Abstract

PROBLEM TO BE SOLVED: To make a phone call even to a telephone set whose dialing is restricted by making a 3-party speech via a telephone set capable of dialing in the case of making a phone call to a destination to which a portable telephone terminal or the like cannot make dialing. SOLUTION: Whether or not an exclusive key 1d to send a telephone number of a PHS master set 4 registered by a PHS terminal 1 is discriminated and when telephone number is not inputted, the speech between the PHS terminal 1 and the PHS master set 4 is made. When a telephone number is inputted, the PHS master set 4 holds the connection to the PHS terminal 1 and dials the telephone number by the inputted key, tries to make connection to a destination 5 of the telephone number whose dialing is restricted and desired by the user of the PHS terminal 1 so as to discriminate whether or not the connection to the destination 5 can be connected. When the connection can not be made, calling of the telephone set whose dialing is suspended and a hook signal is sent, the holding of the PHS terminal 1 is released and the three-party speech is not executed. When the connection is successful, the three-party speech among the user of the PHS terminal 1, the destination 5 and the master set 4 is started.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of making a call to a restricted telephone number in communication such as a wired (general) telephone or a mobile telephone.

[0002]

2. Description of the Related Art Recently, various communication systems have been developed and put into practical use due to the development of mobile communication technology. In addition, digital communication in consideration of information communication is actively performed.

Specifically, a PDC based on the "digital car telephone system standard" shown in RCR STD-27, which is the standard of the Radio System Development Center.
(Personal Digital Cellular Telecommunication Syst
em) and PHS (Person) based on the "2nd generation cordless telephone system standard" shown in RCR STD-28.
al Handy / phone System) is still in existence.

As a result, the terminal can communicate freely anywhere within the service area of the base station that communicates with the terminal that is a mobile station, which is very convenient.

[0005]

Problems to be Solved by the Invention Here, PDC, PH
Each mobile such as S has its own charge system for communication. Also, the charge system is different from that of regular phones. Naturally, PD of mobile phone that can perform mobile communication
Currently, the charges for C and PHS are somewhat higher.

For this reason, the PDC-PHS and PHS-international telephones cannot be used at present because their fee systems are not matched. Also, various services could not be used due to problems such as the burden of fees. Various services are, for example, toll-free (0120 call), dial Q2 (0990 call), number guide (10
4) etc.

That is, even if the service can be used on a general telephone, the mobile station cannot use the service because the calling position and the usage charge for the movement are different. This is to prevent the receiving side from being disadvantaged and the communication service provider from being disadvantaged.

Therefore, at present, it is not possible to perform communication from a mobile terminal to various services with a specific number or to other mobile communication systems. Further, at present, it is not possible to use the dial Q2 service for public telephones or the like, and the free dial service for some public telephones.

[0009]

According to the present invention, a telephone terminal unit for making a telephone call is communicatively connected by a predetermined first process of the telephone terminal unit and is performed subsequent to the predetermined first process. A telephone system comprising: a telephone device unit for dialing a telephone number of a desired destination set in the second processing; and connecting the telephone terminal unit and the desired destination via the telephone device unit. Is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, before describing the present invention in detail, a telecommunications carrier (for example, Nippon Telegraph and Telephone Corporation: NT)
The "three-way calling service" provided by T) will be described.

When making a telephone call with three parties, any one of the telephone parties can make a contract with a telecommunications carrier. This will be described with reference to FIG. The operation description here shows the service of NTT corporation.

First, it is assumed that the caller A has a three-party call contract. In FIG. 5A, the caller A makes a call and first normally communicates with the caller B. And during that time, caller C
In order to establish a communication connection with the caller A, the caller A hooks the telephone being used (presses a hook switch or operates a key equivalent thereto), and then dials the telephone number of the caller C. At that time, the caller B is notified of the hold sound.

When hooking is performed again after the communication connection with the caller C is made, the caller A releases the hold of the caller B while keeping the communication connection with the caller C, and a three-party call state in which three-way call is possible Becomes At this time, due to the principle that the caller is charged for the caller, between the caller A and the caller B and the caller A-
Since the caller A is making a call to any of the callers C, the caller A is burdened.

Next, another three-way call will be described with reference to FIG. Similarly, it is assumed that the caller A has a three-way call contract. Caller B originates and first normally communicates with caller A. During that time, in order to establish a communication connection with the caller C, the caller A hooks the telephone being used (presses a hook switch or operates a key equivalent thereto), and then the caller C Dial the phone number of. At that time, the caller B is notified of the hold sound.

When the user hooks again after the communication connection with the caller C is made, the caller A releases the hold of the caller B while keeping the communication connection with the caller C, and the caller A is in a three-party call state. Becomes At this time, due to the principle that the caller is charged for the caller, the caller B between the caller A and the caller B is charged.
However, since the caller A makes a call between the caller A and the caller C, the caller B and the caller A are charged respectively.

Therefore, by making a contract with the communication carrier in this way, three-way calling is now possible.

Next, an embodiment of the present invention is shown in FIG.
In addition, PHS will be described as an example.

The PHS terminal (slave unit) 1 comprises a microphone 1a, a speaker 1b, a numeric keypad 1c for inputting, and a dedicated key 1d for automatically dialing a registered master unit. Base station 2
Performs wireless transmission / reception communication with the PHS terminal 1 when the PHS terminal 1 is located within the service area 2a. The exchange 3 is connected by a line to a base station, another exchange, a subscriber telephone such as a home telephone, and a contract telephone providing a service.

The PHS base unit 4 is placed in the home of the user of the PHS terminal 1, is connected to the exchange 3 by a line, and is capable of three-way calling. This PHS master device 4 has the following configuration. A means 4a for discriminating whether or not the three-party call mode, a means 4b for hooking a line on the PHS terminal side that has received a call based on the discrimination result, and an output of the hook means 3b for holding the PHS terminal 1 on the public line side. , Detecting that the telephone number is read from the memory means 4c storing the dial input by the PHS terminal 1 in the setting of the three-way call and the dial means 4d for dialing the destination 5 and the line connection with the destination 5 are made. The PHS master unit 3 has a configuration in which the hooking unit 3b is operated again based on the detecting unit 4e that performs the operation and the result of the detecting unit 3e to release the hold on the public line side.

That is, the user of the PHS terminal 1 dials the registered PHS master unit 4 directly or uses the dedicated key 1d.
By operating and dialing, the connection with the PHS master device 4 can be established. Then, when the telephone number of the other party is continuously input, the PHS master device 4 holds the PHS terminal 1 and dials the telephone number of the other party 5. After that, PHS base unit 4
When the connection with the other party 5 is confirmed, the hold with the PHS terminal 1 is released, and a three-way call is made. Here, since there is no speaker in the PHS master device 4, it seems that the PHS terminal 1 and the other party 5 are connected.

In other words, when the user wants to call a telephone number for a service or the like that is subject to the above-mentioned transmission restrictions from the outside, in the conventional case, a notification that the base station cannot make a call by directly dialing (for example, , Poo Poo Poo, etc. was announced by busy tone), and the user disconnected the line.

Therefore, in the present invention, once the PHS master unit with which the PHS terminal 1 is registered calls 4 and at that time, the PH in the home is sent via the base station whose current position is registered.
The S master unit 4 is contacted. Here, if another PHS terminal registered in the base unit 4 is making a call using the base unit, the PHS terminal 1 is notified as busy,
I can't make a call, so I need to call again.

Then, after the PHS terminal 1 and the base unit 4 have started communication (or following the base unit number (home number)), the user inputs a telephone number on which transmission control is applied. Then, the master unit 4 which receives the dial tone signal (DTMF signal) tries to use the three-party call service contracted with the telecommunications carrier in advance, sends the hook signal, holds the PHS terminal 1, and cancels the call. The other party's telephone number is transmitted, the hook signal is transmitted again in response to the other party, and a three-way call is made. This is because when the master unit 4 confirms the connection with the partner 5, the PHS terminal 1 is released from the hold and a three-way call is made.

If the other party is using the PHS,
The caller (user) of the terminal 1 is informed of the busy state.

[0025] With this, it is possible to make a call even though the call control is applied.

Further, the present invention will be specifically described with reference to the flowchart of FIG.

First, the PHS registered by the PHS terminal 1
It is determined whether the dedicated key 1d for automatically transmitting the telephone number of the parent device 4 has been operated, or whether the telephone number of the parent device 4 has been operated to be input to the PHS terminal 1. This step S1 is repeated until it is determined. After the determination, the process of connecting the PHS terminal 1 and the base unit 4 is performed.

Next, in step S2, if the telephone number is not input by key input within the predetermined time, the PHS terminal 1 and the PHS base unit 4 communicate as usual. That is, the three-way call has not been made (step S9). Then, when there is an input, the PHS base unit 4 transmits a hook signal, suspends the connection with the PHS terminal 1 (step S3), and dials the telephone number by the input key (step S4). The user of No. 1 tries to connect to the other party 5 of the telephone number of the call regulation (regulation that the number cannot be called) desired by the user. The so-called three-way calling service is used.

Then, in step S5, the other party 5
It is determined whether or not the connection with can be made. If the connection with the other party 5 is not possible, that is, if the other party 5 is using the restricted telephone or is not near the called telephone, the call restriction telephone is called. After canceling the call, a hook signal is transmitted, the hold of the PHS terminal 1 is released, the connection between the PHS terminal and the base unit is automatically disconnected by the base unit 4, or the user of the PHS terminal 1 does not answer the call. The user may be informed that the three-way call has not been made by disconnecting the line (step S8) upon receiving the notification of (step S8).

On the other hand, when the connection with the partner 5 is established, the PHS terminal 1 is released from the hold (step S6), and P
A three-party call is started between the user of the HS terminal 1, the other party 5, and the parent device 4. At this time, since the base unit is merely used for making a three-way call and there is no speaker, the PHS
The user of the terminal 1 and the other party 5 are in the normal communication (step S7).

Further, as another implementation, since it is possible to use a call originating from a telephone having a call originating regulation such as a portable telephone, the inconvenience that the call originating regulation is applied to any other party's telephone may occur. There is no. However, this does not apply to three-way calling services that have their own outgoing restrictions.

Further, the PHS master unit of the present invention may be a general telephone having the control of the present invention, and the present invention is not particularly limited to the PHS master unit. In other words, by making a call from a call-restricted phone to a telephone having the features of the present invention, a three-way call is made, and telephone communication can be carried out like a phone without call-restriction in practice.

FIG. 4 is a block diagram of another embodiment of the PHS master unit 4. This is actually possible by adding these circuit blocks to the block diagram of the PHS master device 4 shown in FIG.

First, the incoming signal is input to the control unit 4f, and the identification number of the terminal that originated or the personal identification number when it originated is extracted from the signal and input to one end of the ID discrimination unit 4h. On the other hand, by the control of the control unit 4f, the identification number or the personal identification number stored in advance in the memory unit 4g is input to the other end of the ID determination unit 4h. Then, the ID discrimination unit 4h outputs a signal that enables each unit to operate when the two inputs match. Thereby, it is possible to restrict the use of the three-way calling service when the identification number and the personal identification number are different.

[0035]

As described above, according to the present invention, when a call is made to a partner who cannot make a call from a portable telephone terminal or the like, a three-way call is made via the telephone of the present invention capable of making a call. You can also call.

Further, according to the present invention, since the dedicated key for automatically dialing the parent telephone is provided in the terminal, the telephone number is automatically inputted by inputting the telephone number to the other party who cannot make a call after the operation of the dedicated key. You can call

Further, by registering the ID number of the terminal or the personal identification number at the time of use in the master telephone, it is possible to prevent others from using the three-party call mode without permission.
