Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mobile phone,
In particular, it relates to a mobile phone with an automatic dial function and a dialing method for an external phone using this mobile phone.

[0002]

2. Description of the Related Art Some mobile phones are equipped with an electronic telephone directory function capable of storing a large number of telephone number information. When making a call, the stored telephone number is searched or called in the order of IUEO. Alternatively, a so-called speed dial can be performed by combining the # and * mark keys with a short number. However, in areas outside the mobile phone service area, there is no choice but to resort to other means, and even when the mobile phone's built-in battery power is consumed until communication is not possible, there is no choice but to resort to other means. . Further, even if the mobile phone can be used, there are cases where it is desired to use another telephone means with a low telephone charge.

In such a situation, the mobile telephone can only use the function as an electronic telephone directory for searching the telephone number of the destination to be called and displaying the telephone number, even if it stores the speed dial. I was not able to use that function.

[0004]

Therefore, the problem to be solved by the present invention is to provide a mobile phone with an automatic dialing function, which enables dialing using the speed dial function even in a situation where a call cannot be made on the mobile phone. It is to provide a telephone and a dialing method.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a circuit block diagram of a mobile phone with an automatic dial function of the present invention, FIG. 2 is a conceptual diagram when dialing a public telephone using the mobile phone with an automatic dial function of the present invention, and FIG. It is an external view of a mobile phone with an automatic dial function of the present invention.

In FIG. 1, a mobile phone with an automatic dialing function according to the present invention has a bidirectional communication circuit with a base station, a radio transmitting / receiving circuit 1 including a voice processing circuit, an antenna 2 for emitting and receiving radio waves, and receiving a call. A handset (speaker) 3, a transmitter (microphone) 4 for transmitting, an electronic telephone directory memory 5 for storing telephone number information and corresponding personal name information, and a register 6a for temporarily storing telephone number information and the like. In addition, a logical control unit 6 for controlling the entire telephone is provided, and further, a display 7 connected to the register 6a for displaying a telephone number and the like, and a logical control unit 6 connected for inputting a telephone number and making a telephone call, It is provided with a dial key 8 for operating an incoming call and a battery 9 which is a power source of the entire telephone.

In the example of the present invention, as the specific operation procedure, for example, the symbol keys 8b and 8c and the numeral key 8a are combined and pressed to switch to the DTMF dial mode. Then, a control signal is sent from the control line 10b connected to the transmission / reception circuit from the logic control unit to D
The function of the transmission / reception circuit is stopped during the TMF dialing.

Further, instead of the operation procedure of the specific key, an example in which a DTMF dial key 11a is provided below the dial key 8 is shown as shown in the external view of the portable telephone with an automatic dial function of FIG.

Next, the usage will be described with reference to the conceptual diagram of FIG. 2 when dialing a public telephone using the portable telephone with the automatic dialing function of the present invention. First, the dial key 8 is operated to read the telephone number of the destination to be called from the electronic telephone directory memory 5, set the number in the register, and confirm it on the display. Next, the public telephone main body 12
The handset 14 is removed from the hook 13 and the handset (microphone) 14a of the handset 14 and the handset 3 of the mobile phone face each other. Press the operation button of the DTMF dial key 11a of the mobile phone to activate the DTMF dial mode and
The F signal causes the handset to send out. At this time, the wireless transmission / reception circuit 1 receives the control signal from the control line 10b and its transmission / reception function is stopped.

The DTMF signal corresponds to each number forming a telephone number and identifies each key by a combination of tones in two voice bands. This signal is 697H
It is a simple tone from z to 1477HZ, and is familiar to the beeping, popping, and popping sounds that are usually heard when pressing the keys of a push-button telephone.

The DTMF signal 15 is DTMF.
It is sent from the handset (speaker) 3 in the form of an acoustic signal 15a to the handset 14a of the handset 14 of the public telephone 12, and in the form of an electric signal via the cord 16 the public telephone main body 12a.
Is sent to the base station via the communication line, and the predetermined destination is called by the exchange.

When the DTMF automatic dial mode is selected, the function of the wireless transmission / reception circuit 1 is stopped, so that the power consumption is extremely small, the battery power can be saved, and the battery 9 is greatly consumed. However, it has the effect that only the automatic dialing function can be used.

[0015]

According to the present invention, there is provided a mobile telephone with an automatic dialing function and a dialing method which can use the automatic dialing function when using another telephone even when the mobile telephone cannot be used or is not used. can do.
