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.
Claims5
A method for establishing Wi-Fi Direct Services (WFDS) communication by a first device having a processor and a transceiver, the method comprising:
- determining, by the first device, one or more potential services capable of being sought through a Near Field Communication (NFC) touch based on executing a service or an application by the first device, before the NFC touch occurs;
- receiving, by the first device, a handover select message from a second device via a NFC channel after the NFC touch occurs;
- determining, by the first device, whether the one or more potential services are matched to information parsed from the handover select message;
- and
- when there is a matched service between the one or more potential services and the information parsed from the handover select message, establishing, by the first device, a Wi-Fi interface with the second device and initiating the matched service with the second device,
- wherein the handover select message contains information indicating one or more services supportable by the second device.

A first device for establishing Wi-Fi Direct Services (WFDS) communication, the first device comprising:
- a transceiver;
- and
- a processor,
- wherein the processor determines one or more potential services capable of being sought through a Near Field Communication (NFC) touch based on executing a service or an application by the first device, before the NFC touch occurs,
- wherein the processor receives a handover select message from a second device via a NFC channel after the NFC touch occurs by controlling the transceiver,
- wherein the processor determines whether the one or more potential services are matched to information parsed from the handover select message,
- wherein when there is a matched service between the one or more potential services and the information parsed from the handover select message, the processor establishes Wi-Fi interface with the second device and initiating the matched service, and
- wherein the handover select message contains information indicating one or more services supportable by the second device.
