Description

  The present invention relates to an apparatus, a distribution server, and a method for evaluating power consumption of an application.

  Recent communication terminals not only perform communication, but also can download and execute various applications from a server. Specific examples of the communication terminal include a mobile phone, an information terminal, a smartphone, and a notebook personal computer, but are not limited thereto. The number of applications that can be downloaded to a communication terminal has been steadily increasing, and the range of both users and developers who are application creators has expanded.

  Today, applications with various functions exist on the market. The power consumption of these applications varies greatly depending on hardware resources used by the applications, application mounting methods, and the like. The length of time that the application can be used in the communication terminal and the power consumption consumed by the application are in a trade-off relationship, and the power consumption of the application is an important factor for the communication terminal. In particular, in the case of a wireless communication terminal such as a mobile phone, power consumption is important. For example, if an application is introduced without knowing that there is a large amount of power consumption, the usage time of the communication terminal may be significantly reduced unexpectedly, reducing the motivation for the user to use various applications. There is concern.

  The power consumption of the communication terminal can be calculated according to the amount of hardware resources used in the communication terminal (see Non-Patent Document 1 for this point). The usage amount depends on a program operating on a communication terminal such as a CPU usage rate and a wireless communication throughput, and a usage amount does not depend on a program such as a luminance of an LCD backlight. As described above, since power consumption is an important factor for the communication terminal, it is desirable to provide a measure for power consumption when a provider recommends an application to a user. Although the technique of Non-Patent Document 1 shows that power consumption can be calculated from the usage rate of hardware resources, it does not calculate power consumption by an application. Therefore, in the conventional technology, the application is not recommended to the user in consideration of the power consumption by the application.

  An object of the present invention is to enable a distribution server to recommend an application to a user in consideration of power consumption by the application.

An apparatus according to one embodiment is:
An apparatus for evaluating the power consumption of an application executed on a communication terminal,
A receiving unit that receives, from a plurality of users, a report signal including identification information of an executed application, information on an execution state of the application, and information on the amount of resources used by executing the application. When,
A receiving unit for receiving a request signal including identification information of a certain application and identification information of a communication terminal from a certain user;
A power consumption calculation unit that calculates a power consumption value for each execution state by applying the resource usage information to a predetermined calculation formula for each execution state of the application;
Based on the calculated power consumption value, an application consumption comprising: a transmission unit that transmits a response signal including information on power consumption when the certain application is introduced into the communication terminal of the certain user to the certain user. It is a device for evaluating electric power.

  According to one embodiment, the distribution server can recommend an application to the user in consideration of power consumption by the application.

  In general, the distribution server according to the present embodiment collects usage information of hardware resources when an application is executed from each communication terminal in the communication system. The distribution server holds a formula (power evaluation formula) that evaluates the power consumption on the communication terminal of the application from the hardware resource usage information (model parameter), and estimates the power consumption from the collected resource usage information To do. From the collected model parameters on a large number of communication terminals, the distribution server statistically determines a power consumption value representing each application. When receiving the search request from the communication terminal, the distribution server also transmits the calculated power consumption value in addition to the meta information of the application included in the search result. As a result, it is possible to effectively reduce the risk of introducing an application with unexpectedly high power consumption without the user's knowledge.

<1. Communication system>
FIG. 1 shows a communication system 1 used in the embodiment. The communication system 1 includes a plurality of communication terminals 10a, 10b, 10c (collectively referred to as “10”), a distribution server 20, an application management server 30, and a communication network 40. For the sake of illustration, only three communication terminals are depicted, but the number of communication terminals is arbitrary. The communication terminal 10 communicates with the distribution server 30 via the communication network 40. The distribution server 20 communicates with the application management server 30 as necessary. The application management server 30 has an application that can be provided by a service provider, and provides the application in response to a request from the distribution server 20. In general, the communication network 40 includes a wireless network and a wired network. The communication network 40 may be any appropriate communication network that enables communication between the communication terminal and the distribution server.

<2. Communication terminal>
FIG. 2 shows a functional block diagram of the communication terminal 10 and the distribution server 20. FIG. 2 shows various functional elements provided in the communication terminal 10 and the distribution server 20 that are particularly relevant to the present embodiment. The communication terminal 10 may be any appropriate communication terminal that can download and execute an application from the distribution server. Specifically, the communication terminal 10 is a mobile phone, an information terminal, a smartphone, a tablet terminal, a laptop computer, or the like, but is not limited thereto.

  The illustrated communication terminal 10 includes at least a resource usage management unit 101, a resource usage storage unit 102, an execution state management unit 103, a transmission / reception unit 104, a display unit 105, and an application management unit 106.

  The resource usage management unit 101 manages to what extent the applications being executed on the communication terminal 10 are using various hardware resources constituting the communication terminal 10. The resource usage includes, for example, CPU usage rate, throughput at the network interface in the communication terminal (that is, the amount of data transmitted and received), the amount of data read from the recording medium (storage) built in the communication terminal, the communication terminal The amount of data read from the recording medium (storage) that is detachably attached, the amount of data written to the internal or external recording medium, the GPS usage time, the Bluetooth usage time, etc. It is not limited to. Note that the resource usage information includes information on the transition of the application execution state in addition to the application start time and end time. The resource usage management unit 101 acquires these resource usage statuses at arbitrary time intervals and records them in the resource usage storage unit 102.

  FIG. 3 illustrates the resource usage stored in the resource usage storage 102. As illustrated, various items (CPU usage time, etc.) related to resource usage are stored for each application. The application is identified by application identification information (application ID).

  The execution state management unit 103 in the communication terminal 10 in FIG. 2 monitors the execution state of the application installed on the communication terminal 10, and notifies the resource usage management unit 102 as soon as there is a change. For example, there are three application execution states. The first is a “front operation” state, which occupies the front of the display screen, accepts input from the user, and displays information. The second is the state of “backward movement”, which has contents to be displayed on the display screen, but is hidden behind other applications and desktops, etc., and cannot be input or presented by the user. is there. The third is a “resident operation” state where there is no content to be displayed on the display screen, but it is constantly operating behind. An application typically has one or more of these states. The application execution state continues to operate in any state except when the user explicitly instructs it or when the system garbage collector forcibly terminates the currently operating process to secure resources.

  The transmission / reception unit 104 transmits / receives signals to / from the distribution server 20 via the communication network 40. For example, information recorded in the resource usage storage unit 102 is reported to the distribution server 20. In addition, information recommending some application to the user and an application selected by the user are transmitted from the distribution server 20 to the communication terminal 10. In addition, a search request signal for requesting presentation of a list of applications that match a specific condition is transmitted from the communication terminal 10 to the distribution server 20. Further, the resource usage information (resource history information) is reported from the communication terminal 10 to the distribution server 20 at a certain frequency or as necessary (in response to an instruction from a user or an operator).

  The display unit 105 functions as a visual user interface. Specifically, the display unit 105 is a liquid crystal display (LCD), a plasma display, an organic EL panel, or the like, but is not limited thereto. The display unit 102 in the present embodiment realizes a touch screen having a touch-sensitive transparent panel, and can control the display of the screen by the movement of the user's finger or stylus. The display unit 102 can display characters, figures, symbols, still images, moving images, and the like. For example, an icon representing an application is displayed on the screen. Note that the communication terminal 10 may be provided with not only a visual user interface such as the display unit 105 but also other user interfaces. For example, a keypad, a control panel, a keyboard, a touchpad, a mouse, a trackball, a microphone, a speaker, and the like may be provided.

  The application management unit 106 manages applications installed in the communication terminal 10, acquires information on a list of installed applications as necessary, and transmits the information to the distribution server via the transmission / reception unit 104. .

<3. Distribution server>
The distribution server 20 includes at least an application list reception unit 201, a resource usage amount reception unit 202, a power consumption calculation unit 203, a search unit 204, a transmission unit 205, a power consumption storage unit 206, and a resource usage amount storage unit 207. The distribution server 20 includes a similarity calculation unit 208 as necessary.

  The application list receiving unit 201 receives information acquired by the application management unit 106 (information on a list of applications installed in the communication terminal 10) from various users under the communication system.

  The resource usage receiving unit 202 receives information recorded in the resource usage storage 102 from the communication terminal. The received information is stored in the resource usage storage unit 207.

  The power consumption calculation unit 203 calculates the power consumption of each application using the information stored in the resource usage storage unit 207 and records it in the power consumption storage unit 206. The power consumption calculation unit 203 calculates an evaluation value (P__estimated) of the power consumption of the communication terminal using a power consumption evaluation model (power consumption evaluation formula). The power consumption evaluation model (power consumption evaluation formula) is a model for deriving an evaluation value of power consumption from model parameters. The model parameter represents an operation state (for example, CPU load factor) of a predetermined component constituting the hardware of the communication terminal 10 and may or may not depend on the terminal model. As an example, the evaluation value (P_estimated) of power consumption is calculated by the following equation.

ここで、「Pi」は、消費電力モデルのパラメータ（例えば、CPU負荷率等であり、モデルパラメータという）の値を示し、「ci」は、各モデルパラメータの係数（電力係数）を示し、「N」は、モデルパラメータの総数を示す。「i」は、モデルパラメータを識別する番号を示し、1〜Nの整数である。上記の数式において、Pi各々の値を入力値として与えることで、評価値（P＿estimated）が出力値として出力される。消費電力算出部203は、あらかじめ、トレーニングベンチにより通信端末10の機種別に、電力係数ciを導出して保持している。消費電力算出部33は、リソース使用量受信部202が受信したモデルパラメータの値から、通信端末各々における消費電力を算出し、消費電力格納部206に記録する。

Here, “Pi” indicates a value of a parameter of the power consumption model (for example, a CPU load factor or the like and is referred to as a model parameter), “ci” indicates a coefficient (power coefficient) of each model parameter, “N” indicates the total number of model parameters. “I” indicates a number for identifying a model parameter, and is an integer from 1 to N. In the above formula, by giving each value of Pi as an input value, an evaluation value (P_estimated) is output as an output value. The power consumption calculation unit 203 derives and holds the power coefficient ci in advance for each model of the communication terminal 10 using the training bench. The power consumption calculation unit 33 calculates the power consumption in each communication terminal from the value of the model parameter received by the resource usage reception unit 202 and records it in the power consumption storage unit 206.

  The search unit 204 can generate a list of applications that match the search request condition from the communication terminal 10 and include the information recorded in the power consumption storage unit 206 as a search target.

  The transmission unit 205 transmits a signal to the communication terminal via the communication network 40. The transmitted information includes, for example, a list of search results created by the search unit 204.

<4. Example of operation>
<4.1 Acquisition of resource usage information>
FIG. 4 shows an operation when the communication terminal 10 collects resource usage information (model parameter) information and reports it to the distribution server 20. Such an operation is performed by all communication terminals under the communication system. FIG. 4 shows the operation from when one application is started until it is terminated. This operation can be performed independently for the application installed in the communication terminal 10. However, it is necessary to appropriately reduce the frequency of information collection and reporting so that the power consumed due to operations such as collecting resource usage information and reporting collected information does not increase excessively. There is. In addition, even when there are a large number of applications used for information collection and reporting, the number of applications to be used needs to be appropriately reduced.

  In step S11, the execution state management unit 103 detects that an application has started operating on the communication terminal 10. When the application starts operation, when the user explicitly instructs to start, when the communication terminal starts (in the case of an application set to start operation when the communication terminal starts), other Examples include, but are not limited to, when called from an application by some trigger.

  In step S12, the execution state management unit 103 notifies the resource usage management unit 101 that the operation has started. The notification is performed by transmitting, to the resource usage management unit 101, information indicating the process ID allocated due to the operation of the application and information indicating that the operation of the application has been started. The process is a program for executing processing by the CPU of the communication terminal 10, and the process ID is assigned by the system of the communication terminal 10.

  In step S13, the resource usage management unit 101 starts monitoring the designated process in response to the notification from the execution state management unit 103. The resource usage state by the process is recorded as a snapshot at a certain moment. Therefore, the resource usage management unit 101 needs to collect snapshot information at some time interval in order to acquire time-series data. The shorter the time interval, the more accurately it will be possible to record temporal changes, but the resources consumed for the process of acquiring usage information, recording and reporting to the distribution server will increase. The frequency, reporting frequency, and the number of applications that collect and report information are suitably small and limited.

  If the execution state of the application has changed in step S14, the change in the execution state is detected by the execution state management unit 103. For example, the application may move from “front operation” to “rear operation” by the user's operation, or conversely, may move from “rear operation” to “front operation”.

  In step S15, the execution state management unit 103 notifies the resource usage management unit 101 that a change in the operation state has been detected. This notification is performed by transmitting information indicating the process ID and information indicating that the operation state of the application has changed to the resource usage management unit 101.

  In step S16, the execution state management unit 103 detects the end of the application. As described above, the application is terminated by an explicit operation by the user, a system garbage collector, or the like.

  In step S17, the execution state management unit 103 notifies the resource usage management unit 101 that the application has ended. This notification is performed by transmitting information indicating the process ID and information indicating that the application is terminated to the resource usage management unit 101.

  In step S18, the resource usage management unit 101 ends the monitoring of the notified process.

  In step S19, the resource usage management unit 101 notifies the resource usage storage unit 102 of the application ID, activation state, and resource usage information of the application in the monitored process. The application ID is identification information (ID) for uniquely identifying an application in the distribution server 20.

  In step S20, the resource usage storage unit 102 records the notified information. Data based on this information is recorded as time-series data. Information recorded in the resource usage storage unit 102 is also referred to as resource usage history information. As shown in FIG. 3, the resource usage history information includes a user for uniquely identifying a user on the communication system in addition to the information on the resource used, the terminal model name, the start time, the state transition time, and the end time. Contains the ID.

<4.2 Calculation of power consumption>
FIG. 5 shows an operation flow when the distribution server 20 calculates power consumption from the resource usage history of each application. The resource usage history information is resource usage information stored in the resource usage storage unit 102.

  In step S21, the resource usage receiving unit 202 receives the resource usage history of the application recorded by the communication terminal 10 in step S20, and records it in the resource usage storage 207. As shown in FIG. 3, the resource usage history information includes a user for uniquely identifying a user on the communication system in addition to the information on the resource used, the terminal model name, the start time, the state transition time, and the end time. Contains the ID.

  In step S22, the power consumption calculation unit 203 substitutes the resource usage history information (model parameter) into the power consumption evaluation formula for each communication terminal, and consumes when the application is used in the communication terminal. The average power consumption is calculated. The average is done for various users. Further, the average value of power consumption is calculated for each execution state of the application. As described above, when there are three application execution states, for example, “front operation”, “back operation”, and “always operation”, an average value of power consumption is calculated for each of these states. For example, in FIG. 6, “expected power consumption” output from the power consumption calculation unit 203 is calculated for each of the three operating states.

  In step S23 of FIG. 5, the distribution of the average value of power consumption in the execution environment of each user is analyzed. If the distribution is a unimodal distribution that shows only one peak, the value that represents the distribution, such as the average value or the mode, is the power consumption value as the representative power consumption value for the application. It is recorded in the storage unit 206 (step S25).

  On the other hand, when the distribution shows multimodality having two or more peaks, the resource usage tendency is analyzed in step S24. If there are two or more peaks, the usage and environment of the application may be different for each user. For example, in the application of a music player that plays music, when using wired earphones directly connected to a communication terminal for viewing and when using Bluetooth for wireless viewing, the resource usage of the communication terminal is used. The amount can vary. Alternatively, even if the resource usage method is the same, the resource usage amount may vary depending on the radio wave intensity of the communication network at the time of executing the application, the user terminal operation speed, and the like. Such a situation may appear as a plurality of peaks. In step S24, it is determined whether or not there is such a possibility.

  In step S26, when a difference in resource usage tendency around each of the plurality of peaks in the power consumption distribution appears clearly, each peak value is recorded as a representative value, and at that time, the type of resource used is also recorded. (Step S27). Accordingly, for example, when Bluetooth is used, 0.5 W is consumed, and when not used, 0.3 W is consumed, which can be presented to the user. As described above, when the user understands the power consumption for each usage method, it is possible to select an application after understanding the degree of use of the power consumption.

  When the difference in the resource usage tendency between the peaks is not clear, it is considered that the difference is a simple execution environment. Therefore, as in the case of the unimodal distribution, a single representative value is recorded (step S25). ).

  As shown on the right side of FIG. 6, for example, assume that user M sends a search request to distribution server 20 for application A. Note that in FIG. 6, elements of the distribution server 20 other than the power consumption calculation unit 20 and the search unit 204 are omitted. The user M has not yet introduced the application A into his / her communication terminal, but intends to determine whether or not to install the application A based on the search result. In response to the search request, the distribution server 20 extracts the terminal model information of the user M and the identification information of the application A from the search request, and calculates a power consumption evaluation value (P_estimated) for the terminal model. The evaluation value (P_estimated) is calculated for each operation state. The distribution server 20 notifies the user M of information on the evaluation value (P_estimated) of power consumption as a search result. Thereby, the user M can know how much power is consumed when the application A is introduced into his terminal model. Then, after understanding the power consumption, the user M can determine whether or not to install the application A.

  Further, the search request from the communication terminal can include parameters such as “power consumption ascending order” or “power consumption descending order”, in addition to the search keyword such as terminal model information and application ID. In response to this, the distribution server 20 can arrange the calculated evaluation values (P_estimated) of the power consumption in the “power consumption ascending order” or “power consumption descending order”. As a result, the user can search for applications suitable for the purpose in order of power consumption.

<5. First Modification>
As described above, according to the present embodiment, it is possible to notify the user of the power consumption of the application. The distribution server according to the first modified example of the embodiment notifies the user of an estimate of how long it can be used on the communication terminal when the user actually installs the application. Such a guide may be notified instead of the value of power consumption itself, or may be notified together with the value of power consumption.

  Using the representative power consumption value of each application recorded in step S25 or S27 of FIG. 5, the distribution server determines the communication from the information of all the applications installed on the communication terminal that transmitted the search request. The executable time on the terminal is calculated. For example, when almost no application has been introduced to the communication terminal 10 and the application is introduced, the time that the communication terminal can be used is expected to be relatively long. However, when many applications have already been installed in the communication terminal 10, if more applications are installed, it is expected that the time during which the communication terminal can be used is relatively short. In this way, the amount of power resource allocation differs according to the number of applications installed in the communication terminal 10, and the terminal usable time after the application is installed varies.

  When generating a search request, the communication terminal 10 transmits information including a list of applications installed on the communication terminal 10 from the transmission / reception unit 104. Information of a list of applications installed in the communication terminal 10 is stored in the application management unit 106. The application list reception unit 201 of the distribution server 20 receives information on the list of installed applications from the communication terminal 10 together with the search request, and refers to the power consumption value of the target application from the power consumption storage unit 206.

  The distribution server 20 uses the power consumption information indicating the evaluation value (P_estimated) of the power consumption of the application and the application list information to calculate the executable time when the application is introduced into the communication terminal. The power consumption storage unit 206 records the power consumption value for each execution state of the application, such as front operation, rear operation, and resident operation.

By the way, the communication terminal 10 always consumes power as long as the power is turned on regardless of the execution state of the application. The power consumption for such an offset is P_offset, and the power consumption of the application in each operation state (front operation, back operation, resident operation) in the communication terminal is P_fore, P_back, and P_service. P_offset is not an application distributed from the distribution server, but is a power consumption caused by an operating system (OS) and middleware operating on the communication terminal 10, and takes a specific value for each model of the communication terminal. These values can be obtained or calculated in advance. As the application executable time, the continuous use time that mainly indicates the time during which the “front operation” can be performed continuously and the continuous standby time that is the start time of the communication terminal when there is no user operation There are two. If the battery capacity of the communication terminal is C [Wh], the continuous usage time is
C ÷ (P_fore + P_service + P_offset) [h]
Can be calculated. Continuous standby time is
C ÷ (P_back + P_service + P_offset) [h]
Can be calculated.

  When calculating the continuous usage time and continuous standby time according to the search request, set P_fore to the value of the application to be searched and P_service to the value of the application installed on the communication terminal and the value of the application to be searched The distribution server can obtain the continuous use time and the continuous standby time together with the search result. However, P_back is set to 0 for convenience because it depends on whether the user starts the application. By using these pieces of information, the distribution server can present information on the continuous use time and continuous standby time of each application on the communication terminal that transmitted the search request.

  In addition to the application startup state on the communication terminal acquired by the execution state management unit 103 and the power consumption information of the application stored in the power consumption storage unit, the remaining battery level is measured on the communication terminal. It is also possible to present the available time.

  In addition to notifying the user of the continuous usage time and continuous standby time when the application is introduced, it is also advantageous to compare the continuous usage time and continuous standby time before and after the application is introduced. For example, before introducing an application, the continuous usage time is XXX time, but when it is installed, the user can be notified that the information is XXX time, so that the user can easily understand the display. can do.

<6. Second Modification>
The distribution server 20 according to the second modification includes a similarity calculation unit 208 that calculates the similarity between applications. As a method for calculating the degree of similarity between applications, there are a method by collaborative filtering that evaluates the co-occurrence degree between applications based on the purchase tendency and activation tendency of the application, a method by text analysis using the meta information of the application, and the like. The similarity may be calculated by any appropriate method known in the art.

  In addition to receiving a search request from the communication terminal 10, the distribution server 20 also receives information on a list of applications installed in the communication terminal 10. The distribution server 20 enumerates (lists up) applications having a high degree of similarity with each application included in the list. The distribution server 20 discriminates among the listed applications that have lower power consumption than the applications installed on the communication terminal 10. For example, applications A0, B0, C0 are included in the list, applications A1, A2, A3, A4 with high similarity to application A0 are B1, B2 with applications with high similarity to application B0. Suppose that In this case, the distribution server 20 calculates the power consumption of the applications A1, A2, A3, and A4. If the power consumption of the application A1 is lower than the power consumption of the application A0, the application A1 is recommended to the user. . Further, the distribution server 20 calculates the power consumption of the applications B1 and B2, and if the power consumption of the application B2 is lower than the power consumption of the application B0, the application B2 is recommended to the user. In this way, by examining the power consumption of an application similar to the application that the user already owns, it is possible to recommend an application that consumes less power than the current application.

  According to the embodiment of the present invention, the usage amount of the hardware resource according to the execution state of the application in the communication terminal is collected from various communication terminals and analyzed in the distribution server, thereby reducing the power consumption for each application. A guideline can be calculated, and information can be searched and recommended using the information.

  According to the embodiment of the present invention, the user can know the standard of the power consumption when the application is used in his / her communication terminal without actually executing the application on the communication terminal. Therefore, as a result of actually installing and using an application that consumes a lot of power, the power consumption increases significantly, the time that the communication terminal can be used is unexpectedly shortened, and the waste that would eventually be uninstalled is eliminated. be able to. When uninstalling, the application is searched again. However, according to the present embodiment, the trouble of searching for the application again can be saved. By introducing the mechanism according to the present embodiment, it is possible to realize a kind of management function that prevents an application from being introduced into an environment that is not appropriate for the application. By exhibiting such a management function, it is possible to prevent applications that should not be downloaded from being downloaded in vain. The evaluation of such applications will decline, and as a result, only applications that can be truly utilized by the user will remain in the market and can be expected to eventually be deceived as preferred applications. As a result, the level of applications and developers in the market is raised, and the market can be activated and the use expanded.

  Although the present invention has been described with reference to particular embodiments, they are merely illustrative and those skilled in the art will appreciate various variations, modifications, alternatives, substitutions, and the like. . For example, the present invention may be applied to any appropriate mobile communication system that recommends applications to users. For example, the present invention includes W-CDMA system, HSDPA / HSUPA W-CDMA system, LTE system, LTE-Advanced system, IMT-Advanced system, WiMAX, Wi-Fi system, etc. May be applied. Although specific numerical examples have been described in order to facilitate understanding of the invention, these numerical values are merely examples and any appropriate values may be used unless otherwise specified. Although specific mathematical formulas have been described to facilitate understanding of the invention, these mathematical formulas are merely examples, unless otherwise specified, and any appropriate mathematical formula may be used.
