While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of an identification method for a single-terminal dual-card user according to an embodiment of the present invention.
As shown in fig. 1, the method comprises the steps of:
and step 13, processing the first pairing database to obtain a second pairing database, wherein the second pairing database comprises information of single-terminal double-card users.
In the method for identifying a single-terminal dual-card user according to the embodiment, first information when at least two identification module card users belonging to the same operator register to a network side is obtained; obtaining a first pairing database according to the first information, wherein the first pairing database comprises information of suspected single-terminal double-card users; and processing the first pairing database to obtain a second pairing database, wherein the second pairing database comprises information of the single-terminal double-card user. The method for judging the single-terminal double-card users of the same operator through the network side is realized, the suspected paired double-card terminal database is formed, and the paired double-card terminal database is put in and taken out of the database at the later stage, so that the beneficial effect of better network optimization work is obtained.
In an alternative embodiment of the present invention, step 11 may include: the method comprises the steps of obtaining time similarity information, geographical position similarity information and/or similarity information between international mobile equipment identification codes IMEI numbers when at least two identification module card users belonging to the same operator register to a network side.
In this embodiment, the time proximity information may be, for example, that a time interval between a first time when the card 1 of the same terminal registers to the network side and a second time when the card 2 registers to the network side is smaller than a preset value; geographic location proximity information, for example, that the card 1 of the same terminal is in the same cell when registered to the network side and the card 2 is in the same cell when registered to the network side; the information of the proximity between IMEI numbers, for example, the IMEI number corresponding to the card 1 is the same as the first N bits of the IMEI corresponding to the card 2, and N is preferably 8. In specific implementation, the similarity of cell-level users at a time point in the process of attaching (LTE network) or initially registering (initial registration is the registration type in NR network) in a certain time period of the whole network is traversed. Taking initial registration in an SA network as an example, selecting the same NR cell as a unit, and traversing registration events within a certain time period (initially selecting a week) to obtain the first information; the time period can determine the period length according to the data volume, the time of one week can be selected preliminarily, and supplement selection is performed in the later period according to the data volume;
and screening the initial registration events of the same NR cell registration type within a certain time range, and selecting a user pair of the secondary events within a 5-second event period, wherein the user pair is temporarily identified by 5G-GUTI. The time range is selected to be 5 seconds, because according to multiple experiments, the registration time difference of the double cards in the single-terminal double-card SA registration process is about within 3 seconds. The terminal uses SUCI only during initial registration, and initiates registration with 5G-GUTI identification in later period.
And analyzing and comparing PEI values fed back in subsequent Identity Response signaling in the registration event aiming at the initial registration within each 5-second time period, wherein the characteristic that the single-terminal double-card user has the IMEI number or the first 8-bit PEI number is consistent.
The PEI in the NR network has the same meaning as the IMEI in the LTE network, and the IMEI in the LTE network is used as an example: the IMEI, which is a mobile phone serial number and a mobile phone serial number, is used to identify each mobile communication device, such as an 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 are model approval numbers which are codes for distinguishing the brand and the model of the mobile phone. The next 2 bits are the last assembly number, representing the final assembly code. The last 6 digits are the string number, representing the production sequence number. The first part of TAC, type Allocation Code, which is composed of 8 digits, is a Code for distinguishing the brand and model of the mobile phone, and the Code is allocated by GSMA and its authorization mechanism. The first two digits of the TAC code are the identifier of the distribution mechanism, and the TAC code is the code of the distribution mechanism authorized by the IMEI code, for example, 01 is CTIA in the united states, 35 is BABT in the united kingdom, and 86 is TAF in china. The first 8 bits of the two IMEI values of the single-terminal dual-card terminal must be identical.
And aiming at the condition that the first 8 bits of PEI numbers fed back by the Identity Response in the initial registration process of the same NR cell within a 5-second time period are consistent, importing the PEI numbers into a first pairing database. The suspected terminal mark LTE side user is marked by IMSI number, NR side user is marked by SUPI, after user completes initial register authentication process, AMF side can obtain user SUPI value from AUSF side, if considering SUPI value is too high relative to machine density, then marking with SUPI value after MD5 can be considered.
In an alternative embodiment of the present invention, step 12 may include: adding paired users, which belong to the same cell and/or have the same preset digits of the IMEI number and have an interval time less than a first preset time period when the paired users initially register to the network side, in the first information into a preset database to obtain a first paired database;
in this embodiment, the network side determines whether multiple cards are suspected to be a single terminal (i.e., the same terminal) by using the proximity (difference at the time point) of the terminal at the time point of the attach (LTE network) or initial registration (the registration type in the NR network is initial registration) process, the proximity of the geographic area (whether the cells where this action occurs are consistent), and the proximity between two IMEI numbers of the single-terminal and dual-card terminals in the Identity Response flow, so as to obtain the first pairing database.
In an alternative embodiment of the present invention, step 13 may include: acquiring a paired user initiating an outgoing call process in the first paired database; and if a first target paired user with the same preset digit belonging to the same cell and/or international mobile equipment identification code IMEI number exists in the paired users initiating the outgoing call process and the interval time for initiating the outgoing call process is less than a second preset time period, and the first target paired user belongs to the same cell and/or the first target paired user is deleted from the first paired database to obtain a second paired database.
In this embodiment, the first pairing database is monitored, and a monitoring period may select a week time, and determine whether a flow of de-registration NR network occurs where a Switch off type (power off type) is used as a Switch off (power off) to de-attach an LTE network or a de-registration type (logout type) is used as a Switch off (power off) for a suspected single-terminal dual-card user.
And analyzing whether the cell consistency or the cell geographical position of the cell in which the user detach and the de-registration occur in 5 seconds and the intra-user simultaneously initiates within the geographic area or the de-attach or the de-registration occur in the suspected single-terminal double-card user pairing database is similar or not again, and once the cell and the similar cell simultaneously initiate the de-attach and the de-registration in the same cell and the similar cell within 5 seconds, importing the MSISDN (mobile phone number) corresponding to the double-card user pair into a second pairing database. The MSISDN corresponding to the SUPI may be obtained directly in the background, and if the first pairing database is defined by the MSISDN number in the early stage, the MSISDN procedure corresponding to the SUPI is omitted. Further, coordinating the BOSS system to query the signed package corresponding to the MSISDN to form a second user pairing database, and providing a basis for later-stage current user network optimization.
Fig. 2 shows a flowchart of a single-terminal dual-card user identification method according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
Specifically, deleting a second target single-terminal dual-card user with no proximity behavior in the second pairing database to obtain a third pairing database; the non-proximity behavior comprises at least one of: the IMEI corresponding to the international mobile subscriber identity IMSI number or the permanent identification information SUPI number of the double cards changes;
the time interval of the initial registration of the double cards to the network side is greater than a third preset time period;
the initial registration is not in the same cell;
the time point of initiating the outgoing call process by the double cards is greater than a fourth preset time period;
the double cards are not in the same cell when initiating an outgoing call process;
the distance between the MDT data home cells reported by the double card side is larger than a first preset distance or the positioning distance is larger than a second preset distance.
This embodiment, after passing through the above steps 21 to 23, further, for the second pairing database, there is also accuracy within a certain period of time, such as the reason that the user changes the terminal, deletes one card therein, and so on, so that this database needs to be maintained. It should be noted that steps 21 to 23 in this embodiment are the same as steps 11 to 13 in the above method, respectively, and all the implementations in the above method are applicable to this embodiment, and the same technical effects can be achieved.
In the embodiment, when an IMEI (International Mobile equipment identity) change corresponding to an IMSI (International Mobile subscriber identity) number or an SUPI (SuperSpecification) number occurs in a paired user, no approximation or no approximation of a geographical position exists at the time point when initial registration (NR network) occurs in a dual card, no approximation or no approximation exists at the time point when de-attachment (LTE network) or de-registration (NR network) with the de-registration type of Switch off occurs in the dual card, and at least one of long distance or long positioning distance between MDT data home cells reported on the dual card side, the second paired database is updated, so that timely updating and maintenance of a single-terminal dual-card user database are realized, and more optimized service is further provided for a single-terminal dual-card user in the database.
