ITU-T Focus Group IMT-2020 Deliverables 3

Control Plane Policy Management

The Control Plane Policy Management (CP-PoM) functional component provides capabilities to define, store
and retrieve policies that apply to CP-services. Policies can include business, technical, security, privacy and
certification policies that apply to CP-services and their usage by IMT-2020 applications.

Some policies can be general and apply to a CP-service irrespective of the IMT-2020 application concerned.
Other policies can be specific to a particular IMT-2020 application.

Control Plane Multi-Plane Management Orchestration Support
The Control Plane Multi-Plane Management Orchestration Support (CP-MMOS) functional element provides
an internal interface to the Multi-Plane Orchestration support functional element in the MMOS functional
component for requesting and receiving management operations and associated information for multi-layer
orchestration specific to control layer management.

8.4 Application and Service Management Functional Component

Service management monitors end-to-end network service utilization aspects such as bandwidth, latency etc.
in response to customers request. Service management is established by BSS/OSS in response to customer
request. OSS assembles services and assures network performance to customers. BSS manages accounts and
payment with customer support and service modification. Customer KPI is established and managed through
service management. It enables the creation, operation, and control of multiple dedicated communication
service networks running on top of an IMT-2020 infrastructure. A unified end-to-end service management
ensures compatibility and flexibility of the operation and management for IMT-2020.

Network management only needs to forward the current status report of network management systems to
BSS/OSS in order to meet customers’ needs. Service management shall also be included in management. This
principle shall remain the same with the ongoing softwarization trend. There is definitely a need for an
interface between BSS and OSS in order to exchange the information within the management plane.
Therefore, service management should be included in management with interface to BSS/OSS for network
service management.
The following sub-clause describes detailed management functionality in the Application and Service Plane
Management (ASPM) functional component. Figure 10 shows its functional elements.
