I think mobile_id is what you are looking for which has a mobile attributes lookup table that goes with it. There may be limitations of using mobile_id and user_agent at the same time.
Device reports are based on user agent strings which get resolved by Device Atlas to the device information.
Adobe Analytics currently uses data from DeviceAtlas to decode user agents into human-friendly device names In that case you would need to look at the column header User_Agent translate them to device Name etc.
