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.

The Six Degrees of Mobile Data Plan Innovation: It's Not All About Data- Mobile Voice and Messaging Share Plans Offer Plenty of Appeal

Alcatel-Lucent’s Rich Crowe continues the Six Degrees of Mobile Data Plan Innovation blog series by examining the degree to which consumers are interested in share plans that include unlimited voice and messaging but don’t include data.

The last Six Degrees blog explored consumer attitudes toward two different mobile share plan options: sharing data only and sharing voice, messaging and data. This blog will explore attitudes toward a 3rd option: sharing unlimited voice and messaging — but not data — across multiple devices or subscribers.

FCC UNE-P Rules

February 5, 2005

The FCC released its much anticipated UNE-P rules for ILECS. These rules basically undo requirements by incumbent carriers to have to lease their lines to competitors at cost-based rates. There are some exceptions… For example, where there is limited competition. The rationale is that LECs will be able to invest more fully in building infrastructure if they know they don’t need to share these investments with competitors.



An insightful quote from the 100 page-plus order follows:

This Order imposes unbundling obligations in a more targeted manner where requesting carriers have undertaken their own facilities-based investments and will be using UNEs in conjunction with self-provisioned facilities.  By adopting this approach, we spread the benefits of facilities-based competition to all consumers, particularly small- and medium-sized enterprise customers.  We believe that the impairment framework we adopt is self-effectuating, forward-looking, and consistent with technology trends that are reshaping the industry.  As we recognize below, the long distance and wireless markets are sufficiently competitive for the Commission to decline to unbundle network elements to serve those markets.  Our unbundling rules are designed to remove unbundling obligations over time as carriers deploy their own networks and downstream local exchange markets exhibit the same robust competition that characterizes the long distance and wireless markets.

The bold text above is quite true as VoIP has increased long-distance competition by an order of magnitude.

Inter-Tel 5000 Network Communications Solutions

February 5, 2005

Back in 1995 I published a magazine called CTI and the computer telephony/CTI market was what the VoIP market is today. The technology wasn’t the same but the market was similar in that it allowed computer systems to speak with phone systems and it ignited tremendous growth and new paradigms in communications. At one point (if you can believe it), VoIP was just a small subset of the CTI market and in fact Internet Telephony Magazine was a spin-off off of CTI Magazine.



Linking computers and phones together today seems like no great feat but back in the 80s it would cost you hundreds of thousands of dollars to get some interoperability going and you could do it only if you had an IBM mainframe and Rockwell ACD.

Boring Apprentice, Nescafe

February 4, 2005

I can’t fathom how boring a TV show could be. Last night marked the worst apprentice I have ever seen. Neither group did anything interesting and the task last night of promoting Nescafe Coffee was fairly similar to the toothpaste (was it Crest Whitening Expressions) assignment from a while back.


Sadly, the performance on this event didn’t even measure up to the “toothpaste” episode.

900% Cable VoIP Growth

February 3, 2005

I must have been asleep a few days ago when Greg Galitzine blogged about the massive growth in the cable VoIP market. half a million cable VoIP subscribers are voiping together while in 2003 the number was closer to 50,000!

I suppose this is why Time Warner telecom has become a big part of Internet Telephony Conference & Expo in a few weeks. I may be going out on a limb but this event will likely be the largest VoIP show the world has ever seen from an attendance standpoint.

Patents as WMD

February 3, 2005

Yes it's true, since we couldn't find any real WMDs in Iraq, the BBC suggests we look for patents instead. Just kidding. A story titled Open source leaders slam patents discusses how Linux founder Linus Torvalds said software patents were a problem for the open source movement.

There was a Linux summit this week in California (my invitation must have been lost in the mail) where a number of high-powered people in software development complained about Microsoft using intilectual property as weapons.

Packet8 Interview

February 3, 2005

Packet8 has might a splash lately with rapid subscriber growth. They don't get as much press as Vonage and AT&T but they are growing quickly and I decided to interview Huw Rees,  the Vice President of Marketing & Sales at 8x8, the parent company of 8x8. He has some great comments and I am surprised about the WiFi telephony answer. Please enjoy the interview.
