Abstract:
The present invention relates to a wireless communication system, and a method for executing a service search and an advertisement. To this end, the method by which a first wireless device performs a service search comprises the steps of: transmitting a probe request frame which includes a hash value; receiving, from a second wireless device, a probe response frame which includes first service information corresponding to the hash value; transmitting a service search request frame which includes a search word to the second wireless device; and receiving, from the second wireless device, a service search response frame which includes second service information corresponding to the search word, wherein if a preset symbol is attached to the search word, the second service information can include at least one service name having the search word as a prefix.
Abstract:
A compressor according to the present disclosure may include a container; a drive motor provided in the container; a crankshaft coupled to a rotor of the drive motor; a first scroll coupled to the crankshaft to receive a rotational force of the drive motor to perform an orbiting movement; a second scroll coupled to the first scroll to form a first compression unit and a second compression unit along with the first scroll; and a vane provided in the first scroll or second scroll to be brought into contact with the other side scroll to form the second compression unit, wherein the first compression unit is carried out in a scroll compression mode and the second compression unit is carried out in a rotary compression mode.
Abstract:
Disclosed according to one embodiment of the present invention is a method whereby a management device, which enables coexistence of television white space (TVWS) devices in a TVWS, sends a server a request for the selection of a master management device, the method comprising the steps of: determining whether a trigger condition for the process of selecting the master management device is satisfied; judging the management device as a candidate slave management device, and the other management devices as candidate master management devices, provided that the trigger condition is satisfied; and initiating the process for selecting the master management device, wherein the trigger condition may be based on the load balance parameter or geographical coverage parameter of the management device.
Abstract:
The present invention relates to a wireless communication system and more particularly, to a method for performing connection setting for Wi-Fi direct services communication and a device therefor, the method comprising a step of performing device discovery between two devices through an NFC touch.
Abstract:
Provided is a method for registering TVWS devices for coexistence of television white space (TVWS) devices in a television white space (TVWS), the method performed a server and comprising receiving a registration request message for registration or update registration of at least one TVWS device from at least one management device; performing the registration or update registration of at least one TVWS device; and in response to the registration request message, transmitting a registration response message to the at least one management device, wherein the registration response message includes at least one of an identifier field of an interface device connected to the at least one TVWS device, a status field indicating a result of the registration or the update registration, and a reason field indicating a reason why the registration or the update registration is failed if the registration or the update registration is failed.
Abstract:
A device and method for performing inter-device communication are disclosed. An inter-device communication method of a first device includes searching for a second device supporting inter-device communication, receiving network information from the searched second device, and determining that one of the first and second devices is a group owner based on the received network information of the second device and network information of the first device. The network information includes at least one selected from among type information indicating a server device or a client device, network support information, network necessity information, and network setting information.
