1, an IPTV service environment according to an embodiment of the present invention may include a wireless relay device 10 for providing an Internet connection environment of an IPTV service, and a plurality of domestic devices 20 .

The wireless relay apparatus 10 refers to an AP providing an Internet access environment for receiving an IPTV service, for example, broadcasting contents, Internet contents, and VoD (Video on Demand) services.

The domestic device 20 refers to a device that connects to the Internet through a wired or wireless connection to the wireless relay device 10 and includes an IPTV service provided by a service provider (not shown) via the wireless relay device 20, And a set-top box for receiving broadcast contents, Internet contents, VoD (Video on Demand) services, and the like, but the present invention is not limited thereto. For example, devices such as Internet telephones, IOT devices, .

Meanwhile, in the case of the wireless relay apparatus 10 in the IPTV service environment in which the conventional optical communication technology is incorporated, the subscriber optical signal terminates at the home office side, and is installed in the home office to connect the backbone network and the subscriber- It is common to provide an Internet access environment through a wired network connection with an optical line terminal (OLT) constituting a net.

However, in such an Internet access environment provided through a wired network, a fault may occur on the wired network due to line cutting, equipment power problem, etc., and if a failure occurs in the wired network, There is a problem that a normal Internet access environment can not be provided.

Accordingly, in an embodiment of the present invention, in connection with the wireless relay apparatus 10 providing an Internet access environment for an IPTV service, a wireless connection mode for connecting through a wired network and a wireless connection mode for connecting via a wireless network are switched In the following, the configuration of the radio relay apparatus 10 for realizing this will be described in detail.

In the meantime, prior to the description, there may be two or more wireless networks to which the wireless relay apparatus 10 can connect according to an embodiment of the present invention. In such two or more wireless networks, A macro cell having a relatively large cell coverage of a macro cell and a small cell having at least a part of a coverage of the macro cell as a small cell, ), A pico cell, and a femtocell.

FIG. 3 shows a schematic configuration of a radio relay apparatus 10 according to an embodiment of the present invention.

3, the radio relay apparatus 10 according to an embodiment of the present invention includes a selector 11 for selecting a radio network, and a controller 12 for controlling a connection mode of the radio relay apparatus 10 ). ≪ / RTI >

All or a part of the configuration of the radio relay apparatus 10 including the selection unit 11 and the control unit 12 may be implemented in a form of a hardware module or a software module or a combination of a hardware module and a software module Can also be implemented.

Here, the software module can be understood as, for example, a command executed by a processor that controls an operation in the wireless relay device 10, and the command may have a form stored in a memory in the remote management device 20 There will be.

The wireless relay apparatus 10 according to an embodiment of the present invention includes, in addition to the above-described configuration, a wired communication module for performing a substantial communication function for connection to a wired network, And a wireless communication module (e.g., an LTE modem) that is responsible for the wireless communication module 13.

Such a communication unit 13 may include, but is not limited to, an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, But may include all known circuits to perform.

As a result, the radio relay apparatus 10 according to the embodiment of the present invention can switch and control the respective operation modes corresponding to the wired connection mode and the wireless connection mode based on the above-described configuration. Hereinafter, The configuration of the radio relay apparatus 10 will be described in more detail.

The selection unit 11 performs a function of selecting a wireless network to which the wireless relay apparatus 10 is to be connected (hereinafter, a wireless network to be connected).

More specifically, when the switching event for the wired connection mode occurs while the wired connection mode for connecting to the Internet via the wired network is maintained as the normal operation mode, the selection unit 11 selects the radio relay apparatus 10 Selects a connection target wireless network to be connected.

Here, it can be understood that the switch event is a case in which a fault occurs in the wired network practically due to, for example, line disconnection in the wired network, a problem in the equipment power source, or the like, or a failure is expected.

At this time, the selection unit 11 selects one of the connection state information about the domestic device 20 connected to the radio relay apparatus 10 and one of two or more wireless networks connectable to the radio relay apparatus 10 The wireless network to be connected can be selected by using the switching policy information defined for selection as a wireless network.

That is, when the specific domestic device (e.g., set-top box) having the size of the data traffic transmitted and received through the wired network is determined to be equal to or larger than the critical size from the connection state information, It is possible to select a specific wireless network having the largest received signal strength (RSSI) as a connection target wireless network.

Here, the largest received signal strength (RSSI) among the two or more networks means that data traffic can be transmitted stably, and it can be determined from the connection state information that the data traffic transmitted and received through the wired network is a specific home When the presence of a device (e.g., a set top box) is confirmed, a wireless network capable of reliably transmitting data traffic is selected as a connection target wireless network, thereby ensuring stable Internet access to the domestic device.

On the other hand, in the case of a specific domestic device (e.g., set-top box) in which the size of data traffic transmitted and received through the wired network is greater than or equal to a critical size, a time zone in which data traffic is mainly used, that is, a main transmission / . In one embodiment of the present invention, the connection target wireless network can be selected by further considering such a main transmission / reception time zone.

That is, the selection unit 11 determines that the specific domestic device (e.g., set-top box) having the size of the data traffic transmitted and received through the wired network is equal to or larger than the critical size from the connection state information, : A settop box), or a wireless network capable of stably transmitting data traffic is selected as a connection target wireless network when the wireless terminal belongs to a main transmission / reception time slot in which data traffic is transmitted / received, or when the main transmission / , It is possible to guarantee stable Internet access to the relevant domestic devices

In addition, when the connection of state-of-the-art devices whose size of data traffic transmitted / received through the wired network is smaller than the critical size is confirmed from the connection state information (e.g., when the set-top box is powered off) It is possible to select one of the remaining wireless networks except the specific wireless network having the highest received signal strength among the two or more networks as a wireless network to be connected.

Here, when the size of data traffic transmitted / received through the wired network from the connection state information is less than the critical size, it means that data traffic can be transmitted even in a wireless network having a relatively poor wireless environment. When only the connection of the domestic device whose size of the data traffic transmitted and received through the network is less than the critical size is confirmed, the wireless network with relatively poor wireless environment can be selected as the connection target wireless network.

The selection of a wireless network having a relatively poor wireless environment as a connection target wireless network is performed in order to prevent an overload phenomenon in which a plurality of wireless relay devices are connected to a wireless network having a good wireless environment in a certain area (e.g., apartment complex) Thereby ensuring an Internet access environment for a set-top box in which data traffic is relatively large among domestic devices connected to the respective wireless relay devices, thereby providing a stable IPTV service.

The control unit 12 performs a function of controlling the switching of the operation mode.

The control unit 12 switches the operation mode of the wireless relay apparatus 10 from the wired connection mode to the wireless connection mode when the connection target wireless network to be connected to the wireless relay apparatus 10 is selected according to the occurrence of the switching event Thereby enabling connection to the Internet through the wireless network to be connected to each of the domestic devices 20 connected to the wireless relay apparatus 10.

On the other hand, in the case of a switch event, a case where the data transmission speed in the wired network is lowered to a critical speed or less, which is not usable in the wired network due to disconnection or the like, may be included.

In this regard, when the data transmission rate in the wired network is lowered below the critical speed, the control unit 12 determines that some of the domestic devices connected to the wireless relay apparatus 10 are connected to the wired network through the wired network And the remaining domestic devices can simultaneously maintain the wired connection mode and the wireless connection mode so as to transmit and receive the data traffic through the connection target wireless network.

At this time, the control unit 12 sequentially connects the wired network connections to the other domestic devices except for the set-top box among the domestic devices 20 connected to the wireless relay device 10 so that the data transmission speed in the wired network is sufficient for providing the IPTV service And can be connected to a wireless network.

Here, the disconnection procedure for the wired network is to sequentially release the home appliance using a service having a low real-time property, or to sequentially release the home appliance having less data traffic or to sequentially release the home appliance having a large traffic .

Of course, when the data transmission speed in the wired network is lowered, the control unit 12 may first release the connection to the set-top box among the domestic devices 20 connected to the wireless relay apparatus 10 and transmit the stable IPTV service It is needless to say that it is also possible to maintain the connection of other domestic devices to a wired network having a low data transmission speed or an unstable wired network.

The control method of simultaneously maintaining the wired connection mode and the wireless connection mode is as follows. For example, when the data transmission speed of the wired network is lowered during the VOD service through the set-top box, the wireless network is additionally connected to pre-buffer the VOD contents And can also be used to prepare for a failure in a wired network.

As described above, according to the configuration of the wireless relay apparatus 10 according to an embodiment of the present invention, a method for switching control between a wired connection mode connected through a wired network and a wireless connection mode connected through a wireless network A stable Internet connection environment can be ensured by controlling switching to a wireless network even when a failure occurs in a wired network.

Hereinafter, an operation method of the radio relay apparatus 10 according to an embodiment of the present invention will be described with reference to FIGs. 4 and 5. FIG.

4, when the switching event for the wired connection mode occurs while the wired connection mode for accessing the Internet through the wired network is maintained, the selection unit 11 is a normal operation mode, The device 10 selects a connection target wireless network to be connected (S10-S30).

Here, it can be understood that the switch event is a case in which a fault occurs in the wired network practically due to, for example, line disconnection in the wired network, a problem in the equipment power source, or the like, or a failure is expected.

At this time, the selection unit 11 selects one of the connection state information about the domestic device 20 connected to the radio relay apparatus 10 and one of two or more wireless networks connectable to the radio relay apparatus 10 The wireless network to be connected can be selected by using the switching policy information defined for selection as a wireless network.

5, when a particular domestic device (e.g., a set-top box) having a size of data traffic transmitted and received through a wired network is not less than a critical size from the connection state information, A specific wireless network having the largest received signal strength (RSSI) among two or more possible networks can be selected as a connection target wireless network (S31-S33).

Here, the largest received signal strength (RSSI) among the two or more networks means that data traffic can be transmitted stably, and it can be determined from the connection state information that the data traffic transmitted and received through the wired network is a specific home When the presence of a device (e.g., a set top box) is confirmed, a wireless network capable of reliably transmitting data traffic is selected as a connection target wireless network, thereby ensuring stable Internet access to the domestic device.

On the other hand, in the case of a specific domestic device (e.g., set-top box) in which the size of data traffic transmitted and received through the wired network is greater than or equal to a critical size, a time zone in which data traffic is mainly used, that is, a main transmission / . In one embodiment of the present invention, the connection target wireless network can be selected by further considering such a main transmission / reception time zone.

That is, the selection unit 11 determines that the specific domestic device (e.g., set-top box) having the size of the data traffic transmitted and received through the wired network is equal to or larger than the critical size from the connection state information, : A settop box), or a wireless network capable of stably transmitting data traffic is selected as a connection target wireless network when the wireless terminal belongs to a main transmission / reception time slot in which data traffic is transmitted / received, or when the main transmission / , It is possible to guarantee stable Internet access to the relevant domestic devices

In addition, when the connection of state-of-the-art devices whose size of data traffic transmitted / received through the wired network is smaller than the critical size is confirmed from the connection state information (e.g., when the set-top box is powered off) One of the remaining wireless networks except the specific wireless network having the highest received signal strength among the two or more networks may be selected as a connection target wireless network according to the information (S31, S32, S34)

Here, when the size of data traffic transmitted / received through the wired network from the connection state information is less than the critical size, it means that data traffic can be transmitted even in a wireless network having a relatively poor wireless environment. When only the connection of the domestic device whose size of the data traffic transmitted and received through the network is less than the critical size is confirmed, the wireless network with relatively poor wireless environment can be selected as the connection target wireless network.

The selection of a wireless network having a relatively poor wireless environment as a connection target wireless network is performed in order to prevent an overload phenomenon in which a plurality of wireless relay devices are connected to a wireless network having a good wireless environment in a certain area (e.g., apartment complex) Thereby ensuring an Internet access environment for a set-top box in which data traffic is relatively large among domestic devices connected to the respective wireless relay devices, thereby providing a stable IPTV service.

4, when the connection target wireless network to be connected to the wireless relay device 10 is selected according to the occurrence of the switching event, the controller 12 determines the operation mode of the wireless relay device 10 in the wired connection mode, Thereby enabling connection to the Internet through the wireless network to be connected to each of the domestic devices 20 connected to the wireless relay apparatus 10 (S40).

On the other hand, in the case of a switch event, it may include a case where the data transmission rate in the wired network is lowered to a critical speed or less, which is not usable in the wired network.

In this regard, when the data transmission rate in the wired network is lowered below the critical speed, the control unit 12 determines that some of the domestic devices connected to the wireless relay apparatus 10 are connected to the wired network through the wired network And the remaining domestic devices can simultaneously maintain the wired connection mode and the wireless connection mode so as to transmit and receive the data traffic through the connection target wireless network.

At this time, the control unit 12 sequentially connects the wired network connections to the other domestic devices except for the set-top box among the domestic devices 20 connected to the wireless relay device 10 so that the data transmission speed in the wired network is sufficient for providing the IPTV service And can be connected to a wireless network.

Here, the disconnection procedure for the wired network is to sequentially release the home appliance using a service having a low real-time property, or to sequentially release the home appliance having less data traffic or to sequentially release the home appliance having a large traffic .

Of course, when the data transmission speed in the wired network is lowered, the control unit 12 may first release the connection to the set-top box among the domestic devices 20 connected to the wireless relay apparatus 10 and transmit the stable IPTV service It is needless to say that it is also possible to maintain the connection of other domestic devices to a wired network having a low data transmission speed or an unstable wired network.

The control method of simultaneously maintaining the wired connection mode and the wireless connection mode is as follows. For example, when the data transmission speed of the wired network is lowered during the VOD service through the set-top box, the wireless network is additionally connected to pre-buffer the VOD contents And can also be used to prepare for a failure in a wired network.

As described above, according to the operation method of the wireless relay apparatus 10 according to an embodiment of the present invention, a method for switching control between a wired connection mode connected through a wired network and a wireless connection mode connected through a wireless network It is possible to guarantee a stable Internet access environment by controlling the switching to the wireless network even when a failure occurs in the wired network.
