The 5G technology is a revolutionary technology, which will offer an “unlimited wireless world interconnection” (Badoi et al. in Wirel Pers Commun 57(3):441–464 2011. doi:10.1007/s11277-010-0082-9; Prasad 2014) and a large type of services to a vastly number of users, while using a high performance terminal. These services will most probably be provided to the users as cloud based services, with different Quality of Services (QoS) characteristics. More exactly, based on the user subscription and on the required service, the user will be served with a given QoS. Each type of QoS services class will be assured by a 5G virtual network, having a one-to-one QoS class versus 5G virtual network correspondence. In this context, the virtualization and scheduling methods will play an important role regarding the ability to provide such services in 5G networks. In this paper we present the virtualization concept within 5G networks, while also describing the existing work conducted until now in wireless networks and Future Internet fields. Two virtualization methods are also presented in this paper, based on the spectrum sharing principle used in the Cognitive Radio networks (Badoi et al. in Wirel Pers Commun 57(3):441–464 2011. doi:10.1007/s11277-010-0082-9) and based on partition principle used in Future Internet (Nejbati et al. 2012). A combination of these two methods should offer a better granularity of 5G networks virtualization, with the price of an increased complexity.
