Moving to a software-based, disaggregated multi-vendor solution that is built on open modular solutions with standards-based Interoperability enables service provider agility and innovation. Network solutions also need to natively incorporate automation, Machine Learning (ML) and Artificial Intelligence (AI).
The first phase of the SDMN solution blueprint uses the 3GPP Option 2 Split, where the virtualized Central Unit (vCU) resides in a central data center with the Distributed Unit (DU) and the Radio Unit (RU) co-located or integrated within a small cell.
This briefing is intended to be used for architecture validation, proofs of concepts (POCs), demonstrations, and functional and interoperability testing.
The objectives of the briefing include, but are not limited to:
- Develop integrated solution/vision for the Software-Defined Mobile Network (SDMN).
- Highlight the benefits of an Open virtualized Radio Access Network (Open vRAN)
- Incorporate OEM partner solutions where required/desired for end-to-end system.
- Evaluate and verify the SDMN solution features and performance.
- Develop an understanding of SDMN operational aspects.
- Conduct customer demos.
- Enable SDMN POCs.
- Understand risk profiles.
More about the SDMN blueprint:
The 3GPP Option 2 Split enables centralization of the PDCP layer and a centralized RRC/RRM. This split is very latency tolerant enabling distances of tens of kilometers between the vCU and vDU and can be implemented using non-fiber transport.
The vCU is provided by Altiostar and the indoor small cell (RU+DU) is provided by Sercomm. Cisco provides their Control and User Plane Separation (CUPS) based virtualized Evolved Packet Core (vEPC), the converged SDN transport network, the Cisco Virtualized Infrastructure Manager (CVIM) for infrastructure and cloud lifecycle management and UCS-C servers for the NFV infrastructure.
The blueprint uses two HSS solutions that can be used alternatively — NetNumber’s on-premise HSS and WG2 cloud-hosted HSS. This blueprint also includes WG2’s cloud-based IMS solution.
The first phase of the solution blueprint consists of three major components:
- CVIM Full POD – Central DC: The Full POD is mainly used to host mobile core, automation and orchestration, and auxiliary components:
- High and low-level orchestrators
- vRAN EMS
- CVIM Micro POD – Regional DC: The Micro POD is mainly used to host vCU, but other workloads such as SAEGW-U and mobile edge computing (MEC) apps may also be tested.
- Radio and UE: Band-3 LTE Sercomm radio is used for over-the-air testing using Samsung Galaxy S20 User Equipment (UE). The test UE is accessible via a remote desktop application.
What is a briefing?
A scheduled event with a WWT subject matter expert — typically via a live Webex — where we present an overview of specific topics, technologies, capabilities or adoption trends. Your attendees are allotted time for Q&A to pose questions specific to your organization. This is a complimentary service.
Who should attend?
This briefing is designed for, but not limited to, the following personas within Tier 1, Tier 2 and Tier 3 service providers:
- Solution/Principal architects
- Portfolio managers
- Technical engineers
- Advisors and consultants
How WWT can help
Service providers need help accelerating the integration and adoption of innovative technology solutions that make up a Software Defined Mobile Network to fully realize their benefits and maximize ROI.
WWT can help service providers more rapidly deploy SDMN within their network by providing fully-integrated cloud-based, virtualized solution blueprints that operators can leverage to accelerate 4G and forge a clear path toward broader 5G adoption.
Our Next-Generation Factory Model allows operators to move from innovation to validation and deployment more rapidly than in the past. It accelerates time to revenue by validating complex, multi-vendor solutions with speed in our ATC, integrating them at scale in one of our global integration facilities.
