Metaswitch Powers the Internet of Talk

VoIP (Voice over Internet Protocol) VoLTE mobile applications Mobile Infrastructure IoTalk

If you’ve been following our series here, you’ll know what we mean by the “Internet of Talk.” With so much energy dedicated to technology for connecting billions of devices in the Internet of Things (IoT), it’s important not to forget that people want to connect and talk to each other too. Even though messaging dominates how we communicate and traditional voice and SMS usage is shrinking, the richness of human interaction goes beyond emojis, acronyms and shortened, phonetic spellings.  AIBU? ;-) We want to use our voices and we need mobile networks that not only guarantee a decent experience but also make it even better. The Internet of Talk is about the infrastructure and services that enhance communication between people, not just things, and Metaswitch is at the heart of it.

The Mobile Data Network Finds Its Voice

Before we all rush to meet a 5G future of network slicing, massive machine communications and autonomous vehicles, let’s take a moment to appreciate what we have with 4G. After all, Long Term Evolution (LTE) is one of the wireless industry’s greatest success stories. Designed for mobile data communications, the packet-switched, all-IP technology has allowed us to share and access information on the move like never before, contributing to the 8.5 exabytes of mobile data traffic that’s generated around the world every month. As of late 2016, LTE connected almost one in four mobile subscribers globally and outpaced 3G subscriber growth, making it the fastest growing mobile technology, according to the Global mobile Suppliers Association (GSA) . The only blemish in this rosy LTE picture is voice services. As we all know, delivering Voice over LTE (VoLTE) services proved to be more difficult than anyone anticipated. But now, recent market momentum shows that operators are ready to supercharge VoLTE.

The Enhanced Voice Services Codec - Improving audio for the Internet of Talk

OK, I’ll be the first to admit it -- I have a somewhat unhealthy fascination with codecs. While I’ve always been one for a thrilling tale of analog to digital quantization, my head pretty much exploded when I first read about the mechanics behind G.729, aka CELP: Code-excited linear prediction. I mean, seriously, how cool is that name? Even now, when I read it, my mind is awash with the prospect of enthusiastic bits of data foretelling their future (albeit conservative) path. I was always so happy for them. And, of course, that wasn’t the end of CELPs story. These bits quickly became math whizzes (Algebraic/ACELP), which then became quicker (Low Delay/LD-CELP) but then formed some sort of strange growth (conjugate-structure/CS-ACELP), which I admit was a little sad. What I learned about CELP, circa 1995, was from technical “books” -- typically heavy objects costing in the region of one million dollars, in today’s money.1

IoT - The Internet of Talk

Twelve gazillion connected devices. I think that’s the last official count for the number of “Internet of Things” endpoints mobile network operators are expected to handle, in the coming years. While a few of those will include some complex machine-to-person or even person-to-person interaction, the majority will be to and from dumb sensors over low-power wireless with a constrained P2P protocols. Now I might be going out on a limb here, but I think that we are paying far too much attention to these “Things.” OK – together, they might enable clever computing platforms or even AI to reach some smart conclusions or predictions, but, individually, let’s not forget that they are still just small inanimate objects of little intelligence. It’s easy to ignore people in favor of the docile data processing devices that populate our homes, cars and bodies. Indeed, I’d go as far as saying it’s fashionable. Some might say we brought it all on ourselves, with our increasingly prevalent propensity to communicate in perfunctory ways, but there’s a revolution brewing.

5G Network Slicing - Separating the Internet of Things from the Internet of Talk

You know when you hear something relatively obscure for the first time and then come across it again soon after. And again soon after that. I had one of those moments about a year ago when I was first introduced to the concept of 5G network slicing. Now, I know what you’re thinking: “Come on, Dredgie. It was new and someone was pushing it in the media, which you finally noticed after waking up from one of your numerous, protracted, marketing fogs.” Well, not really -- but I did use that exact excuse for missing my wedding anniversary, so I won’t discount the possibility outright. No. I think it was the Baader-Meinhof1 phenomenon in action.

Cloud Native On Top Down Under

As network functions virtualization (NFV) matures, the conversation is rightly moving to the importance of “cloud native” communications software. At Metaswitch, we’ve understood since the earliest days of NFV that virtual network functions (VNFs) need to be designed for the cloud from scratch so that service providers can realize the full benefits of network virtualization.  Visionary operators like 2degrees realize this, too.

Fixed-Line Transformation NFV (Network Functions Virtualization) Mobile Infrastructure Industry Trends

Metaswitch has gained a wealth of NFV experience by helping customers take our virtual network functions (VNFs) from proof of concept to lab trials to production networks. Along the way we have learned a lot about what works and what doesn’t and how to overcome unexpected issues as they arise.

Want to know what happens to the video footage left on the cutting room floor, after the professionals have taken all they need... or can handle? Well, we sweep it up and recycle it - naturally! Check out this short outtake reel from a recent Intel interview and learn how Metaswitch is pioneering cloud-native virtualized network functions to deliver on the promise of 5G and IoT. The sentiment is sincere and the proposition genuine but the performance leaves a lot to be desired. Don't say I didn't warn you!

The IP Multimedia Subsystem Comes of Age

They grow up so fast, don't they? It seems only yesterday that the 3GPP gave birth to the IP Multimedia Subsystem and now we are getting ready to celebrate its Sweet Sixteen and turn it loose on the world.

Of course, way back in (Release) 2000 we didn’t even have a name for it, so we called it “All IP”. Supporting its newly minted acronym, the first IMS specifications were frozen in March 2002 under TS22.228 and promised a world where decoupled signaling and media services were delivered from highly decomposed network functions with well-defined (predominantly SIP-based) reference interfaces, providing modular scalability while eliminating the classic application stovepipes. Back then, each and every stovepipe was dominated by a large vendor who dictated every component in the service chain, often compelling network operators to employ expensive, sub-par, components while frequently forcing them to deploy more than one variant of the same product. Our newborn was going to change the status quo. Take the telecom world by storm.
