OTA programming is to realize the remote control of the data of the mobile device or equipment through communication and use the wireless network to update the database to obtain the latest version.
What is Over-the-Air Programming?
Over-the-air (OTA programming) is a method of distributing new software, configurations, and even updating encryption keys to devices. An important feature of OTA is that a central location can deliver updates to all users, who can approve or reject OTA updates. However, once you agree to the update, you accept all the content changes of the update, and the update will be applied immediately.
Application areas of over-the-air programming:
The field of mobile content also includes the over-the-air provision of services, over-the-air configuration or over-the-air parameter management, or provision of necessary settings for mobile phones to enable them to access services, such as WAP or MMS, and over-the-air programming applications. A wireless programming system should be able to accommodate a wide variety of hardware, operating systems, applications, and firmware.
With more and more applications and functions on mobile phones, OTA configuration has become more and more important. Through SMS, the data in the SIM card can be updated by OTA. Necessary settings for distributing software updates to the mobile phone and accessing services such as WAP and MSS can be updated as well. OTA messages can provide remote control of services, subscription activation, personalization, and programming of the handset. Various standardization bodies have been established to help develop, oversee and manage OTAs.
With the development of the Internet of Things, OTA has been applied to the Internet of Vehicles. With OTA technology, software and other applications can be automatically updated to evaluate distances and times, so that car users can save on the time and cost of vehicle trips. As long as the vehicle is within the area covered by the wireless network, the user can update the navigation software independently.
By establishing a connection with the vehicle through the honeycomb network, after installations and updates are completed, the server is notified so that control and maintenance of the vehicle can be updated.
What is the method of over-the-air programming?
Depending on the implementation, the delivery of the OTA software can be triggered upon specific actions, such as a call to the service provider's customer support system or other dialable services, or it can be performed automatically. This is usually done in the previous way to avoid unexpected service downtime, but also means that customers need to proactively call. Some vendors send SMS text messages to all customers asking them to call a service number to receive software updates. The solution allows operators to manage wireless device functions, including renumbering handsets, updating handset settings, applications, and user data, and adjusting PRLs to manage cost structures.
To provide parameters in a mobile device OTA, the device needs a provider-client that can receive, process, and set parameters. For example, a device management client in the device may receive and provide application and connection parameters. In general, OTA means using an over-the-air mechanism to deliver provisioning data or update packages for firmware or software updates to the mobile device, which saves the user from having to go to a store or service center to obtain applications, parameter changes, and firmware or software updates. If users needed to rely on a service center for OTA updates, they would have to go to the center and use a computer to connect to the device to change the configuration or add software to the device, etc.
