Description

  The present invention relates to a portable device and a usable time display method thereof, and more particularly to a portable device capable of displaying a callable time and a usable time display method thereof.

  Conventionally, since the remaining battery level of a mobile phone is displayed as a battery pictogram (pictograph), the accurate callable time cannot be grasped, and the mobile phone may be suddenly disconnected during the call.

  Further, a mobile phone that displays the available call time more accurately than the battery-pict type mobile phone with battery remaining amount display is disclosed in, for example, Patent Document 1.

  According to the mobile phone described in Patent Document 1 (see paragraphs 0017 to 0021), the remaining power value of the battery is calculated by the current measurement unit and the time measurement unit from the power value during full charge. A method of obtaining by subtracting the calculated power value is adopted. In addition, as a reference for the consumption current value, the consumption current value corresponding to the standby operation mode and the call operation mode is used, and for this consumption current value, the data is updated without accumulating the data. Yes.

JP-A-9-181804 (page 4, FIG. 1)

  The conventional mobile phone described above has a drawback in that it cannot prevent a sudden disconnection due to a shortage of batteries because it does not notify the available call time according to the state at the time of outgoing call.

  In addition, with the spread of videophones that consume a lot of battery power, it becomes more difficult to grasp the available call time. That is, since a notification prompting switching from a videophone to a voice call is not made a certain time before disconnection due to battery shortage, the user cannot be selected to change to a voice call. For this reason, there is a drawback that battery consumption cannot be suppressed and the callable time cannot be extended.

  The object of the present invention is to prevent sudden disconnection due to battery shortage, particularly disconnection during a call, and to notify a user to switch from a videophone call to a voice call, etc. for a certain time before disconnection due to battery shortage. It is an object of the present invention to provide a portable device that allows a user to select a change to a voice call and suppresses battery consumption and extends the callable time.

  The portable device of the present invention includes a wireless data monitoring unit that controls data transmitted and received via an antenna, a battery state monitoring unit that monitors a remaining battery level, a consumption current value table, transmission power and consumption current value Corresponding data is set, a memory connected to the wireless data monitoring unit and recording transmission power value history data, and monitoring information from the wireless data monitoring unit and the battery state monitoring unit, And an arithmetic processing unit that performs arithmetic processing using the table and the data, and displays the device usable time on the display unit during a call.

  The current consumption value stored in the memory can be set based on the type of transmission such as voice or videophone and the transmission power value corresponding to the reception sensitivity at the time of transmission.

  Further, the transmission power value corresponding to the type of transmission and the reception sensitivity at the time of transmission stored in the memory uses an average value of transmission power values during past calls, and when there is no past history, A predetermined value can be used.

  Further, the notification of the call or communication possible time can be made to the user at the time of outgoing call or before a predetermined time before disconnection due to battery shortage during the call.

  In addition, when the type of call is a videophone and a warning that the remaining battery power is low is received during the call, the videophone is disconnected according to the user's selection, and the same call or It is possible to make a voice call to a communication partner.

  The device usable time can be displayed only by displaying pictograms on the display unit during standby, and can be performed by combining time display and warning sound on the display unit during a call.

  The portable device usable time display method according to the present invention includes a type determination step of determining a type of transmission by a call type determination unit at the time of outgoing call, and a battery state monitoring unit that determines whether or not voice transmission has occurred in the type determination step. A first remaining amount confirming step for confirming the remaining amount, a disconnecting step for performing a disconnecting process when there is not enough battery remaining as a result of the confirmation in the first remaining amount confirming step, and a television in the type determining step. When it is determined that the call is originated, if there is not a sufficient remaining battery level as a result of the confirmation in the second remaining capacity confirmation step in which the remaining battery capacity is confirmed by the battery state monitoring unit and the second remaining capacity confirmation step. In the re-transmission determination step for determining whether to re-transmit from the arithmetic processing unit to the display unit, and in the re-transmission determination step, the user does not desire In the step of switching to the voice transmission and starting over from the beginning when re-calling is desired, and in the first and second remaining amount confirmation steps, a sufficient battery is provided for both voice and videophone calls. When there is a remaining amount, the battery remaining amount data is transferred from the battery state monitoring unit to the arithmetic processing unit, the reception sensitivity is measured by a wireless unit, and the reception sensitivity is confirmed. Transferring the value to the arithmetic processing unit, wherein the arithmetic processing unit reads a current consumption value corresponding to each type of transmission from the current consumption value table of the memory, and calculates a callable time; And notifying the user of the calculated callable time from the display unit.

  In addition, the portable device usable time display method according to the present invention includes a current consumption value and battery remaining amount data corresponding to the reception sensitivity transmitted at regular intervals from the wireless data monitoring unit and the battery state monitoring unit during a call. Based on the type determination step of calculating the callable time in the arithmetic processing unit and determining the type of call when the remaining callable time set in advance by the user matches the calculated callable time; When it is determined as a voice call in the determination step, a warning sound is sounded for a certain period of time, a warning sound notification step for notifying the user that the remaining battery level is low, and a videophone call is determined in the type determination step When the reconnection determination step determines whether or not to reconnect by voice call on the display unit, and the reconnection determination step, the user does not wish to reconnect The videophone call is continued, while the user wishes to reconnect, the videophone call is temporarily disconnected and automatically sent to the same party by voice call. .

  Since the portable device and the usable time display method of the present invention are difficult to grasp the call or communication possible time of a mobile phone or the like only with battery pictograms, the mobile device user is notified by notifying the available call time when making a call. It is possible to inform the user of the available call time and to prevent sudden disconnection.

  In the present invention, since the transmission power value corresponding to the current consumption value is different between the time of outgoing call and the time of calling, the current consumption value used for calculating the callable time is set as the type of outgoing call (voice transmission / TV Since the transmission power value corresponding to the telephone transmission and the like and the reception sensitivity is set, there is an effect that an accurate usable time can be displayed.

  Further, in the present invention, since the average transmission power value at the time of the past call is used as the transmission power value corresponding to the type of transmission (voice transmission, videophone transmission, etc.) and the reception sensitivity at the time of transmission, the cellular phone The longer it is used, the more it can be set to the transmission power value suitable for the terminal, and there is an effect that the accuracy of the call (communication) possible time can be further improved.

  The portable device of the present invention includes a battery state monitoring unit, a wireless data monitoring unit, a memory and an arithmetic processing unit, and a display unit. The current consumption value corresponding to the transmission power value during a call and the battery state monitoring during transmission The callable time is calculated by the arithmetic processing unit from the remaining battery level measured by the unit and displayed on the display unit, thereby notifying the user of the callable time with high accuracy. Since the current consumption corresponding to this transmission power value is different between outgoing and incoming calls, the type of outgoing call (voice outgoing / videophone outgoing) and the reception sensitivity measured by the radio unit connected to the antenna when outgoing Set based on the corresponding transmission power value. The transmission power value corresponding to the type of transmission and the reception sensitivity at the time of transmission uses the average value of the transmission power values at the time of past calls stored in the memory. For this reason, the more the mobile phone is used, the more the transmission power value is suitable for the terminal itself, so that the accuracy of the callable time, which is the usable time, can be increased.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a main block diagram of a cellular phone showing an embodiment of the present invention. As shown in FIG. 1, the mobile phone of this embodiment includes an antenna 11 that transmits and receives radio waves, a radio unit 12 that is connected to the antenna 11 and performs radio control and measurement of transmission power and reception sensitivity, and operation of the terminal A control unit 13 for controlling the battery, a display unit 14 for displaying battery pictograms and callable time, a memory 15 for storing transmission power data and the like, and a battery 16. The control unit 13 monitors transmission / reception of information to / from the wireless unit 12, and transmits a transmission power data and current consumption value data to / from the memory 15, a display unit 14, A battery state monitoring unit 13b that is connected to the battery 16 and monitors the battery state, and is connected to both the monitoring units 13a and 13b, the display unit 14, and the memory 15, and calculates a callable time, an average value of transmission power, and the like. And a call type determination unit 13d that determines a call type such as a voice call or a videophone call by inputting an operation key. It should be noted that components such as operation keys (buttons) that are not directly related to the invention are omitted here.

  Next, a method for calculating the callable time as the usable time of the mobile phone will be described with reference to FIGS.

  FIG. 2 is a diagram showing an example of the memory in FIG. As shown in FIG. 2, the memory 15 is obtained by a consumption current value table 21 in which a correspondence expression between reception sensitivity and transmission power and consumption current for each type of transmission (voice, TV mode) is set, and the corresponding expression. The transmission power and consumption current value data 22 and the transmission power value history data 23 recorded for averaging are recorded. Here, although the correspondence formula of the consumption current value table 21 is fixed, the transmission power obtained from this correspondence formula and the consumption current value data 22 and the transmission power value history data 23 for averaging are written and It can be erased.

  For example, the transmission power value history data 23 is obtained by sorting the transmission power value data calculated by the calculation processing unit 13c according to the type of transmission (voice, TV) and reception sensitivity (αβγ...). As a result, the accuracy of the transmission output value estimated from the reception sensitivity at the time of transmission can be increased by measuring the transmission output value during a call and taking the average value with the past data.

  FIG. 3 is a calculation flow chart of the callable time in FIG. As shown in FIG. 3, when the call type determination unit 13d of the control unit 13 determines that the voice is transmitted when the call is first made (step 301: hereinafter abbreviated as S301, the same applies to others), the battery state monitoring unit 13b. In step S302, the remaining battery level is checked (S302). That is, the transmission is stopped.

  Next, when it is determined that a videophone call is made in the above-described outgoing call type determination step S301), the battery remaining amount is similarly checked by the battery state monitoring unit 13b in the remaining battery amount checking step S304. If there is not enough battery remaining in this battery remaining amount confirmation step S304, the arithmetic processing unit 13c causes the display unit 14 to display “There is not enough remaining battery power. Do you want to switch to voice again?”. (S305). Here, when the user selects No, a disconnection process is performed (S307), and when Yes is selected, switching to voice transmission is performed (S306), and the process is restarted from the start.

  Further, in the above-described steps 302 and 304, when there is a sufficient remaining battery level for both voice and videophone calls, the remaining battery level data is transferred from the battery state monitoring unit 13b to the arithmetic processing unit 13c. Next, the reception sensitivity is measured by the wireless unit 12 (S308).

  Thereafter, after the reception sensitivity measured by the wireless unit 12 is confirmed by the wireless data monitoring unit 13a, the value of the reception sensitivity is transferred to the arithmetic processing unit 13c. Here, the arithmetic processing unit 13c acquires the remaining battery level and the reception sensitivity information, and reads the current consumption value corresponding to each reception sensitivity and each type of transmission from the current consumption value table 21 in the memory 15 to obtain data. Acquisition is performed (S309). As a result, the arithmetic processing unit 13c calculates a callable time from the read current consumption value and the remaining battery level (S310), and notifies the user of the callable time from the display unit 14 (S311).

  Next, an update procedure for the consumption current value table 21 of the memory 15 will be described with reference to FIGS. 4 and 5.

  FIG. 4 is a diagram for explaining the correspondence between the transmission conditions of the memory and the current consumption in FIG. As shown in FIG. 4, the consumption current value table 21 of the memory 15 describes the transmission power value and the consumption current value for each reception sensitivity (αβγ...) And for each call type (voice, TV). Is. In this current consumption value table 21, γA-P to αA-P and γTP-P to αTP are filled with respective transmission output average values, and γA-C to αA-C and γT-C to αT. In -C, a current consumption value corresponding to each transmission output average value is entered. In the above-described formula, A is a voice call, T is a video call, P is a transmission power value, and C is a symbol representing a current consumption value, which can be expressed simply as a numerical value. That is, the value read from the transmission power / current consumption value correspondence data 22 can be entered. Here, for example, γA-P represents a transmission power value at the time of reception sensitivity γ in a voice call. The same applies hereinafter.

  More specifically, the current consumption value read from the transmission power / current consumption value correspondence data 22 is entered in the current consumption value table 21. This correspondence data 22 is fixed. For this reason, the average value (P1) of several transmission powers respectively stored in the voice / reception sensitivity of the transmission power value history data area 23, and the transmission power value (P2) with respect to the reception sensitivity of the current consumption value table 21 If there is a difference, the current consumption value for the average value P1 is read from the transmission power / current consumption value correspondence data 22, the transmission power value (changed from P2 to P1) and the transmission power / current consumption value in the current consumption value table 21 The consumption current value read from the correspondence data 22 is updated to the consumption current value table 21.

  FIG. 5 is a flowchart showing the operation for updating the current consumption value in FIG. As shown in FIG. 5, in the operation of updating the consumption current value for the memory 15, the transmission power is measured by the wireless unit 12 during a call (S501), after the end of the call (S502), and the transmission power value history in the memory 15 The transmission power data is stored in the corresponding item of the data 23 (S503). The data area of the history data 23 is classified according to the type of call and the value of reception sensitivity, and can store only a certain number of history data respectively. Therefore, when there is no space in the data area, the oldest data is erased and new data is stored.

  Next, after storing the data, all the history data of the item updated by the arithmetic processing unit 13c is read, and the average transmission power value is recalculated (S504). Thereafter, the current consumption value corresponding to the recalculated transmission power value is read from the transmission power / current consumption value correspondence data 22 in the memory 15 (S505), and it is determined whether or not there is a change in the current consumption value table 21. (S506). That is, in this step S506, if there is no change between the corresponding items (αA-C to γA-C, αT-C to γT-C) in the consumption current value table 21, the process ends without performing the update process. If there is a difference, the transmission power value and the current consumption value in the current consumption value table 21 are updated, and the process ends (S507).

  As described above, in the first embodiment, the notification in the sequence for calculating the callable time has been described in the pattern of notifying once during the call. However, the notification is displayed at the time of outgoing call by the program sequence using the CPU and the memory (not shown). Or can be displayed intermittently several times during a call, or a user can be notified a certain time before disconnection due to battery shortage during a call or during a call.

  Further, when the current consumption value stored in the memory 15 is set based on the type of transmission such as voice or videophone and the transmission power value corresponding to the reception sensitivity at the time of transmission, the transmission power during the past call is set. Use the average value. However, when there is no past history, a predetermined value is used.

  Furthermore, the notification of the callable time in the present embodiment is made to the user at the time of outgoing call or a predetermined time before disconnection due to battery shortage during the call.

  In addition, as described above, in this embodiment, when the type of outgoing call is selected as a video phone and a warning that the remaining battery level is low is received during the call, the video phone is disconnected according to the user's selection. Thus, it is possible to automatically make a voice call to the same call or communication partner.

  In short, the display of the device usable time in the present embodiment is only a pictogram display on the display unit 14 in order to prevent battery consumption during standby, and a flashing time display on the display unit 14 and an alarm by voice during outgoing calls and calls. By performing the display in combination, it is possible to realize an accurate display of usable time.

  FIG. 6 is a flowchart of a disconnection warning due to battery shortage for explaining another embodiment of the present invention. As shown in FIG. 6, this embodiment also notifies the available call time calculated from the remaining battery level and the current consumption value according to the situation at the time of transmission. This is an example in which a warning is given to the user before a certain time.

  First, during a call, the arithmetic processing unit 13c calculates a callable time from data of reception sensitivity and remaining battery level that are transmitted by the wireless data monitoring unit 13a and the battery state monitoring unit 13b at regular intervals. As a result, when the available call remaining time “X minutes” set by the user matches the calculated available call time (S601), the type of call is determined (S602).

  Here, in the case of a voice call, a warning sound is sounded for a certain period of time to notify the user that the remaining battery level is low (S603). Note that the available call time is not calculated after the notification.

  On the other hand, when it is determined to be a videophone call in the determination step S602, the display unit 14 notifies the user by displaying “The battery level is low and will you reconnect by voice call?” (S604). If the user selects No, the videophone call is continued. (S605). In this case, the callable time after the warning is displayed is not calculated.

  If the user selects Yes, the videophone is temporarily disconnected and automatically sent to the same party by voice call (S606). At this time, the available call time by voice call is calculated at the time of outgoing call and displayed on the display unit 14.

  In the case of the present embodiment, unless the user selects No, by calculating and displaying the available call time, there is no sudden disconnection of the call, and the accurate usage time can be grasped, thereby realizing improvement of the service. Can do.

  The present invention can be applied to any portable device such as a notebook computer using a battery as a power source in addition to the cellular phone.
