Wi-Fi Offload/Roaming Part 3: Diameter and LTE Interworking Is Crucial

June 17, 2014

In my last blog, I discussed the architectures needed to roam between Wi-Fi and 3G/4G networks. In order to enable interoperability between the different architectures, a mediation and interworking platform is required to support the different scenarios in which RADIUS, Diameter and SS7 are used.

RADIUS is critical for interworking with Wi-Fi networks. Authentication and authorization of roaming subscribers is performed through RADIUS messages over an inter-operator interface between the visited network provider and home service provider.

Is WebRTC for Real or Not?

June 10, 2014

57 percent of respondents to our WebRTC Impact Survey have WebRTC solutions already in development.

Next week, Dialogic will head to Atlanta for the WebRTC Conference & Expo.  While there are many WebRTC-focused events out there offering demos and expert advice, I consider this one to be the best.  So as we prepare for this year’s Expo, now is a good time to ask: Is WebRTC for real? 

Wi-Fi, 3G/4G Roaming and Interworking Architectures

June 3, 2014

In a recent blog, I discussed Wi-Fi roaming and the wireless roaming intermediary exchange (WRIX), which is similar to an internetwork packet exchange (IPX) for Wi-Fi roaming. The WRIX is broken down into three levels that cover the various interactions needed between operators to support roaming.

The first level, WRIX-i (interconnect), specifies the interface between the visited network provider (VNP) and the home service provider (HSP). WRIX-i requires the use of RADIUS authentication, authorization and accounting (AAA) procedures and some specific attributes associated with access and accounting services.

OTT is / is not a threat to interconnect carriers

May 27, 2014

Two weeks ago, I traveled to Chicago to attend International Telecoms Week (ITW), the annual meeting for the wholesale telecommunications community. One morning, I was reading the show news daily and sipping my morning coffee when I came across an interesting article. It was about whether the wholesale market thinks over-the-top (OTT) technology is a threat or an opportunity. The article cited a Capacity Magazine survey that showed 82 percent of the wholesale market leaders surveyed see OTT as an opportunity.

LTE Is Not the Answer - But WiFi Might Be

May 20, 2014

Right now, LTE is in its heyday. Carriers are doing all they can to expand coverage and improve speeds, and those lucky enough to be using it probably experience great service. But as mobile data use increases, that honeymoon period will end as networks get clogged and overloaded.

As that happens, WiFi networks will become an increasingly important way for carriers to improve coverage and capacity.

Could WebRTC Initiate Changes In the Contact Center?

May 13, 2014

Last week, I introduced some cool goings on in the contact center, such as cloud, smartphones and video. This week, I’ll finish my thoughts about how the contact center will continue to morph.

Integration of social media is also becoming more critical. If there’s outrage over a product defect social media can give you a read on that backlash so you can take appropriate action.

What's Happening In the Contact Center?

May 6, 2014

When I started writing my blog about why the fax is still relevant a few weeks ago, it got me thinking about the contact center in general. I spend a lot of time talking about mobile networks and service provider-related things like signaling, but in my early years at Dialogic, I learned a lot about contact centers (they were called call centers back then), and that is still an important business for us.

The contact center has traditionally been a rich area for introduction of new technologies, given that there is a dual need to service customers effectively while keeping costs down as much as possible. This dichotomy has spawned use of new communications innovations, such as VoIP, quickly.

Predictions For International Telecoms Week 2014

April 29, 2014

International Telecoms Week (ITW), the event that brings the interconnect market together to conduct business, is in two weeks. Historically, ITW has focused on minutes exchange for landline networks. But mobile networks via IP packet exchange(IPX) are now entering the picture, and IPX is set to be a hot topic at this year’s conference. With LTE coming to the forefront, IPX is becoming even more important because it provides a way to enable LTE roaming.
