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,wherein the second partial security key is loaded into the sound.

20. A non-transitory computer-readable recording medium storing a program that, when executed by a computer, causes the computer to execute a method comprising:
-
transmitting a first partial security key and a second partial security key, which have been divided from a first security key, through a cellular network and by a sound, respectively; combining the first and second partial security keys, which have been received through the cellular network and by the sound, with each other to generate a second security key; and establishing a wireless local area network link using the first security key and the second security key, wherein the transmitting comprises outputting the first partial security key and the second partial security key, and the security key is loaded into the sound.
