Exclusive interview with Kobus Smit, Head of Voice and Messaging, Deutsche Telekom

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.

After a long wait mobile operators worldwide are testing and launching the long expected VoLTE services in their high-speeds LTE data networks now the VoLTE enabled smart phones spread the market in big numbers. With this, customers are finally offered a carrier grade voice app that offers the same comfort and trust to which they have become accustomed to with circuit-switched mobile voice services.

Maria Cuevas, Head of Core Mobile Networks Research, BT is taking part in a panel discussion on Day Two of the 2nd annual LTE Voice Summit, taking place on October 7th-8th 2014 at the Royal Garden Hotel, London.

In this interview she presents some of her personal views on VoLTE – please note, these do not reflect the official views of BT.

As we approach commercial launch of VoLTE services in the IUK is there any clearer idea of whether VoLTE will truly compete or just complement OTT services? 

My personal view is that VoLTE will be positioned and seen by the customers as an enhanced primary voice service and therefore will continue to be the main choice for of reliable voice communications for customers, complemented by OTT voice for certain scenarios. (more…)

SKT in good voice as it shows operators the way to go

SKtAt the second day of yesterday’s LTE Voice conference, which took place in London, the presentation by Changsoon Choi of SK Telecom attracted a positive responses from the audience, and really brought home how ahead of the game the South Koreans are in LTE and with particular relevance to the conference, in terms of VoLTE.

Choi started with a simple list of SKT’s achievements in LTE so far. As of 2012 it had 99 per cent population coverage based on a dual layer 850MHz and 1800MHz multi-band network and currently has 89 cities running dual-carrier LTE Advanced, all of which means it’s no surprise is enjoys 48 per cent market share for LTE in the country.

Interview: Director of RAN development & programmes, EE, UK: “We believe that ensuring excellent quality in mobility will be the biggest challenge.”

Mansoor Hanif, Director of RAN development & programmes, EE, UK is speaking in a panel discussion on the evolution of voice services on Day One of the inaugural LTE Voice Summit, taking place on October 1st-2nd at the Hilton Paddington, London. Ahead of the conference we find out more about the recent advances EE has made to its network and find out more about the challenges that implementing VoLTE will bring.

EE has recently moved to offer ‘double speed’. Can you explain technically exactly what you did and what the challenges were?

From launch until June of this year our 4G network was running on 2x10MHz of 1800MHz spectrum. Technically this allows a maximum speed of around 70Mbps per second. Since June we’ve doubled the spectrum used for 4G to 2x20MHz, increasing the maximum theoretical download speed to 150Mbps in 20 of the largest cities across the country. The maximum upload speed was also increased to around 45Mbps. In real-world usage, this translates to average user download speeds of 24-30Mbps, and upload speeds often in excess of 20Mbps.

Jason Penton, senior manager for applications and services for Smile Communications, South Africa is taking part is panel discussion on managing network traffic on Day Two of the inaugural LTE Voice Summit, taking place on October 1st-2nd at the Hilton Paddington, London.

What are the biggest challenges to implementing VoLTE on your network and when do you foresee it being rolled out?

The biggest challenge we face right now is the lack of availability of true VoLTE devices. When we refer to a true VoLTE device, we mean a device that supports VoLTE natively, not through an over-the-top (OTT), add-on application. We have already tested VoLTE on our network using OTT IMS applications on an LTE access device but this to us does not represent a true VoLTE device. We will be ready to launch VoLTE services on our network as soon as true VoLTE devices become readily available.

Franz Seiser, VP Core Network and Services, Deutsche Telekom, Germany, is speaking on Day One of the LTE Voice Summit, taking place on October 1st-2nd at the Hilton Paddington, London. Ahead of the show we speak to him why operators have been slow to implement IMS and the benefits the services running on it will bring.

At the LTE Voice conference you’re addressing the issue of slow IMS deployment. Do you think it’s symptomatic of the struggle that many telecoms operators are having moving to IP-based thinking?

The fact is that IMS deployments are rather slow. From a technology perspective this is due the extremely high complexity of these deployments. IMS complexity drivers can be split up into six different groups and IMS’ inherent complexities is one of these groups. The mismatch of traditional telco design approaches with IP technologies another one. I will give an overview on all six categories during my talk at the LTE Voice summit.

Michele Zarri, head of international standardisation and IP management, Deutsche Telekom, UK is speaking on Day One of inaugural LTE Voice Summit, taking place on October 1st-2nd at the Hilton Paddington, London. Ahead of the show we speak we get an update on Deutsche Telekom’s progress on VoLTE.

When we spoke in May you said that consumers will use VoLTE as they prefer telco quality voice services? With OTT voice set to grow massively over the next 12 months will consumers really care about VoLTE?

I respectfully disagree with the notion that OTT voice is set for a major growth. Though LTE will greatly improve bandwidth and latency, current HSPA and WLAN access is perfectly capable of supporting OTT voice. As smartphone penetration for which many OTT voice clients exist is already significant, there therefore seems to be not much reason why customers should suddenly change their habits. OTT will grow because the general trend of voice traffic is growing, but I still see OTT voice as a different product than VoLTE and catering for different use cases.
