Hereinafter, the present invention will be described in detail with reference to the drawings.

Referring to FIG. 2, the Internet binary access system according to the present invention is composed of a customer premises device 100, a network information management server 200, and a subscriber information server 300. Provides a dual Internet connection between a broadband network and a mobile communication network for a plurality of in-house user devices 10. In this case, the term'inside' in the present specification is not limited to a home, but generally refers to a space divided from the outside, such as a store or an office.

In the present invention, the customer premises device 100 is a device installed in a subscriber premises of an Internet access service to provide a broadband network (Internet) access path to one or more in-house user devices 10. For example, it can be implemented as an Internet router and provides a wireless LAN (Wi-Fi) or a wired LAN (LAN).

The network information management server 200 is preferably a server device operated by a communication service company, and a communication company server (Mido It is a device that manages access information, preferably IP address information, of a series of communication devices (eg, gateways) included in the access route to (city).

The subscriber information server 300 is also preferably a server device operated by a communication service company, and manages information on a plurality of subscribers who have subscribed to the Internet access service. In general, communication service companies manage various information about subscribers for customer management and billing purposes. For example, user ID, subscriber name, subscriber contact information, subscriber postal address, and installed in the subscriber's premises. Device identification information of the in-house user device 10, that is, CPE identification information (MAC Address of CPE), billing information of service charges (eg, credit card number), and the like.

Through this configuration, in the Internet binary access system according to the present invention, the customer premises device 100 switches and controls the network access path between the broadband network and the mobile communication network in response to the communication situation of the communication equipment of the communication service company. Even when the operation of the wired Internet communication network becomes difficult or impossible due to an excessive decrease in the packet processing speed of communication equipment or a fire in a communication port through such an Internet dualized connection, the in-house user equipment 10 is connected to the broadband network (Internet). It can keep the connection quality to some extent stable.

First, the network information management server 200 according to the present invention manages a database of IP addresses of a series of communication devices included in an access path from each subscriber location to a communication service provider server (not shown) for a plurality of subscriber address locations. In Figure 3, the network information management server 200 is a database of the IP addresses of gateways included in the access route from each address to the telecommunication company server for two address locations, 884-3 Seongnam-daero, Bundang-gu, Seongnam-si and 1620 Bongyeong-ro, Yeongtong-gu, Suwon-si. It showed management. In this specification, the IP list of communication devices included in the access path is referred to as'communication device transit information'. For example, the information via communication equipment for the address '884-3 Seongnam-daero, Bundang-gu, Seongnam-si' is {193.23.27.31, 193.25.27.21, 193.15.24.29 }.

Next, preferably, when the installation staff of the communication service company visits the home of a new subscriber and performs the initial Internet opening operation, the customer's premises device 100 registers a user for the corresponding subscriber with the subscriber information server 300. Transmit information. At this time, the user subscription information is composed of a user ID, subscriber address information, and CPE identification information (MAC Address).

In response, the subscriber information server 300 allocates and provides an IP address to the customer premises device 100 by, for example, DHCP (Dynamic Host Configuration Protocol). In addition, the subscriber information server 300 transmits user subscription information for a corresponding subscriber to the network information management server 200. Preferably, this process is performed in Internet opening work for new subscribers.

The network information management server 200 inquires the subscriber location information included in the user subscription information provided from the subscriber information server 300, for example, the address '884-3 Seongnam-daero, Bundang-gu, Seongnam-si' in the database. Information via communication equipment for the device 100, such as {193.23.27.31, 193.25.27.21, 193.15.24.29}, is obtained from the database.

The network information management server 200 transmits the acquired communication equipment route information to the customer premises device 100, and accordingly, the customer premises device 100 transmits the communication equipment route information for itself from the network information management server 200. It receives and stores it internally. Through this, each customer's premises device 100 can identify IP information of communication devices of a communication service company that it must pass through to access the Internet. On the other hand, in order to prevent hacking, it is preferable that the customer premises device 100 encrypts and stores information via communication equipment as an internal private key.

First, an Internet access failure occurs in the in-house user device 10. For example, repeated failures to connect to a site on a laptop computer.

In this case, the customer's premises device 100 also detects an Internet access failure to the communication equipment of the communication company. For example, when a normal TCP request packet is sent from the in-house user device 10 to the external Internet, and a corresponding TCP response packet is not received, the customer in-house device 100 may detect an Internet connection failure. Alternatively, if IP packets continuously go out to the external Internet, but there are too few or no IP packets coming from the external Internet, the customer's premises device 100 may detect that the current Internet access is in a state of failure.

In the case of identifying an Internet access failure as described above, the customer's premises device 100 is provided with information via communication equipment stored in the above, for example, a series of communication equipment IP addresses belonging to {193.23.27.31, 193.25.27.21, 193.15.24.29 }. Responsiveness tests are performed sequentially. For example, as shown in FIG. 4, the customer premises device 100 sequentially performs a PING test for each IP address, that is, 193.23.27.31, 193.25.27.21, and 193.15.24.29, and obtains the result.

Then, the customer premises device 100 identifies a communication equipment failure based on the result of the responsiveness test. In the example of FIG. 4, the PING test for Gateway 1 was successful, while the PING test for Gateways 2 and 3 failed. At this time, it is desirable to increase the reliability of the test result by repeatedly performing the PING test several times. Based on the PING test result, the customer premises device 100 may identify that a failure has occurred in Gateway 2. Such a failure may be caused by a failure of the gateway device itself or a problem in communication between the gateways 1 and 2, but since there is no real benefit of classification, it is collectively referred to as'communication equipment failure' in this specification.

When a communication equipment failure is identified as described above, the customer premises device 100 performs access switching to a base station of a mobile communication network by an internal mobile communication module (eg, a 5G module) to restore or maintain the connectivity of the Internet service.

In addition, the customer premises device 100 transmits the result of the responsiveness test to an external service management server 400 operated by a communication service company. At this time, it is preferable to use the Internet connection of the mobile communication network. In this case, when a problem occurs in the communication equipment, the responsiveness test result will be simultaneously provided to the service management server 400 from a plurality of customer premises devices 100. From this, the communication service company can identify information on the fact that a failure has occurred in the communication equipment of the Internet service and the location of the failure.
