Abstract
A messaging unit equipped with a cellular transceiver is attached to a truck trailer or a monitoring station located within a communications network. The messaging unit generates a data message in response to the occurrence of a reporting event. Upon generation of a data message, the messaging unit transmits the data message over the network via voice or data channels. Data messages may be sent over a data channel of the network using a feature request.
