Description

Prompt method, terminal and server

This application claims priority to the Chinese Patent Application, filed on Jan. 22, 2017, the number of which is hereby incorporated by reference. In the application.

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 many telecom fraud technologies, committing crimes through illegal base stations or pseudo-base stations has become the mainstream means. These pseudo base stations can be disguised as carrier's base stations, and fake other people's numbers to send fraudulent text messages. Based on the short message sent by the pseudo base station, it is very confusing because the number can be forged, and it is difficult for the terminal user to distinguish between true and false.

In the prior art, a method of generally identifying a pseudo base station is a method of identifying a pseudo base station by comparing a base station characteristic parameter with a terminal and a method of identifying a pseudo base station based on a base station position. The method for identifying a pseudo base station by comparing the characteristics of the base station with the terminal is: the terminal parses the characteristic parameter of the base station, and matches the locally preset feature parameter database, and if it is 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 blocked from the terminal. However, the decision logic relies entirely on the terminal and cannot be upgraded. With the development of the pseudo base station technology, some characteristic parameters can also be adjusted, but the terminal cannot be obtained dynamically, which easily leads to misjudgment.

The method for identifying the pseudo base station based on the location of the base station is: when the terminal receives the notification type short message, the short message and the terminal location information are reported to the server. The server performs calculation based on the information reported by a large number of terminals, obtains the base station information in a certain area, and then compares with the location in the carrier base station library, and is not considered as a pseudo base station in the carrier base station library. However, such a judgment method only has a risk for judging a notification type message, and the pseudo base station can construct an arbitrary number, so the sent short messages are not necessarily notification type short messages; the operator itself also has a mobile base station, which is aligned from the position alone. It is not completely reliable; in addition, the location of the base station reported by the terminal is obtained by algorithm calculation, and there is an error in itself.

detailed description

The technical solutions in the embodiments of the present application are described below with reference to the accompanying drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present application without creative efforts are within the scope of the present application.

The method for identifying a pseudo base station by using a terminal to compare base station characteristic parameters is as follows: when the terminal accesses the base station, parsing characteristic parameters of the base station, including a cell identifier or a cell identification (CID) called a base station, Location area code (LAC) and system information. The feature parameters are then matched to a locally preset parameter library, which is considered a legitimate base station if it is within the legal range. Otherwise, it is considered to be a pseudo base station, and the pseudo base station is directly blocked from the terminal. The judgment logic of the method is directly preset on the terminal chip, and the terminal device can be directly shielded from accessing the base station after the judgment. However, the decision logic relies entirely on the terminal and cannot be upgraded. With pseudo base station technology Some characteristic parameters of the development of the technique can also be adjusted, but the terminal cannot be obtained dynamically, which is easy to cause misjudgment.

The method for identifying the pseudo base station based on the location of the base station is that the notification is only for the notification type message, and the pseudo base station can construct any number not necessarily the notification type short message; the operator itself also has the mobile base station, and the position comparison is not It is completely reliable; in addition, the location of the base station reported by the device side is obtained by 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 the judgment caused by the failure of the local parameter database to be updated in time, and the judgment accuracy rate caused by the source of the data report being limited to the notification type short message and the operator mobile base station when using the server for judgment. .

The communication system framework diagram applied in the embodiment of the present application is as shown in FIG. 1, and the communication system may include a terminal and a server. As shown in FIG. 2 , a schematic diagram of a scenario applied by an embodiment of the present application, a legal base station that can be accessed by a terminal in the A area has a base station 2, and a correct base station that can be accessed in the B area has a

base station

2, 3, and 4.

In the embodiment of the present application, the server may receive the information of the event reported by the terminal, and the information of the event may include the identifier of the terminal, the location information of the terminal, the information of the base station accessed when the event occurs, and the time when the event occurs. The event may be receiving a text message or receiving an incoming call. And obtaining, according to the information about the event reported by the plurality of terminals, the information of the real base station and the information of the pseudo base station; the server determining, according to the information of the real base station and the information of the pseudo base station, the access pseudo in the large number of terminals. a target terminal of the base station; the server transmitting 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 event information, the more accurate the result determined by the server is. The server may further determine, according to the determined information of the real base station and the information of the pseudo base station, the target terminal in which the access base station is the pseudo base station, and send the indication information of the pseudo base station to the target terminal, so that the user occurs on the terminal. The incident caused vigilance and was carefully deceived.

In the embodiment of the present application, the server may further improve the suspicious probability of the pseudo base station, update the information of the real base station, and the information of the pseudo base station by using the characteristics of the pseudo base station movement, combined with the feedback information of the terminal, so that the server receives the first terminal next time. When the information of the first event is reported, the information about the real base station and the information of the pseudo base station may be used to determine whether the first base station accessed by the terminal when the first event occurs is a pseudo base station, such that the real base station according to the real-time update The information and the information of the pseudo base station determine the accuracy of the result.

In the embodiment of the present application, the server may further select, according to the suspicious probability corresponding to the information of the real base station and the information of the pseudo base station, the information of the base station with the highest suspicious probability as the positive example, and the information of the base station with the lowest suspicious probability as the negative example. Model training is performed to obtain reference weights of respective features included in the information of each base station. The reference weights of the respective features may be used when the server receives the information of the first event reported by the first terminal, and according to the reference weight of each feature and the information of the first event, calculate the access time 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 the 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 newly received terminal of the server is a pseudo base station according to the reference weight of each feature and the information of the first event, and provide another method for determining the pseudo base station. The implementation method increases the feasibility of the scheme.

The following is a specific description of the server receiving the multiple terminal reporting information in the embodiment of the present application. As shown in FIG. 3, it is a schematic diagram of an embodiment of a prompting method in an embodiment of the present application, including:

301. The server receives information about events sent by multiple terminals.

In the embodiment of the present application, before the server receives the information of the event sent by the multiple terminals, the terminal generates a detection event and collects information about the event, where the information of the event may include the terminal identifier (International Mobile Equipment Identity, The IMEI), the location information of the terminal, the information of the base station accessed when the event occurs, and the time when the event occurs, the time at which the event occurs may also be referred to as a timestamp. The terminal sends the information of the event to the server, it being understood that the event may include receiving a text 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 may be any terminal device including a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), an in-vehicle computer, etc. In the following example, the terminal may be a mobile phone. The example is explained. As shown in FIG. 4( a ), a schematic diagram of the mobile phone receiving the short message interface display. As shown in FIG. 4(b), a schematic diagram of receiving an incoming call interface for a mobile phone.

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

It should be understood that the information of the base stations that are accessed when multiple terminals generate events may be the same or different, and the time of occurrence of the events may be the same or different. It is also possible that the same terminal transmits 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 event actually collected by the terminal.

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

The server acquires information of the real base station and information of the pseudo base station according to the information of the event sent by the multiple terminals. The server can obtain information of the real base station and information of the pseudo base station by calculation of big data. For an explanation of the information of events sent by multiple terminals, the following examples are given:

For example, in a possible implementation manner, the server may set a quantity threshold, and when the number of terminals receiving the information of the sending event exceeds the quantity threshold, the server may obtain the real information according to the information of the event sent by the terminal exceeding the quantity threshold. Information of the base station and information of the pseudo base station.

In another possible implementation manner, the server may also set a specific threshold, which is the number of information for the event, that is, when the server receives information of an event exceeding a certain threshold, the server may The information of the event of the threshold acquires information of the real base station and information of the pseudo base station.

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

The server may obtain information of the real base station and information of the pseudo base station according to the information of the event sent by the multiple terminals in multiple manners. The following examples will be explained separately:

The server may obtain the information of the real base station according to the information of the event sent by the multiple terminals, and may include:

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

Example 1: The server 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), and the base station information that the terminal accesses when receiving the short message and/or the incoming call ( Here, the CID and LAC are used to describe the time of receiving the short message and/or the incoming call, or the base station information currently accessed by the terminal, and the adjacent CID information to determine the information of the real base station.

First, the geographic location takes a certain degree of computational accuracy (such as limiting the latitude and longitude decimal places, such as to 5 decimal places), combined with the data collection date, that is, longitude (lng), latitude (latitude, lat), date ( Date), then, at this time you can get a set of data about longitude, latitude, date [lat, lng, date] = {cid, lac; cid, lac; ...}; need to be explained, here because of lat, lng, The actual value of the date is different, you can get multiple sets of data about longitude, latitude, and date.

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 foregoing is only exemplified by these groups of data. In practical applications, the number is much more than the above-mentioned groups of data, because a small amount of data, the determined result is not much reference, this The embodiment is a solution proposed to improve the accuracy of the acquired pseudo base station. Therefore, the more data, the more accurate the determined result. Of course, the processing of these data needs to be within the load range of the server.

Secondly, the server further combines the data according to the latitude and longitude according to the obtained data about the longitude, latitude and date. During the merging process, the base station with unstable access occurs in consecutive days (for example, only one day of access occurs in a certain area) The base station is culled, and data about longitude and latitude [lat, lng]={cid, lac; cid, lac...} can be obtained, that is, the base station accessing in the range of [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 is merged. There are [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}, this information is the information for screening the base station.

Finally, the server gets a set of information data for screening the base station [lat, lng] = {cid, lac; cid, lac...}, then CC = [lat, lng] = {cid, lac; cid, lac...}, CC Indicates 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 region [lat2, lng1], the real base station information includes {cid8, lac8; cid5, lac5; cid6, lac6}; , lng2] In this area, the real base station information includes {cid5, lac5; cid6, lac6; cid7, lac7}.

The server may obtain the information of the pseudo base station according to the information of the event sent by the multiple terminals, and may include:

Determining, by the server, location information of the terminal that the target base station accesses at the first time according to the location information of the terminal that is sent by the multiple terminals, the information of the base station that is accessed when the event occurs, and the time when the event occurs. The location information of the terminal accessed at the second time, the target base station is any base station that is accessed when the multiple terminals generate the event; the server is according to the terminal that the target base station accesses at the first time The location information is calculated, the first central location of the accessed terminal is calculated, and the second central location of the accessed terminal is calculated according to the location information of the terminal accessed by the target base station at the second time; the server determines the Determining, by the first central location, a first location of the target base station, determining that the second central location is a second location of the target base station; and determining an absolute value of a difference between the first location and the second location If the value 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 (here described by CID and LAC) when the terminal receives the short message and/or the incoming call, and the time of receiving the short message and/or the incoming call. That is, the server uses the characteristics of the pseudo base station to move (movable, suddenly appears and disappears), and identifies 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 the short message or the incoming call according to the information of the event reported by the multiple terminals: [lat, lng, date]={cid,lac;cid,lac... }. Obtaining location information of a group of terminals accessing the base station when each base station occurs: [cid, lac, timestamp] = {lat, lng; lat, lng; ...}.

The base station 1 can be taken as an example for description. It is assumed that the information of the base station 1 is represented by [cid8, lac8], and the location information of the terminal accessed 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 central location of the set of terminals at the first time, the second central location of the set of terminals at the second time, and the third central location of the set of terminals at the third time, at the third The fourth central position of this group of terminals in four time. Then, the first central location can be considered to be the location of the base station 1 at the first time, the second central location is the location of the base station 1 at the second time, and the third central location is the location of the base station 1 at the third time, the fourth central location It is the position of the 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, 500 m) belongs to the normal range; the deviation of 500 m or more can be considered as the mobile base station. Thereby obtaining a set of information of a suspected mobile base station: MC = {cid, lac; cid, lac; ...}.

It is assumed that, after the above calculation, the absolute value of the difference between the bits of the base station 1 at different times exceeds 500 m, then the base station 1 can be considered as the mobile base station. The above description is only taking the base station 1 as an example, and other base stations are similar processing methods, and details are not described herein again.

On the basis of the MC, the time of occurrence of the base station is again compared, and the information of the suspicious base station is formed for the base station that disappears for a short time, for example, less than one day: SC={cid, lac; cid, lac; .

It is assumed that, for the calculation of the base station 1 bit, the first time, the second time, the third time and the fourth time are not present on the same day, before or after the base station, then the base station 1 has a high probability Pseudo base station. It should be understood that both MC and SC can be considered 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 计算 is calculated above, the terminal position 偏离 which is larger than the first center position 排除 can be excluded, and the group terminal is calculated again (excluding the deviation from the first center) The first target center position of the larger terminal); similarly, after calculating the second center position, the terminal position that deviates from the second center position can be excluded, and then calculated. The second target center position of this group of terminals (excluding the terminal that is larger than the second center position) is excluded; the others can be similarly processed, and will not be described here. Because if the position of the terminal is too far from the first center position 第二 and the second center position ,, it means that the calculated center position 臵 has a large deviation from the position of the base station, and is used to indicate the position of the base station. The reliability is poor. Therefore, the terminal position with large deviation can be eliminated, and then a calculation is performed to indicate the position of the base station, and the accuracy is relatively high. Here, the first target center position 臵 and the second target center position 臵 are used to indicate the position of the base station at different times. The subsequent calculation method is similar to the above description, and details are not described herein again.

It should be noted that the information of the real base station and the information of the pseudo base station are obtained by the server according to the information of the events sent by the multiple terminals, including but not limited to the above-mentioned methods. For example, if the information of the pseudo base station is obtained, the server may determine the information of the pseudo base station according to the information of all the base stations reported by the multiple terminals, and the remaining information may be regarded as the information of the real base station; The information can be determined by the server according to the information of all the base stations reported by the multiple terminals, except for the information of the real base station, and the rest can be regarded as the information of the pseudo base station.

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

In the embodiment of the present application, the information of the real base station is as follows:

区域region	真实基站Real base station
[lat1，lng1][lat1,lng1]	{cid1，lac1；cid2，lac2；cid3，lac3}{cid1, lac1; cid2, lac2; cid3, lac3}
[lat1，lng2][lat1,lng2]	{cid1，lac1；cid2，lac2；cid3，lac3；cid4，lac4}{cid1, lac1; cid2, lac2; cid3, lac3; cid4, lac4}
[lat2，lng1][lat2,lng1]	{cid8，lac8；cid5，lac5；cid6，lac6}{cid8, lac8; cid5, lac5; cid6, lac6}
[lat2，lng2][lat2,lng2]	{cid5，lac5；cid6，lac6；cid7，lac7}{cid5, lac5; cid6, lac6; cid7, lac7}

Table 1

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

Table 2

Determining, by the server, the target terminal that accesses the pseudo base station in the multiple terminals according to the information of the real base station and the information of the pseudo base station, where the server may determine that the event occurs when the event occurs in the multiple terminals. The base station is the target terminal of the pseudo base station. If 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.

For example, the indication information that the server sends the pseudo base station to the 100 terminals may be sent at the same time, and the indication information of the pseudo base station may be sent according to the priority of the terminal, which is not limited herein. It should be noted that, in an actual application, the server may also send the indication information of the real base station to the terminal that is accessed by the base station that is accessed when the event occurs in the multiple terminals.

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

In the embodiment of the present application, the target terminal may display the information of the event by using an application interface corresponding to the event, where the information of the event may include a short message content and/or an incoming call number. The indication information that the target terminal prompts the pseudo base station may include, but is not limited to, the following implementation manners:

Manner 1: The terminal displays the indication information of the pseudo base station by 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 by using a hazard identifier.

The information of the pseudo base station can be prompted by the application interface corresponding to the event on the target terminal. That is, the mobile phone may prompt the instruction information of the pseudo base station by using an SMS interface corresponding to the short message, and/or an incoming call interface corresponding to the incoming call, and/or voice. The target terminal here may refer to the above 100 terminals, and one of them is taken as an example (such as a mobile phone) for explanation.

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

In another possible implementation manner, the terminal may prompt the indication information of the pseudo base station by voice. Assume that the mobile phone receives the short message content 11 displayed by the short message, and prompts the indication information of the pseudo base station through the voice 22 on the short message interface. As shown in FIG. 4(e), it is a schematic diagram of the mobile phone performing voice prompting on the received short message according to the indication information of the pseudo base station. In FIG. 4(e), the indication information of the pseudo base station triggers the preset voice function, and the mobile phone plays the voice (for example, the preset voice may be that the short message may be a fraudulent message, etc., or * The text message sent by the number may be a fraudulent message, etc.) to remind the user. Assume that the mobile phone receives the caller ID 12 of the caller ID and prompts the indication information of the pseudo base station through the voice 22 on the incoming call interface. As shown in FIG. 4(f), it is a schematic diagram of the mobile phone performing voice reminding on the received incoming call according to the indication information of the pseudo base station. In FIG. 4(f), the indication information of the pseudo base station triggers the preset voice function, and the mobile phone reminds the user by playing the voice (for example, the preset voice may be that the number may be a fraudulent number, please be careful to answer, etc.).

In another possible implementation manner, the terminal may prompt the indication information of the pseudo base station by using a danger icon. It is assumed that the mobile phone receives the short message content 11 displayed by the short message, and prompts the indication 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 by the danger icon according to the indication information of the pseudo base station. In FIG. 4(g), the indication information of the pseudo base station triggers a danger icon, and the mobile phone displays a danger icon through the short message interface to remind the user. Assume that the mobile phone receives the caller ID 12 of the caller ID and prompts the indication information of the pseudo base station through the danger icon 23 on the incoming call interface. As shown in FIG. 4(h), it is a schematic diagram of the mobile phone reminding the received incoming call by the danger icon according to the indication information of the pseudo base station. In FIG. 4(h), the indication information of the pseudo base station triggers a danger icon, and the mobile phone displays a danger icon through the incoming call interface to remind the user. It should be noted that the danger icon may include, but is not limited to, the hint of the triangle plus the exclamation mark shown in FIG. 4(g) and 4(h), and may also be a prompt of the triangle icon or an exclamation point icon or other dangerous prompt manner.

It should be noted that the prompting information about the indication information of the pseudo base station includes, but is not limited to, the foregoing implementation manners, and may be implemented in other manners, and is not limited thereto. For example, the text + voice prompt mode: as shown in FIG. 4( i ), is a schematic diagram of the mobile phone reminding the received short message by 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 received incoming call by text and voice according to the indication information of the pseudo base station.

The prompt mode of the text + danger icon: as shown in FIG. 4(k), is a schematic diagram of the mobile phone reminding the received short message by the text and the danger icon according to the instruction information of the pseudo base station. As shown in FIG. 4(l), it is a schematic diagram for the mobile phone to remind the received incoming call by the text and the danger icon according to the indication information of the pseudo base station.

The prompt mode of the voice + danger icon: as shown in FIG. 4(m), is a schematic diagram of the mobile phone reminding the received short message by using the voice and danger icons according to the indication information of the pseudo base station. As shown in FIG. 4(n), it is a schematic diagram for the mobile phone to remind the received incoming call by voice and danger icons according to the indication information of the pseudo base station.

In another possible implementation manner, for the short message, the terminal may automatically classify the short message into the spam short message list to prompt the indication information of the pseudo base station, as shown in FIG. 4( o ), automatically classify the short message for the mobile phone to The indication of the pseudo base station is prompted in the spam list. For the incoming call, the terminal may prompt the indication information of the pseudo base station by automatically rejecting the incoming call, as shown in FIG. 4(p), which is a schematic diagram of the mobile phone automatically rejecting the indication information of the incoming call prompting pseudo base station.

It should be understood that, in the foregoing short message interface or the incoming call interface, the indication information of the text prompting pseudo base station and the indication information of the icon prompting the pseudo base station may be implemented in the form of a bullet frame, a suspended form, or a bubble, and the like is not limited. . Steps 303-305 are optional steps.

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 information about events sent by multiple terminals.

502. The server acquires information about a real base station and information of a pseudo base station according to information about 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 that accesses the pseudo base station among the multiple terminals.

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

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

In the embodiment of the present application, the steps 501-505 are similar to the steps 301-305 in the foregoing embodiment shown in FIG. 3, and details are not described herein again.

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

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

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

区域region	真实基站Real base station	可疑概率Suspicious probability

Table 4

It should be noted that the mobile base station and the suspicious base station shown in Table 4 can be regarded as pseudo base stations, but the suspicious probability that the suspicious base station is a pseudo base station may be higher. Since there are mobile base stations among operators, the suspicious probability that the mobile base station is a pseudo base station is relatively low.

Example 3: The suspicious probability flag of other base stations other than the suspicious base station in the mobile base station may also be marked lower, as shown in Table 5 below, as a correspondence relationship between the suspicious base station, the mobile base station, and the suspicious probability.

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

507. The first target terminal receives the feedback information.

In the embodiment of the present application, the first target terminal may be one of the target terminals, or may be a plurality of terminals in the target terminal, and may be determined according to actual conditions. The feedback information is input information input by the user 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 may prompt the indication information of the pseudo base station. The following can be illustrated by an example: as shown in FIG. 6( a ), a schematic diagram for displaying the input feedback information on the short message interface of the mobile phone, and also displaying “Please feedback the user whether the short message is a fraudulent short message” on the short message interface. The user can input feedback information in an editable text box 31. As shown in FIG. 6(b), another schematic diagram for displaying the input feedback information on the short message interface of the mobile phone may also display the “Yes” and “No” identifiers 32 on the short message interface, and the user directly clicks “Yes” or “No”. "The logo can be. Of course, the SMS interface can also display the "ignore" logo, or if there is no input text, then the feedback information is meaningless and need not be reported to the server. When the user inputs the feedback information in the text box or clicks the "Yes" or "No" identifier, the terminal can receive the corresponding feedback information.

As shown in FIG. 6(c), a schematic diagram for displaying the input feedback information on the incoming call interface of the mobile phone, the mobile phone displays “Please feedback the user if the incoming call is a fraudulent call” on the incoming call interface, and the user can edit the text. Block 31 inputs feedback information. As shown in FIG. 6(d), a schematic diagram for displaying the input feedback information on the incoming call interface of the mobile phone may also display the “Yes” and “No” identifiers 32 on the incoming call interface, and the user directly clicks “Yes” or “No”. The logo can be. Of course, the “Ignore” logo can also be displayed on the incoming call interface, or if there is no input text, then the feedback information is meaningless and need not be reported to the server. From a convenience point of view, the click operation may be more convenient for the user. Displaying the input feedback information on the incoming call interface can also be displayed after the user hangs up the phone. When the user inputs the feedback information in the text box or clicks the "Yes" or "No" identifier, 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 is not limited to, the foregoing manners. The description about the user inputting the feedback information may be that some users may have received the short message sent by the number or received the incoming call of the number, and when receiving the incoming call or the short message sent by the same number again, it may determine whether it is a fraudulent short message or a fraudulent call. It can be determined by this call whether it is a fraudulent call, so that the user can input corresponding feedback information. In the above-mentioned FIG. 6 (a) - FIG. 6 (d), the input feedback information is described by the instruction information of the character prompting pseudo base station, and the indication information of the pseudo base station or the danger icon is used to prompt the indication information of the pseudo base station. The schematic diagram showing the input feedback information is similar to FIG. 6(a) to FIG. 6(d), and will not be described again 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 determines that there are 100 target terminals accessing the pseudo base station, and the server sends the 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 that is correct when the base station accessed by the terminal when the event occurs is the pseudo base station. Then, the 50 target terminals can report the feedback information to the server. Assume that there are 45 users inputting "no" feedback information, and five users inputting "yes" feedback information.

509. The server, according to the feedback information, correspondingly modify a suspicious probability of the pseudo base station, to obtain a 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 50 target terminals is 45 "No" feedback information corresponding to the base station {cid15, lac15}, and the base station {cid15, lac15}, 5 "is Feedback. Then, the server can determine that the base station {cid15, lac15} has a 90% probability that it is not a pseudo base station, and the 10% probability is a pseudo base station. That is, the corresponding suspicious probability of the base station {cid15, lac15} can be modified to 10% in the above Table 4 and Table 5. 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. If the suspicious probability threshold is 20%, then the server can update the information of the base station {cid15, lac15} to the information of the real base station, assuming The area where the base station {cid15, lac15} appears is [lat7, lng7], the information of the base station {cid15, lac15} is updated to the above table 3, and the information of the base station {cid15, lac15} is deleted in Table 4 and Table 5.

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

区域region	真实基站Real base station	可疑概率Suspicious probability
[lat1，lng1][lat1,lng1]	{cid1，lac1；cid2，lac2；cid3，lac3}{cid1, lac1; cid2, lac2; cid3, lac3}	00

[lat7，lng7][lat7,lng7]	{cid15，lac15}{cid15,lac15}	10％10%

As shown in Table 7, for the updated table 4, the relationship between the suspicious base station, the mobile base station, and the suspicious probability is as follows:

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

Table 8

It should be noted that, in actual applications, the feedback information received by the server may be for the same base station, or may be for different base stations, and the manner of modifying the suspicious probability is similar to the foregoing, and details are not described herein again. Moreover, the information of the real base station and the information of the pseudo base station are updated, but are not limited to other implementation manners. For example, for the same base station, there are two “yes” of the feedback information received by the server in the first time period. Feedback information, 6 "no" feedback information; in the feedback information received within the second duration, there is 1 "yes" feedback information, 8 "no" feedback information; received in the third time period In the feedback information, there are 0 "yes" feedback information and 10 "no" feedback information; maybe after 3 revisions, the suspicious probability of the base station is not lower than the suspicious probability threshold by 20%, but the server receives according to the The feedback information finds that the number of feedback information with feedback "yes" is less and less, and the number of feedback "no" feedback information is increasing. Therefore, it is highly probable that the base station is not a pseudo base station, and the server can 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 the multiple terminals. Therefore, the accuracy of the obtained information of the real base station and the information of the pseudo base station is relatively high. That is, the server receives the information of the event sent by the multiple terminals, and the information of the event may include the terminal identifier, the location information of the terminal, the information of the base station accessed when the event occurs, and the time when the event occurs. The server acquires information of the real base station and information of the pseudo base station according to the information of the event sent by the multiple terminals. The server may further determine, according to the determined 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, and send the indication information of the pseudo base station to the target terminal, so that the user occurs on the target terminal. The incident caused vigilance and was carefully deceived.

Further, the server may also use the characteristics of the pseudo base station to combine with the feedback information of the terminal, 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 event reported by the first terminal next time. And determining, according to the updated information of the real base station and the information of the pseudo base station, whether the first base station accessed by the terminal when the first event occurs is a pseudo base station, such that the real base station information and the pseudo base station are updated according to the real time. The accuracy of the results judged by the information is higher.

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

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

In the embodiment of the present application, the server receives information about a first event sent by the first terminal. It should be noted that the first terminal may be a terminal in the foregoing multiple terminals, or may be another terminal newly accessed outside the multiple terminals. Moreover, the number of representations of the first terminal is not limited, and may refer to one terminal or multiple terminals. In the following description, the first terminal is referred to as the mobile phone 1 as an example. 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 identifier of the mobile phone 1, the location information of the mobile phone 1, and the information of the first base station that is accessed when the first event occurs.

Information 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 may have several different implementation manners, which are respectively described below:

The first way: the server performs a lookup determination in the information of the real base station and the information of the pseudo base station stored in the database.

If the step 712 is after the step 702 and before the step 709, the server may perform the search in the information of the real base station and the information of the pseudo base station acquired according to the information of the event sent by the multiple terminals, if the information of the first base station is in the information of the pseudo base station. The first base station is a pseudo base station, and the server may 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 information of the real base station, the first base station is a real base station, and the server may not 1 Send the indication information of the real base station.

If the step 712 is after the step 709 and before the step 713, the server may perform the search in the information of the updated real base station and the information of the pseudo base station, and if the information of the first base station is in the information of the updated pseudo base station, A base station is a pseudo base station, and the server may 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 information of the updated real base station, the first base station is a real base station, and the server may not send the message to the mobile phone 1. The indication information of the real base station.

The second way: if step 712 is after step 702 and before step 709, the server may first search for information of the first base station by using the information of the pseudo base station stored in the database and the information of the real pseudo base station. Alternatively, if step 712 is after step 709 and before step 713, the server may first search for information of the first base station in the updated real base station information and the updated pseudo base station information stored 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 the approaching to 1 can be regarded as a real base station, and the approaching to 0 can be regarded as a pseudo base station. 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 can 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 mode: 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 head 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 the embodiment of the present application, if it is determined that the first base station is a pseudo base station by using any one of the methods described in step 714 to determine the authenticity of the first base station, the server sends the pseudo base station to the first terminal. Instructions.

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

For the manner in which the first terminal prompts the indication information of the pseudo base station, reference may be made to the prompting manner of any of the foregoing FIG. 4(c) to FIG. 4(p), and details are not described herein again.

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 the multiple terminals. Therefore, the accuracy of the obtained information of the real base station and the information of the pseudo base station is relatively high. That is, the server receives the information of the event sent by the multiple terminals, and the information of the event may include the identifier of the terminal, the location information of the terminal, the information of the base station that is accessed when the event occurs, and the time when the event occurs. The server determines information of the real base station and information of the pseudo base station according to the information of the event sent by the multiple terminals. The server may further determine, according to the determined 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, and send the indication information of the pseudo base station to the target terminal, so that the user occurs on the target terminal. The first incident caused vigilance and was carefully deceived.

Further, the server may also select, according to the suspicious probability corresponding to the information of the real base station and the information of the pseudo base station, a batch of information of the base station 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, and perform model training. A reference weight of each feature included in the information of the base station is obtained. The reference weights may be used when the server receives the information of the first event reported by the first terminal, and according to the reference weight of each feature and the information of the first base station, calculate the first base station that is 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 the indication information of the pseudo base station to the terminal. In this way, the server can calculate whether the access is a pseudo base station when the first event newly received by the server is received according to the reference weight of each feature included in the information of the base station, and provide another method for determining the pseudo base station. Increase the feasibility of the program.

On the other hand, according to the information of the events reported by a large number of terminals and the feedback information of the user, the suspicious probability of the real base station and the pseudo base station can be continuously optimized and corrected, which greatly improves the accuracy of the judgment; The identification method can only be compared with the existing base station data of the operator, and has a high accuracy in the case of judging the mobile base station. 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 of the identification, and can be found in time for the new pseudo base station; and can also identify the pseudo base station according to the technology of big data. The motion trajectory can further prevent pseudo base station scams and even capture pseudo base stations.
