Abstract

An apparatus and method for performing an instant messenger function using a local area network (LAN) is provided whereby a first portable terminal and second portable terminals perform an instant messenger function via short-range communication. The first portable terminals and the second portable terminals respectively store user information and exchange the stored user information to establish themselves as messenger objects. The first portable terminal searches the second portable terminals of the messenger objects located within the short-range communication area obtains user information of the searched second portable terminals of messenger objects and updates the user information. The searched second portable terminals of the messenger objects are displayed as being active to allow a user to check the searched messenger objects and to perform an instant messenger function.
