    Abstract: A two-way communication network for routing communications from and to a plurality of subscriber units at various geographic locations. The network includes a plurality of low power local subscriber units adapted to transmit and receive digital data messages of variable lengths and a central transmitter station (CTS). The CTS includes data transmission and data reception facilities. The transmission facilities transmit messages to the local subscriber units and include a synchronization unit that synchronizes the transmission facilities with a precision clock signal. The data reception facilities receive and process messages from the subscriber units. Remote receiver units are dispersed over the geographic area served by the CTS and relay digital messages transmitted from the subscriber units to the CTS. Each subscriber unit communicates with the CTS by way of digital data signals synchronously related to said precision clock signal and timed for multiplexed message transmission.

    Abstract: An integrated communications terminal including a selectable channel demodulator and decoder, a time-division-multiplexed (TDM) channel demodulator and decoder, a data processor and controller, an audio decompressor, a D/A converter, and a data coder and modulator. The terminal is used with a mobile station having a message display, an input device, RF electronics, and an optional transmitter. The selectable channel demodulator outputs a selectable intermediate-frequency signal as in-phase and quadrature-phase signals for decoding by the selectable channel decoder. The TDM channel demodulator generates a frequency offset signal and outputs in-phase and quadrature-phase TDM signals for decoding by the TDM channel decoder as a TDM-data signal. The data processor and controller time-demultiplexes the TDM-data signal as a control signal, a TDM channel and selectable channel look-up table, and paging and message signals, and generates a transmitter frequency command signal, a selectable data rate and frequency command signal, and a TDM data rate and frequency command signal. The audio decompressor outputs a digital audio data signal. The D/A converter outputs analog audio signals. The carrier signal frequency of the transmitter is set by the transmitter frequency command signal generated by the data processor and controller. The data coder and modulator encodes a data signal and then modulates a carrier signal with the coded data signal to create a data-modulated signal. The transmitter amplifies and transmits the data-modulated signal.

    Abstract: A communication system capable of targeting a demographically or psychographically defined audience. A master database (20) is maintained, containing demographic and psychographic information about each audience member. This information is transmitted and stored in a channel selection/decoder (100) unit associated with each audience member's receiver. Multiple media messages are transmitted to each audience member. Accompanying the transmission is a selection profile command, which details the demographic/psychographic profile of audience members that are to receive each media message. The channel selector/decoder (100) unit associated with each member's receiver compares the selection profile with the demographic/psychographic information about the audience member and selects the appropriate media message for that audience member.

    Abstract: A method of transmitting addressed messages to subscribers comprises the steps of defining the group or individual subscriber to be addressed, creating the message, assigning the message to the individual or group to be addressed, scheduling the message for transmission, transmitting the message, and recording the transmission of the message. The message creating step further includes the steps of defining message attributes such as background color, creating sets of instructions for the subscriber, if required, setting a data field related to alerting the subscriber and compressing the data length of the message using a predetermined compression code. A system control computer, according to the present invention, comprises a billing computer interface for interfacing with a billing computer and a user interface for providing access to messaging services to a system operator, each of the billing and user interfaces for providing data to a group queuing subsystem and a system event scheduler, respectively. The user interface further accesses a database, the database shared by the system event scheduler and a message, device and group manager. The device manager in turn, when scheduled by the system event scheduler, coordinates the transmission of addressed messages via either a headend controller (via an inband channel) or an addressable data transmitter (via an out-of-band channel).
