Method for using legacy Wi-Fi and Wi-Fi P2P simultaneously

1. A method for connecting to a Wi-Fi network in an electronic device, the method comprising:

entering a device discovery process of Wi-Fi Peer-to-Peer (P2P), if a Wi-Fi P2P connection is requested while connecting a legacy Wi-Fi;

acquiring a Group Owner (GO) right of Wi-Fi P2P in the device discovery process;

performing a listen state over the same channel as a channel where the legacy Wi-Fi is in use, through the acquisition of the GO right, and performing a search state over a social channel of Wi-Fi P2P; and

repeating the listen state and the search state until the device discovery process is ended.

2. The method of claim 1 , wherein the acquiring comprises enabling an autonomous GO mode in the same channel as the channel where the legacy Wi-Fi is in use.

3. The method of claim 2 , further comprising disabling the autonomous GO mode if the device discovery process is ended.

4. The method of claim 1 , wherein the social channel includes a channel #1, a channel #6 and a channel #11.

5. The method of claim 1 , wherein the entering of the device discovery process of Wi-Fi P2P occurs based on at least one of a menu selection and execution of a predetermined application.

6. The method of claim 1 , wherein the entering of the device discovery process comprises performing a channel scanning process.

7. The method of claim 1 , further comprising connecting to the Wi-Fi P2P based on a result of the listen state and the search state.

8. A method for connecting to a Wi-Fi network in an electronic device, the method comprising:

acquiring a Group Owner (GO) right of Wi-Fi Peer-to-Peer (P2P), if an entry into a listen mode of Wi-Fi P2P is requested during execution of a legacy Wi-Fi; and

entering the listen mode over the same channel as a channel where the legacy Wi-Fi is in use, through the acquisition of the GO right.

9. The method of claim 8 , wherein the GO right of Wi-Fi P2P is acquired as an autonomous GO mode is enabled in the same channel as the channel where the legacy Wi-Fi is in use.

10. The method of claim 8 , wherein the listen mode enters a sleep mode using an opportunistic power save method.

11. The method of claim 10 , wherein the sleep mode is released in a period which is set as a Client Traffic Window (CTWindow) in a period set for the sleep mode.

12. The method of claim 11 , wherein a period of the CTWindow corresponds to a period which is about a half of a Target Beacon Transmission Time (TBTT) period.

13. An apparatus for connecting to a Wi-Fi network 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 device discovery process of Wi-Fi Peer-to-Peer (P2P), if a Wi-Fi P2P connection is requested while connecting a legacy Wi-Fi,

acquire a Group Owner (GO) right of Wi-Fi P2P in the device discovery process,

perform a listen state over the same channel as a channel where the legacy Wi-Fi is in use, through the acquisition of the GO right, and perform a search state over a social channel of Wi-Fi P2P, and

repeat the listen state and the search state until the device discovery process is ended.

14. The apparatus of claim 13 , wherein the controller is further configured to enable an autonomous GO mode in the same channel as the channel where the legacy Wi-Fi is in use.

15. The apparatus of claim 14 , wherein the controller is further configured to disable the autonomous GO mode if the device discovery process is ended.

16. The apparatus of claim 13 , wherein the controller is further configured to connect to the Wi-Fi P2P based on a result of the listen state and the search state.

17. An apparatus for connecting to a Wi-Fi network in an electronic device, the apparatus comprising:

a communication module; and

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

acquire a Group Owner (GO) right of Wi-Fi Peer-to-Peer (P2P), if an entry into a listen mode of Wi-Fi P2P is requested during execution of a legacy Wi-Fi, and

enter the listen mode over the same channel as a channel where the legacy Wi-Fi is in use, through the acquisition of the GO right.

18. The apparatus of claim 17 , wherein the GO right of Wi-Fi P2P is acquired as an autonomous GO mode is enabled in the same channel as the channel where the legacy Wi-Fi is in use.

19. 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 a method for connecting to a Wi-Fi network in an electronic device, the method comprising:

entering a device discovery process of Wi-Fi Peer-to-Peer (P2P), if a Wi-Fi P2P connection is requested while connecting a legacy Wi-Fi;

acquiring a Group Owner (GO) right of Wi-Fi P2P in the device discovery process;

performing a listen state over the same channel as a channel where the legacy Wi-Fi is in use, through the acquisition of the GO right, and performing a search state over a social channel of Wi-Fi P2P; and

repeating the listen state and the search state until the device discovery process is ended.

20. 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 a method for connecting to a Wi-Fi network in an electronic device, the method comprising:

acquiring a Group Owner (GO) right of Wi-Fi Peer-to-Peer (P2P), if an entry into a listen mode of Wi-Fi P2P is requested during execution of a legacy Wi-Fi; and

entering the listen mode over the same channel as a channel where the legacy Wi-Fi is in use, through the acquisition of the GO right.
