  Now, the mobile phone 1 can execute a plurality of applications simultaneously. The application to be operated is executed in the foreground, and the execution screen (operation screen) is displayed on the display surface 3. The remaining applications are executed in the background without displaying the execution screen on the display surface 3.

  An application executed in the background periodically communicates with another device for data update or the like regardless of a user operation related to the application executed in the foreground.

  In addition, the mobile phone 1 can transmit and receive data to and from other devices by short-range wireless communication using various communication methods such as WiFi (registered trademark) and Bluetooth (registered trademark). The mobile phone 1 includes an application for short-range wireless communication for each communication method. Hereinafter, for convenience of description, an application for short-range wireless communication is referred to as a “communication application”. Each communication application is executed in the background, and periodically performs communication for searching for an access point regardless of a user operation related to the application executed in the foreground.

  When the amount of communication in such background communication (hereinafter referred to as “background communication”) increases, the power consumption of the battery increases.

  Therefore, in the present embodiment, communication restriction is automatically performed for unnecessary background communication. That is, in the present embodiment, a predetermined condition for restricting background communication is satisfied for each predetermined period that is periodically visited, and more specifically, for each day of the week or for a predetermined time period. It is determined whether or not there is. When it is determined that the predetermined condition is satisfied, background communication for a predetermined period is limited.

  The processing related to communication restriction is performed by the control unit 11 in FIG. In other words, a function for restricting communication is given to the control unit 11 by a program held in the storage unit 12, and communication restriction processing is executed by this function. In FIG. 2, functions for communication restriction realized by the control unit 11 are shown as a determination unit 21, a communication control unit 22, and a storage control unit 23 for convenience.

  Hereinafter, a specific example of the communication restriction process will be described.

<Example 1>
In the present embodiment, for each application installed in the mobile phone 1, the activation frequency in the foreground of each application in the past day of the week is determined for each day of the week. For each application, background communication on days of the week with low activation frequency in the past foreground is restricted.

  The storage unit 12 stores an activation history database 12a and a communication setting table 12b used for communication restriction processing.

FIG. 3A is a diagram showing the configuration of the activation history database 12a, and FIG. 3B is a diagram showing the configuration of the communication setting table 12b. The activation history database 12a stores the date and time when each application installed in the mobile phone 1 is activated in the foreground (hereinafter referred to as “activation date and time”). The communication setting table 12b stores the communication mode of background communication set by the communication restriction process for each application. The communication mode includes an unrestricted mode in which background communication is not restricted and a restricted mode in which background communication is restricted.

  The determination unit 21 determines the activation frequency of each application in the foreground in the past day of the week for each day of the week. For example, the determination unit 21 refers to the activation history database 12a for each application, and determines whether or not it has been activated in the foreground even on the same day of the week as the current day of the week in the past predetermined period (for example, three weeks). To do.

  For each day of the week, the communication control unit 22 uses an application that has a lower activation frequency in the foreground in the past day of the week, such as an application that has not been activated in the foreground for the predetermined period of the past. Restrict background communication. For example, the communication control unit 22 prohibits execution of background communication of the application by setting the communication mode of the application to the restriction mode.

  The storage control unit 23 executes activation date / time registration processing and registers the activation date / time of each application in the activation history database 12a.

  FIG. 4 is a flowchart showing activation date and time registration processing. The start date and time registration process is repeatedly executed while the mobile phone 1 is powered on.

  The storage control unit 23 determines whether any application is activated in the foreground (S101). For example, when an application that is being terminated (not activated) is activated, the application is activated in the foreground. Further, when a predetermined operation for starting an application running in the background is performed in the foreground, the application is started in the foreground.

  If any application is activated in the foreground (S101: YES), the storage control unit 23 determines whether the operation time of the application in the foreground is longer than a predetermined time (S102). Here, the predetermined time is a reference time for determining that the user has erroneously started the application, and is set to a short time such as several seconds, for example, 5 seconds.

  If the activated application is executed in the foreground even after a predetermined time has elapsed, the storage control unit 23 determines that the operation time is longer than the predetermined time (S102: YES), and determines the activation date and time of the application as the activation history. Register in the database 12a (S103).

On the other hand, if the activated application is terminated before the predetermined time has elapsed or is moved to the background, the storage control unit 23 determines that the operation time is shorter than the predetermined time (S102: NO), and the application Is not registered in the activation history database 12a.
By such processing, it is possible to prevent the activation of the application due to an erroneous operation of the user from being reflected in the determination of whether to limit the background communication.

  FIG. 5 is a flowchart showing the communication restriction process. The communication restriction process is repeatedly executed while the mobile phone 1 is powered on.

  The control unit 11 monitors whether the date has changed (S201). When the date changes (S201: YES), the control unit 11 selects an application to be referenced from the activation history database 12a (S202). The control unit 11 (determination unit 21) refers to the activation history database 12a, and the selected application has been executed in the foreground even once on the same day of the week as the current day in the past predetermined period, for example, the past three weeks. It is determined whether or not there is a problem (S203).

  If the selected application has been executed in the foreground even once on the same day of the week as the current day in the past predetermined period (S203: YES), the communication mode is limited mode in the control unit 11 (communication control unit 22). (S204: YES), the communication mode is set to the non-restricted mode (S205). If the communication mode is already the non-restricted mode (S204: NO), the non-restricted mode is maintained. In the communication setting table 12b, “unrestricted mode” is registered in the communication mode column of the selected application.

  On the other hand, if the selected application has never been executed in the foreground on the same day as the current day in the past predetermined period (S203: NO), the control unit 11 (communication control unit 22) has a communication mode of If the non-restricted mode is set (S206: YES), the communication mode is set to the restricted mode (S207). If the communication mode is already the restricted mode (S206: NO), the restricted mode is maintained. In the communication setting table 12b, “restricted mode” is registered in the communication mode column of the selected application.

  The control unit 11 determines whether or not all applications registered in the activation history database 12a have been referenced (S208). If the control unit 11 determines that all applications are not referenced (S208: NO), the control unit 11 returns to the process of step S202, and selects the application to be referred to next. The control unit 11 performs the processing from step S203 to S207 for the selected application. When the control unit 11 finishes referring to all the applications (S208: YES), the process ends.

  By executing the communication restriction process in this way, setting of the communication mode for the day is completed for all applications. The communication control unit 22 refers to the communication setting table 12b, and performs background communication for the application whose communication mode is set to the non-restricted mode when the timing of background communication arrives on that day. On the other hand, the communication control unit 22 does not perform background communication for an application whose communication mode is set to the restricted mode, regardless of whether the timing of background communication arrives on that day.

  Every time the date changes, that is, for each day of the week, a communication mode is set for all applications, and background communication is executed based on the set communication mode.

  FIG. 6 is a diagram illustrating an execution state of background communication in a certain week in a certain application.

  The usage frequency of an application may increase on a fixed day of the week due to various usage situations of the user. For example, there is a case where a schedule is registered using a schedule application on a predetermined day of the week.

  For example, as shown in FIG. 6, when the frequency of use of an application is high on Wednesday and Sunday and low on other days, the communication restriction process of this embodiment is performed, so that the application related to the application is performed on Wednesday and Sunday. Background communication such as data update is performed, and background communication is not performed on other days of the week.

  As described above, in this embodiment, for each application, the background communication related to the application is not executed on the day of the week when there is a low possibility that the application is used. Therefore, battery power consumption due to unnecessary execution of background communication can be suppressed.

<Modification 1 of Example 1>
In the above embodiment, when the restricted mode is set, background communication is not performed. However, it is not a complete restriction as described above, and a partial restriction may be performed as in the present modification. For example, the communication control unit 22 may reduce the frequency of background communication.

  For example, a communication process may be performed in which transmission is performed and background communication related to one is performed but background communication related to the other is not performed. FIG. 7A is a flowchart showing a communication process for restricting one of transmission and reception.

When the start timing of the background communication arrives (S301: YES), the communication control unit 22 determines whether the background communication is related to the transmission of data or the like or the background communication is related to the reception of data or the like ( S302). When it is transmission (302: transmission ), the communication control unit 22 starts background communication (S303). On the other hand, when it is reception (S302: reception ), the communication control unit 22 stops the background communication (S304). In contrast to the communication process of FIG. 7A, the communication control unit 22 may stop the background communication when it is transmission and start the background communication when it is reception.

  Further, a communication process for starting or stopping the background communication may be performed according to the time zone. FIG. 7B is a flowchart showing a communication process for restricting background communication according to a time zone.

  When the start timing of background communication arrives (S311: YES), the communication control unit 22 determines whether or not the current time is an odd time zone (S312). If the current time is an odd time zone (S312: YES), the communication control unit 22 starts background communication (S313). On the other hand, when the current time is an even time zone (S312: NO), the communication control unit 22 stops the background communication (S314). In contrast to the communication process of FIG. 7B, the communication control unit 22 stops the background communication when the current time is an odd time zone, and the current time is an even time zone. In some cases, background communication may be started.

  Furthermore, a communication process for starting or stopping the background communication may be performed according to the lighting state of the display unit 13. FIG. 8A is a flowchart illustrating a communication process for limiting background communication according to the lighting state of the display unit 13.

  When the start timing of background communication arrives (S321: YES), the communication control unit 22 determines whether or not the display unit 13 is lit (S322).

When the operation on the mobile phone 1 is not performed for a predetermined time, the display unit 13 is turned off. Therefore, when the display unit 13 is lit, the application is used because the user is using the mobile phone 1.

  When the display unit 13 is lit (S322: YES), the communication control unit 22 starts background communication (S323). On the other hand, when the display unit 13 is turned off (S322: NO), the communication control unit 22 stops the background communication (S324).

  Furthermore, a communication process for starting or canceling background communication may be performed according to the elapsed time after the mobile phone 1 is operated. FIG. 8B is a flowchart showing a communication process for restricting background communication according to the elapsed time after the mobile phone 1 is operated.

  When the start timing of background communication arrives (S331: YES), the communication control unit 22 determines whether or not it is within a predetermined time after an operation on the mobile phone 1 (S332).

  If it is not long after the mobile phone 1 is operated, the user may continue to use the mobile phone 1 and the application may be used.

  If it is within a predetermined time after the mobile phone 1 is operated (S332: YES), the communication control unit 22 starts background communication (S333). On the other hand, if the predetermined time has passed after the cellular phone 1 is operated (S332: NO), the communication control unit 22 stops the background communication (S334).

<Modification 2 of Example 1>
In the above embodiment, for each application, the frequency of starting the application in the foreground on each past day of the week is determined for each day of the week, and the communication mode of the application is set to the non-restricted mode or the restricted mode based on the determination result. It was done.

  In this modified example, in addition to the above-described determination condition, it is determined whether or not a period during which the application is not activated in the foreground (hereinafter referred to as “non-activation period”) exceeds a predetermined number of days. In the present modification example, the communication mode is set to the non-restricted mode, the first restricted mode, or the second restricted mode based on these two determination conditions. The first restriction mode is a communication mode in which the above-described partial restriction is performed, and the second restriction mode is a communication mode in which the above-described complete restriction is performed.

  FIG. 9 is a flowchart showing the communication restriction process. In the communication restriction process of this modification, the processes of steps S204 to S207 of the communication restriction process of the first embodiment shown in FIG. 5 are replaced with the processes of steps S211 to S218. In FIG. 9, illustration of the processes in steps S201, S202, and S208 is omitted.

  If the selected application has been executed in the foreground even once on the same day as the current day in the past predetermined period (S203: YES), the control unit 11 (determination unit 21) has a non-startup period of the predetermined number of days. It is determined whether (for example, 7 days) is exceeded (S211). If the non-activation period does not exceed the predetermined number of days (S211: NO), the control unit 11 (communication control unit 22) sets the communication mode other than the non-restricted mode to the non-restricted mode (S212: YES → S213). ). On the other hand, if the non-activation period exceeds the predetermined number of days (S211: YES), the control unit 11 (communication control unit 22) sets the communication mode other than the first restriction mode to the first restriction mode (S215). : YES → S216).

Even when the selected application has never been executed in the foreground on the same day as the current day in a predetermined period in the past (S203: NO), the control unit 11 (determination unit 21) has a predetermined non-startup period. It is determined whether or not the number of days has been exceeded (S214). If the non-activation period does not exceed the predetermined number of days (S214: NO), the control unit 11 (communication control unit 22) sets the communication mode other than the first restriction mode to the first restriction mode (S215: YES). → S216). On the other hand, if the non-activation period exceeds the predetermined number of days (S214: YES), the control unit 11 (communication control unit 22) sets the communication mode other than the second restriction mode to the second restriction mode (S217). : YES → S218).

According to this modified example, for each day of the week, the activation frequency of the application on the day of the week and the period during which the application is not activated in the foreground are determined, and background communication is performed based on the determination result. Since it restrict | limits finely, the power consumption by background communication can be suppressed more effectively.
<Example 2>
In this embodiment, one day is divided into time zones every hour or time zones every few hours. In this embodiment, for example, a day is divided into time zones every 4 hours. In this case, one day is divided into six time zones from 0 to 4 o'clock, 4 o'clock to 8 o'clock, 8 o'clock to 12 o'clock, 12 o'clock to 16 o'clock, 16 o'clock to 20 o'clock and 20 o'clock to 24 o'clock. .

  In the present embodiment, for each application installed in the mobile phone 1, the activation frequency in the foreground of each application in the past time zone is determined for each time zone. For each application, background communication in a time zone in which activation frequency in the foreground is low in the same time zone in the past is limited.

  Also in this embodiment, the activation history database 12a of FIG. 3A and the communication setting table 12b of FIG. 3B are used.

  The determination unit 21 determines the activation frequency in the foreground of each application in the past time period for each time period. For example, the determination unit 21 refers to the activation history database 12a for each application for each time period, and once in the foreground in the same time period as the current time period in the past predetermined period (for example, 3 days). It is determined whether or not it has been activated.

  In each time zone, the communication control unit 22 has an application whose activation frequency in the foreground in the past time period is lower than a predetermined frequency, for example, an application that has not been activated in the foreground for the predetermined time period in the past. Limit the background communication of that application.

  FIG. 10 is a flowchart showing the communication restriction process. The communication restriction process is repeatedly executed while the mobile phone 1 is powered on.

  The control unit 11 monitors whether the time zone has changed (S401). When the time zone changes (S401: YES), the control unit 11 selects an application to be referenced from the activation history database 12a (S402). The control unit 11 (determination unit 21) refers to the activation history database 12a, and the selected application is executed in the foreground even once in the same time zone as the current time zone in the past predetermined period, for example, the past three days. It is determined whether it has been performed (S403).

If the selected application has been executed in the foreground even once in the same time zone as the current time zone in the past predetermined period (S403: YES), the control unit 11 (communication control unit 22) has a communication mode of If the restriction mode is set (S404: YES), the communication mode is set to the non-restriction mode (S405). If the communication mode is already the non-restricted mode (S404: NO), the non-restricted mode is maintained.

  On the other hand, if the selected application has never been executed in the foreground at the same time zone as the current time zone in the past predetermined period (S403: NO), the control unit 11 (communication control unit 22) If the mode is set to the non-restricted mode (S406: YES), the communication mode is set to the restricted mode (S407). If the communication mode is already the restricted mode (S406: NO), the restricted mode is maintained.

  If the control unit 11 determines that all applications are not referenced (S408: NO), the control unit 11 returns to the process of step S402 and selects the application to be referred to next. The control unit 11 performs the processing from step S403 to S407 for the selected application. When the control unit 11 finishes referring to all the applications (S408: YES), the process ends.

  By executing the communication restriction process in this way, the setting of the communication mode for that time zone is completed for all applications. The communication control unit 22 refers to the communication setting table 12b, and performs background communication for the application whose communication mode is set to the non-restricted mode when the timing of background communication arrives in that time zone. On the other hand, the communication control unit 22 does not perform background communication for an application whose communication mode is set to the restricted mode, regardless of whether the timing of background communication arrives in the time zone.

  Every time the time zone changes, that is, for each time zone, the communication mode is set for all applications, and background communication is executed based on the set communication mode.

  FIG. 11 is a diagram illustrating the execution status of background communication on a certain day in a certain application.

  As in the case of the day of the week, the usage frequency of a certain application may become high during a predetermined time period depending on the usage status of the user. As an example, there is a case where an e-mail is confirmed using an e-mail application at a predetermined time.

  For example, as shown in FIG. 11, when the usage frequency of a certain application is high in the time zone from 12:00 to 16:00 and in the time zone from 20:00 to 24:00 and is low in the other time zones, the communication restriction process of this embodiment As a result, background communication such as data update related to the application is performed in the time zone from 12:00 to 16:00 and the time zone from 20:00 to 24:00, and background communication is performed in other time zones. Is not done.

  As described above, in this embodiment, for each application, the background communication related to the application is not executed in a time zone where the possibility that the application is used is low. Therefore, battery power consumption due to unnecessary execution of background communication can be suppressed.

<Example 3>
In the present embodiment, for each communication method of short-range wireless communication, the connection frequency to other devices by each communication method in the past day of the week is determined for each day of the week. For each communication application corresponding to each communication method, background communication for searching for an access point on a day of the week with a low connection frequency to other devices by each communication method is restricted.

The storage unit 12 stores a connection history database 12c and a communication setting table 12d used for communication restriction processing.

  12A is a diagram showing a configuration of the connection history database 12c, and FIG. 12B is a diagram showing a configuration of the communication setting table 12d. The connection history database 12c stores, for each communication method, the date and time (hereinafter referred to as “connection date and time”) when communication connection to another device was made by each communication method. The communication setting table 12d stores the search interval set by the communication restriction process for the communication application corresponding to each communication method. In the present embodiment, a first time (for example, 5 seconds) and a second time (for example, 1 minute) longer than the first time are set as search intervals.

  The determination unit 21 determines, for each day of the week, the connection frequency to another device using each communication method in the past day of the week. For example, the determination unit 21 refers to the connection history database 12c for each communication method for each day of the week, and to another device even once on the same day of the week as the current day of the week in the past predetermined period (for example, three weeks). It is determined whether or not the communication connection has been made.

  In each day of the week, the communication control unit 22 uses a communication application in which the connection frequency to the other device in the past corresponding communication method of the day of the week is lower than a predetermined frequency, for example, the other device according to the communication method corresponding to the day of the week. For a communication application that has never been connected to the communication, background communication of the communication application is restricted. For example, the communication control unit 22 sets the communication application search interval to the second time, thereby reducing the frequency of background communication for searching for the communication application.

  The storage control unit 23 executes connection date and time registration processing, and registers the connection date and time of each communication method in the connection history database 12c.

  FIG. 13 is a flowchart showing connection date and time registration processing. The connection date and time registration process is repeatedly executed while the mobile phone 1 is powered on.

  When communication connection with another apparatus is performed by any communication method (S501: YES), the storage control unit 23 determines whether or not the connection time in the communication connection is longer than a predetermined time (S502). . Here, the predetermined time is a time used as a reference for determining that the user has made a communication connection due to an erroneous operation, and is set to a short time such as several seconds, for example, 5 seconds.

  If the communication connection continues even after the predetermined time has elapsed, the storage control unit 23 determines that the connection time is longer than the predetermined time (S502: YES), and the connection date and time of the communication method is stored in the connection history database 12c. Register (S503).

  On the other hand, when the communication connection is interrupted before the predetermined time elapses, the storage control unit 23 determines that the connection time is shorter than the predetermined time (S502: NO), and registers the connection date and time of the communication method in the connection history database 12c. do not do. By such processing, it is possible to prevent a communication connection due to a user's erroneous operation from being reflected in the determination of whether or not to limit background communication.

  FIG. 14 is a flowchart showing the communication restriction process. The communication restriction process is repeatedly executed while the mobile phone 1 is powered on.

The control unit 11 monitors whether the date has changed (S601). When the date changes (S601: YES), the control unit 11 selects a communication method to be referred to from the connection history database 12c (S602). The control unit 11 (determination unit 21) refers to the connection history database 12c, and the communication connection to the other device by the selected communication method is the same as the current day of the week in the past predetermined period, for example, the past three weeks. It is determined whether or not it has been performed once a day (S603).

  When the communication connection to the other device by the selected communication method has been made even once on the same day of the week as the current day in the past predetermined period (S603: YES), the control unit 11 (communication control unit 22) If the search interval of the communication application corresponding to the selected communication method is set to the second time (S604: YES), the search interval is set to the first time (S605). If the search interval is already the first time (S604: NO), the first time is maintained. In the communication setting table 12d, “first time” is registered in the search interval column of the communication application corresponding to the selected communication method.

  On the other hand, when the communication connection to the other device by the selected communication method has never been performed on the same day of the week as the current day in the past predetermined period (S603: NO), the control unit 11 (communication control unit) 22) If the search interval is set to the first time (S606: YES), the search interval is set to the second time (S607). If the search interval is already the second time (S606: NO), the second time is maintained. In the communication setting table 12d, “second time” is registered in the search interval column of the communication application corresponding to the selected communication method.

  The control unit 11 determines whether or not all communication methods registered in the connection history database 12c have been referred to (S608). If the control unit 11 determines that all communication methods are not referenced (S608: NO), the control unit 11 returns to the process of step S602 and selects the communication method to be referred to next. The control unit 11 executes the processes of steps S603 to S607 for the selected communication method. The control part 11 will complete | finish a process, if reference to all the communication systems is completed (S608: YES).

  By executing the communication restriction process in this way, setting of the search interval for the day is completed for communication applications corresponding to all communication methods. The communication control unit 22 refers to the communication setting table 12d and performs background communication for access point search according to the set search interval. If the search interval is the first time, the communication control unit 22 performs background communication for the search at the first time interval. On the other hand, if the search interval is the second time, the communication control unit 22 performs background communication for the search at the second time interval.

  Every time the date changes, that is, every day of the week, a search interval is set for all communication methods of short-distance wireless communication, and background search communication is performed using the set search interval.

  As described above, in this embodiment, for each communication method of short-range wireless communication, on the day of the week when the connection frequency is low in the past and the possibility that communication connection by the communication method is low is performed by the communication application corresponding to the communication method. The access point is searched at a long search interval. Therefore, battery power consumption due to execution of background communication for unnecessary search can be suppressed.

  In this embodiment, when a communication connection to another device by a certain communication method has never been made in the past predetermined period, that is, when the connection frequency by the communication method is low, this communication method is supported. The search interval for communication applications is lengthened. However, the search interval may not be lengthened in this way, and background communication for search may not be performed.

<Modification of Example 3>
In the above-described embodiment, for each application, the connection frequency to the other device by the corresponding communication method for each past day of the week is determined for each day of the week. Based on the result of this determination, the search interval of the communication application is the first interval. Set to time or second time.

  In this modified example, in addition to the above-described determination conditions, it is determined whether or not a period in which communication connection to another apparatus using the corresponding communication method is not made (hereinafter referred to as “non-connection period”) exceeds a predetermined number of days. Is done. In this modified example, based on these two determination conditions, the search interval is set to the first time, the search interval is set to the second time, and the search is canceled. When the setting for canceling the search is made, the communication control unit 22 does not perform background communication for the search.

  FIG. 15 is a flowchart showing the communication restriction process. In the communication restriction process of this modification, the processes of steps S604 to S607 of the communication restriction process of the third embodiment shown in FIG. 14 are replaced with the processes of steps S611 to S618. In FIG. 15, illustration of the processes in steps S601, S602, and S608 is omitted.

  If the communication connection to the other device by the selected communication method has been made even once on the same day of the week as the current day in the past predetermined period (S603: YES), the control unit 11 (determination unit 21) Then, it is determined whether or not the non-connection period exceeds a predetermined number of days (for example, 7 days) (S611). If the non-connection period does not exceed the predetermined number of days (S611: NO), the control unit 11 (communication control unit 22) sets the search interval other than the first time to the first time (S612: YES → S613). ). On the other hand, if the non-connection period exceeds the predetermined number of days (S611: YES), the control unit 11 (communication control unit 22) sets the search interval other than the second time to the second time (S615: YES). → S616).

  When the communication connection to the other device by the selected communication method has never been executed in the foreground on the same day of the week as the current day in the past predetermined period (S603: NO), the control unit 11 (determination) The unit 21) determines whether or not the non-connection period exceeds a predetermined number of days (S614). If the non-connection period does not exceed the predetermined number of days (S614: NO), the control unit 11 (communication control unit 22) sets the search interval other than the second time to the second time (S615: YES → S616). ). On the other hand, if the non-connection period exceeds the predetermined number of days (S614: YES), the control unit 11 (communication control unit 22) sets the setting other than the search cancellation to the search cancellation (S617: YES). → S618).

  According to this modified example, for each day of the week, the connection frequency to another device using the corresponding communication method and the period during which communication connection to the other device using the corresponding communication method is not performed are determined. Based on the determination result, background communication for searching is more finely limited. Therefore, power consumption due to background communication can be more effectively suppressed.

Note that the communication connection can be resumed by a user operation or the like regarding the communication connection to another device by the communication method for which the search is stopped. For example, when an operation for an icon for switching on / off of the communication connection displayed on the home screen is received from the touch detection unit 14 , the control unit 11 (communication control unit 22) moves to another device based on the communication method corresponding to the icon. Restart the communication connection.

<Example 4>
In this embodiment, as in the second embodiment, one day is divided into hourly time zones or time zones of several hours. In the present embodiment, for example, as in the second embodiment, a day is a time zone every 4 hours, that is, 0:00 to 4 o'clock, 4 o'clock to 8 o'clock, 8 o'clock to 12 o'clock, 12 o'clock to 16 o'clock. It is divided into six time zones from 16:00 to 20:00 and 20:00 to 24.

  In the present embodiment, for each communication method of short-range wireless communication, the connection frequency to other devices by each communication method in the past time zone is determined for each time zone. For each communication application corresponding to each communication method, background communication for searching for an access point in a time zone in which the frequency of connection to another device by each communication method is low is restricted.

  Also in this embodiment, the connection history database 12c in FIG. 12A and the communication setting table 12d in FIG. 12B are used.

  The determination part 21 determines the connection frequency to the other apparatus by each communication system in the past time slot | zone for every time slot | zone. For example, the determination unit 21 refers to the connection history database 12c for each communication method for each time zone, and once in the same time zone as the current time zone in the past predetermined period (for example, 3 days). It is determined whether or not a communication connection to the device has been made.

  In each time zone, the communication control unit 22 uses a communication application in which the connection frequency to the other device by the communication method corresponding to the past time zone is lower than a predetermined frequency, for example, the communication method corresponding to the time zone. For a communication application that has never been connected to another device, background communication of the communication application is restricted.

  FIG. 16 is a flowchart showing the communication restriction process. The communication restriction process is repeatedly executed while the mobile phone 1 is powered on.

  The control unit 11 monitors whether the time zone has changed (S701). When the time zone changes (S701: YES), the control unit 11 selects a communication method to be referred to from the connection history database 12c (S702). The control unit 11 (determination unit 21) refers to the connection history database 12c, and the communication connection to the other device by the selected communication method is the current time zone in the past predetermined period, for example, the past three days. It is determined whether it has been performed even once in the same time zone (S703).

  When the communication connection to the other device by the selected communication method has been made even once in the same time zone as the current time zone in the past predetermined period (S703: YES), the control unit 11 (communication control unit) 22) If the search interval of the communication application corresponding to the selected communication method is set to the second time (S704: YES), the search interval is set to the first time (S705). If the search interval is already the first time (S704: NO), the first time is maintained.

  On the other hand, when the communication connection to the other device by the selected communication method has never been made in the same time zone as the current time zone in the past predetermined period (S703: NO), the control unit 11 (communication If the search interval is set to the first time (S706: YES), the control unit 22) sets the search interval to the second time (S707). If the search interval is already the second time (S706: NO), the second time is maintained.

  When the control unit 11 determines that all communication methods are not referred to (S708: NO), the control unit 11 returns to the process of step S702 and selects a communication method to be referred to next. The control unit 11 executes the processes of steps S703 to S707 for the selected communication method. The control part 11 will complete | finish a process, if reference to all the communication systems is completed (S708: YES).

  By executing the communication restriction process in this way, the setting of the search interval for that time zone is completed for communication applications corresponding to all communication methods. The communication control unit 22 refers to the communication setting table 12d and performs background communication for access point search according to the set search interval. If the search interval is the first time, the communication control unit 22 performs background communication for the search at the first time interval. On the other hand, if the search interval is the second time, the communication control unit 22 performs background communication for the search at the second time interval.

  Every time the time zone changes, that is, for each time zone, a search interval is set for all communication methods of short-distance wireless communication, and background search communication is performed based on the set search interval.

  As described above, in this embodiment, for each communication method of short-range wireless communication, a communication application corresponding to the communication method is used in a time zone in which the connection frequency is low in the past and communication connection by the communication method is low. Thus, an access point search is performed at a long search interval. Therefore, battery power consumption due to execution of background communication for unnecessary search can be suppressed.

  In the present embodiment, as in the third embodiment, when the communication connection to another device by a certain communication method has not been performed once in the past predetermined period, the search interval is not increased, but the search interval is increased. The background communication for may not be performed.

<Others>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications can be made to the embodiments of the present invention in addition to the above. is there.

  For example, in the first embodiment, as an example of determining the activation frequency of the application in the foreground on each day of the week, it is determined whether the application has been activated even once in the foreground on the same day of the week as the current day of the week in the past predetermined period. It was. However, the present invention is not limited to this, and it may be determined whether or not the number of times that the application has been activated in the foreground on the same day as the current day in the past predetermined period is equal to or more than a predetermined number of times.

  Similarly, in the second embodiment, it may be determined whether or not the number of times the application is started in the foreground in the same time zone as the current time zone is a predetermined multiple times or more in the past predetermined period. . Further, also in the third embodiment, whether or not the number of times that the communication connection to the other device by the corresponding communication method is performed on the same day of the week as the current day in the past predetermined period is a predetermined plural number or more. May be determined. Furthermore, also in the fourth embodiment, the number of times that the communication connection to another device using the corresponding communication method is performed in the same time zone as the current time zone in the past predetermined period is a predetermined multiple times or more. It may be determined whether or not.

  Furthermore, the user may be allowed to set an application for which background communication is not automatically restricted as an application to be excluded.

  FIG. 17 is a diagram illustrating an example of a screen for the user to set an application to be excluded.

As shown in FIG. 17A, an exclusion region R is formed in a partial region of the home screen on which icons IC for starting applications are arranged. As illustrated in FIG. 17B, when the user performs an operation for moving a desired icon IC to the exclusion region R with a finger, the control unit 11 moves the icon IC to the exclusion region R. As a result, the control unit 11 sets an application corresponding to the icon IC moved to the exclusion area R as an application to be excluded. The control unit 11 always maintains the communication mode in the non-restricted mode for the application to be excluded, and does not limit the background communication.

  Note that, by copying the icon IC, a plurality of icon ICs corresponding to the same application may be arranged on the home screen. In this case, when one of the plurality of icon ICs corresponding to the same application moves to the exclusion area R, the remaining icon ICs other than the moved icon IC may also move to the exclusion area R. Alternatively, the remaining icon IC may be deleted. Furthermore, the display state of the remaining icon IC may change, for example, a background region having the same color as the exclusion region R may be formed around the remaining icon IC. Furthermore, the operation to the remaining icon IC may be invalidated so that the application is not activated even if the remaining icon IC is operated.

  Furthermore, in Example 2 and Example 4, each time slot | zone is set to the same length, However, At least one part time slot | zone may be set to a different length from another time slot | zone.

  Furthermore, the present invention can also be applied to a foldable mobile phone. In this case, as a partial limitation of the background communication described in the first modification of the first embodiment, if the mobile phone is in an open state when the start timing of the background communication arrives, the background communication is performed. If it is started and the mobile phone is in a closed state, a communication process for stopping the background communication may be performed.

  Furthermore, the present invention is not limited to searching for an access point during short-range wireless communication, but may be applied to a search for a reception standby state in PTT (Push To Talk) or the like. Here, the reception standby state is a state in which a search for a signal for starting a PTT call from another terminal is periodically performed to determine whether or not the terminal has received the signal via the PTT server. In this reception waiting state, when the connection frequency of the PTT call is low in the same time zone in the past or on the same day, the search interval in the same time zone or the same day may be increased. According to the above configuration, it is possible to suppress unnecessary power consumption in a standby state for a PTT call.

  The present invention is not limited to a mobile phone, and can be applied to various mobile terminal devices such as a PDA (Personal Digital Assistant), a tablet PC (Tablet PC), and an electronic book terminal.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
