Then, the dial button 21 is pressed to "11".
When the number 0 "is dialed, the emergency dial detection circuit 11 in the GPS section 10 identifies the dial" 110 "and drives the position information request circuit 12 to instruct the GPS utilizing device 13 to output the position information. Upon receiving the instruction, the GPS utilizing device 13 calculates the current position in latitude and longitude based on the GPS signal received from the GPS satellite, and sends it to the signal processing device 14 as position information.

On the other hand, in the mobile telephone unit 20, the telephone circuit 2
3 receives the dial “110” from the dial button 21, and sends the received dial “110” from the transmission / reception circuit 25 via the communication circuit 24 to the communication network 5 via the communication path. As a result, the communication network 5 extends and connects the transmission / reception circuit 25 to the reception circuit 31 of the emergency contact 3 to form a communication path. The call voice of the handset 22 and the position information are multiplexed and output to the communication path by the signal processing device 15.

On the other hand, at the emergency contact 3, the position signal received through the formed communication path is separated from the voice by the demodulation and decoding circuit 32 and taken out, and displayed on the position information display unit 33 on the screen. The voice information is loudly broadcast by the speaker 36 via the call circuit 34 and the telephone circuit 35.
As a result, the operator of the emergency contact 3 listens to the call voice broadcast from the speaker 36, and the position information display unit 3
The current position of the mobile telephone 1 can be confirmed accurately on the map of No. 3.

Next, an operation procedure when the emergency button 15 is operated will be described.

When the emergency button 15 is operated, on the other hand, the position information request circuit 12 receiving the operation information receives the GP.
Since the S utilization device 13 is instructed to output the position information, the position information can be output to the signal processing device 14. On the other hand, the automatic dial transmission circuit 26 that receives the operation information of the emergency button 15
First, the telephone circuit 23 is driven to make a call to the communication network 5 via the call circuit 24 and the transmission / reception circuit 25, and the registered emergency dial “110” is dialed to establish a call path as an emergency contact. Connect to No. 3 "110". As a result, the communication information of the communication voice of the communication circuit 24 and the position information of the GPS utilization device 13 can be multiplexed by the signal processing device 14 and output to the communication path.

By using the emergency button 15, it is possible to prevent erroneous dialing which is caused in an emergency.

As shown in the figure, the automatic dial transmission circuit 26 of the mobile telephone 1 has a repetitive transmission circuit 27, and once the transmission of the position information is completed, the connection is temporarily cut off. After that, the call is reissued, the automatic dialing is started, and the position information is repeatedly sent to deal with the case where the emergency contact 3 cannot be connected due to congestion or the like. Further, in this case, the power consumption of the mobile phone 1 can be suppressed by appropriately setting the information transmission pause time.

On the other hand, the emergency contact 3 has a position information storage unit 41, and the position information display unit 42 has a demodulation / decoding circuit 32.
When the location information is received from the location information, the location information and the telephone number of the mobile telephone 1 that is the source are stored in the location information storage unit 41 and displayed on the display screen. At this time, in the position information storage unit 41, the oldly stored position information having the same source telephone number is deleted. Further, on the display screen, the location of the mobile telephone 1 is indicated on the map and the telephone number is displayed in characters.

In the above description, it is explained that the location is indicated by the mark display on the map of the display screen.
Character display by longitude may be used.

Next, a means for broadcasting position information by voice will be described with reference to FIGS. The location is not only displayed on the screen but also can be heard by voice, which is an effective means in an emergency.

Displays the position information and the telephone number output from the demodulation / decoding circuit 32 to the position information display unit 33, for example, "emergency information,
Emergency information, phone number xxxx, current location, east longitude xx
An emergency situation occurs at x degrees xx minutes and north latitude xxx degrees xx minutes "and is output to the speaker 36. The voice message is broadcast from the speaker 36.

An example in which an audible signal is also heard when the position information is displayed on the screen of the emergency contact 3 will be described with reference to FIGS. 2 and 6. This audible signal indicates that position information is displayed on the screen by ringing, and is effective for prompt response at the emergency contact point 3.

As shown in the figure, the emergency contact 3 is provided with an audible signal generating circuit 44 and a signal ringing unit 45, and the signal ringing unit 45 is assumed to be a buzzer. Upon receiving the position information output from the demodulation / decoding circuit 32 to the position information display unit 33, the audible signal generation circuit 44 sends a drive signal for ringing the buzzer to the signal ringing unit 45.

In the above description, the signal processing device performs A / D (analog / digital) conversion of call information, packet conversion with position information, multiplexing and superposition, and then D / A (digital / analog) conversion again. It is explained that the transmission / reception circuit uses a band-pass filter for radio channel allocation to set the radio channel and the transmission / reception signal is subjected to modulation / demodulation processing by the modulation / demodulation means.
