<p>In a wide-area paging system, each of paging terminals (2-1 , ...2-N) connected to a switched communication network (1) covers a home service area and includes a processor (21) for conversion of an incoming calling signal received from the network to a paging signal unique to the home service area and transmits the paging signal to radio transmitters (3-1) located in the home service area. One of the paging terminals (2-1) includes a memory (24) for storing telephone numbers of pagers registered to wide-area paging service, and determines whether a destination pager paged by the transmitted paging signal is registered to the wide-area paging service, and reads a telephone number from the memory in accordance with the incoming calling signal from the network if the pager is entitled to the wide-area paging service. An outgoing calling signal is derived from the read telephone number and transmitted to another paging terminal either by way of an interface (25) and the network (1), or directly (26; Fig.3). To fit the system to an existing paging terminal (2A-1; Fig.2) an interface (26) can receive the output of the terminal, and a second processor (27) to which the wide-area memory (28) is attached derives the outgoing calling signals. <IMAGE></p> |
