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.

Do Away With Voice Mail?

November 12, 2013

I was reading my Sunday newspaper a few weeks ago, when I came across an article claiming companies should do away with internal voice mail. I was flabbergasted.  I couldn’t believe it. I read the article and I saw the author’s reasons; voicemail takes too long, we have easier and better ways to communicate nowadays, it’s a pain.

NFV and SDN: Ignore at your own risk

November 5, 2013

It’s hard to believe it now, but at one time, VoIP was a hard sell in this industry. At pivotal moments in this market, telcos have faced the challenge of having to do something to react to changing user needs and habits, but they have hesitated to believe that heir-apparent technologies were the way to go. We are at one of those crossroads again. Just as VoIP was once doubted yet imminent, NFV and SDN sit poised to become hugely important in the telco space.

At Gitex, MEA's Premier Telecoms Event, Lessons in Luxury Selling

October 29, 2013

The Gitex tradeshow in Dubai is a great place to see a lifestyle-over-cost approach to selling telecom services. The show, which I recently attended for the second time, has a Mobile World Congress feel to it with a frenzy of meetings that would normally take weeks to conduct. There are two main differences, however, between Gitex and the West’s premier mobile event. First, the attendees at Gitex come from throughout the Middle East and across Africa.

Despite Carriers' Views, OTT is Not the Enemy

October 22, 2013

Last week an interviewer asked me, “How will the carriers combat OTT?” Well, from a certain point of view, OTT apps aren’t the enemy. They drive traffic on the data part of the mobile network, which drives revenue for the mobile network operators. It’s the pricing plans that are the enemy.

However, I think the root of the question was really about OTT players taking revenue away from carriers.

The SBC evolution toward media

October 15, 2013

As networks grow, session border controllers need to do more in order to keep pace. There’s no reason why SBCs shouldn’t incorporate the functions of a media server. SBCs came into their own as edge devices that could insulate one IP network from another. This applies to both enterprise IP-IP networks, service provider IP-IP networks, and enterprise/service provider IP networks. 

The PSTN is dead. Or is it?

October 8, 2013

The PSTN is dead. We all know this because all we hear about is IP and government-backed PSTN sunset requirements. Right? If that is actually the case, then when Dialogic sells a softswitch, why do we also still usually sell media gateways as part of the overall solution?

Location Insight Could Yield Different Kinds of Revenue

October 1, 2013

A few weeks ago, I first heard the term "Location Insight Services," or LIS, from Telco 2.0’s recent research. LIS basically take location-based services (LBS) to the next step. Location-based services involve tracking your cell phone, for instance (with your consent). Mobile service providers can determine your whereabouts and know where your phone is because of the tower it’s connected to or because of GPS.

The Interworking Protocols Mobile Users Don't Know They Need

September 24, 2013

The proliferation of LTE networks is making life pretty sweet – and fast – for mobile users right now. Consumers are spending more time watching videos from their smartphones and tablets, all the while never knowing the complex signaling protocols that are giving them a seamless experience, regardless of whether they’re roaming in and out of 3G and 4G territory. LTE’s signaling protocol, Diameter, makes the interactions with other networks possible, and it might be the most important enabler mobile consumers never heard of.

Let’s say you walk into a Starbucks.

Where is the 4G?

September 16, 2013

Last week, I was in the U.K. and I had a bit of a frustrating experience. I have 4G service in the U.S., and I own a 4G-capable smartphone. I know there is 4G service in the U.K., yet I couldn’t get the service working.

How the Rise of LTE is (Quietly) Changing User Behavior

September 10, 2013

One of the big, glittering bright spots in the mobile industry right now is shining straight out from LTE. Global deployments are ramping up – there are about 200 commercial LTE networks right now – and subscribers are signing on in huge numbers. Rapid growth always carries consequences, but some of the most significant repercussions are those that users barely notice, even though they are directly affected by them. Because of its speed, LTE delivers an attractive mobile on-ramp to the Internet, which is changing the way smartphone and tablet owners use their devices.
