Description

Method, equipment and system for pseudo base station identification and pseudo base station information sharing

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a device, and a system for pseudo base station identification and pseudo base station information sharing.

Background

At present, the phenomena of harassment of junk short messages and fraudulent telecommunication users sent by a pseudo base station are rampant, and bad consequences are caused to the property of the users, the information security and the like. To suppress this phenomenon, two schemes for identifying the pseudo base station are proposed in the prior art:

scheme 1: the method comprises the steps that a terminal collects the characteristics of a pseudo base station, when the terminal selects a cell residing in a Global System for Mobile Communications (GSM) network, the terminal checks whether the characteristics of the cell conform to the collected characteristics of the pseudo base station, if so, the terminal does not reside in the cell, and other cells capable of residing are continuously searched. However, this solution is a passive defense solution, because the characteristics of the pseudo base station are not constant, when a new type of pseudo base station appears, the existing characteristics of the pseudo base station of the terminal need to be upgraded therewith to successfully identify the pseudo base station, which may result in the failure of pseudo base station identification.

Scheme 2: the terminal extracts keywords aiming at the content of the received short message, judges whether the short message is junk information or not according to the keywords, if so, the terminal determines that the base station which is resided at present is a pseudo base station, and otherwise, the terminal determines that the base station is a normal base station. However, the terminal in the above scheme merely determines that the currently camped base station is the pseudo base station by simply receiving the spam information, which may cause erroneous determination. In addition, it is assumed that the terminal determines correctly, but the terminal already camps on the pseudo base station, and therefore, the situation of accessing the pseudo base station cannot be effectively avoided.

Disclosure of Invention

By the method, the terminal can accurately judge the pseudo base station accessed by the terminal, and the accuracy of pseudo base station identification is improved.

In a possible implementation manner, after the terminal determines that the base station is a pseudo base station and initiates cell reselection, the method further includes: and the terminal acquires pseudo base station indication information and reports the pseudo base station indication information to a cloud server. The pseudo base station indication information comprises an identification parameter of the current resident cell, and the identification parameter comprises at least one of a cell frequency point number or a cell identification. Therefore, the terminal reports the identification result of the terminal to the cloud server by reporting the pseudo base station indication information, so that the cloud server provides the first pseudo base station identification information for other terminals.

Therefore, the cloud server can inform each terminal of the pseudo base station identification features, so that the pseudo base station identification features stored in the terminals can be updated in time, and the terminals are effectively prevented from being resident in the pseudo base stations.

The first pseudo base station identification information and the second pseudo base station identification information may be notified to the terminal twice, or may be notified to the terminal once.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The pseudo base station device is generally composed of a transceiver and a notebook computer. The pseudo base station mainly simulates a base station subsystem in a GSM network.

The Terminal referred to in the embodiments of the present invention may also be referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), and the like. The terminal is capable of communicating with one or more core networks via a Radio Access Network (RAN), and may be, for example, a mobile telephone (or "cellular" telephone).

The logical hierarchy of the terminal is shown in fig. 1, and includes an application layer (App), a Non-Access Stratum (NAS), and an Access Stratum (AS).

Specifically, a protocol stack of a Universal Mobile Telecommunications System (UMTS) is divided into a NAS protocol and an AS protocol. The NAS protocol handles the transmission of information between the terminal and the core network, and the content of the transmission may be user information or control information, such as establishment and release of services or mobility management information. The NAS message is to some extent independent of the AS protocol structure, independent of what radio access network is accessed. The Radio Access network may be a Global system for mobile communication (GSM), General Packet Radio Service (GPRS), Wideband Code Division Multiple Access (WCDMA), or the like. The AS protocol mainly processes flows such AS cell selection, radio resource management and the like.

The embodiment of the invention mainly aims at the GSM pseudo base station, so only the GSM access layer is involved.

Fig. 2 is a schematic view of a scenario in which a plurality of terminals report pseudo base station indication information to a cloud server and the cloud server pushes pseudo base station identification information to the plurality of terminals according to the embodiment of the present invention. Fig. 2 includes a terminal 210, an access network 220, a server 230 in a core network, and a cloud server 240. The access Network 220 may be a Mobile communication Network (Mobile communication Network) or a Wireless Local Area Network (WLAN). The access network 220, the server 230 in the core network, and the Cloud server 240 exchange information through a Cloud service (Cloud service).

The spam message in the embodiment of the invention refers to a message which is not agreed by the user and is not willing to be received by the user, or a message which cannot be refused to be received by the user according to the intention of the user, such as a commercial advertisement message or a fraud message.

Referring to fig. 3, an embodiment of the present invention provides a pseudo base station identification method, including:

step 300: and the terminal receives the short message sent by the base station corresponding to the cell in which the terminal currently resides.

Step 310: the terminal judges whether the short message is a spam message.

Step 320: and the terminal initiates location area update to the base station under the condition of judging the short message to be a spam short message.

Step 330: and if the terminal judges that the updating of the position area fails, the terminal determines that the base station is a pseudo base station and initiates cell reselection.

Specifically, as shown in fig. 1, after receiving a short message sent by a base station corresponding to a current resident cell, a terminal identifies that the received short message is a spam short message through the existing spam identification technology, and then notifies the access stratum of the terminal in real time. Further, after sending the spam short message, the general pseudo base station kicks out the terminal residing therein, so that after sending the spam short message to the terminal, the pseudo base station changes its location Area, so that the non-access stratum of the terminal initiates Location Area Update (LAU), and the terminal leaves the pseudo base station to perform cell reselection if the location Area Update initiated by the terminal fails. For example, after receiving a location area update request sent by the terminal, the pseudo base station sends a location area update REJECT message (LAU REJECT) to the terminal, and if the terminal determines that the location area update fails, the pseudo base station notifies the access stratum of the terminal in real time. Optionally, the access stratum may further notify the access stratum of the terminal when the cause value carried in the location area update reject message is determined to be the preset cause value according to the cause value carried in the location area update reject message.

Therefore, when the access layer of the terminal receives the two notifications on the current resident cell, the base station corresponding to the current resident cell is judged to be a pseudo base station, and cell reselection is initiated to access a normal base station.

In addition, the terminal can also notify the application layer of the terminal of the message that the base station corresponding to the current resident cell is the pseudo base station, and notify the user.

It should be understood that the functions of the application layer of the terminal herein may be implemented by a pseudo base station identity Application (APP), and the functions of the access layer of the terminal herein and the non-access layer of the terminal herein may be implemented by a Modem (Modem). The pseudo base station identification application can obtain a pseudo base station identification result by calling a program in the Modem.

After step 330, the terminal obtains pseudo base station indication information, where the pseudo base station indication information includes an identification parameter of a current resident cell, and reports the pseudo base station indication information to the cloud server.

The terminal reporting the pseudo base station indication information may include, but is not limited to, the following two ways:

firstly, when a terminal is accessed to a network such as WiFi, pseudo base station indication information is directly reported to a cloud server;

and secondly, after the terminal successfully resides in the cell of the normal base station through cell reselection, reporting the indication information of the pseudo base station to a cloud server.

Wherein the identification parameter includes at least one of a cell frequency point number or a cell identification (cell ID). In addition, the identification parameter may further include a Network Color Code (NCC), a Base Transceiver Station color Code (BCC), a Mobile Country Code (MCC), a Mobile Network number (MNC) Location Area Code (LAC), and the like.

Specifically, the access layer of the terminal extracts the identifier parameter of the current resident cell and reports the identifier parameter to the application layer of the terminal.

Optionally, the pseudo base station indication information further includes a characteristic parameter of the current camped cell, where the characteristic parameter is used to describe a bearer capability of the current camped cell, and includes at least one of a cell selection parameter, a cell reselection parameter, a Common Control Channel (CCCH) parameter, a Random Access Channel (RACH) parameter, or an indication of whether GPRS is supported.

Specifically, the access layer of the terminal extracts the characteristic parameters of the current resident cell and reports the characteristic parameters to the application layer of the terminal.

Optionally, the pseudo base station indication information further includes location information of a current location of the terminal. It should be noted that, when reporting the location information of the current location of the terminal to the cloud server, the location information does not include any privacy information of the terminal user.

It should be understood that the identification parameter, the characteristic parameter and the location information may be reported separately, or the identification parameter may be reported to the cloud server together with the other two or one of the two.

Referring to fig. 4, an embodiment of the present invention provides a pseudo base station information sharing method, where for a cloud server side, the method includes:

step 400: the method comprises the steps that a cloud server receives pseudo base station indication information respectively reported by at least one first terminal, wherein the pseudo base station indication information comprises identification parameters of cells of pseudo base stations, and the identification parameters comprise at least one of cell frequency point numbers or cell identifications;

step 410: and the cloud server takes at least one identification parameter in the identification parameters as the identification information of the first pseudo base station.

Step 420: the cloud server pushes the first pseudo base station identification information to at least one terminal, so that the at least one terminal can identify whether the base station corresponding to the cell to be resided is a pseudo base station or not according to the first pseudo base station identification information.

For step 410, when the cloud server uses at least one of the identification parameters as the first pseudo base station identification information, the following methods may be adopted, but are not limited to: the cloud server counts the reporting times corresponding to different identification parameters in a preset time length, and takes at least n identification parameters in the front of the reporting times as identification information of the first pseudo base station, wherein n is more than or equal to 1.

For example, the cloud server receives the following five identification parameters, namely cell ID1, cell ID 2, cell ID 3, cell ID 4, and cell ID5, included in the pseudo base station indication information reported by each terminal in one hour, and counts the reporting times corresponding to the five identification parameters respectively by the cloud server, for example, if the identification parameters reported by the terminal a and the terminal B are both cell ID1, the reporting times of the cell ID1 is 2, and it is assumed that at least more reports are obtained by sorting the cell ID 4, the cell ID 2, the cell ID 3, the cell ID1, and the cell ID 5. At this time, the cloud server may notify the first two identification parameters with the largest number of times of reporting as the first pseudo base station identification information to each terminal, that is, the cell ID 4 and the cell ID 2 are used as the first pseudo base station identification information.

Optionally, the pseudo base station indication information further includes position information of a current position of the first terminal, and when the cloud server uses at least one of the identification parameters as the first pseudo base station identification information, according to the position information, statistics is performed on reporting times of different identification parameters in a plurality of preset geographical areas respectively, and the first pseudo base station identification information is pushed to terminals in the corresponding preset geographical areas.

For example, the cloud server receives that identification parameters included in pseudo base station indication information reported by each terminal within one hour are five, which are respectively cell ID1, cell ID 2, cell ID 3, cell ID 4 and cell ID5, the pseudo base station indication information further includes location information corresponding to the terminals, the cloud server determines that the cell ID1, the cell ID 2 and the cell ID5 belong to an area a and the cell ID 3 and the cell ID 4 belong to an area B according to the location information. The area a and the area B are preset areas defined in advance. Taking the area a as an example, it is assumed that the final reporting times are sorted by at least more times into cell ID 2, cell ID1, and cell ID 5. At this time, the cloud server may notify the terminal in the area a of the first two identification parameters with the largest number of times of reporting as the first pseudo base station identification information, that is, the cell ID 2 and the cell ID1 are used as the first pseudo base station identification information.

Therefore, the cloud server can perform early warning on the pseudo base station to the terminal in the corresponding area in a regional mode, the mode is more flexible and has pertinence, the terminal can be effectively prevented from residing in the pseudo base station, and the cost of the identification information of the first pseudo base station is saved.

Optionally, the pseudo base station indication information further includes a characteristic parameter of a cell of the pseudo base station, where the characteristic parameter is used to describe a bearer capability of the cell, and the characteristic parameter includes at least one of a cell selection parameter, a cell reselection parameter, a CCCH parameter, a RACH parameter, or an indication whether GPRS is supported. At this moment, the cloud server further extracts at least one characteristic parameter group as second pseudo base station identification information according to the characteristic parameters, each characteristic parameter group comprises at least one characteristic parameter, and the cloud server pushes the second pseudo base station identification information to at least one terminal, so that the at least one terminal can respectively identify whether a base station corresponding to the cell to be resided is a pseudo base station according to the second pseudo base station.

For example, the cloud server may be used as source data of big data mining according to feature parameters included in pseudo base station indication information respectively reported by at least one terminal, periodically analyze the latest technology of the pseudo base station, develop a new pseudo base station defense technology, and extract pseudo base station identification features. For example, when the cloud server analyzes the parameter value of the characteristic parameter a in a certain range according to the characteristic parameters of a large number of pseudo base stations, the base station corresponding to the cell where the terminal currently resides is a pseudo base station, and the cloud server can use the parameter value range of the characteristic parameter a as the second pseudo base station identification information.

Therefore, the cloud server can extract the latest pseudo base station identification features to notify the latest pseudo base station identification features to each terminal through the collected feature parameters, so that the pseudo base station identification features stored in the terminal can be updated in time, and the terminal is effectively prevented from being resident in the pseudo base station.

It should be understood that, in the present invention, the first pseudo base station identification information and the second pseudo base station identification information may be notified to the terminal twice, or may be notified to the terminal once, and the present invention is not limited thereto.

In addition, before the cloud server performs step 420, optionally, the cloud server receives a pseudo base station identification information sharing request respectively sent by at least one terminal, and replies the first pseudo base station identification information to the terminal sending the sharing request.

Referring to fig. 5, an embodiment of the present invention provides a pseudo base station information sharing method, where, for a terminal side, the method includes:

step 500: the method comprises the steps that a terminal receives first pseudo base station identification information pushed by a cloud server, wherein the first pseudo base station identification information comprises at least one identification parameter;

step 510: when the terminal selects to access the cell to be resided, judging whether a first identification parameter of the cell to be resided is the same as any identification parameter in the first pseudo base station identification information, wherein the identification parameter comprises at least one of a cell frequency point number or a cell identification;

step 520: under the condition that the first identification parameter is judged to be the same as any identification parameter in the first pseudo base station identification information, the terminal determines that a base station corresponding to the cell to be resided is a pseudo base station; the terminal does not access the cell to be camped on and continues to search for other cells.

Optionally, because the existing pseudo base station is generally a base station of a GSM network, when the terminal selects the cell to be camped as a cell corresponding to the base station of the GSM network, it is only necessary to determine whether the base station corresponding to the cell to be camped is a pseudo base station according to the first pseudo base station identification information.

Before the terminal performs step 500, the terminal may send a pseudo base station identification information sharing request to the cloud server, so that the cloud server sends the first pseudo base station identification information to the terminal in response to the sharing request.

Optionally, the terminal receives second pseudo base station identification information pushed by the cloud server, where the second pseudo base station identification information includes at least one feature parameter group, and each feature parameter group includes at least one feature parameter; the characteristic parameters include: at least one of cell selection parameters, cell reselection parameters, CCCH parameters, RACH parameters, or an indication of whether GPRS is supported;
