FIELD OF THE INVENTION [0001] The present invention relates to an Internet control method using a home gateway,

BACKGROUND OF THE INVENTION 1. Field of the Invention [

More specifically, it is possible to utilize home gateways to support mutual interoperability between multiple platforms, thereby enabling smart home appliances, Internet appliances based on smart Internet, and wellness / healthcare services, In addition, it can provide various services such as activation of various services through smart home appliance interlocking, detection of malfunctions of smart home appliances, energy efficiency, monitoring of home situation, utilization as a healthcare device in a hospital by utilizing such a home gateway And more particularly, to an Internet control method for objects.

Home network technology, which is generally representative of digital convergence, is emerging as a cutting-edge item in the communication and electronics industries.

The home network is a key component of the 'digital home', which is a future home environment where information appliances in the home are connected to the network and services are provided regardless of the device, time, and place. It is considered as a representative service of digital convergence (convergence) that can utilize various IT devices based on high-speed infrastructure to enable remote education, entertainment, healthcare, and information appliance control.

Especially, home network technology that can automate household chores from the outside through wireless or internet has been developed since the late 1990s by the United States and Japan as one of the future technologies, and companies such as Intel and Microsoft are developing their own Technology as the world's standard home network technology.

In recent years, domestic telecom companies and electronics industry have been developing technology in this field, and are trying to compete in technology complex by attempting a rudimentary type of home network in apartment complexes recently moved. Especially, related technology developed by some companies in Korea has been recognized as a technology standard of the United States and proves that domestic technology has reached world-class level.

When you set up a home network, you can check whether the person pressing the doorbell and the end of the laundry is in the room. In the home network system, the user can monitor his or her home from the outside as if adjusting the TV with a remote control at home using a PDA or mobile phone. You can adjust the house temperature and cook rice from the outside. You can also receive a medical checkup automatically.

With the development of the Internet and sensors in the year 2010, these home network systems are evolving to the concept of Internet of Things, and various devices for Internet-enabled devices are being developed in Korea to activate Internet services.

However, due to the problem of standardized home network, most of them are acting as communication / network connection devices such as Bluetooth and WiFi, and have not succeeded in the market.

Therefore, such a market is expected to be very successful in the market if the Internet platform / standard of things is equipped.

Examples of the domestic R & D situation in the domestic home network are as follows.

ETRI is known to have technology to link home appliances to a limited range by developing Bluetooth, WiFi interworking device for interfacing different devices for smart home in 2014, and DLNA interworking technology as home network standard in early 2000.

In Humax, home gateway server (HGS) supports three services of broadcasting, wired / wireless internet, and voice telephony (VoIP) in one set-top box. It is a home network composed of real time broadcasting, video, music, It is sharing multimedia contents.

At LG Electronics It is known that it is conducting research for home appliance integration such as launching a broadband TV that can make video, voice call and video conference via the Internet in cooperation with Skype and launching Home Chat.

Samsung Electronics develops its own smart home protocol and performs interworking with its own developed products. In addition, Zwave is known to be active in the development of Internet platform for objects such as participating in OIC.

In SKT It is known that the framework between the provider server and the home gateway is being developed and standardized, and it is being expanded to the development work on a framework that can gradually accommodate the services developed in the heterogeneous service domain.

On a bit computer AllJoyn has acquired OneM2M platform technology / interworking technology, secured various security / privacy technologies, and intelligent cognitive framework technology, and jointly developed the Internet of Things Internet / Protocol-based smart home interworking, smart mirror interworking, weight scale interworking, and SNS interworking.

Regarding domestic market size and import / export situation, according to a survey by the Korea Smart Home Industry Association, the domestic smart home market size is 6,890.8 billion won in 2013, an increase of 11.8% over the previous year (6,146.1 billion won) Smart TV and home entertainment accounted for half of the market with 3.654 trillion won (53.0%), while smart convergence home appliances will be followed by 2.246 trillion won (32.6%). There is one.

Meanwhile, the global smart home market in 2013 is estimated at $ 48 billion (about 49 trillion won), which is expected to grow at an average annual rate of 19%, reaching $ 115 billion by 2019. Strategy Analytics estimates that at least one smart home system will be used in about 224 million households by 2019, with the largest markets in the smart home sector expected to expand rapidly in the US and Europe and China, , Samsung Electronics, AT & T, Deutsche Telekom, and Amazon are also spurring smart home service and platform launches.

Also, the importance of software platform is increasing in the smart home market. Google is pushing for a smart home ecosystem based on Android-based platform openness. Following the acquisition of Nestlab, Google has released its core smart home platform and is planning to work with Google Now to grow it into a core service in the future. Apple also unveiled its smart home platform 'HomeKit' and is partnering with home appliances and chipset companies such as Haier, Philips, Osram, Texas Instruments and Broadcom to provide devices for smart home.

On the other hand, security is one of the important factors related to the construction of the Internet system of things.

Therefore, the safety requirements of the entire system are increasing as well as the functions of the gateway located at the center of the object Internet.

Current Internet products have serious security vulnerabilities.
