1 is a configuration diagram of an embodiment of a wireless public telephone system using Bluetooth according to the present invention.

As shown in FIG. 1, the present invention includes a terminal 11 with a Bluetooth function, an access point 12 for a public network, a communication network (xDSL) 13, a local exchange 14, and an intelligent network 15. It is provided.

In the wireless public telephone system of the present invention, in order for a customer to use the proposed public telephone system using Bluetooth, a terminal 11 such as a cellular phone, a PDA, a wireless telephone, a laptop, and the like having a Bluetooth voice call function should be provided. .

At this time, the customer can set two types of automatic call mode and manual call mode for outgoing calls. If the automatic call mode is set, the call is sent using the Bluetooth wireless public telephone system in the Bluetooth area and the mobile phone service is sent outside the Bluetooth area. On the other hand, when the manual call mode is set, the mobile phone may be forced to be sent only to the mobile phone service or the Bluetooth public telephone service. In such a case, if the mobile phone service is set to transmit, even if the Bluetooth area, only the mobile phone is sent, and if only the Bluetooth public phone system is set to send only the Bluetooth area regardless of whether or not to send only to the Bluetooth public phone system. In this case, the call is not made outside the Bluetooth area.

On the other hand, in the case of an incoming call, the user can receive an incoming call through the wireless public telephone system if the user designates it in the Bluetooth area (subscribing to the forwarding service of KT or the mobile phone company). Incoming calls can also be received. That is, when a mobile phone call occurs during a Bluetooth wireless public phone call, the mobile phone call may be temporarily suspended and a mobile call incoming signal may be received. In addition, when an incoming call occurs through a Bluetooth wireless public phone during a mobile phone call, the mobile phone call may be temporarily suspended and a wireless public phone incoming call may be received.

The public network access point 12 is provided by a public telephone service provider and installs several Bluetooth modules in one device to solve the disadvantages of the existing public telephones. In other words, the number of voice call lines that can be used at the same time is determined according to the number of Bluetooth modules installed as a connection device that allows Bluetooth to be connected between the Bluetooth terminal and the communication network 13. For example, if there is one Bluetooth module, three people can talk simultaneously. If there are N Bluetooth modules, N × 3 people can talk simultaneously. Accordingly, the frequency of use of the public payphones has been considerably reduced compared to the mobile phone service from the user's point of view. The use of Bluetooth provides users with a convenience similar to that of a mobile phone and uses a wired network. It is expected to increase the frequency of use by reducing the usage fee. In addition, operators can significantly reduce the cost of installation and maintenance.

However, since the communication range of Bluetooth is about 10M and does not roam with other communication means, using the Bluetooth function of the cellular phone and the AP of the wireless aerial system, the call is terminated when the Bluetooth area is out of the Bluetooth area. Therefore, the Bluetooth wireless public telephone call must not leave the Bluetooth area.

In order to secure multiple lines between the local exchange 14 and the access point 12, by using the xDSL-type digital line 13 instead of the existing analog line, several people can simultaneously call even though one line is physically used. You can make it a line that you can.

The local exchange 14 is a switch in which a line for VoDSL (Voice of Digital Subscriber Line) is installed and functions to connect the public network access point 12 and the intelligent network 15 as an authentication system.

The intelligent network 15 is an authentication system for authenticating a KT card, a lifetime telephone number holder, and the like, and authenticates a user of a wireless public telephone network with a Bluetooth function, thereby providing authentication / unauthenticated information through an access point 12 through a local exchange 14. To pass.

2 is a flowchart illustrating an outgoing call method of a Bluetooth wireless public telephone system according to the present invention.

The outgoing call method according to the present invention includes a pre / postpaid call method using a KT card and a call method using a lifetime telephone number. In the case of using a KT card, the user's terminal used in the present invention enters and uses the information necessary for card authentication and billing, and when using a lifetime telephone number, the user's terminal requires a lifetime telephone number and authentication information. Enter to use.

First, when a user makes a phone call using the terminal 201, the terminal transmits a number required for authentication together with the outgoing telephone number to the access point (202). Thereafter, data necessary for authentication among the information connected to the access point through the Bluetooth wireless connection is transmitted from the access point to the authentication center through the local exchange (203). At this time, the access point transmits data required for card authentication to a local exchange using a digital line (ADSL, VDSL, etc.) without transmitting a complex frequency code (DTMF: Dual Tone MultiFrequency) on a time-consuming analog line. The local exchange receiving the information necessary for authentication transmits the data to the authentication center of the intelligent network using the data network (203).

If it is recognized as originating by a valid user from the card authentication center (204, 205), the local exchange sends a dial tone to the access point. The access point detects the dial tone transmitted from the local exchange and transmits the outgoing telephone number (208), and the user receives a service such as a general public telephone through the terminal.

In the case of the prepayment method by the KT card in performing the above procedure, an inquiry about the current balance at the time of charging is performed through the access point, and a warning sound is given when the balance is insufficient.

3 is a flowchart illustrating an embodiment of an access point in the calling method according to the present invention.

As shown in FIG. 3, the access point continuously searches whether the caller receives the calling number and authentication number (prepaid / postpaid card authentication number, lifetime telephone number, etc.) from the terminal (301), and returns the calling number and authentication number. When the transmission is received, the received authentication number is sent to the authentication center (302), and checks whether the authentication result is received from the authentication center and waits (303). At this time, if the authentication result does not come from the authentication center, the authentication number is sent again after a certain time. If the authentication result is received from the authentication center, depending on whether the result is a valid user (304), if the user is a valid user, the calling number is sent to the exchange (305). (306).

4 is a flowchart illustrating an embodiment of a terminal in a telephone call process according to the present invention.

As shown in Figure 4, when the user enters the calling number in the terminal to start the call by pressing the call button (401), the processor of the terminal determines whether the user can use the Bluetooth wireless public telephone (402), the determination result If it is not a Bluetooth user, a normal mobile phone call is made (403). If the result of the determination is a Bluetooth user, it is determined whether the current terminal mode is an automatic call mode or a manual call mode (404). As a result of the determination, if the current mode is an automatic call mode, it is determined whether the current user's location is a Bluetooth serviceable area (405). Make a call (408). As a result of the determination, if the current mode is the manual call mode, it is determined whether the current mode of the manual call mode is the mobile phone communication mode or the Bluetooth communication mode (407). In the Bluetooth communication mode, it is determined whether the area where the current user is located is a Bluetooth service area (409). In the case of a Bluetooth area, the call is made by a public telephone using a Bluetooth method (411). ).

5 is a signal flow diagram of an embodiment of an incoming call in a Bluetooth wireless public telephone system according to the present invention.

As shown in FIG. 5, when the terminal enters the Bluetooth service area, the terminal transmits user information (built-in lifetime telephone number or call transfer service mobile number) to the access point (501). The number to be called is transmitted to the communication network (502). Thereafter, the called party exchange registers the incoming call number to the access point's telephone number (503), and upon receiving the incoming call from the calling exchange, transmits the called number (called ID) to the access point together with the incoming call. (504). Next, the access point analyzes the incoming ID received with the incoming call (505), and sends the incoming call to the terminal having the corresponding ID (506) to make the incoming call (507).

Figure 6 is a flow chart of an embodiment of a method of receiving a Bluetooth wireless public telephone system according to the present invention.

In order to receive the incoming call service of the Bluetooth wireless public telephone system, the user must be a lifetime telephone number service user who has a lifetime telephone number stored in a mobile phone or a call transfer service user to a cellular phone.

If the terminal owner moves to the Bluetooth service area (601), and if the terminal receives a lifetime telephone number service (602), the lifetime telephone number embedded in the terminal is automatically transmitted to the access point via Bluetooth (603). On the other hand, if the terminal does not receive a lifetime telephone number service (602), it is determined whether the mobile phone transfer service subscriber (604), the procedure is terminated if the subscriber is not a transfer service, and the terminal number to be transferred if the transfer service subscriber 605 is transmitted to the access point.

The access point that receives the lifetime telephone number or the terminal number to be transferred (606, 608) registers the incoming call transfer to the communication network with the received lifetime telephone number or the terminal number to be transferred to the communication network (607, 609).

When an incoming call occurs (610), the incoming ID (ID) received with the incoming call, that is, the registered lifetime telephone number or terminal number is analyzed (611), and the incoming call is sent to the terminal having the corresponding ID using Bluetooth. Thereby (612), allowing the user to make an incoming call (613).

At this time, when a call is made to a lifetime telephone number or a terminal number to be transferred, the exchange simultaneously transmits a lifetime telephone number or terminal number to be transferred to the access point in the form of Called ID. Here, the Called ID is different from the usual Calling ID indicating the caller's number so that the caller's lifetime number or the terminal number to be transferred is displayed when the caller sends out the lifetime telephone number or the terminal number to be transferred. .

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, in the area that the Bluetooth service from the user of the service, a large number of users can use the public telephone service by using their respective terminals, by embedding the Bluetooth function in the existing mobile phone, Mobile phone users can use the phone without paying expensive mobile phone fees, and can reduce the blind spots by using a short-range wireless network in a non-wireless area. It works.

In addition, from the point of view of the service provider, it can be installed at a lower cost than the existing public telephone network or Citiphone service, and the cost can be reduced in maintenance.
