Description

  The present invention relates to a mobile communication terminal apparatus and a mobile communication terminal apparatus control method.

  The mobile communication terminal device operates with a built-in rechargeable battery. In order to charge the rechargeable battery, it is necessary to connect to a fixed power source. Thus, when connected to a fixed power source, inconveniences such as being unable to carry the mobile communication terminal device occur. Therefore, it is preferable that the user can use the mobile communication terminal device without performing charging for as long as possible. However, rechargeable batteries have a fixed charge capacity. Therefore, in order to extend the operation time, it is required to reduce power consumption during operation. As a response to such a demand for reducing power consumption, when there is a function that is not used, it is preferable to efficiently control the power supply without interfering with the operation of the user. Here, as functions that are not required to be used continuously, for example, WiFi (registered trademark), Bluetooth (registered trademark), mobile communication network connection function, GPS (Global Positioning System), and LCD (Liquid Crystal Display) display function and so on.

  The following conventional techniques have been proposed for such power control. For example, by using location information obtained from WiFi access point location information or GPS location information acquisition function or mobile communication network base station information, the location information is determined, and the power supply according to the registration information at a pre-registered location Conventional techniques for performing control have been proposed. In addition, a conventional technique has been proposed in which a function to be activated for each application to be used is registered or learned and power control is performed based on the registered or learned information. Further, a conventional technique for learning the behavior of a vehicle at a specific position on a road and performing the same operation at the same place has been proposed.

  However, in the conventional technology that performs power control according to the registration information at a pre-registered position, it is necessary to register the control contents in advance, which complicates the registration procedure and effectively restricts power consumption. It was difficult. In addition, the registration procedure is similarly complicated even in the conventional technique in which a function to be activated for each application to be used is registered. Furthermore, it is difficult to reduce the power consumption by the power control in the conventional technology in the car.

  The disclosed technology has been made in view of the above, and an object thereof is to provide a mobile communication terminal apparatus and a mobile communication terminal apparatus control method that can automatically register power control and efficiently reduce power consumption. And

  In one aspect of the mobile communication terminal device and the mobile communication terminal device control method disclosed in the present application, the location information acquisition unit acquires location information of the device itself. The power supply unit supplies power. The power consuming unit includes at least a wireless communication unit that performs wireless communication, and operates using power from the power supply unit. The condition storage unit stores the power usage state by the operation of the power consumption unit and the location information acquired by the location information acquisition unit in association with each other. When the position information acquired by the position information acquisition unit matches the position information stored in the condition storage unit, the power control unit is configured to use the power consumption so that a power usage state corresponding to the position information is obtained. Control part.

  According to one aspect of the mobile communication terminal apparatus and mobile communication terminal apparatus control method disclosed in the present application, it is possible to automatically register power control and to effectively reduce power consumption.

  Embodiments of a mobile communication terminal apparatus and a mobile communication terminal apparatus control method disclosed in the present application will be described below in detail with reference to the drawings. The mobile communication terminal apparatus and mobile communication terminal apparatus control method disclosed in the present application are not limited by the following embodiments. Examples of the mobile communication terminal device include a mobile phone and a PDA (Personal Data Assistant).

  FIG. 1 is a block diagram of a mobile communication terminal apparatus according to the first embodiment. As shown in FIG. 1, the mobile communication terminal apparatus according to the present embodiment includes an input control unit 1, a position information acquisition unit 2, a condition storage unit 3, a power control unit 4, a WiFi control unit 5, a Bluetooth control unit 6, and 3GNW. (3rd Generation Network) It has the control part 7, the display control part 8, and the electric power supply part 9.

  The power supply unit 9 is a power source such as a rechargeable battery. The power supply unit 9 supplies power to the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8.

  The WiFi control unit 5 performs wireless communication using WiFi using the power supplied from the power supply unit 9. The WiFi control unit 5 can suppress power consumption unless the operation is started. Here, the start of the operation means that the WiFi control unit 5 activates the function in response to a function ON instruction from the power control unit 4 described later.

  The Bluetooth control unit 6 uses the power supplied from the power supply unit 9 to perform near field communication using Bluetooth. The Bluetooth control unit 6 can suppress power consumption unless the operation is started. Here, the start of the operation means that the Bluetooth control unit 6 activates the function in response to a function ON instruction from the power control unit 4 described later.

  The 3GNW control unit 7 uses the power supplied from the power supply unit 9 to perform wireless communication using a 3G line. The 3GNW control unit 7 can suppress power consumption unless the operation starts. Here, the start of the operation means that the 3GNW control unit 7 activates the function in response to an instruction to turn on the function from the power control unit 4 described later.

  The display control unit 8 uses the power supplied from the power supply unit 9 to display an image on a display unit such as a liquid crystal screen. The display control unit 8 can suppress power consumption unless the operation starts. Here, the start of the operation means that the display control unit 8 activates the function in response to an instruction to turn on the function from the power control unit 4 described later.

  The WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 are examples of the “power consumption unit”. Hereinafter, the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 may be referred to as “control objects” when they are not distinguished from each other. In the present embodiment, “WiFi control unit 5, Bluetooth control unit 6, 3GNW control unit 7 and display control unit 8” are cited as an example of the power consuming unit. As long as it has other functions, it may be a “power consuming unit”.

  The input control unit 1 receives an operation instruction input by an operator using a keypad or the like. For example, the input control unit 1 receives an ON / OFF instruction for the function of each unit input by the operator. Here, the ON / OFF instruction of the function of each unit is, for example, turning on or off any of the functions to be controlled among the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 and the display control unit 8 in FIG. This is an instruction to turn it off. Then, the input control unit 1 outputs an operation instruction such as an ON / OFF instruction for the received function to be controlled to the power control unit 4.

  The position information acquisition unit 2 has a GPS (Global Positioning System) in this embodiment. The position information acquisition unit 2 acquires the position information of the own device using the GPS that the position information acquisition unit 2 has. In the present embodiment, the position information acquisition unit 2 acquires latitude / longitude information as position information. Then, the position information acquisition unit 2 outputs the acquired position information to the power control unit 4. Here, in the present embodiment, the position information acquisition unit 2 acquires latitude / longitude information as position information. However, this may be other information as long as the position can be specified. For example, the position information is acquired based on communication by WiFi. You may do it.

  The condition storage unit 3 is a storage device such as a memory or a hard disk.

  The power control unit 4 always receives position information of its own device from the position information acquisition unit 2. Further, the power control unit 4 receives from the input control unit 1 an ON / OFF instruction for the function to be controlled, which is input by the operator.

  Then, the power control unit 4 turns on or off any of the functions of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 from the received ON / OFF instruction of the function to be controlled. Get information about what to do. ON / OFF of a function for a certain control target corresponds to operating or stopping the control unit. Here, all of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 and the display control unit 8 consume power, and when the operation is stopped, the power consumption is eliminated. In other words, the power usage state changes depending on the operation of each unit. Therefore, turning on or off the function of each unit corresponds to changing the power usage state. Therefore, a state in which the function in each unit is turned on and a state in which the function is turned off, in other words, a state in which the operation is stopped or a state in which the operation is performed are collectively expressed as a “power usage state”.

  Next, the power control unit 4 causes the condition storage unit 3 to store the information on the power usage state specified by the operator and the information on the control target corresponding to the position information received from the position information acquisition unit 2. Hereinafter, the correspondence between the position information and the power usage state may be referred to as “power control condition”. That is, the power control unit 4 stores the power control condition in the condition storage unit 3. The power control unit 4 stores the power control condition in the condition storage unit 3 every time the operator inputs ON / OFF of the function to be controlled. Here, when the operator inputs an ON / OFF instruction for the function of each unit at the same position, the power control unit 4 sets the new power usage state as the power usage state at that position and the condition storage unit 3 To store the old power control condition. In this way, the power control unit 4 stores the power usage states of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 and the display control unit 8 corresponding to each position in the condition storage unit 3 as power control conditions. Register.

  The power control unit 4 controls the specified control target to operate in response to an ON / OFF instruction for the function of each unit from the operator. For example, when the power control unit 4 receives an instruction to turn on the function of the WiFi control unit 5, the power control unit 4 starts the operation of the WiFi control unit 5. For example, when an instruction to turn off the function of the 3GNW control unit 7 is received, the power control unit 4 stops the operation of the 3GNW control unit 7.

  The power control unit 4 has a timer. When the power control unit 4 does not receive an operation instruction input to each unit from the input control unit 1 for a predetermined time, the WiFi control unit 5 and the Bluetooth control unit 6 are set to enter the power saving mode. 3GNW control unit 7 and display control unit 8 are controlled. Here, the power saving mode is a mode in which the power consumption is reduced by lowering the operation of various functions of the device itself. The decrease in the operation of various functions includes, for example, stoppage of display on the liquid crystal screen by the display control unit 8. Other examples of the decrease in the operation of various functions include intermittently detecting the connection destination by the WiFi control unit 5, the Bluetooth control unit 6 and the 3GNW control unit 7, and reducing the communication speed. . The state in the power saving mode may be referred to as a “sleep state”.

  Furthermore, when the power control unit 4 receives an operation instruction input from the operator from the input control unit 1 while the device is operating in the power saving mode, the WiFi control unit 5, the Bluetooth control unit 6, The 3GNW control unit 7 and the display control unit 8 are controlled to operate in the normal mode. Here, the normal mode is a state in which the operation of each unit in the power saving mode is canceled and the operation is canceled. For example, the display control unit 8 displays a standby screen on the display unit, continuously detects the connection destination by the WiFi control unit 5, the Bluetooth control unit 6 and the 3GNW control unit 7, or returns the communication speed. Etc. Hereinafter, the change from the power saving mode to the normal mode may be referred to as “return from the sleep state”.

  Then, the power control unit 4 searches the condition storage unit 3 at the position received from the position information acquisition unit 2 at the timing of returning from the sleep state. Then, the power control unit 4 determines whether or not the power control condition corresponding to the position returned from the sleep state is stored in the condition storage unit 3. Here, in this embodiment, the power control unit 4 sets a predetermined range as a threshold value in consideration of the reach of a wireless signal such as WiFi and the accuracy of a GPS position information acquisition function as actual position information. As a result, the inside of the threshold is determined as the same position around the acquired latitude / longitude information. In this embodiment, for example, it is assumed that this certain range is 50 m.

  When the power control condition at the position returned from the sleep state is stored in the condition storage unit 3, the power control unit 4 acquires the information on the power usage state at the position returned from the sleep state and the information on the control target. And the electric power control part 4 performs control with respect to a control object so that it may be in the acquired electric power usage state. In other words, the power control unit 4 restores the power usage state of the control target at that position. For example, when the power control unit 4 acquires ON information on the function of the WiFi control unit 5 as information at the position returned from the sleep state, the power control unit 4 controls the WiFi control unit 5 to start an operation. On the other hand, when the information indicating that the function of the WiFi control unit 5 is OFF is acquired as the information at the position returned from the sleep state, the WiFi control unit 5 is controlled to stop the operation.

  Here, in the present embodiment, the restoration of the power usage state is performed with the return from the sleep state as a trigger, but other timing may be used for this trigger. For example, power-on of the mobile communication terminal device may be used as a trigger, or a repetition cycle may be determined in advance, and the power usage state may be restored every cycle. On the other hand, when the position information is always acquired and the power state is restored, the power consumption correspondingly increases, and there is a risk that the power consumption may be applied. In this regard, as in the present embodiment, power consumption can be suppressed by performing acquisition of position information and restoration of the power state in response to a predetermined trigger.

  In the present embodiment, the restoration of the power usage state has been described by taking the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 and the display control unit 8 as an example. If it has, there will be no restriction | limiting in particular in setting it as the restoration | recovery object of an electric power usage state.

  Next, with reference to FIG. 2, the flow of the power control condition registration process in the mobile communication terminal according to the present embodiment will be described. FIG. 2 is a flowchart of a power control condition registration process in the mobile communication terminal apparatus according to the first embodiment.

  The operator inputs an instruction to turn on or off any of the functions of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 and the display control unit 8 using a keypad or the like (step S101). The input control unit 1 outputs ON / OFF information of the function input by the operator and information on the control target to the power control unit 4.

  The power control unit 4 acquires the position information of the point that has received the function ON / OFF instruction from the operator from the position information acquisition unit 2 (step S102).

  Then, the power control unit 4 associates the power usage state information and the function ON / OFF target information with the condition storage unit 3 in correspondence with the position information of the point at which the function ON / OFF instruction is received from the operator. And the power control condition is registered (step S103).

  Then, the power control unit 4 controls the designated control target to operate in accordance with an ON / OFF instruction for the function of each unit from the operator (step S104).

  Next, with reference to FIG. 3, the flow of processing for restoring the power usage state in the mobile communication terminal apparatus according to the present embodiment will be described. FIG. 3 is a flowchart of the process of restoring the power usage state in the mobile communication terminal apparatus according to the first embodiment. The flow in FIG. 3 starts from a state in which the mobile communication terminal device is operating in the power saving mode.

  The power control unit 4 receives an operation instruction input from the operator from the input control unit 1. Thereafter, the power control unit 4 switches the operation of each unit to the normal mode, and returns the own device from the sleep state (step S201).

  And the electric power control part 4 acquires the positional information on the point which returned from the sleep state from the positional information acquisition part 2 (step S202).

  The power control unit 4 determines whether or not the position information that matches the position information of the point returned from the sleep state is in the power control condition stored in the condition storage unit 3 (step S203). If there is a matching power control condition (Yes at Step S203), the power control unit 4 controls the control target so that the power use state corresponding to the position returned from the sleep state stored in the condition storage unit 3 is obtained. (Step S204).

  On the other hand, when there is no matching position information (No at Step S203), the power control unit 4 ends the operation without restoring the power usage state. Thereafter, the power control unit 4 waits until a return from the sleep state occurs, and executes the process of the flowchart of FIG. 3 when the return from the sleep state occurs.

  As described above, the mobile communication terminal apparatus according to the present embodiment automatically stores the position where the function of each unit is turned ON / OFF, and the mobile communication terminal apparatus is in the stored position. Then, each unit is operated so that the stored power usage state is obtained. Therefore, since the position where the function of each part is turned ON / OFF is automatically stored, the power control condition is automatically registered without the explicit power control registration by the user, and the power control is automatically performed. Learning can be realized and the labor of the operator can be reduced. Furthermore, by operating each unit so that the stored power usage state is stored at the stored position, it is possible to suppress the operation of functions that are considered unnecessary for the operator, and to efficiently reduce power consumption. Can do.

  In addition, since the power control condition is automatically registered, it is possible to prevent forgetting to register and to cover the actual usage place. Moreover, since the power control condition is registered based on the actual usage situation, it is possible to perform appropriate power control corresponding to the actual usage.

  FIG. 4 is a block diagram of the mobile communication terminal apparatus according to the second and third embodiments. As shown in FIG. 4, the mobile communication terminal apparatus according to the present embodiment is obtained by further adding an operation monitoring unit 10 to the mobile communication terminal apparatus according to the first embodiment.

  The input control unit 1, the position information acquisition unit 2, the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, the display control unit 8, and the power supply unit 9 have the same functions as the units in the first embodiment. Since there is, description is abbreviate | omitted here.

  The power control unit 4 receives an operation instruction input from the input control unit 1. Then, the power control unit 4 controls the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 according to the received operation instruction. This operation instruction includes, for example, ON / OFF of the function of each unit, an execution instruction for processing for each unit, and the like. For example, when receiving ON / OFF input of the function of each unit, the power control unit 4 activates the corresponding function.

  The power control unit 4 stores a predetermined period as a threshold for operation control. And the electric power control part 4 receives the operation information of the WiFi control part 5, the Bluetooth control part 6, the 3GNW control part 7, or the display control part 8 from the operation | movement monitoring part 10 mentioned later. Here, the operation information is, for example, process execution information in the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, or the display control unit 8. For example, when the WiFi control unit 5 performs wireless communication by WiFi, the power control unit 4 receives operation information indicating that the WiFi control unit 5 has executed processing from the operation monitoring unit 10. That is, the power control unit 4 can determine whether or not each unit has been used by receiving the operation information. Then, the power control unit 4 uses the operation information received from the operation monitoring unit 10 to measure the duration of each unused state of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8. To do. If the duration of any unused state of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 or the display control unit 8 exceeds a threshold value, the power control unit 4 The OFF of the control target function whose duration exceeds the threshold is determined.

  Further, the power control unit 4 acquires the position information of the point where the function is determined to be OFF from the position information acquisition unit 2.

  Then, the power control unit 4 causes the condition storage unit 3 to store the information on the power usage state corresponding to the function OFF and the control target of the function OFF in correspondence with the position information of the point where the function OFF is determined. Furthermore, the power control unit 4 performs control so as to stop the operation of the control target determined to turn off the function among the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, or the display control unit 8.

  Further, as in the first embodiment, the power control unit 4 performs control so as to enter the power saving mode in accordance with the operation state of each unit. Further, the power control unit 4 receives an operation instruction input from the operator and performs control to switch from the power saving mode to the normal mode.

  When the power control unit 4 returns from the sleep state, the power control unit 4 searches the condition storage unit 3 at the position received from the position information acquisition unit 2, and the power control condition that matches the position information of the point returned from the sleep state. It is determined whether or not it is stored in the condition storage unit 3. When the power control condition corresponding to the position information of the point returned from the sleep state is stored in the condition storage unit 3, the power control unit 4 includes the information on the power use state at the position returned from the sleep state and the control thereof. Get the target. And the electric power control part 4 controls with respect to a control object so that it may be in the acquired electric power usage state. For example, when the power control unit 4 acquires OFF of the WiFi control unit 5 as information on the power usage state at the position returned from the sleep state, the power control unit 4 controls to stop the operation of the WiFi control unit 5.

  The operation monitoring unit 10 determines whether each unit of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 has executed the respective processes. For example, the operation monitoring unit 10 may monitor the actual operation of each unit and determine that the monitoring target has executed the process when a predetermined process is executed on the monitoring target. Further, for example, the operation monitoring unit 10 may determine that the process has been executed when a process execution command from the operator is input to each unit.

  Then, the operation monitoring unit 10 notifies the power control unit 4 of operation information of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8. For example, when there is a control target that has executed the process among the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8, the operation monitoring unit 10 uses the information on the control target that has executed the process as power. Notify the control unit 4.

  Next, with reference to FIG. 5, the flow of the registration process of the power control condition of the mobile communication terminal according to the present embodiment will be described. FIG. 5 is a flowchart of the power control condition registration process of the mobile communication terminal apparatus according to the second embodiment.

  The operation monitoring unit 10 monitors the operation of each unit in the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 (step S301). Then, the operation monitoring unit 10 notifies the power control unit 4 that the monitoring target has performed processing.

  The power control unit 4 determines whether any of the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7 and the display control unit 8 has a non-use duration exceeding a threshold (step S302). When the power control unit 4 determines that there is no unused duration exceeding the threshold (No at Step S302), the process returns to Step S301.

  On the other hand, when there is a case where the non-use duration exceeds the threshold (Yes in step S302), the power control unit 4 determines OFF of the function to be controlled whose non-use duration exceeds the threshold. (Step S303).

  And the electric power control part 4 acquires the positional information on the point which determined OFF of the function from the positional information acquisition part 2 (step S304).

  Next, the power control unit 4 stores the information on the target of function OFF and the power usage state corresponding to the function OFF in the condition storage unit 3 in correspondence with the position information of the point where the function OFF is determined. A control condition is registered (step S305).

  Then, the control target that has received the function OFF control from the power control unit 4 performs the function OFF and stops the operation (step S306).

  Further, the flow of control of each unit by the power control unit 4 using the power control condition in the present embodiment is the same as the flow described with reference to FIG.

  As described above, the mobile communication terminal apparatus according to the present embodiment determines that the function is turned off when the function is on and the unused state continues for a predetermined period of time, and the position and Register the power usage status. Then, the mobile communication terminal apparatus according to the present embodiment controls the registered power usage state at the registered position. The fact that a function is not used for a certain period of time in a certain place can be considered as a place where the function is not used or cannot be used. Therefore, the mobile communication terminal device according to the present embodiment can automatically register a place where a specific function is not used or cannot be used, and further, by turning off a function not used in that place, wasteful power consumption is achieved. Can be reduced.

(Modification)
Next, a modification of the mobile communication terminal device according to the second embodiment will be described. In the second embodiment, the function OFF is determined when the duration of non-use of any of the control targets exceeds a threshold value. On the other hand, in this modification, the function is turned off when the duration of one non-use exceeds the threshold value in a state where both of two control targets having functions that can be substituted for each other are operating. This is different from the second embodiment. Therefore, in the following, the operation for determining the function OFF will be mainly described.

  For example, wireless communication using WiFi by the WiFi control unit 5 and communication using a 3G line by the 3GNW control unit 7 can be substituted. Therefore, in the following, the WiFi control unit 5 and the 3GNW control unit 7 will be described as an example as two control targets having mutually replaceable functions.

  When the power control unit 4 receives a function ON command for the WiFi control unit 5 or the 3GNW control unit 7 from the input control unit 1 and controls to turn on the function, the control target with the function turned on operates. It is determined that In addition, when the power control unit 4 receives a function OFF command for the WiFi control unit 5 or the 3GNW control unit 7 from the input control unit 1 and controls to turn off the function, the control target with the function turned on operates. Judge that it is not. Using these determinations, the power control unit 4 determines whether or not both the WiFi control unit 5 and the 3GNW control unit 7 are operating.

  Further, the power control unit 4 receives the operation information of the WiFi control unit 5 and the 3GNW control unit 7 from the operation monitoring unit 10.

  Then, the power control unit 4 determines whether or not any one of the non-use durations exceeds the threshold in a state where both the WiFi control unit 5 and the 3GNW control unit 7 are operating. When either one of the non-use durations exceeds the threshold, for example, when 10 minutes is used as the threshold, the functions of both the WiFi control unit 5 and the 3GNW control unit 7 are turned on even though the function is ON. This is the case where communication is performed for 10 minutes.

  When any one of the non-use durations exceeds the threshold, the power control unit 4 determines to turn off the function on the side that is not used. For example, when the functions of both the WiFi control unit 5 and the 3GNW control unit 7 are ON as described above, and communication is performed for 10 minutes using only the 3G line, the power control unit 4 performs the WiFi control. The function of the unit 5 is turned off.

  Furthermore, the power control unit 4 acquires position information from the position information acquisition unit 2 when the function OFF is determined.

  Then, the power control unit 4 causes the condition storage unit 3 to store the power usage state corresponding to the function OFF and the information on the control target of the function OFF in correspondence with the position information of the point where the function OFF is determined. Register control conditions. Furthermore, the power control unit 4 performs control so as to stop the operation of the WiFi control unit 5 or the 3GNW control unit 7 that determines the function OFF.

  Here, also in this modified example, the control by the power control unit 4 using the registered power control condition is the same as in the case of the second embodiment, and thus the description thereof is omitted.

  Next, with reference to FIG. 6, the flow of the registration process of the power control condition of the mobile communication terminal device according to this modification will be described. FIG. 6 is a flowchart of the power control condition registration process of the mobile communication terminal device according to the modification of the second embodiment.

  The operation monitoring unit 10 monitors the operation of each unit in the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, and the display control unit 8 (step S401). Then, the operation monitoring unit 10 notifies the power control unit 4 that the monitoring target has performed processing.

  The power control unit 4 determines whether or not the WiFi control unit 5 is operating, that is, whether or not the WiFi communication function is ON (step S402). When the power control unit 4 determines that the WiFi communication function is OFF (No in step S402), the process returns to step S401.

  On the other hand, when the WiFi communication function is ON (Yes at step S402), the power control unit 4 determines whether the 3GNW control unit 7 is operating, that is, whether the 3G communication function is ON. Is determined (step S403). When the power control unit 4 determines that the 3G communication function is OFF (No at Step S403), the process returns to Step S401.

  On the other hand, when the 3G communication function is ON (Yes in step S403), the power control unit 4 determines whether the duration of non-use of either the WiFi control unit 5 or the 3GNW control unit 7 has exceeded the threshold value. Determination is made (step S404). When the power control unit 4 determines that the duration of both non-uses does not exceed the threshold (No at Step S404), the process returns to Step S401.

  On the other hand, when any one of the non-use durations exceeds the threshold (Yes in step S404), the power control unit 4 turns off the function on the side where the non-use duration exceeds the threshold. Determination is made (step S405).

  And the electric power control part 4 acquires the positional information on the point which determined OFF of the function from the positional information acquisition part 2 (step S406).

  Next, the power control unit 4 stores the information on the target of function OFF and the power usage state corresponding to the function OFF in the condition storage unit 3 in correspondence with the position information of the point where the function OFF is determined. A control condition is registered (step S407).

  Then, the control target that has received the function OFF control from the power control unit 4 executes the own function OFF and stops the operation (step S408).

  As described above, the mobile communication terminal apparatus according to the modified example of the second embodiment is in a state in which one of the functions is not used for a predetermined period when two functions that can substitute for each other's functions are operating. If it continues, it decides to turn off the function, and registers its position and power usage state. When two functions that can substitute each other's functions are operating, even if one function is turned off, the other function can be substituted. Therefore, the function can be turned off more safely. Therefore, the mobile communication terminal apparatus according to this modification can turn off the function while ensuring safety, and can reduce wasteful power consumption.

  In addition, the functions described in the second embodiment and the modifications thereof can be used in combination with the functions of the first embodiment. When used in combination, finer power control can be performed.

  Next, a mobile communication terminal apparatus according to the third embodiment is described. The functional blocks of the mobile communication terminal device according to the present embodiment are also represented by the block diagram of FIG.

  Since the input control unit 1, the position information acquisition unit 2, the WiFi control unit 5, the Bluetooth control unit 6, the 3GNW control unit 7, the display control unit 8, and the power supply unit 9 have the same functions in the first embodiment. The description is omitted here.

  The operation monitoring unit 10 monitors the operation of the WiFi control unit 5, and notifies the power control unit 4 of access point detection information when the WiFi control unit 5 detects an access point that is a connection destination of WiFi communication.

  The operation monitoring unit 10 monitors the operation of the WiFi control unit 5 and detects the connection state of WiFi communication. Then, the operation monitoring unit 10 notifies the power control unit 4 of information on the detected connection state of WiFi communication.

  The power control unit 4 receives an access point detection notification from the operation monitoring unit 10 by the WiFi control unit 5. In addition, the power control unit 4 acquires the position information of the point that has received the notification of the access point detection from the position information acquisition unit 2. Then, the power control unit 4 causes the condition storage unit 3 to store the position information of the point that has received the notification of detection of the access point.

  When the power control unit 4 receives a function ON command for the WiFi control unit 5 or the 3GNW control unit 7 from the input control unit 1 and controls to turn on the function, the control target with the function turned on operates. It is determined that In addition, when the power control unit 4 receives a function OFF command for the WiFi control unit 5 or the 3GNW control unit 7 from the input control unit 1 and controls to turn off the function, the control target with the function turned on operates. Judge that it is not. Using these determinations, the power control unit 4 determines whether or not both the WiFi control unit 5 and the 3GNW control unit 7 are operating.

  In addition, the power control unit 4 receives information on the connection state of WiFi communication from the operation monitoring unit 10. Then, the power control unit 4 determines whether or not the WiFi communication has changed from the connected state to the disconnected state from the received information on the connection state of the WiFi communication.

  When both the WiFi control unit 5 and the 3GNW control unit 7 are operating, or when the WiFi communication changes from the connected state to the non-connected state, the power control unit 4 displays the position information of the point at that time as the position information acquisition unit Get from 2. Then, the power control unit 4 calculates the distance between the acquired position and the position of the access point stored in the condition storage unit 3. The power control unit 4 determines whether or not the calculated distance is within a predetermined distance.

  If the calculated distance is within the predetermined distance, the power control unit 4 turns off the function of the WiFi control unit 5. On the other hand, if the calculated distance is longer than the predetermined distance, the power control unit 4 keeps the function of the WiFi control unit 5 ON.

  Next, with reference to FIG. 7, the flow of processing for restoring the power usage state in the mobile communication terminal according to the present embodiment will be described. FIG. 7 is a flowchart of the process of restoring the power usage state in the mobile communication terminal apparatus according to the third embodiment.

  The operation monitoring unit 10 monitors the operation of the WiFi control unit 5 (step S501). Then, when the WiFi control unit 5 detects an access point that is a connection destination of WiFi communication, the operation monitoring unit 10 notifies the power control unit 4 of access point detection information.

  The power control unit 4 determines whether or not the WiFi control unit 5 is operating, that is, whether or not the WiFi communication function is ON (step S502). When the power control unit 4 determines that the WiFi communication function is OFF (No in step S502), the process returns to step S501.

  On the other hand, when the WiFi communication function is ON (Yes in step S502), the power control unit 4 determines whether the 3GNW control unit 7 is operating, that is, whether the 3G communication function is ON. Is determined (step S503). When the 3G communication function is OFF (No in step S503), the power control unit 4 determines whether the WiFi communication has shifted from the connected state to the disconnected state (step S504). When the power control unit 4 determines that the transition from the connection state of the WiFi communication to the non-connection state has not occurred (No at Step S504), the process returns to Step S501.

  When the 3G communication function is ON (step S503 affirmative) or the WiFi communication has shifted from the connected state to the non-connected state (step S504 affirmative), the power control unit 4 obtains the position information of the local point as the position information acquisition unit 2 (Step S505).

  The power control unit 4 calculates the distance between the position of the local point and the position of the access point. Then, the power control unit 4 determines whether or not the calculated distance is within a predetermined distance (step S506). When the power control unit 4 determines that the calculated distance is within a predetermined distance determined in advance (Yes at Step S506), the process returns to Step S501.

  On the other hand, when the calculated distance exceeds the predetermined distance determined in advance (No in step S506), the power control unit 4 turns off the function of the WiFi control unit 5 to perform the WiFi communication operation. Stop (step S507).

  As described above, the mobile communication terminal device according to the third embodiment is separated from the access point of the WiFi communication when the WiFi communication and the 3G communication are operating or when the WiFi communication is disconnected. If so, the WiFi communication function is turned off. When WiFi communication and 3G communication are operating, WiFi communication can be replaced by 3G communication. If the access point is outside the communication range of the WiFi communication, there is no point in operating the WiFi communication. Thus, by turning off the WiFi communication, it is possible to safely reduce wasteful power consumption. Further, when the WiFi communication is disconnected, it is useless to activate the WiFi communication if it is out of the communication range, but it may be disconnected in the radio wave state regardless of the communication range. Therefore, by turning off the WiFi communication only when it is out of the communication range, it is possible to reduce wasteful power consumption without hindering the WiFi communication.

  Here, functions such as WiFi are intermittently activated, and when the connection partner registered in advance is detected, the activation state is continued, and when the connection partner is lost, the intermittent activation state is established, thereby reducing power consumption. There are conventional techniques. However, in this prior art, even if the other party is temporarily lost due to the wireless state, it becomes an intermittent activation state, and it takes time to find the other party again. On the other hand, in the mobile communication terminal device according to the present embodiment, the WiFi communication is not turned off within the communication range, so even if the wireless state is bad and the communication is temporarily interrupted, the partner is not searched again. , Can reconnect quickly.

  Here, the functions described in the third embodiment can be used in combination with the functions of the first embodiment, the second embodiment, or the modification of the second embodiment. When used in combination, finer power control can be performed.

  Next, a mobile communication terminal apparatus according to Embodiment 4 will be described. The functional blocks of the mobile communication terminal apparatus according to the present embodiment are also represented by the block diagram of FIG. The mobile communication terminal apparatus according to the present embodiment is different from the first embodiment in that a position type based on ambient noise is used as position information. Thus, hereinafter, acquisition of position information and power control based on the acquired position information will be mainly described. In the following description, each part having the same reference numeral as in the first embodiment has the same function unless otherwise described.

  The position information acquisition unit 2 determines whether or not ambient noise at a certain point is in a silent state. Furthermore, when the ambient noise is not silent, the position information acquisition unit 2 acquires the voice intensity and volume fluctuation in a specific frequency band as the ambient noise at that point. The position information acquisition unit 2 notifies the power control unit 4 of information on ambient noise at a certain point.

  When the power control unit 4 receives an ON / OFF input of the function of each unit from the operator from the input control unit 1, the power control unit 4 obtains information on ambient noise at the point where the ON / OFF input is received from the position information acquisition unit 2. Receive. Then, the power control unit 4 determines the position type from the received ambient noise. For example, if it is a silence state, it will determine with it being a home. In addition, it is considered that there is a feature in the sound intensity of a specific frequency band if it is a place having characteristic environmental noise such as office equipment such as a PC. Therefore, when there is a characteristic in the sound intensity of the specific frequency band, it is determined as the office. Furthermore, if it is a running sound of a train etc., it is thought that there is a characteristic in the volume fluctuation of a specific frequency band. Therefore, if there is a characteristic in volume fluctuation in a specific frequency band, it is determined that the train is in the train.

  Then, the power control unit 4 stores the information on the control target of the function ON / OFF and the power usage state in the condition storage unit 3 in correspondence with the position type at the point where the ON / OFF input is received. Register control conditions.

  Then, the power control unit 4 acquires the ambient noise information from the position information acquisition unit 2 at the timing of returning from the sleep state. Furthermore, the power control unit 4 determines the current position type from the acquired ambient noise. Then, the power control unit 4 determines whether or not information on a position type that matches the current position type is registered in the condition storage unit 3. When information that matches the information on the current position type is registered, the power control unit 4 controls the control target that is registered so as to be in the corresponding power usage state.

  For example, when at home, the communication function should be operated in accordance with the home network environment. Therefore, if ON / OFF of the function is registered according to the ambient noise at home, only the function according to the home network environment can be operated at home, and wasteful power consumption can be reduced. Also, it is conceivable to turn off all communication functions on the train. Therefore, if the function ON / OFF is registered according to the ambient noise of the train, the communication function can be appropriately turned off, and wasteful power consumption can be reduced.

  As described above, the mobile communication terminal apparatus according to the present embodiment determines the position type using the ambient noise, and performs control so that the same operation is performed at the location of the same position type. Thereby, even if it is in the state where the communication apparatus for acquiring positional information, such as GPS, cannot be used, appropriate electric power control according to the position can be performed.

  Here, the functions described in the fourth embodiment can be used in combination with the functions of the first embodiment, the second embodiment, the modification of the second embodiment, or the third embodiment. When used in combination, power control can be performed even when position information cannot be acquired, and wasteful power consumption can be reduced more appropriately.
