  In 5G research, it is traditionally assumed that vertical industries (a.k.a
verticals) set the performance requirements for the services they want to offer
to mobile users, and the mobile operators alone are in charge of orchestrating
their resources so as to meet such requirements. Motivated by the observation
that successful orchestration requires reliable traffic predictions, in this
paper we investigate the effects of having the verticals, instead of the mobile
operators, performing such predictions. Leveraging a real-world, large-scale,
crowd-sourced trace, we find that involving the verticals in the prediction
process reduces the prediction errors and improves the quality of the resulting
orchestration decisions.
