However, for broadband communication with a wide bandwidth, such as Long Term Evolution (LTE), the existing requirements cannot be met between cells. For example, for GSM, the interference frequency point can be removed by clock signal hopping by 2M, but to remove the LTE interference frequency point, wideband hopping is required, for example, hopping of 15M or higher band. The jumping of the wide frequency band can cause the frame rate of the display screen to change, and particularly at the jumping moment, the display screen is difficult to repair temporarily.
Therefore, a new technical solution is needed to solve the above technical problems.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, a schematic flowchart of an implementation flow of a frequency hopping method of a clock signal provided in an embodiment of the present application, where the frequency hopping method is applied to a mobile terminal, and as shown in the drawing, the frequency hopping method may include the following steps:
step S101, when the first frequency of a clock signal of a display screen of a mobile terminal is jumped to the target frequency of the clock signal, acquiring the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal.
In the embodiment of the present application, the transfer of the interference frequency point may be realized by hopping two frequencies of a clock signal of a display screen, for example, if a first frequency of the clock signal is a, a target frequency of the clock signal is B, and a has interference on the channel 1, then the interference on the channel 1 may be eliminated by hopping a to B. Similarly, B interferes with channel 2, and then B can be hopped to a to cancel the interference on channel 2, where B is the first frequency of the clock signal and a is the target frequency of the clock signal.
Step S102, dividing a bandwidth between a first frequency of the clock signal and a target frequency of the clock signal into N segments, where N is an integer greater than 1.
For broadband communication (e.g. LTE), since the bandwidth is wide, directly jumping the first frequency of the clock signal to the target frequency of the clock signal may affect repair or recovery of the frame rate of the display screen, and in order to avoid the influence of frequency jumping on the display screen, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal may be divided into N segments, so as to ensure that a narrower bandwidth exists between adjacent frequency points. For example, the first frequency of the clock signal is 514.5MHz, the target frequency of the clock signal is 529MHz, the bandwidth between 514.5MHz and 529MHz is divided into four sections, the first section is 514.5MHz to 517.5MHz, the second section is 517.5MHz to 520.5MHz, the third section is 520.5MHz to 525.5MHz, and the fourth section is 525.5MHz to 529 MHz.
And step S103, jumping the first frequency of the clock signal to the target frequency of the clock signal after N times of jumping according to the divided N sections of bandwidths.
In the embodiment of the application, after the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal is divided into N sections, the bandwidth of each jump of the frequency of the clock signal can be reduced, so that the jump of a wide frequency band is realized through multiple step jumps. The step jumping can be realized by climbing stairs for multiple times.
In this embodiment of the application, a user may set the value of N by himself, or the system sets the value of N in advance, or the mobile terminal sets the value of N according to the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal and the requirement of each segment of bandwidth after segmentation, which is not limited herein. For example, if the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal is 30MHz, and it is required that the bandwidth of each segment after segmentation does not exceed 8MHz, N may be set to 5 or greater than 5.
According to the embodiment of the application, the first frequency of the clock signal is subjected to N-order jump to the target frequency of the clock signal, so that the jump of the broadband can be realized, and the frequency band of each jump is narrowed, so that the frame rate of the display screen can be repaired while the jump of the broadband is realized.
Referring to fig. 2, it is a schematic diagram of an implementation flow of a frequency hopping method of a clock signal provided in the second embodiment of the present application, where the frequency hopping method is applied to a mobile terminal, and as shown in the figure, the frequency hopping method may include the following steps:
step S201, when the first frequency of the clock signal of the display screen of the mobile terminal is jumped to the target frequency of the clock signal, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal is obtained.
In the embodiment of the present application, the transfer of the interference frequency point may be realized by hopping two frequencies of a clock signal of a display screen, for example, if a first frequency of the clock signal is a, a target frequency of the clock signal is B, and a has interference on the channel 1, then the interference on the channel 1 may be eliminated by hopping a to B. Similarly, B interferes with channel 2, and then B can be hopped to a to cancel the interference on channel 2, where B is the first frequency of the clock signal and a is the target frequency of the clock signal.
Optionally, the embodiment of the present application further includes:
the mobile terminal uses a Long Term Evolution (LTE) network;
a bandwidth between a first frequency of the clock signal and a target frequency of the clock signal exceeds a maximum of an LTE bandwidth.
In the embodiment of the application, since the bandwidth of the LTE frequency band is wide, in order to avoid a frequency point which causes interference to LTE between the first frequency of the clock signal and the target frequency of the clock signal, when the first frequency of the clock signal and the target frequency of the clock signal are set, it is to be ensured that the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal exceeds the maximum value of the LTE bandwidth. Since the LTE common bandwidth is 1.4MHz, 2.5MHz, 5MHz, 10MHz, 15MHz, and 20MHz, respectively, the maximum value of the LTE bandwidth may be 20 MHz.
Step S202, dividing a bandwidth between a first frequency of the clock signal and a target frequency of the clock signal into N segments, where N is an integer greater than 1.
For broadband communication (e.g. LTE), because the bandwidth is wide, directly jumping the first frequency of the clock signal to the target frequency of the clock signal may affect the repair of the frame rate of the display screen, and in order to avoid the influence of the frequency jump on the display screen, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal may be divided into N segments, so as to ensure that a narrower bandwidth exists between adjacent frequency points. For example, the first frequency of the clock signal is 514.5MHz, the target frequency of the clock signal is 529MHz, the bandwidth between 514.5MHz and 529MHz is divided into four sections, the first section is 514.5MHz to 517.5MHz, the second section is 517.5MHz to 520.5MHz, the third section is 520.5MHz to 525.5MHz, the fourth section is 525.5MHz to 529MHz, 514.5MHz, 517.5MHz, 520.5MHz, 525.5MHz and 529MHz can respectively correspond to one frequency point, and according to the sequence from the first frequency of the clock signal to the target frequency of the clock signal, the first frequency point is assigned to 514.5MHz, the second frequency point is assigned to 517.5MHz, the third frequency point is assigned to 520.5MHz, the fourth frequency point is assigned to 525.5MHz, and the fifth frequency point is assigned to 529 MHz.
Optionally, the dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments includes:
the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal is evenly divided into N segments.
In the embodiment of the present application, the bandwidth between the first frequency a of the clock signal and the target frequency B of the clock signal may be equally divided into N segments, each segment has the same bandwidth, as shown in fig. 3a, the bandwidth between the first frequency a of the clock signal and the target frequency B of the clock signal is divided into four segments, each segment has a bandwidth of 6MHz, B1 is the second frequency, B2 is the third frequency, B3 is the fourth frequency, t is the total time for jumping the first frequency to the target frequency, t1 is the time for jumping the first frequency a to the second frequency B1, t2 is the time for jumping the second frequency B1 to the third frequency B2, t3 is the time for jumping the third frequency B2 to the fourth frequency B3, t4 is the time for jumping the fourth frequency B3 to the target frequency B, and t is the sum of t1, t2, t3 and t 4.
Optionally, the dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments includes:
the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal is unequally divided into N segments.
In the embodiment of the present application, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal may be divided into N sections on a non-average basis, the bandwidth of the N sections is not completely the same (for example, when the sections are divided into sections from the first frequency of the clock signal, the bandwidth of each section is sequentially increased by 1MHz), as shown in fig. 3B, the bandwidth 22MHz between the first frequency a of the clock signal and the target frequency B of the clock signal is divided into four sections, the bandwidth between a and B1 is 4MHz, the bandwidth between B1 and B2 is 5MHz, the bandwidth between B2 and B3 is 6MHz, the bandwidth between B3 and B is 7MHz, B1 is the second frequency, B2 is the third frequency, B3 is the fourth frequency, t is the total time for jumping the first frequency to the target frequency, t1 is the time for jumping the first frequency a to the second frequency B1, t2 is the time for jumping the second frequency B1 to the third frequency B2, t3 is the third frequency B3638 to the fourth frequency B2, t4 is the time to jump the fourth frequency B3 to the target frequency B, t being the sum of t1, t2, t3 and t 4.
Step S203, jumping the first frequency of the clock signal to the second frequency of the clock signal.
The N sections of bandwidths correspond to N +1 frequency points, the first frequency point corresponds to the first frequency of the clock signal, the second frequency point corresponds to the second frequency of the clock signal, and by analogy, the N +1 frequency point corresponds to the target frequency of the clock signal;
step S204, jumping the second frequency of the clock signal to a third frequency of the clock signal.
And step S205, and so on, until the Nth frequency of the clock signal is jumped to the target frequency of the clock signal.
For example, when the first frequency 514.5MHz of the clock signal is hopped to the target frequency 529MHz of the clock signal after four step jumps, 514.5MHz may be hopped to 517.5MHz first, 517.5MHz may be hopped to 520.5MHz, 520.5MHz may be hopped to 525.5MHz, and 525.5MHz may be hopped to 529MHz finally, since the bandwidth at each jump is narrow (for example, less than 20M is made to be narrow bandwidth), the influence on the display screen may be effectively avoided.
Optionally, the embodiment of the present application further includes:
the time of each jump of the frequency of the clock signal does not exceed the frame rate repair time of the display screen, wherein the frame rate repair time of the display screen refers to the time for repairing the self display effect after the frequency of the clock signal of the display screen is changed.
In the embodiment of the application, the time of each jump of the frequency of the clock signal is controlled not to exceed the frame rate recovery time of the display screen, so that the display of the display screen is not influenced during each jump, and the frame rate of the display screen is repaired. As shown in fig. 3a, t1, t2, t3 and t4 do not exceed the frame rate repair time of the display screen.
Optionally, the embodiment of the present application further includes:
and the total time of jumping to the target frequency of the clock signal after the first frequency of the clock signal is subjected to N times of jumping is less than the communication establishment time, wherein the communication establishment time refers to the time of establishing communication connection between the base station and the mobile terminal.
In the embodiment of the present application, by controlling the total time (t in fig. 3 a) taken for the first frequency of the clock signal to jump to the target frequency of the clock signal after N hops is less than the time for establishing communication, it can be ensured that there is no interference after the communication is switched (for example, the communication connection is re-established between the base station and the mobile terminal when the communication is switched from one channel to another channel).
According to the embodiment of the application, the first frequency of the clock signal is subjected to N-order jump to the target frequency of the clock signal, so that the jump of the broadband can be realized, and the frequency band of each jump is narrowed, so that the frame rate of the display screen can be repaired while the jump of the broadband is realized.
