However, in one area, there are also cells established by other base stations, so that after a communication cell is established, the backpack base station also needs to find out possible co-channel interference signals in the same area in time during normal operation, so as to avoid affecting normal communication.

The base station establishes communication connection between the terminal equipment used by the user and the internet by establishing a cellular cell, so that the terminal equipment can send messages to each other to complete functions of communication, internet surfing and the like. The terminal equipment can normally communicate and surf the internet only within the coverage range of the cellular cell, so that the existence of the cellular cell is directly related to whether the local user can contact with the outside or not.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, when a place falls into a geological disaster such as house collapse and landslide, the operator base station 100 is damaged and cannot provide communication service for a while, and the collapsed building forms a ruin 200, people who cannot escape in time are trapped in the ruin 200 and cannot move freely, and thus cannot leave the predicament. In this case, the trapped person 300 needs to send information for help, such as detailed trapped location and rescue demand, to the outside through the terminal 400 by using a network, so that the rescuer can perform timely and accurate rescue. However, at this time, the function of the operator base station 100 is destroyed, and the terminal 400 at that location cannot send information to the outside until the repair is made. Therefore, a cell can be established by the backpack base station 1 to provide a communication service to the terminal 400 of the person in the area.

In addition to the backpack base station, there may be other operator base stations or other commercial base stations, and each base station may establish a cell according to a certain frequency point to provide a communication service for the terminal 400 of the user. The frequency point used by each base station to establish the cell cannot be the same as the frequency points of other cells existing in the area, otherwise, signals among a plurality of cells interfere with each other, and normal communication is influenced.

The backpack base station 1 cannot know the frequency point information used by other operator base stations or other commercial base stations existing in the place. Therefore, the backpack base station 1 not only needs to avoid the conflict with the signals of the cells currently existing in the area when the cells are established, but also needs to find and avoid the conflict with the frequency points used by some newly established cells or re-established cells in time.

In order to solve the above problem, an embodiment of the present application provides a method for automatically detecting interference, which is applied to a backpack base station, and after a cell is established in the area, the backpack base station 1 can timely detect whether there is co-channel interference in the current area when the cell normally works, so as to ensure that the cell can always provide normal communication service, so that the terminal 400 can communicate with the outside at any time, send out distress information, and help the trapped person 300 to be rescued in time.

Fig. 2 is a flowchart illustrating a method for automatically detecting interference according to an embodiment of the present application. As shown in fig. 2, the method for automatically detecting interference provided in the embodiment of the present application may be applied to a backpack base station, and specifically includes:

s101, receiving or transmitting a first radio frequency signal in a target area based on the working frequency point.

The frequency band is generally a frequency resource used by a communication system or an operator, specifically, a frequency point may be determined according to a frequency band for communication distributed to each operator, and the backpack base station receives a radio frequency signal of a target area based on the frequency point. For example, the frequency band is 800MHz-820MHz, any frequency point in the frequency band is a frequency point, for example, the frequency point is a frequency point of 810MHz, and the backpack base station can receive a radio frequency signal with a frequency of 810MHz based on the frequency point of 810 MHz.

Alternatively, the frequency point may be a number of a fixed frequency. For example, in a Global System for Mobile Communications (GSM) 900 System, 890MHz to 915MHz of an uplink are divided into 125 radio frequencies at 200KHz intervals, such as 890MHz, 890.2MHz, 890.4MHz, 8230, 915MHz, and each frequency is numbered as 1, 2, 3, 8230, 125, and 1 to 125, i.e., frequency points, and each frequency point corresponds to one frequency. The backpack base station can receive radio frequency signals with the frequency of 890.4MHz based on the frequency point 3.

Specifically, the backpack base station provides communication service for the terminal in the target area by receiving or transmitting the first radio frequency signal. The target area is a signal coverage area of the backpack base station, the working frequency point is a frequency point used by the backpack base station for building a cell, and the backpack base station receives and transmits a first radio frequency signal based on the working frequency point to provide normal communication service.

And S102, entering a detection mode when a detection trigger condition is met.

It will be appreciated that in some cases there may be other commercial base stations for the target area to establish cells, or the operator base station may repair and re-operate after it has been damaged. If the frequency point of the cell established by the commercial base station is consistent with the working frequency point used by the cell established by the backpack base station, or the frequency point of the operator base station is consistent with the working frequency point used by the cell established by the backpack base station, the cell established by the backpack base station can be interfered by the commercial base station and/or the cell of the operator base station. Therefore, in order to find out the co-channel interference signal in time, a trigger condition is preset, so that when the trigger condition is met, the backpack base station is triggered to enter an interference detection mode. Optionally, the triggering condition may be to determine whether the current working cycle of the backpack base station is in a preset detection cycle, or the triggering condition may be to determine whether the number of terminals with abnormal connection state with the backpack base station is greater than or equal to a first threshold.

Optionally, when the triggering condition is to determine whether the current working period of the backpack base station is in a preset detection period, the current working period may be obtained, and when the current working period is determined to be in the preset detection period, the backpack base station enters a detection mode.

Wherein, the current working cycle may include a transceiving signal cycle and an idle cycle. The transceiving signal period refers to a time period for receiving or transmitting the first radio frequency signal after the backpack base station establishes the cell. The idle period refers to a time period between two adjacent transceiving signal periods.

In this embodiment, since the backpack base station is configured to enter the interference detection mode when the current working period is in the idle period, the preset detection period may be set to be N idle periods apart; wherein N is a positive integer.

Illustratively, when N is 2, the preset detection period is 2 idle periods apart. If the current working period acquired by the backpack base station is an idle period, and the idle period is the 2 nd idle period after the backpack base station enters the detection mode last time, it is indicated that the backpack base station is not in the preset detection period at present, and then the backpack base station does not enter the detection mode. And assuming that the current working period acquired by the backpack base station is an idle period, and the idle period is the 3 rd idle period after the backpack base station enters the detection mode last time, which indicates that the backpack base station is in the preset detection period at present, the backpack base station enters the detection mode.

Whether the backpack base station enters the detection mode or not is determined by whether the working period meets the preset detection period or not, whether co-channel interference signals exist in a target area or not can be periodically detected by the backpack base station, the occurrence frequency of the backpack base station automatically entering the detection mode can be adjusted according to needs through the setting of the preset detection period, for example, when the number of the base stations visible in the target area is large, the possibility of co-channel interference is considered to be high, the preset detection period can be set to be a short period at the moment, the frequency of detecting interference is improved, and the interference signals can be found in time. Correspondingly, if the number of the base stations visible in the target area is small, the possibility of co-channel interference is considered to be low, and at this time, the preset detection period can be set to be a long period, so that the power consumption of the backpack base station and the occupancy rate of hardware resources are reduced.

Optionally, when the triggering condition is that whether the number of terminals in abnormal connection state with the backpack base station is greater than or equal to a first threshold is judged, the number of abnormal terminals in abnormal connection state with the backpack base station in the target area may be obtained, and when the number of abnormal terminals is judged to be greater than or equal to the first threshold, the detection mode is entered.

Specifically, the backpack base station and the terminals are always in a communication connection state, when the backpack base station finds that communication between the backpack base station and the connected terminals is abnormal, the number of abnormal terminals can be recorded, if the number of the abnormal terminals is larger than or equal to a first threshold value, the probability that the terminals are in fault is low, the probability that the cell currently established by the backpack base station is interfered is high, and the backpack base station can enter a detection mode to judge whether an interference signal exists.

For example, the first threshold may be 25. When the terminals and the backpack base station are in abnormal communication, the backpack base station updates the number of the abnormal terminals, 4 abnormal terminals appear after the backpack base station works for two minutes, after the backpack base station continues to work for a period of time, 23 abnormal terminals and the backpack base station are in abnormal communication, at the moment, the backpack base station records that the number of the abnormal terminals is 27, the abnormal terminals are more than a first threshold value, and the possibility that the 27 abnormal terminals are in failure is low, so that the backpack base station enters a detection mode and judges whether the abnormal communication with the terminals is caused because interference signals with the same frequency as the interference signals exist in a target area.

Through monitoring the abnormal terminal which is connected with the backpack base station in an abnormal state, the detection requirement can be timely found, and whether the same frequency interference exists in the cell or not is judged by entering a detection mode in time.

Optionally, after the backpack base station establishes the cell based on the working frequency point, the state parameter is modified to a first preset value, and when the state parameter is the first preset value, it indicates that the backpack base station enters a triggerable state of the detection mode. For example, the first preset value is 0, the backpack base station modifies the state parameter to 0 after establishing the cell, and the state parameter is consistent with the first preset value, which indicates that the backpack base station enters a state that can trigger the detection mode at any time. In the above case, the backpack base station may enter the detection mode only when the detection trigger condition is satisfied.

In the technical scheme of the embodiment of the application, the backpack base station can enter the detection mode as required at any time, further, in consideration of saving communication resources, a detection trigger condition can be set, when the detection trigger condition is met, the probability that interference exists at present is high, and whether the interference exists needs to enter the detection mode to detect so as to timely respond.

After the backpack base station enters the detection mode, S103 is executed:

s103, detecting whether an interference signal exists in the target area in the protection time slot of the first radio frequency signal receiving and transmitting.

Specifically, the communication mode that the district was established to the knapsack base station is the time division duplex mode, under this mode, the knapsack base station uses same work frequency point receiving and sending signal, on, the downlink uses different protection time slot to communicate, consequently can be at district receiving and sending signal's clearance, based on the regional radio frequency signal of the available frequency point receipt target of target, also, under the time division duplex mode, the knapsack base station can be as required at any time, whether there is interference signal in the clearance detection target area of receiving and sending signal, do not influence normal communication work.

It can be understood that, the cell established by the backpack base station provides communication service by sending and receiving signals based on the working frequency point, and the backpack base station detects whether there is an interference signal in the target area, and needs to receive the radio frequency signal in the target area based on the working frequency point. Therefore, in the detection mode, when the backpack base station receives a signal, if the backpack base station simultaneously receives and transmits the first radio frequency signal, the backpack base station cannot avoid the signal transmitted by the cell established by the backpack base station, so that it cannot be determined whether the radio frequency signal received during detection is a signal transmitted by the backpack base station in normal operation or a signal transmitted by a cell of another base station, and it cannot be determined whether a cell with co-frequency interference exists in the target area. Therefore, the detection mode is entered in the cell transmitting and receiving gap, and the condition of misjudgment caused by receiving the own cell radio frequency signal can be directly avoided.

Specifically, fig. 3 is another schematic flow chart of the method for automatically detecting interference according to the embodiment of the present application. As shown in fig. 3, in this step, the detecting whether there is an interference signal in the target area by the backpack base station may include:

s201, receiving a second radio frequency signal in the target area based on the working frequency point.

The backpack base station can accurately receive the radio frequency signals corresponding to the frequency points in the target area based on the frequency points so as to scan the radio frequency signals existing in the target area. When the backpack base station does not transmit the first radio frequency signal, it may be said that an interference signal colliding with a cell established by the backpack base station exists in the target area if the backpack base station receives the second radio frequency signal having a frequency identical to that of the first radio frequency signal. Therefore, the radio frequency signals in the target area can be directly received based on the working frequency points, and the purpose is clear, quick and effective.

S202, acquiring the signal power of the second radio frequency signal.

Specifically, the backpack base station calculates the signal power of the second radio frequency signal according to the received second radio frequency signal. The higher the signal power, the stronger the signal strength of the second rf signal, and the more likely it is to be an rf signal for communication. If the signal power is small, it may be a cell edge signal provided by a base station in a distant area, or a channel noise signal of a receiver, and in this case, the received second rf signal is not necessarily an rf signal used by another cell for communication.

S203, judging whether the second radio frequency signal is an interference signal or not based on the signal power.

The cellular cell established by the base station of the operator sends out a signal with a certain frequency, and the energy of the signal is gradually lost in the transmission process. If the cell is far from the target area, the signal power of the frequency provided by the cell in the target area for communication is low, and an effective communication function cannot be provided for the user in the target area. Therefore, whether the radio frequency signal corresponding to the signal power has an effective communication function in the target area can be seen through the signal power, so that whether the frequency point corresponding to the radio frequency signal can provide the corresponding communication function for the target area is judged, and if the frequency point can provide the communication function for the target area, the frequency point is occupied by a certain base station, and the backpack base station cannot establish a cell in the target area by using the frequency point.

Optionally, when determining whether the second radio frequency signal is an interference signal, S203 may include:

s2031, determining the effective value of the second radio frequency signal based on the signal power.

In this step, whether the second radio frequency signal is a valid signal may be determined according to the signal power of the second radio frequency signal, and then whether the second radio frequency signal is an interference signal may be determined. Specifically, the probability of the second radio frequency signal being unoccupied is represented by a valid value, and the larger the valid value, the smaller the signal strength of the second radio frequency signal is, and the less likely it is to be an interference signal.

Optionally, when the signal power is determined to be less than or equal to the valid signal threshold, the valid value of the second radio frequency signal is updated according to a preset rule. Or when the signal power is judged to be larger than the effective signal threshold value and the difference value between the signal power and the effective signal threshold value is smaller than or equal to the signal fluctuation threshold value, updating the effective value of the second radio frequency signal according to a preset rule.

Alternatively, the valid signal threshold may be a noise floor of a receiver of the backpack base station, or a minimum power obtained from a radio frequency signal when the cell is transmitting or receiving. The units of the effective signal threshold, the background noise and the minimum power are all decibel milliwatts (dBm). It can be understood that when the receiver of the backpack base station is powered on to work, a fixed background noise exists, and the fluctuation is extremely small, so that whether the second radio-frequency signal received by the receiver is only the working background noise of the receiver can be judged according to the background noise of the receiver or a value close to the background noise. If yes, the currently received second radio frequency signal is only the working background noise, and no effective radio frequency signal is actually received, so that no interference signal which conflicts with the cell of the backpack base station exists.

Illustratively, the valid signal threshold may be 30dBm, and if the signal power of the second radio frequency signal is 10dBm, the signal power of the second radio frequency signal is smaller than the valid signal threshold, and the valid value is updated according to a preset rule. And if the signal power of the second radio frequency signal is 40dBm, judging again according to the signal fluctuation threshold value. For example, the signal fluctuation threshold is 5dBm, the difference between the signal power of the second radio frequency signal and the effective signal threshold is 10dBm, which does not satisfy the requirement of being less than or equal to the signal fluctuation threshold, so the effective value is not updated. And if the signal power of the second radio frequency signal is 33dBm, the requirement that the signal power is less than or equal to the signal fluctuation threshold value is met, and the effective value is updated according to a preset rule.

Alternatively, the initial value of the valid value may be 0, or any other value applicable to the preset rule. The preset rule may be to add one to the valid value, and the valid value of the second rf signal may be simply and effectively counted by adding one or no operation to the valid value. For example, each interference detection process includes 5 scans of the working frequency point, the radio frequency signal obtained by each scan is subjected to effective value counting once, when the initial effective value is 0 and the preset rule is that the effective value is added to one, the effective value can be added when the radio frequency signal obtained by each scan is an effective signal, and if the radio frequency signal obtained by 4 scans in 5 scans is an effective signal, the finally obtained effective value of the second radio frequency signal received based on the working frequency point is 4.

For example, the predetermined rule may also be determined based on a difference between the signal power of the second rf signal and the valid signal threshold, for example, when the difference is smaller, the valid value is higher and may be 0.9, and when the difference is larger, the valid value is lower and may be 0.08, for example. Effective values are determined through the difference value of the signal power and the effective signal threshold value, weight distribution can be carried out on the signal power with different sizes, and the effectiveness of the second radio frequency signal is expressed through the accurate effective values.

After determining the valid value of the second radio frequency signal, S2032 is performed:

s2032, under the condition that the effective value is judged to be less than or equal to the second threshold value, the second radio frequency signal is determined to be an interference signal.

As can be seen from the foregoing, the valid value indicates the possibility that the second rf signal is unoccupied, so the smaller the valid value is, the more likely the second rf signal is an interference signal. When the valid value is less than or equal to the second threshold, the second radio frequency signal may be determined to be an interference signal.

Optionally, in the detection mode, the backpack base station may receive the second radio frequency signal for multiple times based on the working frequency point, and cumulatively update the effective value for multiple times, so that the possibility of the second radio frequency signal being unoccupied can be determined through multiple judgments, and the misjudgment probability is reduced.

It can be understood that, under the condition that the possibility that the second radio frequency signal is unoccupied is determined for multiple times, when the setting condition is satisfied, it is described that the number of scanning times and/or the scanning time for the working frequency point meet the requirement, as can be known from S2031 described above, it is necessary to determine whether to update the effective value every time of scanning in the detection mode, and therefore, after multiple times of scanning for the working frequency point are finished, the effective value may be an initial value, or a value different from the initial value after at least one time of updating.

Illustratively, if the initial value of the effective value is 0, updating the effective value every time is to add one to the effective value, assuming that the second threshold is 3, the number of times of scanning the first frequency point by the backpack base station is 5, where 4 times of scanning satisfy the requirement for updating the effective value, the finally obtained effective value is 4, and at this time, the effective value is greater than the second threshold, so that it can be determined that the second radio frequency signal is an interference signal.

The misjudgment probability is reduced by judging whether the radio frequency signal is an effective signal, the working frequency points are scanned for multiple times, and effective values scanned at each time are accumulated, so that errors possibly existing in single scanning can be eliminated, and the judgment on the effective signal is more accurate.

According to the method for automatically detecting the interference, the detection trigger condition is set, the possibility that the interference exists at present can be judged, the detection mode is entered when the possibility is high, communication resources occupied by always triggering the detection mode are avoided, and after the backpack base station enters the detection mode, whether the interference signal exists in a target area or not is detected only in the receiving and sending protection time slot of the first radio frequency signal, so that the same-frequency interference signal which possibly exists in the same area can be timely found while normal communication service is provided for the terminal without being influenced.

Further, in view of the fact that the backpack base station provides better communication service quality when detecting that there is an interference signal in the target area, in this embodiment, after S103, the method for automatically detecting interference may further include:

and S104, if the backpack base station detects that the interference signal exists in the target area, closing the current cell, and reselecting the frequency point to establish the cell.

It should be understood that when the frequency point corresponding to the second radio frequency signal scanned by the backpack base station is a working frequency point, it indicates that the cell established by the backpack base station and the cells established by other base stations use the same frequency to communicate in the target area, so that the communication services in the target area conflict. Therefore, when the backpack base station monitors that there is a collision/interference signal in the target area, the backpack base station may reselect another available frequency point to establish a cell, so as to avoid collision with other cells in the target area.

Therefore, in an implementation manner, before the backpack base station establishes the cell, or before the backpack base station reselects the frequency point to establish the cell, the present embodiment may further scan the target area by using the interference detection function of the backpack base station, determine the frequency point used by the cell currently existing in the target area, and exclude the used frequency point from the preset frequency points, so as to select any frequency point from the unused frequency points as a working frequency point, so as to ensure that the initial cell established by the backpack base station or the cell reestablished by the backpack base station does not conflict with other cells currently existing in the target area.

Optionally, when determining a frequency point that is not used by a currently existing cell in the target area, the frequency point may be recorded in the available frequency point list, and after selecting any frequency point from the available frequency point list as a working frequency point, the working frequency point may be deleted from the available frequency point list. In this case, when the backpack base station detects an interference signal, any frequency point can be selected from the available frequency point list to reconstruct the cell after the cell is closed, so that the cell can be established more conveniently and accurately.

Optionally, the frequency points in the preset frequency point list may be marked by setting a marking bit, and are distinguished into an available frequency point and an occupied frequency point. After the working frequency points are selected to establish the cell, the frequency points are marked as occupied frequency points, the marks of the available frequency points are removed from the marks corresponding to the working frequency points, when the frequency points are convenient to manage, the frequency points can be directly selected from the available frequency point list when the cell is reestablished in the backpack base station, the working frequency points can be selected again without worrying, the frequency points can be managed by marking the frequency point types, and the corresponding frequency points can be conveniently obtained as required.

Optionally, the process of scanning the target area by using the interference detection function of the backpack base station to determine the frequency point that is not used by the cell currently existing in the target area may include:

s301, receiving a third radio frequency signal of the target area based on the frequency point to be scanned, wherein the frequency point to be scanned is a first frequency point in the preset frequency points.

The backpack base station can stop scanning after determining one or a plurality of available frequency points, and can also scan all the frequency points in the preset frequency points to determine all the available frequency points in the preset frequency points.

Optionally, fig. 4 is a schematic flowchart of a method for frequency point scanning according to an embodiment of the present application. As shown in fig. 4, when the backpack base station needs to scan all frequency points in the preset frequency points, step S301 receives a third radio frequency signal based on the frequency point to be scanned, which may further include:

s3011, judging whether all frequency points in the preset frequency points are scanned completely.

Alternatively, the preset frequency points may be sequentially scanned. For example, multiple frequency points in the preset frequency points may correspond to the sequence numbers one to one, for example, frequency point 1 corresponds to sequence number 0, frequency point 2 corresponds to sequence number 1, and so on, frequency point n corresponds to sequence number n-1. And the backpack base station scans from the frequency point 1 according to the sequence number, and determines that all frequency points are scanned completely after the backpack base station receives a third radio frequency signal based on the frequency point n or scans the sequence number n-1. Or, the backpack base station judges whether the scanning is finished according to the times, determines to finish the scanning after the scanning is carried out for n times, and indicates to scan part of the preset frequency points when the scanning times are less than n times. For example, when 150 preset frequency points exist, 100 cells which can exist in a target area are expected to exist, at least g available frequency points are obtained through presetting, 100+ g frequency points can be scanned, 100 occupied frequency points can be eliminated after scanning is completed, and g available frequency points are obtained and used for building cells.

Alternatively, the preset frequency points may be scanned non-sequentially. For example, the backpack base station randomly selects any one frequency point from the preset frequency points as a first frequency point, scans the first frequency point and marks the first frequency point as a scanned frequency point, or scans the first frequency point and deletes the first frequency point from a resource pool of the preset frequency points, and when the number of the remaining frequency points in the preset frequency points is k, the backpack base station determines that the scanning is completed. The resource pool may store the information of the preset frequency point in a table form, which is not limited in the present application. k is equal to n, the preset number and the number of the cells currently existing, and k is 0 to represent that all frequency points are scanned.

And S3012, if yes, determining that the backpack base station finishes scanning all frequency points of the preset frequency points, and executing the processing of the S101.

The purpose of the backpack base station scanning the preset frequency point is to obtain an available frequency point for the backpack base station to establish a cell. Therefore, when the backpack base station scans all the frequency points, the available frequency point list can be obtained, so that the frequency points for establishing the cell can be selected from the available frequency point list.

S3013, if not, the backpack base station does not complete the scanning of all the frequency points of the preset frequency points, and whether the scanning of the frequency points to be scanned meets the set conditions is judged.

For example, the setting condition may be a preset number of scanning times or a preset scanning time. For example, if the preset condition is that scanning is preset for 5 times, the frequency point to be scanned needs to be scanned for 5 times; or if the preset scanning time is 3 minutes, the frequency point to be scanned needs to be scanned for 3 minutes, and if each scanning is set for 30 seconds, the scanning can be performed for 6 times within 3 minutes. That is, the number of scanning times may be set directly, only the setting of the scanning time may be considered, and the number of scanning times may be set by the scanning time and the scanning interval so as to satisfy the requirements of both time and number of times.

And S3014, if yes, selecting a second frequency point from the preset frequency points as a frequency point to be scanned, and executing processing for receiving a third radio frequency signal of the target area based on the frequency point to be scanned.

Specifically, when the set condition is met, it is described that the scanning times and/or scanning time of the first frequency point meet the requirements, and the backpack base station finishes scanning the first frequency point, so that the scanning of the second frequency point can be started.

Optionally, a second frequency point adjacent to the first frequency point may be sequentially selected as a frequency point to be scanned, or any one frequency point may be randomly selected as a frequency point to be scanned in a resource pool in which the scanned frequency point is deleted.

And S3015, if not, continuing to execute the processing of receiving the third radio frequency signal of the target area based on the frequency point to be scanned in S301.

It can be understood that, the scanning of the frequency point to be scanned does not satisfy the setting condition, which indicates that the scanning of the frequency point is not finished, and therefore, the frequency point is continuously scanned until the number of scanning times and/or time satisfy the setting condition.

And S302, acquiring the signal power of the third radio frequency signal.

And S303, adding the frequency point to be scanned to the available frequency point list under the condition that the third radio frequency signal is determined to be the effective signal based on the signal power.

The effective signal is a radio frequency signal which is not occupied in a target area, so that a frequency point corresponding to the radio frequency signal can be used as a frequency point of a backpack base station for building a cell. For example, the third radio frequency signal is an effective signal, which means that the third radio frequency signal exists in the target area and the signal power of the third radio frequency signal is low, so that the terminal in the target area cannot establish a connection with an external network through the third radio frequency signal, and therefore the frequency point to be scanned corresponding to the third radio frequency signal is not used by the operator base station or other commercial base stations around the target area. The frequency points in the unused preset frequency points in the target area can be added to the available frequency point list so that the backpack base station can select the frequency points to establish a cell, and the cell is ensured not to generate interference or conflict with other stored cells in the target area.

Specifically, when determining whether the third radio frequency signal is a valid signal, the valid value of the third radio frequency signal may be determined first, and the third radio frequency signal may be determined to be a valid signal when determining that the valid value is greater than the second threshold. For determining the valid value, reference may be made to S2031, which is not described herein again.

And S304, establishing a cell based on the working frequency points in the available frequency point list. Wherein, the working frequency point is any frequency point in the available frequency point list.

As shown in fig. 1, after a backpack base station 1 establishes a cell at a certain location in ruins 200 based on a working frequency point, the backpack base station 1 may receive a radio frequency signal 500, such as a distress signal, sent by a terminal 400 of a trapped person 300 through the backpack base station 1, and may also send information to the terminal 400, thereby establishing communication between the outside and the terminal 400.

Optionally, any frequency point may be randomly selected from the available frequency point list as a working frequency point, or a frequency point with the minimum interference in the available frequency point list may be preferentially selected.

Through the steps, occupied frequency points and unoccupied frequency points can be accurately distinguished, and any frequency point is selected as a working frequency point from a finally obtained available frequency point list consisting of at least one unoccupied frequency point, so that conflict with other signals in a target area can be avoided.

It can be understood that, in the process of scanning the target area, only the receiving channel of the backpack base station is used, and the backpack base station mentioned in this embodiment includes, but is not limited to, 2G, 3G, 4G, 5G, and a wireless network standard that may be provided by a future operator.

The radio frequency signals in the target area are received for multiple times according to the single frequency point, and effective value judgment is carried out on the received radio frequency signals every time, so that whether the radio frequency signals are effective signals or not is judged, errors possibly existing in the process of receiving the signals are eliminated, the available frequency points in the preset frequency points are accurately determined, an accurate available frequency point list is obtained, the backpack base station can accurately establish a cell when using information of relevant frequency bands of the target area is not known, the cell does not conflict with signals of the existing cellular cell of the target area, and the using requirements of the terminal in the target area are met.
