Description

Technical Field

[0001] This document relates to the field of computer technology, and in particular to a method and device for identifying IMEI of a dual-card terminal. Background Art

[0002] Each card slot of the user equipment (UE) corresponds to an International Mobile Equipment Identity (IMEI) of the terminal. When the subscriber identity module (SIM) is inserted into the card slot to log in to the network, its own IMEI will be reported to the network side device for authentication to identify illegal users. With the popularization of dual-card terminals, in order to provide targeted network improvement solutions for dual-card terminals, the network side device needs to identify the IMEI from the same terminal in the received IMEI. However, since the terminal manufacturers are currently unable to provide a database of the binding relationship between the corresponding IMEI and UE, the network side device cannot determine whether the two IMEIs are from the same user terminal.

[0003] Therefore, there is an urgent need for a solution that can accurately identify the IMEI of the same dual-SIM card terminal. Summary of the invention

[0030] In order to make the purpose, technical solutions and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this document.

[0031] In order to accurately identify whether two IMEIs are from the same UE, an embodiment of the present specification provides a method for identifying the IMEI of a dual-card terminal, which utilizes the regularity that different IMEIs of the same UE usually correspond to different mobile phone numbers, different IMEIs of the same UE at the same time have a high probability of having the same coverage cell as the main service cell, and these different IMEIs at the same time have a high probability of overlapping. By analyzing the mobile phone numbers corresponding to each of the multiple IMEIs and the main service cell information, location information and corresponding reporting time points reported within a predetermined time period, the same coverage of the main service cells and the overlap of the positions between these IMEIs within the predetermined time period are determined, and then based on the same coverage of the main service cells and the overlap of the positions, the IMEIs belonging to the same UE among these IMEIs can be identified. This identification method can not only ensure the accuracy of the identification result, but also does not require the terminal manufacturer to provide a database of the binding relationship between the corresponding IMEI and the UE, and does not need to integrate and maintain the databases of different terminal manufacturers, so that the identification of different IMEIs of the same UE is not limited to any terminal manufacturer and has wide applicability.

[0032] It should be understood that the dual-card terminal IMEI identification method provided in the embodiments of this specification can be executed by a network-side device.

[0033] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0034] Please refer to Figure 1 , is a schematic flow chart of a dual-card terminal IMEI identification method provided in an embodiment of this specification, and the method is applied to a network side device. Figure 1 As shown, the method may include:

[0035] S102, obtaining mobile phone numbers corresponding to a plurality of IMEIs to be identified and MDT sampling data within a predetermined time period, wherein the MDT sampling data includes primary serving cell information, location information and corresponding reporting time point reported by the corresponding IMEI to be identified.

[0036] In the embodiment of this specification, the UE to which the IMEI to be identified belongs is a dual-SIM terminal. The network side device can identify whether the UE to which each IMEI belongs is a dual-SIM terminal based on the collected information published by the UE to which each IMEI belongs, and further determine the IMEI to which the UE belongs is a dual-SIM terminal as the IMEI to be identified.

[0037] For the mobile phone number corresponding to each IMEI to be identified, the network-side device can use the masked imeisv function of the core network to collect the IMEI reported by the UE to the core network during registration, switching and Track Area Update (TAU), thereby obtaining the correspondence between the IMEI and the mobile phone number. Furthermore, considering that the same UE may support networks of multiple standards, for the mobile phone number corresponding to each IMEI to be identified in different standard networks, when the network-side device collects the IMEI reported by the UE to the core network, it can establish the correspondence between the IMEI and the mobile phone number in different standard networks according to the IMEI reported by the UE to the core network of different standard networks. For example, taking the UE supporting 4G network and 5G network as an example, the IMEI reported by the mobile UE to the 4G core network (4G EPG) and the 5G core network (5GC) during registration, switching and TAU respectively, and further based on the IMEI reported by the UE to the 4G EPG, the mobile phone number corresponding to the IMEI in the 4G network is determined, and based on the IMEI reported by the UE to the 5GC, the mobile phone number corresponding to the IMEI in the 5G network is determined.

[0038] Similarly, since the same UE may support networks of multiple standards, different IMEIs from the same UE may appear in the same standard network (such as 4G network, 5G network) and the main service cells reported are the same coverage cells. For example, different IMEIs report the same coverage cells as the main service cells on the 4G network or the same coverage cells as the main service cells on the 5G network. Of course, it is also possible that the main service cells reported on different standard networks are the same coverage cells, such as the main service cell reported by one IMEI on the 4G network and the main service cell reported by another IMEI on the 5G network are the same coverage cells. In view of this, in the above S102, the Minimization of Drive Test (MDT) sampling data of each IMEI to be identified within a predetermined time period may include the MDT sampling data of the IMEI to be identified in multiple standard networks.

[0039] Furthermore, in order to facilitate the subsequent more accurate determination of the same coverage and location overlap of the main service cells between different IMEIs, in the embodiments of this specification, after obtaining the mobile phone numbers corresponding to the multiple IMEIs to be identified in various standard networks and the MDT sampling data corresponding to the multiple standard networks in a predetermined time period, for each standard network, according to the order of reporting time points, based on the mobile phone numbers and MDT sampling data corresponding to each IMEI to be identified in the standard network, a time series data set corresponding to each IMEI to be identified in the standard network can be constructed. For example, taking 4G network and 5G network as examples, the time series data sets corresponding to the IMEI to be identified in different standard networks are as follows:

[0040] f 4G (m x ,t n )={m x ,Cell(t n ),Positon(t n )}

[0041] f 5G (M x ,T n )={M x ,Cell(T n ),Positon(T n )}

[0042] Among them, f 4G (m x ,t n ) represents the time series data set corresponding to the xth IMEI to be identified in the 4G network, m x Indicates the mobile phone number corresponding to the IMEI to be identified in the 4G network, t n Indicates the nth reporting time point of the IMEI to be identified in the 4G network, Cell(t n ) indicates that the IMEI to be identified is at the reporting time point t n The main service cell reported through the 4G network, Positon(t n ) indicates that the IMEI to be identified is at the reporting time point t n Location information reported via 4G network; 5G (M x ,T n ) represents the time series data set corresponding to the xth IMEI to be identified in the 5G network, M x Indicates the mobile phone number corresponding to the IMEI to be identified in the 5G network, T n Indicates the nth reporting time point of the IMEI to be identified in the 5G network, Cell(T n ) indicates that the IMEI to be identified is at the reporting time point Tn The main service cell reported by the 5G network, Positon (T n ) indicates that the IMEI to be identified is at the reporting time point T n Location information reported through 5G network.

[0043] S104, determining the primary service cell coverage status among the multiple IMEIs to be identified based on the mobile phone numbers corresponding to the multiple IMEIs to be identified, the primary service cell information reported within a predetermined time period, and the corresponding reporting time points.

[0044] In the embodiments of this specification, the same coverage situation of the main service cell between multiple IMEIs to be identified is used to reflect the situation that the main service cells reported by the multiple IMEIs to be identified at the same time point appear to be the same coverage cell. As mentioned above, different IMEIs from the same UE may appear in the main service cell reported as the same coverage cell under the same standard network and the main service cell reported as the same coverage cell under different standard networks. Based on this, in an optional implementation, the above-mentioned main service cell same coverage situation may include: the same coverage IMEI corresponding to each IMEI to be identified under multiple standard network combinations and the number of times the same coverage IMEI appears within a predetermined time period, wherein the same coverage IMEI is an IMEI that is different from the mobile phone number corresponding to each IMEI to be identified and the main service cell reported at the same reporting time point is the same coverage cell.

[0045] Accordingly, the above S104 may include the following steps:

[0046] Step A1, take each IMEI to be identified as the target IMEI, for each reporting time point of the target IMEI itself, based on the first mobile phone number corresponding to the target IMEI and the first main service cell information reported at the reporting time point, select from multiple IMEIs to be identified the IMEI that has the same first mobile phone number corresponding to each target IMEI and the same coverage cell as the first main service cell reported by each target IMEI at the reporting time point, and determine it as the same coverage IMEI of the target IMEI corresponding to the reporting time point under the first network combination.

[0047] Among them, for each IMEI to be identified, the first mobile phone number of the IMEI to be identified refers to the mobile phone number corresponding to the IMEI to be identified in the first standard network, and the first main service cell of the IMEI to be identified is the main service cell reported by the IMEI to be identified through the first standard network. The first standard network is any one of the above-mentioned multiple standard networks, such as 4G network and 5G network. Therefore, the same coverage IMEI of the target IMEI under the first standard network combination is the IMEI whose main service cell reported by the target IMEI through the same standard network is the same coverage cell.

[0048] For example, for the case where multiple IMEIs to be identified have the same coverage in the primary service cell of the 5G network, if a mobile phone number M corresponding to a certain IMEI to be identified in the 5G network x 'The mobile phone number M corresponding to the target IMEI on the 5G network x If the primary service cell reported by the target IMEI through the 5G network at the reporting time point Tn is the same as the primary service cell reported by the target IMEI through the 5G network at the same reporting time point Tn, then the target IMEI can be determined to be the target IMEI in the 5G network corresponding to the same coverage cell at the reporting time point Tn. The above steps are performed for each reporting time point of the target IMEI, thereby determining the target IMEI in the 5G network corresponding to each reporting time point of itself.

[0049] Similarly, for example, if multiple IMEIs to be identified have the same coverage in the primary service cell of the 4G network, if a mobile phone number m corresponding to a certain IMEI to be identified in the 4G network x 'The mobile phone number corresponding to the target IMEI on the 4G network x If the primary service cell reported by the IMEI to be identified at the reporting time point Tn through the 4G network is the same as the primary service cell reported by the target IMEI through the 4G network at the same reporting time point Tn, then it can be determined that the IMEI to be identified is the same coverage cell of the target IMEI in the 4G network corresponding to the reporting time point Tn. For each reporting time point of the target IMEI, the above steps are performed, thereby determining the same coverage cell of the target IMEI in the 4G network corresponding to each reporting time point of itself.

[0050] Step A2, based on the first mobile phone number corresponding to the target IMEI and the first main service cell information reported at the reporting time point, select from multiple IMEIs to be identified, the IMEI to be identified whose corresponding second mobile phone number is the same as the first mobile phone number corresponding to the target IMEI, and the second main service cell reported at the reporting time point and the first main service cell reported by the target IMEI at the reporting time point are the same coverage cells, and determine it as the same coverage IMEI of the target IMEI corresponding to the reporting time point under the second network combination.

[0051] Among them, for each IMEI to be identified, the second mobile phone number of the IMEI to be identified refers to the mobile phone number corresponding to the IMEI to be identified in the second standard network, and the second main service cell of the IMEI to be identified is the main service cell reported by the IMEI to be identified through the second standard network. The second standard network is any one of the above-mentioned multiple standard networks, and the second standard network is different from the first standard network. For example, if the first standard network is a 4G network, the second standard network is a 5G network. Therefore, the same coverage IMEI of the target IMEI under the second standard network combination is the IMEI whose main service cell reported by the target IMEI through different standard networks is the same coverage cell.

[0052] For example, for the case where multiple IMEIs to be identified have the same coverage in the primary service cell of the 5G-4G network combination, if a mobile phone number m corresponding to a certain IMEI to be identified in the 4G network x 'The mobile phone number M corresponding to the target IMEI on the 5G network x If the primary service cell reported by the target IMEI through the 5G network at the same reporting time point Tn and the primary service cell reported by the target IMEI through the 4G network at the same reporting time point Tn are the same coverage cells, then the IMEI to be identified can be determined to be the same coverage cell of the target IMEI corresponding to the reporting time point Tn under the 5G-4G network combination. For each reporting time point of the target IMEI, the above steps are performed, thereby determining the same coverage cell of the target IMEI corresponding to each reporting time point of itself under the 5G-4G network combination.

[0053] Step A3, for various standard network combinations, based on the same coverage IMEIs corresponding to the target IMEI at each reporting time point under the standard network combination, determine the same coverage IMEI corresponding to the target IMEI under the standard network combination and the number of times the same coverage IMEI appears within a predetermined time period.

[0054] For various standard network combinations, by performing statistical analysis on the same-coverage IMEIs corresponding to the target IMEI at each reporting time point under the standard network combination, the same-coverage IMEIs corresponding to the target IMEI under the standard network combination and the number of times each same-coverage IMEI appears within the predetermined time period can be obtained.

[0055] It can be understood that the main service cell coverage between multiple IMEIs to be identified determined through the above-mentioned implementation method can comprehensively and objectively reflect the main service cell coverage between these IMEIs to be identified under the same standard network and the main service cell coverage under different standard network combinations, providing strong data support for the subsequent accurate identification of IMEIs from the same UE.

[0056] Of course, it should be noted that the same coverage of the primary service cells between multiple IMEIs to be identified can also be determined in various ways known to those skilled in the art, and the embodiments of this specification do not specifically limit this.

[0057] S106, determining the position overlap between the multiple IMEIs to be identified based on the position information reported by the multiple IMEIs to be identified within a predetermined time period and the corresponding reporting time points.

[0058] In the embodiment of this specification, the position overlap situation is used to indicate whether the positions of the multiple IMEIs to be identified overlap at the same reporting time point. In an optional implementation, the above S106 may include the following steps:

[0059] Step B1, for each reporting time point of the first IMEI to be identified, based on the position information of the first IMEI to be identified and the second IMEI to be identified at the reporting time point, determine the distance between the first IMEI to be identified and the second IMEI to be identified at the reporting time point.

[0060] The first IMEI to be identified and the second IMEI to be identified are different IMEIs to be identified among the multiple IMEIs to be identified.

[0061] Step B2: if the distance between the first IMEI to be identified and the second IMEI to be identified at the reporting time point is less than a preset distance threshold, it is determined that the first IMEI to be identified and the second IMEI to be identified overlap at the reporting time point.

[0062] The preset distance threshold can be set according to actual needs, and the embodiments of this specification do not specifically limit this. For example, the preset distance threshold can be set to 20 meters. Of course, if the recognition accuracy is to be improved, the preset distance threshold can be set to a smaller value, such as 5 meters.

[0063] It can be understood that the position overlap between multiple IMEIs to be identified determined by the above implementation method can comprehensively and objectively reflect the situation where the positions of these IMEIs to be identified overlap at different time points within a predetermined time period, thereby providing strong data support for the subsequent accurate identification of IMEIs from the same UE.

[0064] Of course, it should be noted that the overlap of positions between multiple IMEIs to be identified can also be determined in various ways known to those skilled in the art, and the embodiments of this specification do not specifically limit this.

[0065] S108, determining the IMEI belonging to the same UE among the multiple IMEIs to be identified based on the same coverage of the primary serving cells and the overlap of the positions of the multiple IMEIs to be identified.

[0066] Under normal circumstances, different IMEIs of the same UE usually correspond to different mobile phone numbers, and the main service cells of different IMEIs of the same UE at the same time are most likely to be the same coverage cells, and the positions of these different IMEIs at the same time are most likely to overlap. Based on this, if the main service cells reported multiple times between two IMEIs to be identified within a predetermined time period are the same coverage cells, and there are multiple position overlaps, then it can be determined that the two IMEIs to be identified are from the same UE.

[0067] Furthermore, considering that different IMEIs to be identified may have the same coverage cell as the reported primary serving cell in the same network standard or in different network standards, in order to further improve the recognition accuracy of the IMEI from the same UE, in an optional implementation, the above S108 may include the following steps:

[0068] Step C1, respectively taking each IMEI to be identified as a target IMEI, for various standard network combinations, from the IMEIs with the same coverage of the target IMEI under the standard network combination, the IMEI with the same coverage that appears the number of times in a predetermined time period that meets the preset number of conditions is selected as the IMEI to be matched corresponding to the target IMEI in the standard network combination.

[0069] Among them, the preset number condition can be that the number of occurrences within the predetermined time period exceeds the preset number threshold or the number of occurrences within the predetermined time period is in the first preset number of digits, etc., which can be set according to actual needs, and the embodiments of this specification do not make specific limitations on this.

[0070] If the number of times that two IMEIs report that the main service cells are the same coverage cells within a certain time period is greater, it indicates that the two IMEIs are likely to come from the same UE. Based on this, for various network combinations, the same coverage IMEI whose number of appearances within a predetermined time period meets the preset number conditions is selected from the same coverage IMEI of the target IMEI under the network combination as the IMEI to be matched corresponding to the target IMEI in the network combination. The selected IMEI to be matched is likely to be the IMEI from the same UE as the target IMEI.

[0071] For example, the target IMEI under the 4G network can be sorted in descending order of the number of occurrences, and the top 10 IMEIs are selected from the IMEIs according to the sorting result as the IMEIs to be matched corresponding to the target IMEI under the 4G network, including Cover(m X )={m1',m2',m3'……m n '}, where n≤10. Similarly, the IMEI to be matched corresponding to the target IMEI in the 5G network includes Cover(M X )={M1',M2',M3'……M n '}, and the IMEI to be matched corresponding to the target IMEI under the 5G-4G network combination includes Cover(M X )={m1',m2',m3'……m n '}.

[0072] Step C2, based on the position overlap between the multiple IMEIs to be identified, determining the number of times the target IMEI and the IMEI to be matched corresponding to the network combination of the standard occur position overlap within a predetermined time period.

[0073] Since the position overlap between multiple IMEIs to be identified can reflect whether there is position overlap between multiple IMEIs to be identified at the same reporting time point, based on the position overlap, the number of position overlaps between the target IMEI and the IMEI to be matched corresponding to the target IMEI in different network combinations within a predetermined time period can be further determined.

[0074] Step C3, from the IMEIs with the same coverage corresponding to the target IMEI under the standard network combination, select the IMEI to be matched that has the highest number of position overlaps with the target IMEI within a predetermined time period, and the number of position overlaps exceeds the number threshold matching the predetermined time period, and determine it as the IMEI belonging to the same UE as the target IMEI under the standard network combination.

[0075] If a certain IMEI with the same coverage of the target IMEI has more times of position overlap with the target IMEI in the predetermined time period, it means that the possibility that the IMEI with the same coverage and the target IMEI are from the same UE is greater, and considering that there are differences in the number of time points for reporting MDT data in different time periods of the target IMEI, based on this, the IMEI to be matched that has the highest number of position overlaps with the target IMEI in the predetermined time period and the number of position overlaps exceeds the threshold of the number of times matching the predetermined time period can be determined as the IMEI belonging to the same UE as the target IMEI under the network combination of this standard.

[0076] The number thresholds for matching different scheduled time periods can be set according to actual needs. For example, if the scheduled time period is one week and the scheduled time period includes 7×24×2 sampling points, the number threshold for matching the scheduled time period can be set to 188 times.

[0077] Taking into account that there may be multiple IMEIs to be matched that have the highest number of position overlaps with the target IMEI within the predetermined time period and the number of position overlaps exceeding the number threshold matching the predetermined time period, and for dual-card terminals, there can only be one IMEI from the same UE as the target IMEI, in order to accurately identify the IMEI from the same UE as the target IMEI, further, before the above S183, it also includes: determining that the number of IMEIs to be matched that have the highest number of position overlaps with the target IMEI within the predetermined time period and the number of position overlaps exceeding the number threshold matching the predetermined time period is one, if the number is multiple, repeating the steps of selecting the IMEI to be matched that has the highest number of position overlaps with the target IMEI within the predetermined time period and the number of position overlaps exceeding the number threshold matching the predetermined time period in the above steps S102 to S183, until the number of selected IMEIs to be matched is one.

[0078] The method for identifying the IMEI of a dual-card terminal provided in the embodiments of this specification utilizes the regularity that different IMEIs of the same UE usually correspond to different mobile phone numbers, different IMEIs of the same UE at the same time have a high probability of having the same coverage cell as the main service cell, and these different IMEIs at the same time have a high probability of overlapping. By analyzing the mobile phone numbers corresponding to each of the multiple IMEIs and the main service cell information, location information and corresponding reporting time points reported within a predetermined time period, the main service cell co-coverage and position overlap between these IMEIs within the predetermined time period are determined, and then based on the main service cell co-coverage and position overlap, the IMEI belonging to the same UE among these IMEIs can be identified. This identification method not only ensures the accuracy of the identification result, but also does not require the terminal manufacturer to provide a database of the binding relationship between the corresponding IMEI and the UE, and does not require the integration and maintenance of databases of different terminal manufacturers, so that the identification of different IMEIs of the same UE is not limited to any terminal manufacturer and has wide applicability.

[0079] In another embodiment, in order to enable relevant personnel to quickly and conveniently obtain the IMEI, mobile phone number and network used by each UE, such as Figure 2 As shown, after the above S108, the method provided in the embodiment of this specification may further include:

[0080] S110, based on the target IMEI and the corresponding mobile phone number and the IMEI and the corresponding mobile phone number of the same UE as the target IMEI under various network combinations, updating a preset database.

[0081] The preset database stores the correspondence between the IMEI and the corresponding mobile phone number, the standard network combination and the terminal type to which the UE belongs. For example, the following Table 1 shows an example of the correspondence between the IMEI and the corresponding mobile phone number, the standard network combination and the terminal type to which the UE belongs.

[0083]

[0084] In another embodiment, in order to provide targeted network improvement solutions for different UEs (especially dual-SIM UEs), such as Figure 2 As shown, after the above S110, the method provided in the embodiment of this specification may further include:

[0085] S112: Based on the corresponding relationship stored in the preset database, determine the portrait data of the UE in the terminal configuration dimension in the preset database.

[0086] The UE portrait data in the terminal configuration dimension is used to describe the terminal configuration of the UE, such as whether the UE's standard network is configured normally.

[0087] For example, if a dual-card 5G UE has two SIM cards and the UE chip capability supports it, the 5G switch is turned on normally, or if the dual-card 5G UE has one SIM card and the UE's 5G switch is turned on normally, it is determined that the UE's standard network configuration is normal.

[0088] If the dual-SIM 5G UE has two SIM cards but the UE chip capabilities support it, but the 5G switches are not all turned on normally, or if the dual-SIM 5G UE has one SIM card and the UE chip capabilities support it, but the 5G switches are not all turned on normally, it is determined that the network configuration of the UE is abnormal.

[0089] S 114, determining the portrait data of the UE in the business dimension based on the business-related data of the UE in the preset database.

[0090] The service-related data of the UE may be data related to services used by the UE pre-acquired from a service database. The portrait data of the UE in the service dimension is used to describe the service usage of the UE, such as whether the service market of the UE is saturated.

[0091] It should be noted that the portrait data of the UE in the service dimension can be determined by various methods known to those skilled in the art, and the embodiments of this specification do not specifically limit this.

[0092] S116, generating a user portrait of the UE based on the portrait data of the UE in the terminal configuration dimension and the service dimension respectively.

[0093] Among them, Figure 3 As shown, the four-quadrant method can be used to map the UE to different quadrants based on the portrait data of the UE in the terminal configuration dimension and the service dimension, thereby obtaining the user portrait of the UE. For example, the following Table 2 shows an example of the portrait data of different UEs in the terminal configuration dimension and the service dimension in the preset database and the generated user portrait.

[0094] Table 2

[0095]

[0096]

[0097] Furthermore, for each UE in the preset database, after generating a user portrait of the UE, different plans for improving the retention rate and precision marketing can be formulated from the network, market, and user behavior sides based on the user portrait of the UE.

[0098] Specifically, for normally configured UEs, which are focused on improving network capabilities, the main strategies are to aggregate reverse flow and high-value potential demand, improve 5G planning and promote site opening; improve 5G and anchor point deep coverage; RF optimization, parameter optimization, and interference troubleshooting to improve the 5G diversion ratio after 5G network access.

[0099] For user-configured UEs, the main reason why the terminal cannot stay in 5G is that the 5G switch is not turned on. Focus on the automatic turning on of the 5G switch during the terminal company version upgrade and the manual turning on of the 5G switch during the marketing promotion. At the same time, take into account the network improvement of normal configuration.

[0100] For the UE with market demand, this UE belongs to the type of market to seize the second card slot. Focus on market publicity, tapping potential, and seizing the second card slot to increase market share.

[0101] For the user market type UE, this UE belongs to the type of market to seize the second card slot and 5G switch on. Focus on the 5G switch on after the market share is increased.

[0102] It is understandable that according to the user portrait of UE, the 5G diversion ratio solution is improved by linking the network, market and terminal configuration in three aspects according to the scenario classification. Among them, according to the movement trajectory of normal configuration users, converged to a 50*50 grid, the network solution is improved in a targeted manner, which can greatly improve the 5G residence ratio.
