First Claim
1. A method for a first portable terminal to communicate with a second portable terminal, the method comprising:
- displaying a contact list on a screen of the first portable terminal;
the first portable terminal receiving a user input indicating a selection of at least one contact from the contact list;
the first portable terminal transmitting, over a mobile communication network to the second portable terminal, connection information necessary for the second portable terminal to establish a wireless local area network (WLAN) link with the first portable terminal;
the first portable terminal receiving a WLAN connection request from the second portable terminal through a WLAN interface; and
the first portable terminal establishing the WLAN link to the second portable terminal in response to the connection request;
wherein a mode of the WLAN link is determined based on a type of an executed application.
