For example, a SIM card has just been allocated to a user terminal in Shenzhen and registered with the Shenzhen Mobile Network; 1 minute later, the card is allocated to a user terminal in Beijing and registered with the Beijing Mobile Network. Under normal circumstances, it is impossible for a user terminal to move from Shenzhen to Beijing within 1 minute. Therefore, the operator will misjudge the normally used SIM card as an abnormally used SIM card and disable the SIM card.

Based on this, the embodiments of the present application provide a method, device, server, and computer-readable storage medium for allocating a SIM card, which can solve the problem that a normally used SIM card is misjudged by an operator as an abnormally used SIM card, thereby causing the SIM card to be misused. Deactivation, technical problems that bring losses to cloud card operators.

In order to illustrate the technical solution of the present application, specific embodiments are used for description below.

Fig. 1 shows a schematic diagram of interaction between a user terminal and a server provided in an embodiment of the present application. The user terminal 11 can send a SIM card allocation request to the server 13 through a mobile communication network or other network (for example: WIFI network) 12; after receiving the SIM card allocation request sent by the user terminal 11, the server 13 can use the SIM card provided by this application The card allocation method allocates a SIM card to the user terminal 11; after the SIM card is successfully allocated, the user terminal 11 can register the network with the operator, and then access the communication network.

Specifically, the above-mentioned user terminal 11 may include a device capable of using a cloud SIM card, and the device may download the information of the SIM card allocated by the server and complete the authentication of the operator, and then access the communication network. The aforementioned server 13 may include a card carrying device 131, a database 132, and a SIM card dispatching system 133; wherein the card carrying device 131 is a carrier device of a SIM card, which is used to read SIM card information and upload the SIM card information to the database 132; The database 132 is used to manage the status of the SIM card, store basic information of the SIM card, store package flow billing information, record historical SIM card allocation information, etc.; the SIM card dispatch system 133 is used to allocate and dispatch SIM cards.

Figure 2 shows a schematic diagram of the implementation process of a method for allocating a SIM card provided by an embodiment of the present application. The method can be applied to the server shown in Figure 1 and executed by the SIM card allocating device configured on the server, and is suitable for It is necessary to solve the technical problem that the normal used SIM card is misjudged by the operator as an abnormally used SIM card, which causes the SIM card to be deactivated and brings losses to the cloud card operator. The SIM card allocation method may include step 201 to step 204.

Step 201: Receive a SIM card allocation request sent by a user terminal.

Wherein, the aforementioned SIM card allocation request carries the location information of the user terminal; the location information may include the latitude and longitude information of the user terminal or the location information of the base station.

Specifically, when the user terminal sends a SIM card allocation request to the server through the base station, if the user terminal supports the Global Positioning System (GPS), the user terminal's longitude and latitude information can be obtained through the global positioning system and stored in the SIM card. The allocation request carries the longitude and latitude information of the user terminal; if the user terminal does not support the Global Positioning System (GPS), the location information of the base station can be obtained during the network search of the user terminal, and the SIM card allocation request Carry the location information of the base station.

Wherein, the location information of the above base station may include the mobile device network code (Mobile Network Code, MNC), the mobile country code (Mobile Country Code, MCC), the location area code (Location Area Code, LAC), and the cell code (Cell ID).

In some embodiments of the present application, after the server receives the SIM card allocation request sent by the user terminal, it may include: determining whether the SIM card allocation request carries the location information of the base station; if the SIM card allocation request carries the location information of the base station , The latitude and longitude information of the user terminal can be obtained according to the location information of the base station.

It should be noted that the above-mentioned SIM card allocation request may also carry other information such as the country information of the requested sub-card, and the time information of the requested sub-card, which is not limited in this application.

Step 202: Search the SIM card status information stored in the database of the server according to the SIM card allocation request, and determine whether there is an idle card in the server.

In some implementation manners of the present application, the database of the aforementioned server stores SIM card status information, and the SIM card status information indicates the current use status of the SIM card; for example, when the SIM card is allocated to the user terminal and has not been released, The SIM card is a non-idle card in a non-idle state; when the SIM card is not allocated to a user terminal, the SIM card is an idle card in an idle state.

Therefore, in some embodiments of the present application, the server can look up the SIM card status information stored in the server’s database according to the SIM card allocation request to determine whether the server has an idle card, and if the server does not have an idle card, it can send to the user terminal There is no card-divided information. After receiving the message, the user terminal can resend the SIM card allocation request, or the server can directly re-query the SIM card status information stored in the server’s database until the server has an idle card; if the server exists With an idle card, the risk factor of the idle card can be calculated to complete the allocation of the SIM card to the user terminal.

Further, in some embodiments of the present application, if the above-mentioned SIM card allocation request information carries the requested country information, the above-mentioned searching for the SIM card status information stored in the database of the server according to the SIM card allocation request may further include: According to the requested sub-card country information in the SIM card allocation request, search for the SIM card status information of the SIM card corresponding to the requested sub-card country information stored in the database of the server, and determine whether the server has an idle state corresponding to the requested sub-card country information Card, and then allocate idle cards corresponding to that country to different countries.

Step 203: If there is an idle card in the server, the attribute information of the idle card is obtained, and the risk factor of the idle card is calculated according to the location information of the user terminal and the attribute information of the idle card.

Wherein, the above-mentioned attribute information of the idle card may include the corresponding location information when the idle card was released last time, and the idle time length of the idle card.

Specifically, as shown in FIG. 3, the foregoing calculation of the risk coefficient of the idle card according to the location information of the user terminal and the attribute information of the idle card may include: step 301 to step 302.

Step 301: Calculate the card splitting distance corresponding to the idle card according to the location information of the user terminal and the corresponding location information when the idle card was released last time.

Wherein, the location information corresponding to the last time the idle card was released may include the latitude and longitude information corresponding to the last time the idle card was released.

Correspondingly, the foregoing calculation of the sub-card distance corresponding to the idle card according to the location information of the user terminal and the corresponding location information when the idle card was released last time may include: according to the longitude and latitude information of the user terminal and the corresponding longitude and latitude when the idle card was released last time The information calculates the card distance corresponding to the idle card.

Specifically, you can pass

Calculate the sub-card distance corresponding to the idle card; where D represents the sub-card distance corresponding to the idle card; Lung1, Lat1 represent the longitude and latitude of the user terminal, Lung2, Lat2 represent the corresponding longitude and latitude when the idle card was released last time; a represents the user terminal's corresponding longitude and latitude The difference between the latitude and the corresponding latitude when the idle card was released last time, b represents the difference between the longitude of the user terminal and the corresponding longitude when the idle card was released last time; Shormin represents the radius of the earth.

It should be noted that other methods for calculating the distance of the sub-card corresponding to the idle card are also applicable to this application, and this application will not be repeated here.

Step 302: Determine the ratio of the card splitting distance to the idle time length of the idle card as the risk factor of the idle card.

In other words, you can pass

Calculate the risk coefficient of the idle card; among them, R represents the risk coefficient of the idle card, D represents the distance to the card, and T represents the idle time of the idle card.

In some embodiments of the present application, the attribute information of the idle card may also include time information corresponding to the last time the idle card was released. At this time, the idle time of the idle card may be divided according to the requested time in the SIM card allocation request. The information is calculated from the corresponding time information when the idle card was released last time.

It should be noted that the greater the ratio of the card distance to the idle time of the idle card, that is, the greater the risk factor of the idle card, the shorter the interval between two uses of the SIM card and the larger the interval distance. The allocation of an idle card to a user terminal is more likely to cause the problem that the SIM card is called by different devices at a relatively long distance in a short time; the smaller the ratio of the sub-card distance to the idle time of the idle card, the smaller the risk factor of the idle card, It means that the longer the interval between the two uses of the SIM card, the shorter the distance. Therefore, the allocation of the idle card to the user terminal is less likely to cause the problem that the SIM card is called by different devices at a relatively long distance in a short time. .

Step 204: Allocate idle cards with risk coefficients less than the first risk threshold to the user terminal.

Among them, the first risk threshold is the maximum risk value that the operator can accept when the SIM card is called by different devices at a relatively long distance in a short time. Therefore, an idle card with a risk coefficient less than the first risk threshold is allocated to the user In the terminal, the SIM card allocated to the user terminal can be a SIM card within the risk range acceptable to the operator, thereby solving the problem that the normally used SIM card is misjudged by the operator as an abnormally used SIM card.

Since different countries and different operators have different requirements on this risk, in some embodiments of this application, the server can adjust the first risk threshold according to the needs of different countries or different operators.

In some embodiments of the present application, among the idle cards with a risk coefficient less than the first risk threshold, there may be idle cards with a risk coefficient less than the second risk threshold. These idle cards are considered by the operator to appear that the SIM card is damaged in a short period of time. The risk of calling different devices at a longer distance is very low or even zero. Therefore, if there is an idle card with a risk coefficient less than the second risk threshold, you can directly select any idle card with a risk coefficient less than the second risk threshold. Assigned to the user terminal.

Specifically, if the foregoing server includes multiple idle cards with a risk coefficient less than the first risk threshold, as shown in FIG. 4, the foregoing step 204 may specifically include: step 401 to step 402.

Step 401: Determine whether there is an idle card with a risk coefficient less than a second risk threshold among idle cards with a risk coefficient less than a first risk threshold.

Wherein, the above-mentioned second risk threshold is less than the first risk threshold.

Step 402: If there are idle cards with a risk coefficient less than the second risk threshold among the idle cards with a risk coefficient less than the first risk threshold, assign any idle card with a risk coefficient less than the second risk threshold to the user terminal.

In some embodiments of the present application, because the idle card with a risk coefficient less than the second risk threshold is an idle card that the operator believes that the SIM card will be called by different devices at a relatively long distance in a short period of time, the risk is very small or even zero. Therefore, assigning any idle card with a risk coefficient less than the second risk threshold to the user terminal can avoid the problem that the SIM card is called by different devices at a relatively long distance in a short time. It should be noted that in the process of SIM card allocation, the allocation priority of idle cards with a risk coefficient less than the second risk threshold is the same and the highest. As long as there are idle cards with a risk coefficient less than the second risk threshold, you can Priority is given to assigning any idle card with a risk coefficient less than the second risk threshold to the user terminal.

Correspondingly, if there is no idle card with a risk coefficient less than the second risk threshold among the idle cards with a risk coefficient less than the first risk threshold, the risk coefficient is less than the first risk threshold idle card (that is, the risk coefficient is less than the first risk threshold and greater than the first risk threshold). (2) Idle card with risk threshold) is an idle card considered by the operator that there is a risk that the SIM card will be called by different devices at a relatively long distance in a short time, but the risk can be accepted by the operator. Therefore, the risk can be selected The user terminal assigned to the idle card with the smallest coefficient minimizes the SIM card being called by different devices at a relatively long distance in a short period of time.

Specifically, as shown in FIG. 5, after the above step 401, it may further include: step 403.

Step 403: If there is no idle card with a risk coefficient less than the second risk threshold among the idle cards with a risk coefficient less than the first risk threshold, sort the idle cards with a risk coefficient less than the first risk threshold, and rank the idle cards with a risk coefficient less than the first risk threshold. Among the idle cards with the risk threshold, the idle card with the smallest risk coefficient is allocated to the user terminal.

In some embodiments of the present application, during the process of SIM card allocation, when there is no idle card with a risk coefficient less than the second risk threshold among the idle cards with a risk coefficient less than the first risk threshold, the risk coefficient is less than the first risk. Among the idle cards with a threshold, the smaller the risk coefficient, the higher the priority assigned. Therefore, the idle cards with a risk coefficient less than the first risk threshold can be sorted, and the idle cards with a risk coefficient less than the first risk threshold can be sorted The idle card with the smallest risk factor is allocated to the user terminal.

In this embodiment of the application, it is determined whether there are idle cards with a risk coefficient less than the second risk threshold among idle cards with a risk coefficient less than the first risk threshold, and if there are idle cards with a risk coefficient less than the first risk threshold, there are idle cards with a risk coefficient less than the second risk threshold. For idle cards with a risk threshold, assign any idle card with a risk coefficient less than the second risk threshold to the user terminal; if there is no idle card with a risk coefficient less than the second risk threshold among the idle cards with a risk coefficient less than the first risk threshold, Then sort the idle cards with a risk coefficient less than the first risk threshold, and allocate the idle card with the smallest risk coefficient among the idle cards with a risk coefficient less than the first risk threshold to the user terminal; so that the SIM card allocated to the user terminal is in operation The SIM card with the lowest possibility of being called by different devices at a relatively long distance within a risk range acceptable to the supplier, which minimizes the problem that the normal SIM card is misjudged by the operator as an abnormally used SIM card The problem.

Generally, if there is no idle card with a risk coefficient less than the first risk threshold, the server does not have a SIM card that can be allocated to the user terminal. At this time, the server can send a message that there is no card can be divided to the user terminal, and end the SIM card distribution. In the process of SIM card allocation, a new idle card may appear, such as a SIM card that has just been released. Therefore, in order to improve the success rate of SIM card allocation, in some embodiments of the present application, if there is no risk factor less than For an idle card with the first risk threshold, the server can re-search for a card that can be allocated for SIM card allocation. Specifically, as shown in FIG. 6, step 601 to step 604 can be included.

Step 601: Receive a SIM card allocation request sent by a user terminal.

Wherein, the aforementioned SIM card allocation request carries the location information of the user terminal;

Step 602: Search the SIM card status information stored in the database of the server according to the SIM card allocation request, and determine whether there is an idle card in the server.

In step 603, if there is an idle card in the server, the attribute information of the idle card is obtained, and the risk factor of the idle card is calculated according to the location information of the user terminal and the attribute information of the idle card.

Wherein, the attribute information of the idle card includes the corresponding location information when the idle card was released last time, and the idle time length of the idle card.

Step 604: If there is no idle card with a risk coefficient less than the first risk threshold in the server, recalculate the risk coefficient of the idle card in the server.

In some embodiments of the present application, if there is no idle card with a risk coefficient less than the first risk threshold in the server, the risk coefficient of the idle card in the server can be calculated again, if there is an idle card with a risk coefficient less than the first risk threshold , And allocate an idle card with a risk coefficient less than the first risk threshold to the user terminal; if there is no idle card with a risk coefficient less than the first risk threshold, recalculate the risk coefficient of the idle card in the server until the risk coefficient is less than Idle card with the first risk threshold.

In the embodiment of this application, if there is no idle card with a risk coefficient less than the first risk threshold in the server, the risk coefficient of the idle card in the server is recalculated until an idle card with a risk coefficient less than the first risk threshold appears, so that the The SIM card for the user terminal is in an idle state, and the SIM card with the lowest possibility of being called by different devices at a long distance within a short time within the acceptable risk range of the operator, while improving the allocation of the SIM card Success rate.

It should be noted that after the above-mentioned idle card with a risk coefficient less than the first risk threshold is allocated to the user terminal, the user terminal can release the SIM card. At this time, the SIM card will enter the idle state again. In some embodiments, the server may also receive SIM card release information sent by the user terminal, and update the status of the SIM card. Specifically, as shown in FIG. 7, it includes: step 701 to step 702.

Step 701: Acquire SIM card release information sent by the user terminal.

Step 702: Update the SIM card status information stored in the database of the server according to the SIM card release information.

Wherein, the above-mentioned SIM card release information may include information such as SIM card ownership organization information, user terminal equipment identification information, allocation country information, release time information, and release location information.

Correspondingly, in some embodiments of the present application, updating the SIM card status information stored in the database of the server according to the SIM card release information may include: marking the SIM card corresponding to the release information as an idle card, and according to the The release time information in the SIM card release information determines the idle duration of the idle card, and the location information corresponding to the last time the idle card was released is determined according to the release location information in the SIM card release information.

In the embodiment of the present application, after the user terminal completes the use of the SIM card, the user terminal can release the SIM card. At this time, the SIM card will re-enter the idle state and can be allocated to the user terminal again by the server. Therefore, the user terminal can Send the SIM card release information to the server; after obtaining the SIM card release information sent by the user terminal, the server can update the SIM card status information stored in the server’s database according to the SIM card release information to update the status of the SIM card to facilitate this The next allocation of the SIM card.
