Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
A Subscriber Identity Module (SIM) card refers to a smart card used by a user terminal, in which user identity identification data, an authentication algorithm, a secret key, and the like are stored, and is used to identify and authenticate the user terminal before the user terminal accesses a communication network. If the user terminal fixedly uses one SIM card, the problems of poor signal, high roaming cost and the like easily occur.
To solve these problems, the cloud SIM card technology has been developed. The cloud SIM card technology is that a large number of SIM cards are stored and managed on a server in a centralized mode, and the SIM cards are shared and used on different devices according to a real-time SIM card allocation method.
However, in the conventional cloud SIM card technology, the SIM card may be called by different devices at a longer distance in a short time, which causes the SIM card normally used to be misjudged as the SIM card abnormally used by the operator, and further causes the SIM card to be disabled, which brings loss to the cloud operator.
For example, one SIM card is just allocated to one user terminal in shenzhen for use, and registers in the shenzhen mobile network; after 1 minute, the card was again assigned to a user terminal in Beijing and registered with the Beijing mobile network. Normally, a user terminal cannot move from shenzhen to beijing in 1 minute, so that an operator misjudges the normally used SIM card as an abnormally used SIM card and deactivates the SIM card.
Based on this, the embodiment of the application provides a method, a device, a server and a computer-readable storage medium for allocating an SIM card, which can solve the technical problem that an operator misjudges a normally used SIM card as an abnormally used SIM card, so that the SIM card is deactivated and loss is brought to a cloud card operator.
In order to explain the technical means of the present application, the following description will be given by way of specific examples.
Fig. 1 shows an interaction diagram of a user terminal and a server provided in an embodiment of the present application. The user terminal 11 may send a SIM card assignment request to the server 13 through the mobile communication network or other network (e.g., WIFI network) 12; after receiving the SIM card allocation request sent by the user terminal 11, the server 13 may allocate an SIM card to the user terminal 11 according to the SIM card allocation method provided in the present application; after the SIM card is successfully assigned, the user terminal 11 may register a network with the operator, and then access the communication network.
Specifically, the user terminal 11 may include a device capable of using a cloud SIM card, and the device may download information of the SIM card allocated by the server and complete authentication of an operator, so as to access the communication network. The server 13 may include a card loading device 131, a database 132, and a SIM card scheduling system 133; the card loading device 131 is a carrier device of an SIM card, and is configured to read information of the SIM card and upload the information of the SIM card to the database 132; the database 132 is used for managing the state of the SIM card, storing basic information of the SIM card, storing package flow charging information, recording historical distribution information of the SIM card, and the like; SIM card scheduling system 133 is used to perform SIM card allocation and scheduling.
Fig. 2 shows a schematic implementation flow diagram of a SIM card allocation method provided in this embodiment of the present application, where the method is applicable to the server shown in fig. 1, and is executed by an SIM card allocation device configured on the server, and is suitable for solving a problem that a normally used SIM card is erroneously determined as an abnormally used SIM card by an operator, so that the SIM card is disabled and a technical problem of loss is brought to a cloud card operator. The SIM card assignment method may include steps 201 to 204.
Step 201, receiving a SIM card allocation request sent by a user terminal.
The SIM card allocation request carries the position information of the user terminal; the location information may include latitude and longitude information of the user terminal or location information of the base station.
Specifically, when the user terminal sends an SIM card allocation request to the server through the base station, if the user terminal supports a Global Positioning System (GPS), the latitude and longitude information of the user terminal may be obtained through the GPS, and the latitude and longitude information of the user terminal is carried in the SIM card allocation request; if the user terminal does not support a Global Positioning System (GPS), the location information of the base station may be obtained during the network searching process of the user terminal, and the location information of the base station is carried in the SIM card allocation request.
The Location information of the base station may include a Mobile Network Code (MNC), a Mobile Country Code (MCC), a Location Area Code (LAC), and a Cell ID of the base station.
In some embodiments of the present application, after receiving the SIM card allocation request sent by the user terminal, the server may include: judging whether the SIM card allocation request carries the position information of the base station or not; if the SIM card allocation request carries the location information of the base station, the latitude and longitude information of the user terminal may be obtained according to the location information of the base station.
It should be noted that the SIM card allocation request may also carry other information such as country information of requesting card allocation, time information of requesting card allocation, and the like, which is not limited in the present application.
Step 202, searching the SIM card status information stored in the database of the server according to the SIM card allocation request, and determining whether the server has an idle card.
In some embodiments of the present application, the database of the server stores SIM card status information, where the SIM card status information indicates a current usage status of the SIM card; for example, when a SIM card is assigned to a user terminal and is not released, the SIM card is a non-idle card in a non-idle state; when the SIM card is not assigned to the user terminal, the SIM card is an idle card in an idle state.
Therefore, in some embodiments of the present application, the server may search SIM card state information stored in the database of the server according to the SIM card allocation request, determine whether the server has an idle card, if the server does not have an idle card, may send information that no card can be divided to the user terminal, and the user terminal may resend the SIM card allocation request after receiving the information, or the server may directly resend the SIM card state information stored in the database of the server until the server has an idle card; if the server has an idle card, the risk coefficient of the idle card can be calculated to complete the SIM card distribution of the user terminal.
Further, in some embodiments of the application, if the SIM card allocation request information carries country information of requesting card allocation, the 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 country information of the request card distribution in the SIM card distribution request, searching the SIM card state information of the SIM card corresponding to the country information of the request card distribution, which is stored in a database of the server, determining whether the server has an idle card corresponding to the country information of the request card distribution, and further distributing the idle card corresponding to the country to different countries.
And 203, if the server has the idle card, acquiring the attribute information of the idle card, and calculating the risk coefficient of the idle card according to the position information of the user terminal and the attribute information of the idle card.
The attribute information of the idle card may include position information corresponding to the last time the idle card is released, and an idle duration of the idle card.
Specifically, as shown in fig. 3, the calculating 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, calculating the card distribution distance corresponding to the idle card according to the position information of the user terminal and the position information corresponding to the idle card when the idle card is released last time.
The position information corresponding to the last time the idle card is released may include longitude and latitude information corresponding to the last time the idle card is released.
Correspondingly, the calculating the card separation distance corresponding to the idle card according to the position information of the user terminal and the position information corresponding to the idle card when the idle card is released last time may include: and calculating the card distribution distance corresponding to the idle card according to the longitude and latitude information of the user terminal and the longitude and latitude information corresponding to the idle card when the idle card is released last time.
In particular, can be prepared by
Figure BDA0002324825990000071
Calculating a card distributing distance corresponding to the idle card; d represents the card separation distance corresponding to the idle card; lung1 and Lat1 represent the longitude and latitude of the user terminal, and Lung2 and Lat2 represent the corresponding longitude and latitude when the idle card is released last time; a represents the difference between the latitude of the user terminal and the corresponding latitude when the idle card is released last time, b represents the difference between the longitude of the user terminal and the corresponding longitude when the idle card is released last time; shormin represents the earth radius.
It should be noted that other methods for calculating the card separation distance corresponding to the idle card are also applicable to the present application, and are not described herein again.
Step 302, determining the ratio of the card separation distance to the idle time of the idle card as the risk coefficient of the idle card.
That is, can pass through
Figure BDA0002324825990000081
Calculating a risk coefficient of an idle card; wherein, R represents the risk coefficient of the idle card, D represents the card separation distance, 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 further include time information corresponding to the last time the idle card is released, and at this time, the idle time of the idle card may be calculated according to the request card distribution time information in the SIM card allocation request and the time information corresponding to the last time the idle card is released.
It should be noted that, the larger the ratio of the card separation distance to the idle time of the idle card, that is, the larger the risk coefficient of the idle card, the shorter the interval time between two uses of the SIM card, the larger the interval distance, therefore, the problem that the SIM card is called by different devices at a longer distance in a short time is more likely to occur when the idle card is allocated to the user terminal; the smaller the ratio of the card separation distance to the idle time of the idle card is, that is, the smaller the risk coefficient of the idle card is, the longer the interval time corresponding to the two uses of the SIM card before and after is, the shorter the interval distance is, and therefore, the problem that the SIM card is called by different devices located at a longer distance in a short time by allocating the idle card to the user terminal is less likely to occur.
And 204, distributing the idle card with the risk coefficient smaller than the first risk threshold value to the user terminal.
The first risk threshold is the maximum risk value which can be accepted by an operator and in which the SIM card is called by different devices at a longer distance in a short time, so that an idle card with a risk coefficient smaller than the first risk threshold is allocated to the user terminal, the SIM card allocated to the user terminal can be the SIM card within the risk range accepted by the operator, and the problem that the normally used SIM card is mistakenly judged as the abnormally used SIM card by the operator is solved.
Since different countries and different operators have different requirements for the risk, in some embodiments of the present application, the server may adjust the first risk threshold according to the needs of different countries or different operators.
In the embodiment of the application, SIM card state information stored in a database of a server is searched according to a received SIM card distribution request sent by a user terminal, whether the server has an idle card or not is determined, and when the server has the idle card, a risk coefficient of the idle card is calculated according to position information of the user terminal and attribute information of the idle card; then, distributing the idle card with the risk coefficient smaller than a first risk threshold value to the user terminal; because the risk coefficient is calculated according to the position information of the user terminal, the position information corresponding to the idle card when the idle card is released last time, and the idle time length of the idle card, the risk coefficient can represent the possibility that the SIM card is called by different devices which are far away in a short time, and the first risk threshold value can be set as the maximum risk value of the risk that the operator can accept that the SIM card is called by different devices which are far away in a short time, so that when the idle card with the risk coefficient smaller than the first risk threshold value is allocated to the user terminal, the SIM card allocated to the user terminal is the SIM card within the risk range which the operator can accept, and the problem that the normally used SIM card is mistakenly judged as the abnormally used SIM card by the operator is solved.
In some embodiments of the present application, among the idle cards with a risk coefficient smaller than the first risk threshold, there may be idle cards with a risk coefficient smaller than the second risk threshold, where the idle cards are idle cards considered by an operator that have an occurrence SIM card with a very low risk of being called by a different device located at a longer distance in a short time, or even 0, and therefore, if there is an idle card with a risk coefficient smaller than the second risk threshold, any idle card with a risk coefficient smaller than the second risk threshold may be directly allocated to the user terminal.
Specifically, if the server includes a plurality of idle cards having risk coefficients smaller than the first risk threshold, as shown in fig. 4, the step 204 may specifically include: step 401 to step 402.
Step 401, it is determined whether there is an idle card with a risk coefficient smaller than a second risk threshold in the idle cards with a risk coefficient smaller than the first risk threshold.
Wherein the second risk threshold is less than the first risk threshold.
Step 402, if there is an idle card with a risk coefficient smaller than a second risk threshold in the idle cards with a risk coefficient smaller than the first risk threshold, allocating any idle card with a risk coefficient smaller than the second risk threshold to the user terminal.
In some embodiments of the present application, since the idle card with the risk coefficient smaller than the second risk threshold is an idle card that is considered by the operator to have a very small risk of being called by a different device at a longer distance in a short time, or even 0, allocating any idle card with the risk coefficient smaller than the second risk threshold to the user terminal can avoid the problem of having a SIM card being called by a different device at a longer distance in a short time. It should be noted that, in the process of allocating the SIM cards, the idle cards with risk coefficients smaller than the second risk threshold have the same and highest allocation priority, and as long as there is an idle card with a risk coefficient smaller than the second risk threshold in the idle cards, any idle card with a risk coefficient smaller than the second risk threshold may be preferentially allocated to the user terminal.
Accordingly, if there is no idle card with a risk coefficient smaller than the second risk threshold from among the idle cards with a risk coefficient smaller than the first risk threshold (that is, the idle card with a risk coefficient smaller than the first risk threshold and larger than the second risk threshold), the idle card with a risk coefficient smaller than the first risk threshold is considered by the operator to be an idle card that the SIM card is considered by the operator to be called by different devices at a longer distance in a short time, but the risk can be accepted by the operator.
Specifically, as shown in fig. 5, after the step 401, the method may further include: and step 403.
Step 403, if there is no idle card with a risk coefficient smaller than the second risk threshold in the idle cards with a risk coefficient smaller than the first risk threshold, sorting the idle cards with a risk coefficient smaller than the first risk threshold, and allocating the idle card with the minimum risk coefficient in the idle cards with a risk coefficient smaller than the first risk threshold to the user terminal.
In some embodiments of the present application, in the process of allocating the SIM card, when there is no idle card with a risk coefficient smaller than the second risk threshold in the idle cards with a risk coefficient smaller than the first risk threshold, the priority of allocation is higher for the idle card with a smaller risk coefficient in the idle cards with a risk coefficient smaller than the first risk threshold, so that the idle cards with a risk coefficient smaller than the first risk threshold may be sorted, and the idle card with the smallest risk coefficient in the idle cards with a risk coefficient smaller than the first risk threshold is allocated to the user terminal.
In the embodiment of the application, by judging whether an idle card with a risk coefficient smaller than a second risk threshold exists in the idle cards with the risk coefficients smaller than the first risk threshold, if an idle card with a risk coefficient smaller than the second risk threshold exists in the idle cards with a risk coefficient smaller than the first risk threshold, any idle card with a risk coefficient smaller than the second risk threshold is allocated to the user terminal; if the idle cards with the risk coefficients smaller than the first risk threshold do not exist in the idle cards with the risk coefficients smaller than the second risk threshold, the idle cards with the risk coefficients smaller than the first risk threshold are sorted, and the idle card with the minimum risk coefficient in the idle cards with the risk coefficients smaller than the first risk threshold is distributed to the user terminal; the SIM card distributed to the user terminal is the SIM card with the lowest possibility of being called by different devices at a longer distance in a short time within the risk range accepted by an operator, and the problem that the normally used SIM card is judged as the abnormally used SIM card by the operator is solved to the maximum extent.
Generally, if there is no idle card with a risk coefficient smaller than the first risk threshold, the server does not have a SIM card that can be allocated to the user terminal, and at this time, the server may send a message that no card can be divided to the user terminal, and end the SIM card allocation. Since during the SIM card assignment process, new idle cards may appear, for example: therefore, in order to improve the success rate of SIM card allocation, in some embodiments of the present application, if there is no idle card with a risk coefficient smaller than the first risk threshold, the server may re-search for an allocable card for SIM card allocation, specifically, as shown in fig. 6, steps 601 to 604 may be included.
Step 601, receiving a SIM card allocation request sent by a user terminal.
The SIM card allocation request carries the position information of the user terminal;
step 602, searching the SIM card status information stored in the database of the server according to the SIM card allocation request, and determining whether the server has an idle card.
Step 603, if the server has an idle card, acquiring attribute information of the idle card, and calculating a risk coefficient of the idle card according to the position information of the user terminal and the attribute information of the idle card.
The attribute information of the idle card comprises corresponding position information when the idle card is released last time and idle time of the idle card.
Step 604, if there is no idle card with a risk coefficient smaller than the first risk threshold in the server, recalculating 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 smaller than the first risk threshold in the server, the risk coefficient may be calculated again for the idle card in the server, and if there is an idle card with a risk coefficient smaller than the first risk threshold, the idle card with a risk coefficient smaller than the first risk threshold is allocated to the user terminal; and if the idle card with the risk coefficient smaller than the first risk threshold does not exist, recalculating the risk coefficient of the idle card in the server until the idle card with the risk coefficient smaller than the first risk threshold appears.
In the embodiment of the application, if the idle card with the risk coefficient smaller than the first risk threshold does not exist in the server, the risk coefficient of the idle card in the server is recalculated until the idle card with the risk coefficient smaller than the first risk threshold appears, so that the success rate of SIM card allocation is improved while the SIM card allocated to the user terminal is the SIM card which is in an idle state and has the lowest possibility of being called by different devices in a short time and in a longer distance within a risk range acceptable by an operator.
It should be noted that, after the idle card with the risk coefficient smaller than the first risk threshold is allocated to the user terminal, the user terminal may release the SIM card, and at this time, the SIM card enters the idle state again. Specifically, as shown in fig. 7, the method includes: steps 701 to 702.
Step 701, obtaining SIM card release information sent by a user terminal.
Step 702, updating the SIM card status information stored in the database of the server according to the SIM card release information.
