Analyzing the mobile devices connected to today's network

By: Patrick McCabe, Senior Marketing Manager, Alcatel-Lucent

We know from our own experience and from anecdotal evidence that mobile devices are proliferating and that mobile data usage is growing rapidly. This tremendous change necessitates change to the underlying network, too. But in order to make the best choices in terms of infrastructure investment, mobile service providers must have accurate data showing what devices are being used and which consume the most data and signaling resources.

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.

Texting and the Contact Center

May 12, 2015


I’ve periodically written about the changing contact center, from speech analytics to WebRTC, multiple times. Another interesting trend emerging is the use of text messaging within the contact center. It is a bit of an old-school method, but text is an efficient and direct way to deliver information to customers. In fact, a widely quoted statistic from a 2014 Harris Poll survey indicates that 64 percent of consumers with texting capabilities would prefer to use texting over voice as a customer service channel.

An IP Packet exchange (IPX) is a private managed network, defined by the Groupe Speciale Mobile Association (GSMA), over which service providers can offer network connectivity and service interworking on a commercial and competitive basis between not only mobile operators, but also fixed and converged service providers, cloud operators and application service providers.

A multilateral IP service hubbing arrangement enables a service provider to connect to multiple termination providers through one single connection between, facilitated by an IPX operator. What that effectively allows the service provider to do is to deliver end-to-end services to its customers without the need to establish individual bilateral connections and agreements with each of the hundreds of fixed and mobile operators around the globe. However, bilateral arrangements are also supported through an IPX, in case that particular interconnection model makes the best sense. 


NFV vs. SDN

April 28, 2015


I have written in the past about NFV and SDN being complementary. Now that some time has gone on, I wanted to expand on that. It is definitely still true, but being at Mobile World Congress crystallized my thinking on this subject.

First NFV is about providing virtual network functions.


Country Music and Wi-Fi Offload

April 21, 2015


This past Sunday night I attended the 50th annual Academy of Country Music (ACM) awards, hosted at the AT&T Stadium outside of Dallas, Texas.  If nothing else, this certainly represented the most cowboy boots in one place I’ve ever seen.

So why am I writing about this?  Well, I have AT&T service and as I approached the stadium I got a text message that said “AT&T Wi-Fi is active near your location.
