PURPOSE: The method is provided to transceive data between the mobile terminal and an AC(Access Point), so that the mobile terminal can notify an emergent state of a patient to a home location AC and the home location AC can notify necessary information to the patient. CONSTITUTION: An association is requested to a home location AP(Access Point)(202). The confirmation of the association is delivered(203). The mobile terminal periodically confirms whether a beacon signal of the AP is received(204). If a beacon signal is received, whether a basic service network identifier is identical is confirmed(205). If so, a synchronization clock is regulated(206). If the basic service network identifier is not identical, a re-association is requested to the AP(209). Whether the re-association is responded is checked five times(210). If responded, a synchronization clock is regulated(206), and if not responded, the non-response is notified to a network for maintenance(211). If a beacon signal is not received, a wireless channel and clock are regulated(207), and whether beacon information of a base station is received is repeatedly checked five times at maximum(208).
