Smart Operator Intent Translation in UUI based on IBN - R8 5G Slicing Support

A1 Adapter and Policy Management Extension.

This requirement enhances the A1 interface capabilities provided in Rel 6 as part of  5G/ORAN & 3GPP Standards Harmonization requirement ( REQ-38) and extended in Rel 7 with the introduction of A1 policy management.   O-RAN has defined A1 interface specification in the context of the management of 5G RAN elements to provide intent based policies for optimization of the RAN network performance. Planned enhancements for Rel 8 include support of new A1 interface version in alignment to O-RAN alliance and common logging/audit.

The PNF Plug and Play Use Case allows a PNF to register with ONAP using a pnfRegistration VES Event. This is expected to be used for installation & commissioning a network that is to be managed by ONAP. When this event is received, the PNF Registration Handler (PRH) processes this event to complete the registration by updating the corresponding A&AI entry for the expectant PNF. The PRH was developed specifically for this use case. Once registered, ONAP can interoperate with the PNF and perform LCM or FCAPS (OA&M) operations in addition to other actions. This Use Case was originally started in in R2 Beijing and functionality has been continually improved since then.

The Certificate Management Protocol (CMP) is an Internet protocol used for obtaining X.509 digital certificates in a public key infrastructure (PKI). It is described in RFC 4210 and is one of two protocols so far to use the Certificate Request Message Format (CRMF), described in RFC 4211, with the other protocol being Certificate Management over CMS (CMC), described in RFC 5273. An obsolete version of CMP is described in RFC 2510, the respective CRMF version in RFC 2511. CMP messages are encoded in ASN.1, using the DER method and usually transported over HTTP. CMP (Certificate Management Protocol) Server & Client (completed in R6)

The Configuration Persistence Service is a Common Data Layer Service providing database functionality to persist network element run-time information. CPS will perform key DB operations such as syncing data with xNFs. CPS enables OSS configuration, optimization and E2E LCM operations. It will be a new Platform Component in R8.

xNF Software Upgrade

PNF Software Upgrade enhancement

In Rel 6 (REQ-84) and Rel 7 (REQ-324), PNF sw upgrade requirement in ONAP has progressed covering both with/without schema updates. A schema update in relation to a xNF software upgrades is a routine for network upgrade to support new xNF features, improve efficiency or increase xNF capacity on the field, and to  eliminate bugs.  This use case provides to ONAP an advantage in orchestrating and managing the Life Cycle of a Network Services in-line with business and service objectives. In Rel 8, the feature will be enhanced with PNF sw version management during sw upgrade procedure.
