Summary

Recommendation ITU-T Y.3323 defines the design principles and requirements of soft network architecture
for mobile (SAME), i.e., flexible traffic steering, virtualization of SAME network functions, SAME network slice,
and separation of control function and forwarding function. Its scenarios and problem statements are
introduced in the appendices.
SAME is a mobile packet core network, which bridges current legacy mobile network towards future networks.
Though SAME does not aim to cover key requirements of IMT-2020 core network, these key requirements of
SAME may be adopted in IMT-2020.
