Description

Anti-interference method and device

Technical Field

Background

With the development and popularization of mobile communication technology, mobile terminals (such as mobile phones, tablet computers and the like) have become an indispensable part of life and work of people.

The rapid development and the maturation of the screen display technology, the application of the high-definition display screen in the mobile terminal is more and more popular, and the high screen occupation ratio and the high-definition display are important indexes for consumers to select the mobile terminal at present. However, the "high screen ratio and high definition display" pose a great challenge to the design of the mobile terminal, and the driver IC of the LCM (LCD Module) is closer to the antenna, and the interference generated by the driver IC is more easily coupled to the antenna to interfere with the communication quality of the mobile terminal.

In order to solve the above problems, the following methods are generally adopted: shielding and filtering of an LCM driver part are enhanced, but the use of LCM grounding shielding measures is structurally limited by the current design requirement of high screen ratio and ultrathin, interference signals cannot be completely shielded, and hardware cost is increased. An appropriate LCM MIPI (Mobile Industry Processor Interface) clock frequency can also be selected.

However, as the frequency bands supported by the mobile terminal increase more and more, the mode of setting a single LCM MIPI clock frequency can only ensure that the MIPI interference frequency point does not fall within the receiving band of a certain frequency band, but cannot ensure that the MIPI interference frequency point does not fall within the receiving bands of other frequency bands supported by the mobile terminal, thereby causing the communication quality of the mobile terminal to be interfered.

A monitoring program of the screen state can be preset in the terminal equipment system, and the screen state of the terminal equipment can be acquired in real time through the monitoring program.

Of course, in a specific implementation, a person skilled in the art may also obtain the state of the screen of the terminal device in other manners, and specifically, the state may be determined according to a service requirement, which is not limited in this embodiment of the present invention.

The working mode refers to a mode in which the dual communication frequency points of the terminal device work simultaneously or a working mode of the single communication frequency point, and the dual frequency point working mode or the single frequency point working mode will be described in detail in the following process, which is not described herein again in the embodiments of the present invention.

When the screen of the terminal equipment is changed from off to on or the terminal equipment works in the on state, the terminal equipment monitors the self-registered network event and judges the working mode of the terminal equipment.

Of course, an identification program of the operation mode may be preset in the system, and when the terminal device is in a communication state, the operation mode of the terminal device may be identified by the identification program.

In practical application, a person skilled in the art may also obtain the operating mode of the terminal device in other manners, which may be determined according to service requirements, and the embodiment of the present invention is not limited thereto.

After determining the operation mode of the terminal device, step 102 is executed.

Step 102: and under the condition that the working mode is a double-frequency-point working mode, acquiring a first working frequency corresponding to a mobile industrial processor interface (LCM MIPI) of the liquid crystal module.

The Dual frequency point operating mode is a mode in which two communication frequency points operate simultaneously in the terminal device, and the Dual frequency point operating mode may be a CA (Carrier Aggregation) mode or an EN-DC (EUTRA-NR Dual Connectivity, 4G-5G Dual Connectivity) mode, which may be determined according to actual conditions.

The first working frequency is the working frequency of the mobile industry processor interface LCM MIPI of the liquid crystal module during communication of the terminal equipment.

In the process of communication of the terminal device, the scheme of acquiring the first operating frequency of the LCM MIPI is a mature technology in the field, and the embodiment of the present invention is not described in detail herein.

Under the condition that the operating mode of the terminal device is the dual-frequency-point operating mode, a first operating frequency corresponding to the LCM MIPI may be obtained, and step 103 is executed.

Step 103: and acquiring a first received signal strength corresponding to the first communication frequency point and a second received signal strength corresponding to the second communication frequency point.

The received signal strength refers to the signal strength of the information sent by the base station and received by the terminal equipment through the communication frequency point.

The first communication frequency point and the second communication frequency point are two communication frequency points which work simultaneously when the terminal equipment is in a double-frequency-point working mode.

The first receiving signal strength is the receiving signal strength of the information sent by the receiving base station when the first communication frequency point works, and the second receiving signal strength is the receiving signal strength of the information sent by the receiving base station when the second communication frequency point works.

It can be understood that the scheme for obtaining the received signal strength corresponding to the communication frequency point is a mature technology in the field, and any scheme capable of obtaining the received signal strength of the communication frequency point in the prior art may be applied to the embodiment of the present invention, and the embodiment of the present invention is not described in detail herein.

When the terminal device is in the dual-frequency-point operating mode, step 104 may be executed after a first received signal strength corresponding to the first communication frequency point and a second received signal strength corresponding to the second communication frequency point are respectively obtained.

Step 104: and under the condition that the first working frequency is a first threshold frequency, determining whether the first communication frequency point is a first interference frequency point corresponding to the first threshold frequency.

The first threshold frequency refers to a frequency threshold preset by a service person, and a specific value of the first threshold frequency may be determined according to an actual situation, which is not limited in the embodiment of the present invention.

In a specific application process, two threshold frequencies, namely a first threshold frequency and a second threshold frequency (namely, the threshold frequencies mentioned in the following steps) may be set for different frequency points in a dual frequency point working mode, and the process of acquiring the first threshold frequency and the second threshold frequency may be described in detail in the following embodiment two, which is not described herein again.

In order to ensure the display quality and stability of the LCM, the clock frequency (i.e., the first threshold frequency and the second threshold frequency) of the LCM MIPI needs to be selected to meet the requirement of the driver IC, and the absolute value of the difference between the first threshold frequency and the second threshold frequency should be less than 5 MHz.

The detailed description of the first threshold frequency and the second threshold frequency will be described in detail in the following embodiments.

It should be understood that although the terms first and second may be used to describe the threshold frequencies in the embodiments of the present invention, the threshold frequencies should not be limited to these terms. These terms are only used to distinguish threshold frequencies from each other. For example, the first threshold frequency may also be referred to as the second threshold frequency, and similarly, the second threshold frequency may also be referred to as the first threshold frequency, without departing from the scope of embodiments of the present invention.

After obtaining the first operating frequency of the terminal device, the first operating frequency may be compared with a first threshold frequency (or a second threshold frequency, which is a comparison and determination process performed with the first threshold frequency in the embodiment of the present invention) to determine whether the first operating frequency is the same as the first threshold frequency, specifically, whether the first operating frequency is substantially the same as the first threshold frequency, for example, a difference is not greater than 0.5Hz, and the like, and specifically, may be determined according to a service requirement.

The first interference frequency point is an interference frequency point corresponding to a first threshold frequency, the first threshold frequency may correspond to a plurality of frequency bands, each frequency band simultaneously includes one or more frequency points, and the frequency points are interference frequency points.

The first communication frequency point refers to one communication frequency point when the terminal equipment works by adopting the dual communication frequency points.

Under the condition that the first working frequency is the first threshold frequency, it may be determined whether the first communication frequency point is the first interference frequency point corresponding to the first threshold frequency, for example, the first communication frequency point may be matched with a plurality of interference frequency points corresponding to the first threshold frequency, and when the matching is successful, the matched interference frequency point is used as the first interference frequency point, that is, the first communication frequency point is also used as the first interference frequency point.

It should be understood that the above-mentioned schemes are only examples for better understanding of the technical schemes of the embodiments of the present invention, and are not to be taken as the only limitation of the embodiments of the present invention.

And when the first communication frequency point is determined to be the first interference frequency point corresponding to the first threshold frequency, executing step 105.

Step 105: and determining the magnitude relation between the first received signal strength and a first signal threshold strength corresponding to the first threshold frequency under the condition that the first communication frequency point is the first interference frequency point.

The first signal threshold strength refers to a signal threshold strength corresponding to a first threshold frequency.

In the invention, after the first threshold frequency is set, when the terminal device works by adopting one or more frequency points of a plurality of frequency bands according to the first threshold frequency, the received signal intensity corresponding to each frequency point respectively can be determined, and then the first signal threshold intensity can be determined according to the plurality of received signal intensities.

The process of obtaining the first signal threshold strength is described in detail in the following embodiment two, which is not repeated herein.

When the first communication frequency point is the first interference frequency point, the first received signal strength may be compared with a first signal threshold strength corresponding to the first threshold frequency, so as to determine a magnitude relationship between the first received signal strength and the first signal threshold strength corresponding to the first threshold frequency.

In the case that the first received signal strength is greater than the first signal threshold strength, a process of determining whether the second communication frequency point is an interference frequency point corresponding to the first threshold frequency may be performed.

And in the case that the first received signal strength is less than or equal to the first signal threshold strength, step 106 is performed.

Step 106: and determining whether the second communication frequency point is a second interference frequency point corresponding to a second threshold frequency or not under the condition that the strength of the first received signal is less than or equal to the strength of the first signal threshold.

The second interference frequency point refers to an interference frequency point corresponding to the second threshold frequency, and it can be understood that the description process of the second interference frequency point may be similar to that of the first interference frequency point, and the embodiment of the present invention is not described in detail herein.

When the first received signal strength is less than or equal to the first signal threshold strength, it may be determined whether the second communication frequency point is a second interference frequency point corresponding to the second threshold frequency, for example, the second communication frequency point may be matched with a plurality of interference frequency points corresponding to the second threshold frequency, and when the matching is successful, the matched interference frequency point is used as the second interference frequency point, that is, the second communication frequency point is used as the second interference frequency point.

After determining that the second communication frequency point is the second interference frequency point, step 107 is executed.

Step 107: and determining the magnitude relation between the second received signal strength and a second signal threshold strength corresponding to the second threshold frequency under the condition that the second communication frequency point is the second interference frequency point.

The second signal threshold strength refers to a signal threshold strength corresponding to the second threshold frequency.

In the invention, after the second threshold frequency is set, when the terminal device works by adopting one or more frequency points of a plurality of frequency bands according to the second threshold frequency, the received signal intensity corresponding to each frequency point respectively can be further determined according to the plurality of received signal intensities.

The process of obtaining the two signal threshold intensities will be described in detail in the following embodiment two, which is not repeated herein.

When the second communication frequency point is determined to be the second interference frequency point, the second received signal strength may be compared with a second signal threshold strength corresponding to the second threshold frequency, so as to determine a magnitude relationship between the second received signal strength and the second received signal strength.

After determining the magnitude relationship between the second received signal strength and the second signal threshold strength, step 108 is performed.

Step 108: adjusting the first operating frequency to the second threshold frequency if the second received signal strength is greater than the second signal threshold strength.

When the strength of the second received signal is less than or equal to the strength of the second signal threshold, it indicates that the network states are poor at this time, and adjusting the first operating frequency to the second threshold frequency causes greater interference to the second communication frequency point, and then the first operating frequency is continuously maintained.

And under the condition that the strength of the second received signal is greater than the strength of the second signal threshold, the network state of the second communication frequency point is better at the moment, and the first working frequency can be adjusted to the second threshold frequency, so that the influence of the LCM MIPI on the communication quality can be improved.

The embodiment of the invention can improve the influence of LCM MIPI on the communication quality by judging the working frequency of the terminal equipment and the current received signal strength and adopting a corresponding working frequency switching mode.

The interference preventing method provided by the embodiment of the invention determines the working mode of the terminal equipment under the condition that the screen of the terminal equipment is in a bright screen state, acquires the first working frequency corresponding to the mobile industry processor interface LCM MIPI of the liquid crystal module under the condition that the working mode is the double-frequency-point working mode, acquires the first received signal intensity corresponding to the first communication frequency point and the second received signal intensity corresponding to the second communication frequency point, determines whether the first communication frequency point is the first interference frequency point corresponding to the first threshold frequency or not under the condition that the first working frequency is the first threshold frequency, determines the magnitude relation between the first received signal intensity and the first signal threshold intensity corresponding to the first threshold frequency under the condition that the first communication frequency point is the first interference frequency point, and determines the magnitude relation between the first received signal intensity and the first signal threshold intensity corresponding to the first threshold frequency under the condition that the first received signal intensity is less than or equal to the first signal threshold intensity, and determining whether the second communication frequency point is a second interference frequency point corresponding to a second threshold frequency, determining the magnitude relation between the second received signal strength and the second signal threshold strength corresponding to the second threshold frequency when the second communication frequency point is the second interference frequency point, and adjusting the first working frequency to the second threshold frequency when the second received signal strength is greater than the second signal threshold strength. In the embodiment of the invention, under the scene of a double-frequency-point working mode (such as carrier aggregation or 4G-5G double connection and the like), the terminal equipment simultaneously uses 2 or more communication frequency points, and the influence of LCM MIPI on the communication quality can be improved and the user experience is improved by judging the working frequency of the terminal equipment and the current received signal strength and adopting a corresponding working frequency switching mode.

Example two

Referring to fig. 2, a flowchart of steps of an interference prevention method provided in an embodiment of the present invention is shown, where the interference prevention method may be applied to a terminal device, and specifically may include the following steps:

step 201: setting the first threshold frequency and the second threshold frequency corresponding to the LCM MIPI.

In the embodiment of the present invention, the terminal Device may be a mobile electronic Device such as a mobile phone and a PAD (tablet Android Device), and may also be an electronic Device such as a desktop computer and a notebook computer.

In the design stage, two sets of appropriate clock frequencies, namely a first threshold frequency (denoted as F1) and a second threshold frequency (denoted as F2), can be selected according to the frequency band required to be supported by the terminal device and the requirement of the driving IIC, and under the condition of ensuring the display quality and reliability of the LCM.

Of course, the absolute value of the difference between the first threshold frequency and the second threshold frequency should be less than 5MHz, i.e. | | F1-F2| | < 5 MHz.

It can be understood that the first threshold frequency and the second threshold frequency are preset by a service person according to actual requirements, and for a specific setting process, the embodiments of the present invention are not described herein again.

The second frequency point is a frequency point corresponding to a second threshold frequency, and the second threshold is a signal intensity threshold corresponding to the second frequency point.

Under the condition of two LCM MIPI clock frequencies found in a laboratory, the receiving sensitivity of interference frequency points of each frequency band of the terminal equipment in a bright screen state can be generated into a list as shown in the following table 1.

as shown in table 1, the first threshold frequency F1 corresponds to the interference frequency points a1, a2, and AN, and the receiving sensitivities corresponding to the interference frequency points are X1, X2, and XN, respectively; f2 corresponds to interference frequency points B1, B2, and BN, and the reception sensitivity of each interference frequency point is Y1, Y2,.

It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present invention, and are not to be taken as the only limitation of the embodiments of the present invention.

After acquiring the plurality of first frequency points and the first threshold corresponding to each first frequency point, and the plurality of second frequency points and the second threshold corresponding to each second frequency point, step 204 is executed.

Step 204: a first minimum threshold value of the plurality of first threshold values and a second minimum threshold value of the plurality of second threshold values are obtained.

The first minimum threshold refers to a minimum threshold of the plurality of first thresholds, for example, the first threshold includes 1, 3, and 5, and the first minimum threshold is 1.

The second minimum threshold refers to a minimum threshold of the plurality of second thresholds, for example, the second threshold includes 2, 3, and 8, and the first minimum threshold is 2.

After acquiring the plurality of first threshold values and the plurality of second threshold values, a first minimum threshold value and a second minimum threshold value may be acquired from the plurality of first threshold values and the plurality of second threshold values, respectively, and step 205 and step 206 are performed.

Step 205: and acquiring the first signal threshold strength based on the first minimum threshold and a preset value.

Step 206: and acquiring the second signal threshold strength based on the second minimum threshold and the preset value.

The preset value is a preset tightening value, tightening is performed on the obtained first minimum threshold and the second minimum threshold, and specifically, after the first minimum threshold is obtained, the first minimum threshold and the preset value may be added to add the first minimum threshold to tighten the first minimum threshold; after the second minimum threshold is obtained, the second minimum threshold and the preset value may be added to add the second minimum threshold to tighten the second minimum threshold, for example, if the preset value is n, the first minimum threshold + n is the first signal threshold strength, and the second minimum threshold + n is the second signal and the previous strength.

Step 214: adjusting the first operating frequency to the second threshold frequency if the second received signal strength is greater than the second signal threshold strength.

In the embodiment of the present invention, the specific implementation manner of the step 207 to the step 214 is similar to the specific implementation manner of the step 101 to the step 108 in the first embodiment, and the specific implementation process may refer to the description of the step 101 to the step 108, which is not described herein again in the embodiment of the present invention.

Of course, in a preferred embodiment of the present invention, when the first communication frequency point is not the first interference frequency point, whether the second communication frequency point is the first interference frequency point may be determined, and specifically, the following preferred embodiment is described in detail.

In a preferred embodiment of the present invention, after the step 210, the method may further include:

step A1: and determining whether the second communication frequency point is the first interference frequency point or not under the condition that the first communication frequency point is not the first interference frequency point.

In the embodiment of the present invention, when the first communication frequency point is not the interference frequency point corresponding to the first threshold frequency, that is, the first communication frequency point is not the first interference frequency point, it may be determined whether the second communication frequency point is the first interference frequency point

Step A3: and determining whether the first communication frequency point is the second interference frequency point or not under the condition that the strength of the second received signal is less than or equal to the strength of the first signal threshold.

Under the condition that the strength of the second received signal is less than or equal to the strength of the first signal threshold, whether the first communication frequency point is a second interference frequency point corresponding to the second threshold frequency can be determined, that is, whether the first communication frequency point is one of a plurality of interference frequency points corresponding to the second threshold frequency is determined.

After the first communication frequency point is determined to be the second interference frequency point, step a4 is executed.

Step A4: and determining the magnitude relation between the first received signal strength and the second signal threshold strength under the condition that the first communication frequency point is the second interference frequency point.

After determining that the first communication frequency point is the second interference frequency point, the magnitude relationship between the first received signal strength and the second signal threshold strength may be compared, and step a5 is performed.

Step A5: adjusting the first operating frequency to the second threshold frequency if the first received signal strength is greater than the second signal threshold strength.

Under the condition that the strength of the first received signal is greater than the strength of the second signal threshold, the first operating frequency can be adjusted to the second threshold frequency, so that the influence of the LCM MIPI on the communication quality can be improved.

Of course, in another preferred embodiment of the present invention, the step of determining whether the second communication frequency point is the first interference frequency point may be performed when the first received signal strength is compared with the first signal threshold strength and the first received signal strength is greater than the first signal threshold strength, that is, the steps a1 to a5 may be performed when the first received signal strength is greater than the first signal threshold strength

Step 215: and under the condition that the working mode is a single-frequency-point working mode, obtaining a second working frequency corresponding to the LCM MIPI.

Step 216: and acquiring the single-point received signal strength corresponding to the single communication frequency point.

The single-point received signal strength refers to the received signal strength corresponding to a single communication frequency point, that is, the received signal strength when the single communication frequency point adopted by the terminal equipment works and the single communication frequency point receives information from the base station,

It can be understood that the technology for obtaining the received signal strength of the communication frequency point is a mature technology in the field, any scheme capable of obtaining the received signal strength of the communication frequency point in the prior art can be applied to the present invention, and the detailed process for obtaining the single-point received signal strength corresponding to the single communication frequency point is not described herein again in the embodiments of the present invention.

After acquiring the strength of the single-point received signal corresponding to the single communication frequency point, step 217 is performed.

Step 217: and determining whether the single communication frequency point is a target interference frequency point corresponding to the first threshold frequency or the second threshold frequency under the condition that the second working frequency is the first threshold frequency or the second threshold frequency.

After the second operating frequency of the LCM MIPI is obtained, it may be determined whether the second operating frequency is the first threshold frequency or the second threshold frequency, that is, whether the second operating frequency is the first threshold frequency or the second threshold frequency, for example, when the second operating frequency is the first threshold frequency, the step of determining whether the second operating frequency is the second threshold frequency is not executed; and when the second working frequency is not the first threshold frequency, executing the step of judging whether the second working frequency is the second threshold frequency.

The target interference frequency point refers to one of a plurality of interference frequency points corresponding to the single communication frequency point which is the first threshold frequency or the second threshold frequency.

After the second working frequency is determined to be the first threshold frequency or the second threshold frequency, whether the single communication frequency point is the target interference frequency point or not can be judged.

After determining whether the single communication frequency point is the target interference frequency point, step 218 is executed.

Step 218: and under the condition that the single communication frequency point is the target interference frequency point, determining the magnitude between the single-point received signal strength and the first signal threshold strength or the second signal threshold strength.

Under the condition that the single communication frequency point is the target interference frequency point, the magnitude relation between the single point received signal strength and the first signal threshold strength or the second signal threshold strength can be compared.

Specifically, when the single communication frequency point is the target interference frequency point corresponding to the first threshold frequency, the magnitude between the single-point received signal strength and the first signal threshold strength may be compared; and when the single communication frequency point is the target interference frequency point corresponding to the second threshold frequency, the strength between the single point received signal strength and the second signal threshold strength can be compared.

After comparing the magnitude between the single-point received signal strength and the first signal threshold strength or the second signal threshold strength, step 219 is performed.

Step 219: adjusting the second operating frequency from the first threshold frequency or the second threshold frequency to the second threshold frequency or the first threshold frequency if the single-point received signal strength is less than the first signal threshold strength or less than the second signal threshold strength.

In the case that the single-point received signal strength is less than the first signal threshold strength or the second signal threshold strength, the second operating frequency may be adjusted from the first threshold frequency or the second threshold frequency to the second threshold frequency or the first threshold frequency.

Specifically, when the single communication frequency point is the target interference frequency point corresponding to the first threshold frequency, the second operating frequency may be adjusted from the first threshold frequency to the second threshold frequency under the condition that the strength of the single-point received signal is smaller than the first signal threshold strength.

When the single communication frequency point is the target interference frequency point corresponding to the second threshold frequency, the second working frequency can be adjusted from the second threshold frequency to the first threshold frequency under the condition that the strength of the single-point received signal is less than the strength of the second signal threshold.
