  • User interface with improved data entry features for telephone system
    Patent number: 6405060
    Abstract: An improved user interface for a cellular telephone system subscriber unit, including the following functions: (1) a predictive keyboard input method for speeding up input on a telephone with a space limited keyboard; (2) a word completion method for speeding up input; (3) a distinctive signaling method useful in a dual-mode or tri-mode cellular phone system that incorporates both voice call functionality and data messaging functionality; (4) a secret message method that permits secret messages to be received by an authorized user of a cellular telephone that includes a data messaging capability; (5) a message screening method that permits a user to set a message screening mode in a cellular telephone; (6) an improved “scratchpad” method which permits a user to enter a telephone number into a storage register of a cellular telephone while in the middle of a voice call, visually verify the entry, and then save the number to a rapid redial location for later use; (7) a global search method for searc

  • Cellular data overlay system providing packet-switched communication data service over a selected channel which is not in use by a circuit-switched communication subsystem
    Patent number: 5528664
    Abstract: A cellular telephone system includes a packet-switched digital data communication subsystem overlaying a circuit-switched (e.g., voice) communication subsystem, with voice and data services sharing the same voice channels. The voice communication subsystem provides voice services independently of the operation of the data communication subsystem. On the other hand, the data communication subsystem monitors use of the voice channels for voice communication, and, in response thereto, temporarily allocates one or more of the available voice channels for data service. In a preferred embodiment, each data basestation transmits, from time to time, an available-channel signature to identify those, if any, of the data-allocated channels that are not then being used to transmit voice or data.
