JPH1188252A - Portable telephone set - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a portable telephone set that is independent of a reception environment and an operation interruption state and in which the power consumption is saved by user setting. SOLUTION: A monitor section 3 monitors whether key entry from an operation section 2 activates a battery saving function or inactivates the function. A control section 5 sets a time of a power-on timer and a power-off timer in a timer 4 according to a power-off time by key entry to start them and executes repetitively the activation of a power supply section 1 when the control section 5 receives an interruption by the power-off timer and the inactivation of the power supply section 1 when the control section 5 receives an interruption by the power-on timer while the battery saving function interrupts is effective.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system such as a mobile telephone system (cellular system) and an automobile telephone system, and more particularly to a mobile telephone employing a battery saving system.

[0002]

2. Description of the Related Art In a conventional mobile phone system (cellular system) or a mobile phone system adopting a battery saving system, in order to receive an incoming call at any time, the power is always turned on even if there is no incoming call. Therefore, a power saving operation such as so-called intermittent reception or automatic power-off when out of service area (for example, as described in Japanese Patent Application Laid-Open No. 4-355524, the input electric field during the reception operation has a required level). The receiving operation is stopped for a predetermined time when the lowering is continuously detected for a required time) or the power saving operation by stopping the display during the interruption of the operation (for example, as disclosed in Japanese Patent Application Laid-Open No. 6-291862). If no operation has been performed for a certain period of time, confirm that there is no problem in the telephone exchange operation and then turn off the display on the display). Receiving, or to achieve prolonged talk time was limited (the limit on the reduction of battery consumption).

[0003] The reason is that these conventional technologies basically assume that the power is always on as an operation thereof, and do not intentionally turn off the power by the user himself.
This is because it depends on the reception environment and the operation interruption status.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to prevent a battery from being exhausted due to the need to keep the power on at all times. It is an object of the present invention to provide a mobile phone capable of further saving power by enabling a user to arbitrarily set a time for turning off the power of the phone.

[0005]

Such a portable telephone has a battery saving selecting means for enabling or disabling a battery saving function by key operation, a power-on timer for turning on the power during a set time, and , A power-off timer for turning off the power only for the set time, and a power-on timer and a power-off timer according to a key-input power-off time, and activating them, and a power-off timer. A control unit that repeatedly executes the operation of turning off the power when the interruption of the power is turned on and turning on the power when the power-on timer is interrupted while the battery saving function is enabled. it can.

It is preferable that the control means be configured to interrupt the operation of the power-on timer and the power-off timer during a call even if the battery saving function is enabled.

[0007]

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

As shown in FIG. 1, the mobile phone of this embodiment is
A power supply unit 1 including a battery; an operation unit 2 for performing various key inputs such as turning on / off the power supply unit 1 and enabling / disabling a battery saving function; a monitoring unit 3 for monitoring the key operation; The system includes a timer 4 for setting the off time and the on time of 1, a control unit 5 for controlling the entire mobile phone, a display unit 6 for displaying the status of the mobile phone, and a transmitting / receiving unit 7.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG.

The monitoring unit 3 monitors whether or not a specific key input for enabling the battery saving function is performed on the operation unit 1, and when the key input is performed, the control unit 5 controls the battery saving function. (Step S
1) Put the mobile phone in a battery saving mode. Then, when an arbitrary power-off time is input using the numeric keypad of the operation unit 2 (step S2), the control unit 5 causes the timer 4 to provide two timer functions of power-off and power-on according to the input power-off time. The respective times are set (hereinafter, the former setting function is referred to as “power-off timer”, and the latter setting function is referred to as “power-on timer”), and the timer 4 is started. For example, if “2 seconds” is input as the power-off time, the power is set to be turned off for 2 seconds within 120 seconds (1 minute).

After the setting, the control unit 5 turns off the power supply unit 1 when there is an interruption from the power-off timer (step S4), and turns on the power supply unit 1 when there is an interruption from the power-on timer. (Step S5). And
Such an operation is repeated. Therefore, for example, when the power-off time is set to “2 seconds”, the power supply unit 1 repeats a cycle of being turned off for only 2 seconds in 120 seconds. Although the mobile phone becomes unreceivable for only two seconds, it recovers immediately, so that there is not much trouble in practical use.

[0012] Even when the battery saving function is enabled, the control unit 4 temporarily stops the timer 4 during a call so that the power supply unit 1 is not turned off by a timer interrupt during the call. Stop (step S6),
When the call ends, the timer 4 is restarted (step S7).

When the monitoring unit 3 detects that the key input for canceling the battery saving function (invalid) has been performed on the operation unit 2, the control unit 4 resets the timer 4 and shifts to a normal setting operation. (Step S8).

[0014]

As described above, according to the present invention, if the power-off time is arbitrarily set by the user in accordance with the state of battery consumption, the frequency of reception, etc., the power is turned off for the set time during a certain time. Is automatically turned off, so that power saving can be achieved by user setting without depending on the reception environment or the operation interruption state.

According to the second aspect of the invention, even if the battery saving function is enabled, the operation of the power-on timer and the power-off timer is interrupted during a call, so that the call interruption due to power saving can be achieved. Can be avoided.
