Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the description of the present application, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it should be noted that, unless expressly specified and limited otherwise, "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art. Furthermore, in the description of the present application, unless otherwise indicated, "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

In the related art, a processing manner of preventing signal interference is to add a filter network or a filter device to an internal circuit of an electronic device to perform signal filtering on interference frequency bands of communication networks of other systems. However, in this way, on the one hand: when the information amount on the communication network of each system is continuously increased, the bandwidth and throughput of the communication signal of the corresponding electronic device are also continuously increased, and at this time, the complex communication scene cannot be dealt with due to the limitation of the filtering effect in the above manner, so that the communication function failure of the electronic device, such as the situations of noise on making a phone call, network card on or off, reconnection and no signal, etc., occur. On the other hand, the above-mentioned method can only filter the interference factor of the radio frequency signal of a certain communication network of the electronic device, but the "certain communication network" lacks means for identifying the interfered frequency band, and does not process from the dimension of the interfered frequency band, so that the effect of signal anti-interference processing is not good.

The present application will be described in detail with reference to specific examples.

In one embodiment, as shown in fig. 1, a signal interference processing method is specifically proposed, which may be implemented by means of a computer program and may be run on a signal interference processing device based on von neumann system. The computer program may be integrated in the application or may run as a stand-alone tool class application.

Wherein, the signal interference device may be an electronic device, and the electronic device includes but is not limited to: wearable devices, handheld devices, personal computers, tablet computers, vehicle-mounted devices, smart phones, computing devices, or other processing devices connected to a wireless modem, etc. The electronic devices may be called different names in different networks, for example: a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or user equipment, a cellular telephone, a cordless telephone, a personal digital assistant (personal digital assistant, PDA), a terminal device in a 5G network or a future evolution network, and the like.

Specifically, the signal interference processing method comprises the following steps:

step S101: and receiving a radio frequency signal transmitted by a communication network, and determining a signal frequency band of the radio frequency signal.

The communication network refers to a network that complies with any suitable communication standard, such as New Radio (NR), long Term Evolution (LTE), LTE-advanced (LTE-a), wideband Code Division Multiple Access (WCDMA), high Speed Packet Access (HSPA), CDMA2000, time division synchronous code division multiple access (TD-CDMA), etc. Furthermore, communication between devices in a communication network may be performed according to any suitable communication protocol, such as, in embodiments of the present application, the transceiving of radio frequency signals by an electronic device and the communication network, including, but not limited to, the Global System for Mobile communications (GSM), universal Mobile Telecommunications System (UMTS), long Term Evolution (LTE), and/or other suitable communication protocols, such as first generation (1G), second generation (2G), 2.5G, 2.75G, 3G, 4G, 4.5G, 5G communication protocols, wireless Local Area Network (WLAN) standards (such as the IEEE 802.11 standards); and/or any other suitable wireless communication standard, and/or any other presently known or future developed protocol.

In practical applications, radio frequency signals of a communication network received by an electronic device are actually transmitted for network devices in the communication network, such as a Base Station (BS), an Access Point (AP), a repeater, and the like. The transmission of radio frequency signals from network devices to electronic devices in a communication network is often referred to as Downlink (DL) transmission and the transmission in the opposite direction is referred to as Uplink (UL) transmission. When the network device transmits radio frequency signals within the signal transmission time, such as when the network device in a communication network transmits outwards in a beam mode, the electronic device for signal reception may receive radio frequency signals transmitted by the communication network through the included antenna. The electronic equipment can analyze the radio frequency signals to determine the signal frequency bands of the radio frequency signals.

Step S102: and determining the interfered frequency band existing in the signal frequency band based on the frequency band range information of the signal frequency band.

The frequency range information is used for determining whether frequency range interference of other communication systems exists in the signal frequency range, such as coexistence interference, and determining an interfered frequency range existing in the signal frequency range, further, the frequency range information may be preset amplitude-frequency characteristics in a corresponding frequency range, such as amplitude-frequency characteristics of signals in the signal frequency range, and it may be understood that when the amplitude-frequency characteristics corresponding to the signal frequency range do not meet the frequency range information, the interfered frequency range exists in the signal frequency range. Further, in practical applications, the frequency band range corresponding to the signal frequency band is usually large, and the frequency band that is often interfered belongs to a portion (such as a small segment) of the signal frequency band, in the embodiment of the present application, based on the frequency band range information, an accurate decision may be performed on the signal frequency band, so as to determine whether the signal frequency band is interfered and the interfered frequency band existing in the signal frequency band.

Specifically, in the channel transmission of the radio frequency signal, when there is interference in a frequency band corresponding to the radio frequency signal, for example, the radio interference may be at least one of co-frequency interference, adjacent channel interference, out-of-band interference, intermodulation interference, blocking interference and other interference conditions in a certain portion of the frequency band, the radio interference signal may be coupled with the radio frequency signal of the communication network by a direct coupling or an indirect coupling manner, so that electromagnetic energy entering into a channel or a system of a receiving device (i.e., an electronic device) may affect the reception of the radio frequency signal required by radio communication by the electronic device, resulting in performance degradation, quality degradation, information error or loss of the radio frequency signal, and even blocking the progress of communication. It should be noted that, coexistence interference between two or more wireless communication modules in an electronic device, such as a wireless communication network and a bluetooth communication network, a wireless communication network and a wireless local area network, etc., are also applicable to the embodiments of the present application.

In the embodiment of the application, when the electronic device is registered on the communication network for the first time, some reference communication parameters (which can be understood as communication parameters without interference signals) of the signal frequency band of the radio frequency signal corresponding to the communication network are correspondingly acquired, for example, fitting of one or more of parameters such as spectrum parameters, amplitude parameters, power energy parameters and the like of the signal frequency band. The electronic device may determine corresponding frequency range information, such as a threshold value corresponding to the spectrum parameter, a critical value corresponding to the amplitude parameter, a threshold value corresponding to the power energy parameter, and so on, based on the information (reference communication parameters). After the electronic device receives the radio frequency signal, only the signal frequency band of the radio frequency signal needs to be determined, and then signal analysis, such as spectrum analysis, is performed on the radio frequency signal in the signal frequency band, and usually, the waveform of the radio frequency signal is continuous.

The processing method may be that the electronic device performs spectrum analysis on the radio frequency signal in the signal frequency band, for example, performs fourier transform on the radio frequency signal, so as to obtain a spectrum of the radio frequency signal, and then the electronic device may determine, based on a threshold value (which may be referred to as a spectrum threshold value) corresponding to a spectrum parameter in the frequency band range information, whether the spectrum of the radio frequency signal at each frequency band point meets the spectrum threshold value, if the spectrum at an abnormal frequency band point is higher than the spectrum threshold value, then the electronic device may determine, based on the abnormal frequency band point, an interfered frequency band existing in the signal frequency band. For example, the electronic device may continuously acquire two abnormal frequency band points, and take the frequency band corresponding to the two abnormal frequency band points as an "interfered frequency band", for example, the electronic device may determine the "interfered frequency band" by taking the first and the last two abnormal frequency band points from the plurality of abnormal frequency band points, for example, the electronic device may determine an "interfered frequency band" by taking a preset frequency band interval as a radius based on the abnormal frequency band point as a center point, and so on.

The processing mode may be that the electronic device performs amplitude analysis on the radio frequency signal in the signal frequency band, extracts amplitude characteristics (such as instantaneous amplitude, phase and instantaneous power) of the radio frequency signal, determines whether the amplitude characteristics change of each frequency band point is within the amplitude characteristic change range in the frequency band range information, for example, whether the instantaneous amplitude change exceeds an amplitude threshold value, the divergence rate of the instantaneous amplitude is higher than a threshold value, and the like, and when the amplitude characteristics change of a certain abnormal frequency band point is not within the amplitude characteristic change range, the electronic device may determine the disturbed frequency band existing in the signal frequency band based on the abnormal frequency band point.

In a possible implementation manner, in order to more accurately determine the interfered frequency band existing in the signal frequency band, the signal frequency band corresponding to the radio frequency signal may be preprocessed before the judgment, for example, the signal frequency band is compensated, and the radio frequency signal in the signal frequency band is filtered. Etc.

Step S103: and determining a target frequency band outside the interfered frequency band, and reporting the target frequency band to the communication network, wherein the target frequency band is used for indicating the communication network to transmit a next radio frequency signal in the target frequency band.

The target frequency band is a non-interference frequency band, that is, a frequency band other than the interfered frequency band, and may be a target frequency band in the signal frequency band corresponding to the radio frequency signal, or may be a frequency band other than the signal frequency band corresponding to the radio frequency signal.

Specifically, the electronic device performs signal frequency band identification in advance on the signal frequency band of the radio frequency signal transmitted by the received communication network, determines an interference frequency band in the signal frequency band, and then reports the determined target frequency band to the communication network, so that the communication network is instructed to transmit the next radio frequency signal to the electronic device by taking the target frequency band as a reference after receiving the target frequency band reported by the electronic device. Therefore, interference frequency band avoidance is realized on the electronic equipment side, and received signals are demodulated or transmitted signals are encrypted by utilizing other determined target frequency bands, so that the phenomena of error codes and messy codes of transmitted signals can be reduced, and the accuracy and the integrity of useful signals are improved.

Specifically, the electronic device may store a frequency band sequence corresponding to the communication network in advance, where the frequency band sequence may be understood as a plurality of reference radio frequency bands supportable by the communication network, where the frequency band sequence may be a supported frequency band sequence acquired from the communication network when the electronic device first hosts the communication network; and/or, the frequency band sequence may be a reference radio frequency band with better frequency band quality determined by performing frequency band analysis on each scanned frequency band when the electronic device turns on frequency band scanning for a long time; and/or the frequency band sequence may be a frequency band sequence generated by the electronic device acquiring the reference frequency bands of other electronic devices for the communication network based on big data analysis. Further, the electronic device may determine a target frequency band other than the interfered frequency band based on the frequency band sequence, that is, the electronic device may determine a frequency band other than the interfered frequency band among a plurality of reference radio frequency bands included in the frequency band sequence as the target frequency band, and further, when the determined "frequency band other than the interfered frequency band among the plurality of reference radio frequency bands" is a plurality of frequency bands, the electronic device may perform sweep analysis on the plurality of radio frequency bands, and determine an optimal target frequency band based on a result of the sweep analysis. And finally reporting the target frequency band to the communication network.

Alternatively, the electronic device may send a signal in the determined target frequency band when communicating to the communication network, for example, send information about the target frequency band to the communication network.

In the embodiment of the application, the electronic equipment receives the radio frequency signal transmitted by the communication network, determines the signal frequency band of the radio frequency signal, determines the interfered frequency band existing in the signal frequency band based on the frequency band range information of the signal frequency band, and then determines the target frequency band outside the interfered frequency band, so as to report the target frequency band to the communication network, wherein the target frequency band is used for indicating the communication network to transmit the next radio frequency signal in the target frequency band. The method comprises the steps of identifying the interfered frequency band of the signal frequency band corresponding to the emergent frequency signal, determining the target frequency band outside the interfered frequency band and reporting to the communication network, so that the problem that the signal anti-interference effect is not high due to the interference frequency band in a complex communication scene can be avoided, the identified interference frequency band is avoided at the electronic equipment side, the non-interfered target frequency band is utilized to communicate with the communication network, the signal anti-interference effect can be greatly improved, and the error code and messy code phenomena in the signal transmission process are reduced; and based on the frequency band range information of the signal frequency band, the interfered frequency band existing in the signal frequency band can be accurately determined, so that the accurate avoidance of the interfered frequency band is realized.

Referring to fig. 2, fig. 2 is a flow chart illustrating another embodiment of a signal interference processing method according to the present application. Specific:

step S201: and receiving a radio frequency signal transmitted by a communication network, and determining a signal frequency band of the radio frequency signal.

See step S101, and will not be described here.

Step S202: and determining a target frequency band range to which the signal frequency band belongs in at least one preset frequency band range.

In practical application, the frequency range corresponding to the signal frequency range is usually large, and the frequency range which is often interfered belongs to a part (such as a small section) of the signal frequency range, in the embodiment of the application, the electronic equipment is preset with a plurality of preset frequency range, and each preset frequency range can be divided equally or differently, namely, the corresponding range of each frequency range can be inconsistent in size; further, the frequency range may be reasonably determined in combination with various types of communication systems supported by the electronic device, for example, a certain communication system may correspond to multiple frequency bands, for example, a chinese mobile GSM system includes a 900MHz frequency band and an 1800MHz frequency band, and a chinese telecommunication CDMA system includes an 800MHz frequency band. In one example, when the network information is MCC and MNC, and MCC is 460 and MNC is 2, the frequency bands corresponding to the network information are 900MHz band and 1800MHz band. When the network information is MCC and MNC, and MCC is 460 and MNC is 03, the frequency band corresponding to the network information is 800 MHz. The electronic device may further subdivide the frequency band range based on the frequency band parameters, for example, 900MHz-1800MHz as a preset frequency band range, 900MHz-1000MHz as a preset frequency band range, and so on, which is not specifically limited. Specifically, the electronic device may determine the target frequency band range to which the signal frequency band belongs based on the "at least one preset frequency band range". As shown in fig. 3, fig. 3 is a schematic diagram corresponding to a plurality of preset frequency ranges, which includes a plurality of preset frequency ranges, such as Main Frequency Band group1, main Frequency Band group2, main Frequency Band group3, main Frequency Band group4,

Each preset frequency range is formed by a plurality of sub-frequency bands, for example Main Frequency Band group 1. Main Frequency Band group1 includes the sub-bands Sub Frequency Band, sub Frequency Band2, sub Frequency Band3, etc. It should be noted that, when a plurality of preset frequency ranges and a plurality of sub-frequency bands corresponding to the preset frequency ranges are set and divided, corresponding interference judgment information (a standard for identifying an interference frequency band) is set for each sub-frequency band, for example, preset frequency range characteristics in the corresponding sub-frequency band, and an actual signal frequency band is analyzed based on the preset frequency range characteristics, so that a target frequency band with interference, that is, an interference frequency band, is determined. Further, different sub-bands may correspond to the same interference decision information, or may correspond to different interference decision information, which is specifically determined according to an actual application environment, and is not specifically limited herein.

Take fig. 3 as an example. The electronic device may determine, after acquiring the signal frequency band corresponding to the radio frequency signal, a target frequency band range within which the signal frequency band falls in a plurality of preset frequency band ranges, for example, the electronic device determines that the signal frequency band belongs to the target signal frequency band Main Frequency Band group, and then performs further accurate determination based on the target signal frequency band to determine whether the signal frequency band is interfered and whether the interfered frequency band exists in the signal frequency band.

Step S203: and determining a first sub-frequency band corresponding to the signal frequency band in at least one sub-frequency band contained in the target frequency band range.

Specifically, after the electronic device determines the target frequency band range, it needs to further accurately determine the first sub-frequency band corresponding to the signal frequency band to combine with the interference judgment condition of the sub-frequency band to achieve the purpose of further determining the target frequency band. The method generally determines that the first sub-band generally determined by directly determining the radio interference signal is coupled with the radio frequency signal of the communication network through a direct coupling or indirect coupling mode due to at least one of interference conditions such as co-frequency interference, adjacent channel interference, out-of-band interference, intermodulation interference, blocking interference and the like in the transmission process after the radio frequency signal is transmitted.

The signal compensation processing mode can be as follows: when the electronic device resides in the network communication network, the electronic device can generally acquire signal characteristics corresponding to a standard radio frequency signal (a radio frequency signal corresponding to the absence of signal interference) of the communication network, such as a phase, a frequency, a bandwidth and the like, that is, when the electronic device processes, the electronic device can construct a compensator based on the signal characteristics of the standard radio frequency signal and set parameters of the compensator, and compensate the frequency band of the radio frequency signal through the compensator, so that the relevant frequency band part of the radio frequency signal can be compensated and filtered through a frequency band compensation means, or a majority of the range of the radio frequency signal corresponding to the radio frequency band is removed, so that a reference signal frequency band with high interference weight after the supplement processing is obtained, and then the reference signal frequency band is analyzed, so that a first sub-frequency band matched with the reference signal frequency band is determined in at least one sub-frequency band contained in the target frequency band range. The first sub-band is now the interfered band. The matching may be understood that the reference signal frequency band falls within the range of the first sub-frequency band, and further, when the reference signal frequency band falls within the range of a plurality of first sub-frequency bands at the same time, the number of the first sub-frequency bands may be a plurality of, and the determination of whether the plurality of first sub-frequency bands are interference frequency bands may be implemented by the same determination method.

The signal compensation processing mode can be as follows: the electronic device can pre-construct a compensator based on signal characteristics of standard radio frequency signals and set phase compensation parameters of the compensator, the compensator compensates phases of the radio frequency signals so as to realize the effect of frequency band compensation, in practical application, the compensator processes interference signals coupled into the radio frequency signals, and the purpose of the processing is to weaken specific gravity of initial radio frequency signals transmitted by a communication network in actual radio frequency signals, so that repeated parts corresponding to radio frequency bands of the initial radio frequency signals and the radio frequency bands of the interference signals are highlighted; the compensator may be a repetitive controller, so as to calculate noise and environmental noise of the interference signal, and weaken the specific gravity of the initial rf signal in the actual rf signal by highlighting noise components (associated with the frequency band of the interference signal) in the loop through low-pass/high-pass components, and when the specific gravity of the rf signal is low, it is unnecessary to consider the actual rf signal when determining the first sub-frequency band corresponding to the signal frequency band, so that the first sub-frequency band corresponding to the interference signal can be accurately determined. After the signal frequency band is subjected to signal compensation processing so as to obtain a reference signal frequency band, the electronic equipment determines a first sub-frequency band matched with the reference signal frequency band in at least one sub-frequency band contained in the target frequency band range. The first sub-band is now the interfered band. The matching may be understood that the reference signal frequency band falls within the range of the first sub-frequency band, and further, when the reference signal frequency band falls within the range of a plurality of first sub-frequency bands at the same time, the number of the first sub-frequency bands may be a plurality of, and the determination of whether the plurality of first sub-frequency bands are interference frequency bands may be implemented by the same determination method.

The signal compensation processing mode can be as follows: the electronic device may perform down-conversion processing on signal characteristics (such as signal waveforms, amplitudes, phases, etc.) corresponding to the radio frequency signal in the signal frequency band, where a common down-conversion manner includes, but is not limited to, fitting one or more of real frequency mixing down-conversion, complex frequency mixing down-conversion, and frequency conversion by bandpass, and after the down-conversion processing, reducing a carrier frequency of the signal in the signal frequency band or directly removing the carrier frequency, so as to weaken a specific gravity of the initial radio frequency signal in the actual radio frequency signal, and when the specific gravity of the radio frequency signal is lower, thereby, when determining the first sub-frequency band corresponding to the signal frequency band, no consideration is required for the actual radio frequency signal, and thus, the first sub-frequency band corresponding to the interference signal can be accurately determined. After the signal frequency band is subjected to signal compensation processing so as to obtain a reference signal frequency band, the electronic equipment determines a first sub-frequency band matched with the reference signal frequency band in at least one sub-frequency band contained in the target frequency band range. The first sub-band is now the interfered band.

Step S204: and determining an interfered frequency band existing in the signal frequency band based on the interference judgment information corresponding to the first sub-frequency band.

Specifically, through the steps, the electronic device can primarily screen the range corresponding to the interference frequency band in which the emergent frequency signal exists, and the electronic device can combine the interference judgment information corresponding to the preset first sub-frequency band to further judge the first sub-frequency band based on the interference judgment information.

In a specific implementation scenario, an electronic device may obtain a spectrum threshold of the first sub-band, and may determine a signal spectrum of the reference signal band on the first sub-band. A decision is then made as to whether the first sub-band is an interfering band based on the signal spectrum and the spectrum threshold. In general, the waveform corresponding to the radio frequency signal in the signal spectrum is continuous, the signal spectrum is a function taking frequency as an independent variable, the value of the spectrum at each frequency point is a complex number, the electronic device can determine whether a target signal spectrum higher than the spectrum threshold exists in the signal spectrum, that is, whether an instantaneous frequency value is greater than the spectrum threshold exists, further, when the target signal spectrum exists in the signal spectrum, the electronic device determines the first sub-frequency band as an interfered frequency band existing in the signal frequency band.

Step S205: and carrying out frequency sweep on the at least one preset frequency band range to generate a frequency band sequence.

In a possible implementation, when the electronic device scans the at least one preset frequency band range, the electronic device scans each preset frequency band range from the preset frequency band range with a low frequency band one by one, usually in the order of the frequency bands. The electronic device may further scan the other frequency bands sequentially from the first sub-band, that is, from the boundary point of the first sub-band as a reference, where the scanning order may be to scan forward from the upper boundary point or scan backward from the lower boundary point.

In a possible implementation manner, because the radio frequency signal determined by the electronic device belongs to the target frequency band range and the interference frequency band only belongs to a part of the target frequency band range, the electronic device may scan other non-first sub-frequency bands in the target frequency band range, for example, determine a second sub-frequency band adjacent to the first sub-frequency band in the target frequency band range, and then sweep the frequency of at least one sub-frequency band included in the target frequency band range by using the second sub-frequency band as a reference, and during the scanning, detect the frequency band quality on each sub-frequency band at the same time, so as to generate a frequency band sequence including the frequency band quality corresponding to each sub-frequency band. Then, the electronic device may select a target frequency band with good frequency band quality based on the frequency band sequence, for example, select a sub-frequency band with the best frequency band quality as the target frequency band.

Step S206: and determining a target frequency band outside the interfered frequency band based on the frequency band sequence, and reporting the target frequency band to the communication network.

Specifically, the electronic device may report the frequency selection indication information to the communication network in the form of the frequency selection indication information with respect to the target frequency band and the first sub-frequency band (i.e., the frequency band determined to be interfered) except the frequency band determined to be interfered, and may report the frequency selection indication information to the communication network based on the target frequency band during reporting.

The following will explain the signal interference processing method executed by the electronic device in detail in combination with the actual application scenario of the electronic device according to the embodiment of the present application, specifically as follows:

as shown in fig. 4, fig. 4 is a view of an actual application scenario of signal interference processing, when a network device in a communication network transmits a radio frequency signal in a signal transmission time, for example, the network device in the communication network transmits the radio frequency signal in a beam mode, an electronic device for signal reception may receive the radio frequency signal transmitted by the communication network through an antenna included therein, perform preliminary processing on the radio frequency signal with a phase shifter, a converter and an FFT (fourier transform), then determine a signal frequency band of the radio frequency signal and a target frequency band range corresponding to the signal frequency band, and then perform signal compensation processing on the signal frequency band by a compensator to obtain a reference signal frequency band; and then determining a first sub-frequency band matched with the reference signal frequency band in at least one sub-frequency band contained in the target frequency band range by a frequency selecting part contained in the electronic equipment.

In addition, the signal interference processing device and the signal interference processing method embodiment provided in the foregoing embodiments belong to the same concept, which embody the implementation process in detail with reference to the method embodiment, and are not repeated here.

The foregoing embodiment numbers of the present application are merely for the purpose of description, and do not represent the advantages or disadvantages of the embodiments.

Referring to fig. 10, a block diagram of an electronic device according to an exemplary embodiment of the present application is shown. The electronic device of the present application may include one or more of the following components: processor 110, memory 120, input device 130, output device 140, and bus 150. The processor 110, the memory 120, the input device 130, and the output device 140 may be connected by a bus 150.

Processor 110 may include one or more processing cores. The processor 110 utilizes various interfaces and lines to connect various portions of the overall electronic device, perform various functions of the electronic device 100, and process data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120, and invoking data stored in the memory 120. Alternatively, the processor 110 may be implemented in at least one hardware form of digital signal processing (digital signal processing, DSP), field-programmable gate array (field-programmable gate array, FPGA), programmable logic array (programmable logic Array, PLA). The processor 110 may integrate one or a combination of several of a central processing unit (central processing unit, CPU), an image processor (graphics processing unit, GPU), and a modem, etc. The CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for being responsible for rendering and drawing of display content; the modem is used to handle wireless communications. It will be appreciated that the modem may not be integrated into the processor 110 and may be implemented solely by a single communication chip.

The memory 120 may include a random access memory (random Access Memory, RAM) or a read-only memory (ROM). Optionally, the memory 120 includes a non-transitory computer readable medium (non-transitory computer-readable storage medium). Memory 120 may be used to store instructions, programs, code, sets of codes, or sets of instructions. The memory 120 may include a stored program area and a stored data area, wherein the stored program area may store instructions for implementing an operating system, which may be an Android (Android) system, including an Android system-based deep development system, an IOS system developed by apple corporation, including an IOS system-based deep development system, or other systems, instructions for implementing at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing various method embodiments described below, and the like. The storage data area may also store data created by the electronic device in use, such as phonebooks, audiovisual data, chat log data, and the like.

Referring to FIG. 11, the memory 120 may be divided into an operating system space in which the operating system runs and a user space in which native and third party applications run. In order to ensure that different third party application programs can achieve better operation effects, the operating system allocates corresponding system resources for the different third party application programs. However, the requirements of different application scenarios in the same third party application program on system resources are different, for example, under the local resource loading scenario, the third party application program has higher requirement on the disk reading speed; in the animation rendering scene, the third party application program has higher requirements on the GPU performance. The operating system and the third party application program are mutually independent, and the operating system often cannot timely sense the current application scene of the third party application program, so that the operating system cannot perform targeted system resource adaptation according to the specific application scene of the third party application program.

In order to enable the operating system to distinguish specific application scenes of the third-party application program, data communication between the third-party application program and the operating system needs to be communicated, so that the operating system can acquire current scene information of the third-party application program at any time, and targeted system resource adaptation is performed based on the current scene.

Taking an operating system as an Android system as an example, as shown in fig. 12, a program and data stored in the memory 120 may be stored in the memory 120 with a Linux kernel layer 320, a system runtime library layer 340, an application framework layer 360 and an application layer 380, where the Linux kernel layer 320, the system runtime library layer 340 and the application framework layer 360 belong to an operating system space, and the application layer 380 belongs to a user space. The Linux kernel layer 320 provides the underlying drivers for various hardware of the electronic device, such as display drivers, audio drivers, camera drivers, bluetooth drivers, wi-Fi drivers, power management, and the like. The system runtime layer 340 provides the main feature support for the Android system through some C/c++ libraries. For example, the SQLite library provides support for databases, the OpenGL/ES library provides support for 3D graphics, the Webkit library provides support for browser kernels, and the like. Also provided in the system runtime library layer 340 is a An Zhuoyun runtime library (Android run) which provides mainly some core libraries that can allow developers to write Android applications using the Java language. The application framework layer 360 provides various APIs that may be used in building applications, which developers can also build their own applications by using, for example, campaign management, window management, view management, notification management, content provider, package management, call management, resource management, signal interference handling management. At least one application program is running in the application layer 380, and these application programs may be native application programs of the operating system, such as a contact program, a short message program, a clock program, a camera application, etc.; and can also be a third party application program developed by a third party developer, such as a game application program, an instant messaging program, a photo beautification program, a signal interference processing program and the like.

Taking an operating system as an IOS system as an example, the program and data stored in the memory 120 are shown in fig. 13, the IOS system includes: core operating system layer 420 (Core OS layer), core service layer 440 (Core Services layer), media layer 460 (Media layer), and touchable layer 480 (Cocoa Touch Layer). The core operating system layer 420 includes an operating system kernel, drivers, and underlying program frameworks that provide more hardware-like functionality for use by the program frameworks at the core services layer 440. The core services layer 440 provides system services and/or program frameworks required by the application, such as a Foundation (Foundation) framework, an account framework, an advertisement framework, a data storage framework, a network connection framework, a geographic location framework, a sports framework, and the like. The media layer 460 provides an interface for applications related to audiovisual aspects, such as a graphics-image related interface, an audio technology related interface, a video technology related interface, an audio video transmission technology wireless play (AirPlay) interface, and so forth. The touchable layer 480 provides various commonly used interface-related frameworks for application development, with the touchable layer 480 being responsible for user touch interactions on the electronic device. Such as a local notification service, a remote push service, an advertisement framework, a game tool framework, a message User Interface (UI) framework, a User Interface UIKit framework, a map framework, and so forth.

Among the frameworks illustrated in fig. 13, frameworks related to most applications include, but are not limited to: the infrastructure in core services layer 440 and the UIKit framework in touchable layer 480. The infrastructure provides many basic object classes and data types, providing the most basic system services for all applications, independent of the UI. While the class provided by the UIKit framework is a basic UI class library for creating touch-based user interfaces, iOS applications can provide UIs based on the UIKit framework, so it provides the infrastructure for applications to build user interfaces, draw, process and user interaction events, respond to gestures, and so on.
