GATEWAY AND CONTROL METHOD THEREOF

The present invention relates to a gateway and a control method thereof.

Currently, the Internet of Things (IoT) service is provided through the IoT service platform established by telecommunication companies and companies. The communication company or company discloses a service API (Application Program Interface) for a third party service provider (hereinafter referred to as a service provider), and a third party service provider provides a service platform To provide IoT service.

In order to provide IoT service, not only IoT device but also IoT gateway needs to be compatible with the corresponding service platform. In other words, in order to provide a desired IoT service, a compatible IoT gateway is needed for the corresponding IoT service platform.

In this service platform environment, when a user joins a specific service provider and provides IoT service, the user can only use the IoT gateway and the IoT device compatible with the corresponding service platform. Accordingly, the user can only receive the IoT service provided by the specific IoT service platform, and the IoT device and the device manufacturer are also limited. IoT devices that can be used for general purpose IoT services are virtually impossible because they must be compatible with all IoT service platforms. Therefore, when a user wishes to receive another IoT service, a new IoT gateway and IoT device must be installed.

A problem to be solved by the present invention is to provide a gateway device capable of selecting a desired service provider according to an IoT device or an IoT device manufacturer through a single gateway and a control method thereof.

A gateway for providing a service between a destination Internet device and a service control server according to an embodiment of the present invention includes: a communication module for wirelessly communicating with the destination Internet device to receive device information and service connection information from the destination Internet device; An application program management module for downloading a gateway application program stored in the service control server using the device information and service connection information; And a service session management module for creating a service session when a service request is generated from either the object Internet device or the service control server, and delivering the service request to the gateway application program.

Here, the device information includes an identifier of the Internet appliance, and the service connection information includes an IP address of the service control server and a service identifier of the service.

The service session management module receives a service identifier and service data corresponding to the service request from at least one of the Internet appliance and the service control server, and transmits the service identifier to the gateway application program corresponding to the service identifier And transmits the data.

Also, the device information and service connection information are information stored in a short-range wireless communication tag attached to the object Internet device, and the communication module receives the device information and service connection information read from the smart device. The communication module adds the node of the new object Internet device to register the new object Internet device when the object Internet device is newly installed.

A method of controlling a gateway for providing a service between a plurality of Internet browsing apparatuses and a plurality of service control servers for managing each of the plurality of Internet browsing apparatuses according to an embodiment of the present invention, Receiving connection information; Accessing a service control server corresponding to each of the plurality of object Internet devices using the device information and the service connection information; Downloading the gateway application program from the service control server; And generating a service session when a service request is generated from at least one of the object Internet appliance and the service control server, and delivering the service request to the gateway application program.

Here, the device information includes an identifier of the Internet appliance, and the service connection information includes an IP address of the service control server and a service identifier of the service.

In addition, the step of delivering the service request to the gateway application program may include receiving a service identifier and service data corresponding to the service request from one of the Internet appliance and the service control server; And transmitting the service data to the gateway application corresponding to the service identifier.

The device information and the service connection information are information received in contact with the short range wireless tag attached to the Internet appliance. Also, the device information and the service connection information are information read by the smart device from the short distance wireless tag attached to the object Internet device.

According to the embodiment of the present invention, a single gateway is not limited to a specific service platform, and various services can be provided in cooperation with a plurality of service providers. In addition, various types of services can be provided by using IoT devices that are interworked with a plurality of service platforms in a home where services are to be provided.

And, in the production of IoT devices, it is possible to produce general-purpose IoT devices that do not depend on a specific service platform. In addition, the service provider can operate the service control server alone or on a small scale without depending on the specific service platform.

The IoT device manufacturer can directly provide the service irrespective of the specific gateway, and the gateway application can be directly implemented by the service provider, thereby adding various functions such as a proxy function to the gateway.
