For devices running Android 12 or higher, Android provides support for 5G network slicing, the use of network virtualization to divide single network connections into multiple distinct virtual connections that provide different amounts of resources to different types of traffic. Android 12 introduces the following 5G enterprise network slicing capabilities, which network operators can provide to their enterprise clients:. For enterprises who provide fully managed company devices to their employees, network providers can provide them with one or more active enterprise network slices where traffic on the company devices are routed to. For enterprises using the work profile solution, Android 12 allows devices to route the traffic from all apps in the work profile to an enterprise network slice. The work profile solution provides an automatic level of authentication and access control that enterprises require to ensure that only traffic from enterprise apps in the work profile are routed to the enterprise network slice. Apps in the work profile don't need to be modified to explicitly request the enterprise network slice. Android 12 introduces support for 5G network slicing through additions to the telephony codebase in AOSP and the Tethering module to incorporate existing connectivity APIs that are required for network slicing. The Android telephony platform provides HAL and telephony APIs to support slicing based on network requests filed by the core networking code and 5G slicing capabilities in the modem.
