Herein, the system for transferring content may include a coupling controller configured to identify a user equipment in accordance with a content transfer request and to perform coupling with the identified user equipment, and a content transfer unit configured to transmit content to the user equipment or to receive content from the user equipment, when coupling is completed.

Abstract: Disclosed is a method and system for re-directing a dynamic instance hosting service of a virtual object. The dynamic instance hosting service re-directing system may include a spatial information controller configured to determine whether an instance of an Internet of Things (IoT) device is movable based on spatial information of the IoT device using an instance hosting function; and an instance resource controller configured to manage available instance resources associated with the IoT device and an external service for an instance movement of the IoT device.

Abstract: An access point and a method for controlling an IoT (Internet of Things) device, using the access point. The method includes receiving a request for a service list from a user terminal through a smart access point communication with one or more IoT devices provided in one space; providing a list of virtual objects which are able to be provided out of virtual objects corresponding to the one or more IoT devices to the user terminal as the service list; receiving a control service request generated from the service list of the user terminal; identifying an IoT device corresponding to the control service request and requesting the identified IoT device for IoT control; and renewing a state of a virtual object corresponding to the identified IoT device based on a response of the identified IoT device and transmitting information on the state renewal to the user terminal.

Abstract: A method and system for providing a service based on space are disclosed herein. The method includes registering multiple smart access points respectively included in multiple spaces—each of the access points are connected to at least one Internet of Things (IoT) device that is further included in the corresponding space, providing first service control information to a first smart access point, in accordance with a request of the first smart access point, the first smart access point being accessed by a terminal of a user, among multiple access points, and providing second service control information to a second smart access point in accordance with a request of the second smart access point, when the terminal of the user accesses the second smart access point, among the multiple access points, and when the second smart access point recognizes a movement of the user.

Abstract: A service system in an IoT environment is provided. The service system includes an instance manager configured to manage generation and operation of an instance for a virtual object corresponding to an IoT device. The instance manager includes an instance pool configured to pool the instance, a message router configured to filter a data stream according to the instance and to transmit the filtered result value together with the data stream, and an instance lifecycle manager configured to reuse the instance pooled in the instance pool according to the filtered result value or to skip calling of an instance according to the data stream.

Abstract: A service method and a system for managing a transaction using application properties are provided. The service system includes a cloud-based virtual object transaction manager. The virtual object transaction manager includes when a virtual object of an IoT device is generated, an application program interface (API) registering unit configured to register an interface provided form the virtual object as an API format and an API use permission managing unit configured to manage use permission of an API according to each virtual object of an IoT device registered on a cloud service.
