Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, specific implementation modes of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

In order to determine which two IMEIs correspond to the same dual-SIM terminal, related technologies have proposed the following solutions:

Operators accumulate user data for a certain period of time to analyze user trajectories and compare whether user trajectories overlap or are similar during this period to determine which two IMEIs correspond to the same dual-SIM terminal through the terminal location. However, this solution is emerging. It will be more difficult to determine group phenomena and the accuracy will be low;

The association of IMEI is confirmed based on the characteristics of two SIM cards switching between different card slots, the same operator registrant, and the two card slots cannot connect to voice at the same time. However, the card slot characteristics used by these solutions are not universal. For example, when switching card slots, the registrant is the same, or the SIM card in one card slot makes a call while the SIM card in the other card slot has an incoming call, it will happen relatively randomly. Therefore, the two IMEIs of the same dual-card terminal can be identified. There are relatively few cases and the data obtained are not comprehensive.

In order to overcome the shortcomings of the existing technology, the present invention provides a technical solution that can obtain all IMEI associations of dual-card terminals on the network, which will be described in detail below through specific embodiments.

It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence; Furthermore, the embodiments and features in the embodiments of the present invention may be arbitrarily combined with each other as long as there is no conflict.

Figure 1 is a schematic flowchart of a method for determining a terminal identification association relationship provided by an embodiment of the present invention. The method is applied to the operator platform. The operator establishes the corresponding relationship between the terminal and the user through IMEI (International Mobile Equipment Identity), IMSI (International Mobile Subscriber Identity) and phone number. Each dual-SIM device The terminal includes two card slots, each card slot corresponds to an IMEI, and a SIM card inserted in each card slot corresponds to an IMSI. Each SIM card is assigned a phone number when the user purchases it, and the corresponding user information is All are entered into the operator system. However, in actual applications, the IMEI declared and registered by the dual-card terminal can only be the IMEI of the main card. Therefore, the operator cannot obtain the IMEI data of the dual-card terminal on the network based on the declaration data alone. This invention comprehensively considers In view of the shortcomings of existing solutions, a specific implementation plan for confirming the correspondence between two IMEIs of dual-SIM terminals is proposed.

As shown in Figure 1, the method includes the following steps S101 to S104.

S101. Obtain the terminal IDs of all dual-SIM terminal users of the same operator.

The terminal identifier may be an IMEI. Since the two card slots of the dual-SIM terminal each correspond to a unique IMEI in the entire network, the two card slots of the dual-SIM terminal can be effectively distinguished. Of course, in addition to the IMEI, the terminal identifier can also be other identification information that can distinguish the two card slots of the dual-SIM terminal, and the present invention does not limit this.

Since the two card slots of the dual-SIM terminal will each be assigned a unique IMEI before the terminal leaves the factory, the operator platform can obtain the terminal identification of all dual-SIM terminal users on the network by collecting terminal data from the terminal manufacturer and analyzing it. Of course, the terminal IDs of all dual-SIM terminal users on this network can also be obtained through other methods. As for dual-SIM terminal users, they can be 5G (5th Generation Mobile Communication Technology, fifth generation mobile communication technology) users or 4G (4th generation mobile communication technology, fourth generation mobile communication technology) users.

After obtaining the terminal identifiers of all dual-SIM terminal users of the same operator, to facilitate subsequent use, a list of terminal identification information of all dual-SIM terminal users of the same operator can be created, called List A.

S102. Track the terminal identification and calculate the resident cell information of the terminal identification within a preset time period.

In this step, after establishing list A, continue to track the access status of all terminal identifiers in list A to the base station, and calculate the number of times each terminal identifier in list A has entered the base station in a preset time period (such as 15 days, 1 month or 2 months). ) several base station cells that are resident in the network are used as resident cells. To facilitate subsequent use, a list of the counted terminal identities and their corresponding resident cell information can be created, which is called List B.

S103. In response to the first terminal identification switching from the base station corresponding to its resident cell to another base station, obtain the source base station information, switching time and destination base station information of the first terminal identification.

In this step, the first terminal identifier refers to that part of the terminal identifiers among the terminal identifiers of all terminal users of the same operator where the event of switching from the base station corresponding to the resident cell to other base stations occurs. Among the terminal identifiers of all terminal users of the same operator, Each terminal identifier that undergoes a handover event from the base station corresponding to the resident cell to another base station can be called a first terminal identifier, and does not specifically refer to a certain or type of terminal identifier. In other words, each terminal identifier in list B may serve as the first terminal identifier.

Once some terminal identifiers in list B are switched from the base station corresponding to their resident cell to another base station, the terminal identifiers of these base station switches, as well as the corresponding source base station information, switching time and destination base station information are obtained for subsequent steps. .

S104. Select the terminal identification pairs whose source base station information, switching time and destination base station information are consistent from the source base station information, switching time and destination base station information of all first terminal identifications, and combine the two terminals included in each pair of terminal identification pairs. The identification is determined to be two terminal identifications corresponding to the same dual-SIM terminal.

In this step, multiple terminal identification pairs can be filtered out from the information obtained in step S103. If the source base station information, handover time and destination base station information corresponding to the two terminal identifications included in each terminal identification pair are consistent, it can be determined. The two terminal identifiers included in each terminal identifier pair correspond to the same dual-SIM terminal, and the SIM cards of the local network are inserted into the card slots corresponding to the two terminal identifiers.

In a specific implementation, after step S102, the following step S105 is also included.

S105. Send the terminal identification and its corresponding resident cell information to the corresponding signaling analysis system, so that the signaling analysis system monitors the terminal identification in real time, and responds to the first terminal identification from its resident cell. The corresponding base station switches to other base stations, records the source base station information, switching time and destination base station information identified by the first terminal, and reports them to the operator platform.

In this embodiment, after list B recording each terminal identification and its corresponding resident cell information is sent to the corresponding signaling analysis system, each signaling analysis system can monitor each terminal identification in list B in real time. , once the signaling parsing system finds that a certain/certain terminal identification in list B is switched from the base station corresponding to its resident cell to another base station, it records the terminal identification, the corresponding source base station information before the handover, the handover time and the handover corresponding destination base station information, and then report the recorded information to the operator platform.

Correspondingly, step S103 is specifically:

In response to the first terminal identification switching from the base station corresponding to its resident cell to another base station, the source base station information, switching time and destination base station information of the first terminal identification are received from the signaling analysis system, thereby obtaining these information.

In this embodiment, once the signaling analysis system monitors that the first terminal identification is switched from the base station corresponding to its resident cell to another base station, it reports the source base station information, switching time and destination base station information of the first terminal identification to the operator. platform, where the source base station information can be the source base station code, and the destination base station information can be the destination base station code. After receiving this information from the signaling analysis system, the operator platform can establish a terminal identification-source base station code-switching time-destination base station code table based on this information, which is called list C, thereby recording the data reported by the signaling analysis system. for list C.

As time goes by, the data recorded in List C becomes more and more abundant. The data in List C can be accumulated for a period of time before processing the data in List C. The source base station code, switching time and destination base station code in the accumulated data during this period are completely Consistent terminal identification pairs (IMEI pairs) are screened out, and the two terminal identifications included in each terminal identification pair are determined as two terminal identifications corresponding to the same dual-SIM terminal.

In a specific implementation, before step S105, the following step S106 is also included.

S106. Obtain the signaling data in the link through the relevant interfaces in the optical splitting bypass network, and sequentially decode, synthesize, associate each protocol, and backfill user information on the signaling data in the link to obtain the signaling of the terminal access network data.

Correspondingly, step S105 is specifically:

The signaling data is sent to the corresponding signaling analysis system together with the terminal identification and its corresponding resident cell information.

In this embodiment, the operator platform can obtain the signaling data in the link through the relevant interfaces in the optical splitting bypass network, and sequentially decode, synthesize, associate each protocol, and backfill user information on the signaling data in the link. After processing, the signaling data of the terminal access network is obtained. These signaling data record the terminal access network information, and then these signaling data are sent to the corresponding signaling data together with the corresponding terminal identification and the corresponding resident cell information. The analysis system can facilitate the signaling analysis system to monitor the identification of each terminal in real time. Then the signaling analysis system generates real-time messages based on the real-time monitoring results (i.e., terminal identification, source base station information, handover time and destination base station information obtained after base station switching) and reports them to the operator platform for data analysis and processing.

In a specific implementation, after step S103, the following step S107 is also included.

S107. Filter out the remaining terminal identifiers except each pair of terminal identifiers from the source base station information, handover time and destination base station information of all first terminal identifiers, and determine that the dual-SIM terminal where each remaining terminal identifier is located has only one installed. Dual-card terminal for this network's user identification card (SIM card).

In this embodiment, after filtering out pairs of terminal identifiers whose source base station information, handover time and destination base station information are consistent, the remaining unpaired terminal identifiers are also filtered out. The users corresponding to these remaining terminal identifiers are dual-SIM terminals. Only one of the two card slots has a SIM card inserted into the network, allowing the operator to know at any time which users share value with other operators, making it easier for the operator to formulate corresponding operating strategies.

It should be noted that the order of the above steps is only a specific example provided to illustrate the embodiment of the present invention. The present invention does not limit the order of the above steps. Those skilled in the art can adjust it as needed in practical applications; Moreover, the sequence number size of the above steps does not limit the execution order.
