Mobile Phone Firmware Upgrades

As Mobile Phones Add Features, Firmware Becomes More Complex.

Over the last several years, mobile telephones have undergone a transformation from relatively simple voice-based handsets to more sophisticated multimedia communication devices, and they now commonly include text messaging, cameras, web browsers, conferencing capabilities and other sophisticated features.

In order to provide these more sophisticated features, these devices now require increasingly complex mobile phone firmware. It is this firmware that controls the operations of the mobile phones. The growing complexity of technology, however, presents a significant challenge to mobile handset manufacturers and mobile telephone carriers: the ability to ensure that the mobile phone firmware is of high quality and 100% reliable. Given the volume of mobile handsets shipped - more than 600 million units are expected to ship in 2004 -and the diverse conditions in which they are used, as technology complexity increases, the likelihood of mobile phone firmware defects causing an operating malfunction increases.

Firmware Over the Air (FOTA) Technology Enables Cost Effective Mobile Phone Firmware Upgrades.

To address the growing challenge of providing higher quality and more reliable mobile phone firmware, and eliminating expensive recalls, while at the same time meeting aggressive time-to-market demands, a more effective technology known as firmware over-the-air (FOTA) mobile phone upgrading is gaining broad acceptance in the mobile telephone industry. FOTA upgrades enable mobile device manufacturers and mobile network carriers to remotely update the mobile phone firmware wirelessly. That is, it can upgrade the mobile phone's firmware even when the phone is already in customers' hands.

By using FOTA methods to upgrade mobile phone firmware and to patch flaws in the firmware originally installed on the handset, users no longer need to bring the handset to a service facility to upgrade the firmware on their mobile phone.

Delivering Firmware Upgrades Over the Air Enables Mobile Phone Personalization

In addition to delivering patches to fix faulty mobile phone firmware, the FOTA mobile phone update technology can be used to deliver new features and services to customers. Because this upgraded mobile phone firmware can be delivered to users without requiring them to bring their mobile device to a service facility to reflash the memory with new firmware or to purchase a new handset, carriers can conveniently deliver firmware with new services to individual users' handsets, in effect personalizing the handset to meet the particular needs of an individual user. This has the advantage of enhancing customer loyalty and it provides opportunities for carriers to generate additional revenue per subscriber.
