Title:
METHOD AND APPARATUS FOR CONFIGURING A MODEM
Document Type and Number:
WIPO Patent Application WO1998017075
Kind Code:
A3
Abstract:
An apparatus and method for configuring a modem in a cellular radio communications system when the modem front end is physically separated from the modem back end. The method includes the steps of inputting the configuration information, comparing that configuration information against default configuration parameters to identify any non-default configuration information, storing that non-default configuration information, and transmitting that non-default configuration information via a radio link to the modem back end on each call-attempt. In this manner, the problem of lost configuration information is overcome, and the modem back end is properly configured for operation with communication software programs on each data call-attempt. The apparatus allows for configuration information to be retained by the modem front end for an entire communication session and the transmission of non-default configuration information to the paired modem back end each time a call-attempt is made. Use of the method and apparatus results in an improved performance to users of modems in a cellular radio communications system, particularly whenever a data call-attempt fails on the first try.
