The invention provides a method for identifying a 4G pseudo base station.

The identification method of the 4G pseudo base station comprises the following steps:

receiving a cell update event of an LTE system and acquiring a system message;

Before this embodiment, a basic principle of this solution is explained, in the present invention, a standard cell identification information base (also called a core network database) is established in a server (also called a cloud server, a server at a carrier level), during a cell update process, a terminal reads a system message first, when the system message is read, the terminal acquires and generates cell identification information from the system message, and simultaneously transmits frequency point information in the system message to the server, so that the server queries standard cell identification information in a core network database (in the core network database, standard cell identification information generated according to eNodeB ID and CID is stored), the server transmits the standard cell identification information to a terminal local UE database, the terminal compares the generated cell identification information with the standard cell identification information in the UE database, and if the generated cell identification information is different from the standard cell identification information in the UE database, determining that the cell where the terminal resides is a pseudo base station cell.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for identifying a 4G pseudo base station according to a first embodiment of the present invention.

In this embodiment, the method for identifying a 4G pseudo base station may be optionally applied to a terminal, where the terminal may be selected as the mobile terminal illustrated in fig. 1, and the method for identifying a 4G pseudo base station includes:

and step S11, receiving a cell update event of the LTE system and acquiring a system message.

The cell update event of the terminal LTE system refers to cell selection, cell reselection, cell handover, and the like of the terminal, where the terminal automatically triggers a cell update event of the LTE system and acquires a system message sent by the base station when the cell selection (cell selection refers to selecting a most suitable cell according to the C1 algorithm when the mobile phone is turned on), cell reselection (the mobile phone changes from one cell or channel to another cell or channel (mainly according to the C2 algorithm) in Idle mode), or cell handover (cell handover refers to changing from one cell or channel to another cell or channel in Active mode, where the cell handover includes switching between internal channels or timeslots of the same cell).

The system information comprises measurement information and frequency point information, wherein the measurement information comprises a base station name eNodeB ID and a base station positioning parameter (CI or CID), namely the system information comprises multi-group data; each group of data comprises a frequency point information, a base station name and a tracking area code corresponding to a corresponding base station positioning parameter and a frequency point; the system information includes information of a plurality of cells, wherein the frequency points correspond to the cells one to one, for example, the system information includes a plurality of groups of data corresponding to the cells, a first cell, the frequency point corresponding to the first cell, a first base station name corresponding to the first cell, and a first base station positioning parameter corresponding to the first base station; a second cell, a frequency point corresponding to the second cell, a second base station name corresponding to the second cell, a second base station positioning parameter corresponding to the second base station, and the like

Meanwhile, the terminal sends the system information to the server, so that the server queries standard cell identification information in a core network database (the core network database stores standard cell identification information generated according to eNodeB ID and CID) through frequency point information in the system information, the server sends the standard cell identification information to a terminal local UE database and updates the standard cell identification information to a local preset UE database, and the fact synchronization of the current information can be ensured after cell selection/cell reselection/cell switching occurs in a cell.

And step S12, processing the measurement information in the system information according to a preset rule to generate cell identification information.

The terminal processes the base station name and the base station location parameter in the system information according to a preset rule (preset rule processing: setting according to specific situations, and not limiting specifically in this embodiment), for example, the terminal processes the base station name and the CID base station location parameter (also called CID) in the system information according to a preset rule to generate and obtain cell identification information.

It should be added that: in this embodiment, the cell identification information generated by the terminal and the standard cell identification information generated by the server may be the same or different, that is, when the cell in which the terminal resides is a cell of each operator base station, eNodeB ID (base station name) and base station positioning parameters included in the system information of the terminal are the same as eNodeB ID and base station positioning parameters included in the server, and meanwhile, the same preset rule is used by the terminal and the server, so that the cell identification information obtained in the terminal is the same as the standard cell identification information in the server; when the cell where the terminal resides is a cell of a pseudo base station, the eNodeB ID (or the pseudo eNodeB ID) and the base station positioning parameter that may not be included in the terminal system information are different from the eNodeB ID and the base station positioning parameter that are included in the server, so that the cell identification information obtained in the terminal is different from the standard cell identification information in the server even though the preset rule used by the server in the terminal is different from the standard cell identification information in the server.

Step S13, the cell identification information is traversed and matched with a preset UE database to judge whether the corresponding resident cell in the cell update event of the LTE system is a pseudo base station cell.

The method comprises the steps that a terminal conducts traversal matching on cell identification information and a preset UE database, wherein standard cell identification information is stored in the preset UE database, namely the terminal receives a cell updating event of the LTE system, the terminal conducts traversal matching on the cell identification information and the standard cell identification information in the preset UE database so as to judge whether the standard cell identification information matched with the cell identification information exists in the preset UE database, and if the standard cell identification information matched with the cell identification information exists in the preset UE database, a resident cell corresponding to the cell updating event in the LTE system is not a pseudo base station cell; specifically, step S13 further includes:

step a, traversing and matching the cell identification information with standard cell identification information in a preset UE database to judge whether the standard cell identification information matched with the cell identification information exists in the preset UE database;

and b, if the standard cell identification information matched with the cell identification information exists in a preset UE database, judging that a resident cell corresponding to the cell updating event of the LTE system is not a pseudo base station cell.

Step S14, if the cell is not a pseudo base station cell, triggering a location update event.

When the terminal determines that the cell is not a pseudo base station cell, it sends out a Location update event (Location update: a roaming mobile user can move freely in the GSM network, and the network keeps track of the mobile user's Location, so that the mobile user can receive calls wherever he is, in order to keep track of the mobile user's current Location, the MS (mobile station) must inform the system when it changes its Location area (Location area), which is a defined area handled by one or several BTSs, in which the MS can move freely without informing the system, and is controlled by one or several BSCs, but only belongs to one msc, which is called Location update), i.e. when the terminal determines that the corresponding base station information is not a pseudo base station, the terminal Location update is carried out.

In this embodiment, the terminal processes the measurement information in the system message according to a preset rule to generate cell identification information, and the terminal compares the cell identification information with standard cell identification information in a preset UE database to determine whether a resident cell corresponding to a cell update event of the LTE system is a pseudo base station cell; if the resident cell is not a pseudo base station cell, triggering a position updating event; if the resident cell is a pseudo base station cell, the corresponding information is generated into a forbidden access list, so that the problem that the pseudo base station is illegal is solved fundamentally, the current situation that all users receive spam short messages can be changed, and the comprehensiveness, accuracy and efficiency of pseudo base station identification are improved.

Further, referring to fig. 4, this embodiment is provided on the basis of the first embodiment, and a difference between this embodiment and the first embodiment is that, in this embodiment, it is specifically described that, when the cell identification information is different from the standard cell identification information, the step of further determining whether the camping cell corresponding to the cell update event of the LTE system is a pseudo base station cell is further performed:

in a second embodiment of a method for identifying a 4G pseudo base station, the method for identifying a 4G pseudo base station includes:

step S21, if there is no standard cell identification information matching with the cell identification information in the preset UE database, obtaining the frequency point information in the system information.

If standard cell identification information matched with the cell identification information does not exist in a preset UE database, acquiring frequency point information in the system information, wherein the frequency point information refers to a number of fixed frequency; in the GSM network, frequency points are used to replace frequencies to specify the transmitting frequency of the transceiver group.

Step S22, determine whether the tracking area codes corresponding to the frequency points in the frequency point information are all the same.

The terminal judges whether the Tracking area codes corresponding to each frequency point in the frequency point information are all the same (the Tracking area codes are called TACs, and parameters are English names: Tracking area codes of cell served by neighbor Enb, Tracking area codes to which TAC value cells belong, and one Tracking area can cover one or more cells).

Step S23, if the tracking area codes corresponding to the frequency points in the frequency point information are not all the same, the corresponding residential cell in the cell update event of the LTE system is a pseudo base station cell.

According to the method, tracking area codes of frequency points corresponding to a central cell and adjacent cells of a base station are the same, if the tracking area codes of the corresponding frequency points in the central cell and the adjacent cells are not all the same, a resident cell corresponding to a cell updating event of an LTE system is a pseudo base station cell, if the tracking area codes of the corresponding frequency points in the central cell and the adjacent cells are all the same, a terminal can determine that standard cell identification information in a server core database is not updated timely, and the resident cell corresponding to the cell updating event of the LTE system is not a pseudo base station cell.

In this embodiment, when the cell identification information is different from the standard cell identification information, considering a situation that a standard cell in a server is updated timely, it is not directly determined that a resident cell corresponding to a cell update event of the LTE system is a pseudo base station cell, but a re-determination is performed according to tracking area codes of corresponding frequency points of a central cell and a neighboring cell, if tracking area codes corresponding to the frequency points in the frequency point information are not all the same, a resident cell corresponding to the cell update event of the LTE system is a pseudo base station cell, and if a tracking area code is included in a preset range, a resident cell corresponding to the cell update event of the LTE system is not a pseudo base station cell, so that identification of the pseudo base station information is more accurate.

Further, referring to fig. 5, the present embodiment is proposed on the basis of the second embodiment, and the difference between the present embodiment and the second embodiment is that, in the present embodiment, the operation steps of generating the prohibited access list at the terminal after determining that the base station information is the pseudo base station information are specifically described:

in a third embodiment of a method for identifying a 4G pseudo base station, the method for identifying a 4G pseudo base station includes:

step S31, acquiring cell identification information corresponding to the frequency point with abnormal tracking area code, and using the cell identification information as pseudo base station information;

and step S32, adding the pseudo base station information to a preset UE database to generate a forbidden access list.

After the terminal determines that the resident cell is a pseudo base station cell, the terminal determines cell identification information corresponding to a frequency point with an abnormal tracking area code, for example, if the tracking area code corresponding to 1 frequency point is different from the tracking area codes corresponding to the other 4 frequency points, the terminal takes 1 frequency point as the abnormal frequency point, the cell identification information corresponding to the frequency point as the pseudo base station information, and the cell identification information is taken as the pseudo base station information, the terminal adds the pseudo base station information to a preset UE database, and prohibits accessing a list, so as to directly determine whether the resident cell is the pseudo base station cell according to the prohibited access list.

In this embodiment, after determining that a resident cell corresponding to a frequency point with an abnormal tracking area code in a cell update event of the LTE system is a pseudo base station cell if tracking area codes corresponding to the frequency points in the frequency point information are not all the same, a terminal acquires cell identification information corresponding to the frequency point with the abnormal tracking area code, and uses the cell identification information as pseudo base station information; the pseudo base station information is added to a preset UE database to generate an access prohibition list, and the terminal can accurately determine whether the resident cell is a pseudo base station cell through the access prohibition list.

Further, referring to fig. 6, this embodiment is proposed on the basis of the first embodiment and the third embodiment, and the difference between this embodiment and the third embodiment is that the step of determining whether the camping cell is a pseudo base station cell according to the forbidden access list is specifically described in this embodiment:

in a fourth embodiment of a method for identifying a 4G pseudo base station, the method for identifying a 4G pseudo base station includes:

traversing and matching the cell identification information with standard cell identification information in a preset UE database to judge whether the standard cell identification information matched with the cell identification information exists in the preset UE database, and executing the following steps:

step S41, traversing and matching the cell identification information with a forbidden access list in a preset UE database to judge whether the matched cell identification information exists in the forbidden access list;

step S42, if there is matching cell identification information in the forbidden access list, the corresponding resident cell in the cell update event of the LTE system is a pseudo base station cell.

Step S43, if there is no matching cell identification information in the forbidden access list, performing traversal matching between the cell identification information and standard cell identification information in a preset UE database to determine whether there is standard cell identification information matching with the cell identification information in the preset UE database.

The terminal conducts traversal matching on the cell identification information and a forbidden access list in a preset UE database to judge whether the forbidden access list has matched cell identification information or not, and if the forbidden access list has the matched cell identification information, a resident cell corresponding to a cell updating event of the LTE system is a pseudo base station cell; and if the matched cell identification information does not exist in the forbidden access list, executing a step of traversing and matching the cell identification information with standard cell identification information in a preset UE database.

In this embodiment, when determining that the camping cell is the pseudo base station cell, the forbidden access list is correspondingly generated, and when the terminal pseudo base station is identified next time, the cell identification information and the forbidden access list may be used first, and when the forbidden access list includes the cell identification information, it is determined that the camping cell is the pseudo base station cell, which accelerates the identification efficiency of the 4G pseudo base station.

Further, in a fifth embodiment of the method for identifying a 4G pseudo base station according to the present invention, the method for identifying a 4G pseudo base station is applied to a server, and the method for identifying a 4G pseudo base station includes:

referring to fig. 7, the step of the server establishing the standard cell identification information includes:

step S51, when receiving the request for establishing the standard cell identification information, obtaining the name of the base station and the positioning parameters of the base station preset in the server.

When the server receives a request for establishing standard cell identification information, the name of a base station and base station positioning parameters preset in the server are obtained, namely, the server is a cloud server and divides a mobile network into three parts, namely, a base station subsystem, a network subsystem and a system supporting part, such as safety management and the like. The cloud server can be a base station subsystem, a network subsystem and a hardware carrier supported by the system, and the server obtains a base station name and a base station positioning parameter.

And step S52, processing the base station name and the base station positioning parameter according to a preset rule to obtain standard cell identification information.

The server processes the base station name and the base station positioning parameter according to a preset rule (the preset rule is set according to a specific situation, and what needs to be supplemented is that the preset rule in the terminal is the same as the preset rule in the server) to obtain standard cell identification information, for example, a core network database of the server is used for storing all E-NodeB IDs (Evolved Node B, base station names in LTE) and CIDs (also called base station positioning parameters) in the current network, and generating and obtaining unique ECI (standard cell identification information).

Step S53, establishing association relation between the standard cell identification information and the corresponding frequency point information, so as to inquire the standard cell identification information according to the frequency point information.

The terminal establishes the association relationship between the standard cell identification information and the corresponding frequency point information, namely, the server maps the standard cell identification information and the frequency points one by one to inquire the standard cell identification information according to the frequency point information,

referring to fig. 8, the step of querying standard cell identification information according to frequency point information in the server includes:

step S61, receiving a query request of standard cell identification information sent by a terminal, and acquiring frequency point information included in the query request.

The server receives a query request of standard cell identification information sent by the terminal, and acquires frequency point information included in the query request by referring to fig. 9, fig. 10, and fig. 11, where it needs to be supplemented to indicate that the frequency point information in the query request includes not only frequency point information of a central cell but also frequency point information of a neighboring cell.

Step S62, based on the frequency point information and the incidence relation, inquiring the standard cell identification information, and sending the standard cell identification information to the terminal.

The server inquires the standard cell identification information based on the frequency point information and the incidence relation, namely, the server sends the standard cell identification information to the terminal, so that the terminal compares the cell identification information generated by using the system information with the cell identification information in the server and judges whether the resident cell is a pseudo base station cell or not.

In the embodiment, the server enables the E-NodeB ID and the CID to be called base station positioning parameters again to generate standard cell information, so that the terminal can identify the pseudo base station cell through the standard cell information, and the pseudo base station can not be disguised again through the deployment of the cloud server operator level, namely, the pseudo base station cannot be registered in the cloud server of the operator, and only the normal base station of the mobile operator can be registered.

In addition, referring to fig. 12, an embodiment of the present invention further provides an identification system for a 4G pseudo base station, where the identification system for a 4G pseudo base station includes a terminal and a server that are connected in communication, where,
