Disclosed is a method for controlling a paging alert level of a mobile
station in a mobile communication system. A base station sets information of a
type and a level of a paging alert tone of the mobile station in a broadcasting
channel (BCH) message and transmits the BCH message to every mobile station within
a cell of the base station. The mobile station then generates a paging alert tone
according to the information of the type and the level of the paging alert tone,
included in the received BCH message.
