Detailed ways

In order to enable those in the technical field to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

With the rapid development of mobile communication technology, mobile communication has experienced the development of multiple versions such as 2G, 3G and 4G. Whether it is the GSM (Global System for Mobile Communication) mobile communication system or CDMA (Code Division Multiple Access) communication system in the early 2G era, or the LTE (long term evolution, long term evolution) system architecture in the later 4G era, base stations are A relatively important communication device.

For example, the 2G mobile communication system architecture diagram is shown in Figure 1. The BTS base station 99 (Base StationController) serves as the access device of the mobile communication network and is connected to the base station controller 98, and then the base station controller 98 is connected to the mobile switching center 97, and the mobile switching center 97 will also be connected to the public switched telephone network 96, etc. connect. Another example is the 4G mobile communication system architecture diagram shown in Figure 2. The eNB base station 95 is connected to the MME (Mobility Management Entity), that is, the mobility management node 94, and the MME is connected to the service gateway 93. The service gateway 93 is connected to the packet data gateway 92, and the packet data gateway 92 is connected to the packet data network 91. It can be seen from Figures 1 and 2 that in the mobile communication system, the base station, as a device that directly establishes a connection with the mobile terminal, plays an important role in the entire system architecture. Base stations generally refer to "public mobile communication base stations", which are mainly used to provide signals to mobile terminals such as mobile phones and tablet computers. With the development of communication technology, the inventor discovered that pseudo base stations appeared.

Pseudo base stations are illegal base stations outside the mobile communication network. Pseudo base stations are generally composed of hosts and laptops. They can be searched within a certain radius centered on it through SMS group senders, SMS senders and other related equipment. Mobile phone card information, taking advantage of the flaws of 2G mobile communications, pretending to be the operator's base station, pretending to use other people's mobile phone numbers to forcefully send short messages such as fraud and advertising promotions to users' mobile phones.

When the pseudo base station equipment is running, the wireless signal sent by the mobile terminal is forcibly connected to the equipment, causing the mobile terminal to be unable to use the services provided by the operator normally. The mobile terminal will generally be temporarily disconnected from the network for 8 to 12 seconds and then return to normal. Some mobile terminals You must power on and off to reconnect to the network. In addition, it will also cause mobile terminal users to frequently update their locations, which will strain wireless network resources in the area and cause network congestion, affecting users' normal communications.

In response to the above problems, the inventor has conducted long-term research and proposed a pseudo base station processing method, device, mobile terminal and storage medium provided in the embodiments of the present application. When the mobile terminal is attacked by a pseudo base station, the connection with the pseudo base station is disconnected. And connect to the target base station to send alarm information, and after sending the alarm information, log out of the network and enter flight mode to reduce the probability of attacks by pseudo base stations on mobile terminals and improve the information security of mobile terminals.

Example

Please refer to Figure 3. Figure 3 shows a schematic flow chart of a pseudo base station processing method provided by an embodiment of the present application. The pseudo base station processing method is used to disconnect the mobile terminal from the pseudo base station when it is attacked by the pseudo base station. And connect to the target base station to send alarm information, and after sending the alarm information, log out of the network and enter flight mode to reduce the probability of attacks by pseudo base stations on mobile terminals and improve the information security of mobile terminals. In a specific embodiment, the pseudo base station processing method is applied to the pseudo base station processing device 200 as shown in Figure 11 and the mobile terminal 100 (Figure 12) configured with the pseudo base station processing device 200. In the following, the mobile terminal An example is used to describe the specific process of this embodiment. Of course, it can be understood that the mobile terminal applied in this embodiment can be a smart phone, a tablet computer, a wearable electronic device, etc., and is not specifically limited here. The process shown in Figure 3 will be described in detail below. The pseudo base station processing method may specifically include the following steps:

Step S110: When detecting that the mobile terminal is attacked by a pseudo base station, disconnect the mobile terminal from the pseudo base station and try to access the target base station.

Generally, the network air interface is used to realize information interaction between the mobile terminal and the base station of the mobile communication network, and the information on the network air interface is carried by various logical channels. Among them, logical channels are divided into two categories: traffic channel (TCH, Traffic Channel) and control channel (CCH, Control Channel). Among them, TCH is mainly used to transmit services between the network and mobile terminals, such as voice, data, etc.; CCH is used A channel for transmitting signaling information and short packet data. The Broadcast Channel (BCH) in CCH is used to transmit information by broadcasting. The Broadcast Control Channel (BCCH) in BCH is used by the base station to transmit information to the base station. The mobile terminal broadcasts public information, such as system messages, etc. Therefore, the mobile terminal can detect the base station by monitoring the broadcast information of the base station, and register with the base station according to the detection result.

However, the base station detected by the mobile terminal may include a pseudo base station. Therefore, the mobile terminal may register with the pseudo base station and be attacked by the pseudo base station. Therefore, as a way, it can be determined whether the base station registered by the mobile terminal is a pseudo base station. For example, the mobile terminal can obtain the broadcast information of the base station and extract the identification information of the base station from the broadcast information. The identification information determines whether the base station is a pseudo base station. Specifically, the identification information may include the cell location area (TAC, tracking area), location area code (LAC, location area code), cell identity (CID, cell identity), etc. of the base station cell corresponding to the base station. Therefore, as a method, when the mobile terminal detects a new base station, it can calculate the difference between the TAC/LAC/CID of the base station cell corresponding to the base station and the TAC/LAC/CID of the base station cell that the mobile terminal has recently successfully registered. If If the difference is greater than the set threshold, it can be determined that the base station detected by the mobile terminal is a pseudo base station.

In this embodiment, when it is determined that the base station detected by the mobile terminal is a pseudo base station, whether the mobile terminal is attacked by the pseudo base station can be monitored. As a way, whether the mobile terminal is attacked by the pseudo base station can be monitored. Monitoring methods may include real-time monitoring, predetermined interval monitoring, or user-set detection methods, etc., which are not limited here. When it is detected that the mobile terminal is attacked by the pseudo base station, the mobile terminal responds to the pseudo base station attack. As a way, the mobile terminal can disconnect from the pseudo base station and try to access the target base station. Specifically, when a mobile terminal is attacked by a pseudo base station, it means that the pseudo base station has obtained the user's IMSI, TMSI and other communication information keys, and another mobile terminal can be used to replace the mobile terminal to interact with the operator's network and receive verification. SMS, etc., and then steal account funds. Therefore, in order to protect the property safety of mobile terminal users, the mobile terminal can disconnect from the pseudo base station and try to access the target base station to use the network normally. On the one hand, it can avoid pseudo base stations. Attacks on the base station, on the other hand, can send out alarm messages after normal use of the network.

Step S120: When the mobile terminal successfully accesses the target base station, send an alarm message.

As a way, after the mobile terminal disconnects from the pseudo base station, it can re-detect the base stations around it, and select a base station for registration according to the detection results. It is understandable that the base station to which the mobile terminal re-registers may be a pseudo base station. , may not be a pseudo base station. Therefore, the mobile terminal can detect whether the detected base station or the registered base station is a pseudo base station. When it is detected that the detected or registered base station is not a pseudo base station, it can determine whether the base station is a pseudo base station. If the mobile terminal successfully accesses the target base station, that is to say, when the mobile terminal is connected to a certain base station and can use the network normally, it means that the mobile terminal successfully accesses the target base station.

Furthermore, when the mobile terminal successfully accesses the target base station, indicating that the mobile terminal can use the network normally, the mobile terminal can send an alarm message to the public security agency to inform the public security agency of the attack time, attack location, and attack time of the pseudo base station through the alarm message. method and other characteristic information, etc., so that the public security organs can remove fake base stations based on the alarm information of mobile terminals and report the information security of mobile terminal users. The alarm information may include an alarm phone number and/or an alarm text message.

As an implementation manner, when the mobile terminal successfully accesses the target base station, the mobile terminal can automatically generate alarm information, for example, automatically edit the alarm text message or automatically jump to the alarm phone dialing interface, and then send a query message to ask the user whether To issue the alarm information, it can be understood that when an operation indicating confirmation of issuing the alarm information is detected, the mobile terminal will send the alarm information to the public security agency in response; when an operation indicating confirmation not to issue the alarm information is detected, the mobile terminal During operation, the mobile terminal deletes the alarm information in response.

Step S130: Control the mobile terminal to log out of the network and enter airplane mode.

Specifically, since there are pseudo base stations in the area where the mobile terminal is located, and the pseudo base stations generally attack the mobile terminal through the 2G network or 3G network, the mobile terminal may be attacked by the pseudo base station again at any time while using the network in the area. Therefore, in order to prevent the mobile terminal from being attacked by the pseudo base station again, the mobile terminal can be controlled to log off the network and enter flight mode, thereby preventing the pseudo base station from attacking the mobile terminal through the 2G network or 3G network and improving the information security of the mobile terminal. .

The pseudo base station processing method provided by an embodiment of the present application, when detecting that a mobile terminal is attacked by a pseudo base station, disconnects from the pseudo base station and attempts to access the target base station. When the mobile terminal successfully accesses the target base station, it sends Alarm information, control the mobile terminal to log off the network and enter flight mode, thereby disconnecting the mobile terminal from the pseudo base station and connecting to the target base station to send alarm information when detecting that the mobile terminal is attacked by a pseudo base station, and then log off the network after sending the alarm information Enter flight mode to reduce the probability of attacks by pseudo base stations on mobile terminals and improve the information security of mobile terminals.

Please refer to Figure 4. Figure 4 shows a schematic flowchart of a pseudo base station processing method provided by yet another embodiment of the present application. The process shown in Figure 4 will be described in detail below. The pseudo base station processing method shown may specifically include the following steps:

Step S210: When it is detected that the mobile terminal is attacked by a pseudo base station, obtain the characteristic parameters of the pseudo base station.

In this embodiment, when it is determined that the mobile terminal is attacked by a pseudo base station, the characteristic parameters of the pseudo base station can be obtained, where the characteristic parameters can include a tracking area identifier (TAI), an absolute video channel number (EARFCN, eutra absolute radio frequency channel number), physical cell identity (PCI, physical cell identity) and cell identity (CID, cell identity). Of course, the characteristic parameters corresponding to the pseudo base station may also include other parameters, I won’t go into details here. It can be understood that the characteristic parameters can be used to identify pseudo base stations, where one characteristic parameter can correspond to multiple base stations. Therefore, when the characteristic parameters of a certain base station are consistent with the characteristic parameters of the pseudo base station, it can be considered that the characteristic parameter is consistent with the characteristic parameter of the pseudo base station. A certain base station is also a pseudo base station.

Step S220: Prohibit the mobile terminal from accessing the base station corresponding to the characteristic parameter.

It can be understood that since the base station corresponding to the characteristic parameter may be a pseudo base station, in order to reduce or even avoid the possibility of the mobile terminal accessing the pseudo base station and being attacked by the pseudo base station, the mobile terminal may be prohibited from accessing the base station corresponding to the characteristic parameter. of all base stations. That is to say, the mobile terminal can obtain the characteristic parameters corresponding to all detected base stations, and then compare the characteristic parameters of the detected base stations with the characteristic parameters of the pseudo base station to determine whether the characteristic parameters of the detected base stations are the same as those of the pseudo base stations. Whether the characteristic parameters of the pseudo base station are consistent, it is understandable that when the characteristic parameters of the detected base station are consistent with the characteristic parameters of the pseudo base station, it is determined that the base station detected by the mobile terminal may be a pseudo base station, and the mobile terminal is prohibited from accessing the base station. ; When the characteristic parameters of the detected base station are inconsistent with the characteristic parameters of the pseudo base station, it is determined that the base station detected by the mobile terminal is not a pseudo base station or the probability of the pseudo base station is low, and the mobile terminal is allowed to access the base station.

Step S230: Try to access the target base station corresponding to other characteristic parameters except the characteristic parameters.

Further, the base stations detected by the mobile terminal are analyzed to obtain the characteristic parameters of each base station, and a base station whose characteristic parameters are consistent with the characteristic parameters of the pseudo base station is obtained, and then attempts to access the detected base station except that the characteristic parameters are consistent with those of the pseudo base station. In addition to the base stations with consistent characteristic parameters of the pseudo base station, target base stations corresponding to other characteristic parameters reduce the possibility of mobile terminals accessing the pseudo base station.

For example, assume that the characteristic parameter of the pseudo base station is N1, and the base stations detected by the mobile terminal include base station A1, base station A2, base station A3 and base station A4, the characteristic parameter of base station A1 is N1, and the characteristic parameter of base station A2 is N2, The characteristic parameter of base station A3 is N1, and the characteristic parameter of base station A4 is N3. Then, it can be determined that the characteristic parameters of base station A1 and base station A3 are consistent with the characteristic parameters of the pseudo base station, and then the base station A1 and base station A3 may also be pseudo base stations. At the same time, it can be determined that the characteristic parameters of base station A2 and base station A4 are consistent with the characteristics of the pseudo base station. If the parameters are inconsistent, the base station A2 and the base station A4 are not pseudo base stations or have a low probability of being pseudo base stations. Therefore, the mobile terminal can be controlled to try to access the base station A2 or the base station A4, thereby reducing the possibility of the mobile terminal accessing the pseudo base station.

Step S240: When the mobile terminal successfully accesses the target base station, send alarm information including characteristic parameters of the pseudo base station.

As a way, the alarm information sent by the mobile terminal may include the characteristic parameters of the pseudo base station, such as the location area identification (TAI, Tracking Area Identity), the absolute video channel number (EARFCN, eutra absolute radiofrequency channel number), the physical unit identification ( At least one of PCI, physical cell identity) and cell identity (CID, cell identity) to facilitate the public security agency to quickly locate the pseudo base station and handle it in a timely manner.

Step S250: Control the mobile terminal to log out of the network and enter airplane mode.

As an implementation manner, after controlling the mobile terminal to log off the network and enter flight mode, the mobile terminal can record at least one of the characteristic parameters corresponding to the pseudo base station, the attack time of the pseudo base station, and the alarm information of the mobile terminal, and then based on the pseudo base station The corresponding characteristic parameters, the attack time of the pseudo base station, and the alarm information generation prompt information of the mobile terminal are output through the mobile terminal, wherein the prompt information can be output by displaying it on the mobile terminal or outputting it by voice broadcasting by the mobile terminal. etc., no limitation is made here.

Step S260: Detect the duration for which the mobile terminal enters the flight mode.

In this embodiment, after the mobile terminal is controlled to enter the flight mode, the duration of the mobile terminal entering the flight mode is monitored and recorded. The monitoring method may include real-time monitoring, predetermined time interval monitoring, or based on the user's setting. Time interval monitoring is optional. In order to improve the accuracy of the monitoring duration, real-time monitoring can be used.

Step S270: Determine whether the duration is greater than the preset duration.

As a method, the mobile terminal sets a preset duration, which is used as a basis for judging the duration of the mobile terminal entering the flight mode. It can be understood that the preset duration can be stored locally by the mobile terminal in advance, or it can be determined during the judgment. Set it again when necessary, and there is no limit here. The preset duration can be automatically configured by the mobile terminal, can be manually set by the user corresponding to the mobile terminal, or can be configured by a server connected to the mobile terminal and then sent to the mobile terminal, which is not limited here. Further, after obtaining the duration for the mobile terminal to enter the flight mode, the duration is compared with the preset duration to determine whether the duration is greater than the preset duration.

Step S280: When the duration is greater than the preset duration, control the mobile terminal to exit the airplane mode and access the network.

It can be understood that when the duration is longer than the preset duration, it can be considered that the pseudo base station has been processed or the mobile terminal has left the area where the pseudo base station is located within the duration. Therefore, the mobile terminal can be controlled to exit the flight mode and access the network normally. , to ensure the normal use of the mobile terminal.

As another method, you can first obtain the location information of the mobile terminal when it enters the flight mode, detect the location information of the mobile terminal after it enters the flight mode, and combine the location information of the mobile terminal after it enters the flight mode and the position of the mobile terminal when it enters the flight mode. The information is compared to obtain the difference between the position information of the mobile terminal after entering flight mode and the position information when entering flight mode, and then the difference is compared with the preset difference value set in advance, where, when When the difference is greater than the preset difference, it means that the mobile terminal has moved out of the range covered by the pseudo base station after entering flight mode, and the mobile terminal can be controlled to exit flight mode and access the network; when the difference is not greater than the preset The difference indicates that the mobile terminal has not moved or moved out of the range covered by the pseudo base station after entering the flight mode, and the mobile terminal is controlled to maintain the flight mode to avoid being attacked by the pseudo base station again.

Another embodiment of the present application provides a pseudo base station processing method. When it is detected that a mobile terminal is attacked by a pseudo base station, the characteristic parameters of the pseudo base station are obtained, the mobile terminal is prohibited from accessing the base station corresponding to the characteristic parameter, and attempts to access the base station other than the pseudo base station. The target base station corresponding to characteristic parameters other than the characteristic parameters, when the mobile terminal successfully accesses the target base station, sends an alarm message including the characteristic parameters, controls the mobile terminal to log off the network and enters flight mode, and detects that the mobile terminal logs off the network and enters flight mode. time length, and determine whether the time length is greater than the preset time length. When the time length is greater than the preset time length, control the mobile terminal to exit the airplane mode and access the network. Compared with the pseudo base station processing method shown in Figure 3, this embodiment reduces the probability of the mobile terminal accessing the pseudo base station by prohibiting the base station corresponding to the characteristic parameter of the pseudo base station, and by prohibiting the mobile terminal from entering flight mode for longer than When the preset time is reached, exit airplane mode and access the network to ensure normal network use of the mobile terminal.

Please refer to FIG. 5 , which shows a schematic flowchart of a pseudo base station processing method provided by yet another embodiment of the present application. The process shown in Figure 5 will be described in detail below. The pseudo base station processing method shown may specifically include the following steps:

Step S310: When it is detected that the mobile terminal is attacked by a pseudo base station, the mobile terminal is prohibited from accessing the 2G network and the 3G network.

Usually, fake base stations take advantage of the technical flaws of the 2G network or 3G network to pretend to be the operator's base station and use other people's mobile phone numbers to forcefully send fraud, advertising and other text messages to users' mobile phones. In this embodiment, when it is detected that the mobile terminal is attacked by a pseudo base station, it indicates that the mobile terminal is currently in a state of accessing the 2G network or 3G network. Therefore, in order to eliminate the attack of the pseudo base station on the mobile terminal, the mobile terminal can be prohibited from accessing the 2G network or 3G network. into the 2G network and 3G network, thereby prohibiting pseudo base stations from using the technical flaws of the 2G network or 3G network to attack mobile terminals, and preventing mobile terminals from registering on the pseudo base stations.

Step S320: Try to access the 4G network and enter VOLTE mode.

Furthermore, since most of the pseudo base stations used by illegal elements are 2G and 3G networks, and only a few pseudo base stations are used in 4G networks, for example, the pseudo base stations used by security monitoring systems are 4G networks, but this This kind of pseudo base station is used for security monitoring of mobile terminals and will not cause property losses to mobile terminal users. Therefore, as a way, after prohibiting mobile terminals from accessing 2G networks and 3G networks, the mobile terminals can be set to connect to 4G The network enters VOLTE mode, where VOLTE stands for Voice over LTE and is an IMS-based voice service. It is an IP data transmission technology that does not require a 2G network/3G network. All services are carried on the 4G network, which can realize the unification of data and voice services under the same network. Specifically, within a specified period of time, the mobile terminal is always connected to the 4G network and is not allowed to switch to the state of connecting to the 2G network and 3G network. Therefore, it is possible to prevent pseudo base stations used by criminals from attacking mobile phones through the 2G network or 3G network. terminal, and at the same time allow mobile terminals to access the Internet normally.

It should be noted that the mobile terminal can also enter the IMS mode, where the IMS mode includes VOLTE mode, VOWIFI mode, even VO5G mode, etc., and is not limited here.

Step S330: When the mobile terminal successfully accesses the target base station, send an alarm message.

Further, when it is determined that the mobile terminal successfully accesses the 4G network, it can be considered that the mobile terminal successfully accesses the target base station, and the mobile terminal sends an alarm message in response.

Step S340: Control the mobile terminal to log out of the network and enter airplane mode.

Step S350: Detect the duration for which the mobile terminal enters the flight mode.

Step S360: Determine whether the duration is greater than the preset duration.

Step S370: When the duration is greater than the preset duration, control the mobile terminal to exit the airplane mode and access the network.

Another embodiment of the present application provides a pseudo base station processing method. When detecting that a mobile terminal is attacked by a pseudo base station, the mobile terminal is prohibited from accessing the 2G network and the 3G network, and attempts to access the 4G network to enter the VOLTE mode. After the mobile terminal successfully accesses When the target base station is targeted, an alarm message is issued, the mobile terminal is controlled to log off the network and enter flight mode, the duration of the mobile terminal entering flight mode is detected, and whether the duration is greater than the preset duration is determined. When the duration is greater than the preset duration, the mobile terminal is controlled to exit flight mode. and access the network. Compared with the pseudo base station processing method shown in Figure 3, this embodiment reduces the probability of the mobile terminal accessing the pseudo base station by prohibiting the mobile terminal from entering the 2G network and 3G network and trying to access the 4G network. When the flight mode duration is longer than the preset duration, exit the flight mode and access the network to ensure normal network use of the mobile terminal.

Please refer to FIG. 6 , which shows a schematic flowchart of a pseudo base station processing method provided by another embodiment of the present application. The process shown in Figure 6 will be described in detail below. The pseudo base station processing method shown may specifically include the following steps:

Step S410: Monitor the network connection status of the mobile terminal.

In this embodiment, the network connection status of the mobile terminal is first monitored. It can be understood that the network connection status of the mobile terminal may include a connected state and a non-connected state, where the non-connected state includes a non-connected state and a connected state. medium state. As a way, you can determine whether the mobile terminal is in the network connection state by checking the status value of the mobile terminal. Specifically, in one embodiment, when the mobile terminal is in the network connection state, the mobile terminal can generate the first Status value: When the mobile terminal is in a non-network connection state, the mobile terminal can generate a second status value, so that the network connection status of the mobile terminal can be monitored by monitoring the first status value and the second status value.

In addition, after it is determined that the mobile terminal is in a network connection state, changes in the network to which the mobile terminal is connected can also be monitored, for example, monitoring whether the mobile terminal drops from the network, and whether the mobile terminal drops from a resident cell to a non-resident cell. Monitoring, monitoring whether the mobile terminal falls from the original cell to the new cell, etc. are not limited here.

Step S420: When the mobile terminal drops from a resident cell to a non-resident cell and receives the target text message, it is determined that the mobile terminal is attacked by a pseudo base station.

When it is detected that the mobile terminal falls from the resident cell to the non-resident cell, whether the mobile terminal receives the text message is detected. Wherein, if the mobile terminal falls from the resident cell to the non-resident cell and receives the text message, the text message is Recognition is performed to determine whether the text message is a target text message. In this embodiment, when the text message is a target text message, it can be determined that the mobile terminal is attacked by a pseudo base station. When the text message is not a target text message, it can be determined that the mobile terminal is not attacked by a pseudo base station. Attacked by fake base station.

As an implementation manner, when a mobile terminal drops from a resident cell to a non-resident cell and receives a text message, it performs word segmentation on the content of the text message to obtain multiple word segmentation results, and then determines whether the multiple word segmentation results include the target key. word, wherein when multiple word segmentation results include the target keyword, it can be determined that the text message received by the mobile terminal is the target text message. In this embodiment, the target keyword may include at least one of account login, password modification, verification code, and transfer. For example, the text message content is "You applied for mobile phone number registration on **year**month**, and the verification code is 000000." Then, as a way, segmenting the text message content can obtain "you" , "at", "**year**month**project", "applied", "mobile phone", "number", "registration", "verification code", "yes", "000000", and then divide the words The results are compared with the pre-stored target keywords to determine whether the word segmentation results contain the target keywords.
