Abstract

PROBLEM TO BE SOLVED: To eliminate a call interruption due to a battery shutoff by recognizing a residual battery capacity in the case of an incoming call through the use of a simple method.

SOLUTION: When the incoming call exists (S1), parameters V0 and V1 are initially set to obtain a state where the voltage of the battery 6 is in a fully charged state (S2). An incoming ringer is set to a normal tempo in the case of full charge (S5). When the state is not the fully charged one (S3) and also the consumption of the battery 6 exceeds an offset value, a value obtained by adding the offset value to V1 becomes smaller than V1 (S4). Then the parameter for heightening the tempo of the incoming ringer is set based on a battery remaining capacity value (S6) and the incoming ringer is operated (S3).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to is, that the user can check the remaining battery power before you answer the phone by making the tempo of the ringer or melody that sounds when receiving a call is changed according to the remaining battery level is ringing It relates to a portable phone that can be.

[0002]

In conventional mobile telephone, when in use either, or a mobile phone check the battery remaining display displayed on the screen is performed by a method of notifying by the vibration of the vibrator. .

[0003]

THE INVENTION Problems to be Solved] In this manner, in the conventional mobile phone, the caller information such as caller ID notification content in the case to respond to incoming Even though you can see the battery level indicator on the screen the it is often responds to check the battery remaining amount would be too power-off due to a voltage drop during a call in order not verified or by line disconnection, occurs. Next, become hooked on with the conversation even in the case of notification by the vibrator, there was that same thing occurs.

[0004]

The present invention SUMMARY OF] is intended to solve these problems, comprises a battery to be used attached to internal or body, detects that the voltage of the battery approaches the specified value or less then the mobile phone having a battery level warning means for giving a warning to the user, the battery level warning means by a battery tempo ringer or melody sounding when receiving a call when it detects that the voltage of the battery approaches the predetermined value to provide a mobile phone that is changed according to the remaining amount.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, will be explained with reference to the drawings showing preferred embodiments of the present invention. Figure 1 is a block diagram of a cellular phone as an embodiment of the present invention, FIG 2 is a flowchart for explaining the operation of the mobile phone as an embodiment of the present invention.

[0006] In FIG 1, an antenna 2 for transmitting and receiving is provided a voice or data from the other party phone (not shown) in the cellular telephone 1, the telephone unit 3 for modulating and demodulating a voice or data received by the antenna 2 It is provided. Further, it is provided a battery 6 for driving the telephone 1, and detects the battery remaining amount of the battery 6 by further battery remaining amount detecting section 7. This by the battery remaining amount detecting section 7 detects the remaining amount of the battery 6, when the battery level is below a predetermined value and drives the vibrator portion 5. Moreover, also it provided a speaker for outputting voice.

[0007] Next, the operation described with reference to FIGS. First, there is an incoming call from the other party phone (not shown) (S1) and the voltage of the battery 6 parameters V0 and V1 are initially set to the fully charged state (S2). Here, it is determined whether the voltage of the battery 6 is fully charged (S3), sets the call ringer normal tempo when a fully charged (S5).

[0008] If, when not fully charged state (S
3) If the value of the remaining battery capacity when the battery 6 from the state of such a full charge is consumed and V1, when consumed by from the fully charged state is smaller than the offset value V0
It is set to less than the value obtained by adding the offset value (S4) incoming ringer normal tempo V1 of (S5).

[0009] is further consumed battery 6, the consumption amount of the battery 6 exceeds the offset value, called based on (S4) the battery remaining amount value to a value obtained by adding the offset value is less than V1 to V1 Ringer parameters for faster tempo is set (S6). Then, set the value of V1 indicating the latest battery remaining amount V0 (S7).

[0010] incoming ringer is sounding in accordance with the incoming ringer tempo already set from the speaker 8 as shown in FIG. 1 (S8).

[0011]

As in the above, according to the present invention, since the present invention can be confirmed in advance the remaining battery level before you call that an incoming ringer to sound when a call arrives was so tempo is faster, depending on the battery level it is possible to solve the problem of call disconnection by power fails during a call to.

Claims (1)

[The claims]
1. [Claim 1 further comprising a battery for use attached to internal or body, in the mobile phone having a battery level warning means for giving a warning to the user detects that the voltage of the battery approaches the specified value or less, the mobile telephone, characterized in that is changed according to the battery remaining amount tempo ringer or melody sounding when receiving a call when it detects that the voltage of the battery approaches a specified value by the battery remaining amount warning means.
