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&#x3e;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.

Methods for monitoring paging messages with reduced power consumption and communications apparatuses utilizing the same

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.

A method for monitoring paging messages in a mobile station with a subscriber identity card camping on a cell is provided. A paging channel is monitored at every end of predetermined time interval subsequent to the last monitored time. It is detected whether the same identity information is repeatedly broadcasted in the paging channel at different ends of predetermined time interval. A new time interval is determined when detecting that the same identity information is repeatedly broadcasted. The paging channel is monitored at every end of new time interval subsequent to the last monitored time so as to receive subsequent paging messages from the cell, wherein the new time interval is longer than the predetermined time interval.

A specific code indicative of a specific request is used to provide a communication device with an ability to send specific calls, such as emergency calls and silent calls, and the ability to distinguish the specific calls from the received calls. A method of sending a call includes generating a specific code indicative of a specific request, adding the specific code to a call, and then sending the call to a receiver for notifying the receiver of the specific request. A method of receiving a call includes determining whether a received call comprises a specific code indicative of a specific request, and generating an indication in response to the specific request when the received call is determined to comprise the specific code.

Method of sending and receiving call with specific request

An embedded memory device solves the problem of the low reliability of the circuit due to the unstable power source. The embedded memory includes a metal-oxide semiconductor (MOS) capacitor and a metal-insulator-metal (MIM) capacitor to increase the stability of the power source ring to stabilize the voltage of the embedded memory and stabilize the voltage for the peripheral circuit of the embedded memory.
