Abstract
The present invention provides a system and method for instantly providing a packet-switched connection, e.g., GPRS, to a portable computer of an existing mobile station. According to exemplary embodiments of the present invention, a GPRS identifier is added to a modem's standard AT dial command in order to indicate that GPRS is requested. The modification to the modem's dial command is made in such a way so as to be compliant with the well known syntax rules set forth for that command. By modifying the modem's AT command set accordingly, an existing mobile station's portable computer will be capable of instantly supporting GPRS irrespective of the off-the-shelf operating system in use in the portable computer.
