The Mobile Network Operator’s Cry for LTE Services is Answered by APEX Communications’ Visual IVR.

This guest post was written by Elhum Vahdat, Executive Vice President, APEX Communications

Services, Services, Services…  you can practically hear the cry of Mobile Network Operators (MNOs) all over the world pleading for new (or even old) services that can run on their shiny new LTE networks.  Of course, this is nothing new, as this repeated cry for services is generated with the roll-out of every new generation of network (e.g. 2G, 3G), because MNOs are well aware that the serious payoff comes primarily from running  new services, which in turn can justify their investment.

Keep in mind, in this blog I won’t address what over-the-top (OTT) services are doing to the bottom line of MNOs, which goes without saying is why new services offered by the MNOs are so critical.

One service that is ideal for LTE is Visual Interactive Voice Response, or Visual IVR (different than Video IVR).  At this point I know what a lot of you are thinking…  IVR is dead, so why resuscitate it for a new network?  My short answer is that Visual IVR is not your parent’s IVR.

Your Data is talking – It’s Time to Listen and Engage!

Guest blog written by Oded Sela, Technical Director EMEA, International Sales at Allot Communications

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 – How to better monetize LTE Roaming

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.

5 Ways IPX is making LTE a global success

This guest blog was written by Jay Jayasimha, Chief Technology Innovation Officer, Cataleya 

Jay Jaysimha

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.

PCRF: A Vital Component in the Service Provider’s Network

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

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.

Exclusive interview – Steven K. Berry, President and CEO of CCA (Competitve Carriers Association)

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.

The Fine Art of Protecting Subscribers Including Our Kids – Network-based Solutions Anyone?

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.

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.

Exclusive Interview – Twitter and OTT partnerships with mobile operators

Arvinder Gujral, Director Business Development APAC, Twitter

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 – www.lteconference.com/asia

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.

Over-the-top (OTT) content and service providers that monetise traditional service providers’ infrastructure — fixed and mobile infrastructure in which these operators have invested heavily — are shaking things up in an already competitive market.

OTTs are using software-defined networking and virtualisation to reap the benefits of the infrastructure and access networks of bigger players — with great success. The new forces in play are gaining a lot more awareness from traditional service providers.

The Red Pill…

“You take the blue pill, the story ends. You wake up in your bed and believe whatever you want to believe. You take the red pill, you stay in wonderland, and I show you how deep the rabbit hole goes.” Morpheus, The Matrix (1999).

Red pill blue pillExperiencing the soothing hum of routers, switches and servers at the NOC, one imagines the green flashing lights assuring us all is well with the world ‘out there’ – the core, backhaul and RAN fully operational….keeping us calm and centered in our work. We know our job is done and we admonish any unbelievers with a stern, confident voice. When the customer support team calls in a panic because they have been flooded with customer complaints telling us the network isn’t working in the city, we smile and let them know they can stop worrying now, the NOC is fully operational and all systems are go. Then we sigh and hang up the phone on them when their tone of voice becomes, well, less than professional.

Yes indeed, all is well down here at the NOC, although, worryingly, even though I’ve full signal strength on my own phone, I can’t seem to connect properly to that Lync conference call because it keeps stuttering and dropping out. The director will be upset, but it’s ok- I’ll just say I just had network problems…

Is there a glitch in the matrix?

Are telco operators stuck in the “Blue Pill” world of The Matrix – the veil created by comfortable green lights and dashboards? On the surface the answer is “no”: Network monitoring and assurance tools are more sophisticated, incorporating big data, analytics and visualisation, providing richer and better information about the going-ons in the network. But what’s happening outside, in the reality of the customer? How do customers experience our network?

Operators should know; research demonstrates network customer experience to be the number one driver of both retention and churn. Customers want their applications to just work and they don’t care what’s happening deep in the NOC – and nor should they. If customers can’t use Spotify on their phone, then for them the network is broken and they will leave it in search of a better one.

What is a “Red Pill”? The view of the Wonderland of the customer:

  • A 100% customer-side view of the Customer Experience (CX) of applications and services on their phone.
  • A geographic view, in real-time and without long feedback cycles.
  • Correlating the customer experience to the state of the network
  • Benchmarking CX against the competition

By taking the “Red Pill”, operators can do some serious Bullet-Dodging. They’d be able to;

  • Conduct evidence-based network optimisation and investment decisions – the “outside in” network customer experience data can be used to guide network optimisation decisions or as supporting evidence for localised investments
  • Accelerate mean-time-to repair – by linking the customer experience perspective with their own network management capabilities, operations and assurance departments can isolate and correct network faults much more rapidly
  • Target local acquisition campaigns in those geographies where their own network is performing comparatively stronger than others

Operators who take the “Red Pill” see how deep the rabbit hole of network customer experience goes, understand the reality of the customer’s world and in the process gain significant competitive advantage.

Bringing Accurate Synchronization to Small Cell Backhaul

This guest post was written by Alon Geva,Timing & Synchronization Expert, CTO Office, RAD Member of the ITU-T SG15/Q13 Sync Standardization Group

This guest post was written by Alon Geva,Timing & Synchronization Expert, CTO Office, RAD & Member of the ITU-T SG15/Q13 Sync Standardization Group

Delivering sub-microsecond time accuracy to the cellular base stations is one of the major challenges facing cellular providers as they deploy their new LTE networks. This is exacerbated by LTE-A’s stringent synchronization requirements and the growing use of small cells in 4G networks, which create unique challenges in the backhaul segment.

Before the debut of 4G, the standard way to deliver a time reference was to install a Global Navigation Satellite System, or GNSS (e.g., GPS) at every cell site. A GNSS receiver is usually referred to as a Primary Reference Time Clock (PRTC). This approach is impractical in 4G, however, given the far greater number of cell sites, the intended indoor location of part of the antennas (e.g. shopping malls), as well as the growing concern about possible jamming and spoofing. Furthermore, considerations of CapEx and OpEx render this approach highly ineffective.

Professional testing is key in ensuring high QoE for VoLTE

This guest blog post was written by Kai Ojala, CTO, Anite Network Testing

The requirement for VoLTE is to offer high-quality voice calls and video calls, which as a baseline requires wide LTE coverage. LTE networks fulfill this aspect – especially lower carrier frequencies are deployed globally (e.g. 700 and 800 MHz frequency bands). Operators will benefit from customers switching to VoLTE services by harmonizing voice services and getting better capacity out of the spectrum.
Voice calls in LTE networks can be handled using Circuit Switched Fallback (CSFB) and Voice over LTE (VoLTE). CSFB provides a mechanism to transfer an initiated voice call to legacy circuit-switched networks. VoLTE, on the other hand, is a fully packet switched technology which uses Voice over IP (VoIP) technologies. With the SR-VCC functionality voice calls made with VoLTE can be switched over to legacy networks when the user moves out of the LTE network coverage.

What is Unknown RF Antenna position costing your company?

This guest post was written by John Vetter, VP of Business Development, Sunsight

Directional RF antenna installations are not always dantennaone to carrier RF design specifications for azimuth, mechanical tilt and roll.  Some before/after audits have shown that as many as 40% of antennas are installed more than five degrees off target.  Using this audit data, simulations are possible with RF network propagation software and any market final design project.  These results will prove that even when using conservative misalignment changes that induced network interference can be costly to carriers specifically for newer interference prone LTE technologies.  Focusing just on carrier spectrum capital investment this number can easily become surprisingly high when considering large nationwide RF spectrum investments.   The cost of ‘wasted’ spectrum due to interference does not, but could consider additional costs of ‘unused’ BTS/RAN infrastructure, unnecessary network performance troubleshooting efforts, less the credible output from RF propagation, ACP and SON tools , and more important, the effects of poor customer data experiences  -all caused by misaligned RF antennas.

The pocket sized Bolt! streams 4G to smartphones, tablets or laptops – making high speed LTE accessible on the move.

The emerging markets of Asia (EMAP) could soon be the most important LTE markets in the World.

All eyes are on the emerging markets of Asia Pacific; countries including Bangladesh, China, India, Indonesia, Malaysia, Pakistan, Thailand and Vietnam among others, as they begin to deploy and expand their LTE networks.

Studies show that EMAP is set to outstrip the developing markets of Asia Pacific (Hong Kong, Singapore, Japan, Taiwan, South Korea and Australia) in terms of LTE subscribers by 2017, creating a tremendous opportunity for LTE players across the region. As demand grows, users will require connectivity throughout the region, meaning more complex networks, better service and competitive rates across the board. (more…)

This post was written by Dr. Femi Adeyemi, LTE Solutions Architect at Fujitsu Network Communications

 

Voice over LTE (VoLTE) is considered by many to be a revolutionary application, for both mobile operators and their subscribers:  Operators, once they establish VoLTE networks, will no longer have to maintain separate networks—circuit-switched for voice and packet-switched for data. As a result, they will see savings in both operational and capital expenses.  Subscribers who use VoLTE will be able to use high quality voice and data applications simultaneously, while enjoying greater clarity in voice calls.

However, VoLTE deployment has been slower than anticipated due to several challenges…
