    摘要: A wide area paging system is disclosed in which paging messages input to the system in one local area can be broadcast to a receiver in any other local area without necessarily broadcasting the message in all areas. A local area clearinghouse in each area stores resident subscriber data including current location and receiver serial number. This data is used to transfer messages over a data network to the correct clearinghouse. The system uses a TDM data protocol. The data is encoded and transmitted at a very high rate (e.g., 19,000 baud) in short packets (256 bits/13 milliseconds) via stereo FM sidebands. Receivers are assigned to receive sequentially numbered time slots matching a portion of their address. The addresses of intended receivers are included in the data packets. Battery-powered receivers are deactivated between packets and reactivated in accordance with the sequential time slot number scheme to receive an incoming packet. Messages longer than a packet are segmented and transmitted in two or more packets, linked together by data contained in the packets. A watch pager used in the system employs a wristband antenna which electromagnetically couples to the user's body. The watch pager displays time, telephone numbers and icons representing common types of paging messages.

    摘要: A local telephone/radio paging system includes a local paging system, a telephone, and a memory for indicating which telephone numbers are within the local area. When a telephone number is dialed, if the person dialed does not answer, the telephone switching equipment checks the memory to determine whether the dialed number is within the local paging area. If so, a local paging transmitter is activated, paging the person assigned to the unanswered phone. Such a paging transmitter may be included in each phone, or a single central local transmitter may be employed. The paging receivers desirably include alphanumeric displays and indicate the number of the telephone that originated the unanswered call, so that the person carrying the paging receiver may call back immediately.
