>, steps 301d to 305d may be substantially the same as steps 301c to 305c, and, thus repeated description is omitted.

Consider that the UE (<NUM>) selects the <NUM> RAT to use the T2 (<NUM>), then the Protocol Data Unit (PDU) associated with the <NUM> RAT will be suspended. At step 306d, the UE (<NUM>) sends a Non-Access Stratum (NAS) message to suspend the PDUs associated with the <NUM> RAT.

Further, at step 307d, the UE (<NUM>) determines that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended. In response to determining that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended, the UE (<NUM>), at step 308d, resumes the <NUM> RAT.

Referring to the <FIG>, in conjunction to the <FIG>, steps 301e to 305e may be substantially the same as steps 301d to 305d, and, thus repeated description is omitted.

Consider that the UE (<NUM>) selects the <NUM> RAT to use the T2 (<NUM>), then the Protocol Data Unit (PDU) associated with the <NUM> RAT will be suspended. At step 306e, the UE (<NUM>) sends a Non-Access Stratum (NAS) message to suspend the PDUs associated with the <NUM> RAT.

Further, at step 307e, the UE (<NUM>) determines that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended. In response to determining that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended, the UE (<NUM>), at step 308e, resumes the <NUM> RAT.

<FIG> is a signaling diagram illustrating a method for optimizing the resources of the wireless communication network by suspending the <NUM> RAT and the <NUM> RAT associated with the second SIM (<NUM>) when the event is associated with the first SIM (<NUM>) occupying on the T1 (<NUM>), as disclosed herein.

Referring to the <FIG>, in conjunction to the <FIG>, steps 301f to 305f may be substantially the same as steps 301c to 305c, and, thus repeated description is omitted. The UE (<NUM>) determines a high interference with the voice call which is initiated on the T1 (<NUM>). In the proposed method, when there is high interference with the voice call on the T1 (<NUM>), the T2 (<NUM>) can be completely switched off by suspending both the <NUM> RAT and the <NUM> RAT on the T2 (<NUM>).

At step 306f, the UE (<NUM>) sends the NAS message to the <NUM> RAT and suspends the PDU associated with the <NUM> RAT and at step 307f, the UE (<NUM>) sends the NAS message to the <NUM> RAT and suspends the PDU associated with the <NUM> RAT. Further, at step 308f, the UE (<NUM>) determines that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended. In response to determining that the voice call on the first SIM (<NUM>) on the T1 (<NUM>) is ended, the UE (<NUM>), at step 309f, resumes both the <NUM> RAT and the <NUM> RAT.

<FIG> is a block diagram illustrating the UE (<NUM>) supporting dual SIM with dual radio, as disclosed herein.

Referring to the <FIG>, in an embodiment, a first communication processor ($<NUM>) and a second communication processor ($<NUM>) may be directly or indirectly connected to each other by an interface (not shown) to provide or receive data or control signals in either direction or in both directions.

A first RFIC ($<NUM>) may convert a baseband signal generated by the first communication processor ($<NUM>) into a radio frequency (RF) signal of about <NUM> to about <NUM> used in a first cellular network ($<NUM>) (e.g., a legacy network) at transmission. Upon reception, the RF signal may be obtained from the first cellular network (e.g., a legacy network) through an antenna (e.g., a first antenna module ($<NUM>)), and may be preprocessed through an RFFE (e.g., a first RFFE ($<NUM>)). The first RFIC ($<NUM>) may convert the preprocessed RF signal into a baseband signal so as to be processed by the first communication processor ($<NUM>).

A second RFIC ($<NUM>) may convert, upon transmission, a baseband signal generated by the first communication processor ($<NUM>) or the second communication processor ($<NUM>) into the RF signal (e.g., about <NUM> or less) in a sub-<NUM> band (e.g., a <NUM> Sub6 RF signal) used in the second cellular network ($<NUM>) (e.g., a <NUM> network). In reception, the <NUM> Sub6 RF signal may be obtained from the second cellular network ($<NUM>) (e.g., the <NUM> network) through an antenna (e.g., the second antenna module ($<NUM>), and preprocessed through the RFFE (e.g., a second RFFE ($<NUM>)). The second RFIC ($<NUM>) may convert the preprocessed <NUM> Sub6 RF signal into a baseband signal so that it can be processed by a corresponding communication processor among the first communication processor ($<NUM>) or the second communication processor ($<NUM>).

A third RFIC ($<NUM>) may convert the baseband signal generated by the second communication processor ($<NUM>) into the RF signal (hereinafter, an RF signal (hereinafter, about <NUM> to about <NUM>) of a <NUM> reserved ve6 band to be used in the second cellular network ($<NUM>) (e.g., a <NUM> conveve6 RF signal). In reception, the <NUM> enclove6 RF signal may be obtained from the second cellular network ($<NUM>) (e.g., a <NUM> network) through the antenna (e.g., an antenna ($<NUM>) and preprocessed through the third RFFE ($<NUM>). The third RFIC ($<NUM>) may convert the preprocessed <NUM> manipve6 RF signal into a baseband signal so as to be processed by the second communication processor ($<NUM>). According to another embodiment, the third RFFE ($<NUM>) may be formed as a part of the third RFIC ($<NUM>).

In another example not encompassed by the wording of the claims, the UE (<NUM>) may include a fourth RFIC ($<NUM>), separate from or at least a part of the third RFIC ($<NUM>). The fourth RFIC ($<NUM>) may convert the baseband signal generated by the second communication processor ($<NUM>) into the RF signal (hereinafter, an IF signal) of an intermediate frequency band (e.g., about <NUM> to about <NUM>), and then transmit the Intermediate Frequency (IF) signal to the third RFIC ($<NUM>). The third RFIC ($<NUM>) can convert the IF signal into a <NUM> conveve6 RF signal. At reception, the <NUM> enclove6 RF signal may be received from the second cellular network ($<NUM>) (e.g., the <NUM> network) through the antenna (e.g., an antenna ($<NUM>) and converted into the IF signal by the third RFIC ($<NUM>). The fourth RFIC ($<NUM>) can convert the IF signal into the baseband signal so that the second communication processor ($<NUM>) can be processed.

<FIG> is another block diagram illustrating the UE (<NUM>) supporting dual SIM with dual radio, as disclosed herein.

Referring to the <FIG>, in an example the first RFIC ($<NUM>) and the second RFIC ($<NUM>) may be implemented as at least part of a single chip or a single package. Also, the first RFFE ($<NUM>) and the second RFFE ($<NUM>) may be implemented as at least part of a single chip or a single package. Further, at least one antenna module among the first antenna module ($<NUM>) or the second antenna module ($<NUM>) may be omitted or coupled with another antenna module to process RF signals of the corresponding plurality of bands.

According to one example not encompassed by the wording of the claims, the third RFIC ($<NUM>) and the antenna ($<NUM>) may be disposed in the same sub frame to form the third antenna module ($<NUM>). For example, the wireless communication module (# <NUM>) or the processor (<NUM>) may be disposed on a first sub frame (e.g., a main PCB). In this case, a third RFIC ($<NUM>) may be disposed in some areas (e.g., a sub PCB) separate from the first sub frame (e.g., a sub PCB), and an antenna ($<NUM>) may be disposed in some other areas (e.g., the upper surface), and a third antenna module ($<NUM>) may be formed. It is possible to reduce the length of the transmission line there between by placing the third RFIC ($<NUM>) and the antenna ($<NUM>) in the same substrate. This may reduce, for example, a signal of a high frequency band (e.g., about <NUM> to about <NUM>) used for <NUM> network communication is lost (e.g., attenuated) by a transmission line. As a result, the UE (<NUM>) may improve the quality or speed of communication with the second cellular network ($<NUM>) (e.g., a <NUM> network).

Consider, the antenna ($<NUM>) may be formed of an antenna array including a plurality of antenna elements that may be used for beam forming. In this case, the third RFIC ($<NUM>) may include, for example, a plurality of phase shifters ($<NUM>) corresponding to a plurality of antenna elements, as part of the third RFFE ($<NUM>). At the time of transmission, each of the plurality of phase converters ($<NUM>) may convert the phase of the <NUM> conveve6 RF signal to be transmitted to the outside of the UE (<NUM>) (e.g., a base station of the <NUM> network) through a corresponding antenna element. At reception, each of the plurality of phase converters ($<NUM>) may convert the phase of the <NUM> conveve6 RF signal received from the outside into the same or substantially the same phase through a corresponding antenna element, which enables the transmission or the reception through the beam forming between the UE (<NUM>) and the above external.

The second cellular network ($<NUM>) (e.g., a <NUM> network) may be operated independently of the first cellular network ($<NUM>) (e.g., a legacy network) (e.g., Stand-Alone (SA)), connected and operated (e.g., Non-Stand Alone (NSA)). For example, the <NUM> network may have only an access network (e.g., a <NUM> radio access network (RAN) or a next generation RAN (NG RAN)), and may not have a core network (e.g., a next generation core (NGC)). In this case, the UE (<NUM>) may access an external network (e.g., the Internet) under control of a core network (e.g., a evolved core (EPC)) of the legacy network after accessing the access network of the <NUM> network. Protocol information (e.g., LTE protocol information) for communication with legacy networks or protocol information (e.g., New Radio (NR) protocol information for communication with <NUM> networks) may be stored in memory (<NUM>) and accessed by other parts (e.g., processor (<NUM>), first communication processor ($<NUM>), or second communication processor ($<NUM>).

In the invention when the RAT on both the first SIM (<NUM>) and the second SIM (<NUM>) is Idle, the first SIM (<NUM>) which is not supporting the <NUM> services will be using the RFIC $<NUM> to monitor the paging.

Similarly, if the second SIM (<NUM>) which supports the <NUM> services with the dual registration mode is also idle, then the second SIM (<NUM>) will be using the RFIC $<NUM> to monitor the paging if the <NUM> attached is Sub-<NUM>. If the <NUM> attached is mm wave, then the <NUM> attached will use the RFIC ($<NUM>) to monitor the paging.

In case of connected mode on the first SIM (<NUM>), then the first SIM (<NUM>) will use the RFIC ($<NUM>) to transmit and receive the data. At this time if the <NUM> is used on the second SIM (<NUM>), then the second SIM (<NUM>) will be using the RFIC ($<NUM>) to transmit and receive the data.

In case the <NUM> is used on the second SIM (<NUM>), then the second SIM (<NUM>) will be using the RFIC ($<NUM>) to transmit and receive the data if the frequency of the <NUM> is below <NUM>. If the frequency is above <NUM>, then the second SIM (<NUM>) will use the RFIC ($<NUM>) to transmit and receive the data.

<FIG> illustrates a conventional mechanism for handling paging operations for the UE (<NUM>) which is dual SIM capable with the single transceiver, according to a prior art.

Referring to the <FIG>, consider the UE (<NUM>) which is dual SIM capable with a single transceiver. The first SIM (<NUM>) and the second SIM (<NUM>) both support dual registration. Due to the dual registration capability on both the first SIM (<NUM>) and the second SIM (<NUM>), the UE (<NUM>) may have to handle a total of <NUM> paging operations i.e., two paging operations on the first SIM (<NUM>) and two paging operations on the second SIM (<NUM>). At <NUM>, the reading of <NUM> paging operations on the single transceiver may lead to <NUM>% power consumption in the idle mode.

<FIG> illustrates a method for optimizing power consumption by handling paging operations for the UE (<NUM>) which is dual SIM capable with the single transceiver, as disclosed herein.

Referring to the <FIG>, in conjunction with the <FIG>, the proposed method optimizes the power consumption and reduce the power consumption by <NUM>% by handling paging operations for the UE (<NUM>) which is dual SIM capable with the single transceiver.

In one example not encompassed by the wording of the claims, the UE (<NUM>) operates one of the first SIM (<NUM>) and the second SIM (<NUM>) in the dual registration mode and the other SIM in the single registration mode to reduce the number of paging messages. The UE (<NUM>) may determine the SIM to be operated in the dual registration mode based on the SIM on which the mobile data is set, the SIM on which the VoLTE only is supported and the VoNR is not supported, the SIM on which the critical <NUM> services are required, etc..

In another example not encompassed by the wording of the claims, the UE (<NUM>) operates both the first SIM (<NUM>) and the second SIM (<NUM>) in the single registration mode to reduce the number of paging messages, as the UE (<NUM>) needs to monitor paging for only two RATs thus reducing the idle mode power consumption by <NUM>%.

<FIG> illustrates a method for operating one of the first SIM (<NUM>) and the second SIM (<NUM>) in the dual registration mode when the event is associated with the first SIM (<NUM>), as disclosed herein.

Referring to the <FIG>, at step <NUM>, the UE (<NUM>) considers the first SIM (<NUM>) and determines whether the first SIM (<NUM>) supports the dual registration mode on the <NUM> network, at step <NUM>. At step <NUM>, the UE (<NUM>) determines whether at least one of the DDS is set on the first SIM (<NUM>), the first SIM (<NUM>) does not support the VONR, the first SIM (<NUM>) supports the VOLTE and the <NUM> critical services are requested in the first SIM (<NUM>).

In response to determining that the at least one of the DDS is set on the first SIM (<NUM>), the first SIM (<NUM>) does not support the VONR, the first SIM (<NUM>) supports the VOLTE and the <NUM> critical services are requested in the first SIM (<NUM>) is valid for the first SIM (<NUM>), at step <NUM>, the UE (<NUM>) operates the first SIM (<NUM>) in the dual registration mode and the second SIM (<NUM>) on the single registration mode.

In response to determining that the at least one of the DDS is set on the first SIM (<NUM>), the first SIM (<NUM>) does not support the VONR, the first SIM (<NUM>) supports the VOLTE and the <NUM> critical services are requested in the first SIM (<NUM>) is not valid for the first SIM (<NUM>), at step <NUM>, the UE (<NUM>) operates the first SIM (<NUM>) in the single registration mode and the second SIM (<NUM>) on the dual registration mode.

Similarly, the UE (<NUM>) at step <NUM> to step <NUM> determines whether the second SIM (<NUM>) is to be operated in one of the dual registration mode and the single registration mode.

Referring to the <FIG>, consider the UE (<NUM>) which is a DSDS Device with single radio and dual registration capability on both the first SIM (<NUM>) and the second SIM (<NUM>).

At step 401a, the UE (<NUM>) registers to the core network of the first SIM (<NUM>). The UE (<NUM>) registers to the core network of the first SIM (<NUM>) by sending the attach request which indicates that a dual registration is set on the first SIM (<NUM>). Further, the decision to select the SIM in which the dual registration is enabled is based on parameters are at least one of the SIM on which the VONR is not supported, the SIM on which the VOLTE is supported and the <NUM> critical services are required on the SIM.

Therefore, consider that the UE (<NUM>) registers on the first SIM (<NUM>) on the dual registration mode with the data/critical services on the <NUM> and the voice on the <NUM>.

At step 402a, the AMF (first SIM (<NUM>) CORE NW)-<NUM> (1400a) responds by sending a registration accept message with interworking without a N2G supported indication from the core network of the first SIM (<NUM>). At step 403a, the UE <NUM> triggers the attach request with the first SIM (<NUM>) network on the <NUM> and receives the attach accept message from the MME (first SIM (<NUM>) CORE NW)-<NUM> 1600a, at step 404a.

At step 405a, the UE (<NUM>) sends the registration request from the second SIM (<NUM>). Since, the DDS is not set on the second SIM (<NUM>), the second SIM (<NUM>) can operate only in the single registration mode. Further, the second SIM (<NUM>) will remain on the <NUM> if the VONR is supported, otherwise the second SIM (<NUM>) will switch to the <NUM> for the VOLTE.

At step 406a, the UE (<NUM>) receives the registration accept message with interworking without the N2G supported indication from the network. Thus, in the proposed method the first SIM (<NUM>) will be operating in the dual registration mode and the second SIM (<NUM>) will operate in the single registration mode, which will reduce the number of the paging operations to be monitored by the UE (<NUM>).

<FIG> illustrates a method for operating both the first SIM (<NUM>) and the second SIM (<NUM>) in the single registration for optimizing resources of the wireless communication network, as disclosed herein.

Referring to the <FIG>, at step <NUM>, the UE (<NUM>) considers the first SIM (<NUM>) and determines that the first SIM (<NUM>) supports dual registration and is currently latches to the <NUM> RAT, at step <NUM>. Further, at step <NUM>, the UE (<NUM>) configures the first SIM (<NUM>) to operate in the single registration mode. Further, at step <NUM>, the UE (<NUM>) determines whether the VONR is supported on the first SIM (<NUM>). In response to determining that the VONR is supported on the first SIM (<NUM>), at step <NUM>, the UE (<NUM>) continues to operate the first SIM (<NUM>) on the <NUM> RAT. In response to determining that the VONR is supported on the first SIM (<NUM>), at step <NUM>, the UE (<NUM>) switches to the <NUM> RAT and operates the first SIM (<NUM>) on the <NUM> RAT.

Similarly, the UE (<NUM>) repeats the procedure mentioned from step <NUM> to step <NUM>, for the second SIM (<NUM>) and configures the second SIM (<NUM>) to operate in the single registration mode.

<FIG> is a signaling diagram which illustrates a method for optimizing power consumption by handling paging operations for the UE (<NUM>) by operating the first SIM (<NUM>) in the single registration mode, as disclosed herein.

At step 410b, the UE (<NUM>) registers to the core network of the first SIM (<NUM>). The UE (<NUM>) registers to the core network of the first SIM (<NUM>) with <NUM> capability by sending the attach request which indicates that a single registration is set on the first SIM (<NUM>). Further, at step 412b, the UE (<NUM>) receives the registration accept message with interworking without the N2G supported indication from the network of the first SIM (<NUM>). The UE (<NUM>) determines whether the <NUM> RAT supports the VONR. In response to determining that the <NUM> network supports the VONR, the UE (<NUM>) continues to operate the first SIM (<NUM>) on the <NUM> network in the single registration mode. In response to determining that the <NUM> RAT does not support the VONR, the UE (<NUM>) switches to the <NUM> RAT with the VOLTE in the single registration mode by triggering the attach request with the first SIM (<NUM>) on the <NUM> RAT, at step 414b. Further, the UE (<NUM>) receives the attach accept response from the <NUM> RAT, at step 416b.

<FIG> is a signaling diagram which illustrates a method for optimizing power consumption by handling paging operations for the UE (<NUM>) by operating the second SIM (<NUM>) in the single registration mode, as disclosed herein.

At step 410c, the UE (<NUM>) registers to the core network of the second SIM (<NUM>). The UE (<NUM>) registers to the core network of the second SIM (<NUM>) with <NUM> capability by sending the attach request which indicates that a single registration is set on the second SIM (<NUM>) Further, at step 412c, the UE (<NUM>) receives the registration accept message with interworking without the N2G supported indication from the network of the second SIM (<NUM>) The UE (<NUM>) determines whether the <NUM> RAT supports the VONR. In response to determining that the <NUM> network supports the VONR, the UE (<NUM>) continues to operate the second SIM (<NUM>) on the <NUM> network in the single registration mode. In response to determining that the <NUM> RAT does not support the VONR, the UE (<NUM>) switches to the <NUM> RAT with the VOLTE in the single registration mode by triggering the attach request with the second SIM (<NUM>) on the <NUM> RAT, at step 414c. Further, the UE (<NUM>) receives the attach accept response from the <NUM> RAT, at step 416c.

Therefore, based on the <FIG> and the <FIG>, the UE (<NUM>) retains the registration of the first SIM (<NUM>) and the second SIM (<NUM>) only on that RAT which supports voice which is determined by the UE (<NUM>) based on a "IMS" PDU/PDN, which is indicated in the Table.

<FIG> illustrates a scenario of MO/MT call on one SIM leading to loss of resources of the wireless communication network due to paging on the other SIM, according to the prior art.

At <NUM>, the first SIM (<NUM>) is configured to provide data service on the <NUM> bearer and is in the connected mode, also the second SIM (<NUM>) is configured to provide voice service on any RAT and is in the idle mode.

At <NUM>, consider that the UE (<NUM>) receives a mobile terminated (MT) call or initiates a mobile originated (MO) call. The first SIM (<NUM>) does not have any TRM resource but the eNB (<NUM>) is not informed of the MO/MT call on the second SIM (<NUM>) which is occupied the transceiver. Hence, a lot of paging resources are wasted on the network side. The second SIM (<NUM>) is active due to the MO/MT call and the transceiver is occupied by the second SIM (<NUM>). Therefore, there is no existing method for the UE (<NUM>) to suspend the operations on the first SIM (<NUM>) when there is an ongoing MO/MT call on the second SIM (<NUM>) and then resume the operations after the MO/MT call ends.

<FIG> illustrates a method of optimizing the resources when the MO/MT call is ongoing on one SIM of the dual SIM UE (<NUM>), as disclosed herein.

Referring to the <FIG>, in conjunction with the <FIG>, at step <NUM>, when the MO/MT call is ongoing on the second SIM (<NUM>), the UE (<NUM>) indicates to the eNB (<NUM>) that the first SIM (<NUM>) is not occupying the transceiver and hence no paging needs to be done on the first SIM (<NUM>). Due to the UE (<NUM>) informing the eNB (<NUM>) about the first SIM (<NUM>) being idle, the paging resources are saved as the eNB (<NUM>) suspends the data connectivity on the first SIM (<NUM>), thereby optimizing the power and paging resources at the wireless communication network.

Further, at <NUM>, the UE (<NUM>) determines that the MO/MT call is ended on the second SIM (<NUM>) and indicates the wireless communication network to resume the data connectivity with the first SIM (<NUM>). Also, the voice service is available at the second SIM (<NUM>) even after the MO/MT call has ended.

<FIG> is a signaling diagram which illustrates a method for optimizing the resources of the wireless communication network by suspending and resuming the downlink data when the event is associated with the second SIM (<NUM>), according to an embodiment as disclosed herein.

At step <NUM>, the UE (<NUM>) registers with the <NUM> RAT on the first SIM (<NUM>) and at step <NUM>, the UE (<NUM>) registers with the core network using one of the <NUM> RAT and the <NUM> RAT on the second SIM (<NUM>). At step <NUM>, consider that the UE (<NUM>) needs to trigger the voice call on the second SIM (<NUM>) and the UE (<NUM>) determines that the downlink data is operating on the first SIM (<NUM>). In response to determining that the downlink data is operating on the first SIM (<NUM>), the UE (<NUM>) sends a registration request with a mobile initiated connection only (MICO) mode on the first SIM (<NUM>) to the <NUM> RAT for suspending the downlink data on the first SIM (<NUM>). Further, the UE (<NUM>) receives the registration accept with MICO mode from the <NUM> RAT, at step <NUM>.

At step <NUM>, the UE (<NUM>) initiates the voice call on the second SIM (<NUM>) and monitors the voice call. At step <NUM>, the UE (<NUM>) determines that the voice call on the second SIM (<NUM>) is ended. In response to determining that the voice call on the second SIM (<NUM>) is ended, at step <NUM>, the UE (<NUM>) sends a registration request with a non- mobile initiated connection only (non-MICO) mode on the first SIM (<NUM>) to the <NUM> RAT for resuming the downlink data on the first SIM (<NUM>). Further, the UE (<NUM>) receives the registration accept with non-MICO mode from the <NUM> RAT, at step <NUM>.

In another embodiment, during the suspension of the downlink data on the first SIM (<NUM>) a dual smart SIM feature can be enabled so that any MT calls coming to the first SIM (<NUM>) are not lost and can be received on the second SIM (<NUM>).
