Description

Pseudo base station positioning method and device, and information reporting method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a pseudo base station positioning method and apparatus, and an information reporting method and apparatus.

Background

The pseudo base station is a high-tech instrument and generally comprises a host and a notebook computer. The pseudo base station is usually disguised as a base station of an operator, and searches for the information of the mobile phone card within a certain radius range by using a short message group sender, a short message sender and other related equipment. And by using the acquired mobile phone card information, the mobile phone number of other people is arbitrarily falsely used to forcibly send short messages such as fraud, advertising and the like to the mobile phone of the user acquiring the mobile phone card information.

The operation flow of the pseudo base station is shown in fig. 1.

The pseudo base station firstly suppresses Global System for Mobile communication (GSM) signals of surrounding cells by using high-power broadcast signals, so that surrounding Mobile phone users change the cells to which the Mobile phone users belong in succession and change the cells to the pseudo base station cells due to the difference of signal intensity. The pseudo base station also broadcasts a special location area identifier, so that the mobile phone finds that a new location area is entered and needs to be updated. In the position area updating stage, the pseudo base station is simulated into a real base station to interact with the mobile phone user. In the authentication process, an International Mobile Subscriber Identity (IMSI) of the mobile phone subscriber, that is, a unique identifier of the mobile phone subscriber in the whole network range is obtained. After the location area is updated, the pseudo base station uses the obtained IMSI to page the mobile phone user. After the mobile phone user responds, the pseudo base station sends a short message to the mobile phone user, wherein the calling number can adopt a forged number. Therefore, the pseudo base station can send a fraud short message to the mobile phone user responding by using the fake number to cheat the mobile phone user.

Criminal suspects usually place the equipment of the pseudo base station in a car, drive the car slowly or stop the car in a specific area, search for the mobile phone card information in the range, and carry out short message fraud or advertising promotion on mobile phone users who acquire the mobile phone card information. Because the pseudo base station equipment is hidden and has strong mobility, the difficulty of checking and treating by a supervision department is improved.

Another hazard of the pseudo base station is that the user cannot normally use the service provided by the operator, the mobile phone user generally returns to normal after temporarily disconnecting the network for 8-12 seconds, and part of the mobile phone users must be powered on and off to access the network again.

The prior art mainly solves the problem of the pseudo base station and has the following three schemes:

the first scheme is as follows: through the contact way given in the illegal advertising information, the related personnel are found and then examined, which does not belong to the technical problem.

Scheme II: the mobile phone of the user is helped to identify the fake information sent by the fake base station, and then the fake short message is shielded and deleted. The normal short message is with the called number (e.g. 1381234567), but the called number is not available to the pseudo base station. The pseudo base station is addressed by the IMSI and sends the short message, so that the fraud short message or the advertising promotion short message sent by the pseudo base station does not carry the called number. Therefore, when the user mobile phone receives the short message, whether the received short message has the called number is checked, if not, the short message is determined to be the short message sent by the pseudo base station, and the short message is shielded and deleted.

The third scheme is as follows: the pseudo base station is located by the following two methods.

The method comprises the steps that a radio supervision mechanism is used for searching by a wireless signal analysis method, and therefore the position of a pseudo base station is located;

and secondly, detecting the positions and the movement tracks of suspected pseudo base stations and criminals by utilizing an analysis operator signaling system and identifying the abnormal phenomenon of 'sudden increase of updating of a position area in a certain area'.

For the first scheme, related personnel are found according to the contact information in the advertisement information, and the pseudo base station can be found through the method, but the checking and processing efficiency is extremely low, and a large amount of police force and material resources are consumed.

For the second scheme, the problem that the user mobile phone is temporarily disconnected due to the interference of the pseudo base station high-power signal, and the service provided by the operator cannot be normally used, which can only help the user to shield the short message issued by the pseudo base station, is not completely solved.

Therefore, the problem of the pseudo base station can be fundamentally solved only by positioning to a specific position of the pseudo base station. As the third solution also focuses on how to find the pseudo base station, the starting point of the third solution is that the professional uses a special device to search. The searching effect of the third scheme is limited by the input personnel, and the positioning precision can only reach the level of a location area or the level of a cell through technical means such as signaling flow of an operator, and the third scheme still has certain difficulty in finding the specific position of the pseudo base station and checking illegal behaviors of the pseudo base station.

In summary, to solve the problem of the pseudo base station fundamentally, only the specific geographical position of the pseudo base station is located. Although the suspected fake base station can be detected quickly and the mobile phone of the suspected criminal can be locked through technical means such as operator signaling flow and the like, the searching effect is limited by the input personnel, and the method can only locate the cell level, find the specific position of the equipment of the fake base station and check illegal behaviors of the fake base station, and still has certain difficulty.

Detailed Description

The embodiment of the invention provides a pseudo base station positioning method and equipment, which are used for positioning a pseudo base station.

The embodiment of the invention provides a technical scheme for positioning the pseudo base station by using a technical means of uploading information by User Equipment (UE), which is favorable for matching the illegal activity of striking the pseudo base station.

The embodiment of the invention is based on the fact that the number of GSM user terminals is large, the position of the pseudo base station can be positioned by using the position acquisition function of a Global Positioning System (GPS) of a common mobile phone and taking the mobile phone as a detector to detect the existence of the pseudo base station through summarizing the reported information. Particularly, when the position of the mobile terminal is judged not to move through the GPS, if the identification of the serving cell, the identification of the position area, or the signal of the serving cell changes greatly, the signal of the pseudo base station can be regarded as appearing. When the existence of the pseudo base station is detected, the information such as the geographical position coordinates of the pseudo base station is collected and reported to a server, so that the specific geographical position of the pseudo base station is positioned.

The embodiment of the invention will be described from two aspects of a user terminal UE and a pseudo base station positioning server.

Firstly, a user equipment UE needs to report information for positioning a pseudo base station to a network side, and the specific processing flow includes:

the UE determines that a pseudo base station occurs;

acquiring information for positioning a pseudo base station;

and reporting the acquired information for positioning the pseudo base station to a pseudo base station positioning server.

Preferably, the determining, by the UE, that a pseudo base station occurs specifically includes:

and when the UE determines that the geographical position of the UE is unchanged and needs to update the location area due to entering a new location area, the UE determines that a pseudo base station appears.

The pseudo base station needs to update the location area of the UE to acquire the IMSI, and sends fraud short messages to the UE by using the acquired IMSI. Therefore, if the UE detects that its geographical location has not changed, but needs to perform location area update due to currently entering a new location area, it may be determined that the UE receives a location area update signal of the pseudo base station, and thus it is determined that the pseudo base station occurs.

The UE can determine that the geographical position of the UE is not changed by determining that the geographical position of the UE is not changed, namely the UE is static by determining that the geographical position of the UE is not changed when the position change amount of the UE is lower than 15 meters, wherein the position change amount is 0 or is lower than a certain very small numerical threshold within a precision range through a positioning module such as a GPS/Beidou navigation system configured by the UE;

or, when the UE recognizes that the self moving speed is zero or lower than a preset speed threshold value through the positioning device or the sensor, it determines that the self geographical location is unchanged. That is, other sensor modules (such as speed, acceleration, etc.) can also identify that the self-movement speed is 0 or below a certain small numerical threshold within the accuracy range. For example, the threshold may be set to a moving speed of less than 0.2 meters per second, and it may be determined that the UE itself is not in a changed geographical location, i.e., the UE itself is stationary.

The UE may also determine that a fake base station occurs when receiving a short message not carrying the called number. Because the pseudo base station can only obtain the IMSI of the UE and cannot obtain the specific number of the UE, the short message sent by the pseudo base station does not carry the called number. Therefore, if the short message center attaches the called number to the sent short message, the UE can check whether the short message of the pseudo base station is received by checking whether the short message contains the called number, and further can determine whether the pseudo base station appears.

When the UE receives the short message in the location area update process, it may also determine that a pseudo base station occurs, for example, the pseudo base station performs location area update by using the UE, and sends the short message to the UE before releasing Radio Resource Control (RRC) connection before and after a Non-access stratum (NAS) signaling process related to the location area update. In a normal flow, the short message is sent immediately, rather than before or after the location area update. It is possible to judge the occurrence of the pseudo base station by this phenomenon from the perspective of the UE.

Preferably, the information reported by the UE to the network side for positioning the pseudo base station includes: geographical location coordinates of the UE.

Optionally, the information reported by the UE to the network side for positioning the pseudo base station may further include one or a combination of the following information: the time of reporting the geographical position coordinates of the UE, the cell identification carried by the broadcast information in the access cell reported by the UE, the position area identification, the signal intensity of the access cell, the occurrence of the pseudo base station and other broadcast information.

Preferably, the UE reports the acquired information for positioning the pseudo base station to the pseudo base station positioning server through a cellular network mode other than a global system for mobile communications GSM mode, such as Code Division Multiple Access (CDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Long term Evolution (Long Time Evolution, LTE, etc.), or a WIFI network; for UE with only one mode in standby, when the UE identifies that the UE currently resides in a pseudo base station, the UE actively switches to other modes, and reports information for positioning the pseudo base station; for the UE only in the GSM mode, the information for positioning the pseudo base station can be reported in a delayed manner after the UE recovers to access the operator network.

The information reported in a delayed manner for positioning the pseudo base station may be a result of one measurement or a set of results of multiple measurements. Preferably, when the UE confirms that the UE resides in the pseudo base station, even if the UE moves from its geographical location, the UE geographical location coordinates, the time of its geographical location coordinates, and the strength of the signal received in the cell of the pseudo base station may be reported as a set of measurement results. The content reported by taking the group as a unit is more helpful for helping the pseudo base station positioning server to know the motion track and the motion rule of the pseudo base station.

Preferably, after the UE determines that the pseudo base station occurs, the UE periodically acquires and reports information currently used for positioning the pseudo base station.

Preferably, the function of the UE for detecting the occurrence of the pseudo base station may be continuously run in the background after the startup software is started, or may be started and terminated according to the request and trigger of the pseudo base station location server. Under the trigger of the pseudo base station positioning server, the function of detecting the occurrence of the pseudo base station by the UE is started and stopped, and the effect of saving electricity for the UE can be achieved.

Correspondingly, on the network side, the specific process of the server in locating the pseudo base station includes:

the method comprises the steps of obtaining information which is reported by at least one UE and used for positioning the pseudo base station, and positioning the pseudo base station according to the obtained information which is reported by at least one plurality of user equipment UE and used for positioning the pseudo base station.

When the information for positioning the pseudo base station reported by the UE includes the geographical location coordinate of the UE, preferably, the positioning the pseudo base station according to the information for positioning the pseudo base station reported by at least one user equipment UE includes:

and grouping the UE according to the acquired geographical position reported by each UE and the time of reporting the geographical position coordinate of each UE. Wherein, the same group of UE corresponds to the same pseudo base station;

The rule of grouping according to the geographical position coordinates is that the distance between each UE in the same group of UEs is within a preset distance range, and the difference of the time of reporting the geographical position coordinates by each UE in the same group of UEs is not more than a preset time length range. For example, since the coverage distance of the pseudo base station is usually 500 meters, the distance between each UE in the same group of UEs does not exceed 500 meters, and the difference between the time when each UE in the same group of UEs reports its own geographical location coordinate does not exceed 30 seconds.

When the information reported by the UE for positioning the pseudo base station further includes a cell identifier and a location area identifier carried by broadcast information in an access cell of the UE, preferably, the positioning the pseudo base station according to the information reported by at least one user equipment UE for positioning the pseudo base station includes:

The rule of grouping according to the cell identifier and the position area identifier carried by the broadcast information in the access cell is as follows: since the cell identifiers and the location area identifiers carried by the broadcast information of the same base station are fixed, if the cell identifiers carried by the broadcast information of the access cells and the location area identifiers are the same in the information reported by the UE for positioning the pseudo base station, the same pseudo base station corresponding to the UE reporting the information for positioning the pseudo base station is divided into the same group.

Preferably, the pseudo base station positioning server obtains information for pseudo base station positioning, and mainly includes:

passively receiving information which is actively reported by one or more pieces of UE and used for positioning a pseudo base station; or triggering the UE within the specified time and place range to report the information for positioning the pseudo base station, and then receiving the information for positioning the pseudo base station reported by the UE. Therefore, the number of input information sources for positioning the pseudo base station can be increased, the searching speed of the geographical position of the pseudo base station is increased, and the searching accuracy of the geographical position coordinate of the pseudo base station is accurate.

On one hand, the reason why the server receives the information for pseudo base station positioning reported by one or more UEs is hoped that UEs near the UEs (possibly under the coverage of the same pseudo base station) also report the information for pseudo base station positioning, so that the nearby UEs are triggered to report the information for pseudo base station positioning; in addition, other modes, such as reporting by the masses or analyzing by an operator that a location area signaling update abnormality occurs in some cells, may also be combined, so as to trigger the UE to report information for positioning the pseudo base station. In general, it is not limited to the former aspect.

Preferably, for each group of UEs, locating the same pseudo base station by using the information for locating the pseudo base station reported by the group of UEs includes: and calculating the geometric center point of the geographical position coordinates reported by the group of UE according to the geographical position coordinates reported by the same group of UE, wherein the geometric center point is the geographical position coordinates of the pseudo base station corresponding to the group of UE.

Or, when the information for positioning the pseudo base station reported by the UE further includes the received signal strength of the UE in the pseudo base station cell, preferably, in order to more accurately position the geographical position coordinate of the pseudo base station, the distance between the UE and the pseudo base station corresponding to the group of UEs is determined by using the received signal strength of each UE in the same group of UEs in the pseudo base station cell.

If the group consists of three UEs, the method for locating the same pseudo base station by using the information for locating the pseudo base station reported by the group of UEs for the group consisting of three UEs includes:

If the group consists of more than three UEs, for every three UEs in the group, the following steps are performed: determining a geographical position coordinate pre-estimated value of the pseudo base station corresponding to the group of UE calculated by the three UEs by using a three-point positioning algorithm according to the geographical position coordinate of each UE in the three UEs and the distance between the UE and the pseudo base station corresponding to the group of UE; and calculating the geometric center position coordinate of the geographical position coordinate pre-estimated value to serve as a final estimated value of the geographical position coordinate of the pseudo base station corresponding to the group of UE.

For example, there are four user equipments, A, B, C, D, under the same pseudo base station, and the information for positioning the pseudo base station is reported separately, and a first pre-estimation value of the pseudo base station geographical location coordinate corresponding to the group of UEs is obtained according to the geographical location coordinate of the user equipment A, B, C and the distance between the user equipment A, B, C and the pseudo base station; by analogy, according to the geographical position coordinates of the user equipment B, the user equipment C and the user equipment D and the distances between the user equipment B, the user equipment C and the user equipment D and the pseudo base stations corresponding to the group of UE, obtaining a second pre-estimation value of the geographical position coordinates of the pseudo base stations corresponding to the group of UE; obtaining a third pre-estimation value of the geographical position coordinates of the pseudo base stations corresponding to the group of UE according to the geographical position coordinates of the user equipment A, the user equipment C and the user equipment D and the distances between the user equipment A, the user equipment C, the user equipment D and the pseudo base stations corresponding to the group of UE; and obtaining a fourth pre-estimation value of the geographical position coordinates of the pseudo base stations corresponding to the group of UE according to the geographical position coordinates of the user equipment A, the user equipment B and the user equipment D and the distances between the user equipment A, the user equipment B, the user equipment D and the pseudo base stations corresponding to the group of UE. And then calculating the average value of the first, second, third and fourth pre-estimated values, namely the geometric center position coordinates of the four geographic position coordinates, wherein the geometric center position coordinates are the final position estimated values of the pseudo base station.

The specific calculation method of the three-point positioning principle comprises the following steps: since the unknown point is necessarily located on a sphere centered at the known point and spaced from the known point by a radius, if the distances of the unknown point and the three known points can be measured, the unknown point is at the intersection of the three sphere circumferences.

The following takes two scenarios as an example to further explain the technical solution provided by the embodiment of the present invention.

The method comprises the steps of positioning the pseudo base station under the premise that the geographical position of the UE is unchanged, but the UE enters a new position area and needs to be updated.

After the pseudo base station appears, the signals of normal base stations in a certain nearby area are covered by high-power broadcast signals, and UE in the coverage range of the pseudo base station is attracted to be prompted to carry out location area updating.

The pseudo base station detection function of the handset terminal A, B, C near the pseudo base station is in an on state. A. B, C, according to the judgment of its own GPS module, it is known that A, B, C is all in a static state, but because of receiving a high-power signal from the pseudo base station, it is found that the location area of the cell where it resides is changed, and it is necessary to update the location area.

Since the phenomenon conforms to the characteristics of the pseudo base station, A, B, C reports the occurrence of the pseudo base station, the current geographical position coordinates and the received signal strength in the pseudo base station cell to the pseudo base station positioning server.

And the pseudo base station positioning server comprehensively arranges the reported information and calculates the geographic position coordinates of the pseudo base station based on the three-point positioning principle.

And a second scenario is a positioning process of the pseudo base station on the premise of receiving the short message only identified by the IMSI.

After the pseudo base station appears, covering the signal of a normal base station in a certain nearby area by using a high-power broadcast signal, prompting the UE in the coverage range of the pseudo base station to update the location area by attraction, collecting the IMSI of the UE in the coverage range of the pseudo base station, and then sending a short message to the UE by taking the IMSI as an identifier.

The cell phone terminal A, B, C, D, E, F has pseudo base station detection function, but only A, B, C, D is near the pseudo base station, and only the pseudo base station detection function of a is in on state.

And B, determining that the A receives the signal of the pseudo base station as the short message only taking the IMSI as the identifier conforms to the appearance characteristic of the pseudo base station, and reporting the occurrence event of the pseudo base station, the current geographical position coordinate of the pseudo base station and the TA identifier under the cell of the pseudo base station to a positioning server of the pseudo base station.

After the pseudo base station positioning server obtains the event reported by a, more information for positioning the pseudo base station needs to be collected.
