Firmware upgrade system and method in a device management architecture
First Claim
1. A device firmware upgrade method, comprising:
- obtaining from a server, using a first protocol, identity information of an upgrade server adapted to operate with respect to a mobile communications device in a second protocol;
transmitting device image information relating to a device image associated with said mobile communications device to said upgrade server using said second protocol for computing a customized upgrade process with respect to said mobile communications device based on said device image information;
receiving a transaction from said upgrade server in said second protocol, said transaction including information defining said customized upgrade process computed at said upgrade server responsive to said device image information, and identity information of one or more content servers having upgrade resources;
issuing a download transaction to at least one of said one or more content servers based on said identity information received via said second protocol, said download transaction including said customized upgrade process computed at said upgrade server;
responsive to issuing said download transaction, receiving one or more upgrade files from said one or more content servers based on said customized upgrade process; and
upon completion of upgrading at least a portion of said mobile communications device'"'"'s device image based on said one or more upgrade files, providing a status indication to said server using said first protocol.

Abstract
In one embodiment, a device firmware upgrade scheme is disclosed for upgrading a device image of a mobile communications device. A device management session is established between the mobile communications device and a first server using a first protocol. Upon obtaining identity information of a second server operable to compute or otherwise determine a customized upgrade process, a device inventory is transmitted to the second server using a second protocol. Upon receiving the customized upgrade process, the mobile communications device downloads one or more upgrade files from one or more resources. Thereafter, the mobile communications device is operable to provide a status indication to the first server using the first protocol.

12. A mobile communications device, comprising:
-
a processor connected to a communication subsystem; a persistent memory storage having a device management (DM) module, said DM module operating under control of said processor and configured to engage in a device management session with a server using a first protocol and to obtain from said server identity information of an upgrade server adapted to operate with respect to said mobile communications device in a second protocol; and said processor and DM module further configured to; effectuate transmission of device image information relating to a device image associated with said mobile communications device to said upgrade server using said second protocol for computing a customized upgrade process with respect to said mobile communications device based on said device image information; process a transaction received from said upgrade server, said transaction including information defining said customized upgrade process computed at said upgrade server responsive to said device image information, and identity information of one or more content servers having upgrade resources; issue a download transaction to at least one of said one or more content servers based on said identity information received via said second protocol, said download transaction including said customized upgrade process computed at said upgrade server; responsive to issuing said download transaction, receive one or more upgrade files from one or more content servers based on said customized upgrade process; and provide a status indication to said server using said first protocol upon completion of upgrading at least a portion of said mobile communications device'"'"'s device image based on said one or more upgrade files. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
