Disclosed herein is a mobile handset, part of an open update framework, that uses a mime-type to determine if an update package received is appropriate for an update activity, or is currently supported. In addition, it uses the mime-type to determine where the downloaded update package needs to be stored in non-volatile memory, such as Flash. It also uses the mime-type to invoke an appropriate firmware, software or configuration update agent.

Open update framework for mobile handsets capable of processing packages based on mime-types

An update system comprising a mobile handset with an update agent and an operating system, such as Symbian OS, that supports a file system, and a server, facilitates the download of update packages from the server and the subsequent update of firmware/software in the mobile handset. In an embodiment of the present invention, the update agent may be incorporated into the phases of the bootstrap process that an operating system, such as Symbian OS, may execute during startup.

Disclosed herein is an electronic device network having a plurality of associated electronic devices. The electronic devices may include an update agent adapted to decipher code and/or data segments. The update agent may also be adapted to modify and/or upgrade firmware and/or software components resident in the electronic devices by employing the deciphered code and/or data segments along with contents of an update. An update generator, resident in the electronic devices may employ deciphering techniques to the code and/or date segments to extract enciphered code and/or data segments. The update generator may also process the code and/or data segments to generate an update including difference information. The update generator may also be adapted to encipher difference information in the generated update.

Electronic device network supporting enciphering and deciphering and update generation in electronic devices

An object ordering tool analyzes output from a linker to determine ordering of code objects in first and second firmware binary images. The tool produces a linker script file used by the linker to link the code objects of the second firmware binary image in a more optimal order for production of updating information used in the electronic device for updating firmware of the electronic device.

A build optimization tool analyzes builds of software/firmware to determine the ordering of code objects in first and second code versions for an electronic client device such as a cellular phone, personal digital assistant, or pager. The build optimization tool produces information for use by a software linker to link the code objects of the second code version in a more optimal order for the production of updating information used in the electronic client device for updating the software/firmware of the electronic client device.

Build optimizer tool for efficient management of software builds for mobile devices

Disclosed herein is an electronic device network including a plurality of electronic devices. The electronic devices may each have software adapted to update firmware/software resident in the electronic device in compressed form. The software adapted to update firmware/software may also be adapted to employ the decompressed firmware/software components in conjunction with additional update information in performing an update on the electronic devices. An update generator in the electronic device network may be adapted to employ compression and decompression techniques upon generated updates for use in updating the electronic devices. The update generator may also be adapted to generate update packages using the decompressed update information. The update generator may also be adapted to selectively compress the generated update packages usable for updating the electronic devices prior to the update package being transmitted to eth electronic device.
