Description

Description: TECHNICAL FIELD The present invention relates to a re-calling method of a communication device using a public telephone line as a transmission line and provided with a selection signal transmitting unit.

2. Description of the Related Art For example, some communication terminals such as telephones that use a public telephone line as a transmission line have a recall function for recalling a destination that has just been called.

However, conventionally, the recall function is applied to only one destination called immediately before, so that the following inconvenience may occur.

In other words, when one person shares one telephone, when another person uses the telephone after himself / herself, if the recall function is used, the destination called by another person can be used because it is recalled. Therefore, it is necessary to re-enter the destination telephone number in all digits.

Also, when calling alternately two or three destinations,
The recall function cannot be used. In this case, it is conceivable to use the speed dial function. However, in order to use this speed dial function, it is necessary to register a telephone number in advance as a speed number, so that a destination that makes calls so frequently is used. It has not been used for any other purpose.

Conventionally, there is also a telephone that stores a plurality of telephone numbers that have been called in the past, displays the number on a display unit, and selects the displayed content to make a call again.
A display for displaying the re-call number is required, and the equipment cost is increased. In addition, when a plurality of people share the same telephone, simply looking at the display does not make it possible to confirm which one is the one who was trying to call immediately before, which is rather inconvenient. Was.

[Purpose] The present invention has been made to solve such a problem of the related art, and has as its object to provide a recalling method capable of easily registering a large number of recalling destinations.

[Configuration] In the present invention, in a recalling method of a communication device using a public telephone line as a transmission path and provided with a selection signal transmitting means, a recalling number storing means for storing a telephone number immediately before calling, Numeric keypad recall number storage means for storing a recall number corresponding to each key of the numeric keypad, and recall calls for calling the recall number stored in the recall number storage means or the tenkey recall number storage means Means, re-call operation input means for commanding a re-call operation,
A registration operation input means for inputting a command to register a recall number in the ten key recall number storage means is provided, and when the registration operation input means is operated after a call is made, the registration key corresponding to a subsequently input ten key is provided. The stored contents of the re-call number storage means are registered in the re-call number storage means, and when the re-call operation input means is operated, and subsequently the numeric key is operated, the corresponding numeric key is operated. The recalling number stored in the numeric keypad recalling number storage means is output to the recalling means to perform a recalling operation. When the numeric keypad is not operated, the recalling number is stored in the recalling number storage means. The re-calling number is output to the re-calling means to perform a re-calling operation.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a telephone according to an embodiment of the present invention.

In the figure, a handset 2 for a telephone call is set on the left side of a housing 1 of the telephone, and a numeric keypad 3 for inputting a telephone number and a command for redial (recall) are provided on the right side of the housing 1. And a registration key 5 for instructing registration of a re-call number corresponding to the numeric keypad 3 are provided.

Further, a hook switch 6 for detecting an off-hook of the handset 2 is provided at a position where the handset 2 can be turned on and off by the handset 2, and a hook switch 6 is provided immediately below a slit 7 formed in a lower right corner of the housing 1. A speaker 8 for outputting various tones is provided.

 FIG. 2 illustrates a control system of the telephone.

In FIG. 1, a CPU (Central Processing Unit) 11 executes internal function processing of the telephone, and its program is stored in a ROM (Read Only Memory) 12.
The work area and the like are formed in a RAM (random access memory) 13.

The parameter memory 14 stores parameters such as abbreviated numbers that are unique to the telephone, and is composed of a nonvolatile storage device.

The operation display unit 15 inputs the input signals of the numeric keypad 3, the redial key 4, the registration key 5, and the hook switch 6, and sounds the speaker 8.

The network controller 16 is for connecting the telephone to a public telephone line, and outputs a selection signal of a dial pulse or a push button signal to an exchange. The handset 2 is connected to the network controller 16.

In the RAM 13, as shown in FIG. 3, a redial number area ARr in which a telephone number called immediately before is registered,
Further, a ten-key redial area TKr in which a ten-key redial number for a redial registered corresponding to each numeric key is registered is provided.

With the above configuration, the CPU 11 is configured as shown in FIGS.
By performing the processing of (c), a destination call and a re-call processing are performed. Here, it is assumed that the abbreviated number has already been registered in the parameter memory 14, and the abbreviated number is composed of "#" followed by two digits. Further, in the following invention, description of parts not directly related to the present invention will be omitted.

First, the CPU 11 monitors that the handset 2 is picked up and the hook switch 6 is turned off and goes off-hook (decision 101). If the result of this decision 101 is YES,
Registration key 5, Redial key 4, or Numeric key 3
Waits for an operation input (judgment 102, 103, 104
NO loop).

The operator operates the numeric keypad 3 to make a call, and when the result of determination 104 is YES, it is determined whether the first operated key is the “#” key (decision 105).

When the result of the determination 105 is NO, the operator directly inputs the destination telephone number, so the key code of the key input by the operation is transferred to the network controller 16 and the selection signal corresponding to the key is transmitted to the line controller. (Process 10
6) It is monitored whether the operation input of the next numeric keypad 3 has been performed, whether the network controller 16 has detected the polarity reversal and the connection with the destination has been completed, or whether the operator has returned the handset 2 and went on-hook (determination). 107, 108, 109 NO loop).

When the result of the determination 107 is YES, the process returns to the process 106 and transmits a selection signal corresponding to the key input at that time to the line.

When the result of the determination 108 is YES, since the connection with the destination has been made, the operator's telephone conversation is started. Therefore, the operator ends the telephone call, returns the handset 2, and waits until the hook switch 6 detects on-hook (determination 110). NO
loop).

If the result of decision 110 is YES, then registration key 5
It is checked whether or not the processing relating to the operation input has been executed (decision 111). If the result of the decision 111 is NO, the destination telephone number called at that time is stored in the redial number area A of the RAM 13.
Register in Rr (process 112) and return to the initial state.

When the result of the determination 109 is YES, it means that the call is terminated by the operator because the other party does not answer the incoming call.

When the result of determination 105 is YES, it is when the operator enters the abbreviated number, so the operator waits until the subsequent two-digit number is input (determinations 113 and 114).

When the input of the abbreviated number is completed, the telephone number corresponding to the inputted abbreviated number is read from the parameter memory 14, and the telephone number is stored in the telephone number temporary registration area set therein (step 115).

Then, the key code of the telephone number stored in the telephone number temporary registration area is transferred to the network control device 16 one digit at a time, and a selection signal is output (process 116). Alternatively, the operator waits until the operator returns the handset 2 and goes on-hook (decisions 117 and 11).
8 NO loop).

When the connection with the destination is completed and the result of decision 117 becomes YES, the flow shifts to decision 109 to wait for the operator's call to end and the handset to go on-hook, and then to execute the subsequent processing. If the result of decision 118 is YES, process immediately
Move to 111.

Further, the operator inputs the registration key 5 to make a decision.
When the result in step 102 is YES, the CPU 11 starts the clock of the timer for which the fixed time is set (process 120), and monitors that the ten key 3 is operated and input until the timer expires. (ON loop of judgments 121 and 122).

Then, when the operator operates the ten key 3 to input, for example, a key assigned to him / her, the judgment 12
The result of 1 is YES, and the CPU 11 places the ten key redial area TKr corresponding to the key input at that time in the area
The destination telephone number stored in the redial number area ARr is registered (step 123).

For example, when the key "1" of the numeric keypad 3 is operated and input at this time, the destination telephone number stored in the redial number area ARr is stored in the redial 1 area RR1 (see FIG. 3).

Then, it instructs the operation display section 15 to output a registration completion tone (step 124), causes the speaker 8 to output a prescribed registration completion tone, and proceeds to step 110.

If the time is up before the operator operates the numeric keypad 3 and the result of determination 122 is YES, the CPU 1
Step 1 instructs the operation display section 15 to output a time-up tone (step 126), and causes the speaker 8 to output a specified time-up tone (error tone).
Move to

Further, when the operator turns on the redial key 4 and the result of the judgment 103 becomes YES, the CPU 11 starts counting a timer for which a fixed time is set (process 130) and waits until the timer expires. During this time, it is monitored that the ten key 3 is operated and input (NO loop of determinations 131 and 132).

When the operator operates and inputs a key assigned to the user from the ten keys 3, for example, the result of the determination 131 is YES, and the CPU 11 stores the key in the ten key redial area TKr corresponding to the key input at that time. Check whether any phone number is registered (decision 13
3).

If the result of the determination 133 is YES, the telephone number stored in that area is read out and stored in the telephone number temporary registration area (process 134), and the process proceeds to process 116 to perform the process of transmitting the selection signal.

For example, when the key "1" of the ten key 3 is operated and input at this time, the telephone number stored in the redial 1 area RR1 is stored in the telephone number temporary registration area, and a call is made.

If no telephone number is registered in the ten-key redial area TKr corresponding to the key input at that time, the result of determination 133 is NO, and in this case, the processing 134 is not performed. Then, the process proceeds to 116.
In this case, since a valid telephone number is not stored in the telephone number temporary registration area, the selection signal is not output in the process 116.

If the time is up before the operator operates the numeric keypad 3 and the result of the determination 132 is YES, the CPU 1
1 reads out the telephone number stored in the redial number area ARr, stores the telephone number in the telephone number temporary registration area (processing 135), and proceeds to processing 116.

Therefore, when the operator picks up the telephone handset 2 and inputs a telephone number, the destination of the telephone number is called, and when the destination answers and completes the connection, the call operation is interrupted without the destination answering. Sometimes
The telephone number of the destination called at that time is stored in the redial number area ARr.

Then, when the operator returns the handset 2, picks up the handset 2 again, turns on the registration key 5, and subsequently operates a desired key of the numeric keypad 3, the key operated at that time in the numeric keypad redial area TKr The telephone number stored in the redial number area ARr is registered in the area corresponding to.

In this way, a plurality of telephone numbers are registered in the ten-key redial area TKr in a state where they are assigned to the respective keys of the ten-keys 3.

Next, when the operator picks up the handset 2 and turns on the redial key 4, and subsequently operates a desired key on the numeric keypad 3, the destination of the telephone number registered in the numeric keypad redial area TKr corresponding to the key is issued. Called.

If there is no input from the numeric keypad 3 between the time when the redial key 4 is turned on and the time when a certain period elapses,
The destination of the telephone number stored in the redial number area ARr at that time is called.

Thus, for example, when a single telephone is shared by a plurality of persons, if the keys of the numeric keypad 3 which can be used at the time of redialing are assigned to the respective operators, each operator can appropriately use the redial function of the telephone. Can be.

As described above, in the present embodiment, when a plurality of persons share one telephone, each operator can appropriately use the redial function of the telephone.

Further, since a plurality of re-call destinations can be registered, it is very convenient when a plurality of destinations are called alternately.

Also, each operator can specify his or her recall destination by operating the redial key and the ten keys assigned to him, for example, displaying a list of telephone numbers that have been called in the past, This eliminates the need for a display unit required for a conventional device for designating a target recall destination from the list display, thereby reducing the cost of the device.

In the above-described embodiment, the present invention is applied to a telephone. However, the present invention can be similarly applied to devices other than those using a public telephone line network as a transmission line, such as a facsimile device.

[Effects] As described above, according to the present invention, in a recalling method of a communication device using a public telephone line as a transmission line and provided with a selection signal transmitting means, a telephone number immediately before calling is stored. Recalling number storage means, numeric keypad recalling number storage means for storing a recalling number corresponding to each key of the numeric keypad, and recalling number stored in the recalling number storage means or the numeric keypad recalling storage means. Recalling means for calling a call number, recall operation input means for commanding a recall operation, and registration operation input for commanding registration of a recall number in the ten-key recall number storage means. The registration operation input means is operated after the call is made, and the re-call number storage means is stored in the ten-key recall number storage means corresponding to the ten-key input subsequently. When the recalling operation input means is operated and the numeric keypad is subsequently operated, the recalling call stored in the numeric keypad recalling number storage means corresponding to the operated numeric keypad is registered. The number is output to the re-calling means and the re-calling operation is performed. If the numeric keypad is not operated, the re-calling number stored in the re-calling number storage means is output to the re-calling means and the re-calling operation is performed. , A number of re-call destinations can be registered on the numeric keypad, and a plurality of registered re-call destinations can be easily selected by a desired key operation of the numeric keypad, and the re-call operation can be performed. The effect that the operability is remarkably improved is obtained.

Also, for example, when one communication device is shared by a plurality of users, by assigning each key of the numeric keypad to each user, each user can make a call to the telephone number which he / she has just operated at the time of recall. Since it is possible, it is very convenient, and the effect that the handling of the re-call operation when the communication device is shared by a plurality of users is remarkably improved.
