Detailed Description

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not construed as indicating or implying relative importance.

At present, with the rapid development of electronic information technology, many electronic devices are equipped with positioning systems and communication systems. However, when the electronic device communicates through the communication system, it may interfere with the positioning system of the electronic device. How to reduce the interference caused by the communication system to the positioning system becomes a problem to be solved urgently.

Currently, a Positioning module of an electronic device generally includes a Global Navigation Satellite System (GNSS), wherein the GNSS is a generic name for a Global Positioning System (GPS), a compass, a Glonass (Glonass), a Galileo (Galileo), and other Satellite Navigation systems. Wherein, the general working frequency of the positioning module is about 1.2G-1.5 Ghz. The communication module of the electronic device may generally comprise a cellular communication module, wherein the cellular communication module may comprise a larger number of communication bands.

Further, since the global navigation satellite system GPS has been used most widely since it is deployed globally earlier, it is becoming a standard to configure the global navigation satellite system GPS on an electronic device. The sensitivity of the global navigation satellite system GPS is lower than-140 dBm, and the sensitivity of the cellular communication module in the communication module is about-110 dBm, namely the sensitivity of the global navigation satellite system GPS is relatively weak and much. Therefore, the global navigation satellite system GPS is also sensitive to interfering signals.

Further, the electronic devices support more frequency bands, for example, some mobile phones can support up to 30 frequency bands. The electronic devices are equipped with a large number of antennas, for example, some mobile phones are equipped with 10 antennas. Therefore, it is difficult to obtain a high isolation between the antennas in a small spatial range. The lower the isolation of the antennas is, the higher the signal strength of the transmission signal of one antenna which is injected into the other antenna is. The transmitted signal of the cellular communication module cannot completely eliminate the out-of-band signal, the main wave signal is increased, and the corresponding out-of-band signal is also increased; the decrease in the main wave signal, and the corresponding out-of-band signal, also decreases. For example, referring to fig. 1, fig. 1 shows a schematic diagram of frequency band interference. In fig. 1, the abscissa is frequency in Hz and the ordinate is power in dBm. The curve f1 is the transmission signal of the cellular communication module, wherein the central frequency band of the main signal of the curve f1 is 1880-1920MHz, the out-of-band signal is distributed around the frequency band of 1500MHz-2500MHz, and the out-of-band signal of the transmission signal of the cellular communication module is proportional to the intensity of the main signal. The curve f2 is a frequency band corresponding to the global navigation satellite system GPS, and the center frequency of the curve f2 is 1575.42Mhz, so that the interference of the out-of-band signal of the transmission signal of the cellular communication module may be caused, that is, the out-of-band Noise of the transmission signal of the cellular system at the center frequency of the global navigation satellite system GPS may raise the bottom Noise (Noise Floor) of the global navigation satellite system GPS, thereby reducing the sensitivity of the global navigation satellite system GPS. For example, when the strength of the transmitted signal of a cellular system is 20dBm, its out-of-band noise amplitude in the GPS band is about-30 dBm. When the strength of the transmitted signal of the cellular system is around 0dBm, the out-of-band noise of the GPS band is about-50 dBm. It can be seen that the lower the transmitted signal strength of the cellular system, the less its impact on the global navigation satellite system GPS sensitivity.

In order to reduce the interference of the transmission signal of the cellular system to the global navigation satellite system GPS, that is, the influence of sensitivity, a Surface Acoustic Wave filter (Surface Acoustic Wave filter) may be added to the cellular system, and the Surface Acoustic Wave filter may suppress an out-of-band signal of the transmission signal of the cellular system, so as to reduce the interference of the out-of-band signal to the global navigation satellite system GPS. It is also possible to control the global navigation satellite system GPS to be turned off when the cellular system transmits signals, thereby avoiding interference by the cellular system's transmitted signals.

Specifically, when the cellular system transmits a signal, the sensitivity corresponding to the global navigation satellite system GPS can be respectively obtained without adopting any method, adding a sound table filter to the cellular system, and controlling the global navigation satellite system GPS to be turned off, and table 1 is prepared for reference.

TABLE 1

Wherein 10 time slots may be included in a data frame duration and the slot duty cycle is used to characterize the percentage of time slots that control global navigation satellite system GPS turn-off, e.g., 1/10 indicates that global navigation satellite system GPS is turned off for one slot duration during the data frame duration and not turned off for the other 9 time slots within the data frame duration. As can be seen from table 1 above, when the acoustic surface filter is added to the cellular system and the GPS is controlled to be turned off when the cellular system transmits signals, the influence of the cellular system transmission signals on the GPS sensitivity can be effectively reduced. As can also be seen from table 1 above, the more time slots the cellular system takes to transmit signals during a cycle of a data frame, the more the global navigation satellite system GPS sensitivity decreases.

However, the inventor of the present invention found in research that, in the above prior art, adding the acoustic surface filter to the cellular system would increase the cost, and the acoustic surface filter would increase the in-band loss of the transmission signal of the cellular system, so that the overall power consumption of the cellular system is increased. For the method of controlling the global navigation satellite system GPS to turn off when the cellular system transmits signals, please refer to table 1, although turning off the global navigation satellite system GPS at intervals can avoid the influence of the cellular system transmitted signals on the sensitivity of the global navigation satellite system GPS, the more time slots occupied by turning off the global navigation satellite system GPS at intervals, the more the sensitivity of the global navigation satellite system GPS is reduced.

Therefore, in order to overcome the above-mentioned drawbacks, the present application provides a control method, an apparatus, an electronic device, and a storage medium.

Referring to fig. 2, fig. 2 shows an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 includes a main control module 110, a communication module 120, and a positioning module 130. The main control module 110 is connected to the positioning module 130 and the communication module 120, respectively.

For some embodiments, the main control module 110 may be configured to obtain signal transmission power when the communication module 120 transmits a signal, and then control the positioning module 130 to operate in different operation modes based on the signal transmission power, so as to reduce interference to the positioning module 130 when the communication module 120 transmits a signal and improve positioning sensitivity of the positioning module 130.

The main control module 110 may be a processor, and the processor may include one or more processing cores. The main control module 110 connects various parts within the entire electronic device 100 using various interfaces and lines. Alternatively, the main control module 110 may be implemented in at least one hardware form of a Micro Control Unit (MCU), a Digital Signal Processing (DSP), a Field-Programmable Gate Array (FPGA), and a Programmable Logic Array (PLA).

The communication module 120 may be used to implement the function of the electronic device 100 to transmit information. For example, the electronic device 100 needs to upload data to a server, and the data can be transmitted to the server through the communication module 120. The communication module 120 may be a cellular communication module, wherein the cellular communication module may include more communication frequency bands, such as a B1 (1920-.

The positioning module 130 may be used to implement the positioning function of the electronic device 100. For example, the specific location of the electronic device 100 may be determined by the location module 130. The positioning module 130 may include at least one of a global positioning module GPS, beidou, Glonass, and Galileo.

It should be noted that the electronic device 100 may be a smart phone, a notebook computer, a smart tablet, or the like.

Referring to fig. 3, fig. 3 is a diagram illustrating an application scenario of a control method according to an embodiment of the present application, that is, a control scenario 200, where the control scenario 200 includes: a user 210 and an electronic device 100. As shown in fig. 3, the electronic device 100 is a smartphone, and the user 210 is using a weather application running in the electronic device 100. The weather application running in the electronic device 100 may then call the location module 130. At this time, the main control module 110 in the electronic device 100 may obtain the signal transmission power when the communication module 120 transmits the signal, and then control the positioning module 130 to operate in different operating modes based on the signal transmission power, so that interference to the positioning module 130 when the communication module 120 transmits the signal may be reduced, and the positioning sensitivity of the positioning module 130 may be improved.

Further, a specific method for the main control module 110 to control the positioning module 130 to operate in different operation modes can be seen in the following embodiments.

Referring to fig. 4, fig. 4 illustrates a control method provided in an embodiment of the present application, where the method may be applied to the main control module 110 in the electronic device 100 in the foregoing embodiment, and the electronic device further includes a communication module 120 and a positioning module 130. The main control module 110 is connected to the positioning module 130 and the communication module 120, respectively. Specifically, the method includes steps S110 to S130.

Step S110: and acquiring the signal transmitting power of the communication module.

For some embodiments, the communication module may cause interference to the positioning module when transmitting signals, which may reduce the positioning sensitivity of the positioning module. When the signal transmitting power of the communication module is higher, the interference caused to the positioning module is also higher, and when the signal transmitting power of the communication module is lower, the interference caused to the positioning module is lower. Therefore, when the communication module transmits signals, the positioning module is controlled not to work, so that the interference of the communication module to the positioning module when the communication module transmits signals is reduced, and the positioning sensitivity of the positioning module is improved. However, the control of the positioning module to be inoperative also reduces the positioning sensitivity of the positioning module, wherein the control of the positioning module to be inoperative reduces the positioning sensitivity to a lesser extent than the positioning sensitivity of the positioning module when the signal of the communication module is at a greater transmission power, and to a greater extent than the positioning sensitivity of the positioning module when the signal of the communication module is at a lesser transmission power. Therefore, only when the signal transmission power of the communication module is larger, the positioning module can be controlled not to operate because the degree of the positioning sensitivity reduction caused by the positioning module not operating at the time is smaller than the degree of the positioning sensitivity reduction caused by the signal transmission power of the communication module being larger. When the signal transmission power of the communication module is smaller, the positioning module can be controlled to continuously work because the positioning module is controlled not to work at the moment, so that the degree of the reduction of the positioning sensitivity of the positioning module is greater than the degree of the reduction of the positioning sensitivity of the positioning module when the signal of the communication module is in the smaller transmission power. The lower the positioning sensitivity of the positioning module is, the higher the signal power required by the positioning module to transmit the same data is, i.e. the lower the efficiency is.

Further, the communication module may transmit a signal, where the signal may have different communication frequency bands and powers, and the power of the signal is the signal transmission power of the communication module. As can be seen from the foregoing, the communication module may include a plurality of communication bands, and each communication band may transmit signals at different transmission powers. For example, communication band a may transmit signals at power a1, and communication band a may also transmit signals at power a 2; the communication band B may transmit signals at power B1 and the communication band B2 may also transmit signals at power B1.

Based on the above analysis, in order to determine how to control the operation mode of the positioning module, it is necessary to first obtain the signal transmission power of the communication module. For example, the transmission power of the signal may be detected by a detection module disposed in the communication module, for example, the detection module may be a Feedback RX (FBRX). For another example, the signal transmission power of the communication module may be monitored by an application running in the electronic device, so as to obtain the signal transmission power of the communication module.

Step S120: and controlling the positioning module to be in a designated working mode when the signal transmitting power is greater than a target power threshold, wherein the positioning module works in an interval in which the communication module does not transmit signals and does not work in an interval in which the communication module transmits signals in the designated working mode.

For some embodiments, as can be seen from the analysis of the foregoing steps, when the signal transmission power of the communication module is higher, the interference caused to the positioning module is also higher, and when the signal transmission power of the communication module is lower, the interference caused to the positioning module is smaller. Therefore, the target power threshold value can be used as a reference, and if the signal transmission power is greater than the target power threshold value, it can be determined that the signal transmission power of the communication module is greater, and the interference caused to the positioning module is also greater at this time; if the signal transmission power is not greater than the target power threshold, it may be determined that the signal transmission power of the communication module is smaller, and the interference caused to the positioning module is also smaller. The target power threshold may be used to represent a critical value, and when the signal transmission power is greater than the critical value, the signal transmitted by the communication module may cause large interference to the positioning module; when the signal transmission power is not greater than the critical value, the signal transmitted by the communication module causes less interference to the positioning module.

Further, as can be seen from the foregoing description of the steps, the communication module may include a plurality of communication frequency bands. Since different frequency bands in the communication module have different interference capabilities on the positioning module, it is easy to understand that the target power thresholds corresponding to the transmission signals of different frequency bands are different. For example, the transmission signal is a frequency band X, the corresponding target power threshold may be X1, the transmission signal is a frequency band Y, and the corresponding target power threshold may be Y1. Therefore, before determining the magnitude relation between the signal transmission power and the target power threshold, the frequency band of the signal transmitted by the communication module may also be obtained, and then the corresponding target power threshold is determined based on the frequency band. For a specific method for obtaining the target power threshold, reference may be made to the following embodiments.

Further, as can be seen from the above analysis, if the signal transmission power is greater than the target power threshold, it represents that the signal transmission power of the communication module is greater at this time, and the interference caused to the positioning module is also greater. Thus, the positioning module can be controlled to be in a specified operation mode at this time. Specifically, the positioning module operates in the designated operating mode in an interval in which the communication module does not transmit a signal, and does not operate in an interval in which the communication module transmits a signal. Specifically, referring to fig. 5, fig. 5 is a schematic diagram illustrating a positioning system being controlled to operate in a specific operation mode. In the graph shown in fig. 5, the horizontal axis represents time in ms, a curve f3 represents the operating state of the positioning system, and a curve f4 represents the operating state of the communication system, where the positioning module does not operate when the curve f3 is at a low level, and the positioning module operates when the curve f3 is at a high level; the communication module does not transmit a signal when the curve f4 is low, and transmits a signal when the curve f4 is high. It can be seen that the positioning module operates in the designated operating mode in the interval in which the communication module does not transmit signals, and does not operate in the interval in which the communication module transmits signals. For some embodiments, the specified mode of operation may also be referred to as blanking (blanking) operation.

It should be noted that, in the designated operation mode, the positioning module operates in the interval in which the communication module does not transmit signals. Specifically, the job may be in a state of being always in a state of being able to meet the task requirement at any time, and when there is a task requirement, the task requirement may be directly processed. The task requirement may be generated and sent by an application program run by the electronic device, for example, the application program may be a map application program, and the map application program may generate the task requirement for acquiring the position of the current electronic device, and send the task requirement to the positioning module through the main control module.

Alternatively, a time period may be divided into a plurality of segments, where each segment is the minimum time unit for the communication module to transmit signals. For example, the communication module may transmit signals for 1 segment of the time period, while the remaining segments of the time period do not transmit signals. Each segment is also the smallest unit of time for which the positioning module is to operate. For example, the positioning module may be inactive for 2 segments of the time period, while other segments of the time period are active. For example, in the Long Term Evolution (LTE) standard defined by the third Generation Partnership Project (3 GPP), the one period may be one data frame duration, which is 10ms, wherein each data frame duration may be divided into 10 slots Slot. The communication module may transmit signals in 1 slot within the data frame duration and not transmit signals in the remaining 9 slots within the data frame duration. The positioning module may be controlled to be not operated in 1 timeslot of the data frame duration during which the communication module transmits signals, and to be operated in the remaining 9 timeslots of the data frame duration. For example, if 10 slots in the data frame duration are t1, t2, t3, t4, t5, t6, t7, t8, t9 and t10, respectively, the communication module may transmit a signal in the t2 slot in the data frame duration, and not transmit a signal in the remaining 9 slots in the data frame duration. The positioning module may be controlled to be not operated at t2 time slots within the data frame duration and to be operated at the remaining 9 time slots within the data frame duration.

Step S130: and if the signal transmitting power is not greater than the target power threshold, controlling the positioning module to continuously work.

For some embodiments, it can be seen from the above analysis that when the signal transmission power of the communication module is smaller, the interference to the positioning module is smaller. And because the control positioning module does not work, the positioning sensitivity of the positioning module can be reduced, and therefore when the signal transmitting power of the communication module is smaller, the positioning module can be controlled to work continuously, and the reduction of the positioning sensitivity of the positioning module caused by the fact that the positioning module does not work is avoided.

Specifically, if the signal transmission power is not greater than the target power threshold, the positioning module may be controlled to continuously operate. The continuous work can be in a state of being always connected with the task requirement at any time, and the task requirement can be directly processed when the task requirement exists. The positioning module can be in a low power consumption state which can be awakened at any time, such as a standby state, at the moment, the positioning module can keep low power consumption and can be awakened by the task requirement in time, and therefore the task requirement is processed after the positioning module is awakened by the task requirement. The application is not specifically limited in operation. The task requirement may be generated and sent by an application program run by the electronic device, and the task requirement is explained in the foregoing steps, which is not described herein again.

According to the control method, the control device, the electronic equipment and the storage medium, firstly, the signal transmitting power of the communication module is obtained, if the signal transmitting power is larger than a target power threshold value, the positioning module is controlled to be in a designated working mode, and if the signal transmitting power is not larger than the target power threshold value, the positioning module is controlled to continuously work. Because the positioning module is greatly interfered when the signal transmitting power of the communication module is larger, when the communication module transmits signals with larger signal transmitting power, the positioning module can be controlled to work in the interval that the communication module does not transmit signals and does not work in the interval that the communication module transmits signals; when the signal transmitting power is low, the positioning module is controlled to continuously work, so that the interference of the communication module on the positioning module can be reduced and the positioning sensitivity of the positioning module can be improved when the communication module transmits signals with high signal transmitting power; and when the communication module transmits signals with smaller signal transmitting power, the positioning sensitivity of the positioning module is improved by continuous operation.

Referring to fig. 6, fig. 6 shows a control method provided in the embodiment of the present application, which can be applied to the main control module 110 in the electronic device 100 in the foregoing embodiment, where the electronic device further includes a communication module 120 and a positioning module 130. The main control module 110 is connected to the positioning module 130 and the communication module 120, respectively. Specifically, the method includes steps S210 to S230.

Step S210: and acquiring the signal transmitting power of the communication module.

Through the foregoing analysis, the communication module may transmit signals of different frequencies, and the signals of different frequencies may correspond to different target power thresholds. Therefore, when the signal transmission power of the communication module is obtained, a target signal frequency band and a target power threshold value can be determined, wherein the target signal frequency band is a frequency band corresponding to the signal transmitted by the communication module. Specifically, referring to fig. 7, fig. 7 shows an implementation of step S210, which includes steps S310 to S340.

Step S310: and acquiring the signal transmitting power of the communication module.

Step S310 has already been described in detail in the foregoing embodiments, and is not described herein again.

Step S320: and acquiring a target signal frequency band currently used by the communication module.

For some embodiments, a detection module may be added to the communication module, and configured to detect a frequency band of a signal transmitted by the current communication module, that is, a target signal frequency band, and then send the obtained target signal frequency band to the main control module. For other embodiments, multiple frequency bands to which signals transmitted by the communication module may correspond may be stored in the electronic device in advance, so that each frequency band may be assigned with a corresponding identifier to generate an identifier table, when the communication module transmits a signal, an identifier of a currently used frequency band may be generated, and after the main control module acquires the identifier from the communication module, the main control module searches for the frequency band corresponding to the acquired identifier from the stored identifier table, that is, the target signal frequency band may be acquired. For example, if the frequency bands corresponding to the signals transmitted by the communication module are stored in advance, the frequency bands may include: frequency band a, frequency band B, and frequency band C, the frequency band a may be given an identifier 1, the frequency band B may be given an identifier 2, the frequency band C may be given an identifier 3, and an identifier table may be generated based on the frequency band a, the identifier 1, the frequency band B, the identifier 2, the frequency band C, and the identifier 3. When the communication module transmits a signal, an identifier corresponding to the signal frequency band, for example, the identifier 2, may be generated, and after the main control module obtains the identifier 2, the frequency band corresponding to the identifier 2 may be found to be B based on the identifier table, that is, the target signal frequency band may be determined to be B. It should be noted that, the method for acquiring the target signal frequency band is not limited in the present application.

Step S330: a target power threshold is determined based on the target signal band.

As can be seen from the above analysis, different target signal frequency bands may correspond to different target power thresholds, so that the target power thresholds corresponding to the signals of different frequency bands may be predetermined, and then the target power threshold corresponding to the target signal frequency band is determined based on the obtained target signal frequency band. Specifically, referring to fig. 8, fig. 8 shows an implementation diagram of step S330, which includes step S410 and step S420.

Step S410: the method comprises the steps of obtaining a frequency power comparison table, wherein the frequency power comparison table comprises a plurality of signal frequency bands which can be used by a communication module and a power threshold corresponding to each signal frequency band, and the power threshold of each signal frequency band is used for representing that the positioning sensitivity of a positioning module is not met with a specified condition due to a transmitted signal under the condition that the power value of the signal transmitted by the communication module is larger than the power threshold.

For some embodiments, it can be known from the foregoing embodiments that the signal transmitted by the communication module may correspond to multiple frequency bands, that is, there are multiple signal frequency bands. Therefore, the corresponding power threshold value can be obtained based on each signal frequency band, and each signal frequency band and the corresponding power threshold value form a frequency power comparison table. The frequency bands that can be used by the communication module are related to the design and type selection of the communication module, for example, the frequency bands that can be used by the communication module N1 include a1, B1 and C1, and the frequency bands that can be used by the communication module N2 include a1, B1, C1 and D1. The frequency band specifically used by the communication module is not limited, and can be flexibly adjusted according to the requirement.

Further, due to the different interference abilities of the different signal bands transmitted by the communication modules to the positioning module, for example, under the condition that the powers corresponding to the signal bands are the same, the signal band a1 may reduce the positioning sensitivity of the positioning module by 2dB, the signal band a2 may reduce the positioning sensitivity of the positioning module by 3dB, and the signal band A3 may reduce the positioning sensitivity of the positioning module by 5 dB. Therefore, a specified condition for the positioning sensitivity of the positioning module can be set, then different powers corresponding to each signal frequency band are tested, when the power causes the corresponding signal frequency band to interfere with the positioning module so that the positioning sensitivity just can meet the specified condition, and the power slightly larger than the power causes the corresponding signal frequency band to interfere with the positioning module so that the positioning sensitivity does not meet the specified condition, the power can be determined as the target power corresponding to the signal frequency band. The target power corresponding to each signal frequency band can be sequentially obtained according to the method, and a frequency power comparison table is generated.

For example, the specified condition may be that the positioning sensitivity is reduced by no more than 5 dB. If the signal frequency band A1 is under the condition of power P1, interference is generated on a positioning module, so that the positioning sensitivity is reduced by 3 dB; in the case of power P2, the positioning sensitivity is reduced by 4 dB; at power P3, the positioning sensitivity is reduced by 5 dB. At this time, the power P2 makes the corresponding signal band a1 lower the positioning sensitivity by 5dB, just meeting the specified condition, and when the power is greater than P3, the signal band a1 lowers the positioning sensitivity by more than 5dB, i.e., the specified condition is not met, so that the power P2 can be used as the target power threshold at this time.

Step S420: and searching a power threshold corresponding to the target signal frequency band in the frequency power comparison table to be used as a target power threshold.

For some embodiments, the frequency power comparison table and the target signal frequency band have been obtained in the above step, so that the target power threshold corresponding to the target signal frequency band can be directly searched through the frequency power comparison table. That is, a signal frequency band identical to the target signal frequency band may be searched in the frequency-power comparison table, and then the target power threshold corresponding to the signal frequency band is used as the target power threshold corresponding to the target signal frequency band.

Step S340: and judging whether the signal transmitting power is larger than a target power threshold value or not.

For some embodiments, after the signal transmission power and the target power threshold are obtained in the above steps, it may be determined whether the signal transmission power is greater than the target power threshold, that is, the magnitude relationship between the signal transmission power and the target power threshold may be determined. For one example, the magnitude relationship of the signal transmit power to the target power threshold may be directly compared; it is also possible to obtain a difference between the signal transmission power and the target power threshold, and then determine the magnitude relationship between the signal transmission power and the target power threshold based on the difference. Specifically, when the difference is less than zero, it can be known that the signal transmission power is less than the target power threshold; when the difference is greater than zero, the signal transmitting power is greater than the target power threshold value; when the difference is equal to zero, it can be known that the signal transmission power is equal to the target power threshold. It should be noted that, the method for determining whether the signal transmission power is greater than the target power threshold is not limited in this application.

Step S220: and if the signal transmitting power is greater than a target power threshold, controlling the positioning module to be in a specified working mode, and executing specified filtering operation on the signal transmitted by the communication module.

For some embodiments, it can be seen from the analysis in the foregoing embodiments that the communication module may cause interference to the positioning module when transmitting a signal, so that the positioning sensitivity of the positioning module is reduced. When the signal transmitting power of the communication module is higher, the interference caused to the positioning module is also higher, and when the signal transmitting power of the communication module is lower, the interference caused to the positioning module is lower. The positioning module can be controlled not to work when the signal transmitting power of the communication module is larger, so that the interference of the communication module to the positioning module is reduced, and the positioning sensitivity of the positioning module is improved.

Further, when the signal transmission power of the communication module is high, the interference caused to the positioning module is also high, so that the communication module can perform the specified filtering operation at this time. It will be readily appreciated that the specified filtering operation is intended to reduce interference caused to the positioning module by signals transmitted by the communication module. The signals transmitted by the communication module may include in-band signals and out-of-band signals, general out-of-band signals may be regarded as noise signals, and when the frequency band of the out-of-band signals intersects with the frequency band of the positioning module, the out-of-band signals may interfere with the positioning module, thereby reducing the positioning sensitivity of the positioning module. For example, if the frequency band of the in-band signal of the signal transmitted by the communication module is a1, the frequency band of the in-band signal includes a2 and a3, and if the frequency band of the positioning module is also a2, the a2 frequency band portion of the in-band signal of the signal transmitted by the communication module may interfere with the positioning module, so that the positioning sensitivity of the positioning module is reduced. Therefore, at this time, the in-band signal corresponding to the a2 frequency band in the above example can be further filtered by specifying a filtering operation, so that the strength of the in-band signal corresponding to the a2 frequency band is reduced, thereby reducing the interference to the positioning module. For example, if the intensity of the in-band signal corresponding to the a2 frequency band is-40 dBm in the above example, and the specified filtering operation can reduce the intensity of the in-band signal corresponding to the a2 frequency band by 20dB, the intensity of the in-band signal corresponding to the a2 frequency band that causes interference to the positioning module at this time is-60 dBm, so as to improve the positioning sensitivity of the positioning module.

Optionally, since the frequency band corresponding to the positioning module has a lower frequency than the frequency band of the signal transmitted by the communication module, the specified filtering operation may be low-pass filtering. For example, if the central frequency band of the signal transmitted by the communication module is 1880-1920MHz, the out-of-band signal is distributed around the frequency band of about 1500MHz-2500MHz, and the frequency band corresponding to the positioning module is 1575.42MHz, where the out-of-band signal covers 1575.42MHz corresponding to the positioning module, and therefore when the signal transmission power of the communication module is higher, the power corresponding to the out-of-band signal is also higher, which may cause interference to the positioning module. At this time, the signal strength of the frequency band near the out-of-band signal 1500Mhz may be attenuated by low-pass filtering, for example, 1500Mhz-1700Mhz is filtered, so as to reduce the interference of the out-of-band signal to the positioning module.

Step S230: and if the signal transmitting power is not greater than the target power threshold, controlling the positioning module to continuously work.

For some embodiments, it can be known from the above analysis that when the signal transmission power of the communication module is smaller, the interference to the positioning module is smaller. And because the strength of the out-of-band frequency band of the signal transmitted by the communication module is in positive correlation with the signal transmission power, when the signal transmission power of the communication module is low, the strength of the signal of the out-of-band frequency band is also low, that is, the interference of the signal of the out-of-band frequency band to the positioning module is low.

Furthermore, because the specified filtering operation is performed on the communication module, an additional filtering module is introduced, so that the overall insertion loss in the communication module is increased, and the working efficiency of the communication module is reduced.
