Patent ID: 7127260

Claim:
A method for determining a paging alert mode of a mobile terminal in a mobile communication system, comprising the steps of: determining whether there exists a sub-BTS (Base Transceiver System), based on a broadcasting channel message provided from a main BTS; receiving a beacon paging group frame from the sub-BTS, when the sub-BTS exists; and upon receipt of the beacon paging group frame, changing the paging alert mode to a predetermined paging alert mode by determining that the mobile terminal is located in a sub-cell formed by the sub-BTS, and changing the paging alert mode to a silent paging alert mode, and upon failure to receive the beacon paging group frame, determining that the mobile terminal is not located in the sub-cell, and changing the paging alert mode to a paging alert mode set by a subscriber, wherein the sub-BTS controls a sub-cell, which is located within a main cell that is controlled by the main BTS.
