The following embodiments relate to a method and apparatus for a smart home service, and more particularly, to a method and apparatus for a smart home service to which a virtual home gateway is applied.
“Connected home” indicates that a variety of in-house apparatuses equipped with a network function, including electronic products, are connected to each other. “Connected home” has been gradually expanded all over the world.
Communication providers, electronic product manufacturers, Internet portals, and the like provide a connected service, such as application interaction or content interaction between connected apparatuses, for example. The above companies are recruiting customers of the service and are trying to increase revenues obtained from the service. For example, in European Countries, a gateway combined with an Internet protocol television (IPTV), a voice over Internet protocol (VoIP), and the like, has been placed on a large scale.
A gateway is an apparatus that functions as a bridge positioned between an external network and a home network to thereby connect the external network and the home network. The external network may be an Internet network or a wideband communication network. The home network may be a network constructed at home.
Gateway technology has started at a level of providing an Internet sharing function. In the gateway technology, a function of directly providing a media service, a home automatic service, and the like, or a function that enables such services to be readily provided from other apparatuses may be gradually added.
“Smart home” indicates an intelligent in-house living environment or an intelligent residential space. “Smart home” is in pursuit of an intelligent living environment, an environment-friendly residential life, and innovation of quality of life by realizing a ubiquitous environment at home based on wired/wireless communication and digital information appliances. The ubiquitous environment indicates an environment in which computing is provided without restrictions on a time, an occasion, and a device, by employing home networking and Internet information home appliances.
“Home automation” may indicate automation of house life and housekeeping life. Also, a home automation system may indicate a system to automate management of housekeeping work. The management of housekeeping work may be automated based on an electronic device, an automatic device, and the like. A home automation service may include controlling and monitoring an in-house device, managing a user and a terminal, and the like.
Cloud computing is a computing style that provides functions associated with information technology (IT) in a service form. An existing computing environment depends on independent hardware performance of each terminal. In a cloud computing environment, resources of computers present at physically different positions may be integrated through virtualization technology and the integrated resource may be provided.
A home gateway is an apparatus that functions as a bridge positioned between an external network and a home network to thereby connect the external network and the home network. The external network may be an Internet network or a wideband communication network. The home network may be a network constructed at home. A plurality of terminals may be present in the home network.
In a general home gateway, following issues may arise.
For example, a gateway is equipped with all of the communication protocols and thus, every time a new protocol is added to a home gateway, every time a function of a protocol installed in the home gateway is modified or changed, or every time firmware of the home gateway needs to be changed, the home gateway needs to be updated. Since the home gateway is installed at home, an operator may need to visit in person a user's house in which the home gateway is installed and to process an operation in order to update the home gateway or to add a terminal.
Also, all of the home automation services are performed through the home gateway. Accordingly, when a variety of error situations occur, countermeasures for the corresponding error situations need to be performed through the home gateway. Also, when an error situation occurs in the home gateway, it may be difficult to cope with the error situation. Since the home gateway manages and controls all of the in-house terminals, great load may be applied to the home gateway. Accordingly, managing and controlling of a terminal may be constrained based on performance of the home gateway.
All of the data associated with an operation of the home gateway is stored and processed within a database or a storage of the home gateway. Accordingly, due to limited capacity of the home gateway, it may become difficult to process a large amount of data.
With a variety of home automation services or commercialization of a smart home service, there is a need to apply technology about a virtual terminal and a virtual home gateway using cloud computing to the above services.
