Description

CONNECTION APPARATUS FOR INTERNET OF WIRE / WIRELESS MULTIPLEX}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wired / wireless hybrid Internet access device, and provides Internet data and telephone services to Internet telephones, general telephones, and wireless terminals in homes and small offices using xDSL (hereinafter referred to as xDSL). The present invention relates to a wired / wireless hybrid Internet access device.

In recent years, the demand for telephone service users using the Internet network is increasing because the telephone service charges are low and there are advantages such as providing additional services due to interworking with data communication.

Conventional Internet telephone calls are possible using Internet telephones or ordinary telephones, where a telephone service using a general telephone network where additional services are not supported is called Plain Old Telephone Service (POTS).

That is, the prior art operating as described above, the Internet phone call is possible using a normal telephone or an Internet telephone, that is, the terminal equipped with a wireless module is not possible to receive a variety of services because the Internet phone call is impossible, There was a problem that causes inconvenience to the user.

Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a wired / wireless hybrid Internet apparatus that provides Internet data and telephone service to a general telephone, an Internet telephone, and a wireless telephone using xDSL with a wired / wireless composite Internet access apparatus. have.

The present invention for achieving the above object is an xDSL interface unit for exchanging data with a digital subscriber line (DSL) matching device; A main control unit which receives data from the xDSL interface unit, processes and converts and controls a protocol corresponding to each component unit; An Ethernet interface unit used for interworking with an Internet telephone or a LAN device by a control signal from the main controller; A public switched telephone network (PSTN) interface unit performing a function of a normal telephone by a control signal from the main controller; A wireless unit transmits and separates data from the main control unit and compresses voice.

Hereinafter, the application and effects of the wired / wireless composite Internet access device according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing the configuration of the wired / wireless hybrid Internet access device according to the present invention, as shown therein, and an xDSL interface unit 310 for exchanging data with a digital subscriber line matching device; A main controller 350 which receives data from the xDSL interface 310 and processes and converts and controls a protocol corresponding to each component; An Ethernet interface unit 320 used for interworking with an Internet telephone or a LAN device by a control signal from the main controller 350; A public switched telephone network interface (330) for performing a function of a general telephone by a control signal from the main controller (350); The wireless controller 340 transmits and separates data from the main controller 350 and compresses voice.

Here, the xDSL interface 310 is composed of an analog front end (AFE) 311, which is an xDSL line matching unit, and an xDSL modem unit 312, and the Ethernet interface 320 Ethernet control unit 321 for outputting a control signal to the Ethernet, and Ethernet PHY (322), the public switched telephone network interface unit 330 is a digital signal processor 331 that performs call processing functions such as voice compression and tone detection And a SLIC / codec unit 332 for converting a signal, and the wireless unit 340 includes a Bluetooth baseband processor including a foreword error correction unit (FEC), a compression unit and a frequency selector (FEC). 341) and the RF sub-module 342 which separates transmission and reception data transmission by the TDI method using the frequency hopping method.

First, the xDSL interface unit 310 enables data exchange with a digital subscriber line matching device, which is a matching device of xDSL clients, and the main control unit 350 receiving data from the xDSL interface unit 310 is configured for each component. Process and convert the protocol corresponding to the department and control each component.

Then, the Ethernet interface 320 can be used when interworking with the Internet phone or the LAN equipment by the control signal from the main controller 350, and the public switched telephone network interface 330 is the main controller 350 The control signal from) allows you to perform the functions of a normal telephone.

Now, the wireless unit 340 separates data by the control signal from the main control unit 350, compresses the voice data, corrects an error, and transmits / receives data in a TD manner through the RFID submodule 342 provided. It will separate the transmission.

Here, the telephone service supported by the wired / wireless Internet complex device will be described through the respective paths through the above configuration unit.
