Description

A prompting method, terminal and server

This application claims the priority of the Chinese patent application filed on January 22, 2017 with the application number 201710052278.7 and the title of the invention is "A method and device for preventing fake base station fraud", the entire contents of which are incorporated herein by reference Applying.

technical field

The present application relates to the field of communications, and in particular, to a prompting method, a terminal, and a server.

Background technique

With the development of communication technology, there are more and more cases and means of telecom fraud. Among the numerous telecommunication fraud techniques, committing crimes through illegal base stations or pseudo base stations has become the mainstream means. These fake base stations can pretend to be the base stations of operators and send fraudulent text messages using other people's numbers. The short message sent by the pseudo base station is very confusing because the number can be forged, and it is difficult for the end user to distinguish the true and false.

In the prior art, methods for identifying pseudo base stations are generally a method for identifying pseudo base stations by comparing characteristic parameters of base stations by a terminal, and a method for identifying pseudo base stations based on base station locations. The method of identifying the pseudo base station by comparing the characteristic parameters of the base station by the terminal is as follows: the terminal analyzes the characteristic parameters of the base station and matches with the local preset characteristic parameter library. If it is within the legal range, it is considered as a legal base station. Otherwise, it is considered to be a pseudo base station, and the pseudo base station is directly shielded from the terminal. However, the judgment logic is completely dependent on the terminal, and the system cannot be upgraded. With the development of pseudo base station technology, some characteristic parameters can also be adjusted, but the terminal cannot obtain it dynamically, which may easily lead to misjudgment.

The method for identifying the pseudo base station based on the base station location is as follows: when the terminal receives the notification type short message, it will report the short message and the terminal location information to the server. The server calculates according to the information reported by a large number of terminals, obtains the base station information in a certain area, and then compares it with the location in the operator's base station database. If it is not in the operator's base station database, it is regarded as a pseudo base station. However, there is a risk in this judgment method only for notification messages. The pseudo base station can construct any number, so the text messages sent are not necessarily notification text messages; the operator also has mobile base stations. Not completely reliable; in addition, the base station location reported by the terminal is obtained through algorithm calculation, and there is an error in itself.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

Regarding the above-mentioned method of identifying the pseudo base station by comparing the characteristic parameters of the base station by the terminal: when the terminal accesses the base station, analyze the characteristic parameters of the base station, including the cell identification or the cell identification (CID) of the base station, the location Area identification (location area code, LAC) and system information. Then, the characteristic parameters are matched with the locally preset parameter library, and if they are within the legal range, it is considered to be a legal base station. Otherwise, it is considered to be a pseudo base station, and the pseudo base station is directly shielded from the terminal. The judgment logic of the method is directly preset on the terminal chip, and after judgment, the terminal equipment can be directly blocked from accessing the base station. However, the judgment logic is completely dependent on the terminal, and the system cannot be upgraded. With the development of pseudo base station technology, some characteristic parameters can also be adjusted, but the terminal cannot obtain it dynamically, which may easily lead to misjudgment.

However, the method of identifying pseudo base stations based on the location of the base station is risky for judging only notification messages. The pseudo base station can construct any number that is not necessarily notification SMS; the operator also has mobile base stations. Completely reliable; in addition, the base station location reported by the device side is obtained through algorithm calculation, and there is an error in itself.

In the embodiment of the present application, the technical solution of the present application mainly solves the problem of the accuracy of judgment caused by the inability to update the local parameter database in time, and the problem of the accuracy of judgment caused by the fact that the source of data reporting is limited to notification-type short messages and the operator's mobile base station when using the server for judgment. .

A frame diagram of a communication system applied by the embodiment of the present application is shown in FIG. 1 , and the communication system may include a terminal and a server. As shown in FIG. 2 , which is a schematic diagram of a scenario applied by the embodiments of the present application, the legal base stations that terminals in area A can access include base station No. 2, and the correct base stations that can be accessed in area B are base stations No. 2, 3, and 4.

In this embodiment of the present application, the server may receive information about events reported by a large number of terminals, and the event information may include terminal identification, location information of the terminal, information of the base station accessed when the event occurs, and the time when the event occurs, The event may be receiving a short message or receiving an incoming call. Then, according to the information of the events reported by the large number of terminals, obtain the information of the real base station and the information of the fake base station; the server determines the access fake base station in the large number of terminals according to the information of the real base station and the information of the fake base station. The target terminal of the base station; the server sends the indication information of the pseudo base station to the target terminal. Here, for determining the information of the pseudo base station and the information of the real base station, if more terminals report the information of the event, the result determined by the server is more accurate. The server can then determine, according to the determined information of the real base station and the information of the pseudo base station, the target terminal whose access base station is the pseudo base station among the multiple terminals; The incident aroused vigilance, beware of being deceived.

In the embodiment of the present application, the server can also use the characteristics of the movement of the pseudo base station and the feedback information of the terminal to modify the suspicious probability of the pseudo base station, update the information of the real base station and the information of the pseudo base station, so that the server receives the first terminal next time. When reporting the information of the first event, it can be determined whether the first base station accessed by the terminal when the first event occurs is a pseudo base station according to the updated information of the real base station and the information of the pseudo base station. The accuracy of the result judged by the information and the information of the pseudo base station is higher.

In the embodiment of the present application, the server may also select the information of a batch of base stations with the highest suspicious probability as a positive example, and the information of the base station with the lowest suspicious probability as a negative example according to the suspicious probability corresponding to the information of the real base station and the information of the pseudo base station , and perform model training to obtain the reference weight of each feature included in the information of each base station. The reference weights of these features can be used for the next time the server receives the information of the first event reported by the first terminal, according to the reference weights of the features and the information of the first event, to calculate the first access when the first event occurs. The target probability of a base station. If the target probability is greater than the preset threshold, the server determines that the first base station is a real base station; if the target probability is less than or equal to the preset threshold, the server determines that the first base station is a pseudo base station, and the server sends indication information of the pseudo base station to the terminal. In this way, the server can calculate whether the first base station accessed by the terminal newly received by the server when the first event occurs is a pseudo base station according to the reference weight of each feature and the information of the first event, and provides another method for determining the pseudo base station. The realization method increases the feasibility of the scheme.

In the following, the information reported by a plurality of terminals received by the server in the embodiment of the present application will be specifically described by way of an embodiment. As shown in FIG. 3, it is a schematic diagram of an embodiment of the prompting method in the embodiment of the present application, including:

301. The server receives event information sent by multiple terminals.

In this embodiment of the present application, before the server receives the event information sent by multiple terminals, the terminal detects the occurrence of an event and collects the event information, where the event information may include the terminal identifier (International Mobile Equipment Identity, IMEI), the location information of the terminal, the information of the base station accessed when the event occurs, the time when the event occurs, and the time when the event occurs may also be referred to as a timestamp (timestamp). The terminal sends the information of the event to the server, and it should be understood that the event may include receiving a short message and/or receiving an incoming call. The information of the event may also include information such as the content of the short message and/or the number of the incoming call.

The terminal can be any terminal device including a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales, a sales terminal), a vehicle-mounted computer, etc. In the following example, the terminal can be a mobile phone as example to illustrate. As shown in Figure 4(a), it is a schematic diagram of the interface displayed on the mobile phone for receiving short messages. As shown in Figure 4(b), it is a schematic diagram of the interface displayed on the mobile phone for receiving an incoming call.

The position information of the terminal may be obtained by using a global positioning system (Global Positioning System, GPS), or by using a network to calculate the longitude and latitude. The location information of the terminal may include, but is not limited to, the latitude and longitude, the physical address (Basic Service Setidentifier, BSSID) of the wireless access point that accesses wireless fidelity (Wireless Fidelity, WiFi)/the identifier of the wireless access point or the service set identifier (Service set identifier). Set Identifier, SSID)/Medium Access Control address (Medium Access Control address, MAC addr)/Network ID (NetworkID), the currently scanned WiFi SSID and other information. The information of the base station accessed when the event occurs may include the sector identification of the base station, also called cell identification (cell identification, CID), LAC, adjacent CIDs, and may also include information such as signal strength and cell information.

It should be understood that the information of the base stations accessed by multiple terminals when an event occurs here may be the same or different, and the time at which the event occurs may be the same or different. It is also possible that the same terminal sends information of multiple events, and the information of the multiple events may be the same or different, and is determined by the information of the events actually collected by the terminal.

302. The server acquires the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals.

The server obtains the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals. The server can acquire the information of the real base station and the information of the pseudo base station through the calculation of big data. For the description of the event information sent by multiple terminals, the following example illustrates:

For example, in a possible implementation manner, the server may set a quantity threshold, and when the number of terminals that receive and send event information exceeds the quantity threshold, the server may obtain the real The information of the base station and the information of the pseudo base station.

In another possible implementation manner, the server may further set a specific threshold, and the specific threshold is based on the quantity of the information of the event, that is, when the server receives the information of the event that exceeds the specific threshold, the server can The information of the threshold event obtains the information of the real base station and the information of the pseudo base station.

In another possible implementation manner, the server may further set a preset duration, and the server may obtain the information of the real base station and the information of the pseudo base station according to the information of events sent by multiple terminals received within the preset duration. There may also be other descriptions of the event information sent by multiple terminals, which are not limited here.

The server can obtain the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals in various ways. The following examples will be used to illustrate:

The server can obtain the information of the real base station according to the information of the events sent by the multiple terminals, which can include:

The server determines the information about the longitude, latitude, and date according to the location information of the terminals sent by the multiple terminals, the information of the base station accessed when the event occurs, the time when the event occurs, and the preset location calculation accuracy. The information of the initial base station; the server deletes the information of the initial base station whose number of occurrences in consecutive days is less than the first threshold from the information of the initial base station about the longitude, latitude and date; the server removes the date, The information of other initial base stations is combined to obtain the information about the longitude and latitude of the screened base station; the server determines that the information of the screened base station is the information of the real base station.

Example 1: According to the location information of a large number of terminals (the latitude and longitude obtained by the terminal using the Global Positioning System (GPS), or the latitude and longitude calculated by the network), the base station information accessed by the terminal when receiving a short message and/or an incoming call (here The information of the real base station is determined by the information such as CID and LAC), the time of receiving the short message and/or the incoming call, or the information of the base station currently accessed by the terminal, the information of the adjacent CID and so on.

First, the geographic location adopts a certain calculation precision (such as limiting the decimal places of longitude and latitude, such as being accurate to 5 decimal places), and then combining the data collection date, that is, longitude (longitude, lng), latitude (latitude, lat), date ( date), then, a set of data about longitude, latitude, and date can be obtained at this time [lat, lng, date]={cid, lac; cid, lac; ...}; it should be noted that here, due to lat, lng, Depending on the actual value of date, multiple sets of data about longitude, latitude, and date can be obtained.

For example: [lat1,lng1,date1]={cid1,lac1;cid2,lac2;cid3,lac3};

[lat1,lng2,date1]={cid1,lac1;cid3,lac3;cid4,lac4};

[lat1,lng2,date2]={cid2,lac2;cid3,lac3;cid4,lac4};

[lat2,lng1,date1]={cid8,lac8;cid5,lac5;cid6,lac6};

[lat2,lng2,date1]={cid5,lac5;cid6,lac6;cid7,lac7};

[lat2,lng2,date2]={cid5,lac5;cid6,lac6;cid7,lac7}.

It should be noted that the above are only examples of these groups of data. In practical applications, the number is much larger than the above-mentioned groups of data. Because of a small amount of data, the determined results are not very informative. The embodiment is a solution proposed to improve the accuracy of the obtained pseudo base station. Therefore, the more data there is, the more accurate the determined result will be. Of course, the processing of these data needs to be within the load range of the server.

Secondly, the server merges the data according to the longitude and latitude according to the obtained large amount of data about the longitude, latitude and date. The base station of the latitude and longitude) is eliminated, and the data about the longitude and latitude can be obtained [lat, lng]={cid, lac; cid, lac...}, which means that the base station accessed within the range of the area [lat, lng] is a legal base station, That is, the real base station.

Then, in the above example, since the base station information of {cid8, lac8} appears only once, the base station information of {cid8, lac8} can be deleted, and other base station information can be combined. have[lat1,lng1]={cid1,lac1;cid2,lac2;cid3,lac3};

[lat1,lng2]={cid1,lac1;cid2,lac2;cid3,lac3;cid4,lac4};

[lat2,lng1]={cid8,lac8;cid5,lac5;cid6,lac6};

[lat2, lng2]={cid5, lac5; cid6, lac6; cid7, lac7}, these pieces of information are the information for screening base stations.

Finally, the server obtains a set of information data for screening base stations [lat, lng]={cid, lac; cid, lac...}, then CC=[lat, lng]={cid, lac; cid, lac...}, CC Represents the real base station and can mark the suspicious probability as 0.

In the above example, in the area of [lat1, lng1], the information of the real base station includes {cid1, lac1; cid2, lac2; cid3, lac3}; in the area of [lat1, lng2], the information of the real base station includes {cid1, lac1; cid2, lac2; cid3, lac3; cid4, lac4}; in the area of [lat2, lng1], the real base station information includes {cid8, lac8; cid5, lac5; cid6, lac6}; , lng2] In this area, the information of the real base station includes {cid5, lac5; cid6, lac6; cid7, lac7}.

The server may obtain information about the pseudo base station according to the information of events sent by multiple terminals, which may include:

The server determines, according to the location information of the terminal sent by the multiple terminals, the information of the base station accessed when the event occurs, and the time when the event occurs, the location information of the terminal accessed by the target base station at the first time, and The location information of the terminal accessed at the second time, the target base station is any base station accessed by the multiple terminals when the event occurs; the server is based on the information of the terminal accessed by the target base station at the first time. position information, calculate the first central position of the terminal to be accessed, and calculate the second central position of the terminal to be accessed according to the position information of the terminal accessed by the target base station at the second time; the server determines the The first center position is the first position of the target base station, and the second center position is determined to be the second position of the target base station; if the absolute value of the difference between the first position and the second position is greater than the second threshold, the server determines that the information of the target base station is information of the pseudo base station.

Example 2: The server determines the information of the pseudo base station according to the location information of a large number of terminals, the base station information that the terminal accesses when receiving short messages and/or incoming calls (here, CID and LAC are used for description), and the time of receiving short messages and/or incoming calls, That is, the server uses the moving characteristics of the pseudo base station (movable, suddenly appearing and disappearing) to identify possible potential pseudo base stations.

First, the server can obtain the location information of the terminal and the base station information that the terminal accesses when receiving a short message or an incoming call according to the event information reported by multiple terminals: [lat, lng, date]={cid, lac; cid, lac… }. Obtain the location information of a group of terminals accessing the base station when each base station appears: [cid, lac, timestamp]={lat, lng; lat, lng; ...}.

The base station 1 can be used as an example for description. Suppose the information of this base station 1 is represented by [cid8, lac8], and the location information of the terminal accessing at the first time includes: [cid8, lac8, timestamp1]={lat1, lng1 ;lat5,lng5;lat6,lng6;lat9,lng9;lat10,lng10;lat12,lng12};

The location information of the terminal accessed at the second time includes: [cid8, lac8, timestamp2]={lat1, lng1; lat3, lng3; lat4, lng4; lat5, lng5; lat10, lng10; lat11, lng11};

The location information of the terminal accessed at the third time includes: [cid8, lac8, timestamp3]={lat1, lng1; lat3, lng3; lat4, lng4; lat5, lng5; lat9, lng9; lat12, lng12};

The location information of the terminal accessed at the fourth time includes: [cid8, lac8, timestamp4]={lat1, lng1; lat2, lng2; lat4, lng4; lat5, lng5; lat10, lng10; lat11, lng11}.

Secondly, the server can calculate the first center position of the group of terminals at the first time, the second center position of the group of terminals at the second time, the third center position of the group of terminals at the third time, and the third center position of the group of terminals at the third time. The fourth central position of this group of terminals at four times. Then, it can be considered that the first central position is the position of base station 1 at the first time, the second central position is the position of base station 1 at the second time, the third central position is the position of base station 1 at the third time, and the fourth central position is the position of base station 1 at the fourth time.

Finally, for the position of the base station 1 at different times, the deviation within a certain distance (for example, 500m) belongs to the normal range; the deviation above 500m can be considered as a mobile base station. Thereby, a group of information of a suspected mobile base station is obtained: MC={cid, lac; cid, lac; ...}.

Assuming that, after the above calculation, the absolute value of the difference between the positions of the base station 1 at different times exceeds 500m, then the base station 1 can be considered as a mobile base station. The above only takes the base station 1 as an example for description, and other base stations also have similar processing methods, which will not be repeated here.

On the basis of MC, the appearance time of the base station is compared again, and for the base station whose appearance time is shorter, for example, disappears in less than 1 day, the information of the suspicious base station is formed: SC={cid, lac; cid, lac; ...}.

Suppose, for the calculation of the position of base station 1, the above-mentioned first time, second time, third time and fourth time are on the same day, and this base station has never appeared before or after, then, this base station 1 has a high probability of being false base station. It should be understood that both MC and SC can be regarded as information of the pseudo base station, and can identify the suspicious probability as 100%.

It should be noted that, after the first center position is calculated above, it is also possible to exclude the terminal position that deviates from the first center position, and then calculate this group of terminals again (excluding the terminal position that deviates greatly from the first center position). The first target center position of the terminal); similarly, after calculating the second center position, it is also possible to exclude the terminal position that deviates from the second center position, and then calculate this group of terminals (excluding the second center position) again. The second target center position of the terminal with a larger deviation from the second center position); others can be processed similarly, and details are not repeated here. Because if the position of the terminal deviates too far from the first center position and the second center position, it means that the calculated center position has a large deviation from the position of the base station, which means that the reliability of the position of the base station is poor. Therefore, the terminal position with a large deviation can be excluded, and a calculation is performed again to represent the position of the base station, and the accuracy rate is relatively high. Here, the first target center position and the second target center position are used to represent the positions of the base station at different times. The subsequent calculation method is similar to the above description, and will not be repeated here.

It should also be noted that the server acquiring the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals includes but is not limited to the methods mentioned above. For example, if the information of the pseudo base station is obtained, the server can determine, according to the information of all base stations reported by multiple terminals, that the information of the pseudo base station is the rest, and the rest can be regarded as the information of the real base station; or the real base station is obtained. information, then the server can determine, according to the information of all base stations reported by multiple terminals, that in addition to the information of the real base station, the rest can be regarded as the information of the pseudo base station.

303. The server determines, according to the information of the real base station and the information of the pseudo base station, a target terminal of the plurality of terminals accessing the pseudo base station.

In the embodiment of the present application, for example, the information of the real base station is shown in Table 1 below:

Table 1

The information of the pseudo base station is shown in Table 2 below:

Table 2

The server determines, according to the information of the real base station and the information of the pseudo base station, the target terminal that accesses the pseudo base station among the multiple terminals, which may be determined to be accessed when the event occurs among the multiple terminals. The base station is the target terminal of the pseudo base station. Assuming that 100 terminals access the pseudo base station, the server can send the indication information of the pseudo base station to the 100 terminals.

304. The server sends the indication information of the pseudo base station to the target terminal.

Exemplarily, the server may send the indication information of the pseudo base station to the 100 terminals at the same time, or may send the indication information of the pseudo base station according to the priority of the terminals, which is not specifically limited here. It should be noted that, in practical applications, the server may also send indication information of the real base station to the terminal whose base station is the real base station when the event occurs among the multiple terminals.

305. The target terminal prompts the indication information of the pseudo base station.

In this embodiment of the present application, the target terminal may display the information of the event through the application interface corresponding to the event, and the information of the event may include the content of the short message and/or the caller number. The indication information that the target terminal prompts the pseudo base station may include but is not limited to the following implementations:

Manner 1: The terminal displays the indication information of the pseudo base station through text.

Manner 2: The terminal prompts the indication information of the pseudo base station by voice.

Manner 3: The terminal displays the indication information of the pseudo base station through a danger sign.

The target terminal may prompt the information of the pseudo base station through the application interface corresponding to the event. That is, the mobile phone can prompt the instruction information of the pseudo base station through the short message interface corresponding to the short message, and/or the incoming call interface corresponding to the incoming call, and/or voice. The target terminal here may refer to the above-mentioned 100 terminals, and one of them (such as a mobile phone) is used as an example for description.

In a possible implementation manner, the terminal may display the indication information of the pseudo base station through text. It is assumed that the mobile phone receives the short message content 11 displayed by the short message, and displays the instruction information of the pseudo base station through the text 21 on the short message interface. As shown in FIG. 4( c ), it is a schematic diagram of the mobile phone displaying the indication information of the pseudo base station through the short message interface. In Fig. 4(c), the indication information of the pseudo base station is a text indication of "suspected fraudulent short message". It is assumed that the mobile phone receives the caller ID 12 of the caller ID, and displays the instruction information of the pseudo base station through the text 21 on the caller interface. As shown in FIG. 4(d), it is another schematic diagram of the mobile phone displaying the indication information of the pseudo base station through the incoming call interface. In Fig. 4(d), the indication information of the pseudo base station is a text indication of "suspected fraudulent call". It should be noted that the text prompt may also be a prompt such as a high-risk short message or a high-risk call point, which is not specifically limited.

In another possible implementation manner, the terminal may prompt the indication information of the pseudo base station by voice. It is assumed that the mobile phone receives the short message content 11 displayed by the short message, and prompts the pseudo base station instruction information by voice 22 on the short message interface. As shown in FIG. 4( e ), it is a schematic diagram of the mobile phone performing voice reminder for the received short message according to the instruction information of the pseudo base station. In Figure 4(e), the indication information of the pseudo base station will trigger the preset voice function, and the mobile phone will play the voice (for example, the preset voice can be that this short message may be a fraudulent short message, etc. *The text messages sent by the number may be fraudulent text messages, etc.) to alert the user. It is assumed that the mobile phone receives the caller number 12 displayed on the caller ID, and prompts the pseudo base station instruction information by voice 22 on the caller interface. As shown in FIG. 4( f ), it is a schematic diagram of the mobile phone giving a voice reminder to the incoming call according to the instruction information of the pseudo base station. In Figure 4(f), the indication information of the pseudo base station will trigger the preset voice function, and the mobile phone will remind the user by playing the voice (for example, the preset voice can be that this number may be a fraudulent number, please answer carefully, etc.).

In another possible implementation manner, the terminal may prompt the indication information of the pseudo base station through a danger icon. It is assumed that the mobile phone receives the short message content 11 displayed by the short message, and prompts the instruction information of the pseudo base station through the danger icon 23 on the short message interface. As shown in FIG. 4( g ), it is a schematic diagram of the mobile phone reminding the received short message through the danger icon according to the instruction information of the pseudo base station. In Figure 4(g), the indication information of the pseudo base station will trigger a danger icon, and the mobile phone displays the danger icon through the SMS interface to remind the user. It is assumed that the mobile phone receives the caller number 12 displayed on the caller ID, and prompts the pseudo base station instruction information through the danger icon 23 on the caller interface. As shown in Figure 4(h), it is a schematic diagram of the mobile phone reminding the incoming call through the danger icon according to the instruction information of the pseudo base station. In Figure 4(h), the indication information of the pseudo base station will trigger the danger icon, and the mobile phone will display the danger icon through the incoming call interface to remind the user. It should be noted that the danger icons may include, but are not limited to, the prompts of triangles and exclamation marks shown in Figures 4(g) and 4(h), and may also directly be the prompts of triangle icons or exclamation mark icons or other danger prompts.

It should be noted that the prompt about the indication information of the pseudo base station includes, but is not limited to, the several implementation manners mentioned above, and may also be implemented in other manners, which are not specifically limited. For example: text + voice prompting method: as shown in Figure 4(i), it is a schematic diagram of the mobile phone prompting the received short message through text and voice according to the instruction information of the pseudo base station. As shown in FIG. 4(j), it is a schematic diagram of the mobile phone reminding the incoming call through text and voice according to the instruction information of the pseudo base station.

Prompt mode of text + danger icon: As shown in Figure 4(k), it is a schematic diagram of the mobile phone reminding the received short message through text and danger icon according to the instruction information of the pseudo base station. As shown in FIG. 4(1), it is a schematic diagram of the mobile phone reminding the incoming call through text and danger icons according to the instruction information of the pseudo base station.

Prompt mode of voice + danger icon: As shown in Figure 4(m), it is a schematic diagram of the mobile phone reminding the received short message through voice and danger icon according to the instruction information of the pseudo base station. As shown in Fig. 4(n), it is a schematic diagram of the mobile phone reminding the incoming call through voice and danger icon according to the instruction information of the pseudo base station.

In another possible implementation manner, for the short message, the terminal can automatically classify the short message into the junk short message list to prompt the indication information of the pseudo base station, as shown in Figure 4(o), for the mobile phone to automatically classify the short message into In the junk short message list to prompt the instruction information of the pseudo base station. For incoming calls, the terminal can prompt the pseudo base station instruction information by automatically rejecting the incoming call. It should be understood that on the above-mentioned text message interface or incoming call interface, for the indication information indicating the pseudo base station by text and the indication information indicating the pseudo base station by the icon, the implementation method may be in the form of a pop-up box, a floating form, or a bubble, etc., which is not specifically limited. . Steps 303-305 are optional steps.

In the embodiment of the present application, the server obtains the information of the real base station and the information of the pseudo base station according to the big data reported by multiple terminals, so the obtained information of the real base station and the information of the pseudo base station has a relatively high accuracy. That is, the server receives event information sent by multiple terminals, and the event information may include terminal identification, location information of the terminal, information of the base station accessed when the event occurs, and time when the event occurs. The server obtains the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals. The server may further determine the target terminal that accesses the pseudo base station among the multiple terminals according to the information of the real base station and the information of the pseudo base station; and send the indication information of the pseudo base station to the target terminal, so that the user can cause the event on the target terminal to cause Be vigilant and beware of being deceived.

As shown in FIG. 5 , it is a schematic diagram of another embodiment of the prompting method in the embodiment of the present application, including:

501. The server receives event information sent by multiple terminals.

502. The server acquires the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals.

503. The server determines, according to the information of the real base station and the information of the pseudo base station, a target terminal of the multiple terminals that accesses the pseudo base station.

504. The server sends the indication information of the pseudo base station to the target terminal.

505. The target terminal prompts the indication information of the pseudo base station.

In this embodiment of the present application, steps 501-505 are similar to steps 301-305 in the above-mentioned embodiment shown in FIG. 3 , and details are not repeated here.

506. The server marks the suspicious probability of the real base station and the fake base station.

In the embodiment of the present application, after acquiring the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals, the server may mark the suspicious probability of the real base station and the pseudo base station, for example, mark the suspicious probability of the real base station The probability is 0, and the suspicious probability of flagging a fake base station is 100%.

Example 1: As shown in Table 3 below, it is the correspondence between real base stations and suspicious probabilities in different areas.

table 3

Example 2: If both the suspicious base station and the mobile base station are considered to be pseudo base stations, as shown in Table 4 below, it is the corresponding relationship between the suspicious base station, the mobile base station and the suspicious probability.

suspicious base station suspicious probability mobile base station suspicious probability {cid8, lac8} 100% {cid12, lac12} 100% {cid15, lac15} 100% {cid8, lac8} 100% {cid19, lac19} 100% {cid19, lac19} 100% {cid20, lac20} 100% {cid20, lac20} 100% {cid15, lac15} 100% {cid36, lac36} 100% {cid40, lac40} 100%

Table 4

It should be noted that the mobile base station and the suspicious base station shown in Table 4 can be considered as pseudo base stations, but the suspicious probability that the suspicious base station is a pseudo base station may be higher. Because the mobile base station also exists in the operator, the suspected probability that the mobile base station is a pseudo base station is relatively low.

Example 3: The suspicious probability of other base stations other than the suspicious base station in the mobile base station can also be marked lower, as shown in Table 5 below, which is the corresponding relationship between the suspicious base station, the mobile base station and the suspicious probability.

suspicious base station suspicious probability mobile base station suspicious probability {cid8, lac8} 100% {cid12, lac12} 80% {cid15, lac15} 100% {cid8, lac8} 100% {cid19, lac19} 100% {cid19, lac19} 100% {cid20, lac20} 100% {cid20, lac20} 100% {cid15, lac15} 100% {cid36, lac36} 80% {cid40, lac40} 80%

table 5

It should be noted that the sequence of step 506 may be after step 502 and before step 507 .

507. The first target terminal receives the feedback information.

In this embodiment of the present application, the first target terminal may be one terminal in the above target terminals, or may be multiple terminals in the above target terminals, which may be specifically determined according to the actual situation. The feedback information is input information entered by the user as to whether the indication information that the base station accessed by the terminal when the event occurs is a pseudo base station is accurate.

After the first target terminal receives the indication information of the pseudo base station, the first target terminal will prompt the indication information of the pseudo base station. An example can be used to illustrate: as shown in Figure 6(a), it is a schematic diagram of the mobile phone displaying input feedback information on the SMS interface, and it can also display on the SMS interface "Please give feedback from the user, whether the SMS is a fraudulent SMS", The user can enter feedback information in the editable text box 31 . As shown in Figure 6(b), it is another schematic diagram of the mobile phone displaying input feedback information on the SMS interface, and the "Yes" and "No" signs 32 can also be displayed on the SMS interface, and the user directly clicks "Yes" or "No" ” logo can be used. Of course, the "ignored" logo can also be displayed on the SMS interface, or no text is entered, which means that the feedback information is meaningless and does not need to be reported to the server. After the user inputs feedback information in the text box or clicks the "Yes" or "No" sign, the terminal can receive the corresponding feedback information.

As shown in Figure 6(c), it is a schematic diagram of the mobile phone displaying input feedback information on the incoming call interface. The mobile phone displays “Please feedback from the user, whether the incoming call is a fraudulent incoming call” on the incoming call interface, and the user can edit the text in the editable text Block 31 enters feedback information. As shown in Figure 6(d), it is a schematic diagram of the mobile phone displaying input feedback information on the incoming call interface, and the "Yes" and "No" signs 32 can also be displayed on the incoming call interface, and the user directly clicks "Yes" or "No" 's identification. Of course, the "ignored" logo can also be displayed on the incoming call interface, or no text is entered, which means that the feedback information is meaningless and does not need to be reported to the server. From the point of view of convenience, the operation of clicking may be more convenient for the user. The input feedback information displayed on the incoming call interface may also be displayed after the user hangs up the call. After the user inputs feedback information in the text box or clicks the "Yes" or "No" sign, the terminal can receive the corresponding feedback information.

It should be noted that the schematic diagram of how the terminal displays the input feedback information may include but not limited to the above-mentioned several manners. The description about the feedback information input by the user may be that some users may have received a text message from this number or a call from this number before, and when they receive a call or text message from the same number again, they can determine whether it is a fraudulent text message or a fraudulent call. It may be through this call to determine whether it is a fraudulent call, so that the user can input corresponding feedback information. When any of the above-mentioned Fig. 6(a)-Fig. 6(d) shows that the input feedback information is explained by text prompting the instruction information of the pseudo base station, when the instruction information of the pseudo base station is prompted by voice or a danger icon prompts the pseudo base station instruction information , the schematic diagrams for displaying the input feedback information are similar to those in FIG. 6(a)-FIG. 6(d), which will not be repeated here.

508. The first target terminal sends the feedback information to the server.

In the embodiment of the present application, it is assumed that the server previously determined that there are 100 target terminals accessing the pseudo base station, and the server sends indication information of the pseudo base station to the 100 target terminals. However, only 50 of the 100 target terminals have received input information from the user indicating whether the base station accessed by the terminal when the event occurs is a pseudo base station is accurate. Then, the 50 target terminals can report the feedback information to the server. Assume that 45 users input "No" feedback information, and 5 users input "Yes" feedback information.

509. The server correspondingly modifies the suspicious probability of the pseudo base station according to the feedback information, and obtains the modified suspicious probability of the pseudo base station.

In the embodiment of the present application, it is assumed that the feedback information reported by the above-mentioned 50 target terminals is for the base station {cid15, lac15}, and the base station {cid15, lac15} corresponds to 45 "No" feedback information, 5 "Yes" feedback information ” feedback. Then, the server can determine that the base station {cid15, lac15} is not a pseudo base station with a 90% probability and a pseudo base station with a 10% probability. That is, correspondingly, the suspicious probability of the base station {cid15, lac15} can be modified to 10% in Table 4 and Table 5 above. When the suspicious probability is less than or equal to the suspicious probability threshold, the base station can be considered as a real base station. Here, it is assumed that the suspicious probability threshold is 20%. Then, the server can update the information of the base stations {cid15, lac15} to the information of the real base station. The area where base station {cid15, lac15} appears is [lat7, lng7], update the information of base station {cid15, lac15} to the above Table 3, delete the information of base station {cid15, lac15} in Table 4 and Table 5.

As shown in Table 6, the corresponding relationship between the information about the real base station and the suspicious probability of the updated Table 3 is as follows:

Table 6

As shown in Table 7, the updated Table 4 shows the correspondence between suspicious base stations, mobile base stations and suspicious probability, as follows:

suspicious base station suspicious probability mobile base station suspicious probability {cid8, lac8} 100% {cid12, lac12} 100% {cid19, lac19} 100% {cid8, lac8} 100% {cid20, lac20} 100% {cid19, lac19} 100% 100% {cid20, lac20} 100% {cid36, lac36} 100% {cid40, lac40} 100%

Table 7

As shown in Table 8, the updated Table 5 shows the correspondence between suspicious base stations, mobile base stations and suspicious probability, as follows:

suspicious base station suspicious probability mobile base station suspicious probability {cid8, lac8} 100% {cid12, lac12} 80% {cid19, lac19} 100% {cid8, lac8} 100% {cid20, lac20} 100% {cid19, lac19} 100% {cid20, lac20} 100% {cid36, lac36} 80% {cid40, lac40} 80%

Table 8

It should be noted that, in practical applications, the feedback information received by the server may be directed to the same base station or may be directed to different base stations, and the manner of modifying the suspicious probability is similar to the above, and will not be repeated here. Moreover, updating the information of the real base station and the information of the pseudo base station includes, but is not limited to, other implementation manners. For example, for the same base station, in the feedback information received by the server in the first period of time, there are two "yes" Feedback information, 6 "No" feedback messages; 1 "Yes" feedback message and 8 "No" feedback messages among the feedback messages received in the second duration; Received in the third duration In the feedback information, there are 0 "Yes" feedback information and 10 "No" feedback information; maybe after these 3 revisions, the suspicious probability of the base station has not been lower than the suspicious probability threshold 20%, but the server according to the received It is found that the number of feedback "Yes" feedback information is getting smaller and smaller, and the number of feedback "No" feedback information is increasing, then it can be considered that the base station is not a pseudo base station. The base station is updated in the information of the real base station.

In the embodiment of the present application, the server obtains the information of the real base station and the information of the pseudo base station according to the big data reported by multiple terminals, so the obtained information of the real base station and the information of the pseudo base station has a relatively high accuracy. That is, the server receives event information sent by multiple terminals, and the event information may include terminal identification, location information of the terminal, information of the base station accessed when the event occurs, and time when the event occurs. The server obtains the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals. The server may also determine, according to the determined information of the real base station and the information of the pseudo base station, the target terminal accessing the pseudo base station among the multiple terminals; The incident aroused vigilance, beware of being deceived.

Further, the server can also use the characteristics of the movement of the pseudo base station and the feedback information of the terminal to modify the suspicious probability of the pseudo base station, and update the information of the real base station and the information of the pseudo base station, so that the server receives the first event reported by the first terminal next time. When the information of the real base station is updated, it can be determined whether the first base station accessed by the terminal when the first event occurs is a pseudo base station according to the updated information of the real base station and the information of the pseudo base station. The information judged results are more accurate.

The information of the target real base station and the target pseudo base station includes but is not limited to information such as cid, lac, signal strength, and the difference between the acquisition time and the reporting time. The collection time refers to the time when the corresponding terminal occurs, and the reporting time refers to the time when the terminal sends event information to the server. The collection time may be the same as the reporting time, or the reporting time may be after the collection time.

711. The server performs model training according to the information of the target pseudo base station and the information of the target real base station, and obtains a reference weight of each feature included in the information of the base station.

In the embodiment of the present application, the server may use other algorithms such as the Logistics algorithm to perform model training according to the information of the target pseudo base station and the information of the target real base station, and obtain the reference weight of each feature included in the information of the base station. For example: cid=w1, lac=w2, signal strength=w3, time difference=w4…

For a schematic diagram of the first terminal receiving the first short message or the first incoming call, reference may be made to the above-mentioned FIG. 4( a ) and FIG. 4( b ), which will not be repeated here.

It should be noted that step 712 may be between steps 702-713.

713. The first terminal sends the information of the first event to the server.

In this embodiment of the present application, the server receives the information of the first event sent by the first terminal. It should be noted that the first terminal may be a terminal among the aforementioned multiple terminals, or may be another terminal newly accessed outside the multiple terminals. Moreover, the number represented by the first terminal is not limited, and may refer to one terminal, or may refer to multiple terminals. In the following description, the first terminal is the mobile phone 1 as an example for description. That is, the server receives the information of the first event sent by the mobile phone 1, and the information of the first event includes the identification of the mobile phone 1, the location information of the mobile phone 1, and the information of the first base station accessed when the first event occurs. , the time when the first event occurs.

Wherein, the location information of the mobile phone 1 can be obtained by using the global positioning system (Global Positioning System, GPS), or the longitude and latitude calculated by using the network. ) physical address of the wireless access point (Basic Service Setidentifier, BSSID)/identity of the wireless access point or service set identifier (Service Set Identifier, SSID)/Medium Access Control address (Medium Access Control address, MAC addr)/ Network ID (NetworkID), the currently scanned WiFi SSID and other information.

714. The server determines whether the first base station is a pseudo base station.

In the embodiment of the present application, the authenticity determination of the first base station can be implemented in several different ways, which are described below:

The first way: the server searches and determines the information of the real base station and the information of the pseudo base station stored in the database.

If step 712 is after step 702 and before step 709, the server may search the information of the real base station and the information of the pseudo base station obtained according to the information of events sent by multiple terminals. If the information of the first base station is in the information of the pseudo base station If the information of the first base station is in the information of the real base station, it means that the first base station is a real base station, and the server may not send the information of the pseudo base station to the mobile phone 1. 1 Send the indication information of the real base station.

If step 712 is after step 709 and before step 713, the server can search in the updated real base station information and pseudo base station information, if the first base station information is in the updated pseudo base station information, it is considered that the first base station information If a base station is a pseudo base station, the server can send the indication information of the pseudo base station to the mobile phone 1. If the information of the first base station is in the updated information of the real base station, it means that the first base station is a real base station, and the server may not send it to the mobile phone 1. Indication information of the real base station.

The second way: if step 712 is after step 702 and before step 709, the server can first search the information of the first base station in the information of the pseudo base station and the information of the real pseudo base station saved in the database. Alternatively, if step 712 is after step 709 and before step 713, the server may first search for the information of the first base station in the updated real base station information and the updated pseudo base station information saved in the database.

If the information of the first base station is not found, the server may determine the target probability of the first base station according to the information of the first event and the reference weight of each feature included in the information of the base station. The server determines the target suspicious probability of the first base station Rate=sum (feature*weight)=cid*w1+lac*w2+signal strength*w3+time difference*w4+…. If the target probability is less than or equal to the fifth threshold, the server determines that the first station is a pseudo base station.

It should be noted that the target probability range calculated according to the reference weight is between 0 and 1, and those close to 1 can be regarded as real base stations, and those close to 0 can be regarded as pseudo base stations. Assuming that the target probability calculated here is 0.8, the fifth threshold can be set to 0.6, and 0.8 is greater than 0.6, so the server determines that the first base station is a real base station. Assuming that the target probability calculated here is 0.3, the fifth threshold may be set to 0.6, and 0.3 is less than 0.6, so the server determines that the first base station is a pseudo base station.

The third manner: the server directly determines the target probability of the first base station according to the information of the first event and the reference weight of each feature included in the information of the base station. That is, the server determines the target suspicious probability of the first base station Rate=sum (feature*weight)=cid*w1+lac*w2+signal strength*w3+time difference*w4+…. If the target probability is less than or equal to the fifth threshold, the server determines that the first base station is a pseudo base station.

715. If the first base station is a pseudo base station, the server sends the indication information of the pseudo base station to the first terminal.

In this embodiment of the present application, if it is determined that the first base station is a pseudo base station through any of the methods for determining the authenticity of the first base station described in step 714, the server sends the pseudo base station to the first terminal instruction information.

716. The first terminal prompts the indication information of the pseudo base station.

Here, the manner in which the first terminal prompts the indication information of the pseudo base station may refer to the prompt manner in any of the above-mentioned Fig. 4(c)-Fig.

In the embodiment of the present application, the server obtains the information of the real base station and the information of the pseudo base station according to the big data reported by multiple terminals, so the obtained information of the real base station and the information of the pseudo base station has a relatively high accuracy. That is, the server receives event information sent by multiple terminals, and the event information may include terminal identification, location information of the terminal, information of the base station accessed when the event occurs, and time when the event occurs. The server determines the information of the real base station and the information of the pseudo base station according to the information of the events sent by the multiple terminals. The server may also determine, according to the determined information of the real base station and the information of the pseudo base station, the target terminal accessing the pseudo base station among the multiple terminals; The first incident aroused vigilance, beware of being deceived.

Further, the server can also use the characteristics of the movement of the pseudo base station and the feedback information of the terminal to modify the suspicious probability of the pseudo base station, and update the information of the real base station and the information of the pseudo base station, so that the server receives the first event reported by the first terminal next time. When the information of the real base station is updated, it can be determined whether the first base station accessed by the terminal when the first event occurs is a pseudo base station according to the updated information of the real base station and the information of the pseudo base station. The information judged results are more accurate.

Further, the server can also select the information of a batch of base stations with the highest suspicious probability as positive examples, and the information of the base stations with the lowest suspicious probability as negative examples, according to the suspicious probability corresponding to the information of the real base station and the information of the pseudo base station, and perform model training. , to obtain the reference weight of each feature included in the information of the base station. These reference weights can be used for the next time the server receives the information of the first event reported by the first terminal, according to the reference weights of each feature and the information of the first base station, to calculate the information of the first base station accessed when the first event occurs. target probability. If the target probability is greater than the preset threshold, the server determines that the first base station is a real base station; if the target probability is less than or equal to the preset threshold, the server determines that the first base station is a pseudo base station, and the server sends indication information of the pseudo base station to the terminal. In this way, the server can calculate whether the access of the first terminal newly received by the server when the first event occurs is a pseudo base station according to the reference weight of each feature included in the information of the base station, which provides another way of determining the pseudo base station. , which increases the feasibility of the scheme.

On the other hand, according to the information of events reported by a large number of terminals and the feedback information of users, the suspicious probability of real base stations and pseudo base stations can be continuously learned, optimized and corrected, which will greatly improve the accuracy of judgment; "Recognition method" can only be compared and analyzed with the operator's existing base station data, and has a high accuracy rate in the case of judging mobile base stations. The server performs model training in real time according to the information of the target real base station and the information of the target pseudo base station, which can ensure the accuracy and real-time performance of the identification, and can discover new pseudo base stations in time; it can also identify the pseudo base station according to the big data technology. Motion trajectory, which can more effectively prevent fake base station fraud or even capture fake base station.
