E2E Slicing Solution
1
Support for mMTC, uRLLC Slices
eMBB slice type is supported in the previous release. This requirement is to accommodate the modification in the existing system to support mMTC and uRLLC performance requirements.

Activate, Deactivate flows support in
external NSSMF
external RAN NSSMF
To support the activate and deactivate actions in E2E Network Slicing with External NSSMFs (option2). Currently, instantiation and termination are supported.

Capacity based NSI/NSSI Selection
In case of shared scenario (reuse existing slice), NSI/NSSI can be shareable only if sufficient resources are available in the network. OOF should return the solution for NSI/NSSI selection based on this criteria.

cm-handle registration with CPS-DMI Plugin - Integration
cm-handle should be registered with CPS for every RAN NF instance. Karaf feature to do the registration is completed in I-release, integration with CPS is planned for J-release

Instantiation of RAN NFs and initial configuration
RAN Network Functions (CUCP, CUUP, DU) are assumed as pre-instantiated and pre-configured since Guilin release. This needs to be created/instantiated as VNFs/CNFs
