Background

With the warming of traffic competition and the massive popularization of the full-network dual-card terminal, the market competition in the telecommunication industry evolves from competition for "users" to competition for "card slots".

Hereinafter, the related terms and techniques referred to in the present application will be explained.

1) Double-card slot mobile phone

The Dual card slot mobile phone may be a Dual SIM Dual Standby (DSDS) mobile phone, which means that the mobile phone can be inserted with two SIM Identity Modules (SIM) cards and can be in Standby mode at the same time, and the mobile phone can connect with the same or different network of the operator through the two SIM cards and interact with the network provided by the operator to generate service traffic.

2) Home network and different network

The network uses the communication network provided by the operator for the SIM card to generate communication service and communicate with other equipment; the different network is a communication network which is not provided by the operator and is used by the SIM card, and generates communication service to communicate with other equipment.

3) Main card and auxiliary card

Under normal circumstances, a user of a dual-card dual-standby mobile phone only uses one SIM to perform traffic consumption services, and performs other non-traffic consumption services (such as receiving and making calls, receiving short messages, etc.); for a user of the dual-card dual-standby mobile phone, the SIM card mainly performing traffic consumption services is called a primary card, and the SIM card mainly performing other non-traffic consumption services (such as making and receiving calls, receiving short messages, etc.) is called a secondary card; for example, a user of a dual-card dual-standby mobile phone may use SIMa as a SIM card for receiving a call and SIMb as a SIM card for traffic consumption, where SIMa is a secondary card and SIMb is a primary card.

4) Cell

A cell, which may also be referred to as a cell, refers to an area covered by one or a part of a base station (sector antenna) in a cellular mobile communication system, in which a terminal covered in this area can reliably communicate with the base station through a radio channel.

5) Double card state

The dual card state, that is, the use state of the dual card slot terminal user to two SIM cards: comprises the following steps of;

this net double cassette: even if two SIM cards provided by the same operator are used, it is not distinguished which of the two cards is the primary card and which is the secondary card.

The double-card main card: namely, the SIM card mainly used for carrying out the traffic consumption service is used in the two SIM cards provided by the operator.

Double-card auxiliary card: namely, the SIM card mainly used for non-flow consumption service is used in the two SIM cards provided by the operator.

The main card of the network and the auxiliary card of the network: i.e. two SIM cards provided by the operator, one as the primary card and the other as the secondary card.

The main card of the different network is a main card of the local network and a secondary card of the different network: it can also be called as auxiliary card of home network for short, i.e. one SIM card provided by the operator and one SIM card provided by other operators are used, and the SIM card provided by the operator is used as the auxiliary card.

The different network auxiliary card is a network main card: it can also be called home network main card, i.e. uses a SIM card provided by the operator, and uses it as main card; and the other SIM card uses the SIM card provided in the other operation.

6) XDR call ticket data

The XDR (xdetail record, XDR) ticket data refers to a full-quantity detail list acquired in a Deep Packet Inspection (Deep Packet Inspection DPI) signaling acquisition system. The XDR call list data is divided into a signaling Detail list (Signal Detail Record, SDR) and a Flow Detail list (FDR) aiming at the signaling part, and the XDR is a general name of the SDR and the FDR.

DPI is an improved technique over SPI (shallow packet inspection). The SPI analyzes only the L2-L4 headers of the IP packet data, and the main contents generally include a source address, a source port, a destination address, a destination port, a protocol type, and the like; besides the contents of L2-L4, the DPI also adds the analysis of L7 (application layer), can analyze the contents in the payload of the IP data packet more deeply, and can perform classification and analysis according to different characteristics of specific application data (such as data downloading, voice, video, instant messaging, shopping payment, game entertainment and the like) of a user, thereby further performing deep internet data mining.

With the popularization of mobile communication, more and more people own more than two telephone cards, some of the people own the telephone cards belonging to different operators, and some of the people select the double-card-slot terminal for convenience. In a dual card slot terminal, for example, a dual card slot mobile phone terminal, two card slots are provided to simultaneously hold two cards, and both cards are in a standby state and interact with a communication network independently. The two cards may belong to the same operator or to two different operators. For an operator, accurately identifying two cards in two card slots of a dual-card-slot terminal and states of the two cards is a basis for managing the dual-card-slot terminal of the current network, developing target customers and troubleshooting the dual-card-slot terminal, however, the network of the operator can only identify the card registered in the communication network of the operator and cannot know whether a card is inserted into the other card slot of the dual-card-slot terminal and the state of the other card. For operators, the method is used for accurately identifying the states of two cards in two card slots of a double-card-slot terminal, and is a basis for business expansion, deep ploughing of customer stickiness and accurate positioning of customer requirements.

In the prior art, whether two SIM cards belong to the same terminal is mostly judged by judging whether communication data corresponding to IMEI satisfies space-time synchronization (whether time of communication data generation is synchronous or not, and whether update position is synchronous or not), and a main card and an auxiliary card are distinguished by the size of traffic generated by the SIM cards; in the prior art, only LAC codes are used when determining whether the updated positions are synchronous, however, one LAC code covers a wide range of positions and covers a large number of terminals, which makes it easy to misjudge whether the updated positions are synchronous. For example, when two terminals of the same manufacturer and the same model are simultaneously updated, the TAC codes of the devices are the same, and the portions of the IMEI codes representing the models of the terminals are also the same, so that the SIM cards on the two terminals are misjudged. In the prior art, the different-network main card and the different-network auxiliary card are distinguished only by the flow consumption of the SIM card, the WIFI use condition of a user is not considered, and the judgment on the card state is rough; therefore, the success rate and the accuracy of judging the double-card state in the prior art are low, the efficiency of subsequent operators in marketing to users is affected, and the difficulty and the cost of market expansion of the operators are increased.

Based on this, the embodiment of the application provides a method for identifying the double-card state of a double-card-slot terminal, in the method, the double-card state of the terminal is distinguished through service data information generated during terminal communication and/or a cell number corresponding to a cell experienced; compare in using LAC to judge, this application judges the double cassette state from more meticulous dimension, can make the double cassette state that obtains more accurate, can improve the success rate of double cassette state discernment. Meanwhile, the scheme also uses the distribution index (such as the cell experienced by the terminal) to judge whether the user uses WIFI or not, so that the double-card state can be more accurately distinguished. The operator can more accurately position the user demand and push more appropriate marketing promotion activities for the user based on more accurate double-card state.

Hereinafter, the technical solutions provided in the embodiments of the present application will be described with reference to the drawings.

As shown in fig. 2, a schematic diagram of a method for identifying a dual card status of a dual card slot terminal provided in an embodiment of the present application includes the following steps:

s100, obtaining X detailed record XDR call ticket data of a plurality of terminals in a preset time period.

The plurality of terminals are terminals adopting first mobile internet communication, namely the plurality of terminals establish communication connection with the first mobile internet, communicate by using the first mobile internet and generate communication data; it is to be understood that the first mobile internet described in the present embodiment may be a network provided by a certain provider (operator) that provides network services.

The XDR ticket data comprises: IMEIs corresponding to a plurality of terminals and communication data corresponding to each IMEI; the communication data comprises at least one of service data information and cell numbers;

the communication data corresponding to the IMEI can be understood as communication data generated when the dual card slot terminal uses the IMEI to perform communication interaction with the first internet; for example, when the IMEIa of a certain dual card slot terminal performs initial registration, the generated registration start time (starttime), registration end time (endtime), and the like are all communication data corresponding to the IMEIa.

The International Mobile Equipment Identity (IMEI), which is commonly called a Mobile phone serial number and a Mobile phone "serial number," is used to identify Mobile communication Equipment such as each independent Mobile phone in a Mobile phone network, and is equivalent to an Identity card of a Mobile phone. The serial number has 15-17 digits, and the first 8 digits (6 digits in the early stage) are a model approval number, also called Type Allocation Code (TAC), which is a Code for distinguishing the brand and model of the mobile phone. Next, 2 bits are the last assembly number (present only in earlier models) representing the final assembly code. The last 6 bits (SNR) are the string number, representing the production sequence number. In a dual card slot terminal, two SIM cards each correspond to an IMEI, and since the two SIMs are in one terminal, the TAC of the two SIM cards is also the same.

In a possible implementation manner of step S100 in the embodiment of the present application, under the condition that the 4G and 5G communication systems are adopted, the communication data in the XDR ticket data may include XDR data of a 4G signaling plane and a user plane, and XDR data of a 5G signaling plane and a user plane.

The embodiment of the application can use the S1-MME of 4G, the N1N2 of 5G, the S1-U of 4G and the N3 interface of 5G to collect the communication data of the 4G signaling plane and the user plane and the communication data of the 5G signaling plane and the user plane through the DPI technology. Communication data of the S1-MME interface of 4G and the N1, N2 interfaces of 5G are signaling plane data or communication data called signaling plane, and communication data of the S1-U interfaces of 4G and the N3 interfaces of 5G are user plane data or communication data called user plane.

The communication data of the 4G signaling plane and the user plane comprises: s1mme _ Attach, s1mme _ Detach, s1mme _ TAU (regional location update), s1mme _ Handover; the communication data of the 5G signaling plane and the user plane comprises: n1n2_ registration, n1n2_ De-registration, and n1n2_ Handover.

S1-MME of 4G, N1N2 of 5G refer to the interface between the radio access network and the core network in the 4G and 5G wireless communication networks, respectively. The S1 interface is a communication interface between an LTE eNodeB (base station) and an EPC (packet core network), and is a boundary between a radio access network and a core network divided by an LTE system. According to the difference of the bearing function and the control function of the S1 interface, the method is divided into S1-MME and S1-U, wherein the S1-MME is a signaling interface used for a control plane, and the S1-U is a data interface used for a user plane.

N1 is an interface between the UE (terminal) and an access and mobility management function (AMF) unit of a 5G core (5G core,5 GC), and N2 is an interface between the RAN (radio access network) and the AMF unit of the 5 GC. N1 is an interface of a logical concept, no physical interface exists, and N2 is a physical interface. The N1 interface actually implements communication between the UE and the AMF by signaling of the N2 interface after the UE interfaces with the RAN. The N2 interface is mainly related to connection management, UE context and PDU session management and UE mobility management. Further non-access stratum (NAS) signaling between the UE and the AMF is transported over the N2 interface, wherein the NAS signaling includes information about access control, authentication and authorization, and session management procedures. The network equipment can realize the issue of services such as SMS and service strategies to the UE through the N1 interface, and can also acquire the position information from the UE.

It is understood that the preset time period in S100 may be a day or several hours, for example, 12 hours, and may be adjusted according to the actual use situation, which is not limited in this embodiment.

S200, determining an IMEI set corresponding to the double-card-slot terminal from IMEIs corresponding to a plurality of terminals according to an IMEI included in XDR ticket data and a preset terminal library;

the terminal library comprises TACs corresponding to the double-card-slot terminals; wherein, TAC is sent to terminal equipment manufacturer by Global System for Mobile communications Association (GSMA), one TAC can only be allocated to one product model for use; theoretically, 100 ten thousand IMEIs can be generated, and after 100 ten thousand IMEIs are used up, a new TAC is required to be applied. And TACs of all the terminal equipment can be obtained through open source data of a terminal equipment manufacturer.

In the embodiment of the application, the pre-configured terminal library is used for filtering out the single-card-slot terminals by using the TAC code (namely the first eight bits of the IMEI), and in actual use, the single-card-slot terminal can only use one SIM card due to the condition limitation of the terminal hardware, so that the scheme provided by the embodiment does not analyze the state of the terminal. For example, if the TAC included in the IMEI of a certain terminal is not included in the terminal library, it is determined that the terminal is not a dual card slot terminal but a single card slot terminal, and otherwise, if the TAC is included in the terminal library, it is determined that the terminal is a dual card slot terminal.

In a possible implementation manner of the embodiment of the present application, the terminal library includes TACs corresponding to dual-card slot terminals supporting 4G and/or 5G. In the embodiment of the application, the TACs of the dual-card slot terminal supporting 4G or 5G can be screened out based on open source data of a terminal equipment manufacturer, and a terminal library is constructed and periodically updated.

For example, the open source data of the terminal equipment manufacturer includes IMEIs supporting 2G, 3G, 4G, 5G terminals, and in actual use, because 2G and 3G networks are relatively old in technology and are going to quit; meanwhile, because 2G and 3G networks have small bandwidth and low speed, the service occupation ratio of 2G and 3G terminal users is small, and the analysis value is low; in recent years, with the updating and upgrading of terminals, users using 2G and 3G terminals are few, so that the TACs of the double-card-slot terminals supporting 4G or 5G can be screened out and put into a terminal library without bringing the 2G and 3G terminal users into an analysis range. Therefore, the IMEIs of the 2G and 3G terminals can be filtered, the quantity of the IMEIs in the IMEI set can be reduced, data can be simplified, time can be saved in the actual execution process, efficiency is improved, and the calculation force requirement in the actual use of the method is reduced.

S300, performing IMEI pair matching on the IMEI set corresponding to the double-card slot terminal;

in a possible implementation manner of the embodiment of the present application, as shown in fig. 3, for a first IMEI in an IMEI set, the first IMEI is any first IMEI in the IMEI set, and performing dual mobile internet IMEI pair matching includes:

s300a, acquiring a second IMEI from the IMEI set, and if a TAC corresponding to the second IMEI is the same as a TAC corresponding to the first IMEI, and the second IMEI and the first IMEI meet time-space synchronization, and the number of updating synchronization is greater than or equal to a preset number, determining that the first IMEI and the second IMEI are a double mobile Internet IMEI pair;

the preset times are 10 times, and if the first IMEI and the second IMEI are IMEIs corresponding to two SIM cards of one terminal, the first IMEI and the second IMEI can satisfy multiple time-space synchronization and updating synchronization; occasionally, meeting the spatio-temporal synchronization and the update synchronization once or twice may be caused by some small probability event. The preset times in actual use can be modified according to actual use requirements.

Wherein the space-time synchronization comprises: respectively using the first IMEI and the second IMEI to execute the time difference of the same type of communication events to be smaller than a preset time threshold, and the corresponding inter-cell distance to be smaller than a preset distance threshold;

the same type of communication event includes: attach in 4G network (corresponding to initial Registration in 5G network), detach in 4G network (corresponding to De-initial Registration De _ Registration in 5G network), handover in 4G network (corresponding to Handover in 5G network).

For example, the first IMEI and the second IMEI execute the same type of communication event, and may be: the first IMEI executes attach in the 4G network, the second IMEI executes attach in the 4G network or the second IMEI executes Registration in the 5G network; the first IMEI executes detach in a 4G network, the second IMEI executes detach in the 4G network or the second IMEI executes De _ registration in a 5G network; the first IMEI performs Handover in a 4G network, the second IMEI performs detach in a 4G network, or the second IMEI performs De _ registration in a 5G network.

The time threshold may be 10s, the distance threshold may be 1km; it can be understood that, in practical use, when two SIM cards of a dual-card terminal are used, signaling data generated by the two SIM cards certainly meet space-time synchronism, that is, attachment and detachment (corresponding to initial registration and de-initial registration of a 5G network) and switching are performed simultaneously; synchronization of the signalling tracks (i.e. location area updates for mobility management are synchronized) will also be met. Meanwhile, the application considers some accidental situations; for example, when two SIM cards, SIMa and SIMb, of the same terminal are attached to, detached from (corresponding to initial registration and de-initial registration of a 5G network) or updated in a location area for mobility management, the SIMa and SIMb may not interact with the same cell in signaling due to the influence of some special factors (e.g. fluctuation of network environment); therefore, the cells used by SIMa and SIMb are not exactly the same, but are not particularly far away from each other, so that the embodiment of the present application selects 1km as the distance threshold to determine the spatial consistency between them, and can eliminate the interference of some special factors on the determination of spatial consistency. Similarly, because of fluctuation of a network environment, the time of the two SIM cards is not strictly the same when the two SIM cards are attached or detached (corresponding to the initial registration or the de-initial registration of the 5G network) or when the location area of the mobility management is updated, so in the embodiment of the present application, 10s is used as a threshold to determine the time consistency of the two SIM cards, and the interference of some special factors on the time consistency determination can be eliminated. It is understood that, in practical applications, both the time threshold and the distance threshold may be adaptively adjusted according to the needs of practical applications.

Wherein, the calculation of the cell distance comprises the following steps: respectively acquiring cell numbers corresponding to cells where the first IMEI and the second IMEI reside when executing the same-type communication event or executing location area updating based on mobility management, matching the cell numbers with cell parameters to obtain the longitude and latitude of the cells, and calculating the cell distance based on the longitude and latitude of the cells.

Wherein the cell parameter is a data determined at the beginning of the setting of the cell; when the method is used, for example, the latitude and longitude of the cell, the model information of the cell base station and the like can be inquired through the cell number region. In one possible embodiment of the present application, the cell distance d (cell) ₁ ,cell ₂ ) Can be calculated by the following formula:

wherein, R is the radius of the earth, and can be 6378km in practical use; lat1, lat2, lng1, and lng2 are cells, respectively ₁ 、cell ₂ The longitude and latitude of two cells.

Specifically, an exemplary IMEI set obtained in step S200 in the embodiment of the present application is shown in table 1:

TABLE 1

TAC code	a_imei	b_imei
			12345678	123456786591483	1234567865914**

12345678	123456786591483	1234567824866**

As can be seen from table 1, there may be multiple IMEI codes matching with the TAC code (12345678) of the same terminal; therefore, further matching of IMEI through time synchronization and space synchronization is required.

The data in table 1 is subjected to synchronous event judgment in step S300a, and the obtained exemplary data are shown in tables 2 and 3:

2022/4/12 13:51:11	2022/4/12 13:51:11	123456789591475	123456789	attach

As can be seen from table 2, the data with IMEI 123456789591483 and the data with IMEI 123456789591475, both of which use the same cell (eci is the same) in performing attach, and have a time of 2022/4/12.

As can be seen from table 3, the data with IMEI 123456789591483 is identical to the data with IMEI 123456789591475, both of which use the same cell when tau is performed (eci is identical), and its time is 2022/4/12 07.

Because the states of two IMEIs in the IMEI pair of the dual mobile internet are the home network dual cards, the corresponding terminal positions of the two IMEIs are also certain same, and the cells used by the two IMEIs for signaling data transmission are not far apart in consideration of the fluctuation of a network environment; optionally, in the embodiment of the present application, the matching of the IMEI pair in the dual mobile internet may also be reviewed, including:

s300b, judging whether the occupied inter-cell distance is more than 2km when one IMEI and the other IMEI in the pair of IMEIs of the dual mobile internet are subjected to signaling data transmission within a preset time threshold, and if the occupied inter-cell distance is more than 2km, canceling the pair of IMEIs of the first IMEI and the second IMEI.

Therefore, matching is rechecked through the IMEI of the dual-mobile internet, accuracy of judging the synchronous events can be improved, abnormal data can be filtered, the obtained dual-card state can better meet the actual situation, and accuracy of identifying the dual-card state can be further improved.

S400, determining the double-card state of the double-card slot terminal according to the matching result and the communication data corresponding to the IMEI; the IMEI pair of the double mobile internets comprises the same double-slot terminal and corresponds to two different IMEIs of the first mobile internet.

Understandably, the states of two IMEIs in the IMEI pair of the dual mobile internet are the home network dual cards.

Based on this, in the embodiment of the present application, the inter-cell distance pair is used for performing the time-space synchronization determination and the update synchronization determination, and compared with the prior art that an LAC is used when determining whether the update position is synchronized, because the geographic area covered by the LAC is larger, there is a possibility of a great misdetermination. For example, the terminals of the two different network sub-cards of the home network main card perform position movement at the same position of the LAC code at the same time, and move into two cells with the same LAC; because the LAC codes are the same and the time for carrying out position movement is the same, the SIM cards which are supposed to belong to two terminals are judged to belong to the same network double cards of one terminal by using the LAC, and misjudgment is generated; the communication data and/or the cell distance between the communication data and/or the communication data (or the communication data is referred to as the resident cell) are used in the method, the space-time synchronization judgment is carried out from the dimension of the communication data and/or the cell to update the judgment, and the cell is smaller relative to the area covered by the LAC; the judgment can be more precise, and the obtained double-card type can be more accurate. According to the embodiment of the application, the IMEI pair is matched through analyzing the consistency of the terminal types and the time-space synchronism of the signaling track, and the primary and secondary card slots of the dual-connection user can be identified according to the service volume characteristics subsequently.

In a possible implementation manner of the embodiment of the present application, the matching result includes matching success or matching failure; successful matching can mean that two SIM cards using the first mobile Internet service exist on the double-card-slot terminal, and failed matching can mean that two SIM cards using the first mobile Internet service do not exist on the double-card-slot terminal, and only one SIM card can be started to use the first mobile Internet communication, and the other SIM card does not work, such as being in a flight mode; or one SIM card uses a first mobile internet communication, the other uses a second mobile internet communication or uses wifi or shared hotspot communication, etc. Specifically, S400 specifically includes steps S4001 to S4002d shown in fig. 4:

s4001, if the matching is successful, determining a double-card state of the double-card-slot terminal according to the corresponding traffic volume of the IMEI of the double-mobile internet.

In this scenario, the service data information includes the size of the service volume; as a possible implementation manner of the embodiment of the present application, of the two IMEIs included in the pair of IMEIs of the dual mobile internet, the IMEI with a relatively large traffic is used as a dual card primary card, and the IMEI with a relatively small traffic is used as a dual card secondary card. The IMEI as a dual card primary card in the present application may be understood as a SIM card corresponding to the IMEI as a dual card primary card, and the IMEI as a dual card secondary card may be understood as a SIM card corresponding to the IMEI as a dual card secondary card.

It can be understood that, in actual use, the size of the service volume can be judged by judging the number of the user plane call tickets of the two IMEIs and the signaling plane call ticket data area, and specifically, how to judge the size of the service volume is the prior art, and is not described herein again.

After obtaining the dual-card main card and the dual-card auxiliary card, the operator can give different marketing activities based on different user types; for example, a flow upgrade package is recommended to a dual-network main card user, a call upgrade package is provided for a dual-network auxiliary card user, and the like, so that an operator can more accurately market the user, actual use requirements of the user are better met, user experience is enhanced, and user stickiness is improved.

S4002, if the matching fails, determining a double-card state of the double-card-slot terminal according to the service data information corresponding to the IMEI and the cell number.

In a possible implementation manner of the embodiment of the present application, determining a dual card state of the dual card slot terminal according to service data information corresponding to the IMEI and the cell number in S4002 includes:

s4002a, judging the number of user plane call tickets corresponding to the IMEI according to a preset number threshold, and taking the IMEI with the number of the user plane call tickets being larger than the number threshold as a home network master card;

as a possible implementation of the embodiment of the present application, the number threshold is 0. In practical use of a user, generally, no matter whether a terminal performs data or voice service, as long as the terminal is in a power-on state, data is always generated on a signaling plane: such as location updates (periodic, mobility), attach, detach, etc. At present, a plurality of Applications (APP) are generally installed in a widely-used smart machine, and even if a user does not open a terminal for use, the APP runs in a background, and data interaction such as heartbeat packet and message push and the like between the APP and a service end of the APP still needs to be carried out through data network connection; therefore, even if the user does not perform service operation and use the APP, a small amount of traffic bills are generated, and the bills are generated on the user plane, so that the amount of the bill on the user plane is not zero. For most users, if only signaling plane data exists in the network, no traffic ticket is generated on the user plane, and the user plane ticket is zero, the terminal is more likely not to use the SIM card as a data network connection; if a large number of traffic bills exist on the user plane while the traffic bills are generated on the signaling plane, the SIM card can be considered to be used as a main card, i.e. the state of the SIM card is the main card of the home network.

S4002b, if the number of the user plane call tickets is smaller than a number threshold, judging whether a distribution index corresponding to the IMEI is larger than a preset distribution threshold;

s4002c, using the network secondary card with the distribution index larger than a preset distribution threshold value;

s4002d, using the distribution indexes smaller than a preset distribution threshold value as WIFI users.

The distribution index calculation method comprises the following steps: the method comprises the steps of obtaining cell numbers of a plurality of cells corresponding to the same IMEI, obtaining longitude and latitude information of the plurality of cells based on the cell numbers, calculating the distance between each cell and other cells in the plurality of cells according to the longitude and latitude information, and taking the maximum value of the distance as a distribution index.

As an implementation manner of the embodiment of the present application, the distribution index is calculated by the following formula;

wherein, the distribution index is: max _2cell_distance; d (cell) _i ,cell _j+1 ) Representing two cell cells _i And cell _j+1 The function "max ()" is a maximum function.

It can be understood that, in actual use, the amounts of communication traffic consumed by the WIFI user and the home network sub-card user are both small, so that the home network main card and the home network sub-card user are distinguished only by the communication traffic in the XDR ticket data, and the WIFI user can be mistakenly identified as the home network sub-card user. In the prior art, only the size of the communication traffic consumed by the SIM card is used to distinguish the home network main card from the home network auxiliary card, and it is not further used to distinguish whether the users consuming less communication traffic still include WIFI users; in the embodiment of the application, the WIFI users and the network auxiliary card users are further distinguished through the distribution indexes, compared with the prior art, the method provided by the embodiment of the application is more precise in distinguishing the users, so that the obtained SIM card is more accurate in use state and higher in accuracy. Meanwhile, the operator carries out marketing service or customer maintenance service by using the user state obtained by the method, so that the efficiency of the marketing service can be improved, the user viscosity can be increased, and better experience is brought to the user.

As a possible embodiment of the present application, the preset distribution threshold may be 1km or 500m. It can be understood that in practical use, the signal range of WIFI is small, and the coverage range of a general office or home router is within 50 meters. Therefore, if the network connection used by a terminal is WIFI, the terminal has a significant limitation in the physical movement range. Meanwhile, in practical use, the terminal can not communicate with the cell closest to the terminal due to fluctuation of a wireless communication environment; meanwhile, the situation that the terminal does not physically move and a cell communicated with the terminal is replaced exists; therefore, the embodiment of the application judges whether the distribution index is less than 1km or not to be a WIFI user or not. If the distribution index is smaller than 1km, the physical displacement of the terminal is relatively small and is within the coverage range of WIFI, so that the data network connection of the terminal can be considered to depend on a WIFI network and belong to a WIFI user.

In summary, the embodiment of the present application provides a method for identifying a dual card status of a dual card slot terminal, where a cell number is used to perform SIM card location determination, so as to distinguish the dual card status of the terminal; compared with the method for judging by using the TAC, the method for judging by using the cell number has the advantages that the result obtained by judging by using the cell number is more accurate, the dual-card state identification is more accurate, and the success rate and the accuracy rate of the dual-card state identification are improved. Meanwhile, the distribution obtained by using the cell numbers is adopted in the method, and the WIFI user is judged based on the distribution indexes, so that the use condition of the user on the SIM is considered more comprehensively, the SIM card state is analyzed more comprehensively, and the accuracy of double-card state identification is further improved
