Service intelligence doesn't need to come from the core; it may be far out in the edge. At the RU, there is packetized data ready for transmission over eCPRI to the DU. In this webinar <https://www.lightreading.com/webinar.asp?webinar_id=1656> (@6:07), there's a bit of a projection about use of service intelligence.
