The need for A3 in open RAN

The RAN will become the biggest user of analytics, AI and automation (A3) in the telco and its virtualisation/disaggregation in the open RAN specifications enables a range of vendors to participate in the provision of A3.

The diagram describes the major groupings of network requirements found during research into r/xApp deployments – the size of the box denotes the number of use cases in each requirement area and the colors describing their needs for more or less sophistication in intelligence and automation.

The darker colored groups have the most sophisticated requirements – with more functions requiring machine learning (ML) and more complex automations (including nested loops and cross-domain requirements).
