Eliminate mobile phone recalls, ensure reliability, and enhance customer satisfaction using Red Bend's vCurrent Mobile fi rmware over-the-air (FOTA) update solution. vCurrent Mobile dramatically shrinks update fi le size and overcomes barriers to reliable and cost-effective updating of firmware on mobile phones already in the hands of users.

vCurrent® Mobile Handset Update Suite

vCurrent Mobile enables mobile phone manufacturers and carriers to create compact firmware updates for mobile phone handsets and to install the updates over the air rapidly and with complete reliability.

Based on Red Bend's patented technology, vCurrent Mobile is comprised of two primary components: an update generator and an update installer.

vCurrent Mobile's Update Generator identifies the essential changes from an existing fi rmware version to a new, updated version and automatically creates an extremely compact package of these changes. The Update Generator also supports updating a handset's fi le system, which typically stores images, sounds, confi guration information, settings, design themes, icons, menus, system status and other information that affects device appearance, confi guration and branding.

vCurrent Mobile's Update Installer resides on the mobile handset itself and performs the update installation. Optimized for the limited memory available within the handset, the vCurrent Mobile Update Installer applies the updates in-place on the phone's firmware accurately and reliably. It performs this update on feature phones with monolithic firmware images and on smart-phones with compressed, multi-section images. The update installer also performs file system updates.

vCurrent Mobile Advantages

vCurrent Mobile supports advanced phone architectures. Using advanced algorithms, vCurrent Mobile supports Symbian OS and other architectures that employ compressed multi-section images, read-only fi le systems, a combination of NAND and NOR fl ash and other advanced features.

vCurrent Mobile speeds up flash reprogramming. By updating only the changed sectors of the fi rmware image, vCurrent Mobile signifi cantly reduces the time the handset is out of service for updating and minimizes the user's inconvenience. vCurrent Mobile's patented computational update technology can guarantee consistent update performance for an unlimited number of on-device updates, from any firmware version to any other version.

vCurrent Mobile optimizes on-device memory. Using a unique "in place update" algorithm, vCurrent Mobile requires only minimal working memory to perform updates while providing control over the amount of fl ash memory required. This patented technology resolves complex "write before read" issues so that firmware can be updated rapidly without adding costly memory.

vCurrent Mobile can be integrated into handset firmware in a matter of days. vCurrent Mobile's unique technology and QuickPort™ process allow handset manufacturers to integrate the fi rmware update technology without restructuring device fi rmware and with no impact on the fi rmware development tool chain. As a result, integration has been proven to be signifi cantly faster and less expensive than alternative solutions.

vCurrent Mobile ensures 100% fault-tolerant update integrity and completion. vCurrent Mobile eliminates the risk of disabling devices due to errors or unexpected disruptions in the update process. In the event of a power loss, it automatically resumes the update from the point of interruption.

vCurrent Mobile ensures security for all stages of the update process. Using a patented pre-installation verifi cation technique, vCurrent Mobile software verifi es that the newly created software version is 100% accurate, bug-free and will install properly, prior to the update process getting underway.

vCurrent Mobile operates with other mobile device management solutions. vCurrent Mobile works with all existing mobile device data distribution and transfer solutions and all standard protocols.

vCurrent Mobile Update Installer minimizes the on-device footprint. The Update Installer software requires only one fl ash sector of 64KB as permanent allocation for the Update Installer (about 20KB) and the device specific Update Agent, and one to be temporarily allocated upon running for the updatespecific data, to ensure start-to-fi nish integrity of the update install process.

vCurrent Mobile Update Installer is update-able over the entire device lifecycle. The Update Installer software itself can be quickly updated over the air, allowing it to be embedded during the manufacturing process and upgraded remotely and transparently, as required, throughout the life of the device.
