Abstract: Device and method for remote device profile management/identification for intelligent discovery are disclosed. A remote device profile management method for service interworking may include receiving a request to register a device profile of a local device for a cloud network, generating a regular profile identification (ID) for the device profile, registering a record including the regular profile ID along with ID and connection information of a device registry in which the local device is registered, and registering a record including the regular profile ID and the device profile.

Abstract: Disclosed is a method of identifying an Internet of things (IoT) service group based on an object identifier, the method including retrieving a first group identifier of a first service group corresponding to a first object identifier in response to the first object identifier transmitted through a uniform resource identifier (URI) corresponding to the first object identifier, identifying services include in the first service group using the first group identifier, and transmitting information of the identifier services. Here, the first service group may be a service group requested from a user.

Abstract: A service profile discovery and connection management method for interworking with an IoT device. According to example embodiments, a remote device discovery method for service interworking includes an operation of receiving, from a local device, a discovery profile request message for discovering a device profile of a target local device for service interworking, an operation of searching for a service profile based on a first device profile of the local device included in the discovery profile request message, an operation of searching for, as the device profile of the target local device, a second device profile including one or more functions excluding a function of the local device by matching the searched service profile with device profiles stored in a database, and an operation of transmitting a discovery profile response message including an ID of the second device profile.

Abstract: Disclosed is a method and apparatus for configuring a network based on near-field communication (NFC), the method including determining whether NFC terminals access in a multi-hop range or a single hop range; classifying roles of the NFC terminals based on connections between the NFC terminals and neighboring communication terminals when the NFC terminals access in the multi-hop range; and classifying roles of the NFC terminals based on properties when the NFC terminals access in the single hop range.

Abstract: Disclosed are a self-organizing network (SON) method in an Internet of things (IoT) environment, and an apparatus performing the SON method. The SON method includes receiving neighboring device information from at least one neighboring IoT device of an IoT device, updating device information of the IoT device based on the received neighboring device information, and determining whether the IoT device is a coordinator candidate based on at least one of a number of network interfaces, a number of neighbor links connected to the network interfaces, or a ratio of remaining energy, which is included in the device information.
