The present invention relates to an access point and a one-phone service method of a one-phone service system. More particularly, the wireless access point extracts a calling number from a caller ID area of a wired incoming call received from an exchange, and the wireless access point. Wireless linking the wired incoming call only to the one-phone terminal of the user who the caller wants to call by linking the wired incoming call only to the one-phone terminal in which the calling number is registered in the memory of one or more one-phone terminals performing wireless communication The present invention relates to an access point and a one-phone service method.

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, a 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 wireless area provided by the Bluetooth AP, a wired telephone can be received through the Bluetooth AP. When the mobile communication terminal is not located in the wireless 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 wireless area 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, there is an urgent need to develop a wireless access point and one-phone service method capable of linking a wired incoming call received from an exchange to only a one-phone terminal desired by a caller.

By linking the wired incoming call only to the one-phone terminal in which the calling number is recorded in the memory, a wireless access point and one-phone service method are provided so that the caller can be linked only to the one-phone terminal of the caller who wants to make a call. It aims to do it.

In addition, the present invention transmits the wired incoming call to one or more other one-phone terminal capable of wireless communication when the one-phone terminal registered in the memory does not exist in the wireless area, the emergency call can not be connected An object of the present invention is to provide a wireless access point and a one-phone service method capable of preventing harm.

In order to achieve the above object and solve the problems of the prior art, the wireless access point of the present invention, a wireless communication module for performing wireless communication with one or more one-phone terminal, receives a predetermined wired incoming call from a switchboard via a wired telephone network.
