Abstract

A software upgrade server that remotely links a software upgrade file as a DLL and transmits the DLL to a mobile station via a wireless network. The mobile station comprises a memory for storing the software file and a controller that communicates with the software upgrade server. The controller receives a message from the software upgrade server indicating a software file is available for upgrading. The controller determines an available space in the memory where the available software file may be installed and transmits to the software upgrade server a target address at the start of the available memory space. The server uses the target address to link a plurality of object files into a DLL and transmits the DLL to the mobile station.

Claims

1. A software upgrade server capable of transmitting a software file to a wireless mobile station via a wireless network, said software upgrade server comprising:

a database capable of storing a plurality of software upgrade files as a plurality of object files; and

an upgrade controller associated with said database capable of communicating with said mobile station via said wireless network, wherein said upgrade controller receives from said mobile station a select message selecting one of said plurality of software upgrade files and a target address associated with an available space in a memory of said mobile station, and wherein said upgrade controller, in response to receipt of said target address, links selected ones of said plurality of object files to form a dynamically linked library (DLL) file based on said target address and transmits said DLL file to said mobile station.

2. The software upgrade server as set forth in claim 1 wherein said target address indicates a starting point of said available space in said mobile station memory.

3. The software upgrade server as set forth in claim 2 wherein said available space is a contiguous block of memory capable of storing all of said DLL file.

4. The software upgrade server as set forth in claim 1 wherein said upgrade controller is capable of receiving an upgrade request message from said mobile station requesting a list of ones of said plurality of software upgrade files capable of being executed by said mobile station.

5. For use in a software upgrade server capable of wirelessly transmitting a software file to a mobile station via a wireless network, a method of upgrading software files in the mobile station comprising the steps of:

storing a plurality of software upgrade files as a plurality of object files in a database;

receiving from the mobile station a select message selecting one of the plurality of software upgrade files and a target address associated with an available space in a memory of the mobile station;

in response to receipt of the target address, linking selected ones of the plurality of object files to form a dynamically linked library (DLL) file based on the target address; and

transmitting the DLL file to the mobile station.

6. The method as set forth in claim 5 wherein the target address indicates a starting point of the available space in the mobile station memory.

7. The method as set forth in claim 6 wherein the available space is a contiguous block of memory capable of storing all of the DLL file.

8. The method as set forth in claim 7 further comprising the step of receiving an upgrade request message from the mobile station requesting a list of ones of the plurality of software upgrade files capable of being executed by the mobile station.
