Description

  The present invention relates to an information processing apparatus, a status notification method, and a status notification program.

  In recent years, information processing apparatuses equipped with a multitasking OS (Operating System) capable of executing a plurality of tasks simultaneously have increased. One example of a multitask OS is a smartphone. Unlike conventional information processing devices, even when the backlight of the LCD screen is turned off, each task of an application program (hereinafter referred to as an app) synchronizes data with the server device, and wireless communication occurs. Since the number of times also increases, the amount of signals to be processed by the base station increases, increasing the load on the base station and the mobile communication network. In addition, a plurality of smartphones may communicate at the same time, and this also causes a phenomenon in which the load on the base station or the mobile communication network temporarily increases.

  As one of the causes of such communication concentration, there is a state notification by which the information processing apparatus notifies the notification destination of the state change information regarding the state change. An information processing device that performs status notification causes a change in status at the same timing among a plurality of devices due to, for example, synchronization with a server or operation by specifying an absolute time in the device. It starts at the same time on multiple devices. Here, for example, as a technique for performing status notification in the information processing apparatus, Non-Patent Document 1 discloses a mechanism for receiving notification of a type of status change designated in advance by a task.

BroadcastIntent, BroadcastReceiver (http://developer.android.com/guide/components/intents-filters.html)

  However, if the mechanism disclosed in Non-Patent Document 1 is used, if the app has a program that activates a task upon notification of a state change, a state change that occurs at a specific time or an external communication There is a concern that a task may be activated simultaneously in a plurality of information processing devices due to a notification due to a state change that occurs in response to a change in the environment, which may cause a concentration of communication.

  The present invention has been made to solve such a problem, and an object thereof is to provide an information processing apparatus, a state notification method, and a state notification program capable of reducing an increase in processing load due to state notification. .

  In order to achieve the above object, an information processing apparatus according to the present invention is an information processing apparatus that notifies state change information related to a state change to a notification destination, a detection unit that detects a state change caused by a task, and a detection The acquisition unit acquires the acquisition unit that acquires the behavior type of the task that is the source of the state change detected by the unit, and the notification method of the state change information related to the state change detected by the detection unit. Notification means for determining based on the behavior type of the task that is the occurrence source of the state change, and notifying the state change information of the state change information based on the determined notification method.

  In the information processing apparatus according to the present invention, the detection unit detects a state change generated by a task, and the acquisition unit acquires the behavior type of the task that is the source of the detected state change. Then, the notification means determines a notification method to the notification destination of the state change information regarding the detected state change based on the acquired behavior type of the task that is the source of the state change, and the determined notification method The state change information is notified to the notification destination based on the above. In this way, since the notification method of the state change information regarding the detected state change is determined based on the behavior type of the task that is the source of the state change, for example, when it is a specific behavior type By avoiding or delaying the notification, it is possible to reduce an increase in processing load concentrated at a specific time due to the status notification.

  If the behavior type is a global synchronization type indicating that the behavior type is a task that is likely to be executed at a specific time, notification of state change information to the notification destination may be avoided. For example, in a plurality of information processing apparatuses, when a change in state caused by a task whose behavior type is a global synchronization type is notified to the notification destination, and the notification destination performs processing based on the notification, the processing is performed simultaneously. This increases the processing load. According to this configuration, when a task whose behavior type is a global synchronous type is a state change occurrence source, in order to avoid notification of state change information to the notification destination, processing at the notification destination is not performed, and the state notification is performed. The increase in the processing load due to can be reduced.

  When the behavior type is a global synchronization type indicating that the behavior type is a task that is likely to be executed at a specific time, the notification unit may notify the state change information with a delay to the notification destination. For example, in a plurality of information processing apparatuses, when a change in state caused by a task whose behavior type is a global synchronization type is notified to the notification destination, and the notification destination performs processing based on the notification, the processing is performed simultaneously. This increases the processing load. According to this configuration, when a task whose behavior type is a global synchronization type is a state change occurrence source, the state change information is delayed to the notification destination, for example, for a different time for each device, so that each device can be notified. The timing of the process at the notification destination changes, and the increase in processing load due to the status notification can be reduced.

  The notification means notifies the notification destination of instruction information for controlling the processing of the notification destination together with the state change information, when the behavior type is a global synchronization type indicating that the task is easily executed at a specific time. It is good. For example, in a plurality of information processing apparatuses, when a change in state caused by a task whose behavior type is a global synchronization type is notified to the notification destination, and the notification destination performs processing based on the notification, the processing is performed simultaneously. This increases the processing load. According to this configuration, when a task whose behavior type is a global synchronization type is a state change occurrence source, in order to notify the notification destination of instruction information for controlling the processing of the notification destination together with the state change information, By notifying the instruction information not to execute, processing at the notification destination is not performed, and an increase in processing load due to status notification can be reduced.

  When the notification type is a global synchronization type indicating that the behavior type is a task that is likely to be executed at a specific time and the notification destination is communicable, notification of state change information to the notification destination is avoided. Alternatively, the state change information may be notified to the notification destination with delay, or the instruction information for controlling the communication of the notification destination may be notified to the notification destination together with the state change information. According to this configuration, for example, in a plurality of information processing devices, when a state change generated by a task whose behavior type is a global synchronization type is notified to the notification destination, and the notification destination performs processing based on the notification, Processing is performed at the same time, which causes communication concentration. According to this configuration, when a task whose behavior type is the global synchronization type is a state change occurrence source and the notification destination is communicable, the notification destination is avoided by avoiding notification of the state change information to the notification destination. The communication timing is not executed, or the status change information is delayed and notified to the notification destination, the processing timing at the notification destination changes, or the instruction information for controlling the communication at the notification destination is sent together with the status change information to the notification destination. For example, by notifying instruction information indicating that communication processing is not performed, communication processing at the notification destination is not performed, and communication concentration due to state notification can be reduced.

  When the state change information is notified to the notification destination by the notification unit, the notification unit further includes a communication history holding unit that holds, as a communication history, whether or not communication has occurred based on the notification at the notification destination. Whether or not the notification destination is communicable may be determined based on the communication history held by the communication history holding means. According to this configuration, it is possible to more accurately determine whether the notification destination is communicable based on the past communication history.

  The notification means is a global synchronization type indicating that the behavior type is a task that is likely to be executed with a bias toward a specific time, and that the state change is designated in advance as being out of control and the notification destination is in advance In the case where it corresponds to at least one of those designated as non-control targets, the state change information may be notified to the notification destination. With this configuration, for example, by specifying in advance a state change that is known to cause no communication at the notification destination even if notification is made, even if the task is a global synchronous type, Since the change information is notified to the notification destination, it is possible to operate even a task based on the behavior of the conventional apparatus. In addition, with this configuration, for example, by specifying a notification destination task that is known not to cause communication at the notification destination even if notification is made, the task is designated as a global synchronous type. Even in such a case, since the state change information is notified and only a process that does not cause communication is executed in the notification destination task, it is possible to operate even a task based on the behavior in the conventional apparatus.

  When the time at which the execution of the task is reserved is an absolute time based on the real time for the task that is the source of the state change detected by the detection unit, the acquisition unit sets the behavior type to a specific time. It may be acquired as a global synchronization type indicating that the task is biased and easily executed. With this configuration, the determination as to whether or not the behavior type is the global synchronization type is made more specific.

  The notification means cannot acquire the behavior type of the task that is the source of the state change by the acquisition means, and if the state change detected by the detection means corresponds to a preset state change, The behavior type may be a global synchronization type indicating that the task is likely to be executed at a specific time. With this configuration, even when the behavior type cannot be acquired by the acquisition unit, the behavior type can be appropriately determined.

  The notifying means acquires an existing notifying means for notifying the notification destination of state change information related to the state change detected by the detecting means, and a notifying method for notifying of the state change information related to the state change detected by the detecting means. And a notification control unit that determines based on the behavior type of the task that is the source of the state change acquired by the control method, and controls notification by the existing notification unit based on the determined notification method. Good. With this configuration, the present invention can be easily applied to an existing information processing apparatus including an existing notification unit.

  By the way, the present invention can be described as an invention of an information processing apparatus as described above, and can also be described as an invention of a status notification method and a status notification program as follows. This is substantially the same invention only in different categories, and has the same operations and effects.

  That is, the state notification method according to the present invention is a state notification method executed by the information processing apparatus that notifies the notification destination of state change information related to a state change, and detects a state change caused by a task, An acquisition step for acquiring the behavior type of the task that is the source of the state change detected in the detection step, and a notification method to the notification destination of the state change information regarding the state change detected in the detection step are acquired in the acquisition step. And a notification step of determining based on the behavior type of the task that is the generation source of the state change and notifying the state of the state change information based on the determined notification method.

  Further, the state notification program according to the present invention includes a detection unit that detects a state change caused by a task, and an acquisition unit that acquires a behavior type of the task that is the source of the state change detected by the detection unit. The notification method for determining the notification method of the state change information related to the state change detected by the detecting unit is determined based on the behavior type of the task that is the source of the state change acquired by the acquiring unit, and the determined notification It is characterized by functioning as notifying means for notifying the destination of the state change information based on the method.

  According to the present invention, an increase in processing load due to state notification can be reduced.

  The storage device 16 is a storage means such as an EEPROM (Electronically Erasable and Programmable ROM) or a flash memory, and stores data, programs, and the like used for control by the control device 11. In addition, the storage device 16 stores data indicating a predetermined numerical value such as a threshold value used in the information processing device 10.

  The storage device 16 may include a removable storage means such as a removable medium, or a user (or information processing device 10) such as a UIM (User Identity Module) card or a SIM (Subscriber Identity Module) card. A storage unit in which data for identification is recorded may be included. Moreover, the data for identifying this user (or information processing apparatus 10) are memorize | stored in the external server, and the structure which the information processing apparatus 10 acquires by communication may be sufficient.

  The power control device 17 monitors the remaining amount of the battery and the external power supply, and controls the state of charge of the battery.

  The information processing apparatus 10 having the above configuration is, for example, a smartphone, but may be any information processing apparatus that executes a plurality of programs such as a mobile phone terminal, a tablet terminal, a personal computer, and a PDA (Personal Digital Assistant). In addition to the above configuration, the information processing apparatus 10 has a configuration equivalent to a general-purpose smartphone, such as a configuration for realizing a function of shifting to a power saving mode when a user operation is not performed continuously for a predetermined time. have. When the information processing device 10 is in the power saving mode, the display area of the display device 15 is turned off, but the control device 11 may be in an operating state in which processing is performed even in this state. In addition, the information processing apparatus 10 may include various sensors such as a vibrator and an acceleration sensor for detecting the inclination of the information processing apparatus 10.

  Based on the above-described hardware configuration, the information processing apparatus 10 is a server that changes the state in the apparatus, for example, the display area of the display apparatus 15 changes to a turned off state by processing of a certain program, or the communication apparatus 13. When a change in the state of the apparatus due to an external factor such as reception of communication from the apparatus 20 occurs, the state of the apparatus is notified to an application or an arbitrary task included in the application. In the following description, apps and tasks are unified and described as tasks. When described as a task, it indicates either or both of an application and a task. The task that receives the notification executes processing as necessary. In other words, the notification triggers the behavior of the notification destination. The process of notifying in response to such a change in the state of the apparatus is hereinafter referred to as “state notification process”.

  The state change in the device includes the change in the state of the remaining battery level monitored by the power supply control device 17 and the presence / absence of external power supply, in addition to turning on and off the display area of the display device 15, and the storage device. 16 may include a change in the attach / detach state of the removable storage unit 16 or a change in the state that occurs inside the information processing apparatus 10 such as addition or deletion of a stored application.

  The information processing apparatus 10 stores in advance designation of the type of state change that the task wants to receive notification (hereinafter referred to as “reception notification type”), and when the state change occurs, the corresponding state change Is notified to a task for which notification is specified (hereinafter referred to as “notification destination task”). This eliminates the need for the task to determine whether or not processing is required for unnecessary notifications. When there are multiple notification destination tasks, there are a method of notifying all the notification destination tasks of the status change at once, and a method of giving notifications to each notification destination task in order based on the priorities specified in advance. Whether to use the method is determined according to the type of state change. Note that the priority order is not limited to statically determined in advance, but dynamically depending on the status of the notification destination task, such as the length of time until the processing of the notification destination task is completed and the amount of communication that has occurred. You may decide. The notification destination task also has a communication type included in attribute information corresponding to a task identifier that is information for identifying each application or one or more tasks included in each application, in the same manner as the notification source. Specifically, the communication type included in the attribute information corresponding to the task identifier of the notification destination task includes information indicating whether or not communication occurs due to the notification of the state change.

  Here, a supplementary explanation of the attribute information included in the task is provided. The attribute information included in the task is stored in the storage unit 102 or the like in association with the task identifier of the task. The attribute information includes a behavior type, a receipt notification type, a priority, and a communication type. Note that the attribute information may not include either one or both of the priority and the communication type.

  As described above, the tasks have a relationship of notifying each other. The task can be notified from the outside of other tasks and terminals, and can be notified to the outside of other tasks and terminals.

  The information processing apparatus 10 receives a process started at a specific time (hereinafter referred to as “specific time process”) or receives information distributed all at once through a communication network (hereinafter referred to as “broadcast reception”). The state change is notified to the corresponding notification destination task and executed in a concentrated manner. The information processing apparatus 10 performs processing for distributing the processing of the notification destination task that is executed in such a concentrated manner. The information processing apparatus 10 stores a plurality of programs (state notification programs) for executing the above-described specific time processing and notification destination task processing in the storage device 16. The control device 11 executes these programs and controls each device shown in FIG. 2, thereby realizing the function shown in FIG.

  FIG. 3 is a block diagram illustrating a functional configuration realized by the information processing apparatus 10. The information processing apparatus 10 includes a detection unit 101 (detection unit), a notification unit 103 (acquisition unit, notification unit), and a storage unit 102 (acquisition unit).

  The detection unit 101 is a detection unit that detects a state change caused by a task, such as a state change of the device due to an internal factor or an external factor. The detection unit 101 is a function realized by the control device 11, the voice input / output device 12, the communication device 13, the operation device 14, and the power supply control device 17, for example. Specifically, the detection unit 101 detects these state changes by the following method.

  The control device 11 is supplied with a signal for notifying the input / output state from the voice input / output device 12 when a voice input from the outside or a voice output to the outside is generated. Based on this notified signal, the control device 11 (detection unit 101) detects, for example, that the sound output has changed from a silent state to a state in which some sound is being reproduced.

  Note that the voice input / output device 12 may supply the control device 11 with a signal notifying the connection state of the external device in a configuration in which an external device for voice input / output can be connected to the information processing device 10. In this case, the control device 11 (detection unit 101) detects that the external device has changed from an unconnected state to a connected state, for example.

  The control device 11 is supplied with a signal for notifying the communication state from the communication device 13 that receives communication from the outside. Based on this notified signal, the control device 11 (detection unit 101) detects, for example, that the communication has changed from an incommunicable state to a communicable state.

  In addition, as a communication state, the control device 11 (detection unit 101) may detect that a state in which specific data is received from the communication network via the server device 20 has occurred. This is, for example, reception of an e-mail or reception of a voice call start instruction using the voice input / output device 12.

  The control device 11 is supplied with an operation signal from the operation device 14 operated by the user. Based on this notified signal, the control device 11 (detection unit 101) detects, for example, that a specific button provided in the information processing device 10 has changed from a non-pressed state to a pressed state.

  In addition, not only a physical button but the touch to a touch sensor and the input of specific operation on a touch panel may be detected.

  Further, the control device 11 is supplied with a signal for notifying the power supply state from the power supply control device 17 that monitors the power supply state. Based on this notified signal, the control device 11 (detection unit 101) detects that the battery has changed from a charged state to a discharged state, for example, in a configuration in which the information processing device 10 includes a battery. In addition, the control device 11 (detection unit 101) may detect that the connection state to the external power source has changed or that the remaining battery level has changed.

  The control device 11 (detection unit 101) discriminates the task that caused the state change with respect to the state change caused by executing the task program in the control device 11, for example, the start of communication processing or the lighting of the display area. To do. In the information processing apparatus 10, for example, the timer application includes an alarm task having a function of notifying that the set time has been reached by turning on the display area at a time set in advance by the user and generating an alarm sound. If the display area is lit by an alarm task, the controller 11 (detects that the task that caused the state change is an alarm task included in the timer application in response to the detected state change. Part 101) detects.

  As described above, the detection unit 101 detects a change in the state of the apparatus due to internal or external factors.

  The storage unit 102 is a storage unit that stores the receipt notification type of each task. For example, the storage unit 102 is a function realized by the control device 11 and the storage device 16 in cooperation. Specifically, the storage unit 102 stores these receipt notification types by the following method.

  In the information processing apparatus 10, when a new task is installed, the control apparatus 11 has a plurality of information processing apparatuses 10 that receive notification types, priorities, and processes for each task based on attribute information included in the task. The behavior type indicating whether it is likely to be executed at a specific time is determined. Information indicating that the task is a task that is likely to be executed biased to a specific time in a plurality of information processing devices 10 as a behavior type (hereinafter referred to as “global synchronization type”), or times distributed in the plurality of information processing devices 10 There is information (hereinafter referred to as “global asynchronous type”) indicating that the task is easy to be executed. Examples of tasks that are of the global synchronization type include a task designated to communicate with the server device 20 at 0:00 every day to synchronize data, and a plurality of information processing devices 10 simultaneously from the server device 20. There is a task that receives a notified notification. On the other hand, as a task that is a global asynchronous type, a user starts an operation of the information processing device 10 and starts an operation in response to a state change in the operation device 14, or a random number is used to synchronize data. There is a task designated to communicate with the server device 20 at the generated time.

  In addition to the two types of behavior, the global synchronous type and the global asynchronous type, in the information processing apparatus 10, a task that is executed synchronously according to the behavior of a certain task may be distinguished as an intra-terminal synchronous type.

  The storage device 16 (storage unit 102) corresponds to a table in which task identifiers and behavior types are associated (hereinafter referred to as “behavior type table”), task identifiers, receipt notification types, and priorities. The attached table (hereinafter referred to as “reception notification type table”) is stored, and the control device 11 adds the determined task identifier and behavior type to the behavior type table, and also receives the reception notification type, priority, and task identifier. Add to receipt notification type table. The receipt notification type table may not be associated with the priority.

  When the application is uninstalled, the holding information such as the corresponding task identifier is deleted from the behavior type table and the receipt notification type table.

  The receipt notification type table is not updated only when an application is installed or uninstalled, and the receipt notification type may be added, changed, or deleted at any time from the task being executed. As a result, the task does not receive unnecessary notifications, and the processing load can be reduced.

  Similarly, the behavior type may be changed at any time from the task being executed.

  As described above, the storage unit 102 stores the receipt notification type of each task.

  Further, a supplementary explanation will be given for the task identifier. Even if there are tasks for performing the same processing (for example, tasks for performing screen display) for a plurality of applications, each task has a different task identifier. That is, the same task identifier does not exist in a plurality of tasks.

  FIG. 8 shows an example of the behavior type table. In the behavior type table shown in FIG. 8, task identifiers and behavior types are stored in association with each other. Note that the behavior type table may manage the behavior type only in units of tasks, not in units of applications.

  FIG. 9 shows an example of the receipt notification type table. In the receipt notification type table shown in FIG. 9, the task identifier and the receipt notification type are stored in association with each other. As shown in FIG. 9, information for identifying a state change that a task wants to receive in advance as a receipt notification type, and information for identifying a task that causes a state change that a task wants to receive in advance (such as a task identifier) ), And information obtained by combining them may be stored.

  The notification unit 103 is a notification unit that notifies the task of state change information related to the state change detected by the detection unit 101. The notification triggers the task behavior. For example, the notification unit 103 is a function realized by the control device 11 and the storage device 16 in cooperation.

  The notification unit 103 may include an acquisition unit (not shown) that acquires task information such as attribute information such as a behavior type of a task that is a generation source of a state change detected by the detection unit 101 and a task identifier. . Then, the notification unit 103 sets the notification method of the state change information related to the state change detected by the detection unit 101 to the notification destination, such as the behavior type of the task that is the source of the state change acquired by the acquisition unit. The state change information is determined based on the information, and the state change information is notified to the notification destination based on the determined notification method. When the behavior type is a global synchronization type, the notification unit 103 may avoid notification of state change information to the notification destination. In the present embodiment, “notification of state change information” may be described as “notification of state change” for convenience.

  Specifically, the notification unit 103 notifies the state change by the following method.

  When detecting a state change by the detection unit 101, the control device 11 (notification unit 103) determines a task to be notified of the state change based on the receipt notification type table held in the storage unit 102 and notifies the notification. Do. At this time, when there are a plurality of notification destination tasks, the control device 11 (notification unit 103) notifies all the tasks all at once according to the state change, or when each task specifies the receipt notification type. It is also determined whether to perform notification sequentially based on the priorities.

  When performing notification all at once, the control device 11 (notification unit 103) simultaneously performs state notification processing for all notification destination tasks regardless of priority. When the notification is performed sequentially, the priority of all the notification destination tasks is compared by the control device 11 (notification unit 103), the notification destination task having the highest priority is notified, and the notification destination task After completion of the process at, the notification destination task having the next highest priority is notified, and finally the state notification process is completed when the processing of the notification destination task with the lowest priority is completed. When there are a plurality of notification destination tasks having the same priority, the control device 11 (notification unit 103) determines which notification destination task has priority based on a predetermined condition. However, it may be indeterminate which is prioritized without setting conditions. Further, the control device 11 (notification unit 103) may assign priority based on a predetermined condition such as task identifier or type without explicitly specifying the priority.

  When the cause of the state change is accompanied by the task program execution, the control device 11 (notification unit 103) acquires the behavior type of the task that has caused the occurrence factor from the behavior type table, and performs state notification processing. Determine whether to do. For example, the notification unit 103 does not perform the state notification process on the notification destination task when the task that is the cause is the global synchronous type, and performs the state notification process when the task is the global asynchronous type. As a result, it is possible to prevent the status notification process from being performed at approximately the same time in the plurality of information processing apparatuses 10 and start the operation of the notification destination task, so that the communication process does not occur simultaneously for the server apparatus 20. Can be.

  As described above, the notification unit 103 notifies the task of a state change.

[Operation]
Based on the above configuration, the information processing apparatus 10 performs state notification processing. The status notification processing is repeatedly performed in parallel with the processing by other tasks after the information processing device 10 is turned on and a program for executing the status notification processing is started by the control device 11.

  Hereinafter, the basic form of the operation performed by the information processing apparatus 10 in the state notification process will be described with reference to FIG.

  FIG. 10 is a flowchart illustrating an example of a basic form of an operation performed by the information processing apparatus 10 in the state notification process. First, the information processing apparatus 10 acquires the current terminal state (step S1). When the information processing apparatus 10 determines that there is no change in the terminal state as compared with the terminal state acquired last time (step S2: NO), after a predetermined time (for example, 0.1 second) has elapsed. The operation of step S1 is performed again. When there is a change in the terminal state from the previously acquired terminal state (step S2: YES), it is determined whether the factor causing the change in the terminal state is due to the task (step S3). If the change in the terminal state does not depend on the task in step S3 (step S3: NO), the information processing apparatus 10 proceeds to step S6-1, refers to the receipt notification type from the state change, and notifies the notification destination. Notify the task. If the change in the terminal state is due to the task (step S3: YES), the task identifier of the task that caused the change in the terminal state is acquired (step S4). The behavior type corresponding to the task identifier is acquired from the behavior type table, and if the behavior type is a global synchronization type (step S5: YES), the process ends without performing notification to the notification destination task (step S6). -2). If the behavior type is other than the global synchronization type (step S5: NO), the process proceeds to step S6-1.

  Next, another operation performed by the information processing apparatus 10 in the state notification process will be described with reference to FIG. FIG. 4 is a flowchart illustrating another example of the operation performed by the information processing apparatus 10 in the state notification process. Steps S1 to S5 are the same as those in FIG.

  In FIG. 4, when step S3 is NO or step S5 is NO, it is determined whether the notification method of a state change is simultaneous notification (step S6). When the notification method of the state change is simultaneous notification in step S6 (step S6: YES), the information processing apparatus 10 is in a state for all the notification destination tasks that specify the state change as the receipt notification type. A change is notified (step S7). In addition, when the notification method of the state change is not simultaneous notification in step S6 (step S6: NO), the state is first set for the notification destination task having the highest priority among the notification destination tasks to be notified. A change is notified (step S8). If there is a notification destination task for which the state change notification has not been completed among the notification destination tasks in which the state change is specified as the receipt notification type (step S9: NO), the notification destination task that has already been notified is selected. The operation of step S8 is performed again for the excluded notification destination task. When the notification of the state change is completed for all the notification destination tasks that specify the state change as the receipt notification type (step S9: YES), the process is terminated.

[effect]
The timing at which each process of the task that has caused the state change and the notification destination task is executed when the information processing apparatus 10 executes the state notification process will be described.

  5, 6, and 11 are diagrams for explaining the timing at which the processing of each task is executed. 5, 6, and 11, a solid arrow indicates that a task is being executed, and a broken arrow indicates that a state change has been notified. In the state notification process, an information processing device that notifies even when the state change is caused by a task and the task is a global synchronization type (this is called a conventional device) Is changed, notification is performed as shown in FIG. 5 and the notification destination task is executed.

  In the conventional device, at time T1, the task AP2 that receives the communication U1 from the server device 20 starts processing. In the process of task AP2, the first state change is generated at time T2, and the second state change is generated at time T3. Similarly, at time T4, the task AP1 that receives the communication B1 from the server device 20 and receives the communication starts processing. In the process of task AP1, the first state change is generated at time T5, and the second state change is generated at time T6. The task AP3 is a process executed when the first state change occurs, and the task AP4 is a process executed when the second state change occurs, and the receipt notification type is designated in advance. When the task AP3 is notified of the first state change, the task AP3 executes processing for generating communication with the server device 20, receives the notification at the time T2, receives the communication U2 and receives the notification at the time T5, the communication U3. Occur.

  The communications U1, U2, and U3 are communications performed between a single information processing apparatus and the server apparatus 20, and the communications B1 are communications performed from a single server apparatus 20 to a plurality of information processing apparatuses. News communication. Accordingly, the communication U1 is performed at different times among the plurality of information processing apparatuses, and the communication B1 is performed at the same time among the plurality of information processing apparatuses.

  The task AP1 is assigned a global synchronization type behavior type in order to perform broadcast communication. It is assumed that tasks AP2, AP3, and AP4 are global asynchronous behavior types.

  In the conventional apparatus, when the task AP2 that receives the communication U1 at time T1 starts processing, and the first state change occurs at time T2 in this processing, the state change notification S1 is notified to the task AP3 and the processing is performed. Executed. In this process, communication U2 occurs in task AP3. Further, when the second state change occurs at time T3, a state change notification S2 is notified to the task AP4, and the process is executed. The task AP4 does not generate communication in the process. Since the generation time of the communication U1 is different among the plurality of information processing apparatuses, the generation time of the communication U2 is also different among the information processing apparatuses, and it is difficult for the server apparatus 20 to generate congestion and a rapid increase in processing load.

  Further, the communication B1 is a broadcast communication, and the task AP1 that has received the communication B1 at the time T4, which is the same time among a plurality of information processing apparatuses, starts processing, and in this processing, the first state change at time T5. When this occurs, the state change notification S3 is notified to the task AP3, and the process is executed. Similarly, when the second state change occurs at time T6, a state change notification S4 is notified to the task AP4, and the process is executed. For this reason, the time at which the communication U3 occurs is also substantially the same in the plurality of information processing devices, and the concentration of communication increases the occurrence of congestion in the server device 20 and the peak processing load.

  On the other hand, when the terminal state changes with the execution of the task, the information processing apparatus 10 performs notification as shown in FIG. 6 and the notification destination task is executed. In the information processing apparatus 10, when the task AP2 that has received the communication U1 at time T1 starts processing, and the first state change occurs at time T2 in this processing, the behavior type of the task AP2 that causes the state change However, since it is not a global synchronization type, notifications S1 and S2 of state change are notified to the tasks AP3 and AP4 as in the conventional device, and the tasks AP3 and AP4 behave similarly to the conventional device.

  Further, when the task AP1 that has received the communication B1 at time T4 starts processing, and the first state change occurs at time T5 in this processing, the behavior type of the task AP1 that causes the state change is referred to, and the global Because of the synchronous type, notification of a state change is not performed to the notification destination tasks AP3 and AP4. Therefore, neither task AP3 nor AP4 is executed, and no communication occurs. That is, it is possible to avoid the occurrence of congestion in the server device 20 and reduce the processing load peak.

  As described above, in the information processing apparatus 10, in the state notification processing, the state change is caused by the task, and the notification is not performed when the task is the global synchronization type. Avoid the occurrence of congestion and reduce the processing load peak.

  FIG. 11 is a modified version of FIG. In FIG. 11, when the task AP1 that has received the communication B1 at time T4 starts processing, and the second state change occurs at time T6 in this processing, the behavior type of the task AP1 that causes the state change is referred to. Judge that it is a global synchronous type. However, referring to the communication type of the notification destination task AP4, the task AP4 determines that communication does not occur in the process, and notifies the notification destination task AP4 of the state change notification S4.

  Subsequently, a state notification program 70 for causing a computer to execute the above-described series of processing by the information processing apparatus 10 will be described. As shown in FIG. 7, the status notification program 70 is inserted into a computer and accessed, or stored in a program storage area 81 formed in a recording medium 80 provided in the computer.

  The status notification program 70 includes a detection module 700 and a notification module 701. Functions realized by executing the detection module 700 and the notification module 701 are the same as the functions of the detection unit 101 and the notification unit 103 of the information processing apparatus 10 described above.

  Part or all of the status notification program 70 may be transmitted via a transmission medium such as a communication line, and received and recorded (including installation) by another device. Further, each module of the status notification program 70 may be installed in any one of a plurality of computers instead of one computer. In this case, the above-described series of status notification program 70 is performed by a computer system composed of the plurality of computers.

[Modification]
The above-described embodiment is merely an example of implementation of the present invention, and may be modified as follows. Moreover, you may implement combining embodiment mentioned above and each modification shown below as needed.

(Modification 1)
When determining the behavior type, the storage unit 102 not only specifies the task attribute information and the behavior type by the task that is being executed, but also specifies the designated time when the task is periodically executed and the future execution time is designated. You may judge from the designation method. When there is a high possibility that the designated time and the designation method of the execution time are the same time among the plurality of information processing apparatuses 10, the global synchronous type is determined, and the other tasks are determined as the global asynchronous type. For example, the task is to set the time exactly at the specified time such as 0:00 with the intention of executing the process when the date changes, or “every day 06:38”, but not at the correct time. A task that always sets the same time every time is determined to be a global synchronous type. Further, if the execution time designation method is a task that uses absolute time designation based on a calendar or a clock instead of relative time designation such as the elapsed time from the start time of the information processing apparatus 10, it is determined as a global synchronous type. May be.

  The determination of the behavior type may be performed in cooperation with the server device 20 without being performed only in the storage unit 102. In this case, the information processing apparatus 10 transmits the execution time set by each task to the server apparatus 20, and the server apparatus 20 includes a certain number or more of information processing apparatuses among the execution times received from the plurality of information processing apparatuses 10. A task for which the execution time specified in 10 is set is determined to be a global synchronization type. The server device 20 transmits the determination result to the information processing device 10.

  In the above description, the storage unit 102 performs the global synchronization type determination. However, the acquisition unit may perform the determination. Specifically, for the task that is the source of the state change detected by the detection unit 101, the acquisition unit, when the time when the execution of the task is reserved is an absolute time based on real time, May be acquired as a global synchronization type.

(Modification 2)
When determining the behavior type, the storage unit 102 may use not only the task attribute information and the specification of the behavior type by the task being executed, but also the behavior type table transmitted from the server device 20. The server device 20 holds the determination result of the behavior type of each task in advance as a behavior type table, and transmits the behavior type table in response to a request from the storage unit 102.

(Modification 3)
The notification unit 103 is responsible for tasks that do not generate communication during processing (hereinafter referred to as “non-communication tasks”) among the notification destination tasks even when the task that caused the state change is a global synchronous type. Notification of a state change may be performed. Thereby, it is possible to maintain the behavior of the non-communication task in the conventional apparatus while avoiding the occurrence of congestion in the server apparatus 20 and suppressing the peak processing load. Whether or not the task is a non-communication task is determined from the attribute information included in the task, but if the attribute information alone cannot be determined, a status change notification is sent, and a history of whether communication has occurred at that time (communication history) ) May be determined by holding a communication history holding unit (not shown) (communication history holding means). That is, when the notification unit 103 notifies the notification destination of the state change information, the communication history holding unit holds, as a communication history, whether or not communication has occurred at the notification destination based on the notification. Then, the notification unit 103 determines whether or not the notification destination task can communicate based on the communication history held by the communication history holding unit.

  In the case of non-communication task processing, when operating in cooperation with another task, it is also determined whether another task operating in cooperation generates communication. Notification may not be performed even for a task.

(Modification 4)
Even when the task that caused the state change is a global synchronization type, the notification unit 103, for example, designates that the state change has been designated as not subject to control in advance and the notification destination is not subject to control in advance. If it corresponds to at least one of the designated items, the state change information may be notified to the notification destination. As a matter of course, notification of state changes not designated in advance is controlled. With this configuration, for example, by specifying in advance a state change that is known to cause no communication at the notification destination even if notification is made, even if the task is a global synchronous type, Since the change information is notified to the notification destination, it is possible to operate even a task based on the behavior of the conventional apparatus. In addition, with this configuration, for example, for a notification destination task for which it is known that communication does not occur at the notification destination even when notification is performed, the notification unit 103 is designated as a task identifier that is not subject to control in advance. Because the communication type is referred to, the presence or absence of communication is determined, and even if the task is a global synchronous type, the state change information is notified, and only the process that does not cause communication is executed in the notification destination task. It is possible to operate even a task premised on the behavior of the conventional apparatus.

(Modification 5)
The notification unit 103 may notify the state change with a delay by a randomly generated time even when the task that caused the state change is a global synchronization type. As a result, communication occurs due to the processing of the notification destination task, but the timing at which communication occurs among the plurality of information processing apparatuses 10 is dispersed. Therefore, it is possible to avoid the occurrence of congestion in the server apparatus 20 and the peak processing load. It is possible to maintain the behavior of the conventional apparatus while keeping the value small.

(Modification 6)
Even when the task that caused the state change is a global synchronous type, the notification unit 103 specifies that the communication at the notification destination task is cut off for a certain period of time, and then notifies the state change. (For example, the notification destination is notified together with the state change information that specifies that the communication in the notification destination task is blocked for a certain period of time). As a result, communication is attempted by the processing of the notification destination task, but the communication is actually cut off, so that the occurrence of congestion in the server device 20 can be avoided and the peak of the processing load can be reduced. . Instead of specifying that communication be cut off, the start of communication may be specified to be delayed by a randomly generated time. Further, it may be specified to control the processing in the notification destination task instead of specifying to block communication. For example, when the behavior type is the global synchronization type, the notification unit 103 may notify the notification destination of instruction information for controlling the processing of the notification destination together with the state change information.

(Modification 7)
When the behavior type is the global synchronization type and the notification destination is communicable, the notification unit 103 avoids the notification of the state change information to the notification destination or notifies the notification destination of the state change information with a delay. Alternatively, instruction information for controlling communication at the notification destination may be notified to the notification destination together with the state change information.

(Modification 8)
The storage unit 102 may determine the behavior type in the notification unit 103 without determining the behavior type. Specifically, if the task that caused the state change cannot be detected, or if the behavior type is not set for the task that caused the state change, the state change determined in advance by the state change of the terminal detected by the detection unit 101 If this is true, the behavior type of the task that caused the state change is regarded as the global synchronization type. In this configuration, the storage unit 102 may not have the behavior type table. If the task causing the state change cannot be detected, the task displayed in the display area is regarded as the task causing the state change.

  Further, even a task that is not accompanied by display in the display area may be regarded as a task that causes a state change as long as it is a task that specifies the state change notification as a receipt notification type.

  Even when a task is considered to be a global synchronous type when the state change occurs, the task that caused the state change ends or disappears from the display area, and the state change occurs. When a certain time has elapsed since the current time and when a predetermined state change occurs (for example, the display area is turned off), the behavior type of the task that is subsequently operated (considered to be a global synchronous type) is set to the global You may consider it asynchronous.

  The detection unit 101 includes a detection unit in the existing technology that does not acquire the task that caused the state change, and the storage unit 102 stores the storage unit in the existing technology that holds the receipt notification type table and the behavior that holds the behavior type table. The notification unit 103 is configured so as to discard the notification unit in the existing technology that does not change the notification method according to the behavior type and the notification distributed from the notification unit according to the behavior type. And a notification control unit that performs the above.

  FIG. 12 is a block diagram illustrating a functional configuration realized by the information processing apparatus 10a according to the present modification. Compared with each unit shown in FIG. 3, the information processing apparatus 10a includes a detection unit 106 in the existing technology that does not acquire the task that caused the state change, a storage unit 107 in the existing technology that holds the receipt notification type table, and a behavior type table. A behavior type storage unit 108 to be held, a notification unit 104 (existing notification unit) and a notification control unit 105 (notification control unit) in the existing technology that do not change the notification method according to the behavior type.

  The notification control unit 105 controls notifications sequentially performed among notifications distributed from the notification unit 104 in the existing technology. However, the present invention is not limited to this, and notifications that are performed simultaneously may be controlled. As a specific control procedure, the notification unit 104 in the existing technology notifies the notification destination of state change information related to the state change detected by the detection unit 101, and the notification control unit 105 detects the state detected by the detection unit 101. The notification method of the state change information related to the change is determined based on the behavior type of the task that is the source of the state change acquired by the acquisition unit, and the notification in the existing technology is performed based on the determined notification method The notification by the unit 104 is controlled.

  The notification control unit 105 registers the reception notification type in the same manner as other tasks, but the priority at that time is set to a value higher than that of all other notification destination tasks, so that the notification from the notification unit 104 in the existing technology is notified. Receives the action type of the task that caused the state change first, and if it is a global synchronization type, cancels the notification to the notification unit 104 in the existing technology so that the notification is not distributed to the notification destination task Execute the process. On the other hand, in the case of the global asynchronous type, the notification unit 104 in the existing technology is notified to the next highest priority task.

  Note that the control of the notification control unit 105 not only executes the process of canceling the notification in the case of the global synchronization type, but also waits for a randomly generated time before giving priority to the notification unit 104 in the existing technology. Notifications to the notification destination task may be performed in descending order.
