Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
For convenience of understanding, terms referred to in the embodiments of the present application are explained below.
Harmonic waves: the periodic non-sinusoidal electric quantity signal can be decomposed into a plurality of or infinite linear combinations of sinusoidal signals through Fourier transform, wherein in the sinusoidal signals, the frequency of the sinusoidal signals is the same as the original signal period and is called fundamental wave, and the frequency of the rest sinusoidal signals is integral multiple of the fundamental wave frequency and is called harmonic wave. Harmonics in this application refer to the harmonics of each order generated by the components in the terminal when operating at the available operating frequencies.
In one illustrative example, the screen assembly within the terminal is currently operating at an operating frequency of 100MHz, then 100MHz is the fundamental frequency, and the harmonics generated when the screen assembly is operating at this operating frequency include: the second harmonic having a frequency twice the fundamental frequency (frequency of 200MHz), the third harmonic having a frequency three times the fundamental frequency (frequency of 300MHz), to the nth harmonic having a frequency n times the fundamental frequency (frequency of 100 xnmhz).
Referring to fig. 1, a flowchart of a terminal communication method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
Generally, a signal receiver is provided in a terminal for receiving a signal of the terminal. In the signal receiving process, the signal receiving power of the terminal is changed under the influence of various factors, wherein the larger the signal receiving power is, the higher the signal strength is, the terminal is in a strong signal state, and conversely, the smaller the signal receiving power is, the lower the signal strength is, the terminal is in a weak signal state.
In the embodiment of the application, the terminal measures the signal receiving power in real time in the communication process, so that the signal state of the terminal is determined according to the signal receiving power.
And step 102, if the signal receiving power is smaller than the power threshold, acquiring a current influence channel corresponding to the target component in the terminal under the current working frequency.
In a possible implementation manner, the terminal detects whether the obtained signal receiving power is smaller than a power threshold, and if so, the terminal is determined to be in a weak signal state; and if so, determining that the terminal is in a strong signal state. Wherein, the power threshold is larger than the receiving sensitivity of the terminal (i.e. the minimum signal receiving power allowed under the condition of meeting a certain bit error rate requirement). For example, the terminal has a receive sensitivity of-100 dBm and the power threshold is-70 dBm.
Optionally, in order to improve the detection accuracy, when the signal received power acquired n times is smaller than the power threshold, the terminal determines that the terminal is in a weak signal state. For example, n is 10.
In the operation process of the terminal, each component in the terminal operates under respective available working frequency, harmonic waves generated in the operation of the components can affect signal receiving, and particularly, under the weak signal state, the harmonic waves have obvious effect on the signal receiving.
In order to reduce the influence of harmonic waves on signal reception in a weak signal state, the terminal acquires a current influence channel corresponding to the target component at a current working frequency, wherein the current influence channel comprises channels influenced by each sub-harmonic wave corresponding to the current working frequency.
Optionally, the number of the target components is at least one, and the current affected channel corresponding to the current operating frequency is at least one.
In a possible embodiment, the target component is preset with a plurality of switchable available operating frequencies, wherein each subharmonic of the available operating frequencies may fall within a frequency band of a communication channel of the terminal, and affect the signal reception of the terminal, and a respective affecting channel is preset for each available operating frequency of the target component, and the current affecting channel is the preset affecting channel.
In one illustrative example, the target component currently operates at a frequency of 20 MHz. The current signal receiving power of the terminal is-80 dBm, when the signal receiving power is detected to be smaller than a power threshold value of-70 dBm, the terminal is determined to be in a weak signal state, and a current influence channel corresponding to the target component under the current working frequency of 20MHz is obtained, wherein the current influence channel comprises: channel 1, channel 2, and channel 3. And 103, acquiring the current communication channel of the terminal.
In order to determine whether the harmonic generated when the target component operates will affect the signal reception, the terminal further acquires the current communication channel, so as to subsequently detect whether the current communication channel belongs to the current affected channel corresponding to the target component.
It should be noted that there is no strict time sequence between step 102 and step 103, that is, step 102 and step 103 may be executed synchronously, and this embodiment only uses the example that step 102 is executed before step 103 to perform the schematic description, but does not limit this.
And step 104, if the current communication channel belongs to the current influence channel, determining the target working frequency of the target component.
In a possible implementation manner, a terminal detects whether a current communication channel belongs to a current influence channel, if so, determines that the current communication channel is influenced by harmonic waves generated when a target component operates, and if the target component continues to operate at the current operating frequency, the current communication channel is continuously influenced, so that the operating frequency of the target component is determined to be adjusted; and if not, determining that the harmonic waves generated by the target component in operation do not influence the current communication channel, and keeping the current working frequency of the target component.
In this case, the target component needs to be switched to a target operating frequency suitable for operating in the current communication channel, the target operating frequency belongs to a plurality of switchable available operating frequencies preset by the target component, the set of channels affected by each subharmonic corresponding to the target operating frequency is a target affected channel, and the current communication channel does not belong to the target affected channel corresponding to the target operating frequency.
In an illustrative example, the terminal determines that the terminal is in a weak signal state and the current communication channel is channel 1, the current operating frequency of the target component is 20MHz, and the current affected channel includes channel 1, channel 2, and channel 3, in which case the target component needs to be switched to the target operating frequency suitable for operating in the current communication channel since the current communication channel is included in the current affected channel. The target component has 25MHz and 40MHz of available working frequency besides the current working frequency, the influence channels corresponding to the 25MHz of available working frequency are channel 2 and channel 3, and the influence channels corresponding to the 40MHz of available working frequency are channel 1, channel 3 and channel 4. And determining the available working frequency 25MHz as the target working frequency because the current communication channel does not belong to the influence channel corresponding to the available working frequency 25 MHz.
And 105, switching the target component to the target working frequency.
Further, the terminal switches the target component to the target working frequency, so that harmonic waves generated when the target component operates at the target working frequency cannot affect the current communication channel, and the communication quality of the terminal in a weak signal state is improved.
In summary, in the embodiment of the present disclosure, in the terminal communication process, when the signal receiving power is smaller than the power threshold, it is determined whether the current communication channel of the terminal belongs to the current impact channel corresponding to the target component at the current operating frequency, and when the current communication channel belongs to the current impact channel, the target component is switched to the target operating frequency; because the current communication channel of the terminal does not belong to the target influence channel corresponding to the target working frequency, after the working frequency of the target component is switched, harmonic waves generated when the target component works cannot interfere with the current communication channel of the terminal, so that the influence of the harmonic waves generated by the target component on signal receiving is reduced, and the communication quality in a weak signal state is improved.
In a possible implementation manner, before obtaining the signal receiving power of the terminal, the method further includes a step of generating a channel blacklist of the candidate component, and a subsequent terminal obtains an affected channel corresponding to its operating frequency from the channel blacklist corresponding to the candidate component. The channel blacklist includes influence channels corresponding to all available operating frequencies of the candidate components, and the channel blacklist is generated by the terminal or is written in advance before the terminal leaves a factory. The following description will take an example in which the channel black list is generated by the terminal.
In a possible implementation manner, for each candidate component in the terminal, the terminal obtains an available operating frequency of the candidate component, and determines an influence channel of each subharmonic corresponding to each available operating frequency, so as to generate a channel blacklist corresponding to each available operating frequency according to the influence channel.
In one illustrative example, the candidate component is a screen component, and the screen component is preset with three available operating frequencies, and each available operating frequency and each affected channel of the screen component are shown in table one. The influence channels corresponding to the available working frequency of 20MHz are channel 1, channel 2 and channel 3, the influence channels corresponding to the available working frequency of 25MHz are channel 2 and channel 3, and the influence channels corresponding to the available working frequency of 40MHz are channel 1, channel 3 and channel 4. In this embodiment, the current impact channel and the target impact channel of the target component are obtained from a pre-generated channel blacklist.
Watch 1
Since there are many higher harmonics corresponding to the available operating frequency and the higher harmonics that intersect with the communication channel supported by the terminal may affect the terminal communication, in order to reduce the data amount of the channel blacklist, in one possible implementation, the terminal determines the frequency range of the higher harmonics according to the frequency band of its own available communication channel, so as to add the affected channel corresponding to the higher harmonics in the frequency range to the channel blacklist.
In an illustrative example, the channel frequency band of the available communication channels supported by the terminal is between 900MHz and 1800MHz, the available operating frequency of the candidate component is 20MHz, and the terminal adds the affected channels corresponding to the 45 th to 90 th harmonics to the channel black list.
Referring to fig. 2, a flowchart of a terminal communication method according to another exemplary embodiment of the present application is shown. The method comprises the following steps:
The step 101 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
In step 202, if the signal received power is smaller than the power threshold, the component status of each candidate component is obtained.
The candidate device refers to a device that generates harmonic waves when operating, and the candidate device may include a screen, a camera, a memory, and the like. The embodiment of the present application does not limit the type and number of candidate components in the terminal.
The component states of the candidate component include an active state and an idle state. When the component state of the candidate component is the working state, the candidate component runs at a specific working frequency, so that harmonic waves are generated in the running process of the candidate component, and the generated harmonic waves may affect the current communication channel; when the component state of the candidate component is the idle state, since the candidate component does not operate at the specific operating frequency, it does not generate harmonics, and further does not affect the current communication channel.
And step 203, determining the candidate component in the working state as the target component.
When the signal received power is smaller than the power threshold, the current communication channel of the terminal may be affected by the candidate component in the operating state, so that the candidate component in the operating state needs to be determined as the target component, and further, the operating frequency of the target component is switched.
In one illustrative example, the candidate components within the terminal include a camera component, a screen component, an audio component, and the like. When the terminal opens the camera shooting function, the camera shooting assembly and the screen assembly are in working states, and the camera shooting assembly and the screen assembly are determined to be target assemblies.
And 204, acquiring a current influence channel corresponding to the target component under the current working frequency.
In a possible implementation manner, the target component is preset with a plurality of switchable available operating frequencies, different available operating frequencies correspond to respective influence channels, and when the terminal is in a weak signal state, in order to determine whether a harmonic of the current operating frequency of the target component affects a current communication channel, the current influence channel corresponding to the target component at the current operating frequency needs to be acquired.
In an illustrative example, as shown in table one, the screen component (i.e. the target component) is preset with three switchable available operating frequencies, 20MHz, 25MHz and 40MHz respectively, and each available operating frequency corresponds to a respective affected channel, where 20MHz is the current operating frequency, so that the terminal determines channel 1, channel 2 and channel 3 as the current affected channel.
The step 103 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
In step 206, if the current communication channel belongs to the current affected channel, the candidate working frequency corresponding to the target component is obtained.
In one possible implementation, the target component is preset with a plurality of switchable available operating frequencies, and the affected channels corresponding to the plurality of available operating frequencies are different, wherein the candidate operating frequency refers to an available operating frequency other than the current operating frequency. If the current communication channel belongs to the current influence channel, a suitable candidate working frequency needs to be selected from the candidate working frequencies, so that the harmonic waves generated under the suitable candidate working frequency can not influence the current communication channel.
In an illustrative example, as shown in table one, the screen component (i.e. the target component) is preset with three switchable available operating frequencies, namely 20MHz, 25MHz and 40MHz, wherein 20MHz is the current operating frequency, and the candidate operating frequencies are available operating frequencies other than 20MHz, namely 25MHz and 40 MHz.
Optionally, for each candidate working frequency, the terminal obtains a candidate impact channel corresponding to the candidate working frequency, and detects whether a channel intersection exists between the candidate impact channel and the current communication channel.
If the candidate impact channel comprises the current communication channel (namely, a channel intersection exists between the candidate impact channel and the current communication channel), it is indicated that each harmonic of the candidate working frequency still influences the current communication channel; if the candidate affected channel does not include the current communication channel (i.e., there is no channel intersection between the candidate affected channel and the current communication channel), it indicates that each harmonic of the candidate operating frequency does not affect the current communication channel, and thus the candidate operating frequency is determined as the target operating frequency.
In one illustrative example, as shown in table one, 25MHz and 40MHz are candidate operating frequencies, where the candidate affected channel corresponding to the candidate operating frequency of 40MHz has an intersection with channel 1 (i.e., the current communication channel), and the candidate affected channel corresponding to the candidate operating frequency of 25MHz has no intersection with channel 1, so that the candidate operating frequency of 25MHz is determined as the target operating frequency.
And step 208, switching the target component to the target working frequency.
In a possible implementation manner, when at least two target operating frequencies are determined, the terminal switches the target component to any one of the at least two target operating frequencies.
In order to avoid that the operating state of the target component is greatly influenced due to the overlarge change amplitude of the operating frequency when the operating frequency of the target component is switched, in one possible implementation mode, when at least two target operating frequencies are determined, the target component is switched to the operating frequency which is closest to the current operating frequency in the at least two target operating frequencies.
In an illustrative example, the target component is a screen component, the screen component is preset with four available operating frequencies, and each available operating frequency and each affected channel of the screen component are shown in table two. The current communication channel is channel 1, the current working frequency is 20MHz, and the terminal determines that the target working frequency is 25MHz and 50 MHz. When the working frequency of the screen component is switched, the terminal switches the working frequency of the screen component from 20MHz to 25 MHz.
Watch two
In this embodiment, in a communication process of the terminal, when the signal receiving power is less than the power threshold, the candidate component in the working state is determined as the target component, and when the current communication channel belongs to the current influence channel of the target component, the candidate operating frequency corresponding to the target component is obtained, the target operating frequency is determined according to the candidate influence channel corresponding to the candidate operating frequency, and when at least two target operating frequencies are determined, the target component is switched to the operating frequency closest to the current operating frequency among the at least two target operating frequencies by the terminal.
In the foregoing embodiment, the problem that the signal received power is smaller than the power threshold is solved by switching the available operating frequency of the target component, however, in a possible case, when the candidate impact channels corresponding to the candidate operating frequencies of the target component all intersect with the current communication channel, that is, when the target operating frequency does not exist, the terminal may use the communication channel switching manner, on the basis of fig. 2, as shown in fig. 3, after step 205, the following step may also be included.
In one possible embodiment, the terminal is preset with a plurality of switchable available communication channels, wherein the candidate communication channel refers to an available communication channel other than the current communication channel. In the terminal communication process, if the signal receiving power is smaller than the power threshold and the target operating frequency does not exist, a suitable candidate communication channel needs to be acquired from a plurality of available communication channels, so that the terminal is not affected by the harmonic waves generated when the target component operates under the suitable candidate communication channel.
In an illustrative example, as shown in table three, the camera assembly (i.e., the target assembly) is preset with three switchable available operating frequencies, which are 30MHz, 35MHz and 50MHz, respectively, where 30MHz is the current operating frequency. As can be seen from table three, since the affected channel of each available operating frequency includes channel 1 (current communication channel), the camera module does not have a target operating frequency for switching, and at this time, the terminal acquires a candidate communication channel. The terminal is preset with four available communication channels, namely a channel 1, a channel 2, a channel 3 and a channel 4, and the candidate communication channels are available communication channels except the channel 1, namely the communication channel 2, the communication channel 3 and the communication channel 4.
Watch III
In one possible implementation, for each candidate communication channel, the terminal detects whether the candidate communication channel belongs to the current affected channel of the target component, and if so, the candidate communication channel cannot be determined as the target communication channel; and if not, determining the candidate communication channel as the target communication channel.
Optionally, in order to further improve the communication quality and avoid switching the terminal to a busy communication channel subsequently, the terminal will satisfy the above condition, and the idle candidate communication channel is determined as the target communication channel.
If the candidate communication channel is included in the current affected channel, when the terminal operates in the candidate communication channel, each subharmonic of the current operating frequency still affects the candidate communication channel, so that when the candidate communication channel is determined, the candidate communication channel having no channel intersection with the current communication channel needs to be obtained, and the candidate communication channel having no channel intersection with the current communication channel needs to be determined as the target communication channel, that is, the target communication channel does not belong to the current affected channel, and the target communication channel is an idle channel.
In an illustrative example, the terminal determines communication channels 3 and 4 as target communication channels since communication channels 3 and 4 do not belong to the current affected channel corresponding to 30MHz (i.e., the current operating frequency).
Because the target communication channel does not belong to the current influence channel of the target component, after the terminal is switched to the target communication channel, harmonic waves generated when the target component works do not influence the communication of the terminal.
In a possible implementation manner, when at least two target communication channels are determined, the terminal switches the current communication channel to any one of the at least two target communication channels.
In order to avoid that when the communication channel of the terminal is switched, the communication state of the terminal is greatly influenced due to the fact that the frequency range change amplitude of the communication channel is too large, in a possible implementation mode, when at least two target communication channels are determined, the terminal is switched to the communication channel which is closest to the current communication channel in the at least two target communication channels.
In connection with the example in the above step, the terminal determines the communication channel 3 and the communication channel 4 as the target communication channel. The frequency band of the communication channel 1 (i.e. the current communication channel) is 900MHz, and the frequency bands of the communication channel 3 and the communication channel 4 are 1200MHz and 1800MHz, respectively. When the communication channel of the terminal is switched, the terminal switches the communication channel from 1 to 3.
It should be noted that, except for separately adjusting the operating frequency of the target component and the communication channel of the terminal, the terminal may also simultaneously adjust the operating frequency of the target component and the communication channel of the terminal, so that the harmonic generated when the target component operates does not affect the communication channel of the terminal, and this embodiment is not described herein again.
In this embodiment, in the terminal communication process, when the problem that the signal receiving power is smaller than the power threshold cannot be solved by switching the available operating frequency of the target component, the terminal may solve the problem by switching the communication channel, and when at least two target communication channels are determined, the terminal is switched to the communication channel closest to the current communication channel of the at least two target communication channels, so as to avoid a large influence on the communication state of the terminal due to an excessively large frequency band variation amplitude of the communication channel; after the terminal is switched to the target communication channel, harmonic waves generated when the target assembly works cannot interfere with the target communication channel, so that the influence of the harmonic waves generated by the target assembly on signal receiving is reduced, and the communication quality in a weak signal state is improved.
It should be noted that, in the foregoing embodiment, the communication channel of the terminal is only adjusted when the target operating frequency does not exist, and in other possible embodiments, the terminal may directly adjust the communication channel of the terminal after the current communication channel belongs to the current affected channel, which is not limited in this embodiment of the present application.
