Newer generation, e.g., fourth generation (4G) and fifth generation (5G) , cellular wireless networks employing newer radio access technology that implements one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) and LTE Advanced (LTE-A) standards are rapidly being developed and deployed by network operators worldwide. The newer cellular wireless networks provide a range of packet-based services for both voice and data in parallel. A user of anelectronic device can access services offered by a wireless network service provider, also referred to as a mobile network operator (MNO) , based on service subscriptions controlled by authentication credentials included in a profile, also referred to as a subscriber identity module (SIM) , when included in a removable universal integrated circuit card (UICC) , or as an electronic SIM (eSIM) , when included in an embedded UICC (eUICC) of the electronic device. With a removable UICC and an unlocked electronic device, a user can access different services by replacing the UICC/SIM combination. With a configurable eUICC, eSIMs can be downloaded to the eUICC for access to different wireless services. Electronic devices that accommodate multiple UICCs/SIMs and/or multiple eSIMs on an eUICC provide for multiple subscriber identities to be used by the same electronic device to access different services, including services that can span different cellular wireless networks that use different cellular radio access technologies (RATs) .

However, when to change adefault data subscription (DDS) of the electronic device and what the DDS is switched to arealways based on user’s decision and user’s experience, and the DDS is also changed manually, which is inconvenient and inaccurate.

DETAILED DESCRIPTION

In order for those skilled in the art to better understand technical solutions of implementations, technical solutions of implementations will be described clearly and completely with reference to accompanying drawings in the implementations. Apparently, implementations hereinafter described are merely some implementations, rather than all implementations, of the disclosure. All other implementations obtained by those of ordinary skill in the art based on the implementations herein without creative efforts shall fall within the protection scope of the disclosure.

The terms “first” , “second” , “third” , and the like used in the specification, the claims, and the accompany drawings of the disclosure are used to distinguish different objects rather than describe a particular order. The terms “include” , “include” , and “have” as well as variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus including a series of steps or units is not limited to the listed steps or units. Instead, it can optionally include other steps or units that are not listed; alternatively, other steps or units inherent to the process, method, product, or apparatus can also be included.

The term “implementation” referred to herein means that a particular feature, structure, or character described in conjunction with the implementation may be contained in at least one implementation of the disclosure. The phrase appearing in various places in the specification does not necessarily refer to the same implementation, nor does it refer to an independent or alternative implementation that is mutually exclusive with other implementations. It is explicitly and implicitly understood by those skilled in the art that an implementation described herein may be combined with other implementations.

Anelectronic devicereferred to herein may include various handheld devices, in-vehicle devices, wearable devices, computing devices that have wireless communication functions or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) , mobile stations (MS) , mobile terminals, and the like. For ease of description, the above-mentioned devices are collectively referred to as anelectronic device.

It is very common that one electronic device has multiple SIM cards for use. A user of the electronic device may have multiple subscriptions due to separated business or personal purposes, prepaid or postpaid subscriptions, cheaper data plans, home or roaming for travelling, different services supported by different carriers. However, the user needs to change the default data subscription (DDS) manually based on his/her experience. For a specific example, if a user is experiencing a slow or poor internet access on the DDS, he/she would switch the DDS. Currently, DDS selection is based on the user’s decision and is performed through user interface (UI) settings. Reference can be made to FIG. 1, whichillustratesUI settings of the DDS.

The followings are exemplaryproblem scenarios where DDS switch needs to be performed. Assume that data throughput is relatively faster in high-orderradio access technology (RAT) and in good radio channel conditions.

Problematicscenario 1

The electronicdevice camps on lower priority RAT on DDS but higher priority RAT is available on non-DDS. For example, the electronic device camps on LTE on DDS but 5G RAT is available on non-DDS.

Problematicscenario 2

Radio channel conditions on DDS is not good as on non-DDS. For example, signal strength and signal quality on DDS are worse than that on non-DDS.

Problematic scenario 3

Actual data throughput on DDS is slower than on non-DDS. The actual data throughput includes speed and latency on each subscription that can be measured when the electronic device is in an idle mode or in RRCconnected mode periodically.

Problematicscenario 4

Internet service is unavailable on the DDS due to various reasons. As the electronic device is getting complicated, sometimes user is experiencing Internet service unavailability due to data stall (caused by packet lost) , data volume being reached to a limitation, failed registration/attach, or public data network (PDN) connection being rejected, which will cause that the electronic device might be in limited service.

Implementations of the present disclosure provide a method for dynamic switch of a default data subscription, which can perform dynamic DDS switch and improving user experience. By means of the implementations, a better DDS selection can be made in a multi-SIM scenario, data performance can be improved, and internet service unavailability can be addressed as well.

For ease of better understanding of implementations of the present disclosure, related technology involved in the present disclosure will be briefly introduced below.

Hereinafter, detailed description of implementations of the present disclosure will be given below.

FIG. 2 is a schematic flowchart of a method fordynamic switch of a default data subscription according to implementations. As illustrated in FIG. 2, the method fordynamic switch of a default data subscription includes the following.

At block 202, for each of multiple subscriber identity module (SIM) cards of an electronic device, signal parameter information of each of at least one available RAT is detected.

Modem radio protocol stacks are able to monitor thesignal parameter information on non-DDS at the same time without performing DDS switch to the non-DDS. The signal parameter includes at least one of signal quality and signal strength. The signal strength is measured by reference signal received power (RSRP) , and the signal quality is measured by reference signal received quality (RSRQ) .

At block 204, multiple scores are obtainedbased on the signal parameterinformation of each of at least one available RAT.

Specifically, themultiple scores are obtained by determining a score of each of the at least one available RAT based on the signal parameter information thereof.

As an implementation, themultiple scores are obtainedbased on the signal parameterinformation of each of at least one available RATby obtaining the multiple scores based on both a type of the each of the at least one available RAT and the signal parameter information thereof. Specifically, the multiple scores can be obtained by determining a score based on both a type of the each of the at least one available RAT and the signal parameter information thereof. The signal parameter information may be interpreted as information of a signal parameter. The signal parameter may include at least one signal quality and signal strength.

Specifically, the score of each of the at least one available RAT is determined based on both the RAT and the signal parameter information thereof. For example, the score may be determined based on a first score and a second score, where the first score is determined based onthe RAT and the second score is determined based on the signal parameter information of the RAT. Different RATs correspond to different first scores. The signal parameter informationmay be divided into three levels, such as, excellent (or good) , fair, and poor. Different signal parameter informationcorresponds to different second scores. The final score may be a sum of the first score and the second score or a weighted sum of the first score and the second score, which is not limited herein.

For another example, the score of each of the at least one available RAT can also be determined as following. A pre-defined score is given to each subscription per RAT availability and radio channel conditions initially. Thescore of each of the at least one available RAT can be determined by adjusting the initial score based on the RAT and signal parameter information of the RAT separately. Reference can be made to table 1 and table 2, where table 1 illustrates a correspondence between different RATs anddifferentscoreadjustments, and table 2 illustrates a correspondence between different channel conditions anddifferentscoreadjustments. Taking the initial score being equal to 100 points (pts) as an example, a score corresponding to an RAT “5G” and signal parameter information “excellent” may be 100+10+6, which is 116 pts.

Table 1

RAT	Score
5th Generation Mobile Communication Technology (5G)	+10
4th Generation Mobile Communication Technology (4G)	+5
3th Generation Mobile Communication Technology (3G)	+2.5
2th Generation Mobile Communication Technology (2G) or Out of service (OOS)	+0

Table 2

Signal parameter information	Score
Excellent (or good)	+6
Fair	+3
Poor	+0

The score of each of the at least one available RAT can also be determined by adjusting the initial score based on the RAT and signal parameter information of the RAT comprehensively. Reference can be made to table 3, where table 3 illustrates a correspondence between different combinations of RATs andchannel conditionsand differentscoreadjustments. Taking the initial score being equal to 100 points (pts) as an example, a score corresponding to an RAT “5G” and signal parameter information “excellent” may be 100+15 which is 115 pts.

Table 3

For example, based on table 3, the DDS with 4G good coverage is more preferred than 5G poor coverage.

After the score of each of the at least one available RAT is determined based on the signal parameter information thereof, the score may be furtheradjusted or penalized when at least one abnormal event is detected.

At block 206, a default data subscription (DDS) of the electronic device is switched to a target RAT of a target SIM card according to the multiple scores, where the target SIM card is one of the multiple SIM cards.

In implementations of the present disclosure, for each of multiple SIM cards of an electronic device, signal parameter information of each of at least one available RAT is detected. Multiple scores are obtainedbased on the signal parameterinformation of each of at least one available RAT. A DDS of the electronic device is switched to a target RAT of a target SIM card according to the multiple scores, where the target SIM card is one of the multiple SIM cards. As such, the DDS of the electronic device can be switched automatically without user-interface (UI) settings of a user, which is convenient and can simply the process of DDS switch. In addition, the DDS switch can be performed objectively based on the score of each of the at least one available RAT of each of the multiple SIM cards instead of based on the experience of the user, which can improve the accuracy of the DDS switch.

As an implementation, the method further includes the following. After the DDS of the electronic device is switched to the target RAT of the target SIM card, a timer is set, and the target RAT of the target SIM card is camped on until the timer expires.

Because protocol service (PS) data may be not available intermittently during DDS switch, the timer is set to avoid frequent DDS switch between two subscriptions (i.e., two SIM cards or two RATs) .

As an implementation, the method further includes the following. After the DDS of the electronic device is switched to the target RAT of the target SIM card and before a timer is set, the electronic device is detected to move at a moving speed greater than a threshold or the electronic device is detected to be located at an edge area of a cell.

When the electronic device moves at a moving speed greater than a threshold or the electronic device is located at an edge area of a cell, frequent DDS switch may be performed. Therefore, upon detecting that the electronic device moves at a moving speed greater than a threshold or the electronic device is located at an edge area of a cell, the timer is set to avoid frequent DDS switch between two subscriptions (i.e., two SIM cards or two RATs) and further avoid intermittent PS availability of PS data during DDS switch.

As an implementation, the method further includes the following. After the DDS of the electronic device is switched to the target RAT of the target SIM card, at least one abnormal event is detected, and a score of the target RAT of the target SIM card is updated according to the at least one abnormal event detected.

Specifically, after a score of each of the at least one available RAT is determined based on a RAT andasignal parameter information, the score may also be further adjusted and updated according to the at least one abnormal event detected. The updated score can be used for a basis of DDS switch next time.

As an implementation, the at least one abnormal event includes at least one of: unavailable PS data, temporary data stall, and slower data throughput on DDS than on non-DDS.

Specifically, the at least one abnormal event may be classified into at least three types, i.e., unavailable PS data, temporary data stall, and slower data throughput on DDS than on non- DDS. For different types of abnormal events, a score of the target RAT of the target SIM card may be adjusted in different in amplitudes. For example, an adjustment amplitude when the unavailable PS data is detected is larger than an adjustment amplitude when the temporary data stall is detected, and the adjustment amplitude when the temporary data stall is detected is larger than an adjustment amplitude when the slower data throughput on DDS than on non-DDS is detected. Reference can be made to table 4, which illustrates adjustment amplitudes corresponding to different abnormal event.

Table 4

Abnormal event	Score adjustment
unavailable PS data	To 0
temporary data stall	-3
slower data throughput on DDS than on non-DDS	-5

As an implementation, the data throughput includes at least one of: data transmission speed and data transmission latency.

As an implementation, when the at least one abnormal event includes slower data throughput on DDS than on non-DDS, the at least one abnormal event can be detected as following. A detecting interval is determined according to at least one of a connection state and a moving state of the electronic device. The data throughput on DDS is detected to be slower than on non-DDS at any detecting interval.

Specifically, the electronic device may have a system application of (e.g., a tool such as ping, and iperf) which is used to measure data performance (i.e., throughput) on each subscription periodically or in response to an event. When the electronic device is in different states, the detecting interval may be different. For example, the detecting interval when the electronic device is in an idle mode is different from a detecting interval when the electronic device is in an RRC connected mode, and a detecting interval when the electronic device is in a static state is also different from a detecting interval when the electronic device is in a mobile state.

As an implementation, the connection state includes one of: an idle mode and a radio resource control (RRC) connected mode, and a detecting interval when the electronic device is in the idle mode is longer than a detecting interval when the electronic device is in the RRC connected mode.

When the electronic device is in the idle mode, a detecting period (i.e., a detecting interval) would be longer to avoid frequent wakeup of the electronic device which could increase power compulsion of the electronic device.

As an implementation, the moving state includes one of: a static state (stationary) and a mobile state (mobility) , and a detecting interval when the electronic device is in the static state is longer than a detecting interval when the electronic device is in the mobile state.

When the electronic device is in the static state, a detecting period (i.e., a detecting interval) would be longer to avoid frequent detection which could increase power compulsion of the electronic device.

As an implementation, the unavailable PS data includes at least one of: permanent data stall, data volume limit being reached, RAT registration being rejected, Internet public data network (PDN) connection being rejected, failed authentication, and the DDS being in limited service.

As an implementation, asignal parameterincludes at least one of signal quality and signal strength.

As an implementation, the signal strength is measured by reference signal received power (RSRP) , and the signal quality is measured by reference signal received quality (RSRQ) .

For example, thesignal parameter information may be divided into three levels, such as, excellent (or good) , fair, and poor according to RSRP and RSRQ, which can be better seen from table 5, which illustrates a correspondence between levels of signal parameter information and RSRP and RSRQ.

Table 5

Signal parameter information	RSRQ (dB)	RSRP (dbM)
Excellent (or good)	＞-9	＞-85
Fair	-12 to-9	-103 to-111
Poor	＜-12	＜-111

As an implementation, the DDS of the electronic device is switched to the target RAT of the target SIM card periodically or upon detecting a request for data transmission through network.

FIG. 3 is a schematic flowchart of a method fordynamic switch of a default data subscription according toother implementations. As illustrated in FIG. 3, the method fordynamic switch of a default data subscription includes the following.

At block 302, for each of multiple subscriber identity module (SIM) cards of an electronic device, signal parameter information of each of at least one available RAT is detected.

At block 304, multiple scores are obtainedbased on the signal parameterinformation of each of at least one available RAT.

At block 306, a DDS of the electronic device is switched to a target RAT of a target SIM card according to the multiple scores, where the target SIM card is one of the multiple SIM cards.

After the DDS of the electronic device is switched to the target RAT of the target SIM card, operations at blocks 308-312 andoperations at blocks 314-316 can be performed in parallel. Operations at blocks 308-312 aim to avoid frequent DDS switch between two subscriptions (i.e., two SIM cards or two RATs) and further avoid intermittent PS availability of PS data during DDS switch, andoperations at blocks 314-316 aim to update the sore the target RAT of the target SIM card according to at least one abnormal event detected

At block 308, the electronic device is detected to move at a moving speed greater than a threshold or the electronic device is detected to be located at an edge area of a cell.

At block 310, a timer is set.

At block 312, the target RAT of the target SIM card is camped on until the timer expires.

At block 314, at least one abnormal event is detected.

At block 316, a score of the target RAT of the target SIM card is updated according to the at least one abnormal event detected.

In implementations of the present disclosure, for each of multiple SIM cards of an electronic device, signal parameter information of each of at least one available RAT is detected. A score of each of the at least one available RAT is determined based on the signal parameter information thereof, to obtain multiple scores. A DDS of the electronic device is switched to a target RAT of a target SIM card according to the multiple scores, where the target SIM card is one of the multiple SIM cards. As such, the DDS of the electronic device can be switched automatically without user-interface (UI) settings of a user, which is convenient and can simply the process of DDS switch. In addition, the DDS switch can be performed objectively based on the score of each of the at least one available RAT of each of the multiple SIM cards instead of based on the experience of the user, which can improve the accuracy of the DDS switch.

In addition, since PS data may be not available intermittently during DDS switch, the timer is set to avoid frequent DDS switch between two subscriptions (i.e., two SIM cards or two RATs) .

In addition, after a score of each of the at least one available RAT is determined based on a RAT andasignal parameter information, the score may also be further adjusted and updated according to the at least one abnormal event detected. The updated score can be used for a basis of DDS switch next time.
