New Service Provider Revenue Monetization Model
Just as LTE has evolved to be the predominant technology for mobile broadband providers -- generating an average data volume per user of 168% higher than 3G data – so must the traditional charging model change. One charging model growing in popularity is Sponsored Data Charging.
Sponsored Data Charging enables mobile subscribers to view, stream, and benefit from sponsored content and use applications over the mobile service provider’s network without that data usage coming out of their monthly plan. The data charges that a subscriber would pay for the sponsored content are paid instead by the third-party provider owning the content. Even more importantly, a subscriber can test out certain sponsored applications and features for a short time to determine whether to subscribe, without impacting monthly data-plan limits.
Not only is Sponsored Data Charging built for massive broadband usage from all kinds of connected devices, it also can support emerging technologies such as VoLTE and NFV. Key target industries include advertising, retail, media, entertainment, healthcare, and financial services.

VoLTE Challenges: The Case for Integrated Policy, Charging and Diameter Signaling
Hopefully, Voice over LTE (VoLTE) has arrived or is coming to your preferred mobile service provider. As mobile networks transform into end-to-end IP ones, the business case for VoLTE as a means for mobile operators to provide differentiated services, including high definition voice and multiple media ones, has become compelling and taken on a sense of urgency.
Indeed, it is being viewed strategically as a way for service providers to distinguish their services on the basis of Quality of Experience (QoE) from 3G and OTT voice apps. It is also seen as providing competitive advantage because of its ability to enable end users to seamlessly move from a voice call to a video call, or shift from one device to another in the midst of the conversation. It is why interest in accelerating VoLTE deployments is so high.
However, network transformations are not easy. VoLTE deployment and operations is an interesting case in point. It brings unique challenges for service providers related to policy control, charging and Diameter signaling control. Steffen Paulus, Director of Product Marketing, Alcatel-Lucent has some interesting insights worth sharing on the need for integrated policy, charging and Diameter signaling in a virtualized solution, as the path forward for VoLTE success. This is particularly relevant in light of Alcatel-Lucent’s recent launch of its End-to-End Voice over LTE (E2E VoLTE) solution that is an integral part of the Rapport multimedia real-time communications platform which has been architected specifically to me service provider and enterprise needs.

As they move into the cloud era, network operators need a service aware network operations tool to assure virtual network functions (VNF) management. They’ll need it to efficiently perform a variety of network operations tasks, including:
- Service impact assessment
- Fault localization
- Identification of true root-cause (from symptomatic faults)
- Taking corrective actions to resolve problems fast
As described in a vEPC post related to converging NMS and VNF manager functions within the ETSI Management and Orchestration (MANO) architecture, operators need to evolve their network operations tools for NFV through tighter coupling the NMS and VNF manager functions. Specifically for VNF assurance, the blog states “Troubleshooting is simplified because traditional NMS faults/events are correlated with VNF related events/faults. The VNFM provides lifecycle management and automates the self-healing of VNFs.”
Rarely does a video about network functions virtualization (NFV) captivate your attention like the one that Alcatel-Lucent recently uploaded about service innovation and lean operations in the context of NFV. Sometimes NFV can be a challenging concept to get your head around, but the video breaks it down with clear visuals and none of the PowerPoint that usually puts you to sleep.
If you haven’t seen the video you can watch the embedded version below. But also let me explain what the video is talking about.

Can the virtualized evolved packet core (vEPC) be deployed today in large scale, LTE networks? Mobile network operators (MNOs) are increasingly convinced that the vEPC has become viable both financially and technically. And I think so, too, based upon the advances made over the past year that I’ll discuss in this blog.
OpenStack isn’t an as-is solution for telco network functions virtualization (NFV) infrastructures. OpenStack is an open-source cloud management technology that provides many of the capabilities needed in any NFV environment. And this has prompted interest among many telco service providers.
But to realize the full benefits of NFV, service providers need NFV platforms that provide additional capabilities to support distributed clouds, enhanced network control, lifecycle management, and high performance data planes.

This article discusses the progress in the development and operational management of the vEPC to support the LTE consumer network. It answers the question: Is the vEPC commercially viable in large-scale, LTE network deployments? At Mobile World Congress 2015, Alcatel-Lucent will show a live demonstration of vEPC dynamic scaling together with simplified NFV management and orchestration.
Over the past several years, I’ve met with many mobile network operators (MNOs) and discussed their plans for virtualizing the evolved packet core (EPC). It’s clear from the more recent conversations that MNOs are now convinced that the vEPC is both financially and technically viable for their networks. But is the vEPC ready for the MNO’s LTE consumer network? In this article, I’ll discuss why I now think that’s possible.

There’s no question that the network functions virtualization (NFV) technology around which many telecommunications carriers and vendors are rallying takes a page from the virtualization that already has taken hold in IT data centers. But you can’t judge a book by its cover. NFV and IT virtualization also have their differences.
One key difference is that while data center virtualization tends to rely on a centralized architecture, NFV calls for a distributed one, Andreas Lemke, marketing lead for the CloudBand NFV platform at Alcatel-Lucent, points out in a recent TechZine posting by Andreas Lemke, Marketing Lead, CloudBand NFV platform, Alcatel-Lucent titled, Why distribution is important in NFV.
One of the things that will characterize 2015 is the trend that started picking up momentum in 2014 that operators of physical communications networks have developed a sense of urgency about transforming their networks. It used to be that if you were a network operator you could invest with some level of assurance that the hardware and the associated software to run it would be core to your network for possible decades before becoming obsolete. However, as everyone in the industry knows, this is no longer the case.
As the world becomes more software-centric in terms of service creation, delivery, agility, security and performance— to meet the tsunami of data heading operator’s way and to allow network operators to maintain their relevance as ecosystem hubs rather than “dumb pipe” providers—cost efficient and effective operational excellence and the need to be fast-to-market and fast in the market with innovative services and enhanced customer experiences have become paramount. It is why so much attention is being paid to thing like Software-Defined Networks (SDN) and Network Functions Virtualization (VFV).
The need for speed has become (pardon the turn of phrase) hyper-critical. However, with recognition of the need to transform and do so rapidly should also come the recognition that network operators cannot transform rapidly and successfully on their own...

Service providers are undergoing a sea change.
Their networks, which traditionally have been based on turnkey network elements running software on purpose-built hardware, are moving to a software-centric model. In this model the true value lies in the software, while the hardware is typically of the commercial-off-the-shelf variety.
Network Functions Virtualization (NFV) is the name of this new architecture, which not only embraces the model of instituting network functionality in software and running it on industry-servers, but also allows applications and services to leverage those resources whenever and wherever they are.

It feels like it was just a few months ago when you could read articles in the trade press lumping together SDN and NFV with NFV being a form of SDN or vice versa. Yes, both somehow are about virtualization and about converting hardware into software. Today – after numerous proofs-of-concept run by service provides around the globe – we know the role of SDN as virtually indispensable for NFV solutions that aspire to deliver the kind of agility and operational simplification we all expect from NFV. Only SDN can deliver quickly enough the (virtual) networks needed for newly deployed network functions. Alcatel-Lucent has recently demonstrated a complete virtual evolved packet core (vEPC) including a virtual IMS/VoLTE deployed in less than 30 minutes.
The advantages to mobile operators of network functions virtualization (NFV) and moving to a virtualized evolved packet core (vEPC) have become clear, and mobile networks operators are pretty much sold on the technology in theory.
As the technology side has been figured out and operators begin to plan commercial deployments of NFV and vEPC, however, discussion is starting to move toward operational requirements and challenges. Mobile network operators need to figure out how best to manage these new virtual network functions (VNFs) and the NFV infrastructure, and also how to modify the existing network operations model when these VNFs are deployed.

Open source has had a massive impact on information technology and the web: The Linux operating system, the LAMP stack, browsers, the Android smartphone OS. Individual enthusiasts, universities, and businesses spend enormous resources to build technologies, and then give them away for free. Are they out of their mind? The success of open source shows they are not.
OpenStack, the open source cloud management software, has come into the focus of service providers as a rapidly advancing, cost-effective technology foundation for NFV. With OpenStack, service providers are expecting to escape the tangles of individual vendors and build an open horizontal platform for their future networks.
Large enterprises increasingly resemble public network service providers as they manage access, transport and network routing while controlling devices and sessions. Whether businesses build their own or buy their communications services through a public provider, the IP communications architectures are looking remarkably similar.
“I’ve noticed that both private service operators (CIOs of large enterprises) and public service providers are implementing very similar solutions around the globe,” wrote Oliver Krahn in a recent TechZine article, 6 Steps that Improve Communications Services.

“GM factories reduce production in aftermath of Japan earthquake 2011”, “Hard disk shortage due to Thailand flooding 2012“, “Drug shortages continue to vex doctors”, “China factory fire sends memory chip prices to three-year high (2013)”. Industrial supply chains are becoming increasingly tenuous as they are thinned out and stretched across the globe. Raw materials are available from fewer and fewer specialized suppliers and warehouses are eliminated for just-in-time production. Small, local incidents affect the supply of goods on a global scale.
In the IT industry we are seeing a similar trend. Enterprises are moving their applications and data to the cloud, but this cloud is often highly centralized and not as resilient, free flowing, or efficient as one might think. Amazon Web Services, the largest cloud provider in the world, is serving their global customers from no more than two handfuls of locations. Netflix and other companies have experienced major outages due to single failures in the cloud they used.
So what does this mean for NFV?
We live in exciting times – again. I had been wondering if there was still room for fundamental innovation, for technological disruption – the worn out word. We had the Internet bubble that burst 2001/2002. We had the advent of the smartphone in the recent years. Great innovation, but somehow they reached a plateau. Faster processors, larger screens? It doesn’t seem to make a real difference. Apple’s engine showed the first signs of sputtering.
And yet, there is something brewing behind the scenes that makes the engineer’s heart beat faster: NFV and SDN, a bold new vision about the future of networks (read these blog posts about understanding Network Functions Virtualization and Software Defined Networks). Network functions are to be reduced to pure software - doing away with all the special purpose chips, circuit boards, and cabinets into which we have poured our brains to deliver the ultimate in features, performance, and reliability.

While network functions virtualization (NFV) introduces new challenges to security, it also presents unique opportunities for addressing security problems due to the unprecedented scale, flexibility, and central control it affords. Compute, storage, and network resources can be optimally allocated and stitched together as required by the security policy. Our approach to address NFV security is based on a recursive, divide-and-conquer methodology, which involves securing the Alcatel-Lucent CloudBand™ NFV Platform, cloud nodes, and the network that interconnects them. CloudBand uses policy-based placement capabilities enabled by the CloudBand Management System to install virtualized functions in their appropriate security zones, and re-uses the security services provided by NFV applications.
I thought it would be a good idea to describe the journey to this approach together with its "making of" episodes.

As you already know, the cloud is one of the megatrends of our times, and service providers are embracing the open cloud with the help of network functions virtualization (NFV).
An NFV platform enables providers to run network functions on a homogeneous, distributed cloud infrastructure. Using an NFV solution, they can port network functions such as communications and messaging applications and fixed and mobile network functions over to a virtual machine environment. Freed from proprietary, physical hardware, providers can leverage this virtualized infrastructure as the basis for their own service platforms and operations.
Seeing the opportunity inherent in NFV, as described in detail in an applications note Alcatel-Lucent has developed a purpose-built NFV platform for service providers, CloudBand. The platform supports distributed clouds and dynamic network control to meet application demands, and it optimizes network operations by automating cloud node management, application lifecycle management, smart placement and network configuration.
