Fig. 2 is a flowchart illustrating a method for determining a primary SIM card of a mobile terminal according to an embodiment of the present disclosure, where the method in fig. 2 can be executed by the mobile terminal 100 in fig. 1, particularly by a program module configured in the mobile terminal 100, and can also be executed by a cloud server, as shown in fig. 2, the method at least includes the following steps:

step S201, acquiring first frequency band information of a frequency band supported by a mobile terminal; each mobile terminal (e.g., mobile phone) has a plurality of frequency bands that can be supported by the mobile terminal before the mobile terminal leaves the factory.

Step S202, second frequency band information of frequency bands supported by operators in the target geographic position is obtained; the target geographical position information may be current geographical position information acquired by a GPS positioning module, or destination geographical position information input by a user.

Step S203, determining a target primary SIM card applicable to the mobile terminal at the target geographic location according to the first frequency band information and the second frequency band information.

In the case that the target geographic location information is the destination geographic location information input by the user, the user may obtain the SIM card suitable for the mobile terminal in the country or the region through the steps S201 to S203 before going to a certain country or region, so that the user can purchase the suitable SIM card in advance before going to the destination, and thus the user can be accurately guided to purchase the SIM card having the optimal signal quality when the mobile terminal is at the target geographic location, so that the user can purchase the SIM card suitable for the mobile terminal at the specific geographic location in a targeted manner.

It should be noted that, there is no strict sequence between steps S201 and S202, and the embodiment of the present application is not limited. In addition, the steps S201 to S203 may be executed on the local mobile terminal, or may be executed in the cloud server, and when the cloud server is executed, the cloud server receives the primary SIM card query request sent by the mobile terminal, and then determines the target primary SIM card applicable to the mobile terminal at the target geographic location, and then sends the target primary SIM card determination result to the corresponding mobile terminal.

In the embodiment of the application, the main SIM card with better signal quality at the target geographic position of the mobile terminal can be automatically determined by combining the frequency band which can be supported by the mobile terminal and the frequency band which can be supported by each operator at the target geographic position, so that the preferable main SIM card can be intelligently recommended for a user, the mobile terminal can have better signal quality when being used at the target geographic position, the communication quality between the mobile terminal and a base station is ensured, and the user experience is further improved.

As shown in fig. 3, the step S202 of obtaining the second frequency band information of the frequency band supported by each operator in the target geographic location specifically includes:

step S2021, determining the country or region to which the target geographical position belongs; for example, when the target geographic location is Beijing, the country or region to which it belongs is China.

Step S2022, searching the frequency band supported by each operator corresponding to the determined country or region according to the corresponding relation between the pre-stored country or region and the frequency band supported by each operator; specifically, in the corresponding relationship, the frequency bands supported by each operator in china are searched.

Step S2023, determining the found frequency bands supported by the operators as the second frequency band information.

Specifically, considering that there is a certain difference between the frequency bands of the operators supported by different provinces and cities belonging to one country, the country or region can be subdivided according to actual requirements, and the corresponding relationship can include mapping relationships between the frequency bands supported by the provinces and cities, the counties and the operators, so that the determined target main SIM card is more targeted, and the accuracy of the determined target main SIM card is improved.

As shown in fig. 4, the step S203 determines, according to the first frequency band information and the second frequency band information, a target primary SIM card applicable to the mobile terminal at the target geographic location, and specifically includes:

step S2031, calculating the frequency band matching degree of the mobile terminal and each operator at the target geographic position according to the first frequency band information and the second frequency band information;

and step S2032, determining a target main SIM card applicable to the mobile terminal at the target geographic position according to the matching degree of each frequency band.

In the embodiment of the application, a mode of comparing the frequency band matching degrees is adopted to determine the target main SIM card applicable to a certain mobile terminal at a specific target geographic position, and the higher the frequency band matching degree is, the more communication channels selectable by the mobile terminal at the target geographic position are, so that the mobile terminal can be ensured to have better signal quality when being used at the target geographic position. The method is simple, does not need a complex calculation mode, and can quickly provide practical instructive opinions for the user.

Specifically, the step S2031 of calculating, according to the first frequency band information and the second frequency band information, a frequency band matching degree between the mobile terminal and each operator at the target geographic location specifically includes:

step one, respectively determining the number of shared frequency bands between a mobile terminal and each operator of a target geographic position according to the first frequency band information and the second frequency band information;

and step two, aiming at each operator, determining the ratio of the number of the common frequency bands corresponding to the operator to the number of the frequency bands supported by the operator as the frequency band matching degree of the mobile terminal and the operator.

For example, the frequency bands supported by the mobile terminal (e.g., a mobile phone) are: b1 and B2, that is, the first frequency band information, are frequency bands supported by each operator at the target geographic location, that is, the second frequency band information, which is queried based on the correspondence relationship in table 1 below, specifically:

TABLE 1

Name of operator	Support frequency band (target geographical position)
		China Mobile	B1、B2、B4
China Unicom	B1、B2、B3、B5
		China telecom	B2、B3

Therefore, the number of the common frequency bands between the mobile terminal and the china mobile, the china unicom and the china telecom is respectively as follows: 2. 2, 1, therefore, the frequency band matching degree between the mobile terminal and China Mobile, China Unicom, China telecom is: 66.7%, 50% and 50%.

Further, in order to meet actual requirements of different users, the SIM card provided by the operator with the highest frequency band matching degree may be directly used as the target master SIM card, or the SIM cards provided by the operators with a plurality of frequency band matching degrees meeting preset conditions may be selected as the target master SIM card, so that the user may select a satisfactory SIM card from the operators by combining their own actual conditions, which may meet the actual requirements of different users and improve user experience.

In a first implementation manner, as shown in fig. 5, in step S2032, the determining, according to the matching degree of each frequency band, a target primary SIM card applicable to the mobile terminal at the target geographic location specifically includes:

Still taking the example in table 1 as an example, at this time, the SIM card provided by china mobile is used as the target main SIM card applicable to the mobile terminal at the target geographic location.

In the embodiment of the application, in the process of determining the target main SIM card applicable to the mobile terminal at the target geographic location, the SIM card provided by the operator with the highest frequency band matching degree is directly used as the target main SIM card, and in the case of using the target main SIM card as the mobile terminal main card, the user will enjoy the best communication quality by using the mobile terminal at the target geographic location.

In a second implementation manner, as shown in fig. 6, in step S2032, the determining, according to the matching degree of each frequency band, a target primary SIM card applicable to the mobile terminal at the target geographic location specifically includes:

step S20322, determining SIM cards provided by a plurality of operators with frequency band matching degrees meeting preset conditions as alternative main SIM cards of the mobile terminal; the preset condition may be that the frequency band matching degree is greater than or equal to a preset threshold, for example, the frequency band matching degree is greater than or equal to 50%.

Step S20323, displaying a plurality of standby main SIM cards according to the sequence of the frequency band matching degree from high to low; specifically, taking the example in table 1 as an example, a dialog box may pop up on the display screen of the mobile terminal to prompt the user that the priority order of the target primary SIM card applicable to the mobile terminal in the target geographic location is china mobile, china unicom, and china telecom.

Step S20324, acquiring a selection operation instruction for the multiple candidate main SIM cards by the user, and determining the candidate main SIM card corresponding to the selection operation instruction as the target main SIM card of the mobile terminal, where, in case that the user clicks and selects china unicom, the SIM card provided by china unicom is determined as the target main SIM card of the mobile terminal.

In the embodiment of the application, the SIM cards provided by operators with the frequency band matching degrees meeting the preset conditions are selected as the target main SIM card, so that a user can select one satisfied SIM card from the target main SIM card by combining the actual conditions of the user, the selection flexibility of the main card of the mobile terminal is improved, and the user experience degree is improved.

Based on the two implementation manners of determining the target main SIM card applicable to the target geographic location, in specific implementation, which manner to use may be determined according to the setting parameters of the mobile terminal, and two options of the determination manner of the target main SIM card are provided in the system setting: a first mode (automatic determination) and a second mode (free selection), based on which the method further comprises:

receiving target SIM card determination mode selection information of a user, wherein the selection information carries a target SIM card determination mode option type;

if it is determined that the first mode is carried in the mode selection information, step S2032 is performed to determine, according to the matching degree of each frequency band, a target primary SIM card applicable to the mobile terminal at the target geographic location, and specifically includes:

step S20321, determine the SIM card provided by the operator with the highest frequency band matching degree as the target primary SIM card applicable to the mobile terminal at the target geographic location.

If it is determined that the second mode is carried in the mode selection information, step S2032 is performed to determine, according to the matching degree of each frequency band, a target primary SIM card applicable to the mobile terminal at the target geographic location, and specifically includes:

step S20322, determining the SIM cards provided by multiple operators whose frequency band matching degrees meet the preset conditions as the alternative primary SIM cards of the mobile terminal.

Step S20324, acquiring a selection operation instruction for the multiple candidate primary SIM cards by the user, and determining the candidate primary SIM card corresponding to the selection operation instruction as the target primary SIM card of the mobile terminal.

Further, in the embodiment of the present application, after the target primary SIM card is determined, for a situation that the target primary SIM card is already set in the mobile terminal, the mobile terminal primary card may be automatically switched to the target primary SIM card, or corresponding prompt information may be displayed for the user; for the situation that the target primary SIM card is not set in the mobile terminal, corresponding prompt information may be displayed for the user, or an SIM card with the highest frequency band matching degree may be selected from the set SIM cards as the primary card of the mobile terminal, based on this, as shown in fig. 7, after determining the target primary SIM card applicable to the mobile terminal in the target geographic location according to the frequency band matching degrees in step S2032, the method further includes:

step S204, judging whether the mobile terminal is provided with the determined target main SIM card;

if yes, executing step S205, and judging whether the current main SIM card of the mobile terminal is consistent with the determined target main SIM card;

if not, executing step S206 to set the determined target primary SIM card as the primary SIM card of the mobile terminal; or generating prompt information for switching the main SIM card of the mobile terminal; therefore, the method is helpful for guiding the user to quickly determine the main card with better communication quality at the target geographic position from the plurality of SIM cards arranged in the mobile terminal, thereby ensuring the communication quality of the mobile terminal and avoiding the phenomena of network disconnection and weak signals.

If not, executing step S207 to generate prompt information for suggesting the allocation of the determined target main SIM card; and/or selecting the SIM card provided by the operator with the highest frequency band matching degree from the plurality of set SIM cards to set as the main SIM card of the mobile terminal. Therefore, under the condition that the determined target main SIM card is not arranged in the mobile terminal, guiding suggestions are provided for the user, so that the user can purchase the target main SIM card applicable to the mobile terminal at the target geographic position.

In addition, considering that certain differences exist in the frequency bands supported by the SIM cards provided by the same operator, in order to improve the accuracy of the setting of the main card of the mobile terminal, if the mobile terminal is already provided with a target main SIM card and the current main SIM card is not the target main SIM card, it is determined whether the frequency band matching degree between the frequency band supported by the current main SIM card and the common frequency band corresponding to the target main SIM card meets a preset condition, if so, the operation is stopped, and if not, prompt information suggesting to allocate the determined target main SIM card supporting the preset frequency band is generated;

meanwhile, if the mobile terminal is provided with the target main SIM card and the current main SIM card is not the target main SIM card, whether the frequency band matching degree between the frequency band supported by the set SIM card and the common frequency band corresponding to the target main SIM card meets a preset condition or not is judged, if yes, step S206 is executed, and if not, prompt information for suggesting the determined target main SIM card supporting the preset frequency band is prepared. .

Further, considering that there may be a situation that a certain supported frequency band is unavailable due to a certain hardware abnormality or a software abnormality in the mobile terminal, if the first frequency band information includes the unavailable supported frequency band, at this time, the accuracy of the determined target master SIM card is reduced, and based on this, as shown in fig. 8, the step S201 obtains the first frequency band information of the frequency band supported by the mobile terminal, specifically includes:

step S2011, determining whether the mobile terminal meets a frequency band transmitting power detection condition;

if yes, executing step S2012, and performing transmission power detection on each supported frequency band of the mobile terminal;

if so, determining that the mobile terminal meets the frequency band transmission power detection condition;

if not, determining that the mobile terminal does not meet the frequency band transmission power detection condition.

In the embodiment of the application, the transmitting power of the supporting frequency band is detected by adding, and in the process of determining the target main SIM card of the mobile terminal, the supporting frequency band with the transmitting power not meeting the preset requirement is excluded, so that the accuracy of the determined target main SIM card is improved, and the user experience degree is further improved.
