Home gateway device and home gateway system for remote power management and standby power management based on traffic information {Home gateway and home gateway system for managing standby power and romote power based on traffic information}

The present invention relates to a smartphone application that can check the network service usage status of devices connected to the home gateway from the outside, and send a power shutdown command when the service is not in use, and receives a standby power cutoff command from the smartphone. The present invention relates to a home gateway having a function of transmitting a power shutdown command of a corresponding device and shutting down standby power.

At present, Korea's IT level has developed rapidly, building the world's best information and communication infrastructure, exceeding 10 million high-speed Internet subscribers, and now the types of services using the Internet are gradually flowing into the home. The convergence of the information industry has resulted in the promotion of new services and the consequent development of hardware, software, content, and the development of Internet information appliances. To keep pace with these times, we strictly block broadband access and home networks, share various network types, and share information among devices to share services such as AV services, data and network device sharing services, and home appliance control services in the home. And a home gateway system capable of control has become indispensable.

In addition, the network technology that enables access to the network anywhere in the home by using wired and wireless services has been continuously developed, thereby laying the foundation for the realization of the home network.

The home network centered on the home gateway is the network responsible for the final stage of the information infrastructure following the national backbone network and subscriber access network.It is essential for the early establishment of the information infrastructure, which is the foundation of the knowledge and information society under the Cyber Korea 21 policy. Field. It is possible to establish a foundation for strengthening welfare by establishing an environment that enables easy access to telemedicine and distance education through home gateways, and to improve public welfare by lowering information appliances and providing various information and communication services. In addition, by providing the opportunity for housewives and elderly people who had difficulty using PCs to join the informatization process more easily through familiar home appliances, they can contribute to the acceleration of information distribution speed through the daily use of Internet information appliances. have.

In the transformation of various communication networks, the home network is the end of the information infrastructure where users connect directly to the communication networks and use various network services, and play a role as a thread in the human circulation.
