Description

Resource scheduling device, mobile terminal and resource scheduling method

Technical Field

The present invention relates to the technical field of mobile terminal devices, and in particular, to a resource scheduling apparatus, a mobile terminal, and a resource scheduling method.

Background

At present, as the functions of the mobile terminal become more and more rich, more and more resources are consumed by the related application programs during running, and meanwhile, the response speed of people to the application programs is more and more sensitive. In the resource scheduling of the conventional mobile terminal system, in consideration of power consumption, heat dissipation and other factors, a method of limiting the frequency by using a switch core or a Central Processing Unit (CPU) is mostly adopted, but this may reduce the response speed of the application program.

When the mobile terminal runs a certain application program and consumes memory resources, the CPU reaches a closing threshold value and is automatically closed. For this situation, the conventional solution includes: (1) the CPU core is always kept fully open, temperature influence is not considered, and the CPU core is not closed even if the temperature exceeds a closing threshold value. This results in a higher response speed, but at the cost of higher power consumption and heat generation, and also reduces the lifetime of the terminal device. (2) The temperature influence of each CPU is considered, and when the temperature influence exceeds a threshold value, the CPU is closed, so that low power consumption and heat generation are kept to the maximum extent, but the performance of the application is reduced, and the utilization rate of resources is low.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication means such as wired and wireless communication means and satellite-based communication means that transmit data via frames or packets.

A communication apparatus in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication devices may use different air interfaces and/or physical layers. For example, the air interface used by the communication device includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and universal mobile telecommunications device (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and so forth. The following description relates to a CDMA communication device, as a non-limiting example, but such teachings are equally applicable to other types of devices.

Referring to fig. 2, the CDMA wireless communication apparatus may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that an apparatus as shown in fig. 2 may include a plurality of BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a base transceiver sub-assembly (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the apparatus. In fig. 2, several global positioning device (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication apparatus, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above-mentioned hardware structure of the mobile terminal and the structure of the communication device, the present invention provides various embodiments of the method.

Fig. 3 shows a first embodiment of a resource scheduling apparatus according to the present invention. The resource scheduling apparatus of this embodiment includes:

a curvature obtaining module 10, configured to obtain a curvature of a core temperature of a central processing unit of the mobile terminal changing within a specified time period;

in this embodiment, the type of the mobile terminal may be set according to actual needs, for example, a mobile terminal handset, an ipad, and the like. The mobile terminal comprises a resource scheduling device, and in the using process of the mobile terminal, the core temperature of a central processing unit of the mobile terminal may show different changes in different using time periods. For example, in the first period of time, when a user reads a document by using the mobile terminal, the power consumption of the mobile terminal is low, and the core temperature of the central processing unit is low. And in the second time period, the user uses the mobile terminal to play the game, the power consumption of the mobile terminal is higher, and the temperature of the inner core of the central processing unit is higher.

In order to adjust the reference frequency of the central processing unit, in an embodiment, the mobile terminal may detect the core temperature of the central processing unit in a certain period of time at regular intervals, and obtain the curvature of the core temperature change according to the core temperature in the period of time. In another embodiment, the core temperature of the central processing unit in a specified time period is detected if necessary, for example, when the mobile terminal runs in browsing pictures, the total consumption of resources of the mobile terminal is small, and then the curvature of the core temperature change does not need to be acquired; when the mobile terminal runs in a game scene, the total consumption of the mobile terminal resources is large, and at this time, the curvature of the change of the core temperature needs to be acquired. The curvature acquiring module 10 then acquires the curvature of the core temperature change in the specified time period according to the core temperature in the specified time period.

The curvature of the core temperature changing in different time periods is shown in fig. 4, the horizontal axis in fig. 4 is time, the vertical axis is the core temperature, and k1, k2, k3 and k4 respectively represent the curvature changing in different time periods, wherein, the curvature of the core temperature changing is larger in k1> k2> k3> k4, which indicates that the faster the core temperature rises, the shorter the time point of reaching the core closing temperature. Conversely, a smaller curvature of the core temperature change indicates a slower core temperature rise and a longer time to core shutdown.

A reference frequency adjusting module 20, configured to adjust a reference frequency of the central processing unit according to the curvature;

in this embodiment, the reference frequency of the central processing unit may be a default reference frequency, or may be a preset reference frequency of the central processing unit. Optionally, a third preset percentage of the maximum operating frequency of the central processing unit is set as the reference frequency, and the third preset percentage may be set to 80%, or may be flexibly set according to specific situations. For example, when the mobile terminal supports 8-core central processing units, and the maximum operating frequency of a single central processing unit is 2000Hz, the reference frequency of the central processing unit is set to 2000Hz × 80% — 1600 Hz.

After obtaining the curvature of the core temperature changing in the specified time period, the reference frequency adjusting module 20 determines the size of the curvature, and adjusts the reference frequency of the central processing unit according to the determination result. For example, if the curvature is within the acceptable interval [ a, b ], it is considered that the reference frequency does not need to be adjusted within a reasonable range; if the curvature is larger than b, setting the reference frequency of the central processing unit to be x% of the current operation frequency reduced on the basis of the current operation frequency; and if the curvature is smaller than a, setting the reference frequency of the central processing unit to be y% of the current operation frequency increased on the basis of the current operation frequency. It should be noted that, when the central processing unit operates at the reference frequency, all cores of the mobile terminal are working, thereby avoiding the waste of core resources. a. The specific values of b, x and y can be set according to actual conditions.

A frequency and temperature obtaining module 30, configured to obtain a current operating frequency of the central processing unit and a current temperature of the kernel every first preset time;

after the reference frequency of the central processing unit is adjusted, in order to meet the requirement of the mobile terminal for application resource scheduling and under the condition that all cores of the mobile terminal are working, the temperature of the cores is not too high, and at the moment, the operation frequency of the central processing unit needs to be adjusted according to the current operation frequency of the central processing unit and the current temperature of the cores. First, the frequency and temperature obtaining module 30 obtains the current operating frequency of the cpu and the current temperature of the core every first preset time, and the first preset time can be flexibly set according to specific situations.

And the operating frequency adjusting module 40 is configured to, when the current operating frequency is greater than the reference frequency, correspondingly adjust the operating frequency of the central processing unit according to a size relationship between the current temperature and a preset core shutdown temperature, so as to perform application resource scheduling according to the operating frequency adjusted by the central processing unit.

In this embodiment, the mobile terminal is preset with a core closing temperature, and when the temperature of the core reaches the core closing temperature, the corresponding central processing unit is closed, so as to prevent the core temperature from continuously rising. After obtaining the current operating frequency of the central processing unit and the current temperature of the core, the operating frequency adjusting module 40 compares the current operating frequency of the central processing unit with the reference frequency, compares the current temperature of the core with the preset core closing temperature, and adjusts the operating frequency of the central processing unit according to the comparison result of the current operating frequency of the central processing unit and the preset core closing temperature to achieve dynamic balance. For example, if the current operating frequency is greater than the reference frequency and the current temperature of the core is higher than the core closing temperature, the operating frequency of the central processing unit is reduced until the temperature is reduced to a certain range; when the current temperature of the core is lower than a certain value, namely the difference between the current temperature and the core closing temperature is larger, the running frequency of the central processing unit is improved, and the system can process more tasks. Therefore, the cores of all central processing units of the mobile terminal can be ensured to work, the temperature of the cores fluctuates in a proper range, and the mobile terminal can carry out application resource scheduling according to the running frequency of the central processing units. The influence of the operating frequency of the central processing unit and the temperature of the kernel is comprehensively considered, the software and hardware resources of the system can obtain higher utilization rate, meanwhile, the aspects of power consumption, heating, mobile terminal performance and the like are considered, the program processing capacity and the response speed of the mobile terminal are improved, and the user experience is improved.

For example, it is assumed that the terminal supports 8-core cpus, the core off temperature of each cpu is 60 ℃, the maximum operating frequency of a single cpu is 2000Hz, the reference frequency of the cpu operation is 1600Hz, and the core of the cpu 8 is fully opened. When the mobile terminal runs in a game scene, the mobile terminal adjusts the running reference frequency of the central processing unit to 1500Hz according to the curvature of the core temperature changing in a specified time period, and then obtains the current running frequency of the central processing unit to be 1700Hz and the current temperature of the core to be 55 ℃. Then comparing the current running frequency of the central processing unit with the reference frequency, and simultaneously comparing the current temperature of the inner core with the preset inner core closing temperature. At this time, the current operating frequency 1700Hz of the central processing unit is greater than the reference frequency 1500Hz, and the current temperature 55 ℃ of the core is greater than 90% of the core closing temperature, so that the operating frequency of the central processing unit is reduced to 1500 Hz. Thereafter, the core temperature is gradually decreased, when the core temperature is decreased to 80% of the core off temperature, i.e. the core temperature is decreased to 48 ℃, the operating frequency of the cpu is slowly increased from 1500Hz, for example, the operating frequency is increased by 50Hz every 1 minute, when the current operating frequency of the cpu is greater than the reference frequency and the current temperature of the core is greater than the core off temperature, the operating frequency of the cpu is decreased to the reference frequency, and the process is repeated. The central processing unit of the mobile terminal can float in frequency by taking the frequency of 1500Hz as a reference frequency, all the cores can be ensured to work, power consumption, performance and the like can be ensured on the basis of the existing software and hardware resources of the mobile terminal, the program processing capacity and the response speed of the terminal are improved, and the satisfaction degree of a user on the use of the mobile terminal is improved.

Further, based on the first embodiment of the resource scheduling apparatus, a second embodiment of the resource scheduling apparatus of the present invention is provided, where the difference between this embodiment and the first embodiment of the resource scheduling apparatus of the present invention is that the reference frequency adjusting module 20 in this embodiment is further configured to, when the curvature is greater than a first preset curvature value, reduce the reference frequency of the central processing unit by a first preset value; when the curvature is smaller than a second preset curvature value, increasing the reference frequency of the central processing unit by a second preset value; the second preset curvature value is smaller than the first preset curvature value.

In this embodiment, after the reference frequency of the central processing unit is set, in the process of adjusting the reference frequency of the central processing unit according to the curvature of the core temperature change, the reference frequency adjusting module 20 may preset a mapping relationship between the curvature interval and the reference frequency adjusting amplitude, after the curvature of the core temperature change is obtained, match the curvature with the preset curvature interval, determine the curvature interval in which the curvature is located, and adjust the reference frequency according to the adjusting amplitude corresponding to the curvature interval according to the mapping relationship between the curvature interval and the reference frequency adjusting amplitude. For example, the curvature is divided into three curvature intervals, the first curvature interval is that the curvature k is smaller than the curvature a, and the corresponding reference frequency is adjusted to be decreased by a first preset frequency value; the second curvature interval is that the curvature k is larger than the curvature a and smaller than the curvature b, and the corresponding reference frequency adjusting amplitude is zero; and the third curvature interval is that the curvature k is larger than the curvature b, and the corresponding reference frequency adjusting amplitude is a second preset frequency value.

Specifically, when the curvature of the core temperature change is greater than a first preset curvature value, which indicates that the core temperature rises faster at this time, the time to reach the core closing temperature is shorter, and the reference frequency adjusting module 20 needs to reduce the reference frequency of the central processing unit operation by a first preset value to increase the time to reach the core closing temperature. The first predetermined curvature value and the first predetermined value can be flexibly set according to specific situations. For example, the first preset value may be set to ten percent of the current reference frequency, or fixed 100Hz, etc. When the curvature of the change of the core temperature is smaller than the second preset curvature value, which indicates that the core temperature rises slowly at this time and the time for reaching the core closing temperature is longer, the reference frequency adjusting module 20 can increase the reference frequency of the central processing unit to the second preset value, so that the system processes more tasks and improves the resource utilization rate. The first preset curvature value is larger than the second preset curvature value, the second preset curvature value and the second preset value can be flexibly set according to specific conditions, and the second preset value can be set to be consistent with or inconsistent with the first preset value. When the curvature of the temperature change of the inner core is smaller than or equal to a first preset curvature value and larger than or equal to a second preset curvature value, the reference frequency of the running of the central processing unit does not need to be adjusted.

In the embodiment, the reference frequency of the operation of the central processing unit is correspondingly adjusted according to the curvature of the temperature change of the cores, so that all the cores work, and the waste of core resources is avoided. And the mobile terminal is ensured to operate under the application of different power consumption (for example, playing games, reading and the like) to set corresponding reference frequency, so that the temperature of the inner core fluctuates in a proper range, and the resource utilization rate and the service life of the mobile terminal are improved.

Further, based on the first embodiment of the resource scheduling apparatus, a third embodiment of the resource scheduling apparatus of the present invention is provided, where a difference between this embodiment and the first embodiment of the resource scheduling apparatus of the present invention is that the operating frequency adjusting module 40 in this embodiment includes:

In this embodiment, in the process of adjusting the operating frequency of the central processing unit, the mobile terminal compares the current operating frequency of the central processing unit with the reference frequency, and simultaneously compares the current temperature of the core with a preset core closing temperature, if the current operating frequency is greater than the reference frequency and the current temperature reaches a first preset percentage of the core closing temperature, it indicates that the current temperature of the core is approaching to the core closing temperature, and at this time, the first adjusting unit reduces the operating frequency of the central processing unit to the reference frequency, so that the core temperature gradually decreases. The first preset percentage of the core shutdown temperature may be set to 90% of the core shutdown temperature, and of course, the first preset percentage may also be set according to actual conditions. If the current operating frequency is less than or equal to the reference frequency or the current temperature does not reach the first preset percentage of the core closing temperature, the operating frequency of the central processing unit does not need to be adjusted, namely, the central processing unit maintains the current operating frequency.

After the operation frequency of the central processing unit is adjusted, the new temperature of the core is obtained, when the new temperature is reduced to a second preset percentage of the core closing temperature, the temperature difference between the current temperature and the core closing temperature is large, the second adjusting unit adjusts the operation frequency of the central processing unit to a preset frequency value every second preset time, so that the operation frequency of the central processing unit is slowly increased, and the system can process more tasks. The second predetermined percentage of the core shutdown temperature may be set to 80% of the core shutdown temperature, and of course, the first predetermined percentage may also be set according to actual conditions. The second predetermined time and the predetermined frequency value can also be set according to the actual situation, for example, 50Hz is adjusted up every 1 minute. When the current operating frequency of the central processing unit is greater than the reference frequency and the current temperature of the core is greater than the core closing temperature, the operating frequency of the central processing unit is reduced to the reference frequency, and the operation is repeated in a circulating mode.

It can be understood that, if the current operating frequency is greater than the reference frequency, the current temperature is less than the core closing temperature, and the temperature difference between the current temperature and the core closing temperature is less than the preset temperature difference, the operating frequency of the central processing unit is reduced by the preset frequency, the preset temperature difference and the preset frequency can be set according to the actual situation, the preset temperature difference can be divided into a plurality of temperature difference intervals, and each temperature difference interval corresponds to different preset frequencies.

According to the embodiment, the operating frequency of the central processing unit is correspondingly adjusted according to the size relationship between the current operating frequency and the reference frequency and the size relationship between the current temperature and the core closing temperature, so that not only can the cores of all the central processing units of the mobile terminal be ensured to work, the core temperature fluctuates in a proper range, but also the operating frequency of the central processing unit and the influence of the temperature of the cores are comprehensively considered, the aspects of power consumption, heating, performance and the like are considered, and the resource utilization rate, the response speed and the service life of the mobile terminal are improved.

Further, as shown in fig. 5, a fourth embodiment of the resource scheduling apparatus of the present invention is proposed based on the first embodiment of the resource scheduling apparatus, and the difference between this embodiment and the first embodiment of the resource scheduling apparatus of the present invention is that a processing module 50 is added, and the resource scheduling apparatus in this embodiment includes:

And the processing module 50 is configured to obtain a total consumption amount of the mobile terminal resource every third preset time, and when the total consumption amount is greater than a preset consumption amount, obtain a temperature of the kernel in a specified time period.

Only the differences between this embodiment and the first embodiment of the resource scheduling apparatus of the present invention are described below, and other modules may refer to the detailed description of the first embodiment, which is not repeated herein.

In this embodiment, the mobile terminal may obtain the temperature of the core temperature in the specified time period only when the total consumption amount of the resource is high, and adjust the reference frequency of the central processing unit according to the curvature of the temperature change in the time period. Specifically, first, the mobile terminal calls the processing module 50 to obtain the total consumption amount of the resource every third preset time, and compares the total consumption amount of the resource with the preset consumption amount, where the third preset time and the preset consumption amount can be flexibly set according to specific situations. When the total consumption is greater than the preset consumption, which indicates that the current resource consumption of the mobile terminal is greater at this time, the system needs to process more tasks, the processing module acquires the temperature of the kernel in a specified time period, so that the mobile terminal can adjust the reference frequency of the central processing unit according to the curvature of the temperature change in the specified time period, and the specified time period can be set to be a time period when the total consumption of the resources is greater than the preset consumption. When the total consumption is less than or equal to the preset consumption, the total consumption of the mobile terminal resources is less, and the reference frequency of the operation of the central processing unit does not need to be adjusted by acquiring the curvature of the temperature change of the inner core.

In this embodiment, when the total consumption amount of the resources is greater than the preset consumption amount, the mobile terminal needs to acquire the temperature of the core within the specified time period, so as to acquire the curvature of the temperature change within the specified time period to adjust the reference frequency of the central processing unit, thereby improving the rationality of acquiring the curvature of the core temperature change within the specified time period and the accuracy of adjusting the reference frequency.

Correspondingly, the present invention provides a mobile terminal, which includes the resource scheduling device with the above structure, and the working principle and implementation manner of the resource scheduling device can refer to fig. 3 to fig. 5 and the corresponding embodiments thereof, including all technical features therein, which are not described herein again. The mobile terminal can be a mobile phone, an iPad and the like. In the embodiment of the mobile terminal, after the mobile terminal adjusts the running reference frequency of the central processing unit through the curvature of the change of the core temperature of the central processing unit in the specified time period, the current running frequency of the central processing unit obtained at intervals of a first preset time is compared with the reference frequency, the current temperature of the core is obtained and compared with the preset core closing temperature, and the running frequency of the central processing unit is adjusted according to the comparison result, so that the mobile terminal can carry out resource scheduling according to the adjusted running frequency of the central processing unit. The fluctuation of the core temperature in a proper range is realized, all cores of the mobile terminal are ensured to work, the resource utilization rate of the mobile terminal is improved, and the service life of the mobile terminal is prolonged.

Correspondingly, as shown in fig. 6, a first embodiment of a resource scheduling method according to the present invention is provided. The resource scheduling method of this embodiment corresponds to the first embodiment of the resource scheduling apparatus described above, and the resource scheduling method of this embodiment includes:

s10, acquiring the curvature of the change of the core temperature of the central processing unit of the mobile terminal in a specified time period;

In order to adjust the reference frequency of the central processing unit, in an embodiment, the mobile terminal may detect the core temperature of the central processing unit in a certain period of time at regular intervals, and obtain the curvature of the core temperature change according to the core temperature in the period of time. In another embodiment, the core temperature of the central processing unit in a specified time period is detected if necessary, for example, when the mobile terminal runs in browsing pictures, the total consumption of resources of the mobile terminal is small, and then the curvature of the core temperature change does not need to be acquired; when the mobile terminal runs in a game scene, the total consumption of the mobile terminal resources is large, and at this time, the curvature of the change of the core temperature needs to be acquired. Then, according to the core temperature in the specified time period, the curvature of the core temperature change in the specified time period is obtained.

Step S20, adjusting the operating reference frequency of the central processing unit according to the curvature;

After the curvature of the core temperature changing in the appointed time period is obtained, the size of the curvature is judged, and the reference frequency of the central processing unit is adjusted according to the judgment result. For example, if the curvature is within the acceptable interval [ a, b ], it is considered that the reference frequency does not need to be adjusted within a reasonable range; if the curvature is larger than b, setting the reference frequency of the central processing unit to be x% of the current operation frequency reduced on the basis of the current operation frequency; and if the curvature is smaller than a, setting the reference frequency of the central processing unit to be y% of the current operation frequency increased on the basis of the current operation frequency. It should be noted that, when the central processing unit operates at the reference frequency, all cores of the mobile terminal are working, thereby avoiding the waste of core resources. a. The specific values of b, x and y can be set according to actual conditions.

Step S30, acquiring the current operating frequency of the central processing unit and the current temperature of the kernel every other first preset time;

after the reference frequency of the central processing unit is adjusted, in order to meet the requirement of the mobile terminal for application resource scheduling and under the condition that all cores of the mobile terminal are working, the temperature of the cores is not too high, and at the moment, the operation frequency of the central processing unit needs to be adjusted according to the current operation frequency of the central processing unit and the current temperature of the cores. Firstly, the mobile terminal acquires the current operating frequency of the central processing unit and the current temperature of the kernel every first preset time, and the first preset time can be flexibly set according to specific conditions.

And step S40, when the current operating frequency is greater than the reference frequency, correspondingly adjusting the operating frequency of the central processing unit according to the size relation between the current temperature and the preset core closing temperature, so as to perform application resource scheduling according to the operating frequency adjusted by the central processing unit.

In this embodiment, the mobile terminal is preset with a core closing temperature, and when the temperature of the core reaches the core closing temperature, the corresponding central processing unit is closed, so as to prevent the core temperature from continuously rising. After the current operating frequency of the central processing unit and the current temperature of the kernel are obtained, the mobile terminal compares the magnitude relation between the current operating frequency of the central processing unit and the reference frequency, compares the magnitude relation between the current temperature of the kernel and the preset kernel closing temperature, and adjusts the operating frequency of the central processing unit according to the comparison result of the current operating frequency of the kernel and the preset kernel closing temperature so as to achieve dynamic balance. For example, if the current operating frequency is greater than the reference frequency and the current temperature of the core is higher than the core closing temperature, the operating frequency of the central processing unit is reduced until the temperature is reduced to a certain range; when the current temperature of the core is lower than a certain value, namely the difference between the current temperature and the core closing temperature is larger, the running frequency of the central processing unit is improved, and the system can process more tasks. Therefore, the cores of all central processing units of the mobile terminal can be ensured to work, the temperature of the cores fluctuates in a proper range, and the mobile terminal can carry out application resource scheduling according to the running frequency of the central processing units. The influence of the operating frequency of the central processing unit and the temperature of the kernel is comprehensively considered, the software and hardware resources of the system can obtain higher utilization rate, meanwhile, the aspects of power consumption, heating, mobile terminal performance and the like are considered, the program processing capacity and the response speed of the mobile terminal are improved, and the user experience is improved.

Further, based on the first embodiment of the resource scheduling method, a second embodiment of the resource scheduling method of the present invention is provided, where the resource scheduling method of this embodiment corresponds to the second embodiment of the resource scheduling apparatus, and a difference between this embodiment and the first embodiment of the resource scheduling method of the present invention is that step S20 in this embodiment includes: when the curvature is larger than a first preset curvature value, reducing the reference frequency of the central processing unit by a first preset value; when the curvature is smaller than a second preset curvature value, increasing the reference frequency of the central processing unit by a second preset value; the second preset curvature value is smaller than the first preset curvature value.

In this embodiment, after the reference frequency of the central processing unit is set, in the process of adjusting the reference frequency of the central processing unit according to the curvature of the core temperature change, in order to accurately adjust the reference frequency, the mobile terminal may preset a mapping relationship between the curvature interval and the reference frequency adjustment amplitude, after the curvature of the core temperature change is obtained, match the curvature with the preset curvature interval, determine the curvature interval where the curvature is located, and adjust the reference frequency according to the adjustment amplitude corresponding to the curvature interval according to the mapping relationship between the curvature interval and the reference frequency adjustment amplitude. For example, the curvature is divided into three curvature intervals, the first curvature interval is that the curvature k is smaller than the curvature a, and the corresponding reference frequency is adjusted to be decreased by a first preset frequency value; the second curvature interval is that the curvature k is larger than the curvature a and smaller than the curvature b, and the corresponding reference frequency adjusting amplitude is zero; and the third curvature interval is that the curvature k is larger than the curvature b, and the corresponding reference frequency adjusting amplitude is a second preset frequency value.

Specifically, when the curvature of the change of the core temperature is greater than a first preset curvature value, it indicates that the core temperature rises faster at this time, and the time to reach the core turn-off temperature is shorter, and it is necessary to reduce the reference frequency of the cpu operation by the first preset value to increase the time to reach the core turn-off temperature. The first predetermined curvature value and the first predetermined value can be flexibly set according to specific situations. For example, the first preset value may be set to ten percent of the current reference frequency, or fixed 100Hz, etc. When the curvature of the change of the temperature of the inner core is smaller than the second preset curvature value, the temperature of the inner core rises slowly at the moment, the time for reaching the closing temperature of the inner core is longer, the reference frequency of the operation of the central processing unit can be increased by the second preset value, the system can process more tasks, and the resource utilization rate is improved. The first preset curvature value is larger than the second preset curvature value, the second preset curvature value and the second preset value can be flexibly set according to specific conditions, and the second preset value can be set to be consistent with or inconsistent with the first preset value. When the curvature of the temperature change of the inner core is smaller than or equal to a first preset curvature value and larger than or equal to a second preset curvature value, the reference frequency of the running of the central processing unit does not need to be adjusted.

Further, based on the first embodiment of the resource scheduling method, a third embodiment of the resource scheduling method of the present invention is provided, where the resource scheduling method of this embodiment corresponds to the third embodiment of the resource scheduling apparatus, and a difference between this embodiment and the first embodiment of the resource scheduling method of the present invention is that the step S40 in this embodiment includes: when the current operating frequency is greater than the reference frequency and the current temperature reaches a first preset percentage of the core closing temperature, reducing the operating frequency of the central processing unit to the reference frequency;

In this embodiment, in the process of adjusting the operating frequency of the central processing unit, the mobile terminal compares the current operating frequency of the central processing unit with the reference frequency, and simultaneously compares the current temperature of the core with a preset core closing temperature, if the current operating frequency is greater than the reference frequency and the current temperature reaches a first preset percentage of the core closing temperature, it indicates that the current temperature of the core is fast reaching the core closing temperature, and at this time, the operating frequency of the central processing unit is reduced to the reference frequency, so that the core temperature is gradually reduced. The first preset percentage of the core shutdown temperature may be set to 90% of the core shutdown temperature, and of course, the first preset percentage may also be set according to actual conditions. If the current operating frequency is less than or equal to the reference frequency or the current temperature does not reach the first preset percentage of the core closing temperature, the operating frequency of the central processing unit does not need to be adjusted, namely, the central processing unit maintains the current operating frequency.

After the operation frequency of the central processing unit is adjusted, acquiring the new temperature of the core, when the new temperature is reduced to a second preset percentage of the core closing temperature, indicating that the temperature difference between the current temperature and the core closing temperature is larger, and increasing the operation frequency of the central processing unit by a preset frequency value every second preset time so as to slowly increase the operation frequency of the central processing unit and enable the system to process more tasks. The second predetermined percentage of the core shutdown temperature may be set to 80% of the core shutdown temperature, and of course, the first predetermined percentage may also be set according to actual conditions. The second predetermined time and the predetermined frequency value can also be set according to the actual situation, for example, 50Hz is adjusted up every 1 minute. When the current operating frequency of the central processing unit is greater than the reference frequency and the current temperature of the core is greater than the core closing temperature, the operating frequency of the central processing unit is reduced to the reference frequency, and the operation is repeated in a circulating mode.

step S50, acquiring the total consumption amount of the mobile terminal resource every third preset time, and acquiring the temperature of the kernel in a specified time period when the total consumption amount is larger than the preset consumption amount;

When the total consumption is less than or equal to the preset consumption, the total consumption of the mobile terminal resources is less, and the reference frequency of the operation of the central processing unit does not need to be adjusted by acquiring the curvature of the temperature change of the inner core.
