METHOD AND SYSTEM FOR ESTABLISHING WIRELESS LOCAL AREA NETWORK LINK BETWEEN PORTABLE TERMINALS
First Claim
1. A method of establishing a wireless local area network (WLAN) link in a portable terminal, the method comprising:
- transmitting a connection request message including a first partial security key being a portion of a first security key to a second portable terminal through a cellular network, by a first portable terminal;
outputting a sound including a second partial security key being a remaining portion of the first security key, after transmitting the connection request message;
receiving a request of a WLAN connection including a second security key from the second portable terminal having received the sound through a WLAN; and
establishing the WLAN link with the second portable terminal when the second security key corresponds to the first security key.

9. A method of establishing a wireless local area network (WLAN) link in a portable terminal, the method comprising:
-
receiving a connection request message from a contact server through a cellular network via a push operation, by a second portable terminal; turning-on a microphone for receiving a sound output from a first portable terminal, in response to the connection request message; receiving the sound output from the first portable terminal through the microphone; acquiring a first partial security key according to the connection request message and a second partial security key according to the sound; combining the second partial security key with the first partial security key to acquire a security key; and requesting a WLAN connection to the first portable terminal using the acquired security key. - View Dependent Claims (10, 11, 12, 13)

14. A first portable terminal comprising:
-
a memory which stores a program; and a controller which executes the program to establish a wireless local area network (WLAN) link with a second portable terminal, wherein the program comprises commands which, when executed by the controller, cause the controller to execute a method comprising; transmitting a connection request message including a first partial security key being a portion of a first security key to the second portable terminal through a cellular network; outputting a sound including a second partial security key being a remaining portion of the first security key, after transmitting the connection request message; receiving a request of a WLAN connection including a second security key from the second portable terminal having received the sound through a WLAN; and establishing the WLAN link with the second portable terminal when the second security key corresponds to the first security key. - View Dependent Claims (15, 16)
