CONCEPT FOR 5G MOBILE NETWORKS
The 5G terminals will have software defined radios and modulation schemes as well as new
error-control schemes that can be downloaded from the Internet. The development is seen
towards the user terminals as a focus of the 5G mobile networks. The terminals will have access to different wireless technologies at the same time and the terminal should be able to combine different flows from different technologies. The vertical handovers should be avoided, because they are not feasible in a case when there are many technologies and many operators and service providers. In 5G, each network will be responsible for handling user-mobility, while the terminal will make the final choice among different wireless/mobile access network providers for a given service. Such choice will be based on open intelligent middleware in the mobile phone. Now, we will go through all OSI layers (Fig. 1) in the 5G mobile terminal design (Fig. 2).
