Due to the complexity of most modern operating systems and the frequency with which they are updated, all leading manufacturers provide Over-the-Air (OTA) software updates for their tablets, smartphones and even cars.

It may take several months between devices leaving the production line to reaching consumers’ hands but users demand the latest updates to get access to new features. In today’s connected world, software updates are a must-have feature for any type of consumer electronics device, from low-end smartphones to high end tablets by way of M2M devices such as cars and set top boxes (STB).

In this SlideShare, Red Bend Software shows you how to manage these updates easily and effectively, providing best practices in rolling out OTA software updates.

  • This slide provides a partial list of suggested test guidelines for evaluating FOTA updating solutions, for example :Silent download – Verifies that the device supports Silent Download capability and not only the download approved by the consumerAbility to manage large FOTA update packages – Verifies that the device is able to process a large FOTA update packageServer notification during a phone call – Verifies the device behavior when it receives an update notification during a voice call.Corrupted update package – Checks the device successfully detects an incorrect or corrupt update package before proceeding with the update process. The device should gracefully manage it and notify both the user and the back-end management system.Postpone/Accept/Reject update – Verifies that the device allows the user to postpone, accept, or ignore the software update. In case of postpone, it should be able to set a reminder when to activate it again. In case of accept, it should start the update process. And in case of ignore, it should cancel the process.Battery removal during the update process – Verifies that the FOTA client can handle battery removal during the update process, simulating a loss of power due to battery drain-age or battery falling out. This test can be performed a few times during the update process, for example every 10-20% of the elapsed update time.Mobile originated a voice call during the update process – Verifies the behavior of the device when a voice call is originated by the user during the update process.
  • The Third stage is optimizing the user experience,One of the important factors in a successful device update strategy is to understand how to make this process as easy and quick as possible for the users. In the case of getting a software update by a push method, meaning that the back-end management system is initiating the FOTA update campaign. The user has the flexibility to decide when to perform the update and, if the decision is to apply the update now, it means that if it was planned correctly in only two clicks the device will have a new version. Since some mobile subscribers are hesitant to install new versions, the way to remove this barrier is to ensure that the update message comes from a trusted source, such as the operator or the OEM. In this message, it is important to provide customers with a brief explanation of the content of the update, the benefits to the user for performing the update, and how much time it is expected to take.One of the methods to improve the user experience is by reducing the time needed to perform the updates, because during this time mobile subscribers cannot use their device.The proposed method is updating the device firmware in the background while the device is fully operational.In this approach, all of the software on the device must be available for the user, while in parallel the FOTA client updates the software on flash memory.
