In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments 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 system or the CDMA (Code Division Multiple Access) communication system in the early 2G era, or the LTE (long term evolution) system architecture in the 4G era, the base stations are A more important communication device.

For example, a schematic diagram of the architecture of the 2G mobile communication system shown in FIG. 1. The BTS base station 99 (Base Station) is connected to the base station controller 98 as an access device for mobile communication, and then the base station controller 98 is connected to the mobile switching center 97, and the mobile switching center 97 is also connected to the public switched telephone network 96 Wait for connection. Another example is the schematic diagram of the 4G mobile communication system architecture shown in FIG. 2. The eNB base station 95 is connected to an MME (Mobility Management Entity), that is, a mobile management node 94, and the MME is connected to a service gateway 93, which is then connected to a packet data gateway 92, and the packet data gateway 92 is connected to a packet data network 91. It can be seen from FIGS. 1 and 2 that in the mobile communication system, the base station, as a device that directly establishes a connection with the mobile terminal, has a relatively important position in the entire system architecture. A base station generally refers to a "public mobile communication base station", and its role is 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 station is a fake base station, which is an illegal base station outside the mobile communication network. The pseudo base station is generally composed of a host computer and a notebook computer. It can be retrieved through a SMS group sender, a SMS sender and other related equipment within a certain radius. Mobile phone card information, using the deficiencies of 2G mobile communication, by disguising as the base station of the operator, using the mobile phone number of others to forcibly send short messages such as fraud and advertising to the user's mobile phone.

When the pseudo base station device is running, the wireless signal sent by the mobile terminal is forced to connect to the device, resulting in the mobile terminal not being able to use the services provided by the operator normally. The mobile terminal will temporarily go offline for 8 to 12 seconds and return to normal. Some mobile terminals Then you must switch on and off to reconnect to the network. In addition, it will cause mobile terminal users to frequently update their locations, making the wireless network resources in this area tight and causing network congestion, affecting the user's normal communication.

In response to the above problems, the inventors have conducted long-term research and proposed the cell interference detection method, device, mobile terminal, and storage medium provided by the embodiments of the present application. By detecting and determining the target cell’s performance in the first time period and the second time period The change range of the signal value determines whether the target cell is interfered with and prevents it, so as to improve the safety of the mobile terminal. The specific cell interference detection method will be described in detail in subsequent embodiments.

Examples

Please refer to FIG. 3, which is a schematic flowchart of a cell interference detection method according to an embodiment of the present application. The cell interference detection method is used to determine whether the target cell is interfered with and prevent it by improving the security of the mobile terminal by detecting and judging the change range of the signal value of the target cell in the first time period and the second time period. In a specific embodiment, the cell interference detection method is applied to the cell interference detection device 200 shown in FIG. 7 and the mobile terminal 100 (FIG. 8) configured with the cell interference detection device 200. As an example, the specific process of this embodiment will be described. Of course, it can be understood that the mobile terminal applied in this embodiment may be a smart phone, a tablet computer, a wearable electronic device, etc., which is not specifically limited herein. The flow shown in FIG. 3 will be described in detail below. The cell interference detection method may specifically include the following steps:

Step S101: Detect the first signal value of the target cell within the first time period.

In this embodiment, the target cell may be regarded as a cell currently serving as a cell of the mobile terminal, and the target cell has a coverage area, and the coverage area refers to the coverage of the signal of the base station corresponding to the target cell Area, when the mobile terminal is located in the coverage area, the target cell can be selected as the cell to be served. It can be understood that the coverage areas of different base stations corresponding to different cells may have overlapping areas or may be independent of each other.

As a way, before entering the network, the mobile terminal needs to detect the base station in the area where it is located in order to demodulate and access the detected base station. Generally, the mobile terminal is provided with a network air interface, which is used to implement 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 major categories: traffic channels (TCH, Traffic) and control channels (CCH, Control). Among them, TCH mainly transmits services between the network and mobile terminals, such as voice and data; CCH is used For transmitting signaling information and short packet data channels, the broadcast channel (BCH, Broadcast) in CCH is used to transmit information by broadcast, and the broadcast control channel (BCCH, Broadcast) in BCH is used by the base station to Mobile terminals broadcast common information, such as system messages.

Therefore, the mobile terminal can detect the base station by monitoring the broadcast information of the base station and monitor the cell corresponding to the detected base station. Optionally, the mobile terminal monitors the target cell corresponding to the detected base station . Specifically, in this embodiment, the first signal value of the target cell is detected within a first time period, wherein the duration of the first time period may be automatically set by the mobile terminal or manually set by the user, In addition, the first signal value can be detected in real time within the first time period, or the first signal value can be detected at preset time intervals, which is not limited herein.

As a first manner, the first signal value includes a first received signal strength indicator, where the first received signal strength indicator is a received signal strength indicator (Received Signal Strength Indication, RSSI) in the target cell within a first time period ), where the received signal strength indicator is used to characterize the received broadband power, including thermal noise and receiver-generated noise within the bandwidth defined by the receiver pulse forming filter. The measurement reference point is the antenna port of the UE, that is, the received signal strength indicator is the average power of all signals (including pilot signals and data signals, neighboring cell interference signals, noise signals, etc.) in the received symbol.

As a second way, the first signal value further includes a first signal-to-noise-interference power ratio, where the first signal-to-noise-interference power ratio is the signal-to-noise-interference power ratio of the target cell in the first time period ( signal to noise plus interference (ratio, SNIR), where the signal-to-noise interference power ratio is used to characterize the total signal power ratio (noise + interference).

As a third manner, the first signal value further includes a first reference signal reception quality, where the first reference signal reception quality is the reference signal reception quality of the target cell within a first time period (ReferenceSignalReceiving Quality (RSRQ), where the reference signal reception quality is defined as the ratio N×RSRP/(E-UTRA carrier RSSI), where N represents the number of RBs in the E-UTRA carrier RSSI measurement bandwidth. The numerator and denominator should be obtained on the same resource block. E-UTRA carrier received signal field strength indication (E-UTRA carrier RSSI), the linear average of the total received power (in W) observed by the UE from all sources, including common channel services and non-cell services, neighbors Regional channel interference, thermal noise, etc.

Step S102: Detect the second signal value of the target cell within a second time period, where the second time period is later than the first time period.

Further, the second signal value of the target cell is detected within a second time period, where the second time period is later than the first time period, and it is understandable that the first time period and the second time period It may be a continuous time period or a discontinuous time period, which is not limited herein. As a first method, the second signal value includes a second received signal strength indicator, where the second received signal strength indicator is a received signal strength indicator (Received Signal Strength Indication, RSSI) of the target cell within a second time period . As a second way, the second signal value further includes a second signal-to-noise-interference power ratio, where the second signal-to-noise-interference power ratio is the signal-to-noise-interference power ratio of the target cell in the second time period ( signal to noise plus interference power ratio (SNIR). As a third mode, the second signal value further includes a second reference signal reception quality, where the second reference signal reception quality is the reference signal reception quality of the target cell within a second time period (ReferenceSignalReceiving Quality, RSRQ).

Step S103: determine whether the first signal value satisfies the first range, and determine whether the second signal value satisfies the second range, wherein the maximum value of the second range is greater than the maximum value of the first range, The minimum value of the second range is smaller than the minimum value of the first range.

In this embodiment, the mobile terminal is provided with a first range and a second range, wherein the first range is used as a basis for determining the first signal value, and the second range is used for determining the second signal value According to, as a way, the first range and the second range may be preset by the mobile terminal and stored locally, may be preset by the server and transmitted to the mobile terminal and stored locally, or may be obtained online from the server when judging, No limitation here. The maximum value of the second range is greater than the maximum value of the first range, and the minimum value of the second range is less than the minimum value of the second range. For example, the second range is (-5,5), The first range is (-4, 4) and so on.

Further, after obtaining the first signal value of the target cell, the first signal value is compared with the first range to determine whether the first signal value is within the first range, wherein, when the first When the signal value is within the first range, it is determined that the first signal value satisfies the first range; when it is determined that the first signal value is not within the first range, it is determined that the first signal value does not satisfy the first range. As a first way, when the first signal value includes the first received signal strength indicator, the first received signal strength indicator is compared with the first range to determine whether the first received signal strength indicator meets the first range. As a second way, when the first signal value includes the first signal-to-noise-interference power ratio, the first signal-to-noise-interference power ratio is compared with the first range to determine whether the first signal-to-noise-interference power ratio meets The first range. As a third way, when the first signal value includes the first reference signal reception quality, the first reference signal reception quality is compared with the first range to determine whether the first reference signal reception quality meets the first range.

Further, after obtaining the second signal value of the target cell, the second signal value is compared with the second range to determine whether the second signal value exceeds the second range. Understandably, when the When the second signal value is greater than the maximum value of the second range, it may be determined that the second signal value exceeds the second range, and when the second signal value is less than the minimum value of the second range, it may be It is determined that the second signal value exceeds the second range, for example, the second range is (-5, 5), and when the second signal value is -6, it can be determined that the second signal value exceeds the second range In the second range, when the second signal value is 6, it can be determined that the second signal value exceeds the second range.

As a first way, when the second signal value includes a second received signal strength indicator, the second received signal strength indicator is compared with a second range to determine whether the second received signal strength indicator exceeds the second range. As a second way, when the second signal value includes a second signal-to-noise-interference power ratio, the second signal-to-noise-interference power ratio is compared with the second range to determine whether the second signal-to-noise-interference power ratio is Beyond the second range. As a third way, when the second signal value includes the second reference signal reception quality, the second reference signal reception quality is compared with the second range to determine whether the second reference signal reception quality exceeds the second range.

Step S104: When the first signal value satisfies the first range and the second signal value exceeds the second range, it is determined that the target cell is interfered.

In this embodiment, when the judgment result indicates that the first signal value satisfies the first range and the second signal value exceeds the second range, it may be considered that the first signal value is normal during the first time period of the target cell Fluctuations in the first range of, the fluctuation of the second signal value in the second time period exceeds the abnormal second range, which represents the interference received by the target cell.

Specifically, if the first signal value is the first received signal strength indicator, the second signal value is the second received signal strength indicator, when the first received signal strength indicator satisfies the first range, and the second received signal strength indicator When it is greater than the maximum in the second range, it indicates that the received signal strength fluctuates normally when the target cell is not interfered, and when the interference is received, the received signal strength indication of the target cell increases significantly, and it can be determined that the target cell is interfered with .

If the first signal value is the first signal-to-noise interference power ratio and the second signal value is the second signal-to-noise interference power ratio, when the first signal-to-noise interference power ratio satisfies the first range, and the second signal-to-noise interference power When the ratio is less than the minimum value in the second range, it indicates that the signal-to-noise-interference power ratio fluctuates normally when the target cell is not interfered with, and the signal-to-noise-to-interference power ratio of the target cell decreases significantly when it is interfered. The target cell is interfered.

If the first signal value is the first reference signal reception quality and the second signal value is the second reference signal reception quality, when the first reference signal reception quality meets the first range and the second reference signal reception quality is less than the second The minimum value of the range indicates that the reception quality of the reference signal fluctuates normally when the target cell is not interfered, and when the interference is received, the reception quality of the reference signal of the target cell significantly decreases, and it can be determined that the target cell is interfered.

Of course, in this embodiment, the received signal strength indication, the signal-to-noise-interference power ratio, and the reference signal reception quality can also be judged at the same time, and details are not described herein again.

Further, in this embodiment, when it is determined that the target cell is interfered, the mobile terminal can be controlled to access the 4G network and the 2G network and the 3G network are prohibited, enter the VOLTE mode, or control the mobile terminal to log off the network to enter the flight mode to avoid movement The terminal accesses the 2G pseudo base station to ensure the information security of the mobile terminal.

Please refer to FIG. 4, which is a schematic flowchart of a cell interference detection method according to another embodiment of the present application. The method is applied to the above mobile terminal, and the process shown in FIG. 4 will be described in detail below. The method may specifically include the following steps:

Step S201: Detect multiple first signal values of the target cell within a first time period, and the multiple first signal values are obtained by multiple detections of the target cell within the first time period.

In this embodiment, the number of the first signal value is multiple, and the multiple first signal values are obtained by detecting the target cell multiple times within a first time period. Specifically, the mobile terminal may detect multiple first signal values of the target cell multiple times in chronological order within the first time period. For example, the mobile terminal can detect the first signal value every 2 minutes, the first signal value every 5 minutes, etc. In addition, the number of the detected first signal value can be set manually by the user or automatically set by the mobile terminal , Not limited here.

Step S202: Detect a plurality of second signal values of the target cell in a second time period, and the plurality of second signal values are obtained by multiple detections of the target cell in the second time period.

Further, the number of the second signal value is multiple, and the multiple second signal values are obtained by detecting the target cell multiple times within a second time period. Specifically, the slave mobile terminal detects multiple second signal values of the target cell multiple times in chronological order within a second time period. For example, the mobile terminal can detect the second signal value every 10 seconds and the second signal value every 15 seconds. In addition, the number of detected second signal values can be set manually by the user or automatically set by the mobile terminal. No limitation here. As a way, the number of the first signal value and the number of the second signal value may be the same or different.

As a way, the plurality of first signal values are compared with the first range to determine whether the plurality of first signal values satisfy the first range, wherein, when the plurality of first signal values are in the first range When it is within, it is determined that the plurality of first signal values satisfy the first range, and when any first signal value of the plurality of first signal values is not within the first range, it is determined that the plurality of first signal values do not satisfy the first A range. In addition, each of the plurality of second signal values is compared with the second range to determine whether the plurality of second signal values exceed the second range, wherein, when the plurality of second signal values are not within the second range, it is determined The plurality of second signal values exceed the second range. When any second signal value in the plurality of second signal values is within the second range, it is determined that the plurality of second signal values do not exceed the second range.

Step S204: When the plurality of first signal values all satisfy the first range and the plurality of second signal values all exceed the second range, it is determined that the target cell is interfered.

In this embodiment, when the plurality of first signal values all satisfy the first range and the plurality of second signal values all exceed the second range, it is characterized that the detection of the first signal value and the detection of the second signal value are accurate, and it is determined that The target cell is interfered.

Step S205: The mobile terminal outputs prompt information.

Please refer to FIG. 5, which is a schematic flowchart of a cell interference detection method according to another embodiment of the present application. The method is applied to the above mobile terminal, and the process shown in FIG. 5 will be described in detail below. The method may specifically include the following steps:

Step S301: Detect the first signal value of the target cell within the first time period.

Step S302: Detect the second signal value of the target cell within a second time period, wherein the second time period is later than the first time period.

Step S303: determine whether the first signal value satisfies the first range, and determine whether the second signal value satisfies the second range, wherein the maximum value of the second range is greater than the maximum value of the first range, The minimum value of the second range is smaller than the minimum value of the first range.

For the specific description of steps S301-S303, please refer to steps S101-S103, which will not be repeated here.

Step S304: When the first signal value satisfies the first range and the second signal value exceeds the second range, demodulate the base station to be accessed in the target cell.

The target cell may correspond to multiple base stations to be accessed, and the signal strength of each base station is different. The mobile terminal will try to demodulate each base station to be accessed according to the order of the signal strength from high to low. Generally, in order to induce the mobile terminal to redirect to the 2G pseudo base station, the 4G pseudo base station usually has the strongest signal strength to induce the mobile terminal to use it as a base station to be accessed. Therefore, the mobile terminal may demodulate the pseudo base station.

Step S305: When demodulation fails, it is determined that the target cell is interfered.

When the demodulation of the access base station fails, it can be determined that the target cell is interfered.

Step S306: Obtain other cells adjacent to the target cell.

Step S307: Try to access the target base station corresponding to the other cell.

In this embodiment, after it is determined that the target cell is interfered, other cells adjacent to the target cell may be detected and acquired, in order to try to achieve the access of the mobile terminal to the network by accessing the target base station corresponding to the other cell .

Step S308: Determine whether the other cell is interfered.

Further, whether the other cell is interfered is detected and judged. The specific judgment method is similar to the judgment method of the target cell whether it is interfered, which will not be repeated here.

Step S309: When the other cell is interfered, control the mobile terminal to log out of the network and enter the flight mode.

If the judgment result indicates that the other cell is also interfered, for example, the other cell cannot use the 4G network, the cell covering the area where the mobile terminal is located is interfered. Therefore, the area where the mobile terminal is located is likely to have a pseudo base station. Therefore, in order to improve the information security of the mobile terminal, the mobile terminal can be controlled to log out of the network and enter the flight mode.

A cell interference detection method provided by another embodiment of the present application detects a first signal value of a target cell within a first time period, detects a second signal value of a target cell within a second time period, and determines whether the first signal value Satisfy the first range, and determine whether the second signal value meets the second range, wherein the maximum value of the second range is greater than the maximum value of the first range, the minimum value of the second range is less than the minimum value of the first range, when the first When a signal value satisfies the first range and the second signal value exceeds the second range, the base station to be accessed in the target cell is demodulated. When demodulation fails, it is determined that the target cell is interfered, and the target cell is acquired. Other neighboring cells try to access the target base station corresponding to the other cell to determine whether the other cell is interfered. When the other cell is interfered, the mobile terminal is controlled to log out of the network and enter the flight mode. Compared with the cell interference detection method shown in FIG. 3, when demodulation of the base station to be accessed in the target cell fails, this embodiment determines that the target cell is interfered, and then controls the mobile terminal when it is determined that the neighboring cell is interfered. Log off the network and enter the flight mode to improve the information security of mobile terminals.

Please refer to FIG. 6, which is a schematic flowchart of a cell interference detection method according to another embodiment of the present application. The method is applied to the above mobile terminal, and the process shown in FIG. 6 will be described in detail below. The method may specifically include the following steps:

Step S403: determine whether the first signal value satisfies the first range, and determine whether the second signal value satisfies the second range, wherein the maximum value of the second range is greater than the maximum value of the first range, The minimum value of the second range is smaller than the minimum value of the first range.

Step S404: When the first signal value satisfies the first range and the second signal value exceeds the second range, it is determined that the target cell is interfered.

For the specific description of steps S401-S404, please refer to steps S101-S104, which will not be repeated here.

Step S405: Obtain the current time.

Among them, the current time can be obtained by the clock provided by the mobile terminal.

Step S406: When the current time is within the third time period, control the mobile terminal to access the 4G network and prohibit the 2G network and the 3G network to enter the VOLTE mode.

Further, because the pseudo base stations used by most illegal elements are 2G networks and 3G networks, and 4G networks have only a few pseudo base stations. For example, the pseudo base stations used in 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 damage to mobile terminal users. Therefore, as a way, mobile terminals are prohibited from accessing 2G networks and 3G networks and setting mobile terminals to connect 4G networks to VOLTE The mode, in which VOLTE is Voice Over LTE, is a voice service based on IMS.

When the first duration is greater than the first duration threshold, 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 release the VOLTE mode to make the mobile The terminal can be used normally.

Step S410: When the current time is within a fourth time period, control the mobile terminal to log out of the network to enter the flight mode, wherein the third time period and the fourth time period are different.

Specifically, since the target cell where the mobile terminal is located may have a pseudo base station, and the pseudo base station generally attacks the mobile terminal through a 2G network or a 3G network, therefore, the mobile terminal reappears at any time during the process of using the network in the target cell The possibility of being attacked by a pseudo base station. 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 out of the network to enter the flight mode, thereby preventing the pseudo base station from attacking the mobile terminal through the 2G network or the 3G network, and improving the mobile terminal’s Information security. The fourth time period may be a time period during which the user does not need to use the mobile terminal. For example, the fourth time period may include 11 pm to 7 am, which is not limited herein.

Step S411: Detecting the second duration for the mobile terminal to enter the flight mode.

In this embodiment, after the mobile terminal is controlled to enter the flight mode, the second time duration for the mobile terminal to enter the flight mode is monitored and recorded. The monitoring methods may include real-time monitoring, interval monitoring at predetermined intervals, or according to the user’s own The set time interval monitoring, optional, in order to improve the accuracy of the monitoring time, you can use real-time monitoring.

Step S412: Determine whether the second duration is greater than a second duration threshold.

As a way, the mobile terminal sets a second duration threshold for judging the duration of the mobile terminal entering the flight mode. Understandably, the second duration threshold may be stored locally by the mobile terminal in advance, or may be Set again during judgment. In addition, the second duration threshold 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 the server connected to the mobile terminal and sent to the mobile terminal. Be limited. Further, after acquiring the second duration of the mobile terminal entering the flight mode, the second duration is compared with a second duration threshold to determine whether the second duration is greater than the second duration threshold.

Step S413: When the second duration is greater than the second duration threshold, control the mobile terminal to release the flight mode and access the network.

Understandably, when the second duration is greater than the second duration threshold, 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 be normal Access the network to ensure the normal use of mobile terminals.
