Description

Dynamic switching method of DDS (direct digital synthesizer) of default data subscription and related products

Technical Field

The disclosure relates to the technical field of communication, in particular to a dynamic switching method of a default data subscription DDS and related products.

Background

Network operators worldwide are rapidly developing and deploying new generation technologies, such as fourth generation mobile communication technology (4G) and fifth generation mobile communication technology (5G), and cellular wireless networks employing new radio access technologies to implement at least one of the third generation partnership project (3 GPP) standard, the Long Term Evolution (LTE) standard, and the LTE evolution (LTE-a) standard. The new cellular wireless network provides a series of packet-based services for voice and data in parallel. Based on the service subscription controlled by the authentication credentials included in the profile, a user of the electronic device may access services provided by a wireless network service provider, also known as a Mobile Network Operator (MNO). The authentication credentials are 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 an electronic device. Using the removable UICC and the unlocked electronic device, the user can access different services by replacing the UICC/SIM combination. With a configurable eUICC, multiple esims can be downloaded to the eUICC to access different wireless services. An electronic device that installs multiple UICCs/SIMs and/or downloads multiple esims on an eUICC provides multiple user identities that are used by the same electronic device to access different services, including services that may span different cellular wireless networks using different cellular Radio Access Technologies (RATs).

However, when to change the Default Data Subscription (DDS) of the electronic device and what subscription to switch to is always based on the decision of the user and the experience of the user, and the DDS needs to be changed manually, thus being inconvenient and inaccurate.

Detailed Description

In order to make the solution of the embodiments better understood by those skilled in the art, the technical solution of the present embodiment will be clearly and completely described below with reference to the accompanying drawings in the present embodiment, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, based on this embodiment, which would be apparent to one of ordinary skill in the art without undue burden are intended to be within the scope of this application.

The terms first, second, third and the like in the description and in the claims of the present application and in the above-described figures, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. Such as a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to those listed but may alternatively include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The electronic device according to the embodiments of the present application may include various handheld devices, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Stations (MS), mobile terminals, etc. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices.

It is common for one electronic device to use multiple SIM cards. A user of an electronic device may have multiple subscriptions due to independent business or personal purposes, pre-or post-paid subscriptions, cheaper packages of data, home or travel roaming, different services supported by different operators, etc. However, the user needs to manually change the DDS according to his own experience. For example, if the user has slow or no internet access on the DDS, he/she will switch DDS. Currently, DDS selection is based on a user's decision and is performed through UI settings. Referring to fig. 1, fig. 1 shows UI settings of the DDS.

The following is an exemplary problem scenario in which DDS handoff needs to be performed. It is assumed that data throughput is relatively large under high priority RATs and good radio channel conditions.

Problem scenario 1

The electronic device resides on a low priority RAT as a DDS, but is available on a high priority RAT that is not a DDS. For example, the electronic device resides in LTE as DDS, but a 5G RAT that is not DDS is available.

Problem scenario 2

The radio channel conditions of DDS are not as good as those of non-DDS. For example, the signal strength and signal quality of a DDS is inferior to that of a non-DDS.

Problem scenario 3

The actual data throughput of the DDS is smaller than the actual data throughput of the non-DDS. The actual data throughput includes a speed and delay for each subscription, which may be periodically measured when the electronic device is in idle mode or Radio Resource Control (RRC) connected mode.

Problem scenario 4

For various reasons, the internet service of the DDS is not available. As electronic devices become more complex, users may experience unavailability of internet services due to data stalls caused by packet loss, limited data volume, registration/connection failures, or rejected Public Data Network (PDN) connections, which may result in the electronic devices being in a service limited state.

The embodiment of the application provides a dynamic switching method of DDS, which can execute dynamic DDS switching and improve user experience. By the embodiment, better DDS selection can be made in a multi-SIM card scene, the data performance can be improved, and the problem that internet service is not available can be solved.

In order to facilitate a better understanding of the embodiments of the present application, the related art referred to in the present application will be briefly described below.

Embodiments of the present application will be described in detail below.

Fig. 2 is a schematic flowchart of a dynamic switching method of a DDS according to an embodiment. As shown in fig. 2, the dynamic switching method of the DDS includes the following.

202, for each of a plurality of SIM cards of an electronic device, signal parameter information for each of at least one available RAT is detected.

The modem wireless protocol stack can monitor signal parameter information of the non-DDS simultaneously without performing DDS handoff 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).

204, obtaining a plurality of scores based on the above-mentioned signal parameter information for each of the at least one available RAT.

Specifically, a score of each of the at least one available RAT is determined based on the signal parameter information of each of the at least one available RAT, and the plurality of scores are obtained.

In one embodiment, obtaining the plurality of scores based on the signal parameter information for each of the at least one available RAT comprises: the plurality of scores is obtained based on a type of each of the at least one available RAT and signal parameter information for each of the at least one available RAT. Specifically, the plurality of scores may be obtained by determining a score for each RAT based on a type of each RAT in the at least one available RAT and signal parameter information of each RAT. The signal parameter information may be interpreted as information of a signal parameter. The signal parameters may include at least one of signal quality and signal strength.

Specifically, a score for each of the at least one available RAT is determined based on the RATs and signal parameter information for the RATs. For example, the score may be determined based on a first score and a second score, wherein the first score is determined based on the RAT and the second score is determined based on signal parameter information of the RAT. Different RATs correspond to different first scores. The signal parameter information may be classified into three levels, e.g., excellent (or good), general, and bad. The different signal parameter information corresponds to a different second score. The final score may be the sum of the first score and the second score, or a weighted sum of the first score and the second score, without limitation.

As another example, the score of each of the at least one available RAT may also be determined as follows. Each subscription is initially assigned a predefined score based on RAT availability and radio channel conditions. The initial score may be adjusted based on the RATs and signal parameter information of the RATs, respectively, to determine a score for each of the at least one available RAT. Reference may be made to tables 1 and 2, wherein table 1 shows the correspondence between different RATs and different fractional adjustments and table 2 shows the correspondence between different channel conditions and different fractional adjustments. Taking the initial score of 100 as an example, the score corresponding to RAT "5G" and signal parameter information "excellent" may be 100+10+6, i.e., 116.

TABLE 1

RAT	Score of
		5G	+10
4G	+5
		3G	+2.5
2G or no service	+0

TABLE 2

Signal parameter information	Score of
		Excellent (or good)	+6
In general	+3
		Difference of difference	+0

The initial score may also be adjusted based on the RATs and signal parameter information of the RATs to determine a score for each of the at least one available RAT. Reference may be made to table 3, wherein table 3 shows the correspondence between different combinations of RAT and channel conditions and different fractional adjustments. Taking the initial score of 100 as an example, the score corresponding to RAT "5G" and signal parameter information "excellent" may be 100+15, i.e., 115.

TABLE 3 Table 3

Combination of RAT and signal parameter information	Score of
		5G excellent (or good)	+15
5G general	+12.5
		5G difference	+10
4G excellent (or good)	+11
		4G in general	+8
Difference of 4G	+5

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

After determining the score for each RAT based on the signal parameter information for each of the at least one available RAT, the score may be further adjusted or reduced when at least one abnormal event is detected.

206, switching the DDS of the electronic device to a target RAT of a target SIM card based on the scores, wherein the target SIM card is one of the SIM cards.

In an embodiment of the present application, for each of a plurality of SIM cards of an electronic device, signal parameter information of each of at least one available RAT is detected; acquiring a plurality of scores based on the signal parameter information of each of the at least one available RAT; and switching the DDS of the electronic equipment to a target RAT of a target SIM card based on the scores, wherein the target SIM card is one of the SIM cards. Therefore, the DDS of the electronic equipment can be automatically switched without setting in the UI by a user, the operation is convenient, and the switching process of the DDS can be simplified. Further, the DDS handover may be objectively performed based on a score of each of at least one available RAT of each of the plurality of SIM cards, instead of performing the DDS handover based on experience of the user, which may improve accuracy of the DDS handover.

In one embodiment, the above method further comprises the following. Setting a timer after switching the DDS of the electronic device to the target RAT of the target SIM card; and the target RAT residing on the target SIM card until the timer expires.

Because Protocol Service (PS) data may be intermittently unavailable during DDS handoff, a timer is set to avoid frequent DDS handoff between two subscriptions (i.e., two SIM cards or two RATs).

In one embodiment, the above method further comprises the following. After switching the DDS of the electronic device to the target RAT of the target SIM card, before setting the timer, it is detected that the electronic device moves at a moving speed greater than a threshold or that the electronic device is located in an edge area of a cell.

Frequent DDS switching may occur when the electronic device moves at a moving speed greater than a threshold value or the electronic device is located in an edge region of a cell. Thus, upon detecting that the above-mentioned electronic device moves at a movement speed greater than a threshold or that the above-mentioned electronic device is located in an edge region of a cell, a timer is set to avoid frequent DDS handover between two subscriptions (i.e. two SIM cards or two RATs) and further to avoid intermittent PS availability of PS data during DDS handover.

In one embodiment, the above method further comprises the following. After switching the DDS of the electronic equipment to a target RAT of a target SIM card, detecting at least one abnormal event; and updating a score of the target RAT of the SIM card based on the detected at least one anomaly event.

In particular, after determining the score for each of the at least one available RAT based on the RAT and the signal parameter information, the score may be further adjusted and updated based on the detected at least one anomaly event. The updated score can be used as the basis for the next DDS switching.

In one embodiment, the at least one exception event includes at least one of: the protocol service PS data is not available, temporary data is quiesced, and the data throughput of DDS is smaller than that of non-DDS.

Specifically, the at least one abnormal event is classified into at least three types, i.e., PS data is not available, temporary data is quiesced, and DDS has a data throughput smaller than that of non-DDS. The adjustment amplitude of the score of the target RAT of the target SIM card is different for different types of abnormal events. For example, the adjustment amplitude of the score when PS data is detected as not being available is larger than the adjustment amplitude of the score when temporary data is detected as being stopped, and the adjustment amplitude of the score when the temporary data is detected as being stopped is larger than the adjustment amplitude of the score when the data throughput of the DDS is detected as being smaller than the data throughput of the non-DDS. Table 4 may be referenced, table 4 showing the fractional adjustment amplitudes corresponding to different anomaly events.

TABLE 4 Table 4

Abnormal event	Score adjustment
		PS data is not available	Adjusted to 0
Temporary data quiescing	-3
		The data throughput of the DDS is smaller than that of the non-DDS	-5

In one embodiment, the data throughput includes at least one of: data transmission speed, data transmission delay.

In one embodiment, when the at least one abnormal event includes DDS having a data throughput smaller than that of non-DDS, the at least one abnormal event may be detected as follows. Determining a detection interval based on at least one of a connection state of the electronic device and a motion state of the electronic device; and detecting that the data throughput of the DDS is smaller than the data throughput of the non-DDS in any detection interval.

In particular, the electronic device may have a system application (e.g., tools such as ping and iperf) for measuring the data performance (i.e., throughput) of each subscription periodically or in response to events. When the electronic device is in different states, the detection intervals may be different. For example, the detection interval when the electronic device is in the idle mode is different from the detection interval when the electronic device is in the RRC connected mode, and the detection interval when the electronic device is in the static state is also different from the detection interval when the electronic device is in the mobile state.

In one embodiment, the connection state includes an idle mode or an RRC connected mode, and the detection interval when the electronic device is in the idle mode is longer than the detection interval when the electronic device is in the RRC connected mode.

When the electronic device is in idle mode, the detection period (i.e., detection interval) will be longer to avoid frequent wake-up of the electronic device, which may increase the power consumption of the electronic device.

In one embodiment, the motion state includes a stationary state or a moving state, and the detection interval corresponding to the stationary state is longer than the detection interval corresponding to the moving state.

When the electronic device is in a static state, the detection period (i.e., detection interval) will be longer to avoid frequent detection, which may increase the power consumption of the electronic device.

In one embodiment, the PS data unavailability includes at least one of: permanent data quiesce, data volume limit reached, RAT registration denied, internet public data network PDN connection denied, authentication failure, DDS in limited service state.

In one embodiment, the signal parameters include at least one of: signal quality information, signal strength information.

In one embodiment, 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, according to RSRP and RSRQ, the signal parameter information may be classified into three levels, e.g., excellent (or good), general, and poor, as shown in fig. 5, and table 5 shows the correspondence between the level of the signal parameter information and RSRP and RSRQ.

TABLE 5

Signal parameter information	RSRQ(dB)	RSRP(dbM)
			Excellent (or good)	＞-9	＞-85
In general	-12to-9	-103to-111
			Difference of difference	＜-12	＜-111

In one embodiment, the DDS of the electronic device is periodically switched to the target RAT of the target SIM card, or when a request for network data transmission is detected, the DDS of the electronic device is switched to the target RAT of the target SIM card.

306, switching the DDS of the electronic device to a target RAT of a target SIM card based on the plurality of scores, wherein the target SIM card is one of the plurality of SIM cards.

After switching the DDS of the electronic device to the target RAT of the target SIM card, the operations 308 to 312 and 314 to 316 may be performed in parallel. The operations in 308 to 312 aim to avoid frequent DDS handovers between two subscriptions (i.e. two SIM cards or two RATs) and further to avoid intermittent PS availability of PS data during DDS handovers, and the operations in 314 to 316 aim to update the score of the target RAT of the target SIM card according to at least one detected abnormal event.

Therefore, the DDS of the electronic equipment can be automatically switched without setting in the UI by a user, the operation is convenient, and the switching process of the DDS can be simplified. Further, the DDS handover may be objectively performed based on a score of each of at least one available RAT of each of the plurality of SIM cards, instead of performing the DDS handover based on experience of the user, which may improve accuracy of the DDS handover.

Furthermore, since PS data may be intermittently unavailable during DDS handover, a timer is set to avoid frequent DDS handover between two subscriptions (i.e., two SIM cards or two RATs).

In addition, after determining the score for each of the at least one available RAT based on the RAT and signal parameter information, the score may be further adjusted and updated based on the detected at least one anomaly event. The updated score can be used as the basis for the next DDS switching.
