Description

A method and device for dynamically switching between multiple SIM cards in a mobile terminal

technical field

The invention relates to the technical field of mobile communication, in particular to a method and a device for dynamically switching among multiple SIM cards of a mobile terminal.

Background technique

SIM card is the abbreviation of Subscriber Identification Module Card. After inserting the SIM card into the mobile terminal, the user can become a registered user of the network and enjoy various services provided by the network. Most of the mobile phones currently on the market have a single SIM card, but many users have more than one SIM card, and often need to change the SIM card before they can be used, which is quite inconvenient.

With the rapid development of the wireless mobile communication industry, mobile communication products have become a must for people's daily work and life. The number of mobile phone users continues to increase, and the penetration rate is also getting higher and higher, and there are more and more situations where a user has more than two SIM cards at the same time. However, frequent replacement of SIM cards or carrying two mobile phones is very troublesome, so merchants have developed dual-card dual-standby mobile phones. Currently, for mobile phones that support dual-card dual-standby, users need to set a default SIM card in the settings to perform active operations such as calls, text messages, and data networks by default. However, manual switching of the default SIM card in daily use often cannot meet the needs of users . For example: the user works in Shenzhen but lives in Dongguan and has two SIM cards (one in Dongguan and one in Shenzhen). At this time, the user wants to use the Dongguan card first for phone calls, SMS and data network operations when in Dongguan, and vice versa. When you are in Shenzhen, you should give priority to using the Shenzhen card for related operations. However, manual switching in daily use will cause inconvenience to the user, or if it is not changed in time, it will increase the cost of using the mobile phone for the user, which cannot meet the needs of the user.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

A first embodiment of the invention is shown in FIG. 1 .

Fig. 1 is the implementation flow 100 of the method for dynamically switching between multiple SIM cards of a mobile terminal according to the first embodiment of the present invention, and the implementation flow 100 is described in detail as follows:

In step 101, a geographical area corresponding to each SIM card among the plurality of SIM cards is set.

In the first embodiment, there are three methods for setting the geographical area corresponding to each SIM card in the plurality of SIM cards:

The first method is to utilize a third-party map location service. The mobile terminal provides an interface to connect with a third-party map location service, and the user selects the range of the geographical area corresponding to each SIM card on the map, that is, the user opens the map, selects the center and the corresponding geographic area on the map. Radius, determine the geographical area corresponding to each SIM card, and complete the setting of the geographical area corresponding to each SIM card. This approach requires cooperative support from third-party map location services.

The map location service, also known as location service or location-based service, integrates multiple technologies such as GPS positioning, mobile communication, and navigation, and provides comprehensive application services related to spatial location. Such as Baidu's map service, Google's map service, etc.

For example: on the Android platform, the user can use the Android SDK of Baidu Maps to display a map to the user, and the user can select the center and radius of a geographical area corresponding to the SIM card on the map, and determine the location corresponding to the SIM card. You can also directly select the geographical area corresponding to the SIM card through the combination of provinces and cities.

The second method is to build a map in the mobile terminal, and the user sets the center and radius of the geographical area corresponding to each SIM card on the map to complete the setting of the geographical area corresponding to each SIM card . Due to the limited range of use of this map, the built-in map is not very accurate.

The third method is to set a radius with the current location of the mobile terminal as the center, and the range of the circle determined by the center and the radius is the determined geographical area, and the geographical area corresponds to the SIM card corresponding to the current position . This method has certain limitations, and it can only be set when the mobile terminal user is in the geographical area.

Of course, those skilled in the art will easily know that other means can also be used to set the geographic area corresponding to each of the multiple SIM cards.

In step 102, the current location information of the mobile terminal is obtained.

In the first embodiment, the acquisition of the current location information of the mobile terminal is to obtain the latitude and longitude coordinates of the current location of the mobile terminal through positioning technology, and the positioning technology includes one or more of the following: GPS positioning, base station positioning, WiFi positioning, IP positioning, RFID/QR code and other label identification positioning, Bluetooth positioning, sound wave positioning, scene recognition positioning, etc. The user can select an appropriate positioning method according to needs (for example, GPS is a commonly used positioning method, but GPS is not suitable for indoor positioning, so other positioning methods need to be selected indoors), to obtain the latitude and longitude coordinates of the current location of the mobile terminal.

In step 103, according to the current location information of the mobile terminal, determine the current geographical area where the mobile terminal is located, and judge whether the current geographical area corresponds to the currently used SIM card.

In the first embodiment, the latitude and longitude coordinates of the current location of the mobile terminal are obtained through positioning technology, and the latitude and longitude coordinates of the current location are compared with the latitude and longitude coordinates of the geographical area corresponding to each SIM card, and it is judged that the The current location is within the geographical area corresponding to which SIM card. For example: the user has two SIM cards, one in Dongguan and one in Shenzhen, and the SIM card currently used by the user is the SIM card belonging to Dongguan. When the user enters the geographic area where Shenzhen is located, the current location will be Comparing with each of the geographical areas, it can be obtained that the current location is in the geographical area corresponding to the SIM card whose place is Shenzhen, and at the same time, it can be obtained that the current geographical area does not correspond to the currently used SIM card.

In step 104, if the determination is negative, set the SIM card corresponding to the current geographical area among the plurality of SIM cards as the currently used SIM card.

In the first embodiment, in order to save power consumption of the mobile terminal, when it is judged in step 103 that the current geographical area corresponds to the currently used SIM card, there is no need to switch the SIM card. When it is judged in step 103 that the current geographic area is inconsistent with the currently used SIM card, an instruction for switching SIM cards is issued, and the SIM card corresponding to the current geographic area is switched to the currently used SIM card. For example: still the above example, that is, the user has two SIM cards, one in Dongguan and one in Shenzhen, and the SIM card currently used by the user is the SIM card belonging to Dongguan. When the user enters the geographical area where Shenzhen is located, Through comparison and judgment, it can be concluded that the current geographic area is within the geographic area corresponding to the SIM card whose attribution is Shenzhen, that is, the current geographic area is inconsistent with the currently used SIM card. This is an instruction for switching SIM cards, and the attribution is The Shenzhen SIM card is switched to the currently used SIM card. When the user uses it for the first time in Shenzhen, he uses the Shenzhen SIM card.

In a preferred implementation manner of this embodiment, the number of SIM cards in the plurality of SIM cards is 2. At present, dual-card dual-standby mobile terminals are relatively common. When the number of SIM cards is 2, the method of dynamically switching between multiple SIM cards in a mobile terminal is suitable for dual-card dual-standby mobile terminals, and many people work and live in Between the two places, in order to save roaming charges, most of these people have a SIM card for each of the two places.

In a preferred implementation of this embodiment, the geographic area corresponding to each of the multiple SIM cards is defined by a set of latitude and longitude coordinates, and the latitude and longitude coordinates are stored in a database. After the user selects a geographic area on the map, the latitude and longitude coordinates of the geographic area will be returned, and the latitude and longitude coordinates will be stored in the database for subsequent judgment on the current location.

In a preferred implementation of this embodiment, in order to avoid increasing too much power consumption of the mobile terminal, the location information is updated every 30 seconds when the mobile terminal is in the working state, and every 3-5 minutes in the standby state. Update the location information once, or obtain the location information when the system is working without updating the location information. Of course, those skilled in the art will easily know that the time interval for updating location information can be set, as long as it meets the actual meaning.

The method provided by the first embodiment of the present invention allows the user to set the geographical area corresponding to each SIM card according to the needs, use the positioning technology to obtain the current location information, and compare it with the geographical area to determine the current geographical area. The dynamic switching of the SIM card saves the roaming charges caused by the user not having time to manually switch the SIM card, and improves the user experience.
