By the above-described configuration, the present invention provides an individual incoming function to the one-phone terminal at low cost and simple facilities, thereby providing a weak individual incoming function when utilized as a landline telephone and protecting the privacy of the one-phone terminal user. .

Description

System and method for individual incoming call of one-phone terminal in Bluetooth mode {SYSTEM AND METHODE FOR ONE-PHONE'S RECEIVING CALL IN BLUETOOTH MODE}

The present invention relates to an individual incoming system and method of one-phone that supports a mobile communication mode and a wireless telephone using Bluetooth in one terminal. More particularly, the present invention relates to a system and method for individually incoming calls received in Bluetooth mode.

Bluetooth is a technical specification for wireless connectivity (2.4GHz ISM Open Band) within short range (10m to 100m) of small, low cost, low power consumption portable devices such as mobile phones, portable PCs, network access points, and other peripheral devices. It is a technology that is in the spotlight as a local area network.

Bluetooth adopts a wireless LAN transmission method using the 2.4GHz band of ISM (Industrial, Scientific, Medical) band. The 80MHz wide frequency is commonly assigned to this band worldwide, making it free for anyone to use without government approval. This band suppresses mutual interference by limiting the size of the transmission output to 100mW or 1mW so that multiple users can share it. The basis of Bluetooth is packet communication, but both data and voice communication are possible. By connecting two devices one-to-one, one-way data transfer can be up to 721kbps. In Bluetooth, up to eight devices come together to form a single network called a piconet, which allocates the entire capacity as appropriate between devices.

In addition, several independent piconets can be overlapped in the same space, so that they can be applied to places with high density of information processing and communication devices. Other features include transmission error correction, identity verification, passwords and power saving features.

Due to the advantages of the above-mentioned Bluetooth, the leading field of the application of Bluetooth is the application of the mobile phone. Among these applications, there are one-phone (two in one-phone or three in one-phone) which can use mobile communication and wireless telephone using a wired network, and Ericsson, Nokia, etc. have already produced the one-phone terminal. The one phone integrates the CDMA module and the Bluetooth module into one terminal, and the Bluetooth module performs Bluetooth communication with a Bluetooth access point, which is a connection point of an external network such as a PSTN or an XDSL. Therefore, the one-phone user can make a call by making a call using a wired network in the Bluetooth area, thereby making it possible to make a call at a low rate while ensuring its mobility.

1 is a schematic diagram illustrating an entire system for the aforementioned one-phone service.

The one-phone terminal 100 having the CDMA mobile communication and the Bluetooth function can be used as a normal mobile communication terminal outside the Bluetooth area 10, and when entering the Bluetooth area 100, automatically or manually switch to the Bluetooth mode. To perform wireless communication with the Bluetooth access point 200. At this time, the outgoing call of the one-phone terminal 100 is directed to the wired network 30 through the Bluetooth access point 200. The call is transmitted to the called party 60 through the wired network 30 or the mobile telephone network 40 according to the called party's environment. In addition, it is possible to use a variety of additional services using the intelligent network 50 according to the designation of the sender and the called party.

That is, the Bluetooth mode of the one-phone service performs the same operation as using a normal wired network except for performing Bluetooth communication between the Bluetooth access point and the one-phone. Accordingly, the charge of the wired telephone network can be applied.

However, when the one-phone is used as a landline phone within Bluetooth coverage, the individual call function of the mobile communication terminal is limited due to the characteristics of the landline phone. That is, since a plurality of one-phone terminals used in one access point are used as one called number, a call received through one access point must send a ringing tone to all the family members. Incoming functions are greatly limited and privacy problems occur.

Therefore, in order to maximize the combined effect of mobile communication and wired telephone using Bluetooth, the minimum individual incoming function of one phone must be guaranteed even in Bluetooth mode.

The present invention provides a one-phone system and one-phone service method that provides a simple facility and individual incoming call function at a low cost in order to solve the above problems of the prior art.

In more detail, the present invention provides an individual call system and method of one-phone which can bring the effect of reducing call charges on the caller side using the existing CID technology and ensure the privacy of the recipient.

In order to achieve the above object of the present invention, the one-phone individual incoming system according to an aspect of the present invention, CID table that stores the Bluetooth device identifier of the one phone and the corresponding CID information; An incoming signal detection unit for detecting an incoming signal and CID information from a wired communication network and retrieving a Bluetooth device identifier corresponding to the CID information from the CID table; A Bluetooth device detector for searching for a Bluetooth device corresponding to the Bluetooth device identifier transmitted from the incoming signal detector; If the searched Bluetooth device is present in the Bluetooth coverage includes a Bluetooth module control unit for transmitting the individual incoming signal to the corresponding one phone.

The Bluetooth device identifier may include a Bluetooth device address, and the Bluetooth device identifier and CID information of the CID table may be added and updated.

In addition, the individual call method of the one-phone according to an aspect of the present invention, registering the Bluetooth device identifier and the corresponding CID information in the CID table; Detecting an incoming signal and CID information from the wired communication network by the incoming signal detection unit in the Bluetooth access point; Retrieving, by the incoming signal detector, an identifier of a Bluetooth device corresponding to the detected CID information from the CID table; And when there is an identifier of a Bluetooth device corresponding to the CID information, transmitting the individual incoming signal to the Bluetooth device by the Bluetooth access point.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

Now, an individual call method according to an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 2 shows a schematic diagram of a one-phone individual incoming system according to an embodiment of the present invention.

The system of an embodiment of the present invention includes one-phone terminals (100a, 100b, 100c), a Bluetooth access point (200), and a public network (PSTN) 300 that support mobile communication and wireless phones in Bluetooth mode.

Here, the Bluetooth access point connected to the public network includes a CID table 210, an incoming call detection unit 220, a Bluetooth device detection unit 230, and a Bluetooth module control unit 240. Although not shown in FIG. 2, it is obvious to those skilled in the art that the Bluetooth access point 200 includes a Bluetooth module for supporting in-house Bluetooth communication.

The CID table 210 matches and stores the caller ID and the Bluetooth device identifiers of the one-phone terminals 100a, 100b, and 100c. The Bluetooth device identifier includes a Bluetooth device address or a Bluetooth device serial number. The CID table may be registered through separate communication between the one-phone terminal and the Bluetooth access point 200 and may be updated and added. The Bluetooth access point stores the caller's telephone number corresponding to the Bluetooth identifier of the one-phone terminal requesting registration and update in the CID table 210.

The incoming detection unit 220 detects an incoming signal from the public network 300. Since the incoming call signal includes the caller's phone number information, when the incoming call detection unit 220 detects the incoming signal, the CID table 210 is searched to search for the Bluetooth device identifier corresponding to the caller's phone number. If present, the device identifier along with the incoming signal is transmitted to the Bluetooth device detector 230.

The Bluetooth device detector 230 searches for a Bluetooth device performing Bluetooth communication within the coverage of the Bluetooth access point. If the Bluetooth device of the Bluetooth device identifier corresponding to the caller's telephone number is in the connected state as a result of the search, the Bluetooth module controller 240 notifies the Bluetooth device control unit 240 to set the incoming call to the one-phone having the Bluetooth identifier.

3 is a table illustrating an information type stored in the CID table 210 according to an embodiment of the present invention.

3, the Bluetooth device addresses of the one-phone terminals 100a, 100b, and 100c are recorded in the terminal address field in the CID table 210, respectively. The CIDs are recorded in the CID table 210 in correspondence with the Bluetooth device addresses, respectively. The CID may be stored and divided into a general telephone, an extension number, and a mobile terminal telephone number according to its characteristics. The user may input an arbitrary name for the Bluetooth device address.

Although FIG. 3 illustrates a Bluetooth address for identifying one-phone terminals, it will be obvious to those skilled in the art to implement the table using other Bluetooth device identifiers.

4 is a flowchart illustrating the steps of registering an individual incoming service according to an embodiment of the present invention.

When the registration of the individual caller ID of the one-phone terminal is started, the Bluetooth access point searches for the device address of the peripheral one-phone terminal (S20). When the search is completed, one terminal of the found Bluetooth device addresses is selected (S30). Here, the selected terminal can be given a unique name. In step S40, caller information is input for the selected one-phone terminal. The caller information may be prepared by adding the caller's name or information on the caller terminal together with the caller's telephone number. If there is an additional input, additional caller information is input for one terminal, and if there is no further input information, registration of caller information is completed (S50).

5 is a flowchart illustrating a call forwarding flow according to an embodiment of the present invention.

When there is a call request to the landline telephone number to which the one-phone AP is subscribed through the public network 300, the call signal detecting unit 220 detects the call signal (S100). When the incoming signal is detected, the incoming signal detection unit searches for the Bluetooth device address of the one phone in the CID table 210 by using the CID information transmitted together with the incoming signal (S200).

In step 300, the CID table 210 determines whether the Bluetooth device corresponding to the CID of the incoming signal is found, and if the corresponding one phone exists, only the one phone terminal transmits the incoming signal individually (S400). Here, when a plurality of one phones are registered for the same CID, an incoming signal is transmitted to the plurality of one phones.

If the Bluetooth device address corresponding to the CID is not found, the Bluetooth access point transmits an incoming signal to all registered one phones (S500).

In addition, in this case, when the corresponding one-phone terminal which individually transmits the incoming signal is inactive, it is possible to set the incoming signal to all the one-phone terminals.

In an embodiment of the present invention, a conventional Bluetooth access point collects and manages a Bluetooth device address when connecting to Bluetooth devices, and uses CID information provided from a wired telephone service for application to individual calls of one phone. This makes it possible to economically implement an individual incoming system without additional equipment or equipment.

In addition, the individual call system according to the present invention is to provide a function that can automatically switch the mobile phone number of the one phone to the landline telephone number, extension phone number, lifetime telephone number, etc. when the one phone is switched to Bluetooth mode. desirable.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

According to the configuration of the present invention described above, it is possible to remove the restriction of the individual call of the one-phone which can be used simultaneously with the mobile communication telephone and the landline telephone, and to protect the privacy effect. In addition, the configuration of the present invention has a remarkable effect that can configure the individual incoming system without the large additional cost or additional equipment by applying the configuration of the Bluetooth module of the existing Bluetooth access point and CID service.
