I am implementing a carrier application (https://source.android.com/docs/core/connect/uicc) that manages carrier configurations.
One part is to configure the T-ADS (Terminating-Access Domain Selection). This includes:
Whether it is supported
The T-ADS timer
Whether network remembers last domain
Whether it prefers PS or CS
Usually, the stuff like this can be found in CarrierConfigManager (https://developer.android.com/reference/android/telephony/CarrierConfigManager) configuration keys, but I could not find anything related to T-ADS. Also tried to check generally what is in docs related to it, but ended up without results.
