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.

Good One

FCC on May 19th

May 13, 2005

There is a good chance I will have my second daughter on May 19th and this is the day the FCC will hold its open commission meeting to discuss wireline competition. More specifically they will be discussing E911 and how VoIP service providers will have to enable 911 on their networks.

I am watching these events with a bit of concern and at the same time hope that whatever the commission decides VoIP providers will be able to implement quickly. Hopefully the process will be painless as well.

Still the FCC could decide anything and perhaps that is what scares me just a bit. They could make it very difficult for VoIP service providers if they so choose.



Cold Stone Creamery

Are you kidding? I get to write about a topic I have far too much knowledge on? Ice cream?? Great news. And I get paid?

Cognitronics Loss

May 12, 2005

I had to write this when I saw that Cognitronics lost money in its latest quarter. The company actually had a net loss of .8 million compared to 1.4 million a year earlier so they are slowly growing – or at least bleeding less money than a year ago.

The following statement from Brian Kelley in the Cognitronics release struck me:

"The telecommunications marketplace continues to make headlines in 2005 as two more of the largest telecommunications service providers announced their intentions to merge. In the absence of real growth, consolidation rules," said Brian J. Kelley, president and chief executive officer of Cognitronics. "After years of excess infrastructure build-out, these service providers, our customers, continue to maximize the capacity of their existing network infrastructure.



Packet8 Slams Vonage

May 12, 2005

OK perhaps the slam is indirect but the message is loud and clear… Ours works and yours doesn’t. Today Packet8 announced that their VoIP ser vice has 911 that works in 2,024 rate centers covering 43 states. The company put out a release today and in it they say:

Unlike "911" services marketed by some other VoIP providers, whereby a call to 911 is intercepted by the VoIP provider and forwarded to a regular, non-emergency telephone number, Packet8's E911 call is routed as 911 emergency traffic and is accompanied by caller information.  Packet8's E911 services enable emergency personnel to ensure that callers receive the exact same response that they receive from 911 services provided by landline incumbent telephone carriers.  The Packet8 E911 implementation routes a subscriber's call directly to a 911 operator and eliminates unnecessary dialog about callers' whereabouts, which is vital in cases where a caller may not be able to verbally communicate due to an emergency condition.


Boy, I wonder who they are talking about. As I wrote about today, Having the best product doesn’t mean anything, it is the best marketer than wins every battle.


I Can Hear You Now, Can You?

May 12, 2005

Verizon Wireless I love you, I hate you, I love you, I hate you. Why must you have the best wireless service? Extremely fast EVDO access? Calls that rarely drop and then put me through hell daily?

I used to use a GSM network phone and the service was terrible.

Dear Mr. VC

May 12, 2005

To be more politically corect: Dear Mr. or Mrs. VC

Many of my readers are in the VoIP community – you know who you are… You were doing VoIP in the late nineties – when it wasn’t fashionable and you used to call it IP telephony or Internet telephony. I am running into more and more of these people and they often ask me if this time the IP revolution is for real. The answer is absolutely.

As President of a leading publishing and trade show company having been involved in VoIP since its inception and having launched the first magazine in the space, I think I have a unique perspective on the market. I am seeing more optimism and sales than at any time before.



VoIP Quality Study

May 11, 2005

I have been deluged with requests about this study. The last time I wrote about it I told you that Packet8 was the quality leader so far. I haven’t had a chance to read this as I am on my way to visit a number of VoIP companies today and am running late. Enjoy the release.
