Abstract

Today, a GPRS device that can send and receive data cannot transmit emails and other data if it has only GSM level coverage. This means that currently, while the user is in GSM-only coverage, they may miss important emails, calendar requests, etc. that are normally contained in GPRS packets.

Today, a GPRS device that can send and receive data cannot transmit emails and other data if it has only GSM level coverage. This means that currently, while the user is in GSM-only coverage, they may miss important emails, calendar requests, etc. that are normally contained in GPRS packets.

Though no GPRS connection is available at this point, users are able to send and receive SMS messages. This means that data “could” be re-routed through  the GSM network, but the server has no idea if and when it should do this.

The system I propose will have the device inform the server what state it is in by sending a GPRS packet when it gets into GPRS coverage, or an SMS message to the server when it can only send SMS data. This can be extended to other network types as well and to hybrid devices that support many network types.

The key feature is that we can route data over other network types where the normal data packets would not normally or could not be sent.  And the user is totally unaware that the data was being sent over a different transport mechanism; the server would be connected to the cellular network to receive SMS messages. 

When a device activates on a server, it will tell the device its SMS number for communication when GPRS or its main network transport is not routeable.  Similarly, the device will register its SMS number to the server.
