The present invention relates to a one-phone service providing system and a method thereof, and more particularly, in a one-phone service providing system, an exchange transmits a wired incoming signal including a one-phone terminal number to a wireless access point in a caller ID area. The wireless access point extracts the one-phone terminal number from the wired incoming call and links the wired incoming call only to the corresponding one-phone terminal, so that the wired incoming call can be linked only to the one-phone terminal of the receiver to which the caller wants to make a call. A provisioning system and method thereof are provided.

Recently, in order to reduce the burden of the mobile communication service fee imposed on the user and to make full use of the existing wired communication network, one-phone service using Bluetooth technology has been developed and actually implemented in a general home or office.

Bluetooth is a technical specification for mobile phones, portable PCs, network access points, and other peripherals and wireless connections (2.4GHz ISM Open Band) within short range (10m to 100m), due to its small size, low cost and low power consumption. This technology is in the spotlight as a wireless communication network. Bluetooth adopts a wireless LAN transmission method using the 2.4GHz band of ISM (Industrial, Scientific, Medical) band. In addition, the band has a common 80MHz wide frequency all over the world, and anyone can use it for free without permission.

One-phone service enables the mobile communication terminal to use both a mobile communication network and a wired communication network using a mobile communication terminal equipped with such a Bluetooth module. For example, by installing a Bluetooth access point (AP) in a home where a one-phone service is provided, when a mobile communication terminal is located in a Bluetooth area provided by the Bluetooth AP, a wired telephone can be received through the Bluetooth AP. If the mobile communication terminal is not located in the Bluetooth area, the mobile communication service can be provided. In this case, one mobile communication terminal can replace a landline telephone at home, and mobile communication services can be provided from the outside, thereby ensuring mobility and achieving a practical and economical effect.

However, while many mobile communication terminals receive one-phone service through one Bluetooth AP, in most cases, since there is only one wired telephone line received by the Bluetooth AP, it is transmitted for a call with a specific mobile terminal user. Wired telephones are transmitted to all mobile communication terminals located in the Bluetooth region of the Bluetooth AP, causing inconvenience. As a result, the concept of one-person ownership of the mobile communication terminal has been lost, and many shortcomings such as invasion of privacy and waste of time due to reception of invalid telephones have been steadily raised.

Accordingly, even if the caller calls the one-phone terminal located in the one-phone service area, the phone does not go to all the one-phone terminals located in the one-phone service area, but the one-phone service system allows the caller to make a call only to the one-phone terminal to which the caller wants to talk. Development is required.

The present invention has been made to improve the prior art as described above, the exchange of the one-phone service providing system includes the number of the one-phone terminal that the caller wants to call in the caller ID area of the landline incoming call to the wireless access point By transmitting and receiving the wireless access point, the wired incoming call is linked only to the one-phone terminal corresponding to the one-phone terminal number in the caller ID area, so that the caller can link the wired incoming call only to the one-phone terminal of the called party. An object of the present invention is to provide a one-phone service providing system and method.

In addition, when the wireless access point initiates wireless communication with the one-phone terminal, the present invention receives the one-phone terminal number information from the one-phone terminal and records it in a database, whereby the caller receives the wired incoming call received from the switchboard. An object of the present invention is to provide a one-phone service providing system and method for implementing a wireless access point that can be transmitted only to a one-phone terminal.

In addition, when the wired telephone channel assigned to the wireless access point is busy by a specific one-phone terminal, the present invention releases the wired call forwarding of one or more other one-phone terminals located in the wireless area of the wireless access point to switch to the mobile communication mode. And resuming the wired call forwarding of the released one-phone terminal when the call is terminated, so that all one-phone terminals can always remain available regardless of whether or not a specific one-phone terminal uses a wired telephone channel. An object of the present invention is to provide a service providing system and method.

In order to achieve the above object and solve the problems of the prior art, the one-phone service providing system of the present invention extracts a wired called number corresponding to the one-phone terminal number of the outgoing signal received from a predetermined calling terminal from a predetermined database, the one-phone A switch that generates a wired incoming call whose terminal number is included in a caller ID area and transmits the wired incoming call to a wireless access point corresponding to the landline called number, and performs wireless communication with one or more one-phone terminals, and receives the received wired And a wireless access point for extracting a one-phone terminal number from an incoming call and linking the wired incoming signal to a one-phone terminal corresponding to the extracted wired called number, wherein the one-phone terminal receives the wired incoming signal and displays a predetermined display means. Characterized in that to display the calling number.

In addition, the one-phone service providing method of the present invention, the exchange receives a call from a predetermined originating terminal and extracts a wired called number corresponding to the one-phone terminal number of the outgoing call from a predetermined database, the exchange is the wired 2, which sets a called number as a received number, generates a wired incoming signal including a caller ID in which the one-phone terminal number is located in preference to the calling number of the calling terminal, and transmits it to a wireless access point corresponding to the called line. In step 3, the wireless access point receives the wired incoming call, and extracts the one-phone terminal number from the caller ID area of the wired incoming call. The wireless access point performs wireless communication with the one-phone terminal corresponding to the one-phone terminal number. Performing the step 4 of linking the wired incoming call, and the one-phone end Group includes a fifth step of displaying the calling party number extracted from the linked wire incoming call caller ID area.

The wireless communication described herein refers to Bluetooth. Wireless LAN (IEEE 802.11a, b, g, etc.), and other concepts that encompass all wireless communication methods over the air. In addition, a wireless access point (AP) is a means for performing the above-described wireless communication, and is a concept including all of a Bluetooth AP, a WLAN AP, a wireless transceiver, and the like.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a diagram showing a network configuration of a one-phone terminal providing system according to an embodiment of the present invention.

The one-phone service providing system according to an exemplary embodiment of the present invention includes a wireless access point 110, a first one-phone terminal 111 to a fourth one-phone terminal 114, an exchange 120, a calling terminal 130, a wired telephone network ( 140, and a mobile communication network 150.

According to an embodiment of the present invention, the user of the calling terminal 130 transmits an outgoing signal to the exchange through the wired telephone network 140 or the mobile communication network 150 for a call with the user of the first one-phone terminal 111. . The calling terminal 130 may be a wired telephone using the wired telephone network 140 or may be a mobile communication terminal using the mobile communication network 150. The calling terminal 130 may include a predetermined communication module such as an internet telephone, a PC, a laptop, a PDA, and the like. It can include all of one terminal.

The exchange reads the call signal received from the calling terminal 130 and recognizes that the terminal to which the call signal is to be transmitted is the first one-phone terminal 110 belonging to the wireless access point 110. When the first one-phone terminal 111 to the second one-phone terminal 114 performs the wired call forwarding to terminate the mobile communication service and initiate wireless communication with the wireless access point 110, the predetermined one mobile communication system ( (Not shown) to start the wireless communication.

As will be appreciated by those skilled in the art, call forwarding means that a user receiving a communication service with a specific communication number through a predetermined communication network can receive a communication service through a communication number other than the communication number. That is, according to the call forwarding service, when a situation change occurs such that communication with a specific communication number cannot be performed, a second communication number that is provided through the communication number is set by setting a second communication number instead of the communication number. You can be provided through the communication number of. The call forwarding service is a service currently provided by all communication service providers, and some mobile communication terminals are implemented to receive such call forwarding service as one of the terminal's own functions. The call forwarding service records a second communication number corresponding to the specific number in a user information database attached to a communication exchange, etc., and enters the specific number when a call forwarding service trigger signal is received from a user or the like. The call can be implemented in such a way as to forward the call to the second communication number.

In addition, the mobile communication system notifies the exchange 120 of the fact that the wireless communication start corresponding to the call forwarding.

When the first one-phone terminal 111 is initiated wireless communication with the wireless access point 110, the switch 120 is a database of the wired called number corresponding to the one-phone terminal number included in the outgoing signal received from the originating terminal 130 Extracted from (not shown).

For example, when the one-phone terminal 111 number is "011-9085-7821", the exchange 120 extracts a "wireline call forwarding number" 031-785-6770 "correspondingly from the database. The one-phone terminal number is a mobile communication number of the first one-phone terminal 111, and the landline called number is a wired telephone number assigned to the wireless access point 110. For the extraction operation, the exchange 120 may record and maintain a wired called number and one-phone terminal number previously assigned to one or more wireless access points and their respective one-phone terminals in a database.

The exchanger 120 generates a wired incoming signal in which the extracted wired called number is set to a received number. In addition, the exchange 120 inserts the one-phone terminal number of the first one-phone terminal 111 in the caller ID area of the landline incoming call. The exchange 120 may insert the one-phone terminal number into the caller ID region so that the one-phone terminal number is positioned in preference to the calling number of the calling terminal 130 already included in the caller ID region. This will be described in detail with reference to FIG. 2.

2 is a diagram illustrating a structure of a wired incoming call generated by an exchange according to an embodiment of the present invention.

The wired incoming signal 200 generated by the switch 120 may be largely divided into a ring signal region 210 and a caller ID region 220. The exchange 120 may record the wired called number of the wireless access point 110, which is the called terminal to which the wired incoming signal 200 should be transmitted, in the ring signal area 210. In addition, the caller ID area 220 may record the one-phone terminal number of the first one-phone terminal 111 as well as the calling number of the calling terminal 130.

For example, as illustrated in FIG. 2, the switch 120 records the extracted wired called number “031-785-6770” in the ring signal area 210 and the caller ID area 220 of the calling terminal. The wired incoming call 200 may be generated so that the first one-phone terminal number 221 is located in preference to the calling number 222.

Recording the one-phone terminal number in preference to the calling number as described above means that when the first one-phone terminal 111 is linked with the landline call, the one-phone terminal number is displayed on the display means (LCD) of the first one-phone terminal 111. This is to ensure that the calling number is displayed. This will be described in detail later with reference to FIG. 4.

In FIG. 1, the switch 120 transmits the generated wired incoming call 200 to the wireless access point 110 through the wired telephone network 140. The wired telephone network 140 may include not only an existing wired telephone network of a public switched telephone network (PSTN) but also an internet telephone (VoIP) network and the like, and may include all wired telephone networks that can be developed and used in the future. have.

The wireless access point 110 receives a wired incoming signal from the exchange 120 through the wired telephone network 140. The wireless access point 110 extracts the one-phone terminal number from the caller ID area of the received wired incoming call, and transmits the one-phone terminal to the one-phone terminal corresponding to the extracted one-phone terminal number among one or more one-phone terminals performing wireless communication. Link

The configuration and operation of the wireless access point 110 will be described in detail with reference to FIG. 3.

3 is a block diagram illustrating a configuration of a wireless access point according to an embodiment of the present invention.

According to FIG. 3, the wireless access point 300 according to an embodiment of the present invention includes a wired interface unit 310, a called number extracting unit 320, a one-phone database unit 330, a call transmission control unit 340, and And a wireless communication module 350.

The wired interface unit 310 receives a wired incoming call from the exchange 302 through the wired telephone network 301. The wired interface unit 310 may include a predetermined connector for cable connection with the wired telephone network 301.

The called number extracting unit 320 extracts the one-phone terminal number from the caller ID area of the received wired incoming call. According to the exemplary embodiment of the present invention, the called number extracting unit 320 recognizes the recorded number as the one-phone terminal number, which is given priority to the front of two numbers (called number and calling number) recorded in the caller ID area. Can be extracted.

The wireless communication module 350 performs wireless communication with the first one-phone terminal 361 to the fourth one-phone terminal 364 or the wireless telephone dedicated terminal 370 through the wireless communication network 303.

The call transmission control unit 340 determines whether the one-phone terminal corresponding to the extracted one-phone terminal number is performing wireless communication with the wireless communication module 350. As a result of the determination, when the one-phone terminal is performing wireless communication with the wireless communication module 350, the call transmission control unit 340 links the wired incoming call with the one-phone terminal. For example, when the one-phone terminal number is a number corresponding to the first one-phone terminal 361, the call transmission controller 340 may link the wired incoming call only to the first one-phone terminal 361. Accordingly, since the wired incoming call is not linked to the second one-phone terminal 362 to the fourth one-phone terminal 364 or the wireless telephone dedicated terminal 370, the second one-phone terminal 362 users to the fourth one-phone terminal 364 or The user of the wireless phone dedicated terminal 370 does not need to make unnecessary calls according to the wired incoming call.

If the first one-phone terminal does not perform wireless communication with the wireless communication module 350, the call transmission control unit 340 may be a second one-phone terminal 362 and a third one-phone terminal capable of wirelessly communicating the wired incoming call. 363, the fourth one-phone terminal 364, or a wireless telephone dedicated terminal 370 may be linked.

The one-phone database unit 330 records the one-phone terminal information respectively received from the first one-phone terminal 361 to the fourth one-phone terminal 364 through the wireless communication module 350. The one-phone terminal information includes the one-phone terminal number of each one-phone terminal.

When the wired incoming call is linked with the first one-phone terminal 361, the call transmission controller 340 wirelessly communicates with the wireless communication module 350 by another one-phone terminal in which the one-phone terminal information is recorded in the one-phone database unit 330. Determine if you are performing. That is, it is determined whether the second one-phone terminal 362, the third one-phone terminal 363, and the fourth one-phone terminal 364 are located in the wireless region of the wireless access point 300 and are switched to the wired line.

As a result of the determination, when the second one-phone terminal 362 and the third one-phone terminal 363 are performing wireless communication with the wireless communication module 350, the call transmission control unit 340 is the second one-phone terminal 362 and The third one-phone terminal 363 controls to release the wired call forwarding. Further, the switch 302 is notified of the wired call forwarding fact of the second one-phone terminal 362 and the third one-phone terminal 363, and the switch 302 transmits an outgoing signal to the one-phone terminal through the mobile communication network. Control to transmit.

The second one-phone terminal 362 and the third one-phone terminal 363 release the wired call forwarding, so that even if the wired line assigned to the wireless access point 300 is in a busy state by the first one-phone terminal 361, the mobile phone is moved. It is possible to receive an incoming call from a predetermined caller through the communication network.

In addition, when the link between the first one-phone terminal 361 and the wired incoming call ends, the call transmission control unit 340 resumes the wired call forwarding of the second one-phone terminal 362 and the third one-phone terminal 363 again. To control. Also, the switch 302 is notified to the switch 302 of the wired call forwarding of the one-phone terminals, so that the switch 302 converts an outgoing signal sent to the second one-phone terminal 362 and the third one-phone terminal 363 to a wired incoming signal. Allows transmission to the wireless access point 300.

The originating number included in the caller ID region of the wired incoming call may be displayed in the one-phone terminal to which the landline incoming call is linked through the wireless access point 300. The display operation will be described in detail with reference to FIG. 4.

4 is a diagram illustrating a structure in which a caller ID of a wired incoming call is displayed on a one-phone terminal according to one embodiment of the present invention.

The one-phone terminal to which the wired incoming call is linked through the wireless access point may display the calling number of the calling terminal included in the caller ID area of the wired incoming call. In the caller ID area of the landline incoming call, an exchange is prioritized by the one-phone terminal number, and the calling number is next recorded.

A display means (LCD) of a typical one-phone terminal (mobile communication terminal) is provided with twelve digit areas 411 to 422 as an area for displaying the calling number of the caller ID. The one-phone terminal extracts the calling number recorded in the caller ID area in order from digit 1 and displays the twelfth digit area 422. The first digit 1 displayed in the twelfth digit area 422 may be a shift method displayed in the eleventh digit area 421 as soon as the second digit 2 is displayed in the twelfth digit area 422. have. This display sequence can be applied to display the calling number on the display means.

The caller ID area of the wired incoming call according to the present invention includes not only the calling number but also the one-phone terminal number. However, since the one-phone terminal number is located in preference to the calling number, only the calling number may be displayed on the display means of the one-phone terminal when the display sequence is applied.

For example, when the one-phone terminal number "011-9085-7821" and the calling number "02-511-4210" are recorded in order in the caller ID area, the one-phone terminal is the one-phone terminal number "011-9085-". 7821 "is displayed from the twelfth digit area 422 in digit order. After all of " 011-9085-7821 " are displayed in each digit area, the one-phone terminal starts to display the caller number " 02-511-4210 ". As a result, when both "02-511-4210" are displayed, the "011-9085-7821" is pushed out of the digit area and is not displayed.

Accordingly, only the calling number included in the caller ID area may be displayed on the display means of the one-phone terminal. Recognizing "02" as "0002" and recognizing "511" as 0511 ", the operation of distinguishing the area code or the station number of each digit area is implemented by a predetermined program of the one-phone terminal and can be variously performed by those skilled in the art. For example, according to an implementation method, a special character (eg, Enter) may be displayed between the one-phone terminal number (called number) and the calling party number.
