  • Method and apparatus for providing a communication path using a paging network
    Patent number: 6308060
    Abstract: A system for providing a communication path includes a platform, a paging network, a mobile unit, and a mobile voice communications network. The platform delivers a paging signal comprising call setup information to a page receiver of the mobile unit using the paging network. A transceiver of the mobile unit selects a particular NAM in response to the call setup information and registers with the network using the selected NAM to enable the establishment of a communication path between the platform and the mobile unit.

  • Data messaging in a communications network using a feature request
    Patent number: 6240295
    Abstract: A messaging unit (16) equipped with a cellular transceiver (38) is attached to a mobile item (12) located within a communications network (10). The messaging unit (16) issues a feature request having data digits that represent information on the mobile item (12). The cellular transceiver (38) transmits the feature request using the network (10). The feature request is received at an MTSO (20) and then routed to a platform (24), a clearinghouse (22), or the platform (24) through the clearinghouse (22). The data digits are translated into information on the mobile item (12) and stored at the platform (24) or the clearinghouse (22) for access by a host (26).
