    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 frequency agile data receiver checks are needed, according to a first protocol, among a plurality of channels to find a channel carrying data. A control activated by the user interrupts this first protocol and institutes a second protocol different than the first. Applied to a paging receiver, the first protocol may sequentially tune the receiver to a plurality of previously identified channels to locate a channel on which paging data is satisfactorily received. The second protocol may sequentially tune to all possible channels to locate such a channel. By this arrangement, a person who knowingly moves to a new locality (e.g., flies to another city) can instruct the paging receiver to abandon a previously identified list of candidate channels and to begin a spectrum-wide scan to locate a new satisfactory paging channels.

    摘要: A paging system repeatedly broadcast each message and associates a sequential message number with each paging message. The message number in each message serves two functions. First, the message number is used to determine if the same message was previously received and second, when a subscriber reviews the messages, missing messages can be readily detected by skipped message numbers. All messages that are transmitted are also stored at a clearinghouse and a subscriber can telephone the clearinghouse facility and request that particular missed messages be retransmitted or given by voice response over the telephone.

    摘要: The present invention provides a highly reliable radio paging system. The radio paging system of the present invention provides a combination of time, frequency and spacial diversity in order to increase the reliability of the system. Time diversity is provided by broadcasting the same message at a number of different times. Spacial diversity is achieved by broadcasting the same message from a number of different locations. Frequency diversity is achieved by broadcasting the same message at a number of different frequencies. The paging receiver according to the present invention is designed to receive messages on a number of different frequencies; however, the pager only responds to a message the first time that it receives the particular message. The combination of time, frequency, and spacial diversity provided by the present invention results in a highly reliable radio paging system.
