Database system, data management system and communication terminal (DATABASE SYSTEM, DATA MANAGEMENT SYSTEM AND COMMUNICATION TERMINAL)

摘要

In addition to the central paging controller, the database includes a service center and is connected to the public switched network to provide voice information. A single pager / plurality of pagers to be paged from the central paging controller has a data transmission function. In connection with the voice information, the service center stores the ID information including the code data. The stored ID information is transmitted to the phaser (s) through the central paging controller and the transmitting base station. Using the transmission function, the pager (s) transmits the received ID information to the service center via the public line network. Therefore, the voice information stored in the service center can be output through the public network.
