Abstract: In a paging system, a central paging station determines a preferred amount of time, or "sleep value," that a paging device is to be inactive during a paging cycle based upon the volume of page messages that paging device historically receives during given time periods. After determining a preferred sleep value, the central paging station creates and transmits a wake-up interval page message. The paging device receives the wake-up interval page message and changes its wake-up interval to correspond to the one contained in the received page message.

Abstract: An electronic messaging network comprises a network operation center and plural message terminals, all including memories for storing corresponding files of canned messages and associated message codes. To send a canned message, a calling party selects a canned message stored at one message terminal and transmits the assigned message code to a receiving party at another message terminal via the network operation center. The receiving terminal retrieves the selected canned message from its memory using the received message code for display to the receiving party. Files of canned responses and associated response codes may also be stored in the memories at the terminals and network operation center to allow the exchange of selected canned response options in conjunction with canned messages to be in response code form.
