Abstract

PURPOSE:To reduce mis-input because of reduction in input data number of telephone numbers by reading out a toll number from a memory when a telephone number not added with the toll number is inputted and dialing the telephone number while the toll number is added to the telephone number. CONSTITUTION:Suppose that the number data of 0246 is registered into a telephone number memory 5 by a toll number registration. When the user desires to make a phone call to a telephone number 0246-31-1000, a ten-key 1A of an operation section 1 is operated and number keys of 3, 1, 1, 0, 0, 0 are consecutively depressed. Since a number 311000 is displayed on a display device 6, the user after confirming the entry of the number depresses a start key 1G. A control section 11 receives the number data via an input and output interface 10 to judges the inputted opposite destination telephone number to be below a prescribed digit number. Then the control section 11 reads out a registered toll number in the memory 5 and added to the inputted opposite destination number. Thus, the telephone number data of 0246311000 is sent from a radio transmitter-receiver 9.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for making a telephone call, and particularly to a method for making a telephone call that is suitable for application to a car telephone.

<Prior Art> In a car telephone system, when a call is made from inside the car, the call is connected to the telephone set of the other party via a radio relay base located at an appropriate location and a telephone line, so that the call can be made to the other party. Naturally, it is also possible to call the phone inside the car from an external phone and make a call using the reverse route.

By the way, there are two conventional methods for calling an external telephone number from a telephone in a car. One is
This method involves operating the keys on the handset of a car phone to enter the telephone number of the other party, confirming the telephone number on the display, and after confirming, operating the call key to make the call. This method uses speed dialing to enter a phone number and make a call in the same way.

<Problems to be Solved by the Invention> However, in the conventional telephone calling method, in which the telephone number of the other party is entered by operating keys provided on the handset of a car phone, the other party's station is the calling station. Due to the unique characteristic of car telephones, in which the area code must be added and the destination phone number entered even when making a local call to a station with the same area code, there is a large amount of input number data for the destination number. It turned out to be very similar. Furthermore, considering that the environment in which the device is used is inside a vehicle, which is small and has a lot of vibration, inputting a large amount of data may cause input errors.

In addition, other calling methods, such as entering a phone number using speed dial and then making a call, do not require complicated input operations and are very convenient, but the phone number of the other party is not memorized. If you forget the speed dial number you have, you will not be able to make a call, and the number of speed dials is limited, so there is a problem in that you cannot remember too many phone numbers.

<Means for Solving the Problems> In the present invention, the above problems are accomplished by providing a storage means for storing the area code of a telephone number, an operation means for specifying the other party's telephone number, and a telephone number to which no area code is added. When is input,
Read the area code corresponding to the phone number 1 from the storage means and add it to the phone number! It is comprised of a control means that outputs a telephone number, and a radio that transmits the telephone number when there is an instruction to make a call.

<Trust> The area code of the telephone number is stored in the memory, and when the other party's telephone number is input using the operation keys, if the area code is not added to the input number, the control means stores the area code in the memory. Reads the area code, adds it to the input number, and outputs it.

<Embodiment> FIG. 1 is a block configuration diagram of a car telephone to which the telephone calling method according to the present invention is applied.

In the figure, reference numeral 1 denotes an operation section, which has various operation keys. Operation 1 here! I will briefly explain the functions of the various $1 keys.

The numeric keypad 1A is used when inputting a telephone number, etc. The numeric keypad 1B is a hold/mute key, and is a key for muting the speaker 2 and microphone 3 to put the call on hold during a call. This is because the speaker 2 and microphone 3 are both hands-free (no need to hold hands), so when a call is on hold, it is not possible to press the mouthpiece of the receiver like with the handset telephone 4. ing. 1C is a memory storage key, which is used to store a telephone number in the telephone number memory 5 in correspondence with speed dialing.

1D is a memory recall key, and 1 and 1F are function keys that allow the contents of the telephone number memory 5 to be displayed on the display 6 in the order of data input by pressing this key and then operating the up/down key 1E. ,
This is the key used when registering a phone number. 1G call start,
Alternatively, a call start key that enables a conversation with the other party when a call is received is stored in the re-calling memory 7 in order to call the other party again. A repeat key 1J for displaying a telephone number on the display 6 is a call end key used to end or interrupt a call.

It is assumed that the operating section 1 is provided as a driver-only operating section on the driver's seat side door and is operated by the driver. Further, a speaker 2 and a microphone 3 are each provided in a hands-free configuration near the driver's seat, and are connected to a control tMI section of an inter 7/8 box 8, which will be described later.

Is 8 the control unit 1 or the handset? The interface 7 processes the data input manually from the talker 4 and outputs it to the wireless transmitter/receiver 9.
It's Eighth Box. Next, each part of the interface box will be explained. 10 is an input/output interface, 1
1 is a microcomputer-configured control unit that performs call origination and incoming call processing and abbreviated number processing; 5 is a telephone number memory that stores abbreviated dial telephone numbers and area code numbers; and 7 is for re-calling the destination. This is a re-call memory that is stored in the re-call destination telephone number.

6 is the telephone number stored in the telephone number memory 5 or the re-calling memory 7 at the time of making a call or as needed? A display section 9 displays No. 1 data, and a wireless transceiver 9 performs wireless communication of voice and control codes with a relay base (not shown). Reference numeral 4 is a 14-passenger handset telephone, which can be attached to the rear seat or passenger seat side, but it does not have the multi-functionality of the operation panel 1, and consists of a numeric keypad 4A, an end key 4B, a microphone 4C, a speaker 4D, and a numeric keypad. Press 4A to make a call, or use it as a receiver when receiving a call.

FIG. 2 is a flowchart of the call processing according to the present invention, and FIG. 3 is a flowchart showing a method of operating the operation unit 1 when storing an area code number in the telephone number memory 5. The structure of the present invention will be described in detail below with reference to FIG. 1 and along the flowcharts of FIGS. 2 and 3.

First, with reference to FIG. 2, a method of registering an area code into the telephone number memory 5 will be explained. The user operates the numeric keypad 1A of the operation unit 1 to input an area code, for example, 0246.

(Step 100). The input number 0246 is displayed on the display 6. Next, if there is no mistake in the number you entered, press the function key 1F. Step 1
01), and by further pressing the memory storage key IC (step 102), the number data of 0246 is registered at a predetermined address in the telephone number memory 5. By performing the above operations, the registration of the area code number in the telephone number memory 5 is completed.

Next, a flowchart of the call processing of the present invention will be explained with reference to FIG. It is now assumed that number data 0246 has been registered at a predetermined address in the telephone number memory 5 as a result of the above-mentioned area code registration work. Therefore, the user is 02
If you want to call 46-31-1000, call the operation section 1.
1A and press the number key 311@L (step 200).

Next, the destination number 311000 input by the user is displayed on the display 6, so the user confirms that it is not an incorrect input and presses the start key 1G on the operation unit 1 (step 201). The iqm unit 11 that received the command to start a call receives the number data through the input/output interface 10, and checks whether the number of received number data is greater than or equal to a predetermined number (for example, 9) and whether it is a predetermined number. It is determined whether the number of data is less than (step 202). Here, the ii+ control unit 11 determines that the destination telephone number input in step 200 is less than the predetermined number of data. Therefore, the llivA section 11 reads out the area code registered in the telephone number memory 5 (step 203) and adds it to the input destination number (step 204). Therefore, the telephone number data 0246311000 is transmitted from the wireless receiver 9 (step 205), and once the user is connected to the other party, he or she can enjoy a normal conversation (step 206). Further, in step 202, if it is determined that the number of data is greater than or equal to the predetermined number, the input data is transmitted as is via the wireless device 9. When the call ends, the call can be ended by pressing the end key 1J of the operation section 1. Note that even if the handset telephone 4 is used after making a call using the operation unit 1, it is possible to have a normal conversation. Also, if you press the start key in operation 7111, the handset phone S! ! It is also possible to make a call from 4.

<Effects> According to the present invention, the area code of a telephone number is stored in the menu, and when a telephone number to which no area code is added is input, the area code is read from the memory and the area code is read out from the memory. Since the phone number is added to the rt@ phone number that does not have an area code added to it, when making a call, you can make a call in the same way as when using a normal home telephone, regardless of whether you are outside the area. Be able to use equipment. Furthermore, since the amount of input data for telephone numbers is reduced, incorrect input of telephone numbers can be reduced. Note that the area code to be memorized may be the area code of a frequently used area.
