Among the 4 lines installed in the building, two lines are used for telephone and PC data communication, the other lines are used for digital wireless communication.

Description

System and method for integrated wired / wireless communication and data communication services in buildings {METHOD AND SYSTEM OF THE INTEGRATED WIRE, WIRELESS, AND DATA COMMUNICATION FOR INSIDE THE BUILDING}

The present invention relates to an in-building communication relay method and system capable of integrating a general landline telephone, a personal computer (PC) data communication, and a digital wireless communication service in a building.

In a mobile communication service system, a base station and a mobile station communicate in a constant frequency band, and even though the entire city is covered by a plurality of base stations, a call shadow area that is not covered by the base station occurs in a building.

As such, in order to solve a call shadow area occurring in a tall building or an underground space, a technology for enabling a call by installing a repeater in the shadow area is used. In the mobile communication service system, a technology related to a relay for resolving a shadow area in a building is disclosed in Korean Laid-Open Patent Publication No. 2000-0074988.

The repeater method according to the prior art can be used only in one floor or one space inside the building, and radiates the radio waves throughout the building using a leaky coaxial cable or antenna to radiate the radio waves in the multiple floors.

However, in the prior art using a leaky coaxial cable, since the radio waves are radiated only in a passage through which the leaky coaxial cable passes, there is a disadvantage that a leaky coaxial cable should be constructed for each floor.

Accordingly, a first object of the present invention is to provide a communication service system and method that can replace a conventional repeater for a mobile communication service in a building.

In addition to the first object, a second object of the present invention is to provide a communication service system and method for in-building providing a landline telephone, wireless communication service, PC data communication service in one.

In order to achieve the above object, the present invention provides a method for relaying a mobile station in a building to a base station so as to transmit and receive a digital radio signal, wherein the wired communication network is a general wire telephone data, PC data signal and the digital radio By mixing the signals and using the four lines of telephone lines in the building, two lines are used for general telephone and PC data and the remaining two lines are transmitted to each premises in the building using the digital wireless data transmission path. The installed data line divider 70 separates the mixed signal spectrum into general telephone data, PC data, and digital wireless communication data, and converts the digital wireless communication data into line amplification, digital analog conversion, and frequency up conversion. A communication method is provided which relays to said mobile station. The.

As another embodiment of the present invention, the general wired telephone data, the PC data signal, and the wireless digital signal may be mixed and transmitted in one transmission path. In addition, the wired communication network may be used xDSL, that is, ADSL or VDSL network.

Hereinafter, with reference to the accompanying drawings, Figures 1 and 2 will be described in detail a preferred embodiment of the present invention.

The first embodiment of the present invention is a four-line wired transmission line (for example, xDSL transmission line) installed for data communication for telephone and personal computer (PC) except for two lines used for data communication for telephone and PC. The remaining two lines are used as digital wireless communication lines for mobile phones.

To this end, the present invention provides a data line mixer for relaying general landline telephone and PC data and wireless digital data for voice call through an xDSL line installed in a building, and a data line divider for distributing mixed data transmitted to each home. Characterized in having.

1 is a diagram illustrating an integrated system of wired and wireless data communication according to a first embodiment of the present invention. Referring to FIG. 1, a telephone station 10 mixes a general telephone signal and a PC data communication signal with an xDSL 20, such as ADSL or VDSL, to a terminal box 40 in a building or a complex through an optical line or other wired transmission line. Is sent.

At this time, the present invention is characterized in that a data line mixer 30 is provided to line-mix wireless wireless data for mobile communication together with a general wireline telephone signal and a PC data signal. That is, after receiving the RF analog signal generated by the base station 180 through the optical line 200 and the RF repeater 190 equipment installed in the building, the RF signal down to the IF frequency band (DNC; down converter; Down-converts through 170) and converts the IF analog signal into a digital signal using an analog-to-digital converter (ADC) 160.

All buildings have four lines of telephone transmission lines connected to Kaga Lake and a transmission line for the building's own network (keyphone). Of the four lines of transmission lines currently installed for data communication for telephone and PC, two lines are used for data communication for telephone and PC, and the other two lines are used for digital wireless communication.

At this time, since the respective spectrums 31, 32, and 33 have different distributions and different signal types, the interference between the signals can be minimized by using two independent transmission lines, and the data line mixer 30 ) Provides the highest quality service by optimizing the distortion and transmission line matching that can occur between each signal used.

Meanwhile, the digital wireless signal distributed through the data line divider 70 compensates for signal distortion of the wired line through the line amplifier 100, and converts the digital analog converter (DAC) 110 and the analog frequency up converter (UPC) 120. The RF signal generated by the first base station 180 is restored to serve the mobile station 140, and the signal generated by the mobile station 140 is transmitted to the base station in the reverse order.

According to a preferred embodiment of the present invention, a general telephone, modem, and repeater can be bundled and installed and maintained in one integrated device.

Then, it is transmitted to each building and apartment complex through the line amplifier LA 150. At this time, the data line mixer 30 according to the present invention mixes a general wireline telephone signal, PC data signal and wireless communication data. At this time, the spectrum 31 of the voice wireline telephone signal, the spectrum 32 of the data for the PC, and the wireless communication data 33 are mixed.

Referring to FIG. 2, the telephone station 10 mixes a general telephone signal and a PC data communication signal in a data mixer 31 to connect to a terminal box 40 in a building or a complex via a wired transmission line such as an xlsl 20 such as ADSL or VDSL. Is sent to.

That is, unlike the first embodiment, the second embodiment of the present invention is characterized in that general telephone data, PC data and wireless telephone digital data are mixed with each other and transmitted using 4 wired transmission networks.

The terminal or in-building terminal box 40 is then transmitted via the xDSL line 60 to the distributor equipment 50 in the building or complex, respectively. On the other hand, the signal transmitted to the home is distributed to the landline 31, the PC data communication 32 and the digital wireless communication service spectrum 33 through the data line distributor 70 leased and installed by the operator.
