The World of VoLTE

In 2012, VoLTE made it’s debut with the first VoLTE networks being launched in South Korea. Not long thereafter, an increasing number of MNOs followed South Korea’s example by introducing voice on their own 4G networks. Since then, from 2015 to 2018, the number of VoLTE networks around the world has nearly tripled!

Expanding the Horizon of VoLTE

National and International Trade

Since the beginning of time people have been involved in trade, which involves the transfer of goods or services from one person to another. First locally, and later across borders. International trade of goods and services has taken place throughout history with classical examples such as the ‘Salt Road’, ‘Amber Road’, and ‘Silk Road’. In the Telecoms Industry, trading minutes is commonplace, especially across borders, where international communication has become an indispensable part of our everyday life.

Moving to VoLTE to the International Arena
As described by Adam Smith in his book “Wealth of Nations” merchants looked for an “absolute advantage” by learning to exploit their domestic strengths in the search of new economic opportunities. VoLTE, Voice over 4G, is as domestic strengths that Carriers are bringing from the national stage to the international voice market in order to find new opportunity in this highly competitive market. iBasis is proud to be a frontrunner, together with partner SK Telink, servicing the international VoLTE of MNO’s KPN Mobile and SK Telecom.

Today more than 100 domestic VoLTE Networks around the world are operational. A few of these are nationally interconnected, e.g. in South Korea, USA, Kuwait and China. Mobile operators in these countries provide their local subscribers with VoLTE’s high quality clear voice experience and fast data access across the domestic footprint. However, these national networks are like walled gardens with no actual connection to the broader world beyond the domestic borders, thus limiting the customer’s experience to their home market.

Milestone in VoLTE Interworking
Together with South Korean partner SK Telink, iBasis recently achieved a milestone in VoLTE interworking. As of May 2017 live VoLTE traffic began between mobile carriers, KPN in the Netherlands and SK Telecom in South Korea. The connection between these two domestic mobile carriers was facilitated by the IP networks of iBasis and SK Telink. The first international end-to-end VoLTE traffic! With a concerted, effort the KPN Mobile and SK Telecom subscribers are now able to call each other with a crystal-clear voice quality across boundaries, operators and borders.

With this breakthrough the march toward international VoLTE commercialization is also moving forward. High-quality voice service encourages usage on the mobile network, deterring users from seeking alternatives. Combined with global availability, they can become key competitive advantages for mobile network operators.

iBasis and SK Telink Take the Lead
iBasis and SK Telink are providing the IPX interconnectivity between the mobile networks of KPN and SK Telecom. The iBasis IPX is a single multi-service IP interconnect service to interconnect operators on a global scale with guaranteed quality and security, and offering mobile operators high-quality routes, redundancy, and diversity.

So, besides national VoLTE, we are proud to now expand the horizon with international VoLTE. If you are interested in learning more please contact Kees Hol, Product Manager for VoLTE at iBasis

Making 2017 a Profitable Year!

It’s with great pleasure that I welcome you to the first 2017 edition of iBasis mobile newsletter. Since joining iBasis six months ago I have been amazed by the tremendous opportunities and momentum I have observed in our industry: iBasis welcomed 20 new mobile customers in 2016, and this positive trend has continued into 2017.

We are strongly committed to help you deliver the best quality of experience, with the flexibility and smart customization required for you to harvest the new growth opportunities in this exciting and challenging environment.

We are focusing all our efforts to help you prepare with the right IPX architecture, analytics support and models to leverage the current roaming opportunities and the emerging growth in the exploding global IOT sector.

We expect 2017 to be a pivotal year, especially as the new EU regulation will be fully implemented and any premiums for international calls will phase out. Roam like Home plans are impacting all regions, challenging all of us to keep up with data and video traffic demands while also reducing costs. Over the past year, with acceleration during the last quarter 2016, we have ensured that the iBasis IPX network, enhanced with our InVision advanced analytics tools, is adequately prepared to serve your growing international traffic with predictable cost and consistent quality.

We know that you can experience significant variation in bandwidth needs, with extreme peaks in summer. Traditional interconnect and pricing won’t work anymore. So, we designed models that are cost-efficient, predictable, flexible, scalable and high-quality for both data and signaling: these customized models can match cost against pressurized revenues. Plus, with our service management team, we put in place the right organization to be responsive and flexible in order to enable you to make 2017 profitable while delivering the best roamer experience.

With LTE becoming the preferred network in use both in terms of subscribers and in terms of traffic, we know that Voice over LTE will follow. We are experiencing rising demand for VoLTE interconnects and expect this to expand in 2017. Many new mobile operators, mainly in Asia and in Africa without legacy 2G/3G networks, absolutely need Voice over LTE to satisfy their customers, and we are working with many of you on interconnect implementation projects. Our multiservice IPX is fully enabled not only to smoothly deploy VoLTE interconnects but also to ensure VoLTE roaming roll-out in both LBO and S8HR scenarios.

The roaming market is in a state of rapid evolution and disruption with the emergence of new IOT/M2M companies providing new kinds of connectivity for a very diverse range of devices and applications. It represents an exciting opportunity in terms of new pockets of traffic and revenues. I hope to meet many of you in the upcoming months, and I look forward to discussing further how we can help make 2017 a more profitable year for you.

VoLTE of People

The fifth generation (5G)
Today, 5G is the new buzzword. This fifth generation of mobile networks will offer a wide array of considerable improvements compared to 4G. Think of the capacity it will be able to hold, such as streaming live television via 5G home internet or data to and from autonomous (“driverless”) cars. The latter may need 5G to really kick into action. In addition to much higher data rates, more efficiency and less latency, an important aspect of 5G is that it is capable of supporting a whole new world – one where all types of devices are able to communicate with each other. This is also referred to as The Internet of Things (IoT) in which everything (humans and machines) is connected.

The fourth generation (4G)
Notwithstanding the promising outlook of 5G, we already have 4G/LTE, which has many benefits. As an example, LTE offers a radical change in how voice is treated over the mobile network: Voice over LTE (VoLTE). VoLTE brings faster call set-up time and much better voice quality. According to the GSMA, in October 2016, 91 mobile operators introduced VoLTE in their network and another operator is added to that list every week, on average. South Korea has the honor of being the first country in the world to introduce VoLTE. In 2012, three Korean mobile operators provided this enhanced voice service to their mobile subscribers.

A Connected World
Part of the 5G buzz is this notion of a connected world. This makes me think about the world of today in which we already have a large number of existing VoLTE networks, though not connected to each other. Why do mobile operators introduce VoLTE to their domestic network but withhold from their customers the advantages of VoLTE on a global scale? Why do they spend time and money on introducing VoLTE, but then cease to invest in the interconnection for VoLTE? VoLTE roaming may be an often-discussed topic, but VoLTE interworking is not yet high on the MNO list of priorities. A lack of additional revenue generation by VoLTE interworking is often heard as a possible reason for inhibiting this development. This may be true, but OTT providers do not wait; they continue to enhance and market their voice applications to present a compelling alternative that challenges the incumbent providers. VoLTE offers unique benefits, especially with its effectiveness (both in terms of cost and set-up time), and seamless, quaranteed quality.

With VoLTE interworking, directly or via an IPX hub, mobile operators can benefit from end-to-end HD voice quality and a global VoLTE reach in a cost-effective manner. In contrast to OTT players that provide a free calling app only within their own domain (“walled gardens”), the call quality with VoLTE interworking crosses network boundaries and helps MNOs distinguish themselves from OTT players. In South Korea, all of the country’s VoLTE-enabled subscribers are now able to make VoLTE calls across different mobile networks, thereby enjoying all the benefits that VoLTE has to offer.

What’s the Next Thing?
The popular answer is the Internet of Things, of course, in which all manner of devices ride the best possible network connections, and yes, that’s massive. But, we’re really not done connecting people in the best possible way, yet. So, in my view, the “next thing” is for other MNO’s to follow South Korea’s example in interconnection. Then the world will move from a situation with a few select interconnected VoLTE networks, to one with ubiquitous VoLTE service, a VoLTE of People (no doubt talking about the Internet of Things)! As an experienced voice and IPX provider, iBasis has the experience to support you in creating this connected VoLTE world. Learn more here.

Addressing the Vulnerabilities of VoLTE

Mobile operators around the world are launching Voice service over their LTE infrastructure (VoLTE) as the primary voice solution for their LTE subscribers. Unlike traditional circuit-switched voice, VoLTE exclusively uses IP packets over the LTE core network. Regardless of whether the call is domestic, international or roaming, is free of charge to the end user. Such a collective operational decision among the GSMA community simplifies the process of billing and settlement among MNOs, however it introduces a vulnerability for exploitation from some adversaries.

How Is VoLTE Like An Election?

When it comes to decision-making, as a general rule, people like to be presented with options. That’s certainly true in political elections. Sometimes the differences between options is very clear and it’s easy to express a preference. Other times, there are trade-offs and the choice is more difficult.  One has to carefully evaluate the potential long-term impacts of either choice. This is where the similarity with VoLTE, and specifically VoLTE roaming comes in.

Voting for International VoLTE
A logical next step for a mobile operator, after having launched VoLTE domestically, is to select the method for providing international VoLTE roaming to its subscribers. The number of domestic VoLTE networks is growing at the rate of about one launch per week. So inevitably, a very large number of operators will need to make a choice for a VoLTE roaming method, and possibly struggle with the available alternatives.

VoLTE Implementations

The number of operators with VoLTE launched has grown exponentially in the past few years, starting with 3 in December 2012, to 82 in August 2016 (source: GSMA).

Available Choices for VoLTE Roaming
Today, operators can provide roaming with a fallback to 3G roaming. However, if an MNO wants to reap the benefits of VoLTE to its full extent, the 4G roaming methods as defined by GSMA – S8 Home Routed (S8HR) and Local Break-Out (LBO) – are the future-proof way forward. But, like opposing candidates in an election race, they come with trade-offs.

S8HR is gaining traction in the market, due to its simplicity and potential for shorter time-to-market.

One result of S8HR is the transition from voice roaming minutes to data roaming packets. This change brings along a drop in revenues for the visited network, as the gain in data roaming revenues doesn’t compensate for the loss in voice roaming revenues. This effect may sound attractive for the home network operator, as S8HR will lower its roaming costs, but the flip side is that the wholesale department of this home network operator will lose mobile terminating revenues.

The S8HR voice minutes are now treated as data. They are transported back to the home network, bypassing the wholesale/carrier department of the operator, and revenue is no longer generated with the termination of voice into the home network. Depending on the specific situation of the mobile operator – whether more inbound or outbound roaming – S8HR can also make the net spend less favorable.

Stay Tuned!
Watch this space for more to come on the tradeoffs of LBO.

iBasis: A Leading International Voice Carrier For 20 Years

On August 2 2016, iBasis celebrated its 20th anniversary. Compared to our parent company KPN that counts more than 160 years of service, 20 years sound very young and brash. On the other hand, in ‘just’ 20 years iBasis has become one of the three largest carriers of international voice traffic in the world. Today we still are the world leader in that space.

The broadening of our services
With our global network and many years of experience with IP Communications iBasis continues to enable its customers to be internationally successful. Besides connecting international traffic, iBasis provides signaling and LTE roaming-related services that offer added value to mobile operators around the world. Among our customers are thousands of fixed and mobile network operators, VoIP and OTT providers (Over-The-Top). iBasis specializes in connecting fixed and mobile networks and builds bridges between different technologies, such as traditional TDM telephony, IP eXchange and now also LTE.

Continuing to innovate
As the world keeps turning, we continue to develop our communication services to serve our customers and make what’s next work globally. Besides strengthening the development of our Value Added Services for Voice, we are working on several other innovations. One example is ‘Next Gen’ Roaming Connected Cars in Europe with Cubic, where the car functions as a connectivity platform.

But today we also pause a moment to commemorate this milestone. 20 years is definitely an achievement worth celebrating. It is the result and hard work of an international team across the globe. A team I am very proud to be able to work with.


Happy Anniversary iBasis!
