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.

Yealink SIP T-38G Review

June 17, 2013



The Yealink SIP T-38G Gigabit color LCD PoE IP phone is another impressive IP phone following in the steps of the Yealink T-28P that Tom Keating reviewed in 2010. Tom liked the 4-way arrow navigation keypad, which continues on the T-38G, making navigating on the color screen a breeze. The T-38P also features a very similar web admin page as the T-28P and like Tom I had no trouble adding the SIP credentials, configuring the NTP server, adding speed dials, and other various configuration options.

While referencing Tom's T-28P review for comparison to the T-38G, Tom has this noteworthy comment:
The web interface displays a message when the phone is registered so you know immediately if you put the SIP credentials in correctly. I have to say, I really loved how every change I made DOES NOT require a reboot.




Now Unclassified PRISM Docs Still Off Limits to Fed Workers

June 14, 2013

For a federal government riddled with scandals this news may not seem so important but it is indicative of the logic of government. The numerous documents which have been leaked all over the Internet regarding PRISM and countless other government spying programs are off-limits to Senate staffers. They have been asked by the Senate Security Office not to download documents which are potentially classified - even though everyone on the planet likely has.

The logic here is baffling...

TMC's New NFV News and Analysis Site

June 12, 2013

The move from proprietary hardware to software running on commercial off-the-shelf servers at the world’s telcos is one of the biggest transformations we will see this decade. Over time we can expect to see a number of network functions which used to be supplied by hardware vendors through proprietary boxes turn into software running on servers with Intel or ARM chips perhaps supplied by HP or Dell running VMware or some other flavor of virtualization. The concept is called Network Functions Virtualization or NFV. I wrote about the concept a while back in a post Metaswitch Asks: Are You Ready to be a Software Telco? and more recently in NFV-Based Software Telcos Need OSS/BSS Interoperability.

Will iRadio Kill Pandora?

June 7, 2013

34% of Internet radio users surveyed would switch to Apple’s iRadio and some believe this is a major problem for Pandora. I remember when Google was going public, similar research showed users would also switch to a better search engine given the opportunity. The challenge is many people are set in their ways and inertia keeps them from switching.

What Apple needs to do is make the radio integration so solid that you have no choice but to try it and perhaps like it better than the service you currently use.

Moped 2.0 Blends Social, Messaging and Cloud Storage

June 6, 2013

There are a plethora of apps to communicate but precious few bubble up to the top. Quite often a company comes up with an idea for a service which improves on another form of communications. Tweetdeck and Hootsuite come to mind as examples.

Another new option is Moped 2.0 which goes live as you read this entry and allows users to more easily communicate with their social circles while adding in the capability of sharing media.

A Billion WebRTC Endpoints Force Voice and Data Players to Adapt or Die

June 5, 2013


From an evolutionary standpoint regardless of whether we talk about nature or business, adaptation is a key to success in changing environments. During the industrial revolution in London a species of moth with a white color blended in with the bark of the local trees until soot from the nearby factories turned the trees black. Some darker moths were now camouflaged in the dark trees and eventually the species adapted and became black. When air quality improved, the moths over successive generations changed color again.

Your iPhone Could Get Hacked Through the Charger

June 4, 2013

As scary as it sounds – that iOS device which you thought was safe from hackers because Apple controls the App Store could get infected through a malicious charger. This is a major concern for IT departments who didn’t previously worry about Apple devices which were not jailbroken. It is now impossible to know which Apple devices have been infected meaning all of them are suspect.

An article on TMCnet by Steve Anderson explains that a group of researchers at the Georgia Institute of Technology discovered the exploit which can be duplicated via a device called a Mactans charger.

Yahoo! Should Buy Waze

If you haven’t checked out the TMCnet feature by Josh Alexander about companies Yahoo! should purchase, please do… I’ll wait. Ok – now that you’re back – isn’t this guy funny? It isn’t too often I read an article about tech where I learn things and also laugh out loud.
