Data messaging in a cellular communications network
First Claim
1. A system for communicating location or status information of a mobile item to be monitored using a cellular telephone network, comprising:
- a messaging unit coupled to the mobile item, the messaging unit having a cellular transceiver coupled to the cellular telephone network, the messaging unit operable to alter an identifier of the cellular transceiver to reflect the location or status information of the mobile item and to transmit the altered identifier of the cellular transceiver; and
a platform coupled to the cellular telephone network and operable to recognize a received altered identifier transmitted by the messaging unit to obtain the location or status information of the mobile item.

Abstract
A messaging unit (16) equipped with a cellular transceiver (38) is attached to a truck trailer (12) located within a communications network (10). The messaging unit (16) generates a data message in response to the occurrence of a reporting event. Upon generation of a data message, the cellular transceiver (38) transmits the data message over the network (10) via voice or data channels. The data message 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 message stored at the platform (24) or the clearinghouse (22) is accessed by a host (26). A data message may be sent over a voice channel of the network (10) subject to a handshake protocol between the messaging unit (16) and the platform (24). Data messages may also be sent over a data channel of the network (10) by altering the mobile identification number (MIN) or electronic serial number (ESN) of the cellular transceiver (38). Furthermore, data messages may be sent over a data channel of the network (10) by issuing a feature request with appended data digits.
