Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. On the basis of the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without any creative effort belong to the protection scope of the present application.
In a first aspect, an embodiment of the present application provides a card number switching method, which is executed by a card number switching device, where the card number switching device includes a subscriber identity module SIM card, where the SIM card is provided with at least two card numbers, as shown in fig. 1, and the method includes:
It should be understood that the resources of the Mobile Country Code (MCC) are uniformly allocated and managed by the International Telecommunications Union (ITU), and uniquely identify the Country to which the Mobile subscriber belongs, which is 3 digits, for example, the MCC information of china is 460. The SIM card is provided with at least two card numbers, and the SIM card can be a one-card double-number SIM card or a one-card multi-number SIM card. The SIM card related to the embodiment of the application can be applied to terminals of the Internet of things, including but not limited to mobile phones, vehicles operated across the country and shared bicycles.
Specifically, if the MCC information is identified from the first LAI information, the MCC information is compared with MCC information in an MCC information table to determine a country to which the card number switching device is located, and the currently-operating card number of the SIM card is set as the card number corresponding to the MCC information, where the card number corresponding to the MCC information is the card number of the country to which the card number switching device is located.
The first target card number can be a card number of China or a card number of other countries. Identifying the case where the MCC information is not available from the first LAI information includes: the first LAI information of the position of the card number switching device is not acquired successfully; the first LAI information of the position of the card number switching device is successfully acquired, but the MCC information cannot be identified.
As will be described in further detail below with reference to step 103, by way of example, when the range of the SIM card user activity is british and french, a "one-card-two-number" SIM card may be handled, where one card number is attributed to british and the other card number is france, and in a case where the card number currently operated by the SIM card is a first target card number, for example, a british card number, if the MCC information of the mobile country code cannot be identified from the first LAI information, the british card number is switched to a card number other than the first target card number, that is, a france card number. Step 103 can avoid the situation that the mobile phone loses signals without switching numbers under an abnormal condition.
In the embodiment of the application, the LAI information of the first location area identification code of the location of the card number switching device is obtained, the MCC information of the mobile country code is identified from the first LAI information, the card number of the current work of the SIM card is set to be the card number corresponding to the MCC information, if the MCC information of the mobile country code cannot be identified, the card number of the current work of the SIM card is switched to another card number which does not work, the card number is automatically switched according to the MCC information, a user does not need to manually replace the SIM card when the user leaves/enters the border, and the problem that the user is inconvenient to replace the SIM card when the user leaves/enters the border in the prior art is solved.
In addition, some working people who need to go out of two countries frequently transact one door number in each country, and use different door numbers in different countries to save international roaming cost. The method provided by the embodiment of the application can be applied to the SIM card with one card and two numbers. The one-card-two-number service is that two digital mobile phone numbers are opened on one SIM card, and a user can select any one of the numbers to carry out conversation by switching through the menu operation of the mobile phone, so that the communication requirements of the user for using different numbers at different time and different places are met, and a personalized communication mode is provided for the user. By applying the method of the embodiment of the application, the number of the user using one card with two or more numbers is automatically switched according to the geographical position, so that the user can use the mobile phone more conveniently, and the communication charge is saved.
Optionally, the method further includes:
receiving an instruction input by a user;
and switching the card number of the SIM card which works currently under the condition that the input instruction is matched with a preset instruction rule.
Specifically, the user input instruction may be input through a key, and the preset instruction rule may be that the user presses the key to switch the card number of the SIM card currently operating to another card number. By additionally arranging the function of switching the working card number of the SIM card through an instruction, the situation that the SIM card is not switched to cause user communication interruption and cannot normally use the SIM card under the abnormal condition can be avoided. The specific implementation mode can be as follows: the card number switching device comprises a Long Term Evolution (LTE) module, and instructions are integrated in the LTE module: 00a4000C02DF20, 00a4000C02EFFC, 00D600000101, the user manually switches the card number by pressing a button.
Optionally, if the mobile country code MCC information is identified from the first LAI information, setting the card number of the SIM card currently operating as the card number corresponding to the MCC information, including:
under the condition that the currently working card number of the SIM card is a second target card number, if MCC information is identified from the first LAI information and the MCC information corresponding to the third target card number is detected within a first preset time length, switching the currently working card number of the SIM card from the second target card number to the third target card number;
wherein the second target card number and the third target card number are different ones of the at least two card numbers.
It should be understood that the second target card number may be a card number of China, or a card number of another country, and the third target card number may be a card number of China, or a card number of another country, where the second target card number is different from the third target card number. The first preset time period may be set according to actual needs, for example, the first preset time period may be 5 minutes.
The following further describes the embodiments of the present application by way of example. When the user activity range of the SIM card is both China and French, the SIM card with one card and two numbers can be handled, wherein the attribution of one card number is China and the attribution of the other card number is France. And under the condition that the currently working card number of the SIM card is a second target card number, such as China, if MCC information is identified from the first LAI information and the MCC information corresponding to a third target card number, such as France, is detected within a first preset time period, switching the currently working card number of the SIM card from the card number with the country of attachment being China to the card number with the country of attachment being France. By additionally arranging the limit of the first preset time length, the situation that the signal of the user is not good due to frequent switching of the card number when the user moves in the border of China and the French can be avoided. The specific implementation mode can be as follows: the card number switching device also comprises an SIM module, the SIM module is connected with the LTE module, and a time parameter is added in the switching logic of the SIM module. And when the MCC information acquired by the network detection unit of the SIM module is consistent with the MCC information corresponding to the third target card number and the MCC information is the MCC information corresponding to the third target card number in the first preset time length, the currently working card number of the SIM card is the third target card number, otherwise, the SIM card is not switched, and the currently working card number of the SIM card is still the second target card number.
Optionally, the obtaining the first location area identity LAI information of the location of the card number switching device includes:
acquiring first LAI information of the position of the card number switching device according to a preset time interval;
if the mobile country code MCC information cannot be identified from the first LAI information, switching the card number of the SIM card currently working from the first target card number to a card number other than the first target card number of the at least two card numbers, including:
and if the mobile country code MCC information cannot be identified from the acquired first LAI information within a second preset time length, switching the card number of the SIM card currently working from the first target card number to a card number other than the first target card number in the at least two card numbers.
It should be understood that the preset time interval can be set according to actual needs, and can be set to 5s, and the second preset time period can also be set according to actual needs, such as 3 s. The specific implementation manner may be that the card number switching device further includes a counter, the counter counts once every 0.3s, and if the mobile country code MCC information cannot be identified for 10 consecutive times, the card number currently working on the SIM card is switched from the first target card number to a card number other than the first target card number of the at least two card numbers. And if the mobile country code MCC information can not be identified after switching, switching the card number of the SIM card which works currently into the card number except for the currently working card number of the at least two card numbers. By additionally arranging the second preset time length and switching the card number according to the second preset time length, the situation that the SIM card cannot be switched to the number and the user loses signals and cannot use the SIM card due to the fact that MCC information cannot be identified under the abnormal condition can be avoided.
