Where do OTA updates actually come from?

For example let's say you own a Manufacturer ABC cell phone, have it running on Service Provider DEF towers, but are using MVNO XYZ to provide service.

When you perform an OTA update, who is actually providing the bits (the actual ROM) and who is transmitting it to you? I guess that's really 2 questions.
