The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Example one
Referring to fig. 3, a flowchart of a communication channel setting method provided in a first embodiment of the present invention is shown, where the method is applied to a mobile terminal, and the mobile terminal may include: the mobile terminal is communicated with the base station through the first radio frequency link. The method specifically comprises the following steps:
In the embodiment of the present invention, referring to fig. 4, fig. 4 is a schematic diagram illustrating a mobile terminal communication provided in a first embodiment of the present invention. The mobile terminal 10 may include a first radio frequency link and a second radio frequency link, the mobile terminal 10 may communicate with the base station 50 through the first radio frequency link, and the mobile terminal 10 may receive the first signal of each frequency point through the second radio frequency link. That is, the mobile terminal 10 may receive a signal transmitted by a device such as a base station through the first rf link, or transmit a signal to a device such as a base station through the first rf link, so as to ensure normal operation of the mobile terminal.
In a specific application, a frequency point setting interface for a mobile terminal to receive signals may be called, where a first radio frequency link of the mobile terminal is set to receive signals of all frequency points, and a second radio frequency link of the mobile terminal is set to receive a first signal of a certain frequency point.
In the embodiment of the present invention, the frequency point may be a frequency point supported by the mobile terminal, for example, if the mobile terminal a supports the frequency points of 2135MHZ to 2165MHZ, the frequency points may be frequency points included in 2135MHZ to 2165 MHZ. In the embodiment of the present invention, this is not particularly limited.
In this embodiment of the present invention, the first signal may be a signal of a certain frequency point in signals that can be received by the second radio frequency link of the mobile terminal. The main component of the first signal may be an interference signal, the first signal may further include other signals than the interference signal, and the like. For example, the first signal at the 2135MHZ frequency point is a signal of the 2135MHZ frequency point that can be received by the second radio frequency link of the mobile terminal. The first signal of 2135MHZ frequency point may include an interference signal of 2135MHZ frequency point, and may also include other signals besides the interference signal of 2135MHZ frequency point, etc. In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, referring to fig. 5, fig. 5 shows a schematic diagram of a second radio frequency link provided in the first embodiment of the present invention. The second radio frequency link may include a frequency point setting switch 31, a filtering unit 32 and an amplifying unit 33. The frequency point setting switch 31 is set at that frequency point, and receives the first signal of that frequency point. The first signal may be filtered by the filtering unit 32 and amplified by the amplifying unit 33. In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, the second radio frequency link of the mobile terminal may be set to receive the first signal of a certain frequency point by calling a frequency point setting interface for the mobile terminal to receive the signal, for example, the frequency point setting switch in fig. 5 may be set to receive the first signal of a certain frequency point. For example, for the above example, the second rf link of the mobile terminal a may be sequentially configured to receive the first signals of each frequency point included in 2135MHZ to 2165MHZ, and further sequentially receive the first signals of each frequency point. In the embodiment of the present invention, this is not particularly limited.
In specific application, the maximum frequency point or the minimum frequency point supported by the mobile terminal can be set as a starting frequency point, the minimum frequency point or the maximum frequency point supported by the mobile terminal can be set as an ending frequency point, a certain step length is set, and each frequency point which can be received by the second radio frequency link of the mobile terminal is adjusted in sequence. For example, for the above example, the starting frequency point may be set to 2135MHZ, the ending frequency point may be set to 2165MHZ, the set step size is 10MHZ, and each frequency point that can be received by the second radio frequency link of the mobile terminal is adjusted in sequence.
And 102, determining the signal intensity of the first signal of each frequency point.
In the embodiment of the present invention, the signal strength of the first signal at each frequency point may be determined. For example, for the above example, the signal strength of the 2135MHZ first signal received by mobile terminal a, the signal strength of the 2145MHZ first signal received by mobile terminal a, etc. may be determined, the signal strength of the 255MHZ first signal received by mobile terminal a, etc. may be determined, and the signal strength of the 2165MHZ first signal received by mobile terminal a, etc. may be determined. This is not particularly limited in the embodiments of the present invention.
And 103, determining the target frequency point with the signal intensity smaller than a preset threshold value in the frequency points supported by the mobile terminal.
In the embodiment of the present invention, the preset threshold may be set according to actual communication needs, and the like, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the present invention, a target frequency point with a signal strength smaller than a preset threshold is determined among the frequency points supported by the mobile terminal, that is, a target frequency point with less or no use by the outside is determined among the frequency points supported by the mobile terminal.
For example, for the above example, if the mobile terminal a supports the frequency points from 2135MHZ to 2165MHZ, if the signal strength of the 2145MHZ first signal is less than the preset threshold, the determined target frequency point may be 2145 MHZ. Referring to fig. 6, fig. 6 is a schematic diagram illustrating a target frequency point provided in the first embodiment of the present invention. The frequency point corresponding to M in fig. 6 may be 2145 MHZ. In this case, the 2145MHZ frequency point is used less, or not, by the outside world.
In the embodiment of the present invention, the number of the target frequency points may be 1, or may be multiple. This is not particularly limited in the embodiments of the present invention. For example, for the above example, if the mobile terminal a supports the frequency points from 2135MHZ to 2165MHZ, if the signal strength of the first signal at 2145MHZ is smaller than the preset threshold, and if the signal strength of the first signal at 2135MHZ is also smaller than the preset threshold, the determined target frequency points may be 2145MHZ and 2135 MHZ.
And step 104, setting the communication channel of the mobile terminal as the communication channel corresponding to the target frequency point.
In the embodiment of the invention, the mobile terminal can negotiate with the base station, and then the communication channel of the mobile terminal is set as the communication channel corresponding to the target frequency point. Specifically, the mobile terminal may report the communication channel corresponding to the target frequency point to the base station simultaneously in the process of reporting the communication quality to the base station, and then negotiate with the base station, and set the communication channel of the mobile terminal as the communication channel corresponding to the target frequency point. This is not particularly limited in the embodiments of the present invention.
In the embodiment of the present invention, for the above example, the communication channel of the mobile terminal a may be set as the communication channel corresponding to the target frequency point 2145 MHZ. That is, of the frequency points supported by the mobile terminal a, the 2145MHZ frequency point is used less or not used outside. In the 2135MHZ-2165MHZ frequency points supported by the mobile terminal A, 2145MHZ frequency points are less used or not used by the outside, the communication channel of the mobile terminal A is arranged in the communication channel corresponding to the frequency point 2145MHZ which is less used or not used by the outside, the interference of the first signal of the frequency point 2145MHZ on the mobile terminal is less, and then the influence of the first signal on the work of the mobile terminal can be avoided to a greater extent, and simultaneously, the interference and the influence of the interference signal which is positioned in the communication channel corresponding to the 2145MHZ of the mobile terminal on the mobile terminal are avoided to a certain extent, and the working performance of the mobile terminal is improved.
In the embodiment of the present invention, as shown in fig. 6, if the frequency point of the original communication channel of the mobile terminal is N points, and if the target frequency point whose signal intensity is smaller than the preset threshold value is determined to be M points among the frequency points supported by the mobile terminal, the communication channel of the mobile terminal may be set as the communication channel corresponding to the M points, and the frequency point of the M points is hardly used by the outside, so that the influence of the outside signal on the operation of the mobile terminal can be avoided to a large extent, and the interference and the influence of the interference signal located in the communication channel corresponding to the original frequency point N of the mobile terminal on the mobile terminal are avoided to a certain extent, so as to improve the operation performance of the mobile terminal.
In the embodiment of the present invention, if there are multiple target frequency points, one of the multiple target frequency points may be selected, and a communication channel corresponding to the target frequency point may be set as a communication channel of the mobile terminal. Or, a target frequency point with the minimum signal intensity of the corresponding first signal may be further selected from the multiple target frequency points, and the communication channel corresponding to the target frequency point may be set as the communication channel corresponding to the target frequency point. That is to say, the communication channel corresponding to the target frequency point with the minimum interference is selected as the communication channel of the mobile terminal, so that the interference of the first signal of the frequency point on the mobile terminal can be avoided to the greatest extent, and the working performance of the mobile terminal is improved.
For example, for the above example, if the mobile terminal a supports the frequency points of 2135MHZ to 2165MHZ, if the signal strength of the first signal of 2145MHZ is less than the preset threshold, and if the signal strength of the first signal of 2135MHZ is also less than the preset threshold, the determined target frequency points may be 2145MHZ and 2135MHZ, and in the two target frequency points, the signal strength of the first signal of 2145MHZ is less than the signal strength of the first signal of 2135MHZ, which indicates that the interference of the first signal of 2145MHZ on the mobile terminal is less, and the communication channel of the mobile terminal may be set as the communication channel corresponding to 2145 MHZ. That is to say, the target frequency point with the minimum signal strength of the first signal, that is, the communication channel corresponding to the target frequency point with the minimum interference, is selected as the communication channel of the mobile terminal, so that the interference of the first signal of the frequency point on the mobile terminal can be avoided to the greatest extent, and the working performance of the mobile terminal is improved.
In an embodiment of the present invention, the mobile terminal includes: a first radio frequency link and a second radio frequency link; the mobile terminal communicates with the base station through the first radio frequency link and receives first signals of all frequency points based on the second radio frequency link; each frequency point is a frequency point supported by the mobile terminal; determining the signal intensity of the first signal of each frequency point; determining a target frequency point with the signal intensity smaller than a preset threshold value in the frequency points supported by the mobile terminal; and setting the communication channel of the mobile terminal as the communication channel corresponding to the target frequency point. In each frequency point supported by the mobile terminal, if the signal intensity of a first signal of a certain frequency point received by a second radio frequency link is smaller than a preset threshold value, the frequency point is indicated to be used less or not used by the outside, a communication channel of the mobile terminal is arranged in a communication channel corresponding to the frequency point which is used less or not used by the outside, the interference of the first signal of the frequency point to the mobile terminal is small, further the influence of the first signal on the work of the mobile terminal can be avoided to a large extent, the interference and the influence of an interference signal in the communication channel corresponding to the work frequency point of the mobile terminal to the mobile terminal are avoided to a certain extent, and the working performance of the mobile terminal is improved; and the mobile terminal communicates with the base station through the first radio frequency link, and receives the first signals of each frequency point based on the second radio frequency link, so that the normal work of the mobile terminal is not influenced.
Example two
Referring to fig. 7, a flowchart of a communication channel setting method provided in the second embodiment of the present invention is shown, where the method is applied to a mobile terminal, and the mobile terminal may include: the mobile terminal is communicated with the base station through the first radio frequency link. The method may specifically comprise the steps of:
In this embodiment of the present invention, in this step 201, reference may be made to the related description of the step 101, and it should be noted that, when the mobile terminal is in an idle state, the first signal of each frequency point is received based on the second radio frequency link. That is, the first signal of each frequency point may be received based on the second radio frequency link when the mobile terminal does not perform data interaction with a device such as a base station, and both the first radio frequency link and the second radio frequency link may be used for normal data interaction when the mobile terminal performs data interaction with a device such as a base station, so as to avoid the influence of the above operations on the data interaction of the mobile terminal. For example, when the radio resource control state of the mobile terminal identification card is an idle state, the first signal of each frequency point may be received based on the second radio frequency link. In the embodiment of the present invention, this is not particularly limited.
In an embodiment of the present invention, the mobile terminal may output the second signal. The frequency point of the second signal may be within a preset range from the frequency point of the first signal. The preset range can be set according to actual conditions. For example, if the first signal is cosw1t, then the second signal may be cosw2t, the frequency point of the first signal may be w1The frequency point of the second signal can be w2/2π，w1N 2 and w2If the difference value of/2 pi is within a preset range, then w1And w2The difference in (c) may be within a preset range. For example, if the predetermined range is 3MHZ, | w1/2π-w2The pi/2 is less than or equal to 3 MHZ. In the embodiment of the present invention, w may be determined according to the frequency point of the first signal, and the like2. In the embodiment of the present invention, this is not particularly limited.
Specifically, the mobile terminal may output the second signal through an oscillator of the mobile terminal by controlling a clock signal. The frequency point of the second signal may be within a preset range from the frequency point of the first signal. In the embodiment of the present invention, this is not particularly limited.
And 203, mixing the first signals of each frequency point with the corresponding second signals to obtain low-frequency signals corresponding to each first signal.
In the embodiment of the present invention, the difference between the frequency point of the second signal and the frequency point of the first signal is within a preset range, and the preset range may be set according to an actual situation. And mixing the first signal of each frequency point with the corresponding second signal, that is, mixing the first signal of each frequency point with the second signal corresponding to the first signal frequency point, where the mixing may be to perform corresponding calculation and the like on the first signal of each frequency point and the second signal corresponding to the first signal frequency point, so as to obtain the low-frequency signal corresponding to each first signal. The mobile terminal may include a mixing unit, and the like, and may mix the first signal of each frequency point with the second signal corresponding thereto. In the embodiment of the present invention, this is not particularly limited.
For example, for the above example, w may be1First signal cosw of/2 pi frequency point1t and a second signal cosw output by the mobile terminal2t, performing corresponding frequency mixing calculation and the like to obtain w1The low-frequency signal corresponding to the first signal of the/2 pi frequency point can obtain the frequency point w1/2π-w2Cos of/2 π (w 1-w)2)t。|w1/2π-w2The/2 pi | is within a preset range. The mixing may be a superposition of the first signal and a second signal corresponding to the first signal frequency point, or the like. In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, the signal strength of the low frequency signal corresponding to each first signal may be determined, for example, for the above example, if the received frequency point is w1First signal cosw of/2 pi1t, if the second signal frequency point corresponding to the first signal frequency point generated by the mobile terminal is the frequency point w2Second signal cosw of/2 pi2t，|w1/2π-w2The first signal and the second signal corresponding to the frequency point of the first signal are mixed within a preset range to obtain the frequency point w1The frequency point of the low-frequency signal corresponding to the first signal of/2 pi is w1/2π-w2Cos of/2 π (w 1-w)2) t, the calculated frequency point is w1The frequency point of the low-frequency signal corresponding to the first signal of/2 pi is w1/2π-w2Cos of/2 π (w 1-w)2) t, signal strength. In the embodiment of the invention, the calculation frequency point is w1The frequency point of the low-frequency signal corresponding to the first signal of/2 pi is w1/2π-w2Cos of/2 π (w 1-w)2) t, signal strength. For example, the signal strength may be determined in terms of signal power or signal energy, etc., which may characterize the signal strength. E.g., can adopt
Calculating the frequency point as w1/2π-w2Cos of/2 π (w 1-w)2) T may be a period of the low frequency signal corresponding to the first signal, where T is 2 pi/(w)1/2π-w2And/2 pi). In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, the signal strength of the first signal of each frequency point is determined based on the signal strength of the low-frequency signal corresponding to each first signal. Specifically, the signal strength of the low-frequency signal corresponding to each first signal may reflect the signal strength of the first signal of each frequency point to a certain extent, and the signal strength of the low-frequency signal corresponding to each first signal may be determined as the signal strength of the first signal of each frequency point, or the signal strength of the low-frequency signal corresponding to each first signal may be determined as the signal strength of the first signal of each frequency point by performing correlation calculation corresponding to the mixing. In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, the signal strength of the second signal corresponding to the first signal, which is usually generated by the mobile terminal, may be determined during the generation process of the mobile terminal, and the signal strength of the low-frequency signal of a certain frequency point is obtained by mixing or superimposing the first signal and the second signal corresponding to the first signal frequency point, and the signal strength of the low-frequency signal of a certain frequency point and the signal strength of the second signal may be inversely superimposed, that is, the signal strength of the first signal of the frequency point may be obtained. For example, for the above example, the mobile terminal generates a frequency point of w2Second signal cosw of/2 pi2the signal intensity of t can be determined in the process of generating the mobile terminal, and the frequency point obtained by calculation is w1/2π-w2Low frequency signal cos of/2 pi (w 1-w)2) t, and then the corresponding reverse superposition is carried out to obtain the frequency point w1First signal cosw of/2 pi1t, signal strength. In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, referring to fig. 8, fig. 8 is a schematic diagram illustrating the determination of the signal strength of the first signal according to the second embodiment of the present invention. And controlling a frequency point setting switch 31 of a second radio frequency link of the mobile terminal, setting the frequency point setting switch 31 at a corresponding frequency point, receiving a first signal of the corresponding frequency point, filtering the first signal by a filtering unit 32, amplifying the first signal by an amplifying unit 33, and the like. And controlling a baseband chip 37 of the mobile terminal, wherein the baseband chip 37 controls a corresponding clock unit 35, controls an oscillator 34 to output a second signal corresponding to the first signal, controls the second signal, inputs the filtered and amplified first signal into a corresponding mixing unit 36, and performs mixing to obtain a low-frequency signal corresponding to the first signal of the frequency point, and determines the signal intensity of the first signal of the frequency point through the baseband chip 37, and so on, and determines the signal intensity of the first signal of each frequency point. In the embodiment of the present invention, this is not particularly limited.
In the embodiment of the present invention, the signal strength of the first signal of each frequency point is determined based on the signal strength of the low-frequency signal corresponding to each first signal. In the process of calculating the signal intensity of the low-frequency signal corresponding to the first signal, the calculated amount is relatively small, so that the working efficiency can be improved, and the speed of determining the signal intensity of the first signal of each frequency point is increased.
In the embodiment of the present invention, the first signal of each frequency point and the signal strength of the first signal may be stored correspondingly. In the embodiment of the present invention, this is not particularly limited.
And step 207, setting the communication channel of the mobile terminal as the communication channel corresponding to the target frequency point.
