2. Description of the Related Art In recent years, a so-called navigation device for displaying a map has become portable, and as a communication device, a mobile phone, a PHS or the like has been commercialized. Such a mobile phone or a simplified mobile phone system may use a mobile communication device to communicate the current position and use it for a wandering elderly man tracking system, as shown in the ITE96-66, or a Lincoln Continental option. Some products, such as "rescue", that report the current position to an operation center in an emergency have been commercialized.

[0003]

However, even if the navigation device can confirm the facilities on the map, it cannot contact the other party, and even if the current position can be reported, such a system can be used. Requires a person who constantly monitors the current location, such as an operation center, and it is not easy for everyone to use.
In addition, since the communication device is used for a long time, the battery runs out early, and it is not realistic for general users, for example, an elderly person carries the battery for that purpose. Also, even if the current location is known, the person carrying the mobile phone cannot make a call if the telephone number of the other party is unknown.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a current position detecting means for detecting a current position, and, for example, a radio telephone line according to the output of the current position detecting means.

Reference numeral 5 denotes a speaker, which receives a signal received from the antenna 4 and received via the antenna duplexer 41, using a high-frequency amplifier 51, a reception mixer 52, an IF amplifier 53, and a demodulator 5
4. The signal is processed through the reception signal processing circuit 55 and the speaker 5 is processed.
To play the sound. The transmission signal processing circuit 31 and the reception signal processing circuit 55 may be those that process sound in an analog manner, but preferably those that process sound digitally using phonemic segments. For this reason, it is necessary to perform a certain code complex processing on an analog signal, but it is also possible to determine a digital signal and handle it as digital data.

Reference numeral 6 denotes a control circuit, which is the transmission signal processing circuit 31, the reception signal processing circuit 55, and the transmission mixer 33 described above.
And frequency synthesizer 42 connected to reception mixer 52
, The sound of the microphone 3 is substantially output, and the sound is reproduced from the received signal to level the speaker 5. The control means 6 comprises a microcomputer or a gate array, and also controls the liquid crystal display 1 and the input means 2. Further, the control means 6 controls a current position detecting means 8 for detecting a current position, which will be described later, and reads out telephone information according to the output of the current position detecting means to select telephone information.

[0008] Such a liquid crystal display 1, input means 2, microphone 3, and transmission circuit, speaker 5 and reception circuit,
The components such as the control means 6 are housed in a single box and can be used as a so-called mobile phone. However, a slot 7 having a built-in connection terminal is provided on the rear surface so that a card-type additional device or the like can be connected. ing.

Reference numeral 8 denotes a current position detecting means which receives a signal from a satellite, calculates a current position, and outputs information such as longitude and latitude (GPS).
ngSystem) and a geomagnetic sensor. This current position detecting means 8 is provided detachably with respect to the main body, is formed in a substantially L shape so that the GPS antenna portion 81 is exposed so as not to interfere with the antenna 4 necessary for voice communication, and is inserted into the slot 7. And connected to the control means 6. The current position detecting means 8 is turned on by a signal from the control means 6, calculates the current position under the control of the control means 6, outputs the current position information as a digital signal, and outputs the output information. It is transmitted via the signal processing circuit 31 or the like.

On the other hand, the control means 6 supplies power to the current position detecting means 8 by operating a specific key from the input means 2, and outputs information on the current position from the antenna. That is, after the telephone line is connected, the current position information is output according to the output of the current position detecting means 8 by the tone signals of "#" and "9". It also extracts digital data from the received signal, develops it into character information, develops an index, and prepares for a call.

Thus, for example, a person at home activates the personal computer to use the navigation software, or activates the personal computer to connect to the telephone line and activate the navigation software before the person goes out. The case will be described as an example. Recent navigation software can store information related to facilities and users input on the map in association with the map information, and the facilities and users linked to the map information can register the stored contents in advance. There is phonebook information of the memo function. In the following description, the description will be continued on the assumption that there is already information on the telephone directory linked to such map information as the telephone directory information.

When a person calls home at home using a communication device, dial-up software of a personal computer responds. After the connection is confirmed, by operating "# 9" of the communication device, the control means 6 turns on the power of the current position detection means 8 and causes the current position to be calculated. As a result, the current position information of the latitude and longitude is output from the antenna 4. The personal computer receives this signal and links it to the navigation application, for example, C
The map information centering on the latitude and longitude of the current position and the additional information attached thereto are read from the map information of the D-ROM,
The current position is made to correspond to the map on the maximum scale, the telephone directory information is detected from facilities and memos linked to the map information, and the information is transmitted as digital data to the telephone line. The meaning of linking to map information on the maximum scale is to specify a range, for example, 3 km in advance.
Such a link is not required if a range specification such as the following is set.

The control means 6 of the portable communication device which has received the telephone directory information extracts the digital data from the received signal, develops the digital data into character information, and converts the digital data into "XX hospital 0857-00-" for each telephone information. 1234 "" XX Hotel 0
858-99-8765 "and the like, and the data is displayed for each row on the liquid crystal display 1 in association with the touch sensor of the input means 2 (index development). When the display is completed, the telephone line is cut off, and in preparation for a call, if the call key is not operated within a predetermined time (for example, within 2 minutes), the display is blanked and returned to the standby state.
If the touch sensor of the input means 2 is operated during the display,
A dial signal is generated according to the position, and a call key 2
If 2 is operated, dial transmission is performed, and if the function key 22 or the like is pressed, another operation such as abbreviated dial registration is performed.
