A service discovery method in a wireless LAN system according to one embodiment of the present invention can comprise: transmitting, by a request device, a service discovery request frame to a response device; and receiving, by the request device, a service discovery response frame, which comprises service information of the response device and service information of each of one or more other devices, from the response device. The one or more other devices can comprise a device which does not belong to the same group as the response device.
Abstract:
An Internet of Things (IoT) device may transmit, to a Blockchain Node, a registration request signal including a public key certificate of the IoT device and a universally unique identifier (UUID) of the IoT device. The IoT device may receive, from the Blockchain Node, a first certification identifier (ID) for the IoT device, wherein the first Certification ID is a newly generated block. The IoT device may receive a first encrypted signal from an onboarding tool (OBT), wherein the encrypted signal includes a second certification ID of the OBT and encrypted information being encrypted based on a private key of the OBT. And, the IoT device may transmit, to the Blockchain Node, a verification request signal including the second certification ID of the OBT.
Abstract:
The present specification may provide a method for a sink device receiving a streaming from a source device in a wireless communication system. In this regard, the method for receiving streaming may comprise the steps of: receiving from the source device streaming over a first transport protocol; transmitting to the source device a first message including information regarding a transport protocol of the sink device when the first transport protocol connection is disconnected; receiving from the source device a second message including information regarding a transport protocol of the source device; and receiving from the source device the streaming over one of the first transport protocol and a second transport protocol.
Abstract:
