Abstract: A method for monitoring paging messages in a mobile station with a subscriber identity card camping on a cell is provided. A paging message from the cell is monitored at a set of M predetermined time intervals. A first paging message with a first subscriber identity information being successively broadcasted in the paging channel at a Nth predetermined time interval and a (N+i)th predetermined time interval of the set of M predetermined time intervals is determined. A second paging message with a second subscriber identity information being successively broadcasted in the paging channel at the Nth predetermined time interval and a (N+j)th predetermined time interval of the set of M predetermined time intervals is determined, wherein j>i. The paging channel is monitored at a (N+i)th predetermined time interval and a (N+j)th predetermined time interval of following predetermined time intervals subsequent to the M predetermined time intervals.

Abstract: A paging channel is monitored at a special position of every predetermined time interval subsequent to the last monitored time. It is detected whether a same first identity information is repeatedly broadcasted in the paging channel at special positions of different predetermined time interval. A total number of periodically repeated messages containing the same first identity information is determined. A new time interval is determined by multiplying a time period between two successive repeated paging messages with the total number of periodically repeated paging messages, wherein the new time interval has a monitoring interval (having a plurality of predetermined time intervals) equaling to the length of the time period and a sleep interval. The paging channel is monitored at special positions of the plurality of predetermined time intervals in every new time interval subsequent to the last monitored time so as to receive subsequent paging messages from the cell.
