Detailed Description
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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a flowchart of an implementation of a control method provided in an embodiment of the present application is shown, where the method may be applied to a communication terminal that includes a first component and a second component, such as a mobile phone that includes an antenna and a display screen. The technical scheme in the embodiment is used for improving the communication quality of the first component in the communication terminal.
Specifically, the method in this embodiment may include the following steps:
step 101: first communication parameters are obtained for use in operation of a first component in a communication terminal.
The first component may be a communication component in the communication terminal, such as an antenna, for performing data transmission with other terminals, where the antenna performs data transmission with other terminals according to corresponding communication parameters. The communication terminal also has a second component, which may be a communication component in the communication terminal for data transmission with a corresponding component in the communication terminal, such as a control Chip driver IC (Integrated Circuit Chip) of a Liquid Crystal Display LCD (Liquid Crystal Display), and the LCD driver IC performs data transmission with corresponding communication parameters with an internal component in the communication terminal, such as a CPU.
In particular, the component distance between the first component and the second component is less than the tamper resistance value, which may result in interference when the two are communicating simultaneously. For example, the LCD driver IC and the antenna are both located at the bottom of the screen of the mobile phone, and the mobile phone may interfere with the voice communication when performing the voice communication with other mobile phones and outputting pictures through the LCD driver IC.
It should be noted that the communication parameter in the present embodiment may be a communication frequency. For example, as shown in fig. 2, the antenna is registered to a specific band, the antenna operates on the band to realize voice communication with other terminals, and the LCD driver IC operates at a corresponding Mobile Industry Processor Interface (mipi) frequency to receive and display a picture transmitted by the CPU.
Step 102: and obtaining a second communication parameter according to the first communication parameter.
Wherein the second communication parameter does not overlap with the first communication parameter in communication frequency. For example, if the antenna is registered on the band-a, in this embodiment, a mipi frequency 2 that does not overlap with the band-a is obtained, where the mipi frequency 2 and its frequency multiplication do not overlap with the band-a; if the antenna is registered on the band-b, in this embodiment, the mipi frequency 1 which does not overlap with the band-b is obtained, wherein the mipi frequency 1 and the frequency multiplication thereof do not overlap with the band-b.
Step 103: and controlling the second component to operate according to the second communication parameter.
For example, in the mobile phone, the antenna is registered on the band-a, in this embodiment, by obtaining the mipi frequency 2 which does not overlap with the band-a, and the frequency multiplication of the mipi frequency 2, the LCD driver IC is controlled to perform the picture data transmission between the mipi frequency 2 and the CPU.
As can be seen from the foregoing solution, in a control method provided in the first embodiment of the present application, a first communication parameter used by a first component in a communication terminal to operate is obtained, and a second communication parameter that does not overlap with the first communication parameter on a communication frequency is obtained according to the first communication parameter, and then a second component in the communication terminal may be controlled to operate according to the second communication parameter, so that even if a component distance between the first component and the second component is smaller than an interference rejection value, communication interference between the first component and the second component may be avoided by controlling the first component and the second component to operate under non-overlapping communication parameters, respectively.
In one implementation, the step 102, when obtaining the second communication parameter according to the first communication parameter, may be implemented by:
and searching a second communication parameter which does not overlap with the first communication parameter on the communication frequency in a parameter list corresponding to the second component.
The parameter list includes a plurality of candidate communication parameters corresponding to the second component, as shown in fig. 3. The second component can operate with any one of the alternative communication parameters. Based on this, in this embodiment, the second communication parameter that does not overlap with the first communication parameter in the communication frequency may be screened out from the parameter list. For example, the LCD driver IC can perform frame data transmission with the CPU at any frequency of the mipi frequency 1 and the mipi frequency 2, and in this embodiment, after the band registered by the antenna is obtained, the mipi frequency that does not overlap with the band registered by the antenna in the frequency itself and the corresponding frequency multiplication can be selected from the parameter list of the LCD driver IC.
In one implementation, the step 102, when obtaining the second communication parameter according to the first communication parameter, may be implemented by:
and searching a second communication parameter which meets the first matching condition with the first communication parameter in a first matching list corresponding to the communication terminal.
The first matching list comprises a plurality of candidate communication parameters corresponding to the second component, each candidate communication parameter corresponding to the second component and at least one candidate communication parameter corresponding to the first component meet a first matching condition, and the first matching condition indicates that the candidate communication parameters are not overlapped on communication frequency. As shown in fig. 4, the first matching list includes a plurality of parameter sets, each parameter set includes one candidate communication parameter corresponding to the second component and at least one candidate communication parameter corresponding to the first component, and the candidate communication parameters in each parameter set satisfy a first matching condition, that is, the candidate communication parameters belonging to two components in each parameter set do not overlap with each other in communication frequency. Based on this, in this embodiment, after the first communication parameter is obtained, the parameter group corresponding to the first communication parameter, that is, the parameter group including the first communication parameter, is found in the first matching list, so that the candidate communication parameter corresponding to the second component in the parameter group including the first communication parameter is determined as the second communication parameter.
For example, the first matching list includes 2 parameter sets, where parameter set 1 includes the mipi frequency 2 of the LCD driver IC and the band1, band2, and band3 of the antenna, the mipi frequency 2 and its frequency multiplication and the band1, band2, and band3 of the antenna do not overlap in frequency, and parameter set 2 includes the mipi frequency 1 of the LCD driver IC and the band4, band5 of the antenna, and the mipi frequency 1 and its frequency multiplication and the band4, band5 of the antenna do not overlap in frequency, and based on this, after obtaining the band1 registered by the antenna, the mipi frequency in the same parameter set as band1, that is, mipi frequency 2, that is, the mipi frequency which does not overlap with the band registered by the antenna in frequency itself and corresponding frequency multiplication, can be found in the first matching list.
In one implementation, the step 102, when obtaining the second communication parameter according to the first communication parameter, may be implemented by:
and searching a second communication parameter which does not meet a second matching condition with the first communication parameter in a second matching list corresponding to the communication terminal.
The second matching list comprises a plurality of candidate communication parameters corresponding to the second component, each candidate communication parameter corresponding to the second component and at least one candidate communication parameter corresponding to the first component meet a second matching condition, and the second matching condition represents that the candidate communication parameters are overlapped on communication frequency. As shown in fig. 5, the second matching list includes a plurality of parameter sets, each parameter set includes one candidate communication parameter corresponding to the second component and at least one candidate communication parameter corresponding to the first component, and the candidate communication parameters in each parameter set satisfy a second matching condition, that is, the candidate communication parameters belonging to two components in each parameter set overlap with each other in communication frequency. Based on this, in this embodiment, after the first communication parameter is obtained, the parameter group that does not correspond to the first communication parameter, that is, the parameter group that does not include the first communication parameter is found in the second matching list, so that the candidate communication parameter corresponding to the second component in the parameter group that does not include the first communication parameter is determined as the second communication parameter.
For example, the first matching list includes 2 parameter sets, parameter set 1 includes a mipi frequency 1 of the LCD driver IC and a band1, a band2, and a band3 of the antenna, mipi frequency 1 and a frequency multiplication thereof and band1, band2, and band3 of the antenna overlap in frequency, parameter set 2 includes a mipi frequency 2 of the LCD driver IC and a band4 and a band5 of the antenna, mipi frequency 2 and a frequency multiplication thereof and a band4 and a band5 of the antenna overlap in frequency, and based on this, after obtaining the band1 registered by the antenna, in this embodiment, after obtaining the band1 registered by the antenna, a mipi frequency that is not in the same parameter set as the band1, that is, mipi frequency 2, that is, a mipi frequency that does not overlap in frequency and frequency multiplication with the band registered by the antenna can be found in the second matching list.
In one implementation manner, before step 103, the following steps are further included in this embodiment, as shown in fig. 6:
step 104: it is determined whether the second communication parameters are obtained, and if the second communication parameters are not obtained, step 105 is performed, and if the second communication parameters are obtained, step 103 is performed.
If the second communication parameter that does not overlap with the first communication parameter in the communication frequency is not obtained, the characterization cannot avoid the interference between the first component and the second component by switching the communication parameter of the second component, that is, no communication parameter can avoid the first communication parameter of the first component, and at this time, the communication quality of the communication terminal can be ensured through step 105.
Step 105: a third component in the communication terminal is controlled to operate in accordance with the first communication parameter in place of the first component.
And the distance between the third component and the second component is larger than the interference resistance value. The third component is a component of the communication terminal for implementing data transmission with other terminals, such as an antenna disposed at the side of the screen, and is different from an antenna disposed at the bottom of the screen. The component distance between the third component and the second component is greater than the interference rejection value, whereby the third component can operate with the first communication parameter without interfering with the second component operating with a communication parameter that overlaps the first communication parameter.
Specifically, in this embodiment, a switch may be disposed between the first component and the third component, and the third component replaces the first component through the switch, so that the third component can implement the operation function of the original first component, such as voice communication.
For example, the third component may be an antenna disposed at the side of the screen, which is different from the antenna disposed at the bottom of the screen, and the distance between the antenna disposed at the side of the screen and the LCD driver IC is relatively high, and if the mipi frequency capable of avoiding the antenna band cannot be found in the process of performing voice communication by using the antenna at the bottom of the screen, the mobile phone may perform voice communication by using the antenna at the side of the screen under the first communication parameter, and at this time, the mobile phone may not be interfered by the communication of the LCD driver IC.
It should be noted that if the communication parameters of the second component are not switched in consideration of the fact that the second component is not currently in the operating state when the second communication parameters are obtained, there may be a case where the second component suddenly enters the operating state, so that the operation of the first component is disturbed. Therefore, in this embodiment, regardless of whether the second component is currently in an operating state, as long as the second communication parameter that does not overlap with the first communication parameter in the communication frequency is found, the second component is switched to operate on the second communication parameter, and if the second communication parameter that does not overlap with the first communication parameter in the communication frequency is not found, the third component is switched to operate, thereby ensuring the communication quality during the operation of the first component or the third component with the first communication parameter.
For example, when the mobile phone performs voice communication with the antenna at the bottom of the screen in the band1, the LCD driver IC at the bottom of the screen is switched to the mipi frequency 2 after finding the mipi frequency 2 which is not overlapped with the band1 in the frequency itself and the corresponding frequency multiplication, regardless of whether the screen is in the bright state and is performing picture output, so that even if the screen is switched from the black state to the bright state, that is, the LCD driver IC starts to receive the picture output of the CPU to the screen in the mipi frequency 2, the communication quality of the voice communication is not affected in the process that the mobile phone performs voice communication with the antenna at the bottom of the screen in the band 1.
In one implementation manner, before step 103, the following steps are further included in this embodiment, as shown in fig. 7:
step 106: and judging whether the second component is in the running state, if so, executing the step 103, and if not, prohibiting executing the step 103, namely ending the current flow.
That is, in this embodiment, the communication interference on the first component caused by the second component entering the running state from the non-running state is not considered, and the second component is switched to run on the second communication parameter only when the second component is in the running state, and if the second component is always in the non-running state, the second component may not cause interference on the communication of the first component, so step 103 may not be executed in this embodiment, that is, the communication parameter of the second component does not need to be switched.
For example, when a mobile phone performs voice communication with the antenna at the bottom of the screen in the band1, if the screen of the mobile phone is bright and picture output is being performed, the LCD driver IC at the bottom of the screen is switched to the mipi frequency 2, so that the LCD driver IC is switched to the mipi frequency 2 in the process of performing voice communication with the antenna at the bottom of the screen in the band1 of the mobile phone, so as to avoid affecting the communication quality of the voice communication, and if the screen of the mobile phone is always black, even if the mipi frequency 2 is obtained, the LCD driver IC is not required to be switched to the mipi frequency 2.
In one implementation manner, before step 103, the following steps are further included in this embodiment, as shown in fig. 8:
step 107: it is determined whether the second component is in an operational state and if the second component is in an operational state, step 108 is performed and if the second component is not in an operational state, step 103 is performed.
Step 108: the third component in the communication terminal is controlled to operate in accordance with the first communication parameter in place of the first component. And the distance between the third component and the second component is larger than the interference resistance value.
That is to say, in this embodiment, it needs to be considered that switching the communication parameter of the second component affects the function of the second component, and if the second component is currently in an operating state, switching the communication parameter of the second component may cause an abnormality to occur in the operation of the second component, such as a screen of a mobile phone being stuck. Therefore, in the present embodiment, in order to ensure normal operation of the second component if the second component is found to be in an operating state, even if the second communication parameter that does not overlap with the first communication parameter is obtained, the communication parameter of the second component is not switched, but in order to ensure the communication quality of the first component, the third component may be controlled to replace the first component for communication, and thus, both the communication instruction and normal operation of the second component may be ensured by the third component.
For example, when a mobile phone performs voice communication with the antenna at the bottom of the screen in the band1, if the screen of the mobile phone is in a bright state and picture output is performed, the LCD driver IC at the bottom of the screen is not switched to the mipi frequency 2, but the antenna at the side of the mobile phone screen replaces the antenna at the bottom of the screen to perform voice communication with the band1, so that the communication quality of the voice communication can be guaranteed, and the abnormal screen output caused by the switching of the mipi frequency by the LCD driver IC can be avoided.

It should be noted that, in the present embodiment, reference may be made to the corresponding contents in the foregoing, and details are not described here.
The technical scheme of the application is described below by taking a mobile phone with an LCD driver IC arranged at the bottom of a screen as an example:
the LCD driver IC is arranged at the bottom of the screen, namely in the setting area of the main antenna of the mobile phone. Based on the method, the application debugs multiple groups of mipi frequencies by modifying a modem algorithm. When the mobile phone registers in a certain band interfered by the mipi, the mipi can be switched to another group of frequencies through an algorithm, so that the current band is completely avoided by the mipi frequency, the normal work of the mobile phone is ensured, and the deterioration of the user communication experience caused by bright screen interference is avoided. For bands where multiple sets of mipi frequencies cannot be avoided, a set of side antennas (which can be co-antenna with other antennas) can be added, and the antennas can be cut to the side to avoid the bottom area, so as to reduce interference. And the user experience is improved. The specific scheme is as follows:
first, in the present application, the LCD mipi frequency is debugged according to the band information supported by the mobile phone, and two sets of mipi values are selected, as shown in fig. 15. The bands are divided into three groups, wherein the two groups can respectively call different mipi frequencies to avoid interference. Band combinations that do not avoid all mipi frequencies are selected and classified into a third group.
Therefore, through the control scheme provided by the application, when the mobile phone registers to a certain band, the mipi frequency is automatically switched to the group of frequencies without interference. If the band registered by the mobile phone is unavoidable for all the selected mipi values, the bottom antenna is switched to the side antenna through the switch. Therefore, interference frequency points are avoided, and user experience is improved.
