Embodiment approach 1

[0109] Implementation 1: No specific seeker exists

Embodiment approach 1-1

[0110] Embodiment 1-1: Two devices support NFC

[0111] Figure 7 is a diagram illustrating an example of a WFDS connection procedure using NFC switching employed by the present invention.

[0112] Such as Figure 7 As shown, both device A and device B support Wi-Fi and NFC. In the example shown, neither device is a seeker seeking service. In each device, the service entity can notify the ASP entity of the WFDS services that the device can support. The ASP entity can configure advertising services in the Wi-Fi module and the NFC module. The ASP entity may simultaneously or sequentially configure advertisement service information in the Wi-Fi module and the NFC module, and define the service based on a specific command (eg, org.wi-fi.wfds.send.rx).

[0113] Since neither device is a service seeker, the handover process can only be initiated after an NFC contact has occurred. Here, the NFC contact may be a contact or a proximity contact. For NFC contacts between two devic...

Embodiment approach 1-2

[0124] Embodiment 1-2: Connection between WFDS equipment and non-WFDS equipment

[0125] Figure 8 is a diagram illustrating another example of a WFDS connection procedure using NFC switching employed by the present invention.

[0126] Such as Figure 8As shown, assume that device A supports Wi-Fi and NFC and WFDS, but device B does not support WFDS. Hereinafter, transmission of a handover request message from device A to device B performed on this assumption will be described. as reference Figure 7 As mentioned above, the device A can send the service that the service entity can provide to the ASP entity, and the ASP can provide to the Wi-Fi and NFC entities respectively.

[0127] After the NFC contact occurs, device A transmits a handover request message to device B (S810). The handover request message may include: P2P device information related to device A, and WFDS service hash information related to device A.

[0128] In response to the handover request message, th...

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.

Description

technical field [0001] The present disclosure relates to a wireless communication system, and more particularly, to a Wi-Fi Direct Service (WFDS: Wi-Fi Direct Services) communication method and device thereof using NFC technology. More specifically, the present invention relates to a method for establishing a connection through NFC contact and a device thereof. Background technique [0002] Wireless communication systems are widely deployed to provide various types of communication services such as voice and data services. Typically, these communication systems are multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Examples of multiple-access systems include: Code Division Multiple Access (CDMA) systems, Frequency Division Multiple Access (FDMA) systems, Time Division Multiple Access (TDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, and Single ...
