Cell is communicated, each base station is equipped with the antenna in multiple multidirectional antennas or directional property direction, and the signal emitted on antenna can
With the corresponding coverage of coverage base station, each coverage can be covered by one or more than one antenna.The electricity such as mobile phone
Sub-device online or used communication frequency of conversing come from base station, and different base station has different communication frequencies.Base station connects
The signal of communication that sends from mobile terminal is received, base station is by the communication signal transmissions received to base station controller, then by base station
Communication signal transmissions to mobile switching centre are carried out signal exchange by controller, to realize that current mobile terminal user surfs the Internet
Or the communication connection between other network users.
In the cellular system, each region is all divided into several communication cells, and each communication cell distributes different channel sets,
To realize channeling.In communication process, signal is transmitted by way of carrier wave, and the frequency of the data generally sent is low
Frequency, if transmitted according to the frequency of the data of itself, be unfavorable for receive with it is synchronous.Using carrier-wave transmission, we can be incited somebody to action
In the signal loading of data to the signal of carrier wave, recipient receives data-signal, significant signal according to the frequency of carrier wave
The wave amplitude of wave and the wave amplitude of meaningless signal are different, and are out exactly the data letter that we need by these signal extractions
Number.Specific carrier wave is emitted again by antenna in all signal modulations a to special frequency channel, i.e., this frequency range is carrier wave.
Such as in 3G system, due to using CDMA, a frequency point can be multiplexed by many sectors, communication cell, a base
A carrier wave or several carrier waves can be formed by standing etc..

In the embodiment of the present application, the MIPI full name in English in MIPI frequency is Mobile Industry Processor
Interface, Chinese name are mobile industry processor interface.MIPI frequency can be true after the electric circuit diagram design sizing of equipment
It is fixed, the MIPI frequency can be read in the memory of equipment, also can receive MIPI frequency input by user.Different function
Energy module has different MIPI frequencies, such as display screen and camera all have respective MIPI frequency.
Step 102: judging whether Current communications frequency is preset mode.
Specifically, different electronic devices are provided with different functions, therefore used communication frequency is also different.Step 102
The preset mode of middle Current communications frequency includes 4G communication or 3G communication.It should be understood that the electronic devices such as mobile phone online or
Person converses used communication frequency from base station, and different base station has different communication frequencies, such as when electronic device is surfed the Internet
Shi Caiyong 4G mode uses 3G 2G mode when making a phone call.When the mould that the communication frequency of electronic device is 4G or 3G
Formula is preset mode, and 2G is not then preset mode.
Step 103: if so, further judging main carrier whether in the first communication cell.
Current communications frequency includes corresponding main carrier and secondary carrier.Specifically, the difference of Current communications frequency is default
Mode corresponds to different main carrier and secondary carrier.For example, Current communications frequency is 4G communication, then main carrier is PCC, secondary carrier
For SCC；Current communications frequency is 3G communication, then main carrier is C0, secondary carrier C1.
It should be understood that it is by all signal modulations a to spy that the mode of the transmission data of each communication cell, which is carrier wave,
Determine to emit by antenna again in frequency range, i.e., this frequency range is carrier wave.Each communication cell has the frequency range of oneself, if main load
The special frequency channel of wave modulation then determines that main carrier is small in the first communication in the range of the communication frequency Fa of the first communication cell
Area；, whereas if the special frequency channel of main carrier modulation is in the range of the communication frequency Fb of the second communication cell or other are logical
In the range of interrogating the corresponding communication frequency of cell, then determine that main carrier does not communicate cell first.
Step 104: if main carrier communicates cell first, it is dry to judge whether current MIPI frequency generates main carrier
It disturbs.
In the application, if Current communications frequency is preset mode, the corresponding main carrier of Current communications frequency is considered first
Whether the interference by current MIPI frequency, temporarily regardless of secondary carrier whether the interference by current MIPI.If main carrier does not have
Further consider in the case where interference by current MIPI frequency secondary carrier whether the interference by current MIPI frequency.Such as
Fruit Current communications frequency is not that preset mode considers further that the first communication cell, that is, considers whether Current communications cell is worked as
The interference of preceding MIPI frequency, hereafter does further explanation.
Specifically, the MIPI frequency of different functional modules being issued by base station of being possible to connect electronic device
Communication frequency generates interference, specifically, functional module includes display screen, camera, radio-frequency module etc. in different embodiments.With aobvious
For display screen, in order to avoid the MIPI frequency of display screen generates interference to communication frequency, the display screen in the same electronic device
At least two display screen MIPI frequencies are set, such as including display screen MIPI frequency A and display screen MIPI frequency B.Wherein show
Shield MIPI frequency A and Current communications cell is connected to electronic device, i.e., the communication frequency Fa of the first communication cell generates interference, still
To communication cell is closed on, i.e., the communication frequency Fb of the second communication cell will not generate interference.Display screen MIPI frequency B fills electronics
The the first communication cellular communication frequency Fa for setting connection will not generate interference, but may to the communication frequency of other cells, such as
Fb generates interference.It should be understood that main carrier or secondary carrier are vacation in the range of some corresponding communication frequency of communication cell
If current MIPI frequency has interference to the communication frequency of the first communication cell, if main carrier or secondary carrier are in the first communication
Cell, then there is also interference to the main carrier or secondary carrier for current MIPI frequency.
Such as step 102 has judged Current communications frequency as preset mode, and step 103 has judged that main carrier is logical first
Interrogate cell.Assuming that the communication frequency of electronic device connection is Current communications cell, i.e., the cell of the first communication corresponds to communication frequency
Rate Fa, if the current MIPI frequency that step 101 obtains is display screen MIPI frequency A, display screen MIPI frequency A can be interfered currently
The signal quality of cellular communication frequency Fa can also interfere with the signal transmission of main carrier, need to be implemented step 105.If step 101
The current MIPI frequency obtained is display screen MIPI frequency B, then display screen MIPI frequency B will not be interfered when the first communication cell pair
The signal quality of the communication frequency Fa answered will not generate interference to main carrier, not need to execute step 105, keep current
MIPI frequency is constant.
Step 105: if current MIPI frequency generates interference to main carrier, current MIPI frequency error factor is spare at first
MIPI frequency, wherein the first spare MIPI frequency does not interfere with the first communication cell.
Step 103 has judged that main carrier communicates cell first, and judges through step 104, if current MIPI frequency is to electricity
There is interference in the communication frequency for the first communication cell that sub-device has connected, that is, current MIPI frequency generates main carrier and does
It disturbs, then by current MIPI frequency error factor at the first spare MIPI frequency.First spare MIPI frequency does not have the first communication cell
Interference, namely main carrier is not interfered with, such as display screen MIPI frequency B, communication frequency Fa corresponding to the first communication cell
It does not interfere with, i.e., the main carrier in the first communication cell is not interfered with.Above only using the corresponding MIPI frequency of display screen as
Example carries out citing explanation, and the camera or radio-frequency module in electronic device similarly have multiple MIPI frequencies, has
MIPI frequency generates interference to current area communication frequency, and some MIPI frequencies generate interference to adjacent cells communication frequency, this
It does not do and illustrates one by one.Current MIPI frequency includes in display screen MIPI frequency, camera MIPI frequency and radio frequency MIPI frequency
At least one, refer to electronic device currently in the MIPI frequency of operation.First spare MIPI frequency also includes display screen
At least one of MIPI frequency, camera MIPI frequency and radio frequency MIPI frequency kind is electronic device currently without operation, is supplied
The MIPI frequency switched over when needs.
In one embodiment, if step 103 judges that main carrier does not communicate cell first, further whether main carrier is judged
Cell is communicated second, i.e., neighbouring communication cell.If main carrier communicates cell second, judge whether current MIPI frequency is right
Main carrier generate interference, it is possible to understand that if current MIPI frequency to second communication cell exist interference, to main carrier
There are interference.If current MIPI frequency generates interference to main carrier, by current MIPI frequency error factor at the second spare MIPI frequency,
Wherein the second spare MIPI frequency does not interfere with the second communication cell, does not just do to the main carrier in the second communication cell yet
It disturbs.Such as second communication cell corresponding communication frequency be Fb, main carrier second communication cell in, current MIPI frequency example
For example display screen MIPI frequency A, then display screen MIPI frequency A only communicates the corresponding communication frequency Fa of cell in the presence of dry to first
It disturbs, communication frequency Fb corresponding to second community is not interfered with, then there is no interference to main carrier for current MIPI frequency, at this time then
Keep current MIPI frequency without switching.Conversely, if current MIPI frequency is, for example, display screen MIPI frequency B, display screen
Only there is interference in communication frequency Fb corresponding to the second communication cell to MIPI frequency B, communication frequency corresponding to the first communication cell
Rate Fa is not interfered with, then current MIPI frequency has main carrier and interferes, and is needed current MIPI frequency error factor is spare at second
MIPI frequency, such as display screen MIPI frequency A.
In one embodiment, exists simultaneously multiple current MIPI frequencies and interference is generated to main carrier, it will be to master in the embodiment
That strongest MIPI frequency error factor of carrier-in-interference is at other spare MIPI frequencies.Specifically, in the embodiment, above step
104 specifically include: judging whether there is multiple current MIPI frequencies and generate interference to main carrier；If so, in multiple current MIPI frequencies
It is at least identified in rate and one or more stronger current MIPI frequency is interfered to main carrier interference.Above step 105 simultaneously
It include: that will at least to interfere stronger one or more current MIPI frequency be switched to corresponding first respectively main carrier spare
MIPI frequency.The embodiment will interfere main carrier the stronger multiple MIPI frequency error factors of strongest that or interference at other
Spare MIPI frequency, it is ensured that the signal of main carrier is good.
It referring to fig. 2, is the flow diagram of the application signal interference processing method second embodiment.The embodiment and upper the
The difference of one embodiment is, through judging, main carrier does not communicate cell first, does not also communicate cell second, i.e., currently
In the case that MIPI frequency does not interfere with main carrier, considers whether current MIPI frequency has secondary carrier and interfere.Specifically
The method comprising the steps of 201 to step 206, wherein step 201 to step 203 respectively with the step 101 of a upper embodiment to 103
Unanimously, this is specific without repeating:
Step 201: obtaining Current communications frequency, the corresponding main carrier of Current communications frequency, the first communication cell and work as
Preceding MIPI frequency.
Step 202: judging whether Current communications frequency is preset mode.
Step 203: if so, further judging main carrier whether in the first communication cell.
Step 204: if main carrier does not communicate cell first, further judging main carrier whether in second community.
Interference of the current MIPI frequency to main carrier is considered and excluded in the application first, therefore judges to lead through step 203
Carrier wave further judges main carrier whether in the second communication cell, to prevent main carrier not in the case where the first communication cell
In the second communication cell there is interference to the second communication cell in current MIPI frequency, thus there is also the feelings of interference to main carrier
Condition.
Step 205: if main carrier does not communicate cell second, it is dry to judge whether current MIPI frequency generates secondary carrier
It disturbs.
Judge by step 203 and step 204, if main carrier does not communicate cell first, also do not communicate cell second,
Then current MIPI frequency will not generate interference to main carrier, then it is dry further to judge whether current MIPI frequency generates secondary carrier
It disturbs.
Step 206: if current MIPI frequency generates interference to secondary carrier, current MIPI frequency error factor is spare at third
MIPI frequency, wherein the spare MIPI frequency of third does not interfere with secondary carrier.
Judge through step 205, if current MIPI frequency generates interference to secondary carrier, or is with the MIPI frequency of display screen
Example is explained.Such as current MIPI frequency is display screen MIPI frequency A, the cell that electronic device is currently communicated is first
Cell is communicated, the corresponding communication frequency of the first communication cell is Fa, and display screen MIPI frequency A generates the first communication cell dry
It disturbs, if the special frequency channel of secondary carrier modulation is in the range of the communication frequency Fa of the first communication cell, current MIPI frequency A is needed
The spare MIPI frequency of third is switched to, wherein the spare MIPI frequency of third does not interfere with secondary carrier, and further third is spare
MIPI frequency does not interfere with main carrier yet.Specifically, the spare MIPI frequency of such as third is display screen MIPI frequency B.
It is the flow diagram of signal interference processing method in the application 3rd embodiment referring to Fig. 3, the embodiment and the
The difference of one embodiment is that the Current communications frequency of electronic device is not preset mode, judges and exclude current MIPI frequency at this time
Rate whether there is signal interference to the first communication cell, i.e. Current communications cell, and whole flow process is as shown in figure 4, reality shown in Fig. 4
It applies and assumes that current MIPI frequency is A in example.Specifically, the method comprising the steps of 301 to step 305, wherein step 301 and step
302 in first embodiment step 101 and step 102 it is consistent, this is not repeated, specific:
Step 301: obtaining Current communications frequency, the corresponding main carrier of Current communications frequency, the first communication cell and work as
Preceding MIPI frequency.
Step 302: judging whether Current communications frequency is preset mode.
Step 303: if whether Current communications frequency is not to judge Current communications frequency in the first communication for preset mode
Cell.
Judged through step 302 if communication frequency is not as preset mode, that is, be not 4G or 3G, for example, 2G,
Then at this time consider first communication cell whether the interference by MIPI frequency.
Step 304: if Current communications frequency communicates cell first, judging current MIPI frequency whether to Current communications
Frequency generates interference.
Such as electronic device connection communication frequency be communication frequency Fa, that is, first communication cell, that is, Current communications it is small
The corresponding communication frequency in area, if the current preset MIPI frequency that step 301 obtains is display screen MIPI frequency A, display screen
MIPI frequency A can interfere the signal quality of the communication frequency Fa of the first communication cell, need to be implemented step 305.If step 301
The current preset MIPI frequency of acquisition is display screen MIPI frequency B, then display screen MIPI frequency B will not interfere the first communication cell
Communication frequency Fa signal quality, do not need to execute step 305, current MIPI frequency remains unchanged.
Step 305: if current MIPI frequency generates interference to Current communications frequency, by current MIPI frequency error factor at first
Spare MIPI frequency, wherein the first spare MIPI frequency does not interfere with the first communication cell.
Judge through step 304, if the communication for the first communication cell that current preset MIPI frequency has connected electronic device
There is interference in frequency, then by current preset MIPI frequency error factor at the first spare MIPI frequency.First spare MIPI frequency is to
One communication cell does not interfere with, such as display screen MIPI frequency B.Above only with the corresponding MIPI frequency of display screen as an example into
Row citing is explained, and the camera or radio-frequency module in electronic device similarly have multiple MIPI frequencies, some MIPI frequencies
Interference is generated to the communication frequency of the first communication cell, some MIPI frequencies communicate cell to adjacent cells namely second and lead to
News frequency rate generates interference, this does not do and illustrates one by one.Current preset MIPI frequency includes display screen MIPI frequency, camera MIPI frequency

Sub-device is currently without operation, the MIPI frequency that switches over when for needing.
In one embodiment, after judging the step of Current communications frequency is preset mode, further judge that main carrier is
It is no further comprising the steps of before the step of first communicates cell:
Judge whether the signal strength of main carrier is less than or equal to preset value, if the signal strength of main carrier is less than or equal to preset
Value, then carry out further judge main carrier whether first communicate cell the step of and other subsequent steps.Referring specifically to
Shown in Fig. 5, because only that main carrier signal is lower than some preset value, that is, when signal is weaker, current MIPI frequency
Influence to main carrier just can be bigger, very strong if the signal of main carrier itself, even if current MIPI frequency is to main carrier
There are interference, then actual influence is also little.So if the signal strength of main carrier is greater than preset value, i.e. the signal ratio of main carrier
When preferable, then influence of the current MIPI frequency to main carrier is not temporarily considered, but consider and exclude current MIPI frequency
Influence to secondary carrier assumes that current MIPI frequency is A in embodiment shown in fig. 5.
Specifically, if the signal strength of main carrier is greater than preset value, whether judging current MIPI frequency in an embodiment
Interference is generated to secondary carrier；If current MIPI frequency generates interference to secondary carrier, and current MIPI frequency error factor is standby at third
With MIPI frequency, wherein the spare MIPI frequency of third does not interfere with secondary carrier.
It is the flow diagram of the application signal interference processing method fourth embodiment referring to Fig. 6.The embodiment and upper the
The difference of three embodiments is, in the communication frequency for guaranteeing the first communication cell that electronic device has connected not by electronic device
While the currently running MIPI frequency of inner function module is interfered, it is ensured that preferable adjacent cell of signal is namely
The communication frequency of second communication cell is not also interfered by the currently running MIPI frequency of electronic device inner function module.So as to
When so that the first communication cell signal is poor or unstable, it is small that preferable second communication of signal can be immediately switched to
