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.

Windows XP Media Center Edition 2005

Media Center Edition 2005

I was just reading about the launch of Media Center Edition 2005 and came across this link: Microsoft to tune up Media Center PC | CNET News.com As I just blogged, I want to buy a Sony model running the new Media Center Edition 2005, however according the link, "The machines are part of Sony's existing "R" series of Vaio Desktops. In addition to sporting the new OS, the machines add faster processors and larger hard drives as well as the option to automatically create a backup of data using RAID. For now, Sony's machines stick to offering a single TV tuner."

One tuner? Are you kidding me???!

Media Center Extender

Linksys Wireless A/G Media Center Extender (WMCE54AG)

I have over 167,000 Sony points to use up, so I have been itching to buy a Sony VAIO running Windows Media Center PC for some time now -- which has TiVo-like aka Personal Video Recorder (PVR) functionality. Now with the new Microsoft Media Center 2005 operating system released today, no doubt Sony will come out with the new operating system which has some cool new features. I won't go into the new Media Center 2005 features in this blog entry since I want to talk about wireless Media Center Extenders that work in conjunction with Media Center PCs to wireless transmit your Media Center PC content to anywhere in your house! In fact, one of the reasons I didn't bite the bullet was my PC was so far away from my 65" Mitsubishi television set that I would have to "snake" wires in my house from the PC to the TV, that would no doubt be grounds for a divorce!

Vonage E911 news

October 12, 2004

Thought I'd share this news about Vonage and E911 using Intrado. As you know, one of the knocks against VoIP is 911 support in the event of emergencies. Of course, I have heard from a few people in the VoIP industry "knocking" against using Intrado's database. It could be due to the price-tag of using Intrado's database or it can simply be the people in the VoIP industry knocking them since don't have E911 support themselves.

AT&T CallVantage Behind Router

October 12, 2004

One of the knocks against AT&T CallVantage was that it doesn't work behind your existing home router/firewall. Their nemesis, Vonage, is able to handle being behind or in front of a firewall - a huge competitive advantage, especially for the security-conscious techies that don't like having any device in the front of the firewall.

Well, Andy Abramson brought to my attention that this is no longer the case - AT&T CallVantage does indeed support being connected behind a firewall, as confirmed by this AT&T CallVantage How To link: AT&T CallVantage

Though I did read somewhere else that contradicts this and it stated that AT&T DOES NOT support having the telephone adaptor (TA) behind the router/firewall, but that they "will soon support such a configuration".

I guess AT&T is moving so fast to add features and functionality to CallVantage the left hand doesn't know what the right hand is doing!

VoiceEclipse New VoIP Service Provider

October 11, 2004

Yet another Vonage-wannabe I recently discovered. They have a $29.95 unlimited plan with 2 phone numbers included (at least that is unique).

They also offer $12.95 for 1 phone number and 500 minutes and $24.95 for 2 phone numbers and 1000 minutes.

When I clicked the About Us link it said:
StarNet, Inc., founded in 1994 by Chief Executive Officer Russ Intravartolo, is a leading provider of dial-up Internet access and related products and services in North America. Through its state-of-the-art, fully owned MegaPOP network, StarNet provides reliable, high quality services designed to serve the consumer markets and the small to medium-sized ISP.

AT&T and LinkSys VoIP deal

October 11, 2004

It came as no surprise to me that AT&T and LinkSys would ink a deal to offer AT&T CallVantage on Linksys's home broadband router product line. Now, LinkSys has special VoIP customization for Vonage, AT&T CallVantage, and Verizon VoiceWing.

The Ethernet version is currently available directly from AT&T, and Linksys expects that all versions will be available at retail outlets such as Best Buy, Circuit City, Staples, and Office Depot later this month.

I hope the packaging is clear which VoIP provider you are getting when you buy it at a retail store (such as a Best Buy or CompUSA.) It would really suck if you planned on signing up with one VoIP provider but bought a LinkSys model with a different VoIP service provider embedded inside.
