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 Mobile VAS Ecosystem on a Page

June 19, 2012

Last month, I wrote about the Mobile VAS Ecosystem and I was asked a few questions about this topic. I figured the best way to answer these questions was to show this slide and then explain the slide.

First of all, Value Added Services (VAS), in the context of what I’ve been writing about for a long time, are services that consumers would be willing to pay extra for, and would be network-based services.

Backhaul Optimization Technology Even in the Ethernet Backhaul World

June 12, 2012

Last week I talked about mobile backhaul and optimization of the backhaul playing a key role going forward. Another item to consider with backhaul is the movement of backhaul from TDM to Ethernet. There is significant movement in this space going on right now, with Ethernet growing and TDM declining as you would expect. And this trend will clearly keep going as the wireless industry moves to 4G/LTE.

Additionally, this large market and shift to Ethernet backhaul has attracted the attention of the Metro Ethernet Forum (MEF), who have announced Carrier Ethernet 2.0 and their “Mobile Backhaul Initiative.” Essentially, Carrier Ethernet 2.0 enables multiple classes of service over interconnected networks.

The Case for Backhaul Optimization Technology

June 5, 2012

We all understand that mobile subscriptions are growing, and that pretty soon there will be more connected mobile devices on the planet than there are people. And I’ve written in this space before about the Cisco Visual Networking Index, which gives interesting information about past and future mobile data use. One interesting tidbit that came from the last report from February 2012 is that although smartphones represent only 12% of total global handsets today, they account for over 82% of global handset traffic. 

SBCs: A New Necessity for Service Providers and Enterprises, Part 3

May 29, 2012

Three weeks ago, I wrote about the benefits that Session Border Controllers (SBCs) can have for both service providers and enterprises. This week, I’d like to talk about some new applications that SBCs can help enable.

Traditionally, there have been  two general "use cases" for an SBC:

  • As an "interconnect" device located at the "peering" border, or Network-to-Network Interface (NNI), between interconnecting carrier network
  • As an "access" device, in which the SBC protects the edge of a service provider network and provides SIP trunking to an enterprise. 

The Mobile VAS Ecosystem

May 22, 2012

Last week in Thailand, Dialogic held an event for our APAC customers. Although Dialogic is evolving to provide more and more service provider infrastructure products like Softswitches, SBCs and mobile backhaul optimization solutions, the technology enabling part of our business continues to remain vital and important. As such, it was natural for us to hold an “Innovation Panel” where we got a mix of Value Added Service (VAS) solution providers, Dialogic GMs and an analyst to discuss the VAS ecosystem. APAC has always been at the forefront of innovative VAS applications, being the birthplace (on Dialogic enabling technology of course!) of CRBT, Mobile Radio, Voice SMS and countless other VAS applications. 

Real, Live Video Conferencing of Smart Devices on LTE, WiFi and 3G

May 15, 2012

Last week at CTIA, during a scheduled press conference on May 8th at 11:00AM, Dialogic demonstrated the future of video conferencing by tying together collaborative input including live people and video streams, on various devices, on various advanced networks, in a single video conference.

What is so special about this? Well, it’s believed to be the first public demonstration of its kind.

SBCs: A New Necessity for Service Providers and Enterprises, Part 2

May 8, 2012

In my blog from last week, I talked about today’s communications network environment and how Session Border Controllers (SBCs) are critical when it comes to interconnecting TDM and IP networks. This week, I’d like to talk about the specific benefits that SBCs offer service providers and enterprises.

Basically, there are many things that an SBC can do well.

Session Border Controllers: A New Necessity for Service Providers and Enterprises, Part 1

May 1, 2012

Today’s communications networking environment is rapidly changing and very complex. IP has become the new transport methodology for delivering voice and video services, while converged applications are growing quickly and video is expanding at exponential rates. More and more IP networks are being installed and used today as core networks, which until recently were considered "adjunct" networks connected to "core" TDM networks through gateways.

The Impact of $100 Smartphones

April 24, 2012

In last week’s blog I explored the surge in mobile data traffic. And when economical smartphones enter the scene, most likely throughout the course of 2012, the surge will simply continue. The IDC Asia “Confronting Telecom’s Network Challenge” report says, “Consumer behavior in these markets will be similar to that in mature markets. Consumers in mature markets have demonstrated an addictive nature to mobile applications…”

The Wireless Data Challenge

April 17, 2012

We’ve all read about the surge in wireless data traffic which has been happening for the past few years and is expected to continue going forward. You probably know people who own a smartphone and an iPad and a laptop and use all of those devices. Or you know people who are seemingly glued to their iPhones all day. So in your little world, you get it.
