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.

Telchemy, NexTone News

February 28, 2005

A natural partnership between Telchemy, a VoIP performance management company and NexTone a session border controller maker has recently taken place.

Specifically, NexTone will feature VQmon/SA (Stream Analysis) call quality analysis algorithms in its MSC product for carriers and enterprises to use in monitoring, diagnosing, and managing network call and packet-related problems. NexTone's MSC enforces QoS policies across the network edge, thus enabling carriers and enterprises to route, manage, and control real-time traffic at minimal cost.

NexTone's MSC is deployed at the network edge and operates alone or in conjunction with a core call control engine such as the NexTone Multiprotocol Signaling Switch (MSW).Ā  The MSC's FlexPeer capabilities, consisting of dynamic call admission control, SIP/H.323 interworking function, network address translation (NAT) and VoIP firewall functionality, provide IP carriers with flexible, secure interconnections to other IP-based carriers and enterprises.

Telchemy's VQmon/SA is used in mid-stream routers and switches and in VoIP test equipment, e.g., probes and analyzers, to support both non-intrusive monitoring of live calls and active test calls for on-demand troubleshooting. It further supports the Internet Engineering Task Force (IETF) RFC 3611 (RTCP XR) Protocol and the new QoS reporting protocols for International Telecommunications Union (ITU) H.323, H.248 and G.799.1 standards. VQmon/SA provides:

Listening and conversational quality metrics
MOS scores and R factors
Detailed packet/RTP statistics
Jitter buffer emulation
RTCP XR encoding/decoding with dynamic calibration

It should be a matter of time before other session border controller manufacturers make similar announcements.

UN of VoIP

February 28, 2005

According to the Miami Herald, in an article titled Tangled Web Lines (free registration required) ITEXPO had lines of people five-deep at many of the more than 100 booths!

To take a direct quote from the article:

Crowds have exceeded seating at some sessions. And the exhibition hall of service providers, which is open free to the public through today, had lines five-deep at many of the more than 100 booths when they opened Wednesday evening.

I'm speechless and humbled by this awesome praise by the Miami Herald journalists!

As a barometer of our VoIP industry, ITEXPO has shown me that the world is embracing VoIP like never before.







Do Not Call List Hurts MCI

February 28, 2005

MCI (chart) sales recently fell 10% in theĀ 4th quarter. Revenue from consumer and small business customers dropped a full 21%! Long-distance subscriber counts are the reason according to MCI. Perhaps every Vonage user was once using MCI?

Seriously, the company blames its inability to use telemarketing as a reason for their decrees in new customer acquisition.

MCI Selling Low?

February 28, 2005

Last Friday MCI CEO Capellas said in response to MCI shareholders against the Verizon deal, "In Verizon we see a partner that compliments our business," he continued, "We recognize the input of shareholders. We acknowledge receipt of Qwest's proposal and remain respectful to all parties."

Qwest is willing to set a third bid for MCI, even though their latest bid is a billion dollars greater than that of Verizon. The only thing Qwest wants is some respect. They want to talk with MCI.

ITEXPO Wrap Up

February 25, 2005

It has been an incredible week and I can tell you now that the excitement level in VoIP has never been so great. People from over 70 countries came to ITEXPO this week and the attendees were hungry for information. Exhibitors told me that many of these people weren't neophytes. Many had already implemented VoIP and were looking for other voice components such as QoS monitoring to put in their network.

Virus Kills The Presentation?

February 25, 2005

That should read "Amost Kills the Presentation." At some point last night, probably when I was downloading a photo for my presentation around 1:00 AM I caught a nasty virus. My virus scanner called it a Trojan Horse. I didn't write down the name as I didnā€™t want to get too friendly with it I use AVG AntiVirus and the program got rid of the virus but not immediately. In fact I was somehow stuck in an infinite loop of new IE windows opening up while I was trying to save my PowerPoint Presentation.

The Busiest Show Ever

February 25, 2005

This is a phrase I heard repeatedly at the most successful ITEXPO EVER! Thank you all for coming and making this show such a success. We had an amazingly large audience and exhibitors told me this is the most qualified audience they have ever witnessed at a show while conferees said they were happy with our conference program and appreciate the fact that TMC values their educational experience.

If this ITEXPO is not a barometer of the industry's success and phenomenal growth, I am not sure what is.

Without all of you... Attendees and exhibitors, we can't have great shows so thanks for coming in droves and I am humbled by all the compliments you gave me over the last few days.

My thanks also to the TMC team for working around the clock to help keep up with the demands of this event.

Witness the "Mass of humanity" at ITEXO Miami 2005.







Open-Source Debate

February 24, 2005

What I really love about ITEXPO events is the networking opportunities and how much I can learn in a few minutes of relaxed conversations with colleagues. I had a chance to hang out with close friends and new ones in the industry last night. I got to see Mark Lyons from Vonage for example and noted he is one of the most passionate people in VoIP. He is the VP of Sales -- VAR Channel and was sharing stories of meetings he has had in China and more.
