4.7 Coordination with management systems of non-3GPP parts

When providing an end to end communication service, the network may use non-3GPP parts (e.g. Data centre network (DCN), Transport network (TN)) in addition to the network components defined in 3GPP. Therefore, in order to ensure the performance of a communication service according to the business requirements, the 3GPP management system has to coordinate with the management systems of the non-3GPP parts (e.g., MANO system) when preparing a network slice for this service. This coordination may include obtaining capabilities of the non-3GPP parts and providing the slice specific requirements and other requirements on the non-3GPP parts. Figure 4.7.1 illustrates an example for the coordination with management of TN part (e.g., directly or via MANO system).

The 3GPP management system identifies the requirements on involved network domains, such as RAN, CN and non-3GPP parts of a slice by deriving them from the customer requirements to the services supported by the network slice. The derived requirements are sent to the corresponding management systems. The coordination may also include related management data exchange between those management systems and the 3GPP management system.
