Description

The network is being built.

In the case of an existing broadband network, an ACS (Auto Configuration Server) through a base station connected by wire (e.g., an optical LAN cable) to a router that forms a network with a plurality of devices placed in the customer's home It is directly connected to, and the router may receive connection setting information for creating a wireless communication connection with the base station from the ACS.

Meanwhile, FIG. 2 is a block diagram illustrating the structure of a 5G CPE 10 according to an embodiment of the present invention.

Referring to FIG. 2, the 5G CPE 10 related to the present invention is connected to the control unit 100 and the control unit 100, and is controlled by the control unit 100, the first communication unit 110, the second communication unit. It may be configured to include 120 and the third communication unit 130. It may also include a memory 140. The components shown in FIG. 2 are not essential to implement the 5G CPE 10, so the 5G CPE 10 described herein may have more or fewer components than the components listed above. have.

First, the first communication unit 110 is for supporting short-range communication with the router 20, and uses at least one of Bluetooth™, Radio Frequency Identification (RFID), Near Field Communication (NFC), and ZigBee technology. By using, communication with the router 20 can be connected. Alternatively, the first communication unit 110 may perform communication with the router 20 by wire through a wired cable such as a local area network (LAN) cable.

The second communication unit 120 is for wide area networks, and uses at least one of Wi-Fi (Wireless-Fidelity), Infrared Data Association (IrDA), and UWB (Ultra Wideband) technologies. Thus, wireless communication with the router can be performed.

Both the first communication unit 110 and the second communication unit 120 may be formed to connect communication with the router 20. In this case, the first communication unit 110 may receive router device information from the router 20 when a communication connection is established with the router 20 in a wired or near distance. Here, the router device information is information necessary for authentication of the router 20, and may be information including information such as vendor information, a software version, and a MAC address of the router 20.

On the other hand, the second communication unit 120, when a connection according to a wireless communication interface that can be connected to the 5G base station 30 is requested from the router 20, between the router 20 and the 5G base station 30 Wireless connection can be made. That is, the router 20 may generate a wireless communication interface accessible to the second communication unit 120 based on the connection setting information received from the 5G base station 30, and the control unit 100 By controlling 120, wireless connection with the router 20 may be performed through the second communication unit 120.

Meanwhile, the third communication unit 130 may transmit and receive 5G signals with the 5G base station 30. To this end, the third communication unit 130 may transmit one or more 5G transmission signals to the 5G base station 30. In addition, the third communication unit 130 may receive one or more 5G reception signals from the 5G base station.

In this case, the 5G frequency band may use the same band as the 4G frequency band, and this may be referred to as LTE re-farming. Meanwhile, as the 5G frequency band, the Sub 6 band, which is a band of 6 GHz or less, may be used.

On the other hand, the third communication unit 130 may use a millimeter wave (mmWave) band as a 5G frequency band in order to perform broadband high-speed communication. When a millimeter wave (mmWave) band is used, the 5G CPE 10 may perform beam forming for communication coverage expansion with a base station.

Meanwhile, regardless of the 5G frequency band, in a 5G communication system, a larger number of multiple input multiple outputs (MIMO) can be supported to improve transmission speed. In this regard, uplink (UL) MIMO may be performed by a plurality of 5G transmission signals transmitted to the 5G base station. In addition, downlink (DL) MIMO may be performed by a plurality of 5G reception signals received from the 5G base station.

Meanwhile, the memory 140 stores data supporting various functions of the 5G CPE 10. The memory 140 may store a plurality of application programs (application programs or applications) driven by the 5G CPE 10, data for the operation of the 5G CPE 10, and instructions. At least some of these application programs may be downloaded from an external server through wireless communication.

In addition, at least some of these application programs may exist on the 5G CPE 10 from the time of shipment for the basic functions of the 5G CPE 10. Meanwhile, the application program may be stored in the memory 140, installed on the 5G CPE 10, and driven by the controller 100 to perform an operation (or function) of the 5G CPE 10.

In addition to the operation related to the application program, the control unit 100 generally controls the overall operation of the 5G CPE 10. In addition, the controller 100 may control at least some of the components described in FIG. 2 in order to drive the application program stored in the memory 140. Furthermore, in order to drive the application program, the control unit 100 may operate by combining at least two or more of the components included in the 5G CPE 10 with each other.

Meanwhile, the controller 100 may perform a wireless connection between the router 20 and the 5G base station 30 according to whether the router 20 is connected through the first communication unit 110. That is, when the router 20 is first connected through the first communication unit 110, the control unit 100 transmits the router device to the first communication unit 110 based on the router device information received through the first communication unit 110. The router 20 that transmitted the information can be authenticated.

And when the router 20 is authenticated, the received router device information is transmitted to the ACS 31 through the 5G base station 30, and connection setting information for connecting wireless communication with the 5G base station 30 is transmitted to the router. Can be sent to (20). And when the router 20 requests a wireless communication connection through the connection setting information, by connecting the router 20 through the second communication unit 120, the wireless communication between the router 20 and the 5G base station 30 Connection can be made.

In this case, when the router 20 and the 5G base station 30 are connected by the WiFi method, the control unit 100 wirelessly connects the 5G base station 30 to the 5G base station 30 through a 5G communication method using Sub 6 or mmWave frequency through the third communication unit 130. At least one service provider 32 connected to the 5G base station 30 and the router 20 by performing communication and performing wireless communication with the router 20 through the second communication unit 120 through a WiFi connection. Data can be relayed between a plurality of electronic devices connected to ).

3 is a flowchart illustrating an operation process of connecting a router and a 5G base station by a 5G CPE 10 according to an embodiment of the present invention. And FIG. 4 is an exemplary diagram illustrating a process of generating a communication interface between a router and a 5G base station through a 5G CPE according to the operation process of FIG. 3.

First, referring to FIG. 3, the controller 100 of the 5G CPE 10 according to an embodiment of the present invention, as shown in FIG. 4A, the router 20 through the first communication unit 110. ) Can be detected whether it is connected (S300).

As an example, if the first communication unit 110 is connected to the router 20 through a wired cable, the control unit 100 controls the first communication unit 110 when a wired cable connected to the router 20 is connected. Through it can be detected that the router 20 is connected.

However, if the first communication unit 110 is connected to the router 20 through an NFC tag or RFID, the control unit 100 may detect a preset NFC tag or RFID through the first communication unit 110. It can be detected that the router 20 is connected.

Alternatively, if the first communication unit 110 is connected to the router 20 through a near-distance communication method requiring approval for connection, such as a Bluetooth method, the controller 100 It is possible to detect a connection signal and approve the connection according to the connection signal, that is, a Bluetooth signal. In this case, the Bluetooth signal may include preset identification information, and the controller 100 may automatically approve Bluetooth connection accordingly when the received Bluetooth signal includes preset identification information. In addition, when the Bluetooth connection is approved, it may be detected that the router 20 is connected through the first communication unit 110. To this end, the memory 140 may store preset NFC tag or RFID information or preset Bluetooth identification information.

When the connection of the router 20 is detected through the first communication unit 110, the control unit 100 may receive router device information through the first communication unit 110 (S302 ).

For example, when the router 20 is connected through an NFC tag or RFID, information stored in the NFC tag or information stored in the RFID may be the router device information. In this case, the router device information of the router 20 may be received at the same time as the NFC tag becomes the first communication unit 110 or the RFID is sensed.

However, when the first communication unit 110 is connected to the router 20 through a wired cable or a Bluetooth method, router device information of the router 20 may be received through the wired cable or a Bluetooth method.

Meanwhile, the step S302 may further include authenticating the router 20 according to the received router device information. For example, when the router device information is received, the controller 100 may authenticate the connected router 20 by notifying the user that the received router device information is present. To this end, any one of the first communication unit 110 to the third communication unit 130 of the 5G CPE 10 may further perform wireless communication with another device for outputting the notification.

For example, the other device may be a user's mobile terminal. In this case, the user may check the router attempting to connect to the 5G CPE 10 through the notification information, and authentication of the router may be performed according to the user's selection.

Meanwhile, it goes without saying that the authentication of such a router may be performed in advance. For example, the user may perform pre-authentication through the other device (authentication device), that is, a mobile terminal, before step S300, and the controller 100 may perform pre-authentication through the first communication unit 110 only. Whether or not the router 20 is connected can be detected. To this end, at least one of the first to third communication units 110 to 130 may be communicatively connected with the authentication device.

Such pre-authentication may be performed through an NFC tag provided in the mobile terminal or an application of the mobile terminal. For example, when pre-authentication is performed through an NFC tag, the controller 100 may detect pre-authentication according to whether the NFC tag attached to the authentication device (eg, the user's mobile terminal) is tagged. Meanwhile, when pre-authentication is performed through an application of the mobile terminal, the pre-authentication may be detected based on a signal received from the mobile terminal when the application is driven.

In this case, when authentication information such as NFC tag information or preset encryption information is received from the authentication device, the control unit 100 receives the device information of the router within a certain time from the time when the authentication information is received, and the router authenticated by the user. Can be identified as. Accordingly, router device information received within a predetermined time from the time when the authentication information is received may be transmitted to the ACS 31.

Meanwhile, the authentication of the router may include a process of verifying whether the router is connectable to the 5G CPE 10 according to the router device information. That is, the controller 100 may check software version and vendor information such as an operating system of the router 20 according to the router device information, and may determine whether the 5G CPE 10 is a supported router as a result of the check. In addition, if the router 20 is not supported, the connection with the router 20 may be blocked. In this case, the controller 100 may inform the user that the router 20 is not supported. To this end, any one of the first communication unit 110 to the third communication unit 130 of the 5G CPE 10 may further perform wireless communication with another device for outputting an unsupported notification of the router 20.

Meanwhile, when the router device information received in step S302 is received, or when the router 20 is authenticated through the received router device information, the controller 100 may transmit the received router device information to the ACS 31. To this end, the controller 100 may transmit the received router device information to the 5G base station 30 through the third communication unit 130 (S304). Then, the router device information may be transmitted to the ACS 31 through the 5G base station 30 as shown in FIG. 4B (400).

Meanwhile, when the router device information is received, the ACS 31 may perform communication connection with the router 20 according to the router device information. To this end, the ACS 31 may transmit connection setting information to the router 20 according to a preset protocol, and perform wireless connection with the router 20 through a communication interface formed according to the connection setting information.

Here, the preset protocol may be a TR 69 protocol and a TR 181 protocol. Here, the TR 69 protocol may be a protocol for creating a communication interface by first creating an object in order to create a communication connection with the router 20 and setting parameter values according to the created object, and the TR 181 protocol is The parameter values according to the created object may be a defined protocol. Here, the communication interface may be an interface for receiving 5G communication service.

The ACS 31 may transmit connection setting information to create an object for forming the communication interface. Here, the connection configuration information may include information for configuration of the 5G CPE 10. The 5G CPE 10 configuration information may include SSID information for wireless WIFI configuration, and may include information on a service type, speed, authentication value, and in-house device type to which a subscriber has subscribed.

In addition, the connection setting information transmitted from the ACS 31 may be received by the 5G CPE 10 in response to the transmission of the router device information. Then, the controller 100 may transmit the received connection setting information to the router 20 (S306). Therefore, as shown in (c) of FIG. 4, the connection setting information transmitted from the ACS 31 may be transmitted to the router 20 (402).

Meanwhile, the router 20 may generate a communication interface based on the received connection setting information. And it is possible to request a wireless communication connection to the 5G CPE 10 through the generated communication interface. Here, the communication interface may be a communication interface for a wide area network (WAN) point to point protocol (PPP) connection (WANPPPConnection).

Then, the 5G CPE 10 may connect wireless communication according to the communication interface with the router 20 (S308). In this case, the 5G CPE 10 and the router 20 may be connected through the second communication unit 120 according to the WAN PPP connection.

In this case, if the first communication unit 110 is connected to the router 20 according to the Bluetooth method, the control unit 100 may disconnect the first communication unit 110 and the router 20. In addition, the control unit 100 may block a connection through a wired cable. In this case, even when the user releases the wired cable, the connection between the 5G CPE 10 and the router 20 through the second communication unit 120 may be maintained.

Then, the router 20 may be connected to the service providers 32 connected to the 5G base station 30 through the generated communication interface. Accordingly, a plurality of electronic devices connected to the router 20 may also be connected to the service providers 32.

Meanwhile, the connection setting information includes information for creating an object (interface object) for creating a communication interface (for example, SSID, hereinafter referred to as interface object generation information), and a parameter value of the created interface object ( Hereinafter, it will be referred to as an object parameter). In this case, the ACS 31 transmits all information and parameter values for generating an interface object in step S306, and the 5G CPE 10 relays it so that the connection setting information is transmitted to the router 20. .

Meanwhile, the interface object may be created for each of nodes requiring 5G communication service. Here, a node requiring 5G communication service may mean each of a plurality of electronic devices connected to the router 20. In this case, communication interfaces for each node may be created after the router 20 is connected to the 5G base station 30 through a communication interface. To this end, connection setting information for generating a communication interface of each of the nodes may be transmitted to the router 20.

5 is an exemplary diagram illustrating an example in which connection setting information for generating a communication interface of each node is transmitted through the 5G CPE 10 according to an embodiment of the present invention in this case.

Referring to FIG. 5, as shown in FIGS. 3 and 4, the router 20 may establish a communication connection based on connection setting information received from the ACS 31 (communication interface creation, S500). And it is possible to initialize SSL (Secure Socet Layer) (S502). Then, information of nodes connected to the router 20 may be transmitted through the initialized SSL (S504). In addition, the ACS 31 may transmit a response message for the received information to the router 20 (S506).

Meanwhile, the ACS 31 that has transmitted the response message to the router 20 may transmit connection setting information according to a node connected to the router 20 (S508). In this case, the connection setting information transmitted from the ACS 31 may include both interface object generation information and object parameters for generating a communication interface of a corresponding node.

Then, the router 20 may add a connection setting for a 5G communication service based on the received connection setting information (S510). The connection setting added here may be a wide area network (WAN) point to point protocol (PPP) connection (WANPPPConnection). In addition, the router 20 may transmit a response message to the ACS 31 when the connection setting is completed (S512).

Then, each node connected to the router 20 may receive a service provided from the service provider 32 through a corresponding communication interface.

Meanwhile, unlike FIG. 5, the ACS 31 may transmit only interface object generation information, and the 5G CPE 10 may transmit parameters (object parameters) corresponding to the interface object to the router 20.

To this end, the ACS 31 can obtain information on the service to which the user has subscribed from the router device information received through the 5G CPE 10, and through the obtained information, the ACS 31 can obtain information on the service-providable nodes. You can get information about it. In addition, by transmitting information on the acquired nodes (information defined in the TR 181 protocol) to the 5G CPE 10, the 5G CPE 10 may provide object parameters to the router 20.

6 is an exemplary diagram illustrating another example in which connection setting information is transmitted through the 5G CPE 10 according to an embodiment of the present invention in this case.

Referring to FIG. 6, as shown in FIGS. 3 and 4, the router 20 may establish a communication connection based on the connection setting information received from the ACS 31 (communication interface creation, S600). And it is possible to initialize SSL (Secure Socet Layer) (S602). Then, information of nodes connected to the router 20 may be transmitted through the initialized SSL (S604). In addition, the ACS 31 may transmit a response message for the received information to the router 20 (S606).

Meanwhile, the ACS 31 that has transmitted the response message to the router 20 may transmit interface object generation information for generating a communication interface according to a node connected to the router 20 to the router 20 (S608).

Then, the interface object creation information may be transmitted to the router 20 via the 5G CPE 10. In this case, when the interface object generation information to be transmitted to the router 20 is received, the 5G CPE 10 may detect parameters of an object (interface object) corresponding to the received interface object generation information. In addition, the detected parameters, that is, object parameters may be transmitted to the router 20 together with the interface object generation information received from the ACS 31 (S610).

Then, the router 20 may add a connection setting for a 5G communication service based on the interface object generation information received from the ACS 31 and the object parameter received from the 5G CPE 10 (S612). Connection settings added here

It may be a Wide Area Networks (WAN) Point to Point Protocol (PPP) connection (WANPPPConnection). In addition, the router 20 may transmit a response message to the ACS 31 when the connection setting is completed (S614).

Then, each node connected to the router 20 may receive a service provided from the service provider 32 through a corresponding communication interface.

Meanwhile, in the above description, it is assumed that one router is connected to the 5G CPE 10 according to the embodiment of the present invention. However, two or more routers 20 may be connected to the 5G CPE 10. to be.

7 is an exemplary diagram illustrating a process of connecting a plurality of routers to the 5G CPE 10 according to an embodiment of the present invention.

Referring to FIG. 7, first, FIG. 7 (a) shows that in a state in which a communication interface for receiving a 5G communication service is formed in the first router 710, another router (the second router 720) is further connected. It is showing an example. In this case, as shown in (a) of FIG. 7, the second router 720 may transmit its own router device information to the first router 710 (700 ).

Meanwhile, the first router 710 receiving the router device information of the second router 720 may transmit the received router device information of the second router 720 to the 5G CPE 10. Then, the 5G CPE 10 may authenticate the second router 720 based on the received router device information. In addition, when authentication is performed, as shown in FIG. 7B, the received router device information of the second router 720 may be transmitted to the ACS 31 (702 ).

Then, the ACS 31 may transmit connection setting information for the second router 720 in response to the received router device information of the second router 720. In addition, the transmitted connection setting information may be received by the second router 720 via the 5G CPE 10 and the first router 710 as shown in (c) of FIG. 7 (704 ).

Then, the second router 720 may generate a communication interface for WAN PPP connection based on the received connection setting information, as shown in (d) of FIG. 7 (706 ). In addition, the electronic devices connected to the second router 720 are connected to the service provider through the generated communication interface, so that the electronic devices connected to the second router 720 can receive a service from the service provider connected to the 5G communication network. .

Meanwhile, as shown in FIG. 7, when the second router 720 is reconnected while the first router 710 is connected, the 5G CPE 10 may allow only one router to be connected. . For example, a communication service provider may set the 5G CPE 10 so that connection to a plurality of routers is prohibited, and in this case, only one router may be connected even if there are a plurality of routers.

When the connection of a plurality of routers is prohibited as described above, the controller 100 requests wireless communication from the second router 720 through the second communication unit 120 according to the creation of a new router, that is, a communication interface of the second router 720. If so, the MAC address of the previously connected router, that is, the first router 710 may be added to the connection prohibition list. Then, the first router 710 may be blocked so that a connection with the second communication unit 120 may not be established. Accordingly, only the second router 720 not added to the connection prohibition list may be connected through the second communication unit 120.

Meanwhile, the control unit 100 may initialize the connection prohibition list if none of the routers are connected. Therefore, even if the MAC address has been previously added to the connection prohibition list, the connection to the 5G CPE 10 can be made when a connection is made again without a connected router.

Meanwhile, if it is possible for a plurality of routers to be connected to the 5G CPE, the routers connected to the 5G CPE 10 may create a mesh network. In this case, the control unit 100 of the 5G CPE 10 may be connected to other routers through any one of the routers (hereinafter referred to as the main router) that creates the mesh network, and other routers through the main router. It can send data or receive data to routers. In this case, the main router may be the first router 710 of FIG. 7, and router device information of each router is transmitted to the ACS 31 through the main router 20 as described in FIG. 7. I can. In addition, connection setting information of the ACS 31 may be transmitted to other routers through the main router 20.

On the other hand, when the mesh network is formed through the routers, data is exchanged through the main router 20, and thus a bottleneck may occur when the performance of the main router 20 is poor. Accordingly, the controller 100 may determine and change the main router based on the capabilities of the routers forming the mesh network.

8 is an exemplary diagram illustrating an example in which the 5G CPE 10 according to an embodiment of the present invention is connected to a mesh network formed of a plurality of routers in this case.

First, referring to FIG. 8A, FIG. 8A illustrates an example in which the first router 810, the second router 820, and the third router 830 form the mesh network 800. It is showing.

In this case, the first router 810 may be a main router of the mesh network 800. Accordingly, data received from the 5G base station 30 through the first router 810 may be transmitted to the second router 820 or the third router 830, and the second router 820 or the third Data of the router 830 may be transmitted to the 5G base station 30 through the first router 810.

In this case, the 5G CPE 10 according to an embodiment of the present invention may collect performance information of each of the routers 810, 820, and 830 constituting the mesh network 800. To this end, the controller 100 of the 5G CPE 10 may measure the data transmission speed of each of the routers 810, 820, and 830 constituting the mesh network 800 at regular intervals. As an example, when the routers 810, 820, and 830 form a mesh network through a WiFi connection, the speed at which data is transmitted through the WiFi method may be collected as performance information of each of the routers 810, 820, and 830. have.

In this case, the collected performance information may be transmitted to a preset device. For example, the collected performance information may be transmitted to the user's mobile terminal, and accordingly, the user can check the performance of each of the routers 810, 820, and 830 constituting the mesh network 800.

Meanwhile, the controller 100 may determine a main router based on the collected performance information. For example, as a result of collecting the performance information, if the data transmission speed of the third router 830 is the best, the controller 100 may change the main router to the third router 830. In this case, the controller 100 may release the connection with the first router 810 and control the second communication unit 120 so that the third communication unit 830 is connected.

Then, as shown in (b) of FIG. 8, data received from the 5G base station 30 through the third router 830 may be transmitted to the first router 810 or the second router 820. In addition, data of the first router 810 or the second router 820 may be transmitted to the 5G base station 30 through the third router 830.

In this case, the controller 100 may determine the main router according to a preset statistical method, taking into account that the performance degradation may be a temporary phenomenon. Alternatively, the control unit 100 may change the main router to another router only when a deterioration in performance of more than a preset level occurs.

Meanwhile, as described above, the 5G CPE related to the present invention can detect the performance of other routers connected to the main router through the main router. Accordingly, the 5G CPE related to the present invention can determine whether other routers connected to the main router through the main router have failed, and if there is a router in which the failure has been detected, notification information for the router is preset to a device (e.g.: To the user's mobile terminal).

And according to the above description, the 5G CPE related to the present invention may be connected to a plurality of other routers through the main router. In this case, the number of routers that can be connected to the main router may be limited according to a service to which a subscriber, that is, a user subscribes.

In addition, the 5G CPE related to the present invention may obtain information on devices connected to each router through a connected router. And, based on the acquired device information, it is possible to check the data transmission speed required by the device. Then, the 5G CPE can determine whether the device is connected to a suitable router by comparing the data transmission speed required by the device and the data transmission speed provided by the router to which the device is currently connected.

As a result of the determination, if a suitable router is not connected, the 5G CPE may transmit notification information to notify the user. In addition, it is possible to detect the most suitable router to connect the device by checking the data transmission speed of each of the other connected routers. In addition, notification information including information on the detected router may be transmitted to the preset device and transmitted to the user.

Meanwhile, the recommendation of a router suitable for the device may be performed when a new device is connected or when a router setting is initialized.

The present invention described above can be implemented as a computer-readable code on a medium on which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAM, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc. There is also a carrier wave (for example, transmission over the Internet) also includes the implementation in the form of. In addition, the computer may include the control unit 100 of the 5G CPE 10. Therefore, the detailed description above should not be construed as restrictive in all respects and should be considered as illustrative.
