The Move to Software-based Telecom Infrastructure (NFV) is On

July 21, 2015

About a month ago Erik Linask, Group Editorial Director at TMC, asked me for my thoughts on network functions virtualization (NFV)—you can read the entire interview here.  One question he asked was why NFV adoption seems to be increasing.

My perspective on this is that, over the past few years, there have been more and more software-based network infrastructure products deployed; they are scalable, telco-hardened and cost-effective.  At the same time, cloud-based enterprise solutions such as Salesforce.com have shown powerful OPEX and CAPEX models.

There is Considerable Intelligence in Signaling Messages

July 14, 2015


I’ve written about mobile value added services (VAS) multiple times over the years.  While there is still a lot of money to be made with mobile VAS, there is no denying the fact that applications from third party businesses that use the cellular data network—so-called over-the-top (OTT) apps—are eating into traditional mobile VAS. Famously, SMS/texting revenue is declining due to next-generation communication services like What’s App, Facebook messaging, etc.

However, that doesn’t mean that all Mobile VAS is declining.


The Role of Media Servers in NG911 and e911

July 7, 2015

While we take for granted now that we can use text, video and data to communicate with each other, this is not yet the case for emergency communications. However, enhanced 911, or Next Generation 911, aims to enable emergency services to handle text, video or hi-def pictures, which is clearly invaluable for ensuring individual and communal safety. For example, the proliferation of smart phones has made it so that citizens can text police departments when in need of help. Or, they can send pictures of videos of emergency situations, which help enhance and accelerate the response of emergency services.

VoWiFi Will Play a Critical Role in Extending Voice Coverage

June 30, 2015

Voice over WiFi (VoWiFi)...what’s the big deal?  For instance, I can already engage in VoWiFi with some VoIP clients that are downloaded to my phone. The difference is that the subscriber, who may still be actually using the carrier data network, is now from a certain perspective not using the carrier network because the individual is now interacting with some kind of over-the-top content (OTT) app. 

From a carrier perspective, that’s not really acceptable as they are losing the main interface to the subscriber and becoming just a dumb pipe, which most of them don’t want to do since they’d lose significant ability to obtain additional revenue from the offering of value added services.

It's VoLTE Time

June 23, 2015



It’s Voice over LTE (VoLTE time). As we all know, the numbers of LTE networks and subscribers have been growing tremendously; the former, for instance, is expected to reach 460 by the end of 2015. And we’ve all enjoyed getting data via a more landline-like experience thanks to rapid LTE network connectivity.

From a voice perspective, however, VoLTE is still in its early developmental phases.



Video and Voice over LTE/ WiFi Requires a Media Server

June 16, 2015

With the LTE World Summit coming up next week, there will be much discussion about voice and video over LTE as well as voice and video over WiFi. I’ll be writing some blogs about those topics in the weeks to come.

There is no doubt that voice and video over LTE and WiFi is increasingly emerging; however, it’s  important to remember that the world is not still just a bubble of LTE networks. That is, if you want to place a call from an LTE network to a 3G network, signaling conversion must still take place (see my last blog for more on this). 

The Importance of 3G Interworking with Diameter and RADIUS

June 9, 2015


The number of LTE networks is expected to be 460 by the end of 2015, supporting approximately 500 million subscribers at the end of 2014, according to data from GSMA Intelligence. There is continued phenomenal growth in sight, but that doesn’t mean 3G should be forgotten. In fact, it’s quite the opposite; 3G connections will continue to grow at least through 2020 where the forecasting ends, also according to GSMA. It’s likely to continue growing beyond that, too.


Dialogic Worldwide Road trip and Why Software and NFV Aren't the Same Thing

June 2, 2015

Dialogic kicked off a worldwide roadtrip for our customers and prospects focused on meeting the needs of the service provider community. With a packed agenda and room in Tel Aviv last week we got off to a good start. Key items discussed were VoLTE and VoWiFi, Telco Apps, NGN Transformation, Signaling Interworking, WebRTC and Network Functions Virtualization (NFV). 

ITW Leads the Way Helping Wholesalers Identify New Revenue Streams

May 26, 2015

A few weeks ago I attended International Telecoms Week (ITW), an annual gathering of the global wholesale telecommunications community. This is definitely a show in transition since its core customer base, telecom wholesalers, are stressed out.  That is, voice wholesale minutes are now intensely competitive—and even potentially declining—due to a slowdown in growth. As a result, voice wholesalers are trying to figure out how to address this issue in order to continue thriving. 

Advancing Texting for the Contact Center

May 19, 2015

Last week, we explored texting within the contact center realm.  As texting becomes more prevalent in the contact center, there will be a lot of interesting use cases for expanding text as a customer service avenue.  These use cases will be similar to many years ago when the “call” center transformed into a “contact” center due to customer interactions taking place over the Web.  In other words, it’s the story of the mobile on-ramp to the Internet.
