As shown in fig. 3, in an embodiment, a data switching method is provided, and this embodiment is exemplified by applying the traffic information updating method to the terminal 120 of the application environment in fig. 1. The data switching method specifically comprises the following steps:

step 302: when detecting that the country code MCC of the mobile signal changes, acquiring the identifier of the virtual SIM card in an activated state, wherein the identifier of the virtual SIM card has the MCC to which the virtual SIM card belongs.

Specifically, the terminal may monitor a Mobile Country Code (MCC) through a preset interface, and detect whether the MCC changes, where the MCC may be used to uniquely identify a Country or a region corresponding to the Mobile network. In one embodiment, a terminal may obtain base station information at regular time, and may monitor the base station information through a Telephony Manager interface, where the base station information may include MCC, Mobile Network Code (MNC), Location Area Code (LAC), base station number, and the like, the MNC may be used to identify a Mobile Network to which the terminal belongs, and the LAC may be used to identify different Location areas, and the like. When the terminal detects that the information of the base station changes, it can further determine whether the MCC changes, where the MCC change indicates that the MCC in the current acquired information of the base station is different from the MCC in the last acquired information of the base station.

Further, if the terminal detects that the MCC changes, an identifier of the virtual SIM card currently in an active state is obtained, where the identifier of the virtual SIM card includes an International Mobile Subscriber Identity (IMSI), and the IMSI of the International Mobile Subscriber identity is composed of a Mobile signal country code MCC, a Mobile network Number MNC, and a Mobile Subscriber Identity Number (MSIN). After a user purchases a virtual SIM card meal through the virtual SIM card APP, the server issues IMSI and virtual SIM card meal data to the terminal through the virtual SIM card APP.

Step 304: and judging whether the identifier of the virtual SIM card is matched with the current MCC or not, if so, executing step 302, and if not, executing step 306.

The MCC is a country code number of the mobile subscriber, occupies 3 digits, and is used for identifying the country to which the mobile subscriber belongs, determining whether the MCC in the identifier of the virtual SIM card is the same as the changed MCC detected by the terminal, and if not, indicating that the virtual SIM card currently in an activated state does not meet the use requirement of the current country or region, and needing to switch the virtual SIM card.

In one embodiment, the MCC in china is 460, the MCC in thailand is 520, when the terminal detects that the MCC is changed from 460 to 520, the country to which the mobile network accessed by the terminal belongs is changed from china to thailand, at this time, the terminal detects whether the MCC in the identifier of the virtual SIM card currently in an activated state is 520, and if not, the package data in the virtual SIM card currently cannot access the data network in thailand.

Step 306: acquiring an identifier of an inactivated virtual SIM card, detecting an identifier matched with the current MCC in the identifier of the inactivated virtual SIM card, and selecting the virtual SIM card corresponding to the identifier matched with the current MCC as a target virtual SIM card.

Specifically, a user can purchase a plurality of virtual SIM cards through a virtual SIM card APP, the virtual SIM cards contain virtual SIM card meal data, the virtual SIM cards are stored in a terminal, when the virtual SIM cards in an activated state do not meet the use requirements of the current country or region, identifiers of all the virtual SIM cards which are not activated are obtained, identifiers of the virtual SIM cards with the same MCC as the current MCC in the identifiers of all the virtual SIM cards which are not activated are detected, the corresponding virtual SIM card is selected as a target virtual SIM card according to the detected identifiers of the virtual SIM cards, and the target virtual SIM card represents the virtual SIM card meeting the use requirements of the current country or region.

In one embodiment, a user may purchase a virtual SIM card package in advance through a virtual SIM card APP set on a terminal, and the user may purchase a plurality of different types of virtual SIM card packages according to a schedule, for example, the user may need to go to a plurality of countries or regions in a short period of time and may purchase virtual SIM card packages of different countries respectively. Optionally, the virtual SIM card package may also be a directed traffic package, where the directed traffic package represents a traffic package provided for a specific application to use, and the user may purchase different virtual SIM card packages according to a favorite application, for example, the user may purchase a directed traffic package supporting the use of a chat application and a directed traffic package supporting the use of a video application, respectively.

It is understood that, among the inactive virtual SIM cards, one or at least two virtual SIM cards matching the current MCC may be used. When there are multiple virtual SIM cards matching the current MCC, the terminal may select one of the virtual SIM cards as a target virtual SIM card according to a preset priority, for example, select a virtual SIM card with the largest remaining traffic in a virtual SIM card package as the target virtual SIM card. Optionally, the terminal may also switch the directional traffic package meeting the use condition according to the running application program, so as to meet different use requirements of the user.

Step 308: and closing the virtual SIM card in the activated state at present, and activating the target virtual SIM card.

After the target virtual SIM card is determined, the terminal closes the virtual SIM card in the current activation state, and activates the target virtual SIM card so as to complete the switching process of the virtual SIM card. Further, the terminal stores the flow information of the virtual SIM card in the current activated state into a local database, reads the flow information of the target virtual SIM card from the local database, and respectively stores the flow information of different virtual SIM cards to ensure the accuracy of the flow information statistics of different virtual SIM cards.

In one embodiment, the terminal may display a flow state page through the virtual SIM card APP, the user initiates a flow display request by operating the virtual SIM card APP, and the terminal reads flow information from the local database and returns the flow information to the virtual SIM card APP through the virtual SIM card operating system, so that a page of the virtual SIM card flow state updated in real time appears on the virtual SIM card APP.

Further, when the virtual SIM card currently in the activated state is closed, the terminal stores the traffic information with the identifier of the virtual SIM card into the local database through the virtual SIM card operating system, and when the terminal is switched to the virtual SIM card next time, the traffic information with the identifier of the virtual SIM card can be read from the local database. And the flow information is not lost in the virtual SIM card switching process.

Further, when the target virtual SIM card is activated, the terminal reads the traffic information with the identifier of the target virtual SIM card from the local database through the virtual SIM card operating system, returns the traffic information to the virtual SIM card APP, and displays the traffic state page of the target virtual SIM card through the virtual SIM card APP. The accuracy of the flow information in the virtual SIM card switching process is ensured.

In one embodiment, the traffic information is obtained according to first traffic information recorded in a file system and second traffic information recorded in a cache.

The file system refers to a storage space in a kernel of the terminal for storing the traffic information for a long time. The written traffic information is recorded in the file system. The cache module is a storage space for temporarily storing the traffic information. The cache module stores flow information with preset duration. The traffic information recorded in the cache module is written into the file system at predetermined time intervals.

Further, the process of acquiring the traffic information further includes: acquiring first flow information recorded in a file system; calculating second flow information recorded in the cache module; and obtaining current flow information according to the first flow information and the second flow information and storing the current flow information into a local database. Wherein the first traffic information represents traffic information written to the file system. And summing the first flow information and the second flow information to obtain current flow information, and then outputting the current flow information. The current traffic information is traffic information up to the current time when the traffic query instruction is received.

Further, calculating the second traffic information recorded in the cache further includes: acquiring third flow information from the starting time to the current time; acquiring fourth flow information recorded in the file system from the starting time to the current time; and obtaining the second flow information according to the third flow information and the fourth flow information. The starting-up time refers to the time when the terminal is started up after being restarted. The current time is a time when the traffic statistic request is received, and the third traffic information from the starting time to the current time of the terminal may include traffic information written into the file system and traffic information not written into the file system. And if the fourth traffic information is excluded from the third traffic information, the second traffic information, that is, the traffic information stored in the cache module, can be obtained. In the embodiment, in the process of acquiring the flow information, the flow information in the cache does not need to be written into the file system every time, so that the write operation on the system kernel is reduced, and the consumption of system resources is reduced.

According to the data switching method, when the change of the mobile signal country code MCC is detected, the identification of the virtual SIM card in the activated state is obtained, if the identification of the virtual SIM card is not matched with the current MCC, the identification of the virtual SIM card which is not activated is obtained, the virtual SIM card corresponding to the identification matched with the current MCC is selected as the target virtual SIM card, the virtual SIM card in the activated state is closed, and the target virtual SIM card is activated. By the data switching method, the meal data of the virtual SIM card can be automatically switched according to user requirements, convenience is brought to user use, and user experience is improved.

As shown in fig. 4, in one embodiment, the data switching method further includes the following steps.

Step 402: when the number of the target virtual SIM cards comprises at least two.

When at least two virtual SIM cards are matched with the current MCC and the meal data of the virtual SIM cards in the at least two virtual SIM cards are all directed flow packages, the virtual SIM card meeting the use condition is switched to be used as a target virtual SIM card according to the running application program.

Step 404: and acquiring application program white lists in at least two target virtual SIM cards.

Specifically, the virtual SIM card meal data includes an application white list, in which an application having a network use permission when connected to a data network via virtual SIM card information corresponding to the virtual SIM card meal data may be recorded, and when the terminal purchases the virtual SIM card meal data and acquires the virtual SIM card information, and connects to the data network via the virtual SIM card information for network communication, the application in the corresponding application white list may have the network use permission and may access the data network, and an application not in the application white list may not access the data network. Different applications may be recorded in the application white list included in the different virtual SIM card package data.

Step 406: and acquiring the identifier of the currently running application program, and selecting the virtual SIM card containing the identifier of the application program in the white list of the application program as a target virtual SIM card.

Specifically, the terminal obtains an application program identifier currently running, and selects a directional flow package containing the application program identifier currently running from at least two pieces of virtual SIM card package data, that is, selects a virtual SIM card containing the application program identifier in an application program white list as a target virtual SIM card. For example, the terminal stores a directional traffic package supporting the use of the chat application and a directional traffic package supporting the use of the video application, and when the chat application runs on the terminal, the terminal is switched to the directional traffic package supporting the use of the chat application; when the video application runs on the terminal, switching to the directional flow package supporting the video application to use.

In this embodiment, by obtaining an application program white list and a currently running application program identifier in at least two target virtual SIM cards, a virtual SIM card including the application program identifier in the application program white list is selected as a target virtual SIM card. The meal data of the virtual SIM card can be automatically switched according to the application program operated by the user terminal, convenience is brought to the user, and user experience is improved.

Step 504: transferring the numerical value resource matched with the selected recommended virtual SIM card to a server according to the received selection instruction, and acquiring the virtual SIM card information corresponding to the selected recommended virtual SIM card from the server.

Specifically, a user may purchase a virtual SIM card package through a virtual SIM card APP set on a terminal, a package interface of the virtual SIM card APP may display package data of one or more virtual SIM cards, where the package data of the virtual SIM card may include information about a country or a region to which a data network accessed by the virtual SIM card belongs, a traffic resource amount owned by the virtual SIM card, an effective time, and a numerical resource that needs to be paid, and the traffic resource amount owned by the virtual SIM card refers to a maximum number of bytes that can be consumed when the terminal uses the virtual SIM card for network communication. The user can select the required virtual SIM card package to purchase on the package interface, the terminal can acquire the virtual SIM card information corresponding to the selected virtual SIM card package by transferring corresponding numerical value resources to the server, and the terminal can access the data network through the acquired virtual SIM card information to realize the network communication of the virtual SIM card. The virtual SIM card information may include identification information of the user, authentication information that can be used for accessing a data network, and the like, and may include information such as an international mobile subscriber identity IMSI, a SIM card number, and the like. In one embodiment, the terminal may obtain a corresponding data network through information such as IMSI in the virtual SIM card information, send a network access request to the data network, upload authentication information to the data network, access the data network after passing authentication of the data network, and implement network communication through the virtual SIM card.

If the terminal detects that the MCC changes, a country or a region corresponding to the changed MCC can be determined first, and meal data of the virtual SIM card of the accessed data network belonging to the country or the region can be acquired. For example, when the terminal detects that the MCC changes, and a country corresponding to the changed MCC is japan, the terminal can acquire meal data of a virtual SIM card of which the accessed data network belongs to japan; if the region corresponding to the changed MCC is hong Kong, the virtual SIM card meal data and the like of which the accessed data network belongs to hong Kong can be acquired.
