EN In this paper we give an overview of an open disaggregated network architecture based on an Open Radio Access Network (O‑RAN), including the current work from standards bodies and industry bodies in this area. Based on this architecture, a framework for the automation of xApp development and deployment is proposed. This is then aligned with the key concepts described in ITU‑T in terms of the evolution, experimentation, and adaptation of controllers. The various steps in such an aligned workflow, including design, validation, and deployment of xApps, are discussed, and use case examples are provided to illustrate further our position regarding the mechanisms needed to achieve automation.
