The descriptions on the planes are as follows:
• 5G Application and Service Plane
The 5G Application and Service Plane (5G-ASP) enables a service-aware behaviour of 5G network in a
programmatic manner via various APIs which exposes softwarized network capabilities. It consists of
application & service plane management support/softwarization/orchestration functional component that
interacts with 5G multi-layer management function and multiple 5G application functional components that
interacts with 5G Control Plane via standard interfaces.
– ASP Management Support, Softwarization, & Orchestration

The ASP Management Support, Softwarization, and Orchestration (ASP-MSSO) softwarizes and orchestrates
5G applications with the support of Multi-Layer Management.
It includes applications code repository management, application lifecycle management (creation,
modification, and deletion), performance monitoring of applications to meet SLA requirements, detection,
rd
isolation, and correction of application faults, and security management of 3 party applications
(authentication and identity management).
It also provides the capabilities for provisioning of ASP resources (resources that are used to run ASP
applications) based on the requests received from the Management Plane. It coordinates provisioning of ASP
service resources and network resources in Resource Layer in cross-layer manner and also performs atomic
transactions to ensure the integrity of the requested provisioning service. ASP-MSSO provides capabilities
for managing of ASP resources. It manages the capacity and performance related to each ASP service. ASP-
MSSO obtains resource quality of service information in order to measure and record key performance
indicators (KPIs) for the ASP service. Capacity for an ASP service is allocated or de-allocated based on these
KPIs.

In case when virtual networks have been created by Softwarization capability, they are built with the support
of the Control Layer, and may use the same Application Layer, or to attach an ASP instance to each virtual
network.
