BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical communication system, and more particularly, to an integrated optical communication terminal including a wireless access point and an operation method thereof.

The optical communication system transmits and receives signals such as digital broadcasting and Internet / VOD (Video On Demand).

The optical line terminal OLT as the center device and the optical network terminals ONT as the optical communication terminal device can be connected to each other through one optical fiber line. Depending on the connection type, the connection structure of the ring type, the Pont-to-Pont, or the tree can be made.

Generally, in order to simultaneously transmit and receive signals from one point to another, a transmission cable and a receiving cable must be separately provided. However, since the optical fiber cable itself has a wide bandwidth characteristic, a signal can be transmitted in both directions through one optical fiber line when the transmission band and the reception band are separated. However, in order to realize bidirectional optical communication with one optical fiber line, a device for separating the light emitted from the light emitting device and the light received by the light receiving device must be provided in the ONT.

Particularly, in an Ethernet communication implemented by a ring network, when data is to be transmitted in both directions by using one optical fiber line, the optical network terminal (ONT), which is an optical communication terminal device, If a failure or power-off occurs in one, the function of the optical communication system becomes paralyzed.

Recent optical communication terminal devices are connected to a wired / wireless integrated network. Accordingly, the optical communication terminal apparatus is connected to a wireless AP (Access Point) apparatus. As a result, the optical communication terminal device and the wireless AP device constitute one integrated optical communication terminal device.

The wireless AP apparatus still functions as an access point even when a wired network such as an optical fiber line is disconnected or a failure occurs in such an integrated optical communication terminal apparatus. That is, the wireless AP device transmits an SSID (Service Set Identifier) or a BSSID (Basic Service Set Identifier) wirelessly. Accordingly, wireless access terminals such as a smart phone or a wireless office device recognize that the SSID or the BSSID is valid and try to communicate with the wireless AP device. As a result, the SSID or the BSSID transmitted from the wireless AP device in case of a failure of the wired network may cause the connection of the wireless access terminals to be invalidated.

In addition, the same or similar reference numerals shown in the drawings denote the same or similar components as possible. In some drawings, the connection relationship of elements and lines is shown for an effective explanation of the technical contents, and other elements or circuit blocks may be further provided.

Each embodiment described and exemplified herein may also include its complementary embodiment and the details of the basic operation of the optical communication terminal device and the wireless AP device and the functional circuits for signal transmission and reception are not intended to obscure the gist of the present invention Please note that it is not described in detail for the sake of brevity.

1 is a block diagram of a configuration of an integrated optical communication terminal apparatus according to an embodiment of the present invention. Referring to FIG. 1, the integrated optical communication terminal apparatus 300 includes a wireless AP apparatus 100 and an optical communication terminal apparatus 200. Communication between the wireless AP device 100 and the optical communication terminal device 200 is performed through a communication line L50. The communication line L50 may be a wired line or wireless. The integrated optical communication terminal device 300 may be connected to the wired / wireless integrated network 400 through a light path 10.

The wired / wireless integrated network 400 may include one or more of a mobile communication network, a wireless LAN, an Internet network, and a public switched telephone network. The wired / wireless integrated network 400 may provide a wired / wireless networking service by modulating an analog signal or a digital signal into an optical signal.

The optical line 10 connected between the wired / wireless integrated network 400 and the optical communication terminal device 200 may be implemented as a single optical fiber line. The optical line terminal 11 connected to the terminal E of the optical communication terminal apparatus 200 may be connected to the integrated optical communication terminal apparatus 300 different from the integrated optical communication terminal apparatus 300. In the case of optical signal transmission in the first direction (e.g., upward), an optical signal entering the optical path 10 may be provided to the optical path 11. [ On the other hand, in the case of the optical signal transmission in the second direction (for example, downward), an optical signal entering the optical path 11 may be provided to the optical path 10.

That is, the optical lines 10 and 11 can form an optical communication system of a ring structure. For convenience, the direction of transmission from West to East is forward direction, and the direction from East to West is reverse direction. However, this is given only for convenience of explanation in FIG. 1, and in the case where the matters are different, the directions opposite to each other may be called forward and backward directions.

For example, if the optical lines 10 and 11 are cut or damaged, optical communication failure, that is, failure due to the wired infrastructure may occur. In this case, the wireless AP device 100 of FIG. 1 is still in an alive state. However, a wireless access device such as a smart phone connected to the wireless AP device 100 tries to perform communication through the wired / wireless integrated network 400, but communication may not be performed when an optical communication failure occurs.

In the embodiment of the present invention, the optical communication terminal device 200 generates a hidden request signal requesting to hide the service set identifier when the optical communication failure occurs. The hidden request signal is transmitted to the wireless access point apparatus 100 via the communication line L50.

Therefore, the wireless access point 100 hides the SSID or the BSSID. Hiding here means to include or block the SSID or BSSID as invalid.

2 is a detailed block diagram of an optical communication terminal apparatus according to an embodiment of the present invention. Referring to FIG. 2, the optical communication terminal apparatus 200 includes an optical switch 210, first and second transceivers 220 and 230, a fault and power failure detector 240, and a controller 250. The optical communication terminal apparatus 200 may further include a power switch 295 and a power supply level detector 290.

The optical switch unit 210 may be applied to optical communication implemented, for example, in a ring network. The optical switch unit 210 transmits data in both directions using a single optical fiber line. In order to perform bidirectional optical communication, the optical switch unit 210 performs at least a 2x2 optical switching function in a normal communication operation and bypass switching when a communication failure occurs.

The optical switch unit 210 may include first, second, and third switches SW1, SW2, and SW3. The first switch SW1 switches between the first optical input / output terminal P1 and the first internal connection port P3 and the second switch SW2 switches between the second optical input / output terminal P4 and the second internal connection port P3. (P2). The third switch SW3 switches between the first optical input / output terminal P1 and the second optical input / output terminal P4 for bypass switching. The first, second, and third switches SW1, SW2, and SW3 perform a switching operation in response to a switching control signal provided from the controller 250.

Since only one optical switch unit 210 is provided in the optical communication terminal apparatus 200, the configuration of the optical communication terminal apparatus becomes compact and the implementation cost can be reduced.

The first optical input / output terminal P1 may indicate the West terminal, and the second optical input / output terminal P4 may indicate the East terminal.

The first optical input / output terminal P1 (W) may be connected to a single-core optical fiber 10 for bidirectional communication and the second optical input / output terminal P4 (E) may be connected to a single- Can be connected.

The wavelength used for the bidirectional communication may be, for example, 1310 nanometers and 1550 nanometers. Accordingly, when the first transceiver 220 receives the optical signal having the wavelength of 1550 nanometers in the first direction, it transmits the optical signal having the wavelength of 1550 nanometers in the second direction opposite to the first direction . Meanwhile, when the first transceiver 230 transmits an optical signal having a wavelength of 1550 nanometers in the first direction, the optical signal having the wavelength of 1550 nanometers can be received in the second direction.

Although the optical switch unit 210 is a 2x2 Ethernet optical switch in order to switch a broadcast signal, an Ethernet signal, or a wireless communication signal, the optical switch unit 210 may be an optical switch for switching other signals only by way of example.

The transceiver unit including the first and second transceivers 220 and 230 receives an optical signal received through the optical switch unit 210 and transmits a transmission optical signal through the optical switch unit 210.

The first transceiver 220 is connected between the second internal connection port P2 and the controller 250 to convert an upstream optical signal received through the optical switch 210 into an electrical signal, And converts the transmission signal to be transmitted into the transmission optical signal. The second transceiver 230 is connected between the first internal connection port P3 and the controller 250 to convert a downstream optical signal received through the optical switch 210 into an electrical signal, And converts the transmission signal to be transmitted into the transmission optical signal.

An optical path is formed through the line L20 in response to the switching of the first switch SW1 in the optical switch unit 210 so that the optical signal transmitted through the optical fiber line 10 is transmitted to the second transceiver 230 / RTI > Therefore, when the wavelength of the optical signal transmitted in the first direction (for example, downward) of the line L20 is 1310 nanometers, for example, the second direction (for example, upward) of the line L20, Lt; RTI ID = 0.0 > 1550 < / RTI > nanometers.

 In response to the switching of the second switch SW2, a light path through the line L10 is formed and an optical signal transmitted through the optical fiber line 11 is provided to the first transceiver 220. [ Therefore, when the wavelength of the optical signal transmitted in the first direction (e.g., downward) of the line L10 is 1550 nanometers, for example, the second direction of the line L10 (for example, upward) For example, 1310 nanometers.

The controller 250 provides the switching control signal to the optical switch unit 210. In the bypass switching mode, the third switch SW3 of the optical switch unit 210 connects the ports P1 and P4 in response to the switching control signal. Thus, the bypass function is implemented so that in the first direction, the optical signal received at the West is directly transmitted to the East without passing through the transceiver unit. Further, in the second direction, the optical signal received by the East is directly transmitted to the West without passing through the transceiver unit.

The fault and power source abnormality detector 240 receives the level of the power source. The fault and power source abnormality detector 240 can detect whether there is a wire network failure or a power source abnormality. The fault and power source abnormality detector 240 may receive a power detection error signal PDE from the power source level detector 290. When the power detection error signal (PDE) is received, the failure and power failure detection unit 240 may provide a power detection error to the controller 250. Accordingly, the controller 250 can apply the power switching signal PSS to the power switch 295 via the line L60. The integrated optical communication terminal device 300 can be driven by receiving the emergency power source 280 by performing the power switching function of the power switch 295.

The controller 250 may generate a switching control signal to cause the third switch SW3 in the optical switch unit 210 to switch when an optical communication failure occurs. Accordingly, the optical switch unit 210 operates in the bypass switching mode. The controller 250 generates a hidden request signal requesting to hide the service set identifier (SSID) when an optical communication failure occurs. The hidden request signal is transmitted to the wireless access point apparatus 300 via a line L50.

3 is a detailed block diagram of a wireless AP apparatus according to an embodiment of the present invention. Referring to FIG. 3, a wireless access point (AP) device 100 includes a wireless LAN controller 110, a first RF module 120, and a second RF module 130.

The first RF module 120 may be configured to couple wireless communication with at least one terminal 50 at a first radio frequency. Here, the first radio frequency may be 2.4 GHz. The second RF module 130 may be configured to couple wireless communication with at least one terminal 50 at a second radio frequency. Here, the second radio frequency may be 5 GHz.

The wireless LAN controller 110 controls the first and second RF modules 120 and 130. The LAN controller 110 communicates with the optical communication terminal device 200. The wireless LAN controller 110 may hide the service set identifier (SSID) or the BSSID when the hidden request signal is received. For example, the wireless LAN controller 110 may block the transmission of the SSID or the BSSID by controlling the first and second RF modules 120 and 130.

Therefore, the terminal 50 can not establish a communication connection with the wireless AP device 100. The terminal 50 quickly recognizes that the wireless AP device 100 is abnormal and searches for another wireless AP device. That is, the terminal 50 tries to establish a new communication connection with the new wireless AP device. Meanwhile, since the service set identifier (SSID) or the BSSID is normally transmitted when the failure is released, the terminal 50 and the wireless AP device 100 can be reconnected.

4 is a flowchart of a control operation according to an embodiment of the present invention. Referring to FIG. 4, in operation S400, the optical communication terminal device 200 receives an optical signal. More specifically, the controller 250 in the optical communication terminal apparatus 200 controls the operation of receiving the optical signal through the optical lines 10 and 11.

In operation S410, the controller 250 checks for a failure occurrence. The occurrence of the failure can be detected from the failure and power failure detector 240. In addition, the occurrence of the fault can be detected by the controller 250 directly checking the transceiver portion. For example, the intensity of the optical signal received at the time of cutting or defect of the optical path 10 may be weak or absent compared to the case of normal.

In operation S420, the controller 250 may detect the cause of the fault occurrence. The types of failures may include failures in the wired infrastructure and failures due to power failures. In addition, various types of obstacles may exist.

In operation S430, the controller 250 checks whether a fault has occurred in the wired network. That is, defects of the wired network include cutting or defects of the optical path 10. The failure of the wired network, which is a wired infrastructure, may mean that not all signals transmitted through the optical line 10 can be transmitted. Therefore, it is difficult for the wired data or wireless data transmitted through the wired network to be received by the integrated optical communication terminal device 300.

In the case of wired network failure, in operation S440 controller 250 requests to hide the service set identifier (SSID) or BSSID. That is, the controller 250 transmits a hidden request signal requesting to hide the service set identifier (SSID) or the BSSID to the wireless LAN controller 110 of the wireless access point device 300.

In operation S450, the controller 250 checks whether the fault has been restored. The failure recovery can be confirmed by, for example, communication with the terminal device itself or with the outside.

In the case of a failover, in operation S460, the controller 250 requests to activate the service set identifier (SSID) or the BSSID. That is, the controller 250 may transmit an activation request signal requesting activation of a service set identifier (SSID) or a BSSID to the wireless LAN controller 110 of the wireless access point device 300. Accordingly, the terminal 50 may again receive a service set identifier (SSID) or a BSSID included in the wireless packet.

On the other hand, if failure recovery is not completed, operation S440 is continuously performed.

Also, in operation S430, operation S470 is performed in the case where the cable network is not defective. In operation S470, cause resolution according to other defects is performed.

The embodiment of FIG. 4 may be embodied, for example, in software, hardware, or a recording medium readable by a computer or similar device using a combination of software and hardware. According to a hardware implementation, the embodiments described herein may be implemented as application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays May be implemented using at least one of processors, controllers, micro-controllers, microprocessors, and electrical units for performing other functions.

In some cases, the embodiments described herein may be implemented by the controller 180 itself. According to a software implementation, embodiments such as the procedures and functions described herein may be implemented with separate software modules. Each of the software modules may perform one or more of the functions and operations described herein. Software code can be implemented in a software application written in a suitable programming language. The software code is stored in the memory 160 and can be executed by the control unit 180. [

5 is a conceptual diagram illustrating terminal connection of wireless AP devices according to an embodiment of the present invention. Referring to FIG. 5, a wireless AP device 100 among a plurality of wireless AP devices 100, 101, and 102 forms a communication connection with a terminal 50 such as a smart phone.

In FIG. 5, a terminal 50 such as a smart phone can be wirelessly connected to the wireless AP device 100 through WiFi communication. The terminal 50 receives a service set identifier (SSID) or a BSSID included in a wireless packet of the wireless AP device 100 during Wi-Fi communication. IEEE 802.11 protocol can be applied to wireless LAN communication such as Wi-Fi communication.

The service set identifier (SSID) is an identifier uniquely assigned to the wireless AP device 100. A plurality of terminals or electronic devices receiving the service set identifier (SSID) may be connected at a time through the wireless AP device 100. [ The basic service set identifier (BSSID) is a MAC address uniquely allocated to the wireless AP device 100. The BSSID is used when each terminal identifies an access point (AP) in processing the IEEE 802.11 protocol.

First, in a preparatory operation for a wireless connection, the terminal 50 periodically receives a service set identifier (SSID) or a BSSID, and detects surrounding access points (APs). The terminal 50 may scan a plurality of service set identifiers (SSID) or BSSIDs provided from a plurality of wireless AP devices (100, 101, 102). A plurality of service set identifiers (SSIDs) or BSSIDs having the highest Received Signal Strength (RSS) or Signal to Noise Ratio (SNR) among a plurality of service set identifiers (SSIDs) or BSSIDs are searched. As a result, an access point (AP) that transmits a plurality of highly searched service set identifiers (SSID) or BSSIDs is determined as an access point (AP) to be wirelessly connected. Thereafter, if a signal for attempting to connect the determined access point (AP) is output from the terminal 50, an authentication procedure for wireless connection with the terminal 50 may be performed. After the execution of this authentication procedure, the terminal 50 is wirelessly connected to the determined access point 100 in a ratio.

In the embodiment of the present invention, the optical communication terminal apparatus 200 transmits a hidden request signal requesting to hide the service set identifier to the wireless access point apparatus 100 when the optical communication failure occurs. Accordingly, the wireless access point 100 hides the corresponding service set identifier (SSID) or the BSSID. That is, the wireless access point 100 does not transmit the service set identifier (SSID) or the BSSID.

Accordingly, the terminal 50 scans a plurality of service set identifiers (SSIDs) or BSSIDs provided from the other wireless access point devices 101 and 102. Therefore, the terminal 50 can be newly wirelessly connected to one of the wireless access point devices 101, 102.

The application of the present invention is not limited to the FTTH (Fiber To The Home) method. In addition, although the communication method using a single optical cable has been described, considering that the voice telephone service, the internet service, and the cable broadcasting service are provided to each household through different lines, such services are also provided as a pair of optical cables .

As described above, an optimal embodiment has been disclosed in the drawings and specification. Although specific terms have been employed herein, they are used for purposes of illustration only and are not intended to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. For example, when the matter is different, the detailed configuration of the optical communication terminal apparatus and the internal connection configuration with the wireless AP apparatus can be changed and changed without departing from the technical idea of the present invention.
