The background is overlapped and cached while the local video is played in the video application, and the speed of the background cache is about 5MB/s, and in this case, the average discharge current of the electronic equipment exceeds 560mA. The background is overlaid with the cache while the local video is playing in the video class application, and the rate of the background cache is approximately 10MB/s, in which case the average discharge current of the electronic device exceeds 630mA. It is understood that the average discharge current of the electronic device may represent the power consumption of the electronic device. The larger the average discharge current of the electronic device, the greater the power consumption of the electronic device. Accordingly, the greater the power consumption, the more likely the electronic device is to heat, i.e., the temperature rises.

TABLE 3 Table 3

It is understood that the electronic device mentioned in the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an Ultra-Mobile Personal Computer, a UMPC, a netbook, a cellular phone, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), an augmented Reality (Augmented Reality, AR) device, a Virtual Reality (VR) device, an artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) device, a wearable device, a vehicle device, a smart home device, and/or a smart city device. The embodiment of the application does not limit the specific type of the electronic equipment.

Based on the above, and the hardware structure of the electronic device shown in fig. 1, the temperature control scenario in the high-speed uploading state and the temperature control scenario in the high-speed downloading state provided by the present application are described.

Referring to fig. 2, fig. 2 is a schematic diagram of a TX (i.e., transport) link and an RX (i.e., receive) link according to an embodiment of the present application. As shown in fig. 2, the electronic device may include an application processor, a modem, a radio frequency integrated circuit, and an antenna 1. Wherein the application processor and the modem may send data to each other. The radio frequency integrated circuit may include a power amplifier, a low noise amplifier, and an antenna switch. It will be appreciated that the TX link (i.e., the transmit link) and the RX link (i.e., the receive link) of the data transmission may be formed between the above-described modules. The TX link corresponds to a high-speed uploading scene, and the RX link corresponds to a high-speed downloading scene.

In the high-speed uploading scenario, the application processor may transmit data to the modem through Qlink, the modem may convert the received data from a digital signal to an analog signal, and transmit the converted analog signal to the radio frequency integrated circuit, and finally convert the converted analog signal into electromagnetic waves to radiate through the antenna 1. In particular, the analog signal transmitted into the radio frequency integrated circuit may be amplified via a power amplifier and then radiated via the antenna switch and the antenna 1. It is understood that the relevant description of Qlink may refer to the relevant technical document and is not explained here.

In the high-speed downloading scenario, the antenna 1 in the electronic device may receive the electromagnetic wave, then the radio frequency integrated circuit performs filtering, amplifying and other processes on the received electromagnetic wave to obtain a processed signal, and then the processed signal is transmitted to the modem, and accordingly, the modem may convert the processed signal from an analog signal to a digital signal, and finally the digital signal is transmitted to the application processor through Qlink. Specifically, in the process of processing the received electromagnetic wave by the radio frequency integrated circuit, the low noise amplifier in the radio frequency integrated circuit can perform filtering and amplifying processing on the received electromagnetic wave.

In some embodiments of the application, a network protocol stack (e.g., a TCP/IP protocol stack) may be provided in the application processor. Before the application processor sends the data to the modem, the application processor may encapsulate the raw data to obtain a data packet. The application processor then sends the data packet to the modem. It is appreciated that the TCP/IP protocol stack is a ring in the data encapsulation process. In the process of transmitting data between the application processor and the modem, the application processor may encapsulate the original data into a data packet based on the TCP/IP protocol stack and then send the data packet to the modem. In one possible implementation, a buffer status report (Buffer Status Reports, BSR) module in the modem may receive data packets sent by the TCP/IP protocol stack.

In some embodiments of the application, the radio frequency integrated circuit may also include further devices, such as mixers, frequency synthesizers, and the like. The power amplifier, the low noise amplifier and the antenna switch may also not be disposed in the radio frequency integrated circuit, but may be independent of the radio frequency integrated circuit.

It is understood that the network transmission rate referred to in the present application may be the rate at which data is transmitted between the application processor and the modem.

Based on the above temperature control scenario, the following describes a temperature control method provided by the present application.

Referring to fig. 3, fig. 3 is a flowchart of a temperature control method according to an embodiment of the application. The temperature control method may include, but is not limited to, the steps of:

S301: the electronic device determines a current backshell temperature.

It is understood that the electronics can measure the back shell temperature via a temperature sensor. Wherein the back case temperature refers to the temperature of the case behind the electronic device. It will be appreciated that when a user uses the electronic device, the face of the electronic device facing the user is the front face, and the face of the electronic device facing away from the user is the rear face. In the case of an electronic device comprising a display screen, the housing behind the electronic device refers to the housing opposite the display screen of the electronic device. In the case where the electronic device includes a rear camera, the housing behind the electronic device refers to the housing on the side of the electronic device where the rear camera is located.

It will be appreciated that the electronics can measure the backshell temperature via the temperature sensor 180J shown in fig. 1.

In some embodiments of the application, the electronic device determines the current backshell temperature once every first time period. The first duration may be set according to actual needs, which is not limited by the present application. For example, the first duration may be 1 minute.

S302: the electronic device determines whether the current backshell temperature exceeds a temperature threshold.

After the electronic device determines the current back shell temperature, it may be determined whether the current back shell temperature exceeds a temperature threshold. It will be appreciated that the temperature threshold may be set according to actual needs, as the application is not limited in this regard. For example, the temperature threshold may be 43 degrees celsius (°c). For another example, the temperature threshold may be 40 ℃.

S303: the electronic device determines a current network transmission rate.

It can be appreciated that the electronic device can utilize the data statistics interface to count the data flow rate through the network protocol stack in the application processor, which is the current network transmission rate. For example, in the case where the operating system of the electronic device is an android system, the electronic device may utilize the android native data statistics interface to count data flow rates through a network protocol stack in the application processor.

In some embodiments of the application, the electronic device determines the current network transmission rate once every first time period.

S304: the electronic device determines whether the current network transmission rate exceeds a network transmission rate threshold.

After the electronic device determines the current network transmission rate, it may be determined whether the current network transmission rate exceeds a network transmission rate threshold.

It will be appreciated that the network transmission rate threshold may be set according to actual needs, and the application is not limited in this respect. For example, the network transmission rate threshold may be 1MB/s. As another example, the network transmission rate threshold may be 2MB/s.

S305: the electronic equipment determines the current data transmission scene based on the running condition of the application and the data packet receiving and transmitting type corresponding to the application.

Under the condition that the current back shell temperature exceeds the temperature threshold and the current network transmission rate exceeds the network transmission rate threshold, the electronic equipment can determine the running condition of the application and the data packet receiving and transmitting type corresponding to the application, and determine the current data transmission scene based on the running condition of the application and the data packet receiving and transmitting type corresponding to the application.

It is understood that the running situation of the application may include information about the application running in the foreground or in the background in the electronic device. That is, the running condition of the application may include the running state of the running application. The operating states may include a foreground operating state and a background operating state, among others. This means that the electronic device can determine the application running in the foreground (i.e., the application in the foreground running state) and the application running in the background (i.e., the application in the background running state) in the electronic device based on the running condition of the application.

In some embodiments of the application, the electronic device may determine the running application based on the package name of the running application. The package name may uniquely identify the application. The electronic device may also determine, via the display process, an application running in the foreground and, via a processor (e.g., an application processor), an application running in the background.

Specifically, the electronic device may determine the application running in the foreground by displaying the rendering data in the process. That is, if the display process includes rendering data of an application, the electronic device may determine that the application is running in the foreground. The electronic device may determine the application running in the background via data processed by the application processor (e.g., data packets transmitted by the application processor). If the data processed by the application processor includes data from/to an application, the electronic device may determine that the application is running in the background.

It is understood that the data packet transceiving type corresponding to the application refers to the data packet transceiving type corresponding to the running application. The packet transceiving type may include an uplink packet and a downlink packet. The uplink data packet is a data packet transmitted on the TX link, that is, a data packet sent by the electronic device. And the downlink data packet is a data packet transmitted on the RX link, that is, a data packet received by the electronic device. If the data packet corresponding to the running application is an uplink data packet, the electronic device may determine that an upload task exists in the application. If the data packet corresponding to the running application is a downlink data packet, the electronic device may determine that a download task exists in the application.

It is understood that the data transmission scenario may roughly include two types of scenarios—an uplink transmission scenario and a downlink transmission scenario. The uplink transmission scenario may include, but is not limited to: face-to-face fast transmission scenes, backup scenes, screen throwing scenes and cloud synchronization scenes. The downstream transmission scenario may include a download scenario. In particular, a cache scenario may also be understood as a download scenario. The download scene may further specifically include a foreground download scene and a background download scene. The foreground download scene refers to a data transmission scene in which a download task exists in an application running in the foreground. The background download scene refers to a data transmission scene in which a download task exists in an application running in the background. It is understood that, similar to the download scenario, the uplink transmission scenario may also include: foreground upload scene and background upload scene. The foreground upload scene refers to a data transmission scene in which an upload task exists in an application running in the foreground. The background uploading scene refers to a data transmission scene in which uploading tasks exist in an application running in the background.

In some embodiments of the present application, data transmission scenarios can be divided into four categories: foreground uploading scene, background uploading scene, foreground downloading scene and background downloading scene.

In particular, the data transmission scenario may also include a change clone scenario. From the above, a swap clone can be understood as a data replication and migration between two electronic devices. For the electronic equipment originally stored with data, the machine-changing cloning scene on the electronic equipment belongs to an uplink transmission scene. However, for an electronic device receiving migration data, the switch clone scenario on the electronic device belongs to the downstream transmission scenario. For convenience of description, the present application refers to a machine-changing cloning scenario belonging to an uplink transmission scenario as a machine-changing cloning scenario H1, and refers to a machine-changing cloning scenario belonging to a downlink transmission scenario as a machine-changing cloning scenario H2. It should be noted that the machine-changing cloning scenario may also include a foreground machine-changing cloning scenario and a background machine-changing cloning scenario. The foreground machine-changing cloning scene refers to: when copying and transmitting application data, the application runs in the foreground. The background machine-changing cloning scene refers to: when copying and transmitting application data, the application runs in the background. This means that the exchange cloning scenario may specifically include: foreground swap cloning scenario H1, background swap cloning scenario H1, foreground swap cloning scenario H2 and background swap cloning scenario H2. It can be appreciated that the foreground upload scene may include a foreground swap clone scene H1, the foreground download scene may include a foreground swap clone scene H2, the background upload scene may include a background swap clone scene H1, and the background download scene may include a background swap clone scene H2.

It should be noted that the data transmission scenario in the present application is not limited to the above example. In addition, the meaning of the data transmission scene in the present application is different from that of the temperature control scene, and it can be understood that the temperature control scene refers to a data transmission scene with a higher network transmission rate (for example, the network transmission rate exceeds the network transmission rate threshold).

The determining, by the electronic device, a current data transmission scenario based on the running condition of the application and the data packet receiving and transmitting type corresponding to the application may specifically include: the electronic device can determine whether the current data transmission scene is an uplink transmission scene or a downlink transmission scene based on the data packet receiving and transmitting type corresponding to the application, and then determine whether the running application runs in the foreground or the background based on the running condition of the application, so as to determine the current specific data transmission scene.

For example, if a first application in the electronic device is in a foreground running state and a data packet receiving and transmitting type corresponding to the first application is an uplink data packet, the electronic device may determine that a current data transmission scene is a foreground uploading scene. If the first application in the electronic device is in a foreground running state and the data packet receiving and transmitting type corresponding to the first application is a downlink data packet, the electronic device can determine that the current data transmission scene is a foreground downloading scene. If the first application in the electronic device is in a background running state and the data packet receiving and transmitting type corresponding to the first application is an uplink data packet, the electronic device can determine that the current data transmission scene is a background uploading scene. If the first application in the electronic device is in a background running state and the data packet receiving and transmitting type corresponding to the first application is a downlink data packet, the electronic device can determine that the current data transmission scene is a background downloading scene.

In some embodiments of the present application, the electronic device may also determine the current specific data transmission scenario in combination with other scenario information. The other scene information may include: application package name, application UID, process name (such as PID) the application is running, hardware resources the application uses, network type (such as Wi-Fi/P2P) the application uses, etc. It is understood that UID refers to a user identity (User Identification). The UID may be used to identify the application. The PID refers to a process identification (Process Identification) in the operating system. Each process has a unique PID. Wi-Fi refers to a Wireless Fidelity (i.e., WIRELESS FIDELITY) network, and P2P (Peer-to-Peer) can be understood as a Peer-to-Peer computing or Peer-to-Peer network.

For example, if the data packet receiving and transmitting type corresponding to the first application is an uplink data packet and the network type used by the first application is P2P, the electronic device may determine that the current data transmission scene is a face-to-face fast transmission scene or a screen projection scene. The electronic device can also judge whether the current data transmission scene is a front-table opposite-face fast transmission scene/front-table screen-throwing scene or a rear-table opposite-face fast transmission scene/rear-table screen-throwing scene according to the running state of the first application. If the first application runs in the foreground, the electronic device can determine that the current data transmission scene is a front-table-surface opposite-face fast transmission scene/a front-table screen-throwing scene, and if the first application runs in the background, the electronic device can determine that the current data transmission scene is a rear-table-surface opposite-face fast transmission scene/a rear-table screen-throwing scene.

It can be appreciated that, similarly, for uplink transmission scenarios such as a backup scenario and a cloud synchronization scenario, the electronic device may also determine a more specific data transmission scenario in combination with an application running state. The more specific data transmission scene may include a foreground backup scene, a background backup scene, a foreground cloud synchronization scene, a background cloud synchronization scene, and the like.

For example, if the first application is in the background running state, the data packet receiving and transmitting type corresponding to the first application is an uplink data packet, and the electronic device can determine that the first application is a machine-changing cloning application through the packet name of the first application, then the electronic device can determine that the current data transmission scene is a background machine-changing cloning scene H1. Similarly, if the first application is in the background running state, the data packet receiving and transmitting type corresponding to the first application is a downlink data packet, and the electronic device can determine that the first application is a machine-changing cloning application through the packet name of the first application, then the electronic device can determine that the current data transmission scene is a background machine-changing cloning scene H2. Similarly, if the first application is in the foreground running state, the data packet receiving and transmitting type corresponding to the first application is an uplink data packet, and the electronic device can determine that the first application is a clone application for machine switching through the packet name of the first application, then the electronic device can determine that the current data transmission scene is a clone scene H1 for machine switching of the foreground. Similarly, if the first application is in the foreground running state, the data packet receiving and transmitting type corresponding to the first application is a downlink data packet, and the electronic device can determine that the first application is a clone application for machine switching through the packet name of the first application, then the electronic device can determine that the current data transmission scene is a clone scene H2 for machine switching of the foreground.

For example, if the first application is in the foreground running state, the data packet receiving and transmitting type corresponding to the first application is an uplink data packet, and the electronic device can determine that the first application is an instant messaging application through the packet name of the first application, and determine that the first application continuously calls the front-facing camera in the electronic device, the electronic device can determine that the current data transmission scene is a video chat scene.

For example, a video application in the electronic device is running in the foreground, a data packet corresponding to the application is a downlink data packet, and data contained in the downlink data packet is temporarily stored in a buffer space of the electronic device, so that the electronic device can determine that a current data transmission scene is a buffer scene.

It is understood that the first application may be any application in an electronic device, as the application is not limited in this regard.

It should be noted that, the process of determining the current data transmission scenario by the electronic device may be understood as follows: a data transmission scenario is determined for an application running in the electronic device. In the application, the electronic device can also determine the data transmission scene for a plurality of running applications. It is appreciated that the electronic device may determine a particular implementation of a data transmission scenario for a plurality of running applications by combining the above determination of a particular implementation of a data transmission scenario for a running application.

For example, a first application in the electronic device is in a foreground running state, a data packet receiving and transmitting type corresponding to the first application is an uplink data packet, a network type used by the first application is P2P, and meanwhile, a second application in the electronic device is in a background running state, a data packet receiving and transmitting type corresponding to the second application is a downlink data packet, and then the electronic device may determine that the current data transmission scenario includes: the front table corresponding to the first application faces the fast transmission scene/the front screen projection scene, and the background downloading scene corresponding to the second application.

It is to be appreciated that the specific implementation of the electronic device to determine a data transmission scenario for a plurality of running applications is not limited to the examples described above.

S306: the electronic device determines a target network transmission rate based on the current backshell temperature and the current data transmission scenario.

In some embodiments of the present application, the electronic device may have stored therein a correspondence of standard back-case temperature, data transmission scenario, and standard network transmission rate. The electronic device may determine a standard backshell temperature and a standard network transmission rate corresponding to the current data transmission scenario based on the correspondence.

It is understood that the correspondence may be set according to actual needs, which is not limited by the present application. In some embodiments of the application, the standard backshell temperature is not greater than the backshell temperature threshold.

For example, as shown in the following table 4, when the standard back shell temperature corresponding to the foreground swap cloning scenario H1 is 43 ℃, the standard network transmission rate corresponding to the standard back shell temperature is 10MB/s. When the standard backshell temperature corresponding to the background machine-changing cloning scene H1 is 43 ℃, the standard network transmission rate corresponding to the background machine-changing cloning scene H1 is 5MB/s. And when the standard backshell temperature corresponding to the background uploading scene is 43 ℃, the standard network transmission rate corresponding to the background uploading scene is 1MB/s.

TABLE 4 Table 4

It is to be understood that table 4 above is merely an example provided by the present application and should not be construed as limiting the present application.

It is understood that the same data transmission scenario may correspond to several standard back-case temperatures and several standard network transmission rates. In this case, the electronic device may select any one of the standard back-case temperature and the standard network transmission rate corresponding to the current data transmission scenario.

In one possible implementation manner, the electronic device may determine a standard backshell temperature closest to the current backshell temperature, and find a standard network transmission rate corresponding to the standard backshell temperature closest to the current backshell temperature and the current data transmission scene in the corresponding relationship, where the standard network transmission rate is the target network transmission rate.

In one possible implementation, the electronic device may determine a minimum standard back shell temperature corresponding to the current data transmission scenario and a standard network transmission rate corresponding to the minimum standard back shell temperature, where the standard network transmission rate is the target network transmission rate.

In some embodiments of the present application, the electronic device may store a correspondence between a standard back-case temperature interval, a data transmission scenario, and a standard network transmission rate. It is understood that the correspondence may be set according to actual needs, which is not limited by the present application.

For example, as shown in table 5 below, when the standard backshell temperature interval corresponding to the foreground download scenario is (40 ℃,43 ℃), the standard network transmission rate corresponding to the foreground download scenario is 7MB/s. And when the standard backshell temperature interval corresponding to the background downloading scene is (40 ℃ and 43 ℃), the corresponding standard network transmission rate is 5MB/s. And when the standard backshell temperature interval corresponding to the background application download scene is (35 ℃ and 40 ℃), the corresponding standard network transmission rate is 1MB/s.

TABLE 5

Standard backshell temperature interval (DEG C)	Data transmission scenario	Standard network transmission rate (MB/s)
			(40,43)	Foreground download scene	7
(40,43)	Background download scene	5
			(35,40)	Background download scene	1
…	…	…

It is to be understood that table 5 above is merely an example provided by the present application and should not be construed as limiting the present application.

It is understood that the same data transmission scenario may correspond to several standard backshell temperature intervals and several standard network transmission rates. In this case, the electronic device may select any one of the standard back shell temperature interval and the standard network transmission rate corresponding to the current data transmission scenario.

In one possible implementation manner, the electronic device may determine a standard backshell temperature interval in which the maximum value of the interval is closest to the current backshell temperature, and find a standard network transmission rate corresponding to the standard backshell temperature interval and the current data transmission scene in the corresponding relationship, where the standard network transmission rate is the target network transmission rate.

In one possible implementation manner, the electronic device may determine a standard backshell temperature interval with a minimum interval value corresponding to the current data transmission scene and a standard network transmission rate corresponding to the standard backshell temperature interval, where the standard network transmission rate is the target network transmission rate.

In some embodiments of the application, the electronic device may obtain the current chip temperature and the ambient temperature. The electronic device may determine a target backshell temperature based on the current backshell temperature and the current data transmission scenario, and determine a target transmission power based on the target backshell temperature and the current ambient temperature. The electronic device may also determine a target transmission rate based on the target transmission power and the current chip temperature.

It is understood that chip temperature refers to the temperature of the processor chip. The transmission power refers to the power of a hardware module performing data transmission when transmitting data. For example, as shown in fig. 2, the transmission power may be the overall power of the application processor and the communication module (including the modem, the radio frequency integrated circuit, and the antenna 1) during data transmission.

In one possible implementation, the electronic device may store a correspondence of standard back-case temperatures and data transmission scenarios (as shown in table 4). In this case, the electronic device may determine a standard back case temperature corresponding to the current data transmission scenario, which is the target back case temperature.

For ease of description, the present application will refer to the chip temperature as T _a, the ambient temperature as T _b, and the backshell temperature as T _c.

In one possible implementation, the electronic device may determine a relationship of transmission power, chip temperature, and network transmission rate based on the Landolt principle. Specifically, the present application provides a relational expression of limiting transmission power and network transmission rate: p=β×k×t _a ×v×ln 2+P (v). Where P represents the limit transmission power, i.e. the maximum transmission power under the condition that other parameters are determined, β is a compensation factor, k is a boltzmann constant, v represents the network transmission rate, and P (v) represents the power consumption (i.e. power) generated by a communication module (such as PA, LNA, etc.). P is expressed in watts per second (w/s), and v is expressed in bits per second (b/s).

It can be appreciated that the Landolt principle includes: the minimum energy expended to erase 1 bit (bit) information is kT _a ln 2 joules (J). The relationship between the network transmission rate (i.e. v) and the limiting power (i.e. pl) can be obtained based on the Landolt principle: pl=k×t _a ×v×ln 2. Wherein, the unit of pl is w/s.

The actual physical structure is far from satisfactory because the Landolt principle describes the physical limits that can be reached in an ideal state. This means that in practice the limit transmission power at a certain chip temperature and network transmission rate is much greater than pl, which is determined on the basis of the lander principle. Therefore, the present application compensates for pl in an ideal state by the compensation factor β. Beta can be set according to actual needs, and the application is not limited to this. For example, β may range from (10 ⁵,10⁶). The skilled person can determine the specific value of beta by repeating the experiment.

It will be appreciated that the skilled person can determine P (v) by repeating the experiment. In particular, the electronic device may determine P (v) based on v and several sets of specific values of P. P (v) may be a piecewise function.

In one possible implementation, the electronic device may determine a backshell temperature to limit transmission power correspondence. Specifically, the application provides a relational expression of the rear shell temperature and the limit transmission power: p= (T _c-T_b)/R_t. Wherein, the heat dissipation coefficient is a parameter which is uniformly transformed by coefficient such as thermal resistance. R _t is determined by hardware of the electronic device and can be regarded as a fixed parameter.

For convenience of description, the present application refers to the current back shell temperature as T _c 1, the target back shell temperature as T _c 2, the current chip temperature as T _a 1, the current ambient temperature as T _b 1, the current network transmission rate as V1, the target network transmission rate as V2, the current transmission power as p1, and the target transmission power as p2.

Based on the foregoing, the electronic device determines a target backshell temperature based on the current backshell temperature, determines a target transmission power based on the target backshell temperature and the current ambient temperature, and then determines a target transmission rate based on the target transmission power and the current chip temperature, which may specifically include: the electronic device may determine that the standard backshell temperature corresponding to the current data transmission scenario and the current backshell temperature (i.e. T _c 1) is T _c 2, and substitutes T _c 2 and T _b into the expression p= (T _c-T_b)/R_t), so as to obtain p2., i.e. p 2= (T _c2-T_b1)/R_t. The electronic device may also substitute T _a 1 and p2 into the expression p=β×k×t _a ×v×ln 2+P (v), so as to obtain p2=β×k×t _a 1×v2×ln2+p (v 2), thereby calculating v2.

It is understood that the specific manner in which the electronic device determines the target network transmission rate based on the current back-case temperature and the current data transmission scenario is not limited to the above examples.

S307: the electronic device adjusts the network transmission rate to a target network transmission rate.

It is understood that the electronic device may control the rate at which the application processor receives/transmits data packets to be the target network transmission rate. In particular, the electronic device may limit the number of packets that the application processor sends to the modem, or the number of packets that the application processor receives from the modem, over a period of time based on the target network transmission rate.

In some embodiments of the application, the electronic device may adjust the network transmission rate to the target network transmission rate through TC flow control. It is understood that the relevant description of TC flow control may refer to the relevant technical documents, which are not explained here.

In still other embodiments of the present application, the electronic device may adjust the network transmission rate to the target network transmission rate based on Qlink queue rules. It is understood that the relevant description of Qlink queue rules may refer to the relevant technical documents, which are not described herein.

Of course, the electronic device may adjust the network transmission rate to the target network transmission rate in other manners, which the present application is not limited to.

It should be noted that, in some embodiments of the present application, the electronic device may repeatedly perform steps S301-S307. For example, the electronic device may detect the current back shell temperature and the current network transmission rate once every first time period, and then may continue to perform steps S302, S304-S307.

In some embodiments of the present application, after the electronic apparatus performs step S307, the execution of step S301 and step S303 may be temporarily stopped. For example, the electronic device may temporarily stop the step of detecting the current back-case temperature and the current network transmission rate once every first time period. In this case, the electronic device may continuously monitor the data transmission scene, and once the current data transmission scene changes, the electronic device may resume performing steps S301-S307. It is understood that the continuous monitoring of the data transmission scenario by the electronic device can be understood as: the electronic device may detect whether the data transmission scene changes every second time period. The second duration may be set according to actual needs, which is not limited by the present application. For example, the second duration may be 3 minutes. It is understood that the electronic device restarting the execution of step S301-step S307 may include: the electronic device resumes executing the step of detecting the current back-case temperature and the current network transmission rate once every first duration.

The following describes a software structure of an electronic device provided by the present application.

Referring to fig. 4, fig. 4 is a schematic software structure of an electronic device according to an embodiment of the application.

As shown in fig. 4, the software framework of the electronic device according to the present application may include an application layer, an application framework layer (FWK), a system library, an Zhuoyun lines, a hardware abstraction layer, and a kernel layer (kernel).

The application layer may include a series of application packages, among other things. For example: camera, gallery, calendar, etc. (also referred to as applications). The application program layer can also comprise a network statistics module, a scene identification module, a temperature acquisition module and a temperature control module. The network statistics module may be configured to obtain network information such as a network transmission rate, an uplink and downlink data transmission rate, and a data packet size. The scene recognition module may be configured to obtain scene information (e.g., the running condition of an application) and determine a current data transmission scene based on the scene information. The temperature acquisition module may be used to acquire temperature information such as back-case temperature, ambient temperature, and chip temperature. The temperature control module may be configured to determine a target network transmission rate based on a current back-case temperature and a current data transmission scenario.

The application framework layer provides an application programming interface (Application Programming Interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions.

As shown in fig. 4, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like. The window manager is used for managing window programs. Content providers are used to store and retrieve data (e.g., video, images, audio, etc.) and make such data accessible to applications. The view system includes visual controls. The view system may be used to build applications. The display interface may be composed of one or more views. The telephony manager is for providing communication functions of the electronic device. Such as the management of call status (including on, hung-up, etc.). The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. The notification manager allows the application to display notification information in a status bar. The notification manager may also be a notification presented in the form of a chart or scroll bar text in the system top status bar, or a notification presented on screen in the form of a dialog interface.

The Runtime (run time) includes core libraries and virtual machines. Run time is responsible for scheduling and management of the system. The core library consists of two parts: one part is the function that the programming language (e.g., java language) needs to call, and the other part is the core library of the system. The application layer and the application framework layer run in a virtual machine. The virtual machine executes the programming files (e.g., java files) of the application layer and the application framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface Manager (Surface Manager), media library (Media Libraries), three-dimensional graphics processing library (e.g., openGL ES), two-dimensional graphics engine (e.g., SGL), etc. The surface manager is used to manage the display subsystem and provides a fusion of two-Dimensional (2D) and three-Dimensional (3D) layers for multiple applications. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing 3D graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

A Hardware Abstraction Layer (HAL) is an interface layer located between the operating system kernel and upper layer software, which aims at abstracting the hardware. The hardware abstraction layer is a device kernel driven abstraction interface for enabling application programming interfaces that provide higher level Java API frameworks with access to the underlying devices. The HAL comprises a plurality of library modules, such as a camera HAL, an audio HAL, etc. Wherein each library module implements an interface for a particular type of hardware component. When the system framework layer API requires access to the hardware of the portable device, the Android operating system will load the library module for that hardware component.

The kernel layer is the basis of the Android operating system, and the final functions of the Android operating system are completed through the kernel layer. The kernel layer may contain display drivers, camera drivers, audio drivers, sensor drivers, etc.

The kernel layer may also include a network driver module. The network driver module may be used to control the network transmission rate.
