The present invention relates to a wired and wireless communication service providing apparatus and method, and more particularly to a wired and wireless communication service providing apparatus and method for providing a communication service by wire or wireless.

Voice over Internet Protocol (VoIP) is a communication service technology that uses a packet network for data communication, which is used in the past, for an Internet phone, and converts voice data into Internet protocol data packets to enable a call in a general telephone network. In other words, VoIP service integrates telephone service by utilizing existing IP network as it is, and greatly reduces the line cost for telephone or fax transmission, so that telephone users can make long distance and international telephone service in internet and intranet environment with only local call fee. It has the advantage of receiving the user's attention is increasing.

The VoIP service continues to evolve, and can give a called number, which was not possible with a PC-to-phone method or a web-to-phone, and call quality is greatly improved. In addition, P2P (peer to peer) messenger-based VoIP service enables users to always make calls on the web by bypassing the firewall for voice calls that were difficult to execute due to security system (firewall) in existing messenger services such as MSN messenger and yahoo messenger. (E.g., Skeype, Allup, etc.), the user is gradually spreading.

Since the above-described P2P messenger-based VoIP service (hereinafter referred to as VoIP messenger service) has been generally provided through a wired method such as a headset with a microphone or a VoIP phone having a USB interface, the user can use the VoIP messenger service. There is an inconvenience to be present in front of the provided terminal, a method of adopting a short-range wireless communication method has been proposed to eliminate this disadvantage. That is, it is possible to use a VoIP messenger service wirelessly using a Bluetooth headset or a Bluetooth mobile phone that supports a Cordless Telephone Profile (CTP) without using a conventional wired method. In this case, in order to implement a P2P-based VoIP messenger service, a Bluetooth service called hardware and a Bluetooth host stack called a Bluetooth modem in a VoIP messenger service terminal such as a laptop, a PC, or a PDA running the VoIP messenger service is used. I installed a software driver for.

In addition, the LED operation and button for informing the state of the dongle 10 are operated, and a pairing operation for opening a communication line between devices without a user interface device such as a headset 7 is performed by the baseband processor 34. Run with extra CPU time. The Bluetooth profile 46 and USB driver 44 are also performed using the extra CPU time of the baseband processor 34.

When the Bluetooth USB audio dongle device 10 having the above-described configuration is inserted into the USB port 22 of the VoIP messenger service terminal 20, the Bluetooth USB audio dongle device 10 is inserted into the USB processor 32 embedded in the Bluetooth USB audio dongle device 10. As a result, the USB messenger service terminal 20 automatically detects the USB driver 24 and establishes USB-based communication between the Bluetooth USB audio dongle device 10 and the VoIP messenger service terminal 20.
