Description

A method and system for preventing a terminal from initiating a location update process under a pseudo base station

technical field

The invention belongs to the technical field of mobile communication, and in particular relates to a method and system for preventing a terminal from initiating a location update process under a pseudo base station.

Background technique

At present, in mobile communication systems, pseudo base stations are often used to attract mobile terminals to stay, thereby obtaining user private information or pushing information to users. A common working method of the pseudo base station is as follows: a cell disguised as the current location in the mobile communication network, by transmitting a powerful pilot signal, attracts the terminals around the pseudo base station to the cell of the pseudo base station, and then passes the paging information Notify the terminal of the change of system information, and push different location information (such as location area, routing area or tracking area, etc.) from the original terminal in the system information, so as to induce the terminal to initiate location update (including location area, routing area or tracking area) etc.) process to obtain user privacy information and push information to users.

In the existing mobile communication system, no matter which technical solution, the process of notifying the terminal system information change through the paging process is roughly as follows:

1) First, the network informs all terminals that the paging message needs to be read through the paging indication message. The message can be carried through a specific physical layer paging indication channel (such as the PICH channel in systems such as WCDMA), or through other physical layer channels. (eg PDSCCH in LTE system).

2) After the terminal receives the paging instruction message, it receives the paging message at a specific time. After receiving the paging message, if the message carries the system information change identifier, the terminal needs to read the system information change instruction (mainstream mobile communication technology). is in SIB1).

3) If the value of the newly acquired system information change instruction is inconsistent with the information stored when the terminal read the system information of this cell last time, then re-acquire all system system information, otherwise stop acquiring system information.

4) When the terminal location information (such as location area, routing area or tracking area, etc.) in the newly read system information is inconsistent with the information previously stored by the terminal, the terminal needs to initiate a corresponding location update process to re-register the location information with the network. . The specific process can be illustrated by FIG. 5 .

Based on the mobile communication system implemented by the above solution, as long as the pseudo base station is installed in a suitable location or can dynamically track the information of the cell with the strongest (or best) signal of the mobile station communication network at a specific location, and simulate camouflage, it can be completely realized when the mobile terminal passes through. When the pseudo base station is in the vicinity of the area, attract it to the pseudo base station, and notify the terminal to perform the system information update process through a false paging message, and induce the terminal to initiate the location update process, thereby realizing the acquisition of user information or the push of illegal information. Therefore, the prior art solution does not take this situation into consideration enough, and there is a security loophole.

Through the above analysis, the existing problems and defects in the prior art are: the existing mobile communication system does not take into account the acquisition of user information or the push of illegal information, and there are security loopholes.

The difficulty of solving the above problems and defects is as follows:

To solve the above problems, we must start from the wireless protocol process of the bottom layer of the network and the mobile terminal, and other solutions cannot fully achieve the expected purpose. Therefore, the difficulty of solving this problem is mainly the modification of the wireless protocol of the mobile terminal, especially the modification of the processing flow after the terminal receives the system information update instruction.

The significance of solving the above problems and defects is:

The solution to this problem can be effectively avoided: using the pseudo base station to pretend to be the cell of the current location in the mobile communication network, and by transmitting a powerful pilot signal, the terminals passing around the pseudo base station are attracted to the cell of the pseudo base station, and the terminal is induced to initiate The location update process, thereby illegally acquiring the private information of the mobile terminal user, and pushing illegal information to the user.

SUMMARY OF THE INVENTION

In view of the problems existing in the prior art, the present invention provides a method and system for preventing a terminal from initiating a location update process under a pseudo base station.

The present invention is implemented in this way, a method for preventing a terminal from initiating a location update process under a pseudo base station, and the method for preventing a terminal from initiating a location update process under a pseudo base station includes the following steps:

Step 1, in the mobile communication network, after the terminal receives the system information update instruction through the paging message, if it is found that the cell location information has changed, in order to prevent wrongly camping under the pseudo base station, and it induces the terminal to initiate a location update. process, the location update process is not initiated immediately, and the validity of the change of the cell location information is judged first;

Step 2: Before initiating the location update, start the timer and the counter; for a normal base station, its system information update instruction message will only be sent once or several times, while the pseudo base station will always send the system information update in order to induce the terminal to initiate the location update process. Indication message. Therefore, it can be judged whether the current cell is a cell under the pseudo base station by the number of times the system information update indication message is received within a period of time (for example, 10s).

Step 3: Before initiating the location update, the terminal obtains the neighbor cell list stored when reading the system information last time, re-reads the system information of the neighbor cell based on the neighbor cell list, and broadcasts the information about the neighbor cell system information broadcasted in the neighbor cell system information. The location information of the cell is compared with the location information currently broadcast by the cell. Because the pseudo base station pretends to be the current cell, but because it wants to use the changed location information to induce the terminal to initiate the location update process, the location information broadcast in its system information and the location information of the cell in the neighborhood of the cell stored by the terminal will exist. In the case of inconsistency, this point can be used as a judgment on whether the current cell is a cell under the pseudo base station.

Further, in the step 2, before initiating the location update, starting the timer and the counter includes:

1) If the paging message carrying the system information update instruction received in the timer period exceeds the predetermined threshold, the location update process is not initiated, and the cell reselection process is initiated instead. In a new cell reselection process, The terminal excludes the cell from the list of candidate cells;

2) If the paging message carrying the system information update indication received within the timer period does not exceed the predetermined threshold, the location update process is normally initiated.

Further, before initiating the location update in the step 3, the terminal obtains the neighbor cell list stored when reading the system information last time, re-reads the system information of the neighbor cell based on the neighbor cell list, and uses the neighbor cell system Comparing the location information about the cell broadcasted in the message with the location information currently broadcast by the cell includes:

1) If the location information of the cell broadcast in any neighboring cell is different from the location information currently broadcast by the cell, the location update process is not initiated, and the cell reselection process is initiated instead. In a new cell reselection process, the terminal Exclude the cell from the list of candidate cells;

2) Before initiating the location update, the terminal obtains the neighbor cell list stored when reading the system information last time, re-reads the system information of the neighbor cell based on the neighbor cell list, and broadcasts the information about the neighbor cell system information broadcasted in the neighbor cell system information. The location information of the cell is compared with the location information currently broadcast by the cell; if the location information of the cell broadcast in all neighboring cells is the same as the location information currently broadcast by the cell, the location update process is normally initiated.

Further, after the terminal receives the system information update instruction through the paging message, and it is inconsistent with the information stored after the terminal reads the system information of this cell last time, the following judgment is added when re-reading the system information:

(1) If the cell location information does not change, the terminal does not need to initiate a location update process, then the terminal reads the system information normally and updates the information;

(2) If the cell location information changes, two methods are used for processing; wherein, the cell location information includes a location area, a routing area or a tracking area.

Further, the first method includes: the terminal starts a timer and a counter, and judges:

1) if a timer is used, it is judged whether the paging message carrying the system information update instruction has been received multiple times in the timer period; if it is greater than a certain threshold, the terminal does not initiate a location update process and initiates a cell reselection process;

2) in a new cell selection and reselection process, the terminal excludes the cell from the list of cells to be selected;

3) If the paging message carrying the system information update indication received within the re-timer period is less than the threshold value, the location update process is normally initiated.

Further, the second method includes:

The terminal obtains the neighbor cell list stored when reading the system information last time, re-reads the system information of the neighbor cell based on the neighbor cell list, and transmits the location information about the cell broadcasted in the neighbor cell system information and the current state of the cell. Compare the broadcast location information:

1) if the location information of this cell broadcast in any adjacent cell is different from the location information currently broadcast by this cell, then do not initiate a location update process and initiate a cell reselection process;

2) in a new cell selection and reselection process, the terminal excludes the cell from the list of cells to be selected;

3) If the location information of the cell broadcast in all neighboring cells is the same as the location information currently broadcast by the cell, a location update process is initiated.

Another object of the present invention is to provide a system for preventing a terminal from initiating a location update process under a pseudo base station by implementing the method for preventing a terminal from initiating a location update process under a pseudo base station, and the method for preventing a terminal from initiating a location update process under a pseudo base station The system of the update process includes:

The specific scheme of the present invention is as follows:

After the terminal receives the system information update instruction through the paging message, and it is inconsistent with the information stored after the terminal has read the system information of this cell last time, the following judgment needs to be added when re-reading the system information:

(1) If the cell location information (such as location area, routing area or tracking area, etc.) has not changed, that is, the terminal does not need to initiate a location update process, the terminal reads the system information normally and updates the information.

(2) If the cell location information (such as location area, routing area, or tracking area, etc.) changes, two methods can be used for processing.

A. Method 1: The terminal starts the timer and counter, and further judges:

1) If a timer is used, determine whether the paging message carrying the system information update indication has been received multiple times within the timer period. If it is greater than a certain threshold (for example, 10s, 5 times), the terminal does not initiate the location update process and initiates a location update process. Cell reselection process.

1) If the location information of the cell broadcast in any neighboring cell is different from the location information currently broadcast by the cell, the location update process is not initiated and the cell reselection process is initiated.

2) In a new cell selection and reselection process, the terminal needs to exclude the cell from the list of candidate cells.

3) If the location information of the cell broadcast in all neighboring cells is the same as the location information currently broadcast by the cell, a location update process is initiated.

(3) The two methods described above can be used alone or simultaneously.

The two methods can be illustrated with Figure 3 and Figure 4, respectively.

(2) Start the timer and counter before initiating the location update.

1) If the paging message carrying the system information update instruction received in the timer period exceeds the predetermined threshold, the location update process is not initiated, and the cell reselection process is initiated instead. In a new cell reselection process, The terminal needs to exclude the cell from the list of candidate cells.

2) If the paging message carrying the system information update indication received within the timer period does not exceed the predetermined threshold, the location update process is normally initiated.

(3) Before initiating the location update, the terminal obtains the neighbor cell list stored when the system information was read last time, re-reads the system information of the neighbor cells based on the neighbor cell list, and broadcasts the information about the neighbor cells in the system information of these neighbor cells. The location information of the cell is compared with the location information currently broadcast by the cell.

1) If the location information of the cell broadcast in any neighboring cell is different from the location information currently broadcast by the cell, the location update process is not initiated, and the cell reselection process is initiated instead. In a new cell reselection process, the terminal The cell needs to be excluded from the list of candidate cells.
