Abstract

A method and an apparatus for Wi-Fi connection based on Wi-Fi Protected Setup (WPS) in a portable terminal are provided. The method includes entering a group owner mode of Wi-Fi Direct when enabling of WPS is requested, after entering the group owner mode, entering a WPS session mode where the portable terminal is operable in a WPS registrar mode, determining whether an Access Point (AP) whose WPS session of the WPS registrar mode is enabled or a device whose group owner mode is enabled, exists nearby, and when an AP whose WPS registrar mode is enabled is discovered, disabling the WPS registrar mode and the group owner mode, enabling a WPS session where the portable terminal is to operate in a WPS enrollee mode, and accessing the discovered AP.

Claims

1. A method for connecting to a Wireless-Fidelity (Wi-Fi) in an electronic device, the method comprising:

entering a group owner mode of a Wi-Fi Peer-to-Peer (P2P) if a Wi-Fi connection is requested;

discovering an external device whose group owner mode is enabled;

determining the group owner of Wi-Fi P2P from among the electronic device and the discovered external device; and

connecting to a Wi-Fi P2P group based on a result of the determining of the Wi-Fi P2P group owner.

2. The method of claim 1, wherein the connecting to the Wi-Fi P2P group comprises:

comparing, if the external device whose group owner mode is enabled is discovered, a prefix of a Service Set Identifier (SSID) name of the electronic device, which is generated in a group owner mode entry process, with a prefix of an SSID name of the discovered external device; and

connecting to the Wi-Fi P2P group based on a result of the comparing of the prefix of the SSID.

3. The method of claim 2, wherein the connecting to the Wi-Fi P2P group comprises acquiring group owner rights by the device corresponding to a prefix having a greater value among the prefix of the SSID name of the electronic device and the prefix of the SSID name of the discovered external device, and connecting to the Wi-Fi P2P group.

4. The method of claim 2, wherein the connecting to the Wi-Fi P2P group comprises acquiring group owner rights by the device corresponding to a prefix having a lesser value among the prefix of the SSID name of the electronic device and the prefix of the SSID name of the discovered external device, and connecting to the Wi-Fi P2P group.

5. The method of claim 2,

wherein the connecting to the Wi-Fi P2P group comprises exchanging Probe Request and Probe Response messages of an Institute of Electrical and Electronics Engineers (IEEE) 802.11 Medium Access Control (MAC) protocol, and

wherein the Probe Request comprises at least one of a P2P Information Element (IE), a Wi-Fi Simple Configuration (WSC) IE, and a Supplemental Registration (Supp Reg) IE, and wherein the Probe Response comprises at least one of a P2P IE, a WSC IE, a Robust Security Network (RSN) IE, and a Supp Reg IE.

11. At least one non-transitory computer readable storage medium for storing a computer program of instructions configured to be readable by at least one processor for instructing the at least one processor to execute a computer process for performing the method of claim 1.

6. An apparatus for connecting to a Wireless-Fidelity (Wi-Fi) in an electronic device, the apparatus comprising:

a communication module; and

a controller operatively coupled with the communication module, the controller configured to;

enter a group owner mode of Wi-Fi Peer-to-Peer (P2P) if a Wi-Fi connection is requested,

discover an external device whose group owner mode is enabled,

determine the group owner of Wi-Fi P2P from among the electronic device and the discovered external device, and

connect to a Wi-Fi P2P group based on a result of the determining of the Wi-Fi P2P group owner.

7. The apparatus of claim 6, wherein, if the external device whose group owner mode is enabled is discovered, the controller is further configured to:

compare a prefix of a Service Set Identifier (SSID) name of the electronic device, which is generated in a group owner mode entry process, with a prefix of an SSID name of the discovered external device, and

connect to the Wi-Fi P2P group based on a result of the comparing of the prefix of the SSID.

8. The apparatus of claim 7, wherein a device, corresponding to a prefix having a greater value among the prefix of the SSID name of the electronic device and the prefix of the SSID name of the discovered external device, acquires group owner rights and connects to the Wi-Fi P2P group.

9. The apparatus of claim 7, wherein a device, corresponding to a prefix having a lesser value among the prefix of the SSID name of the electronic device and the prefix of the SSID name of the discovered external device, acquires group owner rights and connects to the Wi-Fi P2P group.

10. The apparatus of claim 7,

wherein, if the external device whose group owner mode is enabled is discovered, the controller is further configured to connect to the Wi-Fi P2P group by exchanging Probe Request and Probe Response messages of an Institute of Electrical and Electronics Engineers (IEEE) 802.11 Medium Access Control (MAC) protocol, and

wherein the Probe Request comprises at least one of a P2P Information Element (IE), a Wi-Fi Simple Configuration (WSC) IE, and a Supplemental Registration (Supp Reg) IE, and wherein the Probe Response comprises at least one of a P2P IE, a WSC IE, a Robust Security Network (RSN) IE, and a Supp Reg IE.
