DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device and a portable telephone system which require an area code when a call is made to a stationary telephone in the same area and area. is there.

[0002]

2. Description of the Related Art Conventionally, this type of portable telephone device (hereinafter referred to as a portable telephone) is not always connected to a fixed exchange like a stationary telephone, so that the receiving party can be another portable telephone. If the mobile station code number (a number different depending on the carrier such as “090” or “070”) is changed to “station number +
It is necessary to add the prefix to the beginning of the "dial number" and, for a stationary telephone, the area code to the "station number + dial number". That is, in a conventional mobile phone, it is necessary to make a call using a 10-digit or 11-digit telephone number regardless of the receiving party.

[0003]

When the calling side is a stationary telephone, only the connection to a stationary telephone in the same area area (hereinafter referred to as the same area area) is limited to the area code. A connection can be made by a combination of "station number + dial number" except for the station number. On the other hand, in the case of the mobile phone, as described above, even if the area code of the installation-type telephone to which the call is made is the same as the area code of the current area to which the mobile phone belongs, the "phone number + dial number" You must add an outside code. For this reason, when making a call from a mobile phone to a stationary phone in the same area, an area code that is unnecessary for the stationary phone is added by manual input operation (key input). Was troublesome.

[0004] Further, since the mobile phone is a mobile station, it is uncertain which area is located. That is, the conventional mobile phone cannot know the area code of the current area area to which the user belongs, and the information of the telephone directory of the current area area, such as a town page and a hello page, and the telephone number heard in the area area. If the number is only "area code + dial number", there is a problem that it is not possible to make a telephone call immediately because the area code of the area is not known.

[0005] In the portable telephone disclosed in Japanese Patent Application Laid-Open No. 9-46408, the telephone number of the other party to be frequently contacted is registered in advance to "area code + station number + dial number", and "telephone number + dial number" is registered. Is entered as a dial input number, it is determined that this dial input number has an insufficient number, and the "station number + dial number" matches the dial input number (station number + dial number). The lacking number is supplemented by adding the area code of the other party's telephone number (area code + area code + dial number). This eliminates the need to input the area code and simplifies the calling operation.

However, in this technique, the dial input number (station number + dial number) determined to have a lacking number and the registered destination telephone number (area code + station number + dial number) of "station number + dial number" Since the same judgment as "dial number" is required, unless the registered destination telephone number (area code + area code + dial number) is registered, the dial input number determined to have a missing number is toll-free. The station number cannot be added. That is, in this technique, since the dial input number is corrected using the telephone directory data registered in the mobile phone, the correction range is limited.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to eliminate a key input operation of an area code when making a call to a stationary telephone in the same area. It is an object of the present invention to provide a portable telephone device and a portable telephone system which can easily perform a calling operation and can make a telephone call immediately without knowing an area code.

Send to

Hereinafter, the area code adding function of the portable telephone 50 will be described in detail with reference to the processing operation of the CPU 53. Now, as shown in FIG.
0 is located in the management area 30 of the base station 40, and it is assumed that a call is made to the stationary telephone 60 in the management area 30, that is, to the stationary telephone 60 in the same area. For example, when the information of the telephone directory of the area to which the user belongs, such as the town page and the hello page, or the telephone number heard in the area is only “the station number + dial number”, the mobile telephone 50 transmits the telephone to the stationary telephone 60 in the same area. Sometimes calls. Such situations are unexpectedly many.

In this case, the caller inputs "station number + dial number" from key input section 57 of portable telephone 50. The dial input number (station number + dial number) input by the key is transmitted via the CPU 53 to the calling number assembling section 54A.
Stored in At this time, the CPU 53 checks whether or not the keyed dial input number is 10 digits or more, and only when it is not 10 digits or when it is determined that there is no area code, the area code information buffer 55A
Area code "03" registered in buffer 55A-1
Then, the area area name "Tokyo" stored in the storage area 55B-1 of the area code table 55B corresponding to the area code "03" is read and displayed on the display unit 58.

In this case, in the A buffer 55A-1 of the area code information buffer 55A, the area code information of the current area area to which the user belongs is registered as the latest area code information. The area 58 displays the area code and the area name of the area where the mobile phone 50 is currently located.

When only the area code is displayed on the display unit 58, the caller does not immediately know whether or not the area code is the area code of the area where the caller is located. .
However, since the area area name is displayed together with the area code, it is immediately known whether the area area name matches the current area area where the user is located. If the area area where the user is located matches the displayed area area name, the caller operates the key input unit 57 to change the displayed area area name to the desired area code. Determine as the area name corresponding to the station number.

Then, the CPU 53 outputs the area code corresponding to the determined area / region name to the calling number assembling section 54.
Send to A. The caller number assembling section 54A
Is added to the dialed input number (station number + dial number) from the key input unit 57 stored earlier, and this is added to the destination telephone number (area code + area number + dial) to the call processing unit 54B. Number).

The calling processing unit 54B includes a calling number assembling unit 5
The destination telephone number (area code + area code + dial number) from 4A is converted into a dial tone signal, and the radio processing unit 52
Send to Radio processing section 52 modulates the dial tone signal from call processing section 54B into a radio signal and transmits the radio signal to base station 40 via antenna 51. The destination telephone number (area code + area number + dial number) from the caller number assembling unit 54A is sent to the retransmission number monitoring unit 54CPU, and after the call processing unit 54B has made a normal call, redialing is performed. Stored as a number.

The base station 40 demodulates the radio signal from the portable telephone 50 by the radio section 41 and supplies the demodulated radio signal (dial tone signal) to the exchange 20 via the control section 42. The exchange 20 decodes the telephone number of the other party based on the dial tone signal from the base station 40 and sends a call signal to the public line network 10 or the exchange 2
It is determined whether or not to send to the stationary telephone 60 connected to the “0”. In this case, the dial input number (station number + dial number) key-input from the key input unit 57 of the mobile phone 50 is set to the stationary telephone 6 in the management area 30 of the base station 40.
Since it is for 0, a call signal is sent to the stationary telephone 60 in the management area 30 based on the destination telephone number (area code + area number + dial number) sent from the mobile telephone 50.

As described above, according to the present embodiment, when the user inputs "station number + dial number" by key, the name of the current area or area to which the user belongs is displayed. If the current area area matches, the area area name corresponding to the desired area code is determined by key input operation, and the area code of the determined area area is dialed. The number is automatically added to the number (station number + dial number), and the key input operation of the area code when making a call to the stationary telephone in the same area becomes unnecessary, and the calling operation becomes easy. Further, according to the present embodiment, by determining the area code based on the area / region name, it is possible to make a call immediately without knowing the area code. In this embodiment, the corresponding area code is displayed together with the area / region name, but the area code need not always be displayed.

Further, in the above description, a call is made from the portable telephone 50 to the stationary telephone 60 in the same area area.
It is possible to make a call to a stationary telephone in the previous area without keying in the area code.

In this case, the key input unit 5 of the portable telephone 50
When the user inputs the "area code + dial number" from key 7, the area code "03" registered in the A buffer 55A-1 of the area code information buffer 55A and this area code "03"
Storage area 55B- of the area code table 55B
The area area name “Tokyo” stored in No. 1 is read out and displayed on the display unit 58. Here, since the area area name “Tokyo” is not the area area name of the desired area code, the display of the area area name is switched by a key operation from the key input unit 57.

Then, B of the area code buffer 55A
The previous area code "044" registered in the buffer 55A-2 and the area area stored in the storage area 55B-2 of the area code table 55B corresponding to the area code "044". The name “Kawasaki” is read and displayed on the display unit 58. That is, the display area 58 displays the name of the previous area or area to which the mobile phone 50 belongs.

Here, when the area area name is determined as the area area name of the desired area code, the dial input number (station number + dial number) from the key input unit 57 is replaced with the area code of the determined area area. Is added. As a result, it is possible to make a telephone call to the stationary telephone in "Kawasaki", which is the area to which the mobile telephone 50 belongs, without keying in the area code.

In FIG. 4, the area code buffer 55 is shown.
A is two of A buffer 55A-1 and B buffer 55A-2.
However, the number of buffers may be further increased. By doing so, the area code of the area to which the user has belonged is accumulated in the area code information buffer 55A one after another, and the area to which a call can be made without key input of the area code can be increased. .

In the above-described embodiment, the case where "station number + dial number" is inputted from the key input section 57 has been described. However, "special number" such as a call dial number and weather information may be inputted. Good. In this case, a "city code" is added to the keyed dial input number ("special code"), and the "special code" to which the "city code" is added is transmitted from the calling number assembling unit 54A to the call processing unit. It is sent to 54B as the other party's telephone number (city code + special number).

FIG. 5 is a flowchart showing the registration and update processing of the area code information in the area code information buffer 55A in FIG. In the standby state (step 101), when additional information channel information is received (step 102), area code information of the current area area to which the terminal belongs is fetched (step 103). Then, it is determined whether or not the area code information has already been registered in the A buffer 55A-1 of the area code buffer 55A (step 104).
No. 4), the area code information fetched in step 103 is fetched into the A buffer 55A-1 as the latest area code information (step 107).

In step 104, the A buffer 55
If the area code information has already been registered in A-1 (YES in step 104), it is determined whether the registered area code information matches the contents of the newly acquired area code information ( In step 105), if they match (NO in step 105), the newly acquired area code information is discarded (step 108).

If the newly acquired area code information does not match the registered area code information (YE step of step 105), the contents of the registered A buffer 55A-1 are updated to the oldest 5 to the B buffer as information
After moving to 5A-2 (step 106), the newly fetched area code information is updated to the A buffer 55A.
-1 (step 107). Such a procedure is performed every time the additional information channel information is received.

FIG. 6 is a flowchart showing the dialing process of the other party at the time of calling in FIG. The dial input number from the key input unit 57 is registered in the calling number assembling unit 54A by a key input operation when the input of the dial input number is completed (steps 201 and 201).
02). The dial input number in step 201 is displayed on the monitor 58 for confirmation for the purpose of confirmation.

On the other hand, the CPU 53
It is determined whether or not the area code is included in the dial input number for which registration has been completed (step 203). If it is determined that the area code is included ( YES in step 203),
The dial input number registered in the calling number assembling unit 54 is sent to the calling processing unit 54B. The calling processing unit 54B converts the destination telephone number (area code + area number + dial number) from the calling number assembling unit 54A into a dial tone, and starts a calling operation (step 209). Then, after the call is normally completed, the retransmission number monitoring unit 54 is set so that redialing can be performed.
Store the telephone number of the called party to C (step 2)
10).

If it is determined in step 203 that the area code is not included, the area code information is taken out from the A buffer 55A-1 of the area code information buffer 55A, and the area code corresponding to the area code is taken out. Then, the area area name stored in the area code table 55B is also extracted at the same time, and the extracted area code and area area are expanded and displayed on the display unit 58 (step 204).

If the displayed area area name matches the current area area where the caller is located, the caller operates the key input unit 57 to change the area area name to a desired area code. (YES in step 205). The area code corresponding to the determined area / region name is combined with the dial input number registered in the calling number assembling unit 54A by key input in step 201, and is re-registered as a destination telephone number (step 208). ), Converted into a dial tone by the calling processing unit 54B, and the calling processing unit 54B starts a calling operation (step 209). Then, after the call is normally completed, the called party telephone number is stored in the retransmission number monitoring unit 54C so that redialing can be performed (step 2).
10).

If the call selection from the A buffer 55A-1 is not determined (NO in step 205), the area code information immediately before the B buffer 55A-2 is extracted, and the immediately preceding area code is extracted. The area area name stored in the area code table 55B is also extracted at the same time in accordance with the area code information, and the extracted area code and area area name are displayed again on the display unit 58 (step 206).

When the displayed area area name matches the desired area area name, the caller operates the key input section 57 to change the area area name to the area area corresponding to the desired area code. As the first name (step 20
7 YES). The area code corresponding to the determined area / region name is combined with the dial input number registered in the calling number assembling unit 54A by key input in step 201, and after being registered again as a destination telephone number (step 20).
8) The call is converted into a dial tone by the calling processor 54B,
The calling processing unit 54B starts a calling operation (step 20).
9). Then, after the call is normally completed, the called party's telephone number is stored in the retransmission number monitoring unit 54C so that redialing can be performed (step 210).

In step 207, if the displayed area area name is not determined as the area area name corresponding to the desired area code (N in step 207).
O) The area code is manually registered in the calling number assembling section 54A from the key input section 57 (step 211). The registered area code and the dial input number registered in the calling number assembling unit 54A by the key input in step 201 are combined, and after being re-registered as the destination telephone number (step 208), the calling process is performed. The data is converted into a dial tone by the unit 54B, and the call processing unit 54B starts a call operation (step 209). Then, after the call is normally completed, the called party's telephone number is stored in the retransmission number monitoring unit 54C so that redialing can be performed (step 210).
