We ask the experts: How can exceptional QoE be achieved in VoLTE networks?

By: Jean Jones, Director, Wireless Marketing, Alcatel-Lucent

What does voice over LTE (VoLTE) offer your subscribers? Better voice quality, including HD voice. Rich communications with messaging and video. And whatever inventive applications you choose to introduce. In other words, VoLTE can provide a superior quality of experience (QoE) for subscribers and give you a competitive edge — particularly when your service operates at its best.

In my last blog[CCE1] , our experts explained why an end-to-end strategy is the key to maintaining peak VoLTE performance. Now we’ll look at how this strategy gets put into practice to optimize real-world service offerings. The information here is based on interviews with Luis Venerio who works with our VoLTE Readiness Services team. And his observations come straight from his experience on VoLTE deployments that serve millions of subscribers.

How signaling spikes affect networks: 3 real-world examples

By: Josee Loudiadis, Director of Network Intelligence, Alcatel-Lucent

Data and signaling growth are usually good news for network operators, since growth often translates into higher revenues. But when growth is averaged over a month or quarter, the daily highs and lows of network activity are smoothed out. And signaling spikes remain hidden within the averages. These spikes can overwhelm available signaling capacity, which impairs the customer experience, as well as the operator’s reputation.

What happens when a spike occurs? Typically, a CPU Overload alarm appears on various mobile nodes. And the Network Operations Center (NOC) immediately starts praying that the burst is short-lived and doesn’t go over maximum peak-rate capacity. Because when that happens, all consumers are denied service access. Then, the process of identifying the source of the problem begins. This can be arduous, because it often involves applications completely out of NOC control. And the issue can’t be resolved easily without solid network analytics that enables engagement with application and device developers.

That’s the reason signaling information is a crucial part of the Alcatel-Lucent Mobile Apps Rankings report and why LTE World 2014 devotes an entire pre-conference day to the topic. It’s also why this blog offers a closer look at how some real-world disruptive signaling spikes got started — and were finally resolved.

Mobile fax? Why do you need that?

July 29, 2014

Fax is an enduring technology. While you may think that fax is declining, some reports show that the market is actually increasing, especially in the areas of fax over IP (FoIP), fax service and computer-based faxing. In fact, the fax industry is predicted to grow to $2.795 million by 2018.

One new technology that’s taking off is mobile fax, which, as the name suggests, involves using your mobile phone as a fax machine.

When Does WebRTC Need a Media Server? Reason #7

July 22, 2014

Tsahi Levent-Levi’s white paper, “Seven Reasons for WebRTC Server-Side Processing,” details a variety of WebRTC-related scenarios that necessitate a media server. Last week, I wrote about reason number six: processing of the media stream. This week, I’ll discuss reason number seven, which deals with machine interaction.                                                 

When Does WebRTC Need a Media Server? Reason #6

July 15, 2014

In a recent blog about the current state of WebRTC, I mentioned that readers should check out an excellent white paper about seven situations in which WebRTC would need server-side media processing. Written by Tsahi Levent-Levi, a leading blogger at BlogGeek.me and WebRTC activist, the white paper gives a great overview and unique point of view about why media servers matter.

In the next few weeks, I will explore some of the seven reasons from Tsahi’s white paper. Today we’ll dive into reason number six: processing of the media stream.

The Top Five Tips for Transforming Your Legacy Switching Environment

July 8, 2014

Softswitches, once bastions of the “new” IP telecommunications environment, are now regarded as legacy equipment in some circles. Replacements to full IP multimedia system (IMS) environments are still in full swing, but that takes capital and operational expenditures (CAPEX and OPEX). Upgrading your old softswitch to a modern one can be a better way to go for many carriers. Why?

NFV and SDN: Diameter Signaling Controllers Join the Best of Both Worlds

July 1, 2014

 

In the Heavy Reading white paper, “Control Plane Orchestration: The Evolution of Service Innovation Attributes,” analyst Jim Hodges writes that the telecom industry has never before simultaneously experienced two foundational disruptive technology trends that are complementary. What is he talking about?

TADHack: Adding the Human Element to Communications

June 24, 2014

A few weeks ago, I attended a new developer show in Madrid called TADHack. It’s a smaller event and very different from the average conference. As soon as I walked into the venue, I noticed this weird green hue, kind of like I was in the Wizard of Oz. It had the feel of a nightclub, which was fitting since the developers were hacking late into the night.

TADHack is geared toward communications and voice developers, particularly over-the-top (OTT) communications app developers.

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.
