5G USE CASES & REQUIREMENTS IN R9 (Istanbul)
| USE CASE / REQUIREMENT | DESCRIPTION | WIKI LINK |
|---|---|---|
| 5G SON Use Case | SON (Self-Organizing Networks) functionality is an essential part of existing 4G mobility networks, and will be even more critical for 5G. SON enables automation to improve network performance and efficiency, improve user experience, and reduce operational expenses and complexity. The objective of the OOF-SON (new name for OOF-PCI) use case is to develop an ONAP-based SON platform using the ONAP Optimization Framework (OOF). We have taken a phased approach since SON is complex, and SON for 5G is still evolving. We started with the Physical Cell Identity (PCI) optimization SON use case in Casablanca, then added some centralized Automated Neighbor Relations (ANR) aspects in Dublin. In Frankfurt, we addressed some enhancements such as basic CM-notify handling (as preparation for O-RAN alignment), adaptive SON, etc. In Guilin, we introduced use of AI/ML by onboarding an offline-trained ML-model to ONAP which will provide additional inputs to PCI optimization based on historical PM data, and stabilized the functionality in Honolulu. In Istanbul, we will align FM messages with relevant standards, move to new 3GPP NRM-based yang models and leverage CPS for RAN configuration. | R9 5G SON use case |
| End to End Network Slicing | 5G Network Slicing is one of the key features of 5G. The essence of Network Slicing is in sharing network resources (PNFs, VNFs, CNFs) while satisfying widely varying and sometimes seemingly contradictory requirements to different customers in an optimal manner. Same network is expected to provide different Quality of Experience to different consumers, use case categories and industry verticals including factory automation, connected home, autonomous vehicles, smart cities, remote healthcare, in-stadium experience and rural broadband. An End-to-End Network Slice consists of RAN, Transport and Core network slice sub-nets. This Use Case intends to demonstrate the modeling, orchestration and assurance of a simple network slice (e.g. eMBB). While 3GPP standards are evolving and 5G RAN and core are being realized, this Use Case will start with realizing an E2E Network Slice with a simple example of a 5G RAN, Core and Transport Network Slice sub-nets. It will also align with relevant standard bodies (e.g., 3GPP, ETSI, TM Forum) as well as other open initiatives such as O-RAN where relevant, w.r.to both interfaces as well as the functional aspects. | R9 E2E Network Slicing use case |
Smart Operator Intent Translation in UUI based on IBN - R8 5G Slicing Support | A lightweight and high-cohesion Nature Language Processing (NLP) function is proposed to add in the UUI project, in order to translate the network operation engineers’ text/voice intents to the suitable slicing parameters quickly and decrease the manual configurations. | |
| Support for Vertical Industry | Support for Vertical Industry. Intent framework is a system that helps to implement and operate networks that can improve network availability and agility. It takes a high-level business goal (intent) as input, converts it to the necessary network configurations and applies the network changes via network automation and/or network orchestration. Continuously monitoring the status of the network under control, the system validates in real time that the intent is being met, and can take corrective actions when desired intent is not met. | |
| Intent Based Networking | Support for Intent Framework and Intent Modeling. (add description) | |
| ONAP/3GPP & O-RAN Alignment: A1 Adapter and Policy Management Extension | A1 Adapter and Policy Management Extension. R8: 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. R9: This feature requirement enhances A1 Policy Management for the O-RAN A1 interface capabilities provided in Rel 6, 7 & 8. Work will continue by extending & evolving support for using A1 Policies to manage 5G RAN elements by providing intent based policies for optimization of the RAN network performance. Planned enhancements for Rel 9 include support of new A1 interface versions to align with new versions & improvements to O-RAN alliance specifications. | |
MAJOR USE CASES & REQUIREMENTS IN R9 (ISTANBUL)
| USE CASE / REQUIREMENT | DESCRIPTION | WIKI LINK |
|---|---|---|
| Certificate Management Protocol v2 | 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). R9 Certificate Management Update. | R9 CMP v2 |
| ETSI Alignment | ETSI Alignment Use Case to support CNF orchestration. Driven from the ETSI SOL 00x series of standards. | R9 ETSI-Alignment Use Case |
xNF (PNF/VNF) 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. | |
| Bulk PM/ PM Data Control | Bulk PM / PM Data Control Improvements PM data collection control provides 5G network operators with a dynamic and more efficient way to configure performance measurement collection on a selected subset of PNFs/VNFs in the network and complements the existing PM data collection and processing capabilities in ONAP/DCAE. An initial version has been delivered in Rel 6 (REQ-129) then enhanced in Rel 7 (REQ-381). Planned enhancements for Rel 8 intend to improve the (PMSH) subscription management about subscription update. | |
| Scheduling Optimization | ONE area in Change Management focusing on schedule optimization. Schedule optimization - automatically discover change schedule based on service constraints & operational constraints. | Scheduling Optimization for R9 Use Case |
