Abstract: Method and device for discovering a service are provided. A responding device receives a service request frame including a first service identifier indicating a service queried by the requesting device. The responding device transmits a service response frame to indicate that the queried service is currently not available and a service announce frame follows on. The responding device determines whether the queried service is accepted or not during a pre-defined time after transmitting the service response frame.

Abstract: Provided is a communication method by a station (STA) that operates in a power safe mode in a wireless LAN system. The method comprises: transmitting a probe request frame to an access point (AP), wherein the probe request frame includes system information identification information for identifying system information acquired by the STA; and receiving a probe response frame as a response to the probe request frame from the AP. The probe response frame includes a time stamp value related to the point of time of transmitting the probe response frame, and if it is determined, based on the system information identification information, that updated information which is not included in said acquired system information exists, the probe response frame further includes said updated information. Also provided is a communication method by an access point (AP) in a wireless LAN system. The method comprises: receiving a probe request frame from a station (STA), wherein the probe request frame includes information related to a wake-up duration time that is a time period in which the STA operates in an awake state; and transmitting a probe response frame to the STA as a response to the probe request frame. The probe response frame is transmitted within said wake-up duration time.
