The authors discuss 3GPP EPS mobile network evolution as a whole, analyzing specific architecture properties that are critical in future 3GPP EPS releases. In particular, they discuss the evolution toward a "network of functions," network slicing, and software-defined mobile network control, management, and orchestration.
1) Network Architecture: In REF , the authors introduce a network slicing architecture towards 5G.
