A method for registering a wireless device by a terminal in a wireless communication system is provided. The method includes obtaining connection information for the wireless device by scanning a recognition code of the wireless device in a first mode, transitioning to a second mode based on the connection information and receiving a connection request from the wireless device, performing a connection operation to the wireless device to transmit network access information to the wireless device, and transitioning to the first mode, and registering the wireless device upon detecting connection of the wireless device to a network in the first mode.

Method and apparatus for registering wireless device in wireless communication system

Disclosed is a technology for a sensor network, machine to machine (M2M), machine type communication (MTC), and internet of things (IoT). The present disclosure can be used for intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the technology. A method of controlling a visitor's call by a first terminal in a home network system includes: reading home information pre-stored in the communication module when communication with a communication module installed inside the home is possible; transmitting a visit request message including the home information and identification information of the first terminal to the smart home server or a at least on second terminal from among a plurality of second terminals; and communicating with the at least one second terminal when at least one of the plurality of second terminals accepts communication with the first terminal.

Method and apparatus for controlling visitor call in home network system

A gateway (GW) in a wireless communication system, according to the present disclosure is provided. The GW generates self-signed authentication information, allocates the self-signed authentication information to at least one device, transmits a registration request message for requesting registration of the at least one device to a server if a certificate channel with the at least one device is generated based on the self-signed authentication information, and transmits certificate information for the at least one device to the at least one device if the certificate information for the at least one device is received from the server.

Method and device for registering and certifying device in wireless communication system

A method for issuing an access token of a device by a control point is provided. The method includes transmitting a search request message to the device, receiving, from the device, a search response message including first information indicating a type of the device, requesting access token issuance to the device using first information and second information, the second information including additional information about the device, and receiving the access token from the device. The second information may include model information about the device.

Method and apparatus for issuing and getting access token of device

Provided are a light emitting device including a transparent electrode having high transmittance with respect to light in a UV wavelength range as well as in a visible wavelength range and good ohmic contact characteristic with respect to a semiconductor layer and and a method of manufacturing the light emitting device. A transparent electrode of a light emitting device is formed by using a resistance change material which has high transmittance with respect to light in a UV wavelength range and of which resistance state is to be changed from a high resistance state into a low resistance state due to conducting filaments, which current can flow through, formed in the material if a voltage exceeding a threshold voltage inherent in a material applied to the material, so that it is possible to obtain high transmittance with respect to light in a UV wavelength range.

Light emitting device having transparent electrode and method of manufacturing light emitting device

Provided is a light receiving device including a transparent electrode and a method of manufacturing the light receiving device. A transparent electrode is formed so as to be in contact with a photoelectric conversion layer which absorbs light to generate electric energy, and the transparent electrode is formed by using a resistance change material which has high transmittance with respect to light in the entire wavelength range and of which resistance state is to be changed from a high resistance state into a low resistance state if a voltage exceeding a threshold voltage inherent in the resistance change material so that conducting filaments are formed in the transparent electrode. Accordingly, since the transparent electrode has high transmittance characteristic with respect to the light in the entire wavelength range and high conductivity characteristic, the light receiving device also has high photoelectric conversion efficiency and good electric characteristics.

Light receiving device including transparent electrode and method of manufacturing light receiving device

A method for sending a service by a first gateway (GW) among multiple GWs includes, upon reception of a request for a service from a terminal, determining whether the first GW is able to provide the service, detecting a second GW that is able to provide the service requested by the terminal among the multiple GWs based on GW management information that includes respective service information regarding services that the multiple GWs are able to provide, if the first GW is not able to provide the service, requesting the second GW to provide the service requested by the terminal, and upon reception of the service from the second GW, forwarding the service to the terminal. The other embodiments, including a gateway and a terminal are also disclosed.

Method and apparatus for transmitting and receiving service in wireless communication system

Provided is a vertical type light emitting device and a method of manufacturing the same. A transparent electrode having high transmittance with respect to light in the entire range and constructed by using a resistance change material of which resistance state is to be changed from a high resistance state to a low resistance state if a voltage exceeding a threshold voltage inherent in a material is applied so that conducting filaments are formed is formed between an electrode pad and a semiconductor layer of a light emitting device. The transparent electrode has high transmittance with respect to the light in a UV wavelength range as well as in a visible wavelength range generated in the light emitting device. Since the conductivity of the transparent electrode is heightened due to the formation of the conducting filaments, the transparent electrode has good ohmic contact characteristic with respect to a semiconductor layer.
