The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The present application will be described in detail with reference to specific examples.
In one embodiment, as shown in fig. 1, an antenna parameter configuration method is specifically proposed, which can be implemented by means of a computer program and can run on an antenna parameter configuration device based on the von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application.
Specifically, the antenna parameter configuration method includes:
step S101: and when the card to be read and written is detected in the NFC reader-writer mode, identifying the card identification corresponding to the card to be read and written.
The NFC (Near-field-communication) working modes mainly include three types: a reader/writer mode, a card emulation mode, and a peer-to-peer mode. In the application, the terminal is mainly applied to an NFC reader-writer mode, and parameter configuration of an NFC antenna is achieved.
For the terminal, when a user on the terminal inputs an NFC reader start instruction for the NFC reader mode, the terminal may respond to the NFC reader start instruction, so as to start the NFC reader mode, operate in the NFC reader mode, and perform detection on a card to be read and written.
Specifically, the NFC reader start instruction may be triggered by the user based on selection of an NFC service (such as an NFC application and an NFC plug-in) on the terminal, and if the user starts and runs an application program for reading a bus card on the terminal, an NFC module or an NFC chip included in the terminal operates in an NFC card reader mode at this time.
The terminal having the NFC function can operate in a reader/writer mode for an NFC tag, a peer-to-peer mode for other NFC devices, and a card emulation mode for other NFC readers, and terminals based on different NFC standards support different data transmission rates of 106kbps (kilobits per second), 212kbps, and 424 kbps. Two communication modes are supported between the terminal and corresponding entities (such as cards to be detected and other NFC equipment): an active mode (such as a point-to-point mode) in which the communication initiating device and the target communication device are both powered by themselves and alternately transmit data; the method comprises the steps that a communication initiating device generates a wireless signal and supplies power to a target communication device through an electromagnetic field, and the target communication device responds to a passive mode (such as an NFC reader mode and a card simulation mode) of the communication initiating device through modulation of the existing electromagnetic field, wherein in the application, a terminal in the NFC reader mode is started, the communication mode is generally passive communication in active communication and passive communication (such as NFC-A, POLL and passive communication), at the moment, the terminal with the NFC function works in the NFC reader mode, and the NFC-A is a proper term in NFC specification
Further, in the reader/writer mode, a terminal (e.g., a mobile phone supporting NFC communication) serving as an NFC reader/writer is close to a card to be read/written, where the card to be read/written may be regarded as a passive NFC tag and generates a detection signal, an antenna of the NFC tag captures electric energy from an electromagnetic field of the detection signal to supply power to a memory, and transmits data stored in the memory to the terminal serving as the NFC reader/writer by modulating the electromagnetic field. Because the passive NFC tag (namely the card to be read and written in the application) can assist the terminal to complete the reading and writing of the card to be read and written only by the antenna and the corresponding storage device without an additional battery.
In addition, in this application, the card identifier is used to uniquely represent a certain type of card to be read and written or a card to be read and written corresponding to a certain single entity, and the card identifier may be represented in the form of numbers, characters, character strings, and the like.
Explaining the detailed process of identifying the card identification corresponding to the card to be read and written by the terminal as follows:
specifically, in a scenario of performing card data reading and writing by using the NFC technology, a device supporting NFC is generally referred to as a device in which a host device starts NFC communication, and is also referred to as an NFC host device, and a radio frequency field (i.e., RF) is provided in the whole communication process. Generally, one transmission speed of 106kbps, 212kbps or 424kbps can be selected for reading and writing data, a detection signal (which can be understood as a radio frequency signal) is emitted to the outside through an included NFC antenna, a radio frequency field is provided based on the continuously emitted radio frequency signal, when a card to be read and written is identified, if the card to be read and written is close to a terminal at the moment, so as to enter the range of the radio frequency field of the terminal, the terminal can identify the card to be read and written, and card information of the card to be read and written can be obtained, so that the card identification of the card to be read and written is determined. In addition, in the whole process of the card to be read and written as the NFC tag, a radio frequency field does not need to be generated, and a load modulation technology is used, so that corresponding NFC communication data (such as an induction command, card information, and the like) can be transmitted back to the host device, that is, the terminal, at the same transmission speed.
In a specific embodiment, the NFC operating mode is divided into a passive mode and an active mode. The passive mode is as shown in fig. 2, fig. 2 is a scene schematic diagram of a terminal operating in the NFC passive mode, where an NFC initiator is a terminal (i.e., a master device), the terminal is used as the master device to continuously transmit a radio frequency signal by using energy of a contained power supply component (e.g., an internal battery) to provide a radio frequency field (i.e., RF), and if a card to be read and written approaches the terminal and enters a range of the radio frequency field of the terminal, the NFC card induces the radio frequency signal sent by an NFC card reader to generate a corresponding electromagnetic wave signal in the radio frequency field, so that the terminal can recognize the card to be read and written, and the terminal can determine to detect the card to be read and written based on the electromagnetic wave signal by controlling a contained NFC antenna to collect the electromagnetic wave signal, and further obtain card information of the card to be read and written to determine an identification card of the card to be read and written, in practical applications, the NFC card does not generate a radio frequency field, and transmits response data (such as card information and corresponding sensing commands) back to the host device at the same speed by using a load modulation technique. In the passive mode, when the NFC master device-terminal can detect the card to be read and written, the card information corresponding to the card to be read and written is acquired, so that the terminal can analyze the card information conveniently, and can determine the card identifier of the card to be read and written.
In some embodiments, the obtained card information of the card to be read/written may be understood as a signal information, and in some embodiments, the signal information may also be characterized by a signal characteristic; in addition, the card information may be physical signal information, or may be data information stored in a memory of the card to be read and written.
Wherein physical signals can be understood as:
the terminal can generate induction with a radio frequency signal sent by an NFC card reader based on an NFC card, so that a corresponding electromagnetic wave signal is generated in a radio frequency field, the electromagnetic wave signal can be a signal characteristic which does not contain data information stored in a memory in the card to be read and written, namely, for the terminal, the detailed information of the card to be read and written can be identified only by physical characteristics of the electromagnetic wave signal, such as circuit parameter (current, voltage and the like) characteristics, amplitude-frequency characteristics, transmission rate characteristics, magnetic field signal characteristics, NFC label protocol characteristics and other physical characteristics, such as card identification of the card to be read and written is determined, and the card identification can be the unique representation of the card type, card ID and the like of the card to be read and written.
The data information stored in the memory of the card to be read/written can be understood as:
the data information is information of the NFC card to be read and written, including the capacity, the type, the creating time, the card identification, the data abstract, the check code of the data, the data name and the like of the NFC card.
The designated range is a range in which the NFC card and the NFC card reader can implement near field communication, and the designated range is a range specified by the near field communication technology, for example, NFC operates at 13.56MHZ, and requires a communication distance within a range of 20 cm.
The storage space of the NFC card is divided into a boot area, a data storage page area, a data description area and a data area.
The boot area is used for storing basic information of the NFC card, and the basic information comprises information such as capacity, type, creation time, card identification, data abstract, data check code and data name of the NFC card.
The data storage page area indicates the use condition of the storage page of the NFC card and represents a linked list structure of the page stored by the file data;
and the data description area is used for describing information of the stored files, each item of the data description area corresponds to the file description of one file stored in the card, and the content of the data description area is the file information and the initial page number of the file.
And the data area is used for storing written data contents and occupies most of the pages of the FLASH storage area.
In practical implementation, the terminal provides a radio frequency field by using energy of a contained power supply component (such as an internal battery), when a radio frequency range corresponding to the radio frequency field can cover a card to be read and written, the card to be read and written can receive a radio frequency signal of the terminal, at this time, the target device feeds back response data (such as part or all of stored data) to the terminal in the form of an electromagnetic wave signal at the same speed by using a load modulation technology, and the terminal can analyze card data carried by the electromagnetic wave signal and determine a card identifier corresponding to the card to be read and written.
Step S102: and determining first configuration parameters of the NFC antenna based on the card identification.
Specifically, the terminal is pre-established with a mapping relationship between at least one reference card identifier and configuration parameters, the mapping relationship may be represented in the form of a linear list, a parameter set, a parameter configuration distribution map, and the like, and in the related art, in the performance indexes of the NFC card reader, the configuration parameters such as the similar receiving sensitivity and the similar transmitting field strength indexes have been specified in ISO/IEC 10373-6. Because the simulated return of the NFC card reader generally adopts a passive load modulation mode, the return signal strength is in positive correlation with the configuration parameters of the terminal in the card reader mode. Therefore, the sensitivity of reading and writing the card to be read and written is usually improved by increasing the value corresponding to each configuration parameter of the card reader as much as possible, for example, the NFC antenna is controlled to work by the maximum value corresponding to each configuration parameter, so that the communication sensing distance of NFC can be increased as much as possible, and the card to be read and written can be identified. In the application, it is considered that the power consumption of the terminal is undoubtedly wasted by adopting the method, and in an actual application environment, when a scene of the NFC read-write card is involved, a user usually attaches the "card to be read-written" to the terminal, so that higher configuration parameters are not required to be maintained actually.
In this application, when the terminal detects a card to be read and written in the NFC reader mode, the terminal may configure a configuration parameter of a current NFC antenna in a process of reading and writing the "card to be read and written", so as to select an appropriate configuration parameter to control the NFC antenna to operate, it may be understood that the determined first configuration parameter may be determined based on a working threshold value that ensures that the card to be read and written can be read and written, for example, the first configuration parameter may be the working threshold value, and for example, a difference between the first configuration parameter and the working threshold value is smaller than a certain threshold value.
Optionally, the mapping relationship between the reference card identifier and the configuration parameter may be a configuration parameter with lower power consumption determined by debugging the configuration parameter of the type of reference card when the terminal identifies the type of reference card for the first time; the terminal can acquire the data from a cloud server maintaining the type of reference card based on a big data technology, the cloud server acquires a large amount of sample data in an actual NFC read-write scene in advance, and the sample data is analyzed in a mathematical statistics mode so as to determine the mapping relation between the reference card identification and the configuration parameters.
Further, configuration parameters of the NFC antenna are used for determining an operating state of the NFC, and different configuration parameters are different from each other in performance indexes of the NFC antenna, where the configuration parameters include but are not limited to resonant frequency characteristic parameters; a quality factor characteristic parameter; matching impedance Z characteristic parameters; inductance L characteristic parameters; sensing a distance S characteristic parameter; modulating a depth characteristic parameter; field intensity characteristic parameters; a signal integrity characteristic parameter; power characteristic parameters, etc. In addition, the first configuration parameter is a mapping relationship between a terminal country reference card identifier and a configuration parameter, and the configuration parameter corresponding to the card identifier is determined, that is, the first configuration parameter.
Step S103: and configuring the NFC antenna based on the first configuration parameter, and reading and writing the card to be read and written by adopting the configured NFC antenna.
Specifically, after the terminal determines the first configuration parameter of the NFC antenna based on the card identifier, each parameter index of the current NFC antenna is adjusted according to each parameter value corresponding to the first configuration parameter, for example, each parameter index of the NFC antenna is updated to each parameter value corresponding to the first configuration parameter, for example, the modulation depth index is updated to the modulation depth characteristic parameter indicated by the first configuration parameter, the inductance L index is updated to the inductance L characteristic parameter indicated by the first configuration parameter, and the like.
Specifically, after the terminal completes configuration of the NFC antenna based on the first configuration parameter, the card to be read and written may be read and written by using the configured NFC antenna, so as to perform corresponding read and write operations on related data information in the card to be read and written. The terminal can comprise a corresponding read-write module and is used for executing read-write operation or write-write operation on the first NFC card according to the basic information and the read-write instruction of the card to be read and written.
Specifically, the read-write module at least comprises a read-write management unit, a physical addressing IO management unit, a read queue and a write queue. The read-write management unit is used for managing the read-write operation of the data. And the physical addressing IO management unit is used for converting a physical addressing mode into a file storage management mode. The read queue and the write queue are respectively used for reading and writing data. And the read-write management unit, the physical addressing IO management unit, the read queue and the write queue in the read-write module are matched with each other, so that the data reading operation or the data writing operation is executed on the first NFC card according to the basic information and the read-write instruction.
In the embodiment of the application, when a terminal detects a card to be read and written in an NFC reader-writer mode, the terminal identifies a card identifier corresponding to the card to be read and written, determines a first configuration parameter of an NFC antenna based on the card identifier, configures the NFC antenna based on the first configuration parameter, and reads and writes the card to be read and written by adopting the configured NFC antenna. The terminal does not directly read and write the card to be read and written when detecting the card to be read and written according to the default configuration parameters, but adjusts the configuration parameters of the NFC antenna based on the card identification of the card to be read and written, so as to avoid the problem of high power consumption of the card to be read and written when reading and writing according to the default configuration parameters.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating another embodiment of an antenna parameter configuration method according to the present application. Specifically, the method comprises the following steps:
step S201: when a card to be read and written is detected in an NFC reader-writer mode, acquiring an electromagnetic wave signal generated when the card to be read and written is detected;
according to some embodiments, in the NFC reader mode, a terminal (e.g., a mobile phone supporting NFC communication) serving as an NFC reader is close to a card to be read and written, where the card to be read and written may be regarded as a passive NFC tag, and generates a detection signal when the NFC reader mode is turned on, and generates a corresponding radio frequency field (which may be understood as an electromagnetic field) through the detection signal continuously emitted to the outside, if the card to be read and written enters the range of the radio frequency field, the card to be read and written induces a radio frequency signal emitted by the terminal serving as the NFC reader, an antenna (e.g., an antenna coil) of the NFC tag captures electric energy from the electromagnetic field of the detection signal to power a memory, and generates a corresponding electromagnetic wave signal in the radio frequency field by modulating the electromagnetic field, so that the terminal recognizes the card to be read and written, and the terminal collects the electromagnetic wave signal by controlling an included NFC antenna, the passive NFC tag (i.e., the card to be read and written in the present application) can assist the terminal to complete reading and writing of the card to be read and written only by the antenna and the corresponding memory device without an additional battery.
Step S202: and identifying the electromagnetic wave signals, and determining signal characteristics corresponding to the electromagnetic wave signals.
The signal characteristics include at least one of circuit characteristics, communication transmission characteristics, and NFC protocol characteristics.
The circuit characteristics can be understood as circuit parameters for feeding back the current circuit state of the NFC antenna, the circuit parameters include but are not limited to voltage parameters, current parameters, inductance L parameters and the like, different types or different cards to be read and written can correspondingly generate different circuit parameters when being detected by a terminal, and the cards to be read and written can be identified uniquely based on the circuit characteristics.
The communication transmission characteristics can be understood as feedback of transmission parameters such as transmission rate, modulation depth, transmission power and the like when the card to be read and written and the terminal perform NFC data interaction, it can be understood that different types or different cards to be read and written correspond to different transmission parameters when being detected by the terminal, and based on the transmission parameters, the card to be read and written can be uniquely identified, for example, the card to be read and written of different types, the data transmission rates are mostly inconsistent.
The characteristics of the NFC protocol may be understood that different protocols used by different types of cards to be read and written are different, and may be further identified based on the protocol parameters of the feedback NFC protocol, for example, the characteristics may be a protocol identifier, a protocol frame digest, a check code of a protocol frame, and the like.
The terminal can generally perform signal identification on the electromagnetic wave signal generated when acquiring the card to be read and written, for example, the signal characteristics corresponding to the electromagnetic wave signal can be determined by performing identification means such as analog-to-digital conversion on the electromagnetic wave signal, performing spectrum analysis on the electromagnetic wave signal, and performing gaussian filtering on the electromagnetic wave signal.
Step S203: and determining a target feature matched with the signal feature, and taking a target identifier corresponding to the target feature as a card identifier corresponding to the card to be read and written.
According to some embodiments, the terminal previously represents the identifier mapping relationship between the corresponding card identifier and the reference signal feature corresponding to the electromagnetic wave signal to be read and written, and the identifier mapping relationship may be in the form of a linear list, a parameter set, a parameter configuration distribution map, and the like.
Wherein determining the target feature that matches the signal feature may be:
in practical application, the terminal stores reference signal characteristics corresponding to each reference card identifier in advance, and the reference signal characteristics include, but are not limited to, all types of reference parameters corresponding to at least one of circuit characteristics, communication transmission characteristics and NFC protocol characteristics. In the way of matching each reference signal feature with the target feature: calculating similarity between each reference signal feature and a target feature, or calculating similarity distance between each reference signal feature and a target feature; may be calculating difference feature information for each of the reference signal features and target features, and then ranking or scoring based on the difference feature information; it may also be determined whether the target feature falls within a corresponding reference signal feature range, and so on.
Specifically, after obtaining the analysis processing result corresponding to each reference signal feature according to the matching processing mode, the terminal evaluates the analysis processing result according to a preset evaluation rule, and when the analysis processing result meets the set matching evaluation requirement, the terminal can determine the target feature matched with the signal feature, that is, the current reference signal feature is used as the target feature.
Optionally, when the analysis processing result is based on the similarity between the reference signal feature and the target feature, the evaluation rule may be to set a similarity threshold, and when the similarity of the analysis processing result reaches the similarity threshold, the terminal may determine the target feature matched with the signal feature, that is, the current reference signal feature is used as the target feature.
Optionally, when the analysis processing result is based on the similarity distance between the reference signal feature and the target feature, the evaluation rule may be to set a similarity distance threshold, and when the similarity of the analysis processing result reaches the similarity distance threshold, the terminal may determine the target feature matched with the signal feature, that is, take the current reference signal feature as the target feature.
Optionally, when the analysis processing result is based on the rating or the score of the difference feature information between the reference signal feature and the target feature, the evaluation rule may be to set a similarity level threshold or a similarity score threshold, and when the similarity level of the analysis processing result reaches the similarity level threshold or the similarity score reaches the similarity score threshold, the terminal may determine the target feature matched with the signal feature, that is, the current reference signal feature is used as the target feature.
Optionally, the terminal may determine, for the reference signal feature, whether the target parameter corresponding to the target signal feature falls within the reference parameter range of the same type corresponding to the reference signal feature. For example, the target parameter corresponding to the target signal feature may be represented by a numerical type (e.g., the parameter is represented by a numerical value), and the terminal determines whether the numerical value falls within a reference parameter range of the same type, for example, the numerical value is greater than a certain numerical threshold or less than a certain numerical threshold, so as to determine the target feature matching the signal feature, that is, the current reference signal feature is used as the target feature.
Step S204: and determining a reference configuration parameter corresponding to the card identifier according to a mapping relation between a preset reference identifier and the configuration parameter, and taking the reference configuration parameter as a first configuration parameter of the NFC antenna.
Specifically, after determining the target feature matched with the signal feature and taking the target identifier corresponding to the target feature as the card identifier corresponding to the card to be read and written, the terminal may determine the reference configuration parameter corresponding to the card identifier according to a unique mapping relationship between a preset reference identifier and the configuration parameter, and take the reference configuration parameter as the first configuration parameter of the NFC antenna.
Step S205: acquiring a historical debugging record of a reference card corresponding to the card identification, and acquiring a sensitivity reference value corresponding to the card identification; determining the first configuration parameter for the included NFC antenna based on the historical commissioning record and the sensitivity reference value.
The history debugging record can be understood as follows in the application: carrying out sensitivity debugging on reference cards corresponding to the same type of card identification in advance, setting a plurality of groups of different types of configuration debugging parameters, and then acquiring an actual sensitivity value under an actual application environment, wherein the configuration debugging parameters include but are not limited to resonant frequency test parameters; quality factor test parameters; matching impedance Z test parameters; inductance L test parameters; sensing a distance S test parameter; modulating depth test parameters; testing parameters of field intensity; a signal integrity test parameter; power test parameters, and the like.
The sensitivity reference value is a threshold value of the sensitivity of the card corresponding to the card identifier, and when the actual sensitivity is not less than the threshold value, the NFC reader-writer can perform normal reading and writing on the card corresponding to the card identifier. Further, the sensitivity reference value may be a calibration value preset by the terminal, or a calibration value custom-set by a user at a later stage, or a calibration value specified by an NFC communication protocol adopted by the card corresponding to the card identifier.
In specific implementation, the terminal only needs to search the actual sensitivity value matched with the sensitivity reference value in the historical debugging record, and then obtains a group of configuration debugging parameters adopted during test debugging corresponding to the actual sensitivity value, namely the reference configuration parameters; so that the terminal can use this reference configuration parameter as said first configuration parameter for the included NFC antenna.
Optionally, the historical debugging record may be obtained by the terminal from a local storage space; may be obtained from a cloud server.
Step S206: and when the second configuration parameter of the NFC antenna is not matched with the first configuration parameter, configuring the NFC antenna, and reading and writing the card to be read and written by adopting the configured NFC antenna.
The second configuration parameter is a current configuration parameter of an NFC antenna included in the terminal. In this application, configuring the NFC antenna based on the first configuration parameter may refer to determining whether the current configuration parameter needs to be updated.
Specifically, the terminal may obtain a target sensitivity corresponding to the card to be read and written and a reference sensitivity corresponding to the card identifier, where the target sensitivity is a sensitivity of the card to be read and written detected when the NFC antenna operates with the second configuration parameter;
in practical application, whether the current configuration parameters need to be updated or not is measured mainly based on the sensitivity value of the terminal aiming at the card to be read and written, namely the target sensitivity, in the NFC reader-writer mode; the reference sensitivity is a threshold value of the sensitivity of the card corresponding to the card identifier, and when the actual sensitivity is not less than the threshold value, the NFC reader can perform normal reading and writing on the card corresponding to the card identifier. In practical application, because a terminal usually works with larger configuration parameters and externally transmits a detection signal, when a card to be read and written is detected, the measured actual sensitivity of the card to be read and written is generally higher, mainly for ensuring the maximum NFC communication distance so as to quickly identify the card to be read and written, in the actual user operation process, a user can continuously operate the card to be read and written to be close to the terminal, and the terminal can measure the current sensitivity corresponding to the card to be read and written, so that the target sensitivity is obtained;
then judging whether the target sensitivity is matched with the reference sensitivity, and when the target sensitivity is not matched with the reference sensitivity, the terminal determines that the second configuration parameter of the NFC antenna is not matched with the first configuration parameter; if not, the current configuration parameter is usually too high, and the terminal updates the second configuration parameter of the NFC antenna to the first configuration parameter.
Further, the above-mentioned judging whether the target sensitivity matches with the reference sensitivity may be:
the terminal calculates the sensitivity difference value of the target sensitivity and the reference sensitivity;
and when the sensitivity difference is larger than a difference threshold, the terminal determines that the target sensitivity is not matched with the reference sensitivity.
In the embodiment of the application, when a terminal detects a card to be read and written in an NFC reader-writer mode, the terminal identifies a card identifier corresponding to the card to be read and written, determines a first configuration parameter of an NFC antenna based on the card identifier, configures the NFC antenna based on the first configuration parameter, and reads and writes the card to be read and written by adopting the configured NFC antenna. The terminal does not directly read and write the card to be read and written when detecting the card to be read and written according to the default configuration parameters, but adjusts the configuration parameters of the NFC antenna based on the card identification of the card to be read and written, so as to avoid the problem of high power consumption of the card to be read and written when reading and writing according to the default configuration parameters, and through combining with practical application environments, when detecting the card to be read and written, the card to be read and written can be close to the NFC antenna contained in the terminal (if a user can operate the card to be read and written and can be close to the terminal), at the moment, the power consumption resources of the terminal can be wasted by using the default configuration parameters with higher power consumption, the power consumption can be greatly reduced by adopting the antenna parameter configuration method, the electric quantity of the terminal can be saved, and the optimal performance of the terminal in terms of NFC can be realized; and real-time adjustment before reading and writing is carried out according to the card identification (such as the card type) of the card to be read and written, so that the problem of mistaken reading due to overhigh sensitivity can be avoided, the application scene in an NFC reader-writer mode is optimized, and the antenna parameter adjustment is more intelligent.

Referring to fig. 11, a block diagram of an electronic device according to an exemplary embodiment of the present application is shown. The electronic device in the present application may comprise one or more of the following components: a processor 110, a memory 120, an input device 130, an output device 140, and a bus 150. The processor 110, memory 120, input device 130, and output device 140 may be connected by a bus 150.

The processor 110 connects various parts within the overall electronic device using various interfaces and lines, and performs various functions of the electronic device 100 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120 and calling data stored in the memory 120. Alternatively, the processor 110 may be implemented in hardware using at least one of Digital Signal Processing (DSP), field-programmable gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 may integrate one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing display content; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 110, but may be implemented by a communication chip.

Referring to fig. 12, the memory 120 may be divided into an operating system space, where an operating system is run, and a user space, where native and third-party applications are run. In order to ensure that different third-party application programs can achieve a better operation effect, 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, in a local resource loading scenario, the third-party application program has a higher requirement on the disk reading speed; in the animation rendering scene, the third-party application program has a high requirement on the performance of the GPU. The operating system and the third-party application program are independent from each other, and the operating system cannot sense the current application scene of the third-party application program in time, 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 a specific application scenario of the third-party application program, data communication between the third-party application program and the operating system needs to be opened, so that the operating system can acquire current scenario information of the third-party application program at any time, and further perform targeted system resource adaptation based on the current scenario.
