Way back in the day, if you were on the go and needed to make a phone call, you kept your eyes peeled for the nearest payphone. You would drop in your coins and the operator would connect you to your desired call recipient. After the time you paid for had run out, a live operator would butt in and let you know that in order to extend your call you needed to add more money. Today, the idea of something like this happening during a VoLTE call seems a little bit absurd—but in point of fact it represents a need that all telco operators still grapple with: real-time provisioning of services based on what the user has actually paid for.

How To: Mobility Management

In the US right now, Verizon and T-Mobile are battling it out for who can provide the most extensive LTE coverage. And as of OpenSignal’s 2018 report, the two were in a statistical tie—each was able to provide an LTE signal 93.7% of the time. These are historic highs for the companies, and objectively impressive numbers, but that still means that they’re failing to provide an LTE signal fully one-twentieth of the time. As such, SRVCC (Single Radio Voice Call Continuity) would still be critical to providing high quality of service (QoS). Why? Because right now it’s the standard solution for ensuring mid-call handovers from all-IP LTE networks to circuit-switched call bearer 2G/3G networks.

Backward compatibility is a noble goal for any communication system. For telecom networks in particular, it's an important part of providing seamless coverage across legacy platforms, which means you can keep customers happy without forcing them to upgrade their service constantly. By placing an emphasis on service in this way, you can help protect revenue over time. That said, ensuring legacy integration can often provide challenges for operators.

We’ve talked a little bit already at this blog about how automated testing is becoming a virtual necessity for telco operators. As increasing device fragmentation and the proliferation of different protocols continue to inflate the number of use cases that require testing, human testers are struggling to keep up. But, if you’re reading this, you probably know all that. More than that, you’re probably almost ready to take the plunge and seriously consider an automated testing solution for your business. The question at this point is, how do you choose the right tool?

5G Is Coming: How Will Your Device Testing Keep Pace?

In June of last year, The 3rd Generation Partnership Project set the official standards for standalone 5G, effectively paving the way for the era of true 5G functionality. It might be a little bit of an exaggeration to say that we’re now experiencing a race to create usable 5G networks and devices among the wireless carriers and device manufacturers of the world (Apple, for instance, has been forthright about its decision to wait until 2020 to roll out its first 5G-enabled smartphone), but the floodgates are certainly beginning to open—and carriers like Verizon and AT&T are already performing a limited rollout of 5G home and mobile networks. In Europe, a leading operator in the 5G space has already announced its support for the OPPO Reno 5G.

Is Manual Device Testing Hurting Customer Experience?

In 2012, an OpenSignal study found that there were about 4,000 different Android device models on the market. Within a couple of years, that number had risen to 12,000, and it’s likely only gone up since then. As a device tester, you already know that there’s considerable diversity among your customers, and that their needs are going to vary on a case-by-case basis—but who knew there was so much diversity just in the devices themselves?
