  • Wireless on-call communication system for management of on-call messaging and method therefor
    Patent number: 6720864
    Abstract: A wireless communication device (32) within a wireless on-call communication system (10) includes a device receiver (92) for receiving an on-call message (36), a device processor (98) coupled to the device receiver (92) for processing the on-call message (36); a device memory (100) coupled to the device processor (98) for storing the on-call message (36); and an on-call application (108) coupled to the device processor (98) having an on-call schedule (80) for defining an active time period (126) and an inactive time period (128). The device processor (98) processes the on-call message (36) during the active time period (126) and discards the on-call message (36) during the inactive time period (128).

  • Method and apparatus for pre-programmed call-back-number-determined alert
    Patent number: 5394140
    Abstract: A method and apparatus in a communication receiver (110) for controlling an alert in response to a received call-back number (233) include receiving (402) the call-back number (233). A processor (208) in the communication receiver (110) compares (406) the received call-back number (233) with a list of pre-programmed call-back numbers (226, 228, 230) stored in a memory (210). If the received call-back number (233) matches (408) one of the pre-programmed call-back numbers (226, 228, 230), the processor (208) selects (410) a pre-programmed alert (236, 238, 240) corresponding to the matched pre-programmed call-back number (233), and instructs (414) an alert generator (212) to generate the selected pre-programmed alert (236, 238, 240).
