    • Working on SME & DME integration & improvements
  • Continue maturing the A1-Policy Controller function (ref ONAP) - including a potential new NBI (v3) to achieve R1 alignment
    • Current API will be maintained but deprecated for several releases to come.
    • Making slow but steady progress.
