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. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. 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.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The execution main body of the signal interference processing method provided by the embodiment of the present application may be a signal interference processing device provided by the embodiment of the present application, or an electronic device (such as a notebook, a palmtop computer, a tablet computer, a smart phone, a vehicle-mounted smart device, etc.) integrated with the signal interference processing method.
Referring to fig. 1, a schematic flow chart of a first embodiment of a signal interference processing method according to an embodiment of the present application is shown, where the method includes steps 101 to 105, where:
step 101: the method comprises the steps of obtaining a current communication frequency, a main carrier corresponding to the current communication frequency, a first communication cell and a current MIPI frequency.
It will be appreciated that electronic devices such as handsets may operate over wired, wireless or satellite-based communication systems that transmit data in frames or packets. The control interface used by the Communication System may include Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Global System for Mobile Communication (GSM), Digital Cellular System (DCS), and the like.
Taking the GSM communication system as an example, the GSM communication system may include a plurality of mobile terminals, a plurality of base stations, a base station controller, and a mobile switching center. Each base station can serve a plurality of areas, namely a first communication cell and a second communication cell, each base station is provided with a plurality of multi-directional antennas or antennas pointing to characteristic directions, signals transmitted by the antennas can cover the service area corresponding to the base station, and each service area can be covered by one or more than one antenna. The communication frequency used by the electronic devices such as mobile phones to surf the internet or to communicate comes from the base station, and different base stations have different communication frequencies. The base station receives the communication signal sent by the mobile terminal, transmits the received communication signal to the base station controller, and transmits the communication signal to the mobile switching center for signal switching by the base station controller, so as to realize the communication connection between the current mobile terminal user and the internet or other network users.
In a cellular system, each area is divided into a number of communication cells, each cell being assigned a different set of channels to achieve frequency reuse. In the communication process, signals are transmitted in a carrier mode, the frequency of the transmitted data is low, and if the signals are transmitted according to the frequency of the data, the receiving and the synchronization are not facilitated. By using carrier transmission, a data signal can be loaded on the carrier signal, a receiving party receives the data signal according to the frequency of the carrier, the amplitude of a meaningful signal wave is different from that of a meaningless signal, and the signals are extracted to be the data signal required by the user. The specific carrier is that all signals are modulated to a specific frequency band and then transmitted through an antenna, that is, the frequency band is the carrier. For example, in a 3G system, since code division multiple access is adopted, one frequency point can be reused by many sectors, and one communication cell, one base station, and the like can form one carrier or several carriers.
The current communication frequency is a frequency currently used by the electronic device for communication, and the specific current communication frequency may have a plurality of modes, such as 4G communication, 3G communication, or 2G communication. Each current communication frequency may transmit a signal by means of a carrier wave. Specifically, the current communication frequency includes a corresponding primary carrier and a corresponding secondary carrier, the primary carrier is used for transmitting and receiving data, and the secondary carrier is only used for receiving data in an auxiliary manner, but not for transmitting data.
The communication cell where the communication frequency currently connected to the electronic device, such as a mobile phone, is located, is the current communication cell, that is, the first communication cell in step 101, and usually the first communication cell is a communication cell covered by the communication frequency sent by the base station closest to the electronic device. The communication cell corresponding to the communication frequency transmitted by the other base station but not connected to the electronic device is a second communication cell, also called a neighboring communication cell, which may be one or more. Hereinafter, the communication frequency of the first cell is defined as Fa, and the communication frequency of the second cell is defined as Fb.
In the embodiment of the present application, MIPI in MIPI frequency is entirely called Mobile Industry Processor Interface in english, and is entirely called Mobile Industry Processor Interface in chinese. The MIPI frequency can be determined after the circuit diagram of the equipment is designed and shaped, the MIPI frequency can be read in a memory of the equipment, and the MIPI frequency input by a user can be received. Different functional modules have different MIPI frequencies, for example, a display screen and a camera both have respective MIPI frequencies.
Step 102: and judging whether the current communication frequency is in a preset mode or not.
Specifically, different electronic devices have different functions, and therefore, different communication frequencies are used. The preset mode of the current communication frequency in step 102 includes 4G communication or 3G communication. It can be understood that the communication frequency used for the electronic device such as a mobile phone to access the internet or to communicate with the electronic device comes from a base station, and different base stations have different communication frequencies, for example, a 4G mode is adopted when the electronic device accesses the internet, and a 3G or 2G mode is adopted when the electronic device makes a call. When the communication frequency of the electronic device is 4G or 3G, the mode is the preset mode, and the 2G mode is not the preset mode.
Step 103: if yes, further judging whether the main carrier is in the first communication cell.
The current communication frequency includes a corresponding primary carrier and a corresponding secondary carrier. Specifically, different preset modes of the current communication frequency correspond to different main carriers and different auxiliary carriers. For example, if the current communication frequency is 4G communication, the primary carrier is PCC and the secondary carrier is SCC; if the current communication frequency is 3G communication, the primary carrier is C0, and the secondary carrier is C1.
It can be understood that the data transmission mode of each communication cell is that the carrier wave modulates all signals to a specific frequency band and then transmits the signals through the antenna, that is, the frequency band is the carrier wave. Each communication cell has a frequency band, and if the specific frequency band modulated by the main carrier is within the range of the communication frequency Fa of the first communication cell, the main carrier is judged to be in the first communication cell; on the contrary, if the specific frequency band modulated by the primary carrier is within the range of the communication frequency Fb of the second communication cell or within the range of the communication frequency corresponding to other communication cells, it is determined that the primary carrier is not in the first communication cell.
Step 104: and if the main carrier is in the first communication cell, judging whether the current MIPI frequency generates interference on the main carrier.
In the present application, if the current communication frequency is in the preset mode, whether the primary carrier corresponding to the current communication frequency is interfered by the current MIPI frequency is considered first, and whether the secondary carrier is interfered by the current MIPI is considered temporarily. If the main carrier is not interfered by the current MIPI frequency, whether the auxiliary carrier is interfered by the current MIPI frequency or not is further considered. The first communication cell is considered if the current communication frequency is not in the predetermined mode, that is, whether the current communication cell is interfered by the current MIPI frequency is considered, which is further explained below.
Specifically, the MIPI frequencies of different functional modules may interfere with the communication frequency sent by the base station to which the electronic device is connected, and specifically, the functional modules in different embodiments include a display screen, a camera, a radio frequency module, and the like. Taking a display screen as an example, in order to avoid the interference of the MIPI frequency of the display screen to the communication frequency, at least two display screen MIPI frequencies are set on the display screen in the same electronic device, for example, the display screen MIPI frequencies include a display screen MIPI frequency a and a display screen MIPI frequency B. The display screen MIPI frequency a interferes with the communication frequency Fa of the current communication cell, i.e. the first communication cell, to which the electronic device is connected, but does not interfere with the communication frequency Fb of the adjacent communication cell, i.e. the second communication cell. The display screen MIPI frequency B does not interfere with the first communication cell communication frequency Fa to which the electronic device is connected, but may interfere with the communication frequencies of other cells, such as Fb. It can be understood that, in a range where the primary carrier or the secondary carrier is a communication frequency corresponding to a certain communication cell, it is assumed that the current MIPI frequency interferes with the communication frequency of the first communication cell, and if the primary carrier or the secondary carrier is in the first communication cell, the current MIPI frequency also interferes with the primary carrier or the secondary carrier.
For example, step 102 determines that the current communication frequency is in the default mode, and step 103 determines that the primary carrier is in the first communication cell. Assuming that the communication frequency connected to the electronic device is the current communication cell, i.e., the first communication cell, which corresponds to the communication frequency Fa, if the current MIPI frequency obtained in step 101 is the display screen MIPI frequency a, the display screen MIPI frequency a may interfere with the signal quality of the current cell communication frequency Fa and may also interfere with the signal transmission of the main carrier, and step 105 needs to be performed. If the current MIPI frequency obtained in step 101 is the display screen MIPI frequency B, the display screen MIPI frequency B does not interfere with the signal quality of the communication frequency Fa corresponding to the first communication cell, and does not interfere with the host carrier, and step 105 does not need to be executed, and the current MIPI frequency is kept unchanged.
Step 105: if the current MIPI frequency generates interference on the main carrier, the current MIPI frequency is switched into a first standby MIPI frequency, and the first standby MIPI frequency does not interfere with the first communication cell.
Step 103 determines that the primary carrier is in the first communication cell, and if the current MIPI frequency interferes with the communication frequency of the first communication cell to which the electronic device is connected, that is, the current MIPI frequency interferes with the primary carrier, step 104 determines to switch the current MIPI frequency to the first standby MIPI frequency. The first standby MIPI frequency does not interfere with the first communication cell, that is, does not interfere with the host carrier, for example, the display screen MIPI frequency B does not interfere with the communication frequency Fa corresponding to the first communication cell, that is, does not interfere with the host carrier in the first communication cell. The above explanation is given by taking the MIPI frequency corresponding to the display screen as an example, and a camera or a radio frequency module in the electronic device also has multiple MIPI frequencies, some MIPI frequencies interfere with the communication frequency of the current cell, and some MIPI frequencies interfere with the communication frequency of the neighboring cell, which is not given by way of example. The current MIPI frequency includes at least one of a display screen MIPI frequency, a camera MIPI frequency, and a radio frequency MIPI frequency, and refers to the MIPI frequency at which the electronic device is currently operating. The first standby MIPI frequency also comprises at least one of display screen MIPI frequency, camera MIPI frequency and radio frequency MIPI frequency, and the MIPI frequency is used for switching when the electronic device is not operated at present.
In one embodiment, if the primary carrier is not in the first cell in step 103, it is further determined whether the primary carrier is in the second cell, i.e., the neighboring cell. If the primary carrier is in the second communication cell, whether the current MIPI frequency interferes with the primary carrier is judged, and it can be understood that if the current MIPI frequency interferes with the second communication cell, the interference also exists with the primary carrier. If the current MIPI frequency generates interference on the main carrier, the current MIPI frequency is switched to a second standby MIPI frequency, wherein the second standby MIPI frequency does not interfere with a second communication cell, and the main carrier in the second communication cell is not interfered. For example, the corresponding communication frequency of the second communication cell is Fb, the host carrier is in the second communication cell, and the current MIPI frequency is, for example, display screen MIPI frequency a, then the display screen MIPI frequency a only interferes with the communication frequency Fa corresponding to the first communication cell, and does not interfere with the communication frequency Fb corresponding to the second cell, then the current MIPI frequency does not interfere with the host carrier, and at this time, the current MIPI frequency is kept without switching. On the contrary, if the current MIPI frequency is, for example, the display screen MIPI frequency B only has interference on the communication frequency Fb corresponding to the second communication cell, and does not have interference on the communication frequency Fa corresponding to the first communication cell, the current MIPI frequency has interference on the primary carrier, and the current MIPI frequency needs to be switched to a second standby MIPI frequency, for example, the display screen MIPI frequency a.
In an embodiment where there are multiple simultaneous current MIPI frequencies interfering with the primary carrier, the MIPI frequency with the strongest interference with the primary carrier is switched to another alternate MIPI frequency. Specifically, in this embodiment, the step 104 specifically includes: judging whether a plurality of current MIPI frequencies generate interference on a main carrier; if yes, at least one or more current MIPI frequencies which have stronger interference on the main carrier are identified from the current MIPI frequencies. Meanwhile, the above step 105 includes: at least one or more current MIPI frequencies with stronger interference to the main carrier are respectively switched to corresponding first standby MIPI frequencies. The embodiment switches the MIPI frequency with the strongest interference or the plurality of MIPI frequencies with stronger interference to the main carrier into other standby MIPI frequencies, and ensures that the signal of the main carrier is good.
Fig. 2 is a schematic flowchart of a signal interference processing method according to a second embodiment of the present application. The difference between this embodiment and the first embodiment is that, after determining that the primary carrier is not in the first cell or the second cell, that is, when the current MIPI frequency does not interfere with the primary carrier, whether the current MIPI frequency interferes with the secondary carrier is considered. Specifically, the method includes steps 201 to 206, where steps 201 to 203 are consistent with steps 101 to 103 of the previous embodiment, which is not described herein, specifically:
step 201: the method comprises the steps of obtaining a current communication frequency, a main carrier corresponding to the current communication frequency, a first communication cell and a current MIPI frequency.
Step 202: and judging whether the current communication frequency is in a preset mode or not.
Step 203: if yes, further judging whether the main carrier is in the first communication cell.
Step 204: if the primary carrier is not in the first communication cell, whether the primary carrier is in the second cell is further judged.
In the present application, the interference of the current MIPI frequency to the primary carrier is considered and eliminated first, so that it is further determined whether the primary carrier is in the second communication cell or not under the condition that the primary carrier is determined not to be in the first communication cell in step 203, so as to prevent the interference of the current MIPI frequency to the second communication cell when the primary carrier is in the second communication cell, and thus the interference to the primary carrier also exists.
Step 205: and if the main carrier is not in the second communication cell, judging whether the current MIPI frequency generates interference on the auxiliary carrier.
Through the judgment of step 203 and step 204, if the primary carrier is not in the first communication cell and not in the second communication cell, the current MIPI frequency does not interfere with the primary carrier, and then whether the current MIPI frequency interferes with the secondary carrier is further judged.
Step 206: and if the current MIPI frequency generates interference on the auxiliary carrier, switching the current MIPI frequency into a third standby MIPI frequency, wherein the third standby MIPI frequency does not have interference on the auxiliary carrier.
In step 205, if the current MIPI frequency interferes with the auxiliary carrier, the explanation is performed by taking the MIPI frequency of the display screen as an example. For example, the current MIPI frequency is display screen MIPI frequency a, a cell in which the electronic device currently communicates is a first communication cell, a communication frequency corresponding to the first communication cell is Fa, the display screen MIPI frequency a interferes with the first communication cell, and if a specific frequency band modulated by the auxiliary carrier is within the range of the communication frequency Fa of the first communication cell, the current MIPI frequency a needs to be switched to a third standby MIPI frequency, where the third standby MIPI frequency does not interfere with the auxiliary carrier, and further the third standby MIPI frequency does not interfere with the main carrier. Specifically, for example, the third standby MIPI frequency is display screen MIPI frequency B.
Referring to fig. 3, a schematic flowchart of a signal interference processing method in a third embodiment of the present invention is shown, where the difference between the embodiment and the first embodiment is that a current communication frequency of an electronic device is not in a preset mode, and at this time, whether signal interference exists in a first communication cell, i.e., the current communication cell, is determined and excluded, and a whole flow is shown in fig. 4, where it is assumed that the current MIPI frequency is a in the embodiment shown in fig. 4. Specifically, the method includes steps 301 to 305, where steps 301 and 302 are consistent with steps 101 and 102 in the first embodiment, which is not repeated herein, and specifically:
step 301: the method comprises the steps of obtaining a current communication frequency, a main carrier corresponding to the current communication frequency, a first communication cell and a current MIPI frequency.
Step 302: and judging whether the current communication frequency is in a preset mode or not.
Step 303: if the current communication frequency is not in the preset mode, judging whether the current communication frequency is in the first communication cell.
If the communication frequency is not in the predetermined mode, i.e. not 4G or 3G, for example, 2G, as determined in step 302, then it is considered whether the first communication cell is interfered by the MIPI frequency.
Step 304: and if the current communication frequency is in the first communication cell, judging whether the current MIPI frequency generates interference on the current communication frequency.
For example, the communication frequency connected to the electronic device is the communication frequency Fa, that is, the communication frequency corresponding to the first communication cell, that is, the current communication cell, and if the current preset MIPI frequency obtained in step 301 is the display screen MIPI frequency a, the display screen MIPI frequency a may interfere with the signal quality of the communication frequency Fa of the first communication cell, and step 305 needs to be executed. If the current preset MIPI frequency obtained in step 301 is the display screen MIPI frequency B, the display screen MIPI frequency B does not interfere with the signal quality of the communication frequency Fa of the first communication cell, and step 305 does not need to be executed, and the current MIPI frequency remains unchanged.
Step 305: if the current MIPI frequency generates interference on the current communication frequency, the current MIPI frequency is switched to a first standby MIPI frequency, and the first standby MIPI frequency does not interfere with the first communication cell.
If the current predetermined MIPI frequency interferes with the communication frequency of the first communication cell to which the electronic device is connected, the current predetermined MIPI frequency is switched to the first standby MIPI frequency, as determined in step 304. The first standby MIPI frequency does not interfere with the first communication cell, such as display screen MIPI frequency B. The above explanation is given by taking the MIPI frequency corresponding to the display screen as an example, and a camera or a radio frequency module in the electronic device also has a plurality of MIPI frequencies, some MIPI frequencies interfere with the communication frequency of the first communication cell, and some MIPI frequencies interfere with the communication frequency of the neighboring cell, that is, the second communication cell, which is not illustrated one by one. The current preset MIPI frequency includes at least one of a display screen MIPI frequency, a camera MIPI frequency, and a radio frequency MIPI frequency, which refers to the MIPI frequency at which the electronic device is currently operating. The first standby MIPI frequency also comprises at least one of display screen MIPI frequency, camera MIPI frequency and radio frequency MIPI frequency, and the MIPI frequency is used for switching when the electronic device is not operated at present.
In an embodiment, after the step of determining that the current communication frequency is in the predetermined mode, the step of further determining whether the primary carrier is in the first communication cell further includes the following steps:
and judging whether the signal intensity of the main carrier is less than or equal to a preset value, and if the signal intensity of the main carrier is less than or equal to the preset value, further judging whether the main carrier is in the first communication cell and other subsequent steps. As shown in fig. 5, only when the signal of the main carrier is lower than a predetermined value, that is, the signal is weak, the influence of the current MIPI frequency on the main carrier is large, and if the signal of the main carrier is strong, even if the current MIPI frequency interferes with the main carrier, the actual influence is not large. Therefore, if the signal strength of the primary carrier is greater than the preset value, that is, when the signal of the primary carrier is relatively good, the influence of the current MIPI frequency on the primary carrier is not considered for the moment, but the influence of the current MIPI frequency on the secondary carrier is considered and eliminated, and it is assumed that the current MIPI frequency is a in the embodiment shown in fig. 5.
Specifically, in an embodiment, if the signal strength of the primary carrier is greater than a preset value, it is determined whether the current MIPI frequency interferes with the secondary carrier; and if the current MIPI frequency generates interference on the auxiliary carrier, switching the current MIPI frequency into a third standby MIPI frequency, wherein the third standby MIPI frequency does not have interference on the auxiliary carrier.
Fig. 6 is a schematic flowchart of a signal interference processing method according to a fourth embodiment of the present application. The difference between this embodiment and the third embodiment is that while it is ensured that the communication frequency of the first communication cell to which the electronic device is already connected is not interfered by the MIPI frequency currently operated by the internal functional module of the electronic device, it is also ensured that the communication frequency of the neighboring cell with better signal, that is, the second communication cell, is also not interfered by the MIPI frequency currently operated by the internal functional module of the electronic device. Therefore, when the signal of the first communication cell is poor or unstable, the communication frequency of the second communication cell with a better signal can be immediately switched, and meanwhile, the interference of the currently running MIPI frequency of the internal functional module of the electronic device is avoided, and the communication quality is ensured. Specifically, the method includes steps 401 to 405, where steps 401 to 403 are consistent with steps 301 to 303 of the previous embodiment, which is not described herein again, specifically:
step 401: the method comprises the steps of obtaining a current communication frequency, a main carrier corresponding to the current communication frequency, a first communication cell and a current MIPI frequency.
Step 402: and judging whether the current communication frequency is in a preset mode or not.
Step 403: if the current communication frequency is not in the preset mode, judging whether the current communication frequency is in the first communication cell.
Step 404: if the current communication frequency is not in the first communication cell, whether the current communication frequency is in the second communication cell is further judged.
In this embodiment, on the premise that it is determined that the current MIPI frequency does not interfere with the communication frequency of the first communication cell, the interference condition of the current MIPI frequency with the communication frequency of the second communication cell is further considered. Communication frequencies other than the current cell communication frequency to which the electronic device has been connected are first acquired. I.e. the communication frequency transmitted by other base stations but not currently used by the electronic device, the communication frequency with the best signal is defined as the second communication frequency. Specifically, one or more neighboring cell communication frequencies may be acquired, which is not particularly limited.
Step 405: and if the current communication frequency is in the second communication cell, judging whether the current MIPI frequency generates interference on the second communication cell.
And judging whether the current MIPI frequency of the electronic device in operation generates interference on the communication frequency of the second communication cell, if so, executing the step 406, and if not, executing the step 406.
Step 406: if the current MIPI frequency interferes with the signal frequency of the current communication cell, the current MIPI frequency is switched to a second standby MIPI frequency, wherein the second standby MIPI frequency does not interfere with the second communication cell, and the second standby MIPI frequency does not interfere with the first communication cell.
After step 405, if the current MIPI frequency of the electronic device is operating and interferes with the communication frequency of the second communication cell, the current MIPI frequency is switched to the second standby frequency.
