Why CSPs Will Retain a Strong Position in Video Services

By: Paula Bernier, TMC Executive Editor

Facilities-based service providers that own the access network are ideally positioned to distribute video both today and in the future, according to Chris Croupe, who works in strategic marketing at Alcatel-Lucent. Video comes in a variety of forms, its applications continue to expand, and this kind of content continues to multiply, Croupe notes in his recent TechZine posting, Future of video content: Evolution toward 2020.

Calls leveraging video have become widespread, he adds, noting that 59 percent of smartphone users under 35 years of age make at least one video call a month, and 37 percent of this group does so at least once a week.

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.

WebRTC Webinar Q&A #2 "Why WebRTC when we have Skype?"

April 17, 2013


“Why  WebRTC when we have Skype”?”

This is a really good question.   After all, Skype is the dominant real-time communications technology on the web with hundreds of millions of users and isn’t very hard to use. 


LTE / Diameter Interworking (Part 2 of 2)

April 11, 2013

Two days ago, I wrote a blog about Diameter Interworking use cases.  If you are a network operator, are these issues real? Well, they’re real enough that the 3GPP and GSMA have identified elements called Diameter Routing Agent (DRA),  Diameter Edge Agent (DEA), and Diameter Interworking Function (IWF), which is more closely aligned to the interworking described above.

Given that these issues are real, how do you address them?  For starters, operators need a box that connects the carrier LTE/IMS and policy control environment to existing 2G/3G/Wi-Fi and back office environments.

LTE / Diameter Interworking (Part 1 of 2)

April 9, 2013

Last week, I wrote a blog about Diameter protocol and its application use cases.  Since LTE uses it as a signaling protocol, operators have a need to interwork Diameter with the signaling technologies used in other mobile networks. This has given rise to the Diameter Interworking Gateway function, which moved onto the center stage at Mobile World Congress this year. It’s a critical element to enable the successful rollout of LTE and a seamless user experience across different networks.

WebRTC Webinar Q&A #1 "Is WebRTC 10 years too late?"

April 4, 2013

“Is WebRTC 10 years too late?”

To properly answer this question, one needs to take a position.  One position is to assume that all the VoIP “stuff” that came before Web Real Time Communication (WebRTC) is kind of useless.  But moving to a world where SIP, G.711, and H.264 are the dominant real-time communication protocols and codecs over IP networks is not useless. 

Diameter Use Cases

April 2, 2013

Diameter is the key signaling protocol used in IMS and LTE networks that enable applications running on those networks to authenticate, authorize and charge. In other words, your mobile applications, when running on these networks, are using Diameter protocol in the background to enable you to utilize the many apps on your smartphone or tablet. This includes, for example, a location-based service type of application (such as Foursquare or Yelp), or mobile payment (such as Square), or an Internet purchase (from an app store online retailer like Amazon).

Given the huge amount of smartphones and tablets out there that are either now running on LTE networks are that are expected to be LTE-enabled in the future, I predict that will be a big increase in Diameter signaling traffic.

The Contact Center's Continual Transition

March 19, 2013



The contact center is undergoing continual change as companies strive to make their operations more efficient and cost-effective.  This is one of the reasons the contact center has always been an innovator and a driver for new technologies, from VoIP to Web integration to speech recognition.  Now, contact centers are undergoing still further transformation because access to them is coming more and more from smartphones and smartdevices. Contact center operators must look at feasible ways to maximize investments while also integrating modern, media-rich communications that give customers more options.

Mobile Congestion and Radio Blogging and Podcasting

March 12, 2013

Over a month ago, I participated in a radio blog / podcast with Tech in Twenty.  The theme was mobile congestion.  Please listen to the 20 minute broadcast/podcast/radio interview since it was riveting! Seriously, it was fun, the interviewers Luis and Jennifer asked good questions and I think the interview is interesting.
