In this way, although the terminal is not busy, the call connection cannot be established
[0009] Also, since fast-moving wireless LAN terminals have a strong battery drain, they can easily run out of power

Abstract

An apparatus for processing a call of a wireless LAN using a callback function and a method thereof are for connecting calls when target terminals (destination terminals) are converted into a keep-alive state from a keep-dead state (for example, out of an access point section or power is turned off) by periodically receiving state information of other terminals in a transmitting terminal. A structure is as follows: a terminal 1 or a terminal n periodically transmits a keep-alive signal to a wireless LAN exchange; the wireless LAN exchange considers a terminal from which the keep-alive signal is not transmitted as a keep-dead terminal, and transmits an the telephone number list of the keep-dead terminals to each terminal; after information between the terminals and the wireless LAN exchange is periodically transceived, when users substantially attempt calls to target terminals, a callback service is requested if telephone numbers of the target terminals are stored in the telephone number list, and the calls are automatically attempted to the target terminals from the terminal in case the target terminals are converted into a keep-alive state from a keep-dead state.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2002-76048 filed with the Korean Patent Office on Dec. 2, 2002, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Generally, the present invention relates to a device and method for handling calls of a wireless local area network (LAN) using a callback function, for handling calls between terminals operating on a wireless LAN, and more particularly, to a method for handling calls using a callback function. Device and method for calling function to handle wireless LAN calls, used for when a target terminal changes from a keep-alive state to a keep-dead state (such as leaving an access point (AP) part or shutting down power supply) to connect calls by periodically receiving the status information of other terminals at the sending terminal. Background technique [0003] Recently, as wireless office telephone services using wireless office solutions (WO...
