Standalone (SA) and Non-Standalone (NSA) 5G Architectures: The various paths to 5G revenues and profitability

by Seshadri Sathyanarayan Seshadri Sathyanarayan No Comments

A Telecom Transformation is underway. With 5G, a whole new generation of networks is being built to connect 50+ Billion Devices, creating more than a $12 trillion-dollar market opportunity for Mobile Network Operators. The road to 5G, it turns out though, isn’t a straight line. This leads us to a discussion of non-standalone architectures (NSA) and standalone architectures (SA). Here are the differences and benefits of NSA and SA and how MNOs can take advantage.

 

Differences Between NSA and SA 

The main difference of NSA (Non-Standalone Architecture) and SA (Standalone Architecture) is that NSA anchors the control signaling of 5G Radio Networks to the 4G Core, while the SA scheme connects the 5G Radio directly to the 5G core network, and the control signaling does not depend on the 4G network at all. NSA, as the name suggests, is a 5G service that does not ‘stand alone’ but is built over an existing 4G network. SA, on the other hand, allows completely independent operation of a 5G service without any interaction with an existing 4G core.

 

Per 3GPP TR 21.915, Two deployment options are defined for 5G: 

  1. The “Non-Stand Alone” (NSA) architecture, where the 5G Radio Access Network (AN) and its New Radio (NR) interface is used in conjunction with the existing LTE and EPC infrastructure Core Network (respectively 4G Radio and 4G Core), thus making the NR technology available without network replacement. In this configuration, only the 4G services are supported, but enjoying the capacities offered by the 5G New Radio (lower latency, etc). The NSA is also known as “E-UTRA-NR Dual Connectivity (EN-DC)” or “Architecture Option 3”.
  2. The “Stand-Alone” (SA) architecture, where the NR is connected to the 5G CN. Only in this configuration, the full set of 5G Phase 1 services are supported.

Non-Standalone Architectures for MNOs

The path that mobile network operators (MNOs) follow to 5G will depend a lot on how they plan to pay for that journey. During the deployment of 4G from 2010-2015, virtualization was not a mandate. Operators took many different approaches to deploying 4G architectures utilizing proprietary and virtualized solutions. With 5G, virtualization is a must. MNOs now have an opportunity to transform the way they build and operate their networks. 

For MNOs that are looking to deliver mainly high-speed connectivity to consumers with 5G-enabled devices, a non-standalone architecture (NSA) makes the most sense, because it enables them to leverage their existing network investments in transport and mobile core —rather than deploy a completely new end to end 5G network. This can be combined with efforts to reduce network operating costs by adopting virtualization and CUPS (Control and User plane separation) using software-defined networking (SDN). These initial steps toward 5G, enable MNOs to begin offering 5G services providing faster data speeds and capture additional revenue streams.

Benefits of 5G NSA:

  • deliver high-speed connectivity to consumers with 5G-enabled devices
  • leverage existing network investments in transport and mobile core

 

Standalone Architectures (SA) for MNOs

For some MNOs, however, who have their sights set on new enterprise 5G services such as smart cities, smart factories, or other vertical market solutions, a standalone architecture (SA) could make more sense. In this scenario, which 3GPP has now standardized, MNOs can build an entirely new fully virtualized 5G network that includes new radio access network, new transport network, and new 5G mobile core and edge networks – standing alone and separate from their existing 4G and legacy networks. 5G standalone architecture is a fully virtualized, cloud-native architecture (CNA) that introduces new ways to develop, deploy, and manage services. CNA includes concepts of microservices and service-based interfaces that greatly simplify services, dramatically reducing the cost of operation and speeding up the introduction of new revenue-generating services. With 5G SA, the distinct advantage here is end-to-end support for 5G speeds and services. And the true promise of 5G is enterprise-driven revenue – it changes the business model from consumer-driven to enterprise-focused opening up entirely new use cases and revenue streams.

Benefits of 5G SA:

  • MNOs can launch new enterprise 5G services such as smart cities, and smart factories
  • It is fully virtualized, cloud-native architecture (CNA), which introduces new ways to develop, deploy and manage services
  • The architecture enables end to end slicing to logically separate services
  • Automation drives up efficiencies while driving down the cost of operating the networks. 
  • By standardizing on a cloud-native approach, MNOs can also rely on best of breed innovation from both vendors and the open-source communities 
  • By choosing a cloud-native microservices-based architecture, MNOs can also decide on a variety of deployment models such as on-prem private cloud, public cloud, or hybrid to meet their business objectives

 

The Future of 5G Includes NSA and SA

It’s worth noting that NSA and SA aren’t an either/or proposition, but more of a “sooner or later” consideration. MNOs that begin with NSA can gradually add or migrate to SA over time. What we’ve seen at Affirmed from early 5G adopters are primarily NSA deployments as MNOs compete for the bragging rights (and the competitive advantage) of being the first to offer 5G speeds. These MNOs were typically the first to adopt 4G/LTE technologies as well, and so are fairly advanced in terms of network virtualization. Many of them are still using Affirmed’s solution as their virtual Evolved Packet Core (vEPC) solution. One of the advantages of Affirmed’s NSA-based solution is its ability to handle both 4G and 5G-based traffic as MNOs transform their networks.

At some point, of course, NSA and SA will converge as MNOs move to a full 5G architecture. Recognizing that, MNOs would do well to look for a mobile core platform that can transition easily from non-standalone to standalone. Having a completely virtualized 5G architecture will offer MNOs the flexibility to migrate select functionality of their existing NSA solution to the 5G core platform over time, as new 5G services are enabled, allowing them to monetize their investment gradually rather than go all-in and hope to recoup their costs later.

With a clear path to evolving their networks from NSA to SA, Mobile Network Operators can win the race to revenues by operating their networks at webscale. Learn more about our 5G core solution.

4 Key Capabilities for a 5G Slice Management Tool

by Adam Dorenter Adam Dorenter No Comments

No matter how you slice it, your slice manager matters a lot

If you were to ask mobile network operators what keeps them up at night, “5G slice management” probably wouldn’t be their first answer. Or their second, third, fourth… well, you get the point. The fact is that slicing is just a very small slice of 5G rollouts at first, with operators deploying only a few 5G slices initially: one for consumers, another for enterprises, maybe a third for an MVNO partner, but nothing so elaborate that managing those slices becomes a cause for sleepless nights.

Operators who ignore 5G slice management altogether, however, could be in for a rude awakening. By 2023, 5G users are expected to make up about half of all mobile subscribers. When that happens, operators will go from a few slices to a few hundred and, eventually, a few thousand. There will be slices for every app (e.g., Netflix, Facebook, YouTube), for every enterprise, and even for every application within an enterprise (e.g., manufacturing floor sensors, delivery vehicles, virtual private networks, videoconferencing). And managing all those slices will be unmanageable without an automated slice management tool.

Now that we’ve got you thinking about 5G slice management, the question is What should you look for in a slice manager? It ultimately comes down to four key capabilities:

Operational Agility

When 5G ramps up, operators are going to need to create slices quickly. Think sushi chef fast. So, their slice manager has to support a DevOps framework that allows them to create, spin up, iterate, and spin down slices dynamically to meet rapidly changing subscriber demands. Ultimately, slices will define the services you sell; the more slices you have, the more revenue streams you’ll have coming into your business.

Support for Virtualization

It’s a given that any operator implementing 5G capabilities will already be pretty far down the virtualization/container path. 5G slice management needs to support a virtualized environment, which brings to the fore unique concerns. For example, how do you measure NIC bandwidth, CPU, memory, and disk space on virtualized hardware? And how do you prioritize and balance traffic when you only have a single rack of virtualized servers in an edge deployment? The slice manager needs to be able to capture these metrics and re-balance or re-tune traffic in as close to real time as possible.

Service Optimization

Conserving physical resources is important, but so is serving up great subscriber experiences. Service optimization isn’t a new concept for operators, but it requires a new process in 5G. Today, operators optimize their services by drilling down into their data to pinpoint areas for improvement and then making manual adjustments accordingly. With a 5G slice manager, operators can now do this automatically. For example, a slice manager may detect congestion issues and decide to optimize Netflix videos through video compression. This traffic could be moved to an automatically instantiated slice in order to prevent impact to other services. A lot of these automated optimization capabilities will be enabled by a new network function defined in 5G, the network data analytics function (NWDAF).

Intelligent Orchestration

Orchestration in this sense refers to integration within an ecosystem of solutions. Some 5G vendors will try to sell operators a complete ecosystem based on their own technology and, yes, you would expect tight integration in such a case, but that’s not necessarily the best approach. Our approach is that best-of-breed is best because it gives operators more flexibility to pick and choose the right components. You might have a RAN slice manager from one vendor, a transport slice manager from another, and a core network slice manager from Affirmed. Choosing an orchestration solution built on open standards ensures that everything works together, allowing operators to perform service activation, subscriber provisioning, and slice management all from one shared platform.

The intelligent part of the intelligent orchestration refers to out-of-the-box, automated capabilities. Affirmed, for example, includes a lot of prebuilt content and wizards in its slice manager to help operators quickly and automatically set up, customize, and manage slices. The advantage here isn’t just speed but accuracy, as automated slice management reduces common, manual errors.

So, now that you know what to look for in a 5G slice manager—and that Affirmed can deliver those capabilities today with its UnityCloud 5G core solution—maybe you’ll rest a little easier. But don’t rest too long, or you could risk missing out on your slice of the 5G revenue pie.

UnityCloud Ops Brings Together Orchestration, Management, and Automation for Accelerated Digital Transformation in the World of 5G

by Sanjay Mewada Sanjay Mewada No Comments

Digital transformation is central to everything you do. It’s what determines how you build your network. It’s what sparks innovation in your business. It’s what will drive the great customer experiences of tomorrow. But without a new approach to orchestration, automation, and management, telco operators will never realize the full benefits of digital-driven initiatives such as 5G, multi-access edge computing, and the cloud.

Orchestration, automation, and management solutions support digital transformation by helping telco operators optimize processes and workflows, simplify network operations, accelerate service creation, ensure quality and reliability, and reduce operational costs. This becomes even more important, especially as the deployment of 5G and multi-access edge computing (MEC) accelerates. Despite the fact that many vendors offer orchestration, automation, and management solutions today, these solutions fail to deliver true digital transformation under the challenges facing telco operators:

  • Network complexity due to multivendor, best-of-breed environments that lead to long service provisioning cycles, particularly as operators begin to decompose those services into microservices;
  • Struggling to monetize use cases, even when there’s clearly market demand for the use case, because of lengthy service creation cycles and limited slicing capabilities;
  • High OpEx because of multiple O&M stacks from different vendors to manage the core, the edge, and the cloud;
  • Lack of service velocity as operators continue to rely on inefficient processes that do not support the need for continuous delivery, testing, and integration (CI/CD/CT);
  • Too many different workflows that strain an operator’s support capabilities;
  • Keeping up with evolving 5G and MEC standards from 3GPP, ETSI, TM Forum, and other groups.

So, what do operators need overcome these challenges and achieve true digital transformation? An orchestration, automation, and management platform that is designed from the ground up to support this kind of transformation. This platform would need to rapidly migrate legacy technology. It would need to accelerate new service creation by leveraging pre-defined service templates. It would have to operate seamlessly across any cloud environment. And, perhaps most importantly, it must reduce or eliminate the amount of coding needed to complete change requests and other historically resource-intensive tasks.

Where can operators find a platform like that? With Affirmed’s UnityCloud Ops.

Introducing UnityCloud Ops: Orchestration for 5G and the Cloud

Affirmed’s recently introduced UnityCloud Ops is a completely new and cloud-native solution for telco cloud operations and management. Within UnityCloud Ops are tools, products, and technology that provide the service automation, simplified “any-G” network management, and network observability that telco operators need to digitally transform their business.

UnityCloud Ops addresses the challenges that telco operators are facing today as they look to embrace 5G and cloud technologies by:

  • Delivering intelligent automation through orchestration, network visibility, and big data/business intelligence;
  • Providing a common user experience across any cloud environment: private, public, or hybrid;
  • Supporting the leading network standards including 3GPP, SA5 O&M, and ETSI;
  • Adding dozens of pre-built applications that allow operators to rapidly address 5G monetization, MANO functions, and slice management;
  • Establishing the foundation for a DevOps approach to service creation that supports continuous integration, design, and testing (CI/CD/CT).

UnityCloud Ops delivers automation by implementing intelligent domain orchestration across service models, service templates, and workflows for each 5G use case. This automation features a no-code approach, instead using a GUI interface to create, orchestrate, and manage services. This approach has a number of benefits for telco operators: it eliminates the extra coding normally required for change requests and other tasks, it redirects skilled programmers to more critical tasks, and it drives down OpEx.

UnityCloud Ops offers robust slice management capabilities based on Affirmed’s unique technical approach to slice management, which addresses both the network slice management (NSM) and the network slice sub-net management function (NSSMF). Designed to interface seamlessly with third-party network functions, UnityCloud Ops simplifies and accelerates slice creation, slice monitoring, slice modification, and slice management using a standards-based approach.

Other key features of UnityCloud Ops include artifact management; lifecycle management across OpenStack, Kubernetes, and UnityCloud environments; northbound and southbound interface integration; real-time network observability through virtual probes; cloud management and optimization; and analytics/BI capabilities that support 5G’s network data analytics functions (DAF, NWDAF).

As you can see, UnityCloud Ops brings together a world of functionality to help operators simplify, accelerate, automate, and orchestrate their digital transformation in a soon-to-be 5G world. Stay tuned for more to come from Affirmed and Microsoft.

Microsoft and Affirmed: Accelerating the path to 5G Services in the Cloud

by Affirmed Affirmed No Comments

With the announcement of Azure for Operators, Microsoft has outlined a vision and strategy to unlock the power of 5G and bring cloud and edge closer than ever, opening new opportunities for service providers all over the world.

Microsoft’s recent acquisitions of Affirmed Networks and Metaswitch, while a surprise to some in the telecommunications industry, signaled  Microsoft’s long-term commitment to telecommunications industry. Telcom executives naturally had a lot of questions: What were Microsoft’s 5G plans? How would the new acquisitions align with Microsoft’s cloud strategies? Would Microsoft’s presence accelerate the arrival of 5G? Is Microsoft looking to compete or partner with telecommunications service providers?

Today, we can answer those questions.

On September 28, Microsoft for Telecommunications hosted its inaugural Telecommunications Executive Forum. This live event showcased Microsoft’s strategy, roadmap, and technology for 5G—some of it unveiled publicly for the first time. Attendees heard about Microsoft’s vision for 5G edge computing, cloud-based telecommunications, IoT, and a lot more. (Read more about Azure for Operators).

For Affirmed, it’s an exciting time to be a part of Microsoft. Our decision to join the Microsoft family was driven by the fact that both companies shared a unique vision for 5G and, together, could accelerate that vision. So far, the experience together has been overwhelmingly positive. Our customers are more excited about 5G than ever before, and our recent customer successes validate the vision that Microsoft and Affirmed share for the future.

Since the beginning of the year, we’ve seen more and more telco operators around the world not just testing 5G technologies but embracing them:

  • In Finland, home to the world’s highest consumers of mobile services, DNA is replacing their legacy mobile core with a 5G core to serve up high-speed, high-bandwidth connections and meet consumers’ ever-expanding appetite for mobile services.
  • In Latin America, Millicom is moving to a cloud-based, 5G-ready mobile core to roll out new edge-based services to their customers such as augmented/virtual reality experiences and IoT applications.
  • In the Middle East, Asia, and Africa, Etisalat is leveraging next-generation network automation and orchestration as they continue to roll out 5G and multi-access edge computing (MEC) services.
  • In Sweden, Netmore is adopting 5G technologies to gain an early market lead on private enterprise services and IoT applications across Europe.

Bringing together the industry’s first cloud-native mobile platform and the world’s second-largest public cloud network provides telco operators with a clear, proven, accelerated path to 5G services in the cloud. Microsoft’s announcement to build a comprehensive cloud platform for 5G service providers is a game-changer for telcos. As for Affirmed, being a part of Microsoft expands the kinds of solutions we can offer our customers, including the option to consume a cloud-based mobile core platform as a service on world’s most advanced cloud computing platform.

A merger is often compared to a marriage. After the initial honeymoon, the real test of the relationship begins as you discover how well you work together. What we’ve discovered is that all the things that attracted us to Microsoft are the same things that make us stronger together. We’re both one hundred percent committed to the cloud as the next-generation platform for telecommunications. The unmatched flexibility the cloud platform offers—from on-prem deployments to mobile core as a service—enables operators to evolve at their own pace.  We both believe edge computing is integral to the success of 5G. We believe in open standards that invite innovation. We both believe in partnering, not competing, with service providers. And, most importantly, we share the same goals and dreams for the future.

In the days and months that follow, you’ll see that future unfolding. You will see how Microsoft, Affirmed, and Metaswitch teams are working together on a diversity of offerings. Microsoft’s Azure platform is a critical piece of the telecommunications industry’s future, and we’re proud to be an important part of that. For Affirmed, it’s been a long and interesting journey from a start-up with a vision of a cloud-native mobile core to being an instrumental part of Microsoft’s vision for the future of telecommunications.

The best is yet to come. We can’t wait to get started.
