A device discovery method and apparatus of a Wi-Fi Peer-to-Peer (P2P) device for improving connection compatibility with legacy devices are provided. The method includes receiving a command for executing a modified P2P device discovery mode, configuring the Wi-Fi P2P device as a group owner autonomously, entering a group owner receive mode in which a probe request can be received, and discovering an external device which transmits the probe request.

Device discovery method and apparatus of Wi-Fi P2P device

A Wireless-Fidelity (Wi-Fi) service method and system are provided. A beacon message and probe response message may contain a service information field storing device information. Wi-Fi devices can exchange information on supported functions with each other and one Wi-Fi device may identify functions supported by another Wi-Fi device. Hence, a Wi-Fi connection can be set up through automatic provisioning. The method includes receiving, by a first Wi-Fi device in non-Access Point (AP) mode, messages from nearby Wi-Fi devices operating in AP mode, analyzing a service information field of each received message, determining a second Wi-Fi device that is manufactured by the same manufacturer as the first Wi-Fi device and is capable of supporting a requested service, establishing a connection with the second Wi-Fi device through Wi-Fi Protected Setup (WPS) based on automatic provision, and sending data associated with the requested service to the second Wi-Fi device for a Wi-Fi service.

Wi-Fi service method and system for Wi-Fi devices

A method and a system for providing a Wireless Fidelity (Wi-Fi) service, in which when multiple counterpart devices are selected based on manufacturer information and support information on supported functions and capability defined in a service information field of each beacon message or each probe response message, a final device is determined by checking multiple pieces of signal information of the selected counterpart devices, are provided. The method includes receiving messages from multiple counterpart devices, selecting one or more counterpart devices, each of which supports a requested service, from an identical manufacturer when the messages are received, checking multiple pieces of signal information of the selected counterpart devices when the number of the selected counterpart devices is greater than one, and determining a device having the signal information satisfying set conditions as a final device.

Method and system for providing Wi-Fi service by Wi-Fi device

A system of Wi-Fi terminals and a channel operation method for the same are provided. The method includes selecting a user function of a sending terminal including a Wi-Fi module, determining whether the selected user function is a Wi-Fi related function, performing, when the selected user function is the Wi-Fi related function, by the sending terminal, a search for a terminal capable of handling the user function, selecting, by the sending terminal, a found terminal as a receiving terminal, automatically establishing, by the sending terminal, a Wi-Fi channel to the receiving terminal by automatically sending a Probe Request message containing a Personal Identification Number (PIN) code, sending, by the sending terminal, data generated by the user function to the receiving terminal through the Wi-Fi channel, and outputting, by the receiving terminal, the received data.
