Provide the medium.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

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, a customer must have a terminal 11 such as a cellular phone, a PDA, a wireless telephone, and a laptop with a Bluetooth voice call function in order to be able to use the proposed public telephone system using Bluetooth.

In this case, the customer can set two types of automatic call mode and manual call mode for outgoing calls. When set to auto dialing mode, the system uses the Bluetooth wireless public telephone system in the Bluetooth area and the mobile phone service outside the Bluetooth area. When set to the manual call mode, the mobile phone can be forced to be sent only to the mobile phone service or the Bluetooth payphone service. If it is set to send by mobile phone service, even if it is a Bluetooth area, only the mobile phone will be sent. If it is set to send only by Bluetooth public phone system, it will be sent only to the Bluetooth public phone system regardless of whether it is a Bluetooth area or not. 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 phone call may be received. When an incoming call occurs through a Bluetooth wireless public phone during a mobile phone call, the mobile phone call can be temporarily suspended and a wireless public phone incoming call can be received.

Public network access point 12 is provided by a public telephone service provider to install a number of Bluetooth modules in a single device in order to solve the disadvantages of the existing multiple public telephones to allow several people to talk at the same time. 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. If there is one Bluetooth module, three people can talk simultaneously. If there are N Bluetooth modules, N x 3 people can talk simultaneously. Accordingly, the frequency of use of the public payphones has been significantly reduced compared to the mobile phone service from the user's point of view, and the frequency of use has been considerably reduced. It is expected to increase the frequency of use by making it inexpensive. And for operators, the cost of installation and maintenance can be dramatically reduced.

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

In order to secure multiple lines between the local exchange 14 and the access point 12, xDSL-type digital lines 13 are used instead of the existing analog lines, so that multiple people can simultaneously call even though they use a single line. 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 KT card, lifetime telephone number holder, etc., and authenticates the user of the wireless public telephone network of the Bluetooth function to access authentication / authentication information through the local exchange 14 to the access point 12. 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 prepaid calling method using a KT card and a calling 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 the user makes a call using the terminal 201, the terminal transmits the number required for authentication to the access point together with the calling telephone number (202). Data necessary for authentication among the information connected to the access point through the Bluetooth wireless connection is transmitted to the authentication center through the local exchange from the access point (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 (205) by a valid user from the card authentication center, the local exchange sends a dialing 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 using 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.

The access point continuously searches (301) whether the calling number and the authentication number have been sent from the terminal, and if the calling number and the authentication number are sent, sends the received authentication number to the authentication center (302) and authenticates the authentication center. 303 waits to see if a result has been received. At this time, if the authentication result does not come from the authentication center, the authentication number is sent again after a certain time. Upon receiving the authentication result from the authentication center, if the result is a valid user 304, if the user is a valid user, the caller sends the calling number to the exchange (305).

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, 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), and if the result of the determination is not a Bluetooth user, the normal mobile telephone call (403). In operation 404, it is determined whether the call is in the manual call mode. If the current mode is an automatic call mode, it is determined whether the current user's location is a Bluetooth serviceable area (405). If the Bluetooth area is an outgoing call to a public telephone using a Bluetooth method (406). ) On the other hand, if the current mode is a manual call mode, it is determined whether the current mode is a mobile phone communication mode or a Bluetooth communication mode among the manual call modes (407). If it is determined that the area where the current user is located is a Bluetooth service area (409), if the Bluetooth area is dialed by a public telephone by the Bluetooth method (411), if not the Bluetooth area and displays an error message (410) is impossible to send.

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.

When entering the Bluetooth service area, the terminal transmits user information (built-in lifetime telephone number or call transfer service mobile phone number) to the access point (501), and the access point transmits the incoming number of the user information to the communication network ( 502). 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 party exchange, sends the called number (called ID) to the access point together with the incoming call (504). do. The access point analyzes (505) the incoming ID received with the incoming call and sends (506) the incoming call to the terminal having the corresponding ID to allow 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.

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

The access point (606, 608) receiving the lifetime telephone number or the terminal number to call transfer in the above, the incoming call conversion registration (607), the received lifetime telephone number or terminal number to call transfer to the communication network as the telephone number of the access point 609).

When an incoming call is generated (610), the incoming ID (ID) received with the incoming call, that is, the registered lifetime telephone number or the terminal number is analyzed (611), and the incoming call is sent to the terminal having the corresponding ID using Bluetooth (612). By doing so, the user can enable the incoming call (613).

At this time, when a call is made to a lifetime phone number or a terminal number to be transferred, the exchange simultaneously transmits the incoming call signal to the access point and the lifetime telephone number or terminal number to be transferred in the form of Called ID. Called ID here is different from the normal Calling ID which indicates the caller's number so that the caller's lifetime number or 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 apparent 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.
