intelligent paging services provided by a gsm - based mobile communication network are employed in a mobile - based client - server system to provide automatic notification of a mobile client station of the type and quantity of information awaiting delivery to a mobile client station at a centralized server , so that the client station may then establish a communication link to receive the information , without otherwise requiring a costly polling scheme . in a preferred embodiment , the server evaluates received or otherwise generated information that is intended for a respective client station to determine whether the information is of a selected type and / or quantity requiring notification of the client station . if so , the server transmits a message from a transceiver associated with the server to a transceiver associated with the client station , the message indicating the type and quantity of information awaiting delivery to the client station . the respective client station evaluates the received message and , if the specified information type and quantity justify the time and expense , establishes a log - on connection with the server via the respective client station and server transceivers in order to receive the information and , if expedient , conduct further information exchanges .
