    (c) at least one hub switching means, each hub switching means being coupled to at least one lata switching means with each hub switching means having jurisdiction over at least one lata switching means;

    (d) each of the local switching means having means for receiving requests for pages called to the local switching means including a number identifying the subscriber of the local paging service to whom the page should be charged and an identification of the paging receiver to receive the page, processing means for determining any area destinations to which a page should be transmitted in the network by matching the identification number of each request for a page with an identical number stored in the subscriber file and identifying any area destinations stored in the subscriber file, adding any identified area destination to the request to form at least one page with an area destination in the network, for each request for a page which is destined for the local paging service of the local switching means causing a page to be formed and the page to be transmitted to the local paging service for broadcast, and for pages having an area destination other than the local paging service of the local switching means causing the page to be transmitted to the lata switching means having jurisdiction over the local switching means, and means for receiving pages from the lata switching means having jurisdiction over the local switching means and transmitting the pages received from the lata switching means to the local paging service coupled to local switching means for broadcast, and all area destinations of pages in the network being determined exclusively by the subscriber files of the local switching means; and

    (e) each of the lata switching means having an input means for receiving pages from the at least one local switching means over which the lata switching means has jurisdiction, an input means for receiving pages from a hub switching means having jurisdiction over the lata switching means, processing means for processing an area destination contained in received pages, output means for outputting pages for transmission to each of local switching means over which the lata switching means has jurisdiction, output means for outputting pages for transmission to the hub switching means which has jurisdiction over the lata switching means, and wherein the processing means outputs the processed pages to the output means for outputting pages for transmission to each of the local switching means which have an area destination of the lata switching means and outputs the pages to the output means for transmitting pages to the hub switching means having jurisdiction over the lata switching means which do not have an area destination of the lata switching means.
