The present invention proposes various schemes for implementing a reservation event based power saving mode (hereinafter referred to as a reserved event power saving mode).

1. Scheduled event-based power saving mode

Generally, the reservation event setting is set to execute a specific reservation event (alarm, wake-up call, schedule, reservation call (transmission / reception), reservation message, reservation recording, reservation download, screen replacement, etc.) . The power saving mode is a mode for restricting the use of an item that consumes battery power for charging the battery (hereinafter referred to as a battery item).

Therefore, in the present invention, the power saving mode based reservation event based on the reservation event is performed by replacing the reserved event with an alternative means for performing the set reservation event, An activation mode, a reserved event control mode for setting a delay or an off for a reserved event, a power reserve control mode for reserving power off / on, and a power saving screen mode for only a part of the screen.

2. Setting the Alternative Means Activation Mode

In the present invention, when the battery remaining amount of the mobile terminal is larger than the remaining battery amount necessary for execution of a predetermined reservation event or when the remaining battery amount is smaller (or less) than the remaining battery amount necessary for execution of a predetermined reservation event All are configurable.

The former is a method of manually setting the user, and the latter is a method of causing the control unit of the mobile terminal to calculate the remaining amount of the battery and automatically display the UI related to the setting of the reserved event power saving mode so as to confirm the user. That is, in the present invention, the meaning of automatic and manual indicates whether a screen for setting the reserved event power saving mode is displayed by user selection or automatically by the control unit 180.

2.1 Setting the Alternative Means of Activation Mode (Manual)

FIG. 3 illustrates activation of an alternative means as an example of a manual setting of a power saving mode based on a reservation event according to an embodiment of the present invention.

When a predetermined reservation event and a reservation time are set, the user can see an indicator bar at the top of the screen and judge whether the set reservation event can be normally operated at the reservation time. If it is determined that the battery remaining amount is currently sufficient but the reservation event can not be completely executed at the set reservation time, the user can set the replacement means by selecting the 'reserved event power saving mode' item in the cell phone setting menu.

When the reserved event sleep mode item is selected, the controller 180 enters the reserved event sleep mode and automatically activates the replacement means and displays a list of reserved events (alternative means is activated).

If the user touches the 'unspecified' portion of a specific event, for example, an alarm / morning call event, on the screen for the reserved event power saving mode, the controller 180 displays an animation indicating that the current replacement means is currently being searched, A home telephone, a TV, a digital photo frame, an audio player, and a PC) capable of executing the alarm / morning call at the time on behalf of the terminal.

When the user selects a specific alternative means (eg, home telephone) from the displayed alternative means, the home telephone is set as an alternative means for the alarm / morning call (reservation event), and the user selects the storage menu to store the set alternative means do.

Accordingly, when the time reaches the set time of the alarm / morning call, the controller 180 transmits the alarm / morning call setting value of the mobile terminal to the home phone through the wireless communication unit 110, / Allows the morning call operation to be executed.

2.2 Setting the Alternative Means Activation Mode (Automatic)

As shown in FIG. 4, when a reservation event is set in the mobile terminal, a battery amount (hereinafter referred to as a necessary battery amount) necessary for executing the reservation event is set to a standby battery And a reserve battery amount which is a battery amount necessary for processing the reservation event.

Required battery level = standby battery level + reserved battery level

Therefore, in order for a scheduled event to be executed normally, the amount of battery should be larger than the sum of the amount of standby battery and the amount of consuming battery, otherwise proper management of remaining capacity and an additional method are needed.

FIG. 5A is a flowchart showing a setting of a power saving mode based on a reservation event according to an embodiment of the present invention, and FIG. 5B shows a screen display (UI) during automatic setting.

5A, when a specific event is set by the user (S10), the controller 180 calculates a standby battery amount and a reserved battery amount based on the battery consumption amount of the battery-related item, (S11). At this time, the battery related items include 3G data, wireless data (Wi-Fi, BT, GPS, acceleration, vibration, proximity, illumination) and display (LCD, LED)

When the required battery amount is calculated, the controller 180 checks whether the current battery amount is smaller than the calculated required battery amount (S12). If the current battery amount is smaller than the calculated required battery amount, the control unit 180 automatically turns off the battery-related item, and then controls the display unit 151 to automatically replace the replacement unit (S14). At this time, the battery-related items can be turned off stepwise according to the usage time pattern or the number of occurrences of the event. On the other hand, if it is larger, the step (S22) is repeatedly performed.

The automatic activation of the substitute means means an alternative means to perform the reservation event instead of activating the substitute device and performing the corresponding reservation event. The substitute means includes all devices having a means for communicating with the mobile terminal and having means for sending and receiving a telephone, sending and receiving messages, and displaying means. For example, the alternative means may include a telephone (a family phone, a friend phone, a home phone), a TV, a DVD, an electronic frame, an audio player, and a PC.

That is, if the current battery amount is smaller than the calculated required battery amount, the control unit 180 enters the reserved event power saving mode and automatically activates the replacement means and displays the reservation event list (alternative means activation on).

If the user touches the 'unspecified' portion of a specific event, for example, an alarm / morning call event, on the screen for the reserved event power saving mode, the controller 180 displays an animation indicating that the current replacement means is currently being searched, A home telephone, a TV, a digital photo frame, an audio player, and a PC) capable of executing the alarm / morning call at the time on behalf of the terminal.

When the user selects a specific substitute means (eg, home phone) from the displayed substitute means, the home phone is set as an alternative means for the alarm / morning call (reservation event), and the user selects the save menu, (Step S15).

Accordingly, when the alarm / morning call is set, the controller 180 transmits the alarm / morning call setting value of the mobile terminal to the home phone through the wireless communication unit 110 and performs an alarm / morning call operation (S16).

The control unit 180 transmits an incoming event to the corresponding device through the base station server when the alternative means is set to the device for which the called function is supported for the 'scheduled call / message (reception)' in the reserved event list , And the base station server performs the call forwarding to the alternate device in the call / message received at the current terminal (secretary mode).

On the other hand, when the user sets a device for which a calling function is supported as a substitute for the 'reserved call / message (calling)' in the reserved event list, the controller 180 transmits a reservation call (eg, And transmits the reservation call to the corresponding device to perform the reservation transmission on the reservation time.

If the user sets a device for which a recording function is supported for the 'scheduled recording' as an alternative means, the control unit 180 transmits a scheduled recording event to the corresponding device, Recording is performed, and the recorded image is transmitted to the terminal at a later time.

In addition, when the user sets a device for which download function is supported for the 'scheduled download' as an alternative means in the scheduled event list, the control unit 180 transmits a scheduled download event to the corresponding device, And downloads the content downloaded to the terminal at a later time. At this time, the content download includes downloading of reservation contents such as TV / PC or automatic retrieval of Internet from PC.

Finally, when the user sets a device for which the display function is supported for the 'screen substitution' as an alternative means in the reservation event list, the control unit 180 turns off the display unit 151 with the N-screen, Perform substitution.

The present invention provides various power saving modes other than activating the alternative means after automatically turning off the battery related items when the current battery amount is smaller than the calculated required battery amount. The various power saving modes correspond to the automatic power saving mode based on the reservation event, and include a reservation event control (delay or off), a power reserve control (after turning on and off) mode, and a power saving screen mode switching.

3. Reserved event control mode

FIG. 6 is a flowchart showing the setting of the reserved event control mode according to the embodiment of the present invention, and is an example of a delayed or off scheduled event.

In Fig. 6, steps S20 to S23 are the same as steps S10 to S13 of Fig. That is, when the event is set, the controller 180 checks whether the current battery amount is smaller than the required battery amount, and automatically turns off the battery related item when the event is smaller.

The control unit 180 retrieves a preset event from the memory 160 and notifies the display unit 180 of the preset event and displays 'delay' and 'off' as selection items of the corresponding reservation event (S24).

The user recognizes that the current battery amount is smaller than the required battery amount based on the displayed event selection item and selects the reserved event delay or reserved event off. Accordingly, the controller 180 delays the reservation event after a predetermined time or turns off or deletes the reservation event according to the user's selection.

As another example, the present invention may allow the control unit 180 to directly display the edit screen of the corresponding reservation event instead of performing the notification of the corresponding reservation event after step S23, Delay or off.

3. Power reserve mode

FIG. 7A is a flowchart showing the setting of a power reserve mode according to an embodiment of the present invention, and FIG. 7B is an example of a power reserve message message notification message.

The power saving mode shown in FIGS. 7A and 7B is a mode in which when the remaining battery power is less than the remaining battery power required until the preset time of the predetermined reservation event, .

In Fig. 7A, steps S30 to S33 are the same as steps S10 to S13 of Fig. That is, when the event is set, the controller 180 checks whether the current battery amount is smaller than the required battery amount, and automatically turns off the battery related item when the event is smaller.

The controller 180 automatically turns off the battery related item and displays a message asking to turn on the power of the terminal after turning off the power of the terminal due to insufficient remaining capacity of the battery as shown in FIG. 7B (S34)

If the user sees the message and selects 'Yes', the controller 180 turns the power of the terminal off (only the minimum function is turned on), and then turns on the power after a predetermined time to execute the reservation event. Accordingly, the control unit 180 delays the reservation event after a predetermined time or turns off or deletes the reservation event according to the user's selection. At this time, the present invention can provide user setting according to power off / on (minimum function setting).

4. Power saving screen mode

FIG. 8A is a flowchart illustrating a setting of a power saving screen mode according to an embodiment of the present invention, and FIG. 8B is an example of a power saving screen.

The power saving mode shown in FIGS. 8A and 8B means that the power saving screen UI is operated by using only a part of the screen in consideration of the battery remaining amount, not the whole screen.

When a predetermined event is set (S40), the controller 180 calculates a required battery amount and checks whether the current battery amount is smaller than the required battery amount (S41, S42)

If the current battery amount is smaller than the required battery amount, the control unit 180 automatically turns off the battery-related item (S43), and automatically enters the power saving screen mode in which only a part of the current screen is displayed and the remaining part is turned off S44). FIG. 8B shows a power saving screen UI displayed in the power saving screen mode, and includes a menu for setting / canceling the power saving screen UI.

FIG. 8C is a list of notes that deviate from the remaining battery level.

As shown in FIG. 8C, when the current battery level is smaller than the required battery level, the controller 180 may display a list of event lists to be performed after the current battery level is exceeded, that is, after the battery is turned off. The event list is displayed in the order of events that are periodically operated (e.g., alarms) and days of the week. FIG. 8C is an example in which when the user selects the wait event item in the remaining battery time menu, an event list that exceeds the current battery amount is displayed.

Therefore, after confirming the displayed event list, it is possible to set an alternative means or take a necessary means.

Thus, according to the present invention, when a reservation event is set, a replacement event is provided when the current battery capacity is smaller than the required battery capacity, or a variety of power saving modes are provided, so that the reservation event set by the user can not be executed Thereby improving the convenience of the user.
