CSPs are under constant pressure to be proactive all the time, since they need to stay ahead of the competition and are facing challenges on a daily base. But first and foremost, they need to keep their subscribers happy – not an easy task!

What is the secret sauce that they can use for success? Simple: they must analyse and optimise!  Why is analysing so important? Analytics will help operators to find the right optimisation for improving the QoE (Quality of Experience) of their subscribers. It also enables creating and activating optimal use cases, which boosts the bottom line. Furthermore, it allows a CSP to stand out in the crowd, increasing its ARPU and revenues!

Guest post written by Michael Van Veen, Global Sales Director for IPX services at SAP Mobile Services

For those of us who are walking around with LTE devices and have experienced high-speed data services, there is no going back: we feel the need for speed.  And naturally, wherever we travel we expect to get the same service performance that we experience in our home network.  We will suffer low-speed 3G connectivity if we have to, but only to get to our email or to chat with friends.  If we cannot get access to LTE for heavy-duty things like content-rich social media services, we will start looking for WiFi connectivity.

Mobile operators have always worked hard to follow their subscribers wherever they travel.  Roaming agreements make sure that their subscribers can use their device on visited networks: they can make and receive phone calls and SMS, and use data services.  The operators can even “steer” roamers to networks which are guaranteed to deliver the most commercial or technical benefits.  Now that we have entered the era of LTE, all of these efforts need to be repeated.

Operators worldwide have either recently exhausted their LTE network CAPEX or are squarely at the center of it. VoLTE announcements are only accelerating the momentum while providing proof that the tide of advanced IP service adoption is changing. The thing all operators have in common, however, is that they face market pressures for VoWiFiVoLTERCS, and other advanced IP services—many of which have IMS requirements for basic functionality or optimal performance. Thus, when additional changes to the network core are needed to facilitate IP service launch, the cost and complexity of the endeavour through traditional deployment methods can be too lengthy for most operators to meet current demand. For these reasons, virtualisation must be explored.

A virtualised IMS core allows for the quick deployment of cloud-based advanced IP voice and messaging services. WiFi calling is the most crucial service requiring immediate deployment to solve operational issues like in-building coverage and consumer demand. Additionally, the seamless layering of future services that grow with and meet demand is an advantageous way for operators to stay competitive in their market.

LTE needs IPX to be a truly global success. When domestic LTE deployments are supported by global IPX-enabled networks, it changes what is possible in the mobile market. Today, we’ve seen the development of LTE networks on a local level but for 4G services to mature and realise their full potential LTE needs to be supported with robust, reliable and intelligent IPX-enabled networks.

There will be 450 commercial LTE networks deployed by the end of 2015, according to The Global Mobile Suppliers Association (GSA). Close to 50% of subscribers in Q4 2014 were in Asia-Pacific with North America and Europe trailing close behind.

Guest blog written by Udayabhanu Parida, Product Manager, Simulators, Wireless Division, EXFO

With the wireless industry moving toward a unified IP network carrying both voice and data traffic, policy and charging rules function (PCRF) will be taking on an increasingly important role in managing the service provider’s network resources and monetization of service usage. And, with the planned adoption of Voice over LTE (VoLTE), PCRF will be playing an increasingly vital role in the network.

A key component of building a fast and reliable wireless network includes extensive testing of the network elements (NEs), in this case PCRF in the test labs before deployment. In test labs, PCRF is normally tested with other real NEs, such as PDN GW. Such a test setup does not fully exercise the functionality, performance or capacity of PCRF, because PCRF not only communicates with single PDN GW, but multiple PDN GWs. PCRF also communicates with policy control enforcement function (PCEF), such as deep-packet-inspection (DPI), online-charging-system (OCS), and offline-charging-system (OFCS) functions, as well as other PCRFs (visited), call session control function (CSCF), serving gateway (SGW), gateway GPRS support node (GGSN), traffic detection function (TDF) and more.

Steven K Berry, President & CEO of CCA

Steven K Berry, President & CEO of CCA

Ahead of the 8th Annual LTE North America event in Dallas, TX this November 18th & 19th, we had the opportunity to interview Steven K. Berry, President & CEO of the Competitive Carriers Association (CCA).

In the interview Steven shares his thoughts on the key challenges being faced by competitive carriers throughout the U.S., the industry’s concerns looking forward to 2015, and the path towards a competitive landscape for all carriers.

Q. What are the key challenges faced by North American carriers today in the roll-out and upgrade of LTE networks?

A. Competitive carriers must have access to critical inputs including access to spectrum, access to the latest, most-advanced handsets, and reasonable roaming agreements to continue to improve and build out their networks.  Carriers in the most rural and hard to serve areas also need certainty regarding sufficient Universal Service Fund (USF) support.  Competitive Carriers Association (CCA) works each and every day to ensure our members, nearly every wireless carrier in the U.S. outside of AT&T and Verizon, have the opportunity to grow and thrive, and to do so, they must have access to these inputs to find a pathway toward the next generation of networks.  The wireless industry is, unfortunately, plagued by continued consolidation – a significant challenge for smaller carriers trying to compete with the two largest national carriers.  We have been working closely with the Federal Communications Commission (FCC or Commission), Congress and the Administration to ensure policies are in place that will allow our members to enhance their networks and serve their customers the best way possible.  Tim Donovan, VP of Legislative Affairs for CCA, is speaking at the LTE North America event and will address some of the critical policy issues for CCA members and how decisions made in Congress and at the FCC affect not only the carriers, but consumers and the economy as well.

Source: Verizon will test insanely fast new wireless technology

Benjamin Franklin said there were only two things certain in life: death and taxes. Well, I would like to add a third one: online threats.

Operators are facing the daunting task of keeping their subscribers (and their own networks!) safe from a slew of cyber threats that are getting more and more complex. Fraudsters use a combination of backdoor methods, engaging unwitting cooperation from innocent, targeted users.

TL;DR: NFV Promises To Alter The Value Proposition For Network Operators Of All Sizes

As we prepare for SDN Asia 2015 in Singapore this October, we look forward to discussing how executive telecom decision makers want to capitalize on the APAC market’s propensity for rapid technology adoption by providing an abundance of services at the lowest costs. NFV enables rapid service creation while lowering costs, but it is necessary to not sacrifice performance in the process.

Performance continues to drive the NFV discussion because without proper oversight, virtual machines and cloud infrastructure can be real headaches by demanding increasing requirements of hardware to accommodate an increasing software footprint. To achieve an abundance of services at the lowest costs, enabling performance in the initial design architecture will help further drive the costs down. There are two major areas of performance bottlenecks that organizations should evaluate to enable the full promise of NFV.

Guest post written by Paul Gowans, Mobility Marketing Manager at Viavi

VoLTE has evolved significantly from a year ago. At the event last year many operators were planning their VoLTE roll-out and engaging their technology partners such as Viavi on the challenges to address and ensure they deliver on the high expectations of VoLTE. Now, we have many operators who have either deployed or are very close to deploying. Of course now that LTE is much more broadly rolled out, this sets the foundation for extra LTE-based services such as VoLTE.

There is also the area of the relevance of voice today – many people have an iPhone or other Smartphone and use a multitude of methods to communicate – certain generations don’t talk at all! So, the industry has had to appreciate that VoLTE needs to be integrated into the way people communicate today.

Arvinder Gujral, Director for Business Development APAC, Twitter

Our latest addition to the LTE Asia 2015 programme, keynote speaker Arvinder Gujral, Director for Business Development, APAC at Twitter will be joining us in Singapore next month to examine OTT/operator partnerships and how they are developing in Asia. I spoke to him ahead of his talk to get an insight into this evolving relationship;

“The biggest fundamental shift that has happened is that mobile operators have learned to evolve to the reality of Internet and Data superseding Voice and SMS, and have successfully adapted that to their business models and unit economics” he said “OTT providers on the other hand have also learned to work with the mobile operators, and at the same time added value to the operator’s core KPIs around Data and its new operating models. The apparent threat perception that was lingering for a while has been replaced with “lets-add-value” attitude to each other’s business, because at the end of the day it’s the end-user who needs to see benefit from both players, and not one over another.”

“The apparent threat perception… has been replaced with “lets-add-value” attitude”

“Twitter has always worked well with mobile operators; we have long-term relationships with over 500 operators globally. Over time our engagements have evolved from simple SMS connections and Twitter utilising an operator network, and more recently, with operators using the Twitter social graph and network to achieve their KPIs.

We tied up with 17 mobile operators globally for the FIFA World Cup last year, and five operators in South Asia alone for the this year’s Cricket World Cup. The aim was to take the best of Twitter for these events and make it available to the operators’ subscribers. The partnership worked beautifully as operators used their distribution and marketing effectively to show value of Data/Internet via a custom Twitter experience for these global sporting events. Of course, these successes are enabling us to evaluate bolder models to work with in the future.

Our recent partnership with Indosat (the first ever in APAC), where users of Indosat can now buy Voice, SMS, Data directly from Twitter, is another great example of how we are helping our operator partners add to their bottom line”.

But in this fast paced industry, where nothing ever stays the same – how will these partnerships evolve?

“As mobile operators look towards becoming digital operators in their own right, Twitter is in a great position to be ideal partners. We have announced Twitter Fabric, our suite of SDKs, that helps developers along the journey from idea to revenue. We have also started to work with mobile operators in their journey to explore this world of Mobile Apps and are sharing our insights, infrastructure and social graph to help them scale and eventually build additional revenue streams, all via our SDKs”.

“I believe LTE Asia will be a great hub where Twitter gets to learn from the mobile operators on what their concerns are and what they are doing about it. In that process, I can share my experience (in my previous career with a mobile operator) and partner with them through Twitter in their journey towards growing the digital mobile operator industry”.

Arvinder will be discussing Twitter’s operator partnerships during the LTE Asia Keynotes on the 7th of October. If you haven’t registered to attend the show yet or applied for a free operator pass, you can do so now buy visiting our website –

Haitham Mashal, Senior Director- CS Core, Du

Prior to the LTE Voice Summit (London, September 28th-30th), we interviewed Du’s senior core network Director Haitham Mashal about his views on the development of VoLTE, service planning and future opportunities. Here is what he had to say, ahead of his participation at this year’s summit.

Q. As we see the commercial launch, is there any clearer idea of whether VoLTE will truly live up to its promise?

A. No doubt VoLTE would even exceed its promise for both customers and Operators. Operators would have the chance to transform their networks into full fledge IP network and get the benefit of reducing both CAPEX and Opex. Operators would also be capable to offer better Voice quality with enriched services on top of the voice that can compete with OTT voice services.

Customers would enjoy the enriched crystal clear HD voice and shorter time setup. This would definitely enhance the customer experience and satisfy the customer demands to enjoy different services simultaneously even during call establishment.

If someone were to define a safe bet, it would be on the number of blogs about NFV, its drivers and benefits out there, by far exceeding the actual number of Virtual Network Functions deployed. So please let me try a different perspective.

We have been talking about NFV for more than two years now. There is no shortage of studies and surveys on its drivers and potential, but what can be said about reality? A reality I would like to delineate as follows… To CTOs and CIOs, NFV (and SDN) is something to drool or to brag about: “We will adopt it” or “We have great results from adopting it”, and an occasional “We have been doing it in the lab for ages, so…?” . But as Geoffrey Moore tells us the “Techies” and “Visionaries” don’t make a technology, until it can be recognised by the majority.

Here comes the important part for “crossing the chasm”: How about successfully addressing the key CFO’s question, “Show me the money”?

What makes me feel great about NFV now becoming a reality, is the fact that there are numerous examples globally, where CFO’s have “found the money”, resulting in commercial NFV deployments. Take AT&T Connected Cars or Telefonica’s “LTE in a Box” as an example for revenue increase business case – not just an approved one, but a proven one! How about a cost reduction one like XL Axiata are confidently aiming for . And if you think increased agility is an esoteric one, look at what Aspider or NAKA Mobile can create with NFV, agility does get signed off, so I assume it also pays off!

In the whole discussion, using Geoffrey A. Moore’ “Crossing the Chasm” reference, is it important where to place the named service providers? Maybe as pragmatics – but what is far more important than a classification is the fact that they are doing it – congratulations!

I do acknowledge that there are still many challenges ahead to reach mainstream Mobile NFV deployments– orchestration or  interoperability being one of them (thank you Light Reading and EANTC!), and I am as pleased as I am sure to believe they would be adequately addressed. But that’s maybe another blog some time soon.

This guest post was written by Alon Geva, Timing & Synchronization Expert, CTO Office at RAD

Delivering sub-microsecond time accuracy to cellular base stations is one of the major challenges facing cellular providers as they deploy their new LTE networks, creating unique challenges in the backhaul segment. This is exacerbated by LTE-A’s stringent synchronization requirements and, eventually, by 5G, now on the horizon.

Before the debut of 4G, the standard way to deliver a clock reference was to install Global Navigation Satellite System (GNSS) access at every cell site. A GNSS receiver is usually referred to as a Primary Reference Time Clock (PRTC).

The limitations of GNSS

This approach, however, is impractical in the 4G environment, since its network architecture is different. The most prominent change is that 4G accommodates large numbers of small cells to deliver higher capacities and data speeds. Stationing a GNSS antenna at every 4G cell site will be problematic due to cost. Apart from the unprecedented volume of antennas that would have to be bought, installed and maintained, the rapidly falling price of small cells will accelerate their deployment only further. Beyond all this, of course, is that every antenna requires an unobstructed sky view, a major problem for small cells, which, in many cases, are installed indoors, on building walls and closed spaces such as shopping malls, basements and traffic tunnels.

But that’s just the beginning.

The velocity in how the world creates value has hastened considerably. We spent millennia as an agrarian economy, then came the industrial age that refines these commodities into manufactured goods. We have since evolved into the service economy and most will agree that we are now onto the experiential economy.
To appreciate what that means to us in the telecommunications business, perhaps we can take a moment to follow the journey of the humble coffee beans.

Today, Mobile Service Providers find themselves struggling to cope with the increasing demand for capacity whilst maintaining a high level of customer experience. Trying to find the most flexible and cost-effective infrastructure to support next generation services whilst also attempting to reduce customer churn by providing adequate customer level Quality of Experience (QoE) & Quality of Service (QoS) can be difficult to achieve. Essentially, Service Providers are caught between a rock and a hard place.

Subscriber level QoE is a subjective matter that is a balancing act; there are a number of factors which need to be considered:

  • Localised low signal quality
  • Numbers of connections using the network in a particular area
  • The performance of a particular mobile handset
  • Download bitrate
  • Resolution and encoding of video content
  • Responsiveness of mobile or web based applications
  • User service plans

Ahead of the 3rd annual LTE Voice Summit 2015, I interviewed Kobus Smit, Head of Voice and Messaging at Deutsche Telekom who gave us an insight on services VoLTE will offer + customer benefits it will bring- here is what Kobus say’s  in this exclusive interview

Ahead of the 3rd annual LTE Voice Summit 2015, I interviewed Kobus Smit, Head of Voice and Messaging at Deutsche Telekom who gave us an insight on services VoLTE will offer + customer benefits it will bring

Q. As we see the commercial launch, is there any clearer idea of whether VoLTE will truly live up to its promise?

A. VoLTE offers some clear customer benefits – especially around HD voice quality and faster call set-up times, which we believe customers will notice and appreciate. There are also further advantages, like high speed browsing during a call, but the usecases are still pretty limited. The largest benefit of VoLTE, however, is arguably for the Operator and not so much for the customer as it facilitates the necessary transfer of voice to IP. We therefore belief that from a customer perspective “plain” VoLTE alone will not necessarily be a very convincing proposition.

Q. Can we expect to see new and innovative services built on top of plain audio VoLTE?

A. Yes indeed – and it is already being prepared. DT has developed an Enriched Calling proposition together with Sony, Vodafone and others, which we will be bringing to market soon. This enables customers to have a far richer calling experience by adding context and content before, during and after a call. The features include the setting of call importance, adding a subject, picture or location before the call; during a call, users can exchange, locations, draw on maps or pictures, share videos, images and files, and after the call customers have the possibility to leave a visual voicemail, a video or text message. All of this is delivered with very little incremental effort, by utilizing RCS functionality already available in the network and handsets to deliver a truly enhanced user experience.

Q. What is the future, beyond VoLTE? What are the next steps in network development?

A. We are deploying VoLTE on a local basis first and will then extend it to Roaming. We further plan to combine VoLTE with other voice services such as WiFi Calling and plan to establish Video Calling. With VoLTE as a basis for IP voice, it opens the possibility of further enhancement and service meshing in the IP domain.

Q. Network Function Virtualization for VoLTE- what does this to you and is the way forward for this service?

A. For us it is not about the virtualization of one single service, its more about the virtualization of the network infrastructure in order to be more efficient and offer better quality and service for our customers.

Q. What will be your key message at the LTE Voice Summit 2015?

A. Enriched Call builds an attractive proposition around VoLTE.

LTE adoption is exploding in Japan, Korea and other highly developed Asian countries; but in this “red ocean” competition is fierce – companies find themselves in a continuous arms race to deliver the most innovative solutions and keep their service offering one step ahead of the curve.

In the Emerging Markets of Asia (EMAP) development has, until now, been slower. But the opportunity for growth is huge.

Carrier Challenges

The sheer number of Wi-Fi connected devices is growing at a phenomenal rate, and Wi-Fi is fast becoming the preferred method of connection – at least two thirds of consumers today prefer connecting over Wi-Fi as opposed to cellular, mostly due to cost and performance.

Mobile operators have been increasingly turning to Wi-Fi offloading as a cost-effective way to manage data capacity, and that trend continues. Many analysts are forecasting a steady annual increase in carrier hotspots to more than 7 million by the end of 2015. (Source: ABI Research)

However, data offload is just the tip of the iceberg. The real reason many carriers are out there securing hotspot locations and launching services is competition for new revenue opportunities, from both incumbents and “over-the-top” (OTT) players alike.

Mobile operators have finally seen first deployments of this much talked about service and VoLTE is evolving as the platform of choice for voice calls + enabling additional services over the network.

VoLTE platforms are making significant progress in VoWiFi services too, with the aim of improved in-building coverage, however the quality of services is yet to be defined due to the complexity of the network.

As VoLTE is said to provide a long term solution for voice, does this mean 3G networks can be retired? What other benefits does VoLTE offer and how does this help operators retain profits, that were until quite recently lost to OTT players?

The 3rd Annual LTE Voice Summit, will address all current and pressing questions surrounding Voice over LTE along with bringing tier 1 operators + vendors sharing latest case studies from live VoLTE networks! Register + Join this flagship event today @

June is typically a very busy month, with a number of exhibitions to be attended. This year Eirteic attended TM Forum Live! in Nice and LTE World Summit in Amsterdam. The events created some interesting thoughts about how things are progressing around subjects such as: SDN, NFV, SON and 5G.

Mike Hooper, Head of Sales, Eirteic

Mike Hooper, Head of Sales, Eirteic

Given that we are 5 years since the first 4G rollout and 5 years from a 5G roll out, it got me thinking about how we are progressing with the management of LTE. The rollout is happening but how are we managing it? Service Providers are still using legacy platforms such as IBM Netcool and HP TeMIP.

So as we progress toward 5G, how is this going to really change? How do we manage legacy 2G, 3G services whilst maintaining LTE and assuring future 5G services.

Can we really do this using 20 year old platforms?
