Abstract

PROBLEM TO BE SOLVED: To facilitate uttering a voice even under such an emergency circumstance as a caller should utter a voice to an emergency liaison destination such as an opposite talker of a police station, after a line is connected by pressing down an exclusive key in the case of communication of the emergency in a portable telephone set. SOLUTION: A dial number 331 of emergency liaison destination stored in advance in a memory part 33 is sent to connect a line by pressing down an emergency communication key switch 2. Then a dual tone multi-frequency(DTMF) part 35 generates signal data consisting of an emergent signal and an own telephone number in terms of a Morse signal and transmits the data to an opposite talker 7 of an emergency liaison destination automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for emergency communication on a portable telephone.

[0002]

2. Description of the Related Art In general, as a conventional emergency telephone communication method, when a dedicated one-touch key is depressed, a call is automatically made to a registered public rescue / emergency agency, and the caller is connected to a line. After confirming that the connection was established, the user had to utter his own voice to communicate the situation to the other party.

[0003]

However, in the conventional device, when the sender cannot speak, it is difficult to explain the situation to the other speaker.

At a low temperature of -10 ° C. or less,
Since acoustic components such as a microphone and a receiver become inoperable due to their physical properties, it is very difficult to explain the situation to the other party even if a line is connected.

[0005]

In order to solve the above-mentioned problems, according to the present invention, an emergency contact stored in advance, for example, a dial number of a police station or a fire station is transmitted by pressing an emergency call key switch. In addition, an emergency signal and its own telephone number are transmitted to the other party by a Morse code or a voice signal.

[0006] In addition, when a mobile telephone is directly connected to a general public line network, the line can be connected not only via a mobile telephone network but also via a general public line network.

[0007] As an apparatus for realizing the above, a memory unit in which dial number data of an emergency contact and signal data in which an emergency signal and its own telephone number are registered in Morse code are previously stored in a portable telephone. A DTMF (Dual Tone Mult-Fre
quency) unit, means connected to the general public telephone network, means for detecting that the other party of the emergency contact has entered a talking state, and a voice response unit in which voice signal data in which said signal data is registered in an official language is stored in advance. And so on.
