5G-MP can delegate some management operations, specifically those which require intensive exchange of
data with 5G-CP to be performed directly by 5G-CP (for example, autonomous management operations).
Delegated operations are performed by management support functions within each plane.

– Application and Service Plane Management
The Application and Service Plane Management (ASPM) provides management functionality for managing
resources of 5G-ASP. It includes FCAPS of resources in the application layer. It is also used in a cross-layer
orchestration driven by 5G-ASP.
5G-specific Application and Service Plane management includes applications code repository management,
applications lifecycle management (creation, modification, and deletion), performance monitoring of
virtualized applications to meet the SLA requirements, detection, isolation, , recovery of application faults
rd
and security management of 3 party applications (authentication, identity management).
– Control Layer Management functional component

The Control Plane Management (CPM) functional component includes management of resources used to
deploy control layer functions (hardware, software platforms, links connecting control plane with other
planes) in order to ensure high availability and scalability of CP, performance, fault and security management
of control traffic generated between CP entities and RP or ASP entities. It can bootstrap CP entities or their
components, monitor performance of CP entities in terms of reliability, utilization, detection, root cause
analysis, and correction of faults of CP; detection, isolation, and control of CP related traffic and
authentication and authorization management functionality of 5G-CP entities. The policy management can
include business, technical, security, privacy and certification policies that apply to CP-services and their
usage by 5G applications. The CPM also provides energy-aware the CP resource management.
– Resource Plane Management

Resource Plane Management (RPM) functional component is responsible for the management of physical
and/or virtual resources. RPM provides capabilities for discovering and bootstrapping of virtual and physical
resources to make them ready for operation. RPM functional component include support for FCAPS and RP
orchestration (for example coordinated resource reconfiguration) that is provided by Multi-Plane
Management Orchestration (MPMO) functionality. MPMO provides the capabilities for provisioning of RP
resources and RPM keeps track of the overall state of allocated and available resources of RP. It is also
responsible for managing the configuration relationship between virtual and physical control layer resources,
performance co-relation between virtual and physical control layer resources, and faults by considering the
relationship between virtual and physical control layer resources, and finally isolation, control of anomaly to
selected SDN network resource, and finally authentication and authorization of the network resources. By
providing the overall resource status information monitored as an input to RPM, energy efficient resource
management capability can be realized by, e.g., turning off of unused resources.
– Multi-Plane Management Orchestration

The Multi-Plane Management Orchestration (MPMO) provides functionalities for supporting the lifecycle
management of 5G application/network services across the entire 5G operator’s domain and orchestrates
multi-layer resource management. It coordinates management operations among application, control, and
resource planes, especially the relationship among virtualized and physical resources across multiple layers.
– External Relationship Management
The External Relationship Management (ERM) provides management functionality to interwork with external
management entities. It plays a role of the representative interface of 5G management toward the external
management entities such as MANO, 2G, 3G, and LTE OSS/BSS. Its main functionality includes abstraction of
5G management information, request/reply of management operations with external management entities,
external SDN policy management, data analytics, charging and DevOps operations.

It also provides another important management capability to interwork with 5G-MP in other domains. This
interaction allows inter-slice management and hierarchical/recursive 5G management capabilities for
scalability purposes.
