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.

Enhancement

1

Ahila

Wipro

SO, SDN-R, New Policies

2

Activate, Deactivate flows support in external  RAN NSSMF

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

Enhancement

2

Yogendra

Aarna Networks

Yes

 Deferred to K-release

3

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 in NSI/NSSI selection based on this criteria.

4

Core, RAN Endpoints Discovery at NSMF

Hardcoded RAN and CN endpoints are used in the previous releases. Discover the Core and RAN endpoints from the network and fed it to TN NSSMF

Deferred to K-release

5

NSI Selection based on the coverage Area

eMBB or mMTC like service parameters. with coverageArea more than what is already supported in a suitable existing and shareable NSI  Sharing allowed

Enhancement

Ahila

Wipro

SO, OOF

6

IBN based E2E Slicing

Communication service request is given as business intent and it should be integrated with the existing E2E slice flow.

Populate sNSSAI in the UUI to complete the pending actions

Enable the user to select the sNSSAIs in UUI to complete the pending actions pertaining to that Slice

New

2

Proposed by Yogendra. 

02-11-2021: Received a comment from Lin and Alessandro that this feature is not significant in the market. so deferring this requirement for now

RAN Slicing

1

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

 Completed

2

Instantiation of RAN NFs and initial configuration (stretch goal)

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

Ahila

Wipro

CPS-TBDMT

Yes

 Descoped, as this interface is not possible for primary yang model with the current architecture

Core Slicing

1

ETSI aligned Core NSSMF

Leverage Core NSSMF to be in an alignment with SOL-005 APIs while supporting the existing Non-ETSI (3GPP) interfaces

New
