Purpose: For action

Body: The GSMA, one of the Market Representation Partners of 3GPP, have a project concerning End to end Network Slicing under the Network Group (NG). The project aims to identify potential gaps in standards and input recommendations to the related organisations toward the realisation of Network Slicing architecture designed from an End-to-End (E2E) perspective. This E2E notion means network slicing capabilities need to be integrated across the different domains (e.g., device, access network, core network, transport network and network management system), so that Service Level Agreement based on customers’ requirements can be guaranteed. 

The GSMA NG would like to inform related organisations that the GSMA Whitepaper NG.127 “E2E Network Slicing Architecture” has been published on gsma.com at :  
https://www.gsma.com/newsroom/resources/ng-127-e2e-network-slicing-architecture-v1-0/ . 

The intention of this whitepaper is to show guidance of the entire industry ecosystem; for operators, vendors and service providers to be able to consider common solutions of network slicing which have not been fully defined yet.
 
The scope of this whitepaper is to provide the description of: 
1. Blueprint of E2E Network Slicing Architecture,

2. Technology aspect,

3. Ongoing SDOs and open-source projects, 
which are snapshot based on current status of these standardization activities, typically activities of the 3rd Generation Partnership Project (3GPP) Release 17. 

ACTION
The GSMA NG kindly asks related organisations to take our whitepaper into consideration for their standardisation work on E2E network slicing as well as provide feedback on our whitepaper.
