The communication company can provide various kinds of wired communication services, and the user can select desired wired communication services among various kinds of wired communication services. Therefore, the communication company needs to individually provide the wired communication service selected by each user. Wired communication services provided by the service provider may include xDSL, Ethernet, Giga Ethernet, G.hn, G.fast, and the like.

Specifically, the x Digital Subscriber Line (xDSL) service refers to a digital subscriber line service that enables data communication using a telephone line. The xDSL service includes an asymmetric digital subscriber line (ADSL) Speed digital subscriber line (MDSL), symmetric digital subscriber line SDSL (Symmetric DSL), high-speed digital subscriber line VDSL (very high speed DSL), popular asymmetric digital subscriber line UADSL (universal asymmetric DSL) A high bit rate DSL (digital subscriber line), which is a digital subscriber line, and the like. Here, as modulation and demodulation techniques for providing an xDSL service, there are a CAP (Carrierless Amplitude Phase Modulation) method, a DMT (Discrete Mutitone) method, a 2B1Q (2Bit 1Quaternary) method, a DWMT (Discrete Wavelet Multitone) method, a QAM Etc. can be utilized.

The Ethernet service and the Giga bit Ethernet service utilize a typical communication protocol of a local area network and can support communication using CSMA / CD (Carrier Sense Multiple Access with Collision Detection) . In particular, the Giga Ethernet service utilizes the Ethernet transmission technology which speeds up the transmission speed to 1 Gbps, and it can be a service applying the standardized technology to 1000BASE-X by the IEEE 802.3Z operation unit.

In addition, the G.hn service utilizes a data link layer, a physical racer, and a coexistence protocol corresponding to a standard for a next-generation wired home network to connect and share contents in all the wires of a user's home coaxial cable, Service can be provided. The G.fast service can provide services to support high-speed broadband networks using existing copper telephone lines.

Here, wired communication services such as xDSL, Ethernet, Giga Ethernet, G.hn, and G.fast are different from each other in the modulation / demodulation method and the communication protocol, so that it is necessary to provide a separate device for supporting each wired communication service . In particular, each user may select different types of wired communication services, and users within the same building may wish to receive different types of wired communication services. Accordingly, in order to provide a wired communication service desired by the user, the communication company may install the equipment corresponding to each wired communication service in duplicate. In this case, manpower and cost are required to install and maintain a large number of equipments, and power consumed by each equipments also increases. In addition, although a new type of wired communication service has emerged in recent years due to the development of wired communication technology, it is difficult to replace the equipment installed in the past with new equipment in a batch manner, and expansion to new wired communication service is not easy There is also a problem.

Here, by using the network connection device according to an embodiment of the present invention, it is possible to provide each wired communication service for each user without installing the individual devices redundantly in order to provide each wired communication service. Specifically, the network connection device according to an exemplary embodiment of the present invention can identify the type of the wired communication service using an input signal, and perform necessary digital signal processing according to the type of the wired communication service. Thus, with one network access device, it is possible to provide all the wired communication services desired by each user. Hereinafter, a network connection device according to an embodiment of the present invention will be described in detail.

1 is a block diagram showing a network connection apparatus according to an embodiment of the present invention. Referring to FIG. 1, a network connection apparatus according to an embodiment of the present invention may include a detection unit 10, a control unit 20, and a storage unit 30.

The detection unit 10 can receive an input signal from a communication network and can detect the type of wired communication service corresponding to the input signal. Here, the input signal may include one or more pin signals, and each pin signal may be input corresponding to a predetermined pin number.

Specifically, as shown in FIG. 2, the input signal may include a plurality of pin signals. 2 (a) is a graph showing respective pin signals supported by a standard connector RJ-45, which is generally used for connecting wires. That is, as shown in FIG. 2 (a), eight pin signals may be input to the RJ-45 connector, and pin numbers from 1 to 8 may be assigned to the respective pin signals.

In the case of the Ethernet service, as shown in FIG. 2 (b), two pairs of two pin signals may be included, and in accordance with the embodiment, the pin numbers 1, 2, 3, A signal can be input. In the case of the gigabit Ethernet service, as shown in Fig. 2 (c), four pairs of two pin signals may be included. That is, unlike the Ethernet service, the Giga Ethernet service can input pin signals to 8 pins. On the other hand, in the case of services such as xDSL, G.hn, and G.fast, pin signals can be input to two of the pin numbers 1 through 8. [ FIG. 2 (d) illustrates the input of pin signals to pin numbers 2 and 4, but pin signals may be input to two pin numbers arbitrarily selected from the eight pin numbers.

As described above, since the number and the pin number of the pin signal used in each wired communication service may be different, the detecting unit 10 may determine the number of the pin signal included in the input signal or the pin number It is possible to determine the type of each wired communication service. Further, in the case where two pin signals are inputted, the frequency can be used to distinguish.

A description will now be given of a specific method of distinguishing each wired communication service from the detection unit 10. First, when there are two or more groups of two pairs of pin signals, the detection unit 10 transmits the wired communication service to the Ethernet (Ethernet) -based services. As shown in FIG. 2 (d), the services such as xDSL, G.hn, and G.fast include only one pair of pin signals, so that a communication signal having two or more pairs is determined as the Ethernet-based service .

Hereinafter, among the Ethernet-based services, the general Ethernet service and the Gigabit Ethernet service can be distinguished by using the number of input pin signals. That is, as shown in FIG. 2 (b), the general Ethernet service uses two pairs of signals, namely, four pairs of pins. In the case of the Gigabit Ethernet service, four pairs, A total of 8 pin signals are used. Therefore, the detection unit 10 can identify the number of the pin signals included in the input signal, thereby distinguishing the general Ethernet service from the Gigabit Ethernet service.

In addition, there may be a service providing a speed of 500 Mbps or higher and a service providing a speed of 100 Mbps for the general Ethernet service having two pairs. In order to distinguish this, the detection unit 10 may first transmit a signal of 1GMbps according to an auto-negotiatino algorithm. Here, if there is a response to the 1Gbps, the service can be identified as a service providing a speed of 500Mbps or higher. If there is no response, it can be determined as a service providing a speed of 100Mbps.

On the other hand, when there is one group in which two pairs of pin signals form one pair, the frequency for the pin signal can be detected to determine the type of each wired communication service. More specifically, the detecting unit 10 can detect the frequency of the pin signal. If the frequency of the detected pin signal is 0 or more and less than 30 MHz, the detecting unit 10 discriminates the signal as xDSL (x digital subscriber line) If it is 30Mhz or more and less than 100Mhz, it can be judged as G.hn service. When the frequency of the pin signal is 100 MHz or more, it can be determined as a G.fast service. Standards for each of the xDSL, G.hn, and G.fast standards have been established, and the standard may include provisions for the frequency range of the input signal provided by each service. Therefore, the detection unit 10 can determine the type of each wired communication service by using the frequency of the pin signal.

After the detection unit 10 has determined the type of the wired communication service corresponding to each input signal, it can provide the determination result to the control unit 20.

The control unit 20 may convert the input signal by applying a control module corresponding to the detected wired communication service, and may provide the converted input signal to the predetermined domestic device UE. That is, since each of the wired communication services differs from the modulation / demodulation method and the communication protocol, it is necessary to apply an algorithm or profile corresponding to each wired communication service. To this end, the control unit 20 may apply a control module corresponding to the detected wired communication service to perform processing on the input signal in a manner suitable for each wired communication service. That is, by using the control module, each input signal can be converted into a form that can be processed by the domestic device UE.

At this time, the control unit 20 receives the control module from the storage unit 30 in which the control module corresponding to the type of the wired communication service is stored, or receives the control module from the cloud server (a) . Also, the control unit 20 can first check whether the control module corresponding to the detected wired communication service is stored in the storage unit 20, and if the control module necessary for the storage unit 20 is not stored , The control module may be provided from the cloud server (a). Therefore, even when a new wired communication service is added, a new wired communication service or the like is provided to the user in a manner of updating the control module in the storage unit 20 or the cloud server (a) . The control module may be an algorithm, a program, a profile, or the like corresponding to each wired communication service, and may mean a structure that is software. The control module may perform digital signal processing (DSP) on an input signal.

Here, the network connection device according to an embodiment of the present invention may be a collection device provided in an apartment basement terminal box, a street cabinet, etc. In addition, a network interface card (NIC) or a universal serial bus As shown in FIG.

3 and 4 are flowcharts illustrating a network connection method according to an embodiment of the present invention.

Referring to FIG. 3, a network access method according to an exemplary embodiment of the present invention may include a detecting step S100 and a service providing step S200.

Below. 3 and 4, a network connection method according to an embodiment of the present invention will be described.

In the detecting step S100, the type of the wired communication service corresponding to the input signal can be detected using the input signal received from the communication network. Here, input signals corresponding to different kinds of wired communication services may be input. In the detecting step (S100), the type of wired communication service corresponding to each input signal can be grasped through the input signal. The input signal may include one or more pin signals, and each pin signal may be input corresponding to a predetermined pin number.

4, first, a pin signal input to an input signal can be detected (S110). At this time, the number of pin signals and the pin number to be input can be grasped. Thereafter, when the two pin signals are paired, the type of the wired communication service can be distinguished through the number of pairs (S120). If the number of pairs is two or more, it can be discriminated as an Ethernet-based wired communication service and can be distinguished by Ethernet service or Gigabit Ethernet. If the number of pairs is less than two, xDSL, G.hn, G.fast. ≪ / RTI >

Accordingly, if the number of the pin signal pairs is two or more, it is possible to check whether there are four or more pairs of plate signals (S130). If the number of the pair of pin signals is four or more, (S131).

In addition, there may be a service providing a speed of 500 Mbps or higher and a service providing a speed of 100 Mbps for the general Ethernet service having two pairs. In order to distinguish this, a signal of 1GMbps can be transmitted according to an auto-negotiatino algorithm. Here, if there is a response to the 1Gbps, the service can be identified as a service providing a speed of 500Mbps or higher. If there is no response, it can be determined as a service providing a speed of 100Mbps.

On the other hand, when the number of the pin signal pairs is less than two, the frequency of the pin signal is detected first (S140), and each frequency range can be confirmed. Since xDSL, G.hn, and G.fast have different frequency ranges to support, each of the wired communication services can be distinguished using the frequency range. If the frequency of the pin signal is between 0 and 30 MHz (S141), it can be discriminated as the xDSL service (S142). If the frequency of the pin signal is 30 MHz or more and less than 100 MHz (S143) can do. When the frequency of the pin signal is 100 MHz or more (S143), it can be discriminated as the G.fast service (S144).

In the service providing step S200, the control module corresponding to the detected wired communication service may be applied to convert the input signal and transmit the converted input signal to the predetermined domestic device. That is, each of the wired communication services can use a different modulation / demodulation scheme or communication protocol, and therefore it is necessary to apply an algorithm or profile corresponding to the type of each wired communication service determined in the detection step S100 have. For this, in the service providing step (S200), a control module corresponding to the detected wired communication service may be applied, and the processing for the input signal may be performed in a manner suitable for each wired communication service. That is, by using the control module, each input signal can be converted into a form that can be processed by the corresponding domestic device UE. Here, the control module may perform digital signal processing (DSP) on an input signal.

At this time, in the service providing step (S200), the control module may be provided from a storage unit in which a control module corresponding to each type of wired communication service is stored. In an embodiment, the control module is provided from a separate cloud server Can receive. If it is determined that the control module corresponding to the detected wired communication service is not stored in the storage unit, if the control module required for the wired communication service is not stored in the storage unit, the control module received from the cloud server Embodiments are also possible.

The present invention is not limited to the above-described embodiments and the accompanying drawings. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
