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 obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The pseudo base station identification method can be applied to a communication terminal, such as a mobile phone, and the communication terminal can establish communication connection with a base station.
Referring to fig. 1, fig. 1 is a flowchart of an implementation of a pseudo base station identification method according to an embodiment of the present application, where the implementation of the method may include:
step S11: the first mobile communication network is scanned and registered.
The first mobile communication network may be a mobile communication network such as a 4G mobile communication network or a 5G mobile communication network.
Step S12: obtaining a redirection message sent by a first base station of a first mobile communication network; the redirection message is used to guide the communication terminal to register with a second base station of a second mobile communication network having a lower generation level than the first mobile communication network.
Typically, the communication terminal scans and registers with a legitimate base station of the first mobile communication network. In some scenarios, such as a call, a legitimate base station may redirect the communication terminal to a lower-generation mobile communication network. In this case, the communication terminal performs frequency point scanning according to the redirection message, so as to register the communication terminal in a legal base station of the low-generation mobile communication network.
When a pseudo base station exists in the first mobile communication network, the pseudo base station generally transmits larger power to induce the communication terminal to reselect the pseudo base station, but when the mobile communication terminal tries to register to the pseudo base station, the pseudo base station does not establish connection with the communication terminal, but sends a redirection message to the communication terminal to redirect the communication terminal, so that the communication terminal registers to the pseudo base station of the lower-generation mobile communication network. For example, the communication terminal is redirected to a pseudo base station of a 2G mobile communication network or a 3G mobile communication network.
Step S13: it is determined whether the first base station belongs to a pseudo base station based on the redirection message.
Whether the first base station is a pseudo base station can be judged according to the frequency point information or the preset information carried in the redirection message. If the frequency point information or the preset information meets the preset condition, the first base station can be determined to be a pseudo base station, otherwise, the first base station is determined not to be a pseudo base station.
In the embodiment of the application, after the redirection message sent by the base station is received, the frequency point scanning is not directly performed according to the redirection message, but whether the first base station is a pseudo base station is judged based on the redirection message, so that the pseudo base station can be intercepted under the condition that the first base station is determined to be the pseudo base station, and the loss of a user caused by the fact that a communication terminal is redirected to the pseudo base station is avoided.
In an optional embodiment, the above flowchart for determining whether the first base station belongs to the pseudo base station based on the redirection message is shown in fig. 2, and may include:
step S21: at least one parameter included in the redirect message is obtained.
The at least one parameter may be the same type of parameter, for example, all frequency points included in the redirection message are obtained, and the redirection message may include only one frequency point or may include multiple frequency points.
The at least one parameter may also be a different type of parameter.
Step S22: and if the at least one parameter meets the judgment rule, determining the first base station as the pseudo base station.
Wherein, the above-mentioned judgment rule may include: the frequency point is one.
In the embodiment of the present application, if the redirection message includes only one frequency point, the first base station is considered to be a pseudo base station.
In an optional embodiment, another implementation flowchart of determining whether the first base station belongs to the pseudo base station based on the redirection message is shown in fig. 3, and may include:
step S31: check information in the redirect message is obtained.
In this embodiment, when the base station sends the redirection message to the communication terminal, the base station adds the verification information to the redirection message, where the verification information is obtained by encrypting the preset information by using a certain encryption algorithm.
Step S32: and checking the checking information.
After receiving the redirection message, the communication terminal decrypts the verification information according to the decryption algorithm corresponding to the encryption algorithm, judges whether the decrypted information is preset information, if so, the verification is passed, and otherwise, the verification is not passed.
Step S33: and if the verification fails, determining that the first base station is a pseudo base station. And if the verification is passed, determining that the first base station is not a pseudo base station.
In an optional embodiment, another implementation manner of the above determining whether the first base station belongs to the pseudo base station based on the redirection message may be:
scanning the second mobile communication network based on the redirection message, and determining whether the frequency point included in the redirection message belongs to the scanning result; wherein the content of the first and second substances,
if the frequency point included in the redirection message does not belong to the scanning result, determining the first base station as a pseudo base station;
if the frequency point included in the redirection message belongs to the scanning result, determining that the first base station is not a pseudo base station;
the scanning result comprises at least one of the following: the frequency point obtained by scanning the second mobile communication network is carried out aiming at the current position of the electronic equipment; and the frequency point of the second mobile communication network which is connected historically and stored on the electronic equipment.
In this embodiment of the application, when scanning the second mobile communication network, only the frequency point of the second mobile communication network at the current location of the electronic device may be scanned, or only the frequency point of the second mobile communication network historically connected to the electronic device may be scanned, or both the frequency point of the second mobile communication network at the current location of the electronic device and the frequency point of the second mobile communication network historically connected to the electronic device may be scanned.
When the communication terminal scans the frequency points of the second communication network at the current position of the electronic equipment, one or more scanning frequency points with the strongest energy are selected from all the scanned frequency points as a scanning result, and if the frequency points included in the redirection message do not belong to the scanning result, the first base station is considered as a pseudo base station.
The frequency point of the second mobile communication network which is historically connected and stored on the electronic device is usually a legal frequency point, and after the communication terminal scans the frequency point of the second mobile communication network which is historically connected, if the frequency point included in the redirection message does not belong to the scanning result, the communication terminal is not connected with the frequency point included in the redirection message, and the first base station is considered as a pseudo base station.
If the frequency point of the second communication network at the current position of the electronic equipment is scanned and the frequency point of the second mobile communication network historically connected to the electronic equipment is scanned, the first base station is considered to be a pseudo base station when the frequency point included in the redirection message does not belong to the scanning result of scanning the frequency point of the second communication network at the current position of the electronic equipment or the scanning result of scanning the frequency point of the second mobile communication network historically connected to the electronic equipment.
In the above embodiment, it is determined that the first base station is the pseudo base station before the second base station is connected, and based on this, if it is determined that the first base station is the pseudo base station, the response to the redirection message is prohibited, and if it is determined that the first base station is not the pseudo base station, the second base station is connected in response to the redirection message.
In an optional embodiment, the above flowchart of another implementation of determining whether the first base station belongs to the pseudo base station based on the redirection message is shown in fig. 4, and may include:
step S41: scanning the second mobile communication network based on the redirection message, and determining whether the frequency point included in the redirection message belongs to the scanning result; wherein, the scanning result comprises at least one of the following: the frequency point obtained by scanning the second mobile communication network is carried out aiming at the current position of the electronic equipment; and storing the frequency points of the second mobile communication network which is connected historically on the electronic equipment.
Step S42: and if the frequency point included in the redirection message belongs to the scanning result, connecting the second base station based on the frequency point included in the redirection message.
In the embodiment of the application, if the frequency point included in the redirection message belongs to the scanning result, the second base station is connected first. And subsequently judging whether the second base station is a pseudo base station.
Step S43: at least one indicator parameter of a second base station of a second mobile communication network is obtained.
In an alternative embodiment, at least one of the following index parameters may be obtained: minimum access level (q-RxLevMin), minimum access signal quality (q-QualMin-r9), bearer frequency point (dl-CarrierFreq), start scanning frequency point (startingARFCN), GPRS (General Packet Radio Service) configuration information, and the like. The index parameter may be read from a SIB (System Information Block) message.
Step S44: and determining whether the second base station is a fake base station based on the obtained at least one index parameter and a fake base station judgment standard of the second mobile communication network.
In an optional embodiment, each acquired index parameter may be compared with a corresponding normal range, and if the first index parameter is located in the corresponding normal range, it indicates that the first index parameter is normal, otherwise, it indicates that the first index parameter is abnormal, where the first index parameter is any one of the at least one index parameter.
For example, the normal minimum access level is typically between-62 and-64, while the minimum access level of a pseudo base station is typically lower, e.g., -65. The normal minimum access signal quality is typically set around-18, -19, while the pseudo base station is typically set lower, e.g. -25. The bearing frequency point of the normal base station is within the preset range, and the bearing frequency point of the pseudo base station is outside the preset range. The frequency point scanning range of the normal base station is larger, and the frequency point scanning range of the pseudo base station is smaller, so the frequency point for starting scanning of the pseudo base station is usually larger than the frequency point for starting scanning of the normal base station. The normal base stations will configure the GPRS information in the SIB message, while the pseudo base stations will most likely not.
If at least two index parameters are abnormal, the second base station can be considered as a pseudo base station, otherwise, the second base station is not considered as the pseudo base station.
Step S45: and if the second base station is the pseudo base station, determining that the first base station is the pseudo base station.
If the second base station is not a pseudo base station, determining that the first base station is not a pseudo base station;
in an optional embodiment, the above flowchart for determining whether the first base station belongs to the pseudo base station based on the redirection message is shown in fig. 5, and may include:
step S51: at least one parameter included in the redirect message is obtained.
Step S52: if the at least one parameter meets the judgment rule, connecting a second base station based on the frequency point included by the redirection message; wherein the judgment rule includes: the frequency point is one.
Different from the embodiment shown in fig. 2, in the embodiment of the present application, if there is only one frequency point in the redirection message, it is considered that the first base station may be a pseudo base station. Then the second base station is connected first, and whether the second base station is a pseudo base station is judged subsequently.
Step S53: at least one indicator parameter of a second base station of a second mobile communication network is obtained.
In an alternative embodiment, at least one of the following index parameters may be obtained: minimum access level (q-RxLevMin), minimum access signal quality (q-QualMin-r9), bearer frequency point (dl-CarrierFreq), start scanning frequency point (startingARFCN), GPRS (General Packet Radio Service) configuration information, and the like. The index parameter may be read from a SIB (System Information Block) message.
Step S54: and determining whether the second base station is a fake base station or not based on the at least one index parameter and a fake base station judgment standard of the second mobile communication network.
In an optional embodiment, each acquired index parameter may be compared with a corresponding normal range, and if the first index parameter is located in the corresponding normal range, it indicates that the first index parameter is normal, otherwise, it indicates that the first index parameter is abnormal, where the first index parameter refers to any one of the at least one index parameter.
For example, the normal minimum access level is typically between-62 and-64, while the minimum access level of a pseudo base station is typically lower, e.g., -65. The normal minimum access signal quality is typically set around-18, -19, while the pseudo base station is typically set lower, e.g. -25. The bearing frequency point of the normal base station is within the preset range, and the bearing frequency point of the pseudo base station is outside the preset range. The frequency point scanning range of the normal base station is larger, and the frequency point scanning range of the pseudo base station is smaller, so the frequency point for starting scanning of the pseudo base station is usually larger than the frequency point for starting scanning of the normal base station. The normal base stations will configure the GPRS information in the SIB message, while the pseudo base stations will most likely not.
Since it is highly likely that the first base station is the pseudo base station in step S52, in this embodiment, the determination criterion of the pseudo base station may be relaxed: if at least one index parameter is abnormal, the second base station can be considered as a pseudo base station, otherwise, the second base station is not considered as the pseudo base station. For example, if the GPRS configuration information is not acquired, the second base station is considered to be a pseudo base station.
Step S55: and if the second base station is the pseudo base station, determining that the first base station is the pseudo base station.
If the second base station is not a pseudo base station, determining that the first base station is not a pseudo base station.
In the embodiments shown in fig. 4 or fig. 5, after connecting to the second base station, it is determined whether the first base station is a pseudo base station, and based on this, if the first base station is determined to be a pseudo base station, the third base station connecting to the first mobile communication network is resumed. If it is determined that the first base station is not a pseudo base station, the connection of the second base station is maintained.
In an optional embodiment, if it is determined that the second base station is a pseudo base station, the frequency point used by the second base station to be connected to is prohibited from being used as the frequency point of the second mobile communication network historically connected to the electronic device, that is, even if the frequency point used by the second base station to be connected to is already added to the frequency point sequence of the second mobile communication network historically connected to the electronic device before the second base station is determined to be the pseudo base station, after the second base station is determined to be the pseudo base station, the frequency point used by the second base station to be connected to is deleted from the frequency point sequence.
