Reston, VA – 25 November, 2015- Ascom Network Testing announced today it had won the award for Best LTE Core Network Product at the recently concluded LTE North America 2015 conference in Dallas, Texas. The company’s winning entry centered around TEMS™ Monitor Master, its offering for performing active testing and monitoring of any IMS-based service being deployed in the core network.
Finalists’ applications were reviewed by an exclusive panel of leading experts from Senza Fili Consulting, iGR Research, Signals Research Group and Wireless 20/20, and winners were unveiled during a ceremony hosted by Vicky Livingston, Head of Communications and Analyst Relations for 4G Americas.
Exclusive interview with Paul Gowans, Mobility Marketing Manager at Viavi
Paul Gowans, Mobility Marketing Manager at Viavi
Viavi Solutions (formerly JDSU, Arieso and Network Instruments) is very active in LTE and helping to advance the technology … how has LTE progressed since last year?
LTE as a standard continues to evolve to meet the growing capacity and coverage demands of mobile consumers. With LTE Advanced and LTE Broadcast being two examples. Yet it is the area of VoLTE which has probably seen the greatest change from last year. 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. There is also the area of the relevance of voice today – many people of course 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.
What are the top VoLTE challenges?
Working closely with our mobile operator customers and building on our experience with IP based voice services as well as RAN and Core network challenges I would say the top three challenges are:
- Voice Quality – measuring end-to-end (E2E) voice quality is fundamental to understanding the customers quality of experience (QoE). Knowing what metrics are important, where to measure and quickly finding the root cause of voice quality affecting issues.
- Handovers – when you move out of an LTE service area and have an active VoLTE call, the user will want to continue with that call. SRVCC seamlessly maintains calls when a mobile user moves from LTE to non-LTE coverage areas. Of course, there is the potential for things to go wrong and calls to get dropped. Also, if the user is not supporting VoLTE but is using LTE, when they receive a call the phone the network need to fall back (CSFB) so that both data and voice are non-LTE.
- Location – not only knowing what service is being provided to the consumer but also from where so that you can determine, for example, VoLTE hot spots – that is where there may be too many dropped calls or handovers have failed. By accurately geo-locating voice quality metrics you can make better business decisions on service delivery.
Presentation theme/message at the event?
In addition to introducing Viavi Solutions to the audience, Viavi will be presenting in 3 key areas, namely: VoLTE, HetNets and Network Optimization. The theme of the VoLTE presentation is how to address some of the key VoLTE challenges and ensure the subscribers gets an exceptional VoLTE service. We will be exploring voice quality- passive measuring, active measuring – how integrating handset data with core data and then geo-locate that information to maximize the business impact of the service. The E2E view of the service from device to RAN to backhaul and core. For HetNets we will be discussing workforce automation and how to ensure cell site turn up to be most cost-effective without impacting quality. Network Optimization will build on the extreme non-uniformity in cellular networks and how subscriber-based, location-aware predictive optimization is needed.
Meet Paul and the Viavi team at the upcoming LTE North America, in Dallas, next November 17th-19th!

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.
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.
