This presentation is inspired in “the yellow book” which is a classical reference in IMS. I´d like to thank the authors of that yellow book (Gonzalo Camarillo and Miguel Martín) for their comments on how to teach IMS to my engineering students. All the same I´d like to thank my colleague and friend Javier Sanz-Blasco (now in Telefonica) for his inspiring suggestions on how to handle the next generation networks concepts.
