Reference Points over SDN  R1: Access link  SDN-based configuration/interaction between infrastructure and wireless link  R2: User & terminal authentication, subscription & terminal management  This reference point can be implemented as a control path from the access network to the corresponding operator  R3: Authorization, service management, user data connection, mobility support, accounting, location  The SDN controller can configure the underlying network for user authorization (e.g. adding MAC to APs), managing mobility (e.g. reconfiguring forwarding path per user), accounting (e.g. counters per forwarding table)  Possible extension of SDN concepts for configuration of heterogeneous access network.  R4: Inter-access network coordination and cooperation, fast inter- technology handover  SDN based forwarding state between different RANs  R5: Inter-operator roaming control interface  Inter-operator roaming plus access infrastructure sharing outside access network
