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.

The Pros and Cons of Keyword Based Testing

Let’s say you have a small system whose functionality you want to test, and you determine that there are five distinct use cases that require verification. As a technically-adept test engineer with a fair amount of programming skill, what do you do? In all likelihood, you simply script up each test case individually, so that for each use case there’s a unique piece of code that needs to run in order to make sure that everything is working smoothly. This makes sense, and as test automation has become more common (in some sectors, anyway), we've seen a lot more people doing just that. For a limited number of test cases, this is probably the smart thing to do. But what happens when it’s not half a dozen use cases that require scripting, but hundreds or thousands?

How To: Verifying eCall Service

Oct 29, 2019 3:00:00 PM / by Michael Sedláček posted in 24/7 Regression, Automation ROI

As the Internet of Things (IoT) grows and expands, the number of different elements that will have to consistently connect to any given network is expanding with it. Of course, some of these elements are more impactful than others. For instance, as of March of 2018, an EU directive requires that all new passenger cars be equipped with an EU eCall system. Because every second can be vital after a serious accident, it’s essential that in case of an accident the eCall device transmits emergency data to the nearest emergency center (PSAP, or “public safety answering point”) and/or trigger an emergency call. This means that in every EU country your network must automatically relay relevant information (e.g. vehicle type, direction, number of passengers, engine type, VIN, GPS coordinates, etc.) from the eCall modem to the correct emergency center in case the driver is too incapacitated to speak.

Can Robots Speed Up End-to-End Testing?

Oct 8, 2019 3:00:00 PM / by Jari Nurminen posted in Automation ROI, End-to-End Testing

End-to-end testing: for many telco operators it’s the holy grail of service verification, but it can also be a slow, laborious process that adversely impacts time to market. Even if you’ve managed to automate your relevant equipment and collect success and failure data from the relevant end-points, you might still find yourself in a position where hard-to-read data and hard-to-program use cases stop your end-to-end tests from running as quickly as you would like. When this happens, you’re in the uncomfortable position of either sacrificing high levels of test coverage by cutting the test off early, or delaying your network migration or device rollout to accommodate slow testing.

As recently as a few years ago, the idea of a smart home—in which all of your appliances and other sensors around your home are networked together digitally—still seemed more like science fiction than a fact of life. And yet, today you can walk into many new homes and use your smartphone to control the temperature and the lighting, you can preheat the oven remotely, and you can get alerts to your mobile device if your smoke detector or burglar alarm goes off. It’s the type of home that technologists have dreamed of for decades.

Outsourced vs. In-house: Which Testing Method is Better for Telecoms?

Sep 17, 2019 9:00:00 AM / by Thomas Groissenberger posted in Automation, Automation ROI

0 Comments

At some point in their growth and development, most businesses regardless of industry eventually reach a point where they realize they can’t do it all themselves. Either they need help marketing their product, or some of their more tedious HR tasks could be outsourced, or their testing operations could be made more efficient by partnering with an outside agency. Some companies outgrow this stage and ultimately reclaim their ability to do things in-house, but others continue to grow with their partnerships in tact. Neither approach is necessarily better than the other—but they both present distinct pros and cons.

3 Examples of End-to-End Telecom Testing in Action

We talk a lot on this blog about end-to-end testing, and we don’t plan to change that fact any time soon. Why? Because end-to-end still represents the only testing methodology that puts the needs of end-users at the center of the testing process—and end-user experience is only becoming more important in the ever-changing telecom domain. So, naturally we want to give our readers the tools and information they need to outline end-to-end tests within their networks in order to maintain a high quality of service. That’s why today we’re taking a deeper look at some specific instances of end-to-end testing, in order to provide a more concrete idea of what this methodology looks like in practice.

Let’s imagine that you’re a trendy new startup. You’ve got a new widget that lots of people are downloading that helps that track their runs, or manage their time more effectively, or connect with other members of their community. Sure, there are the usual set of information security concerns, and you have plenty of functionality to build out over time, but the occasional bug or service outage isn’t going to be the end of the world. While high quality testing is still mission critical, it might not feel like a life and death situation.

How Can Telco Operators Speed Up Conformance Testing?

Sep 5, 2019 3:00:00 PM / by Michael Sedláček posted in Time to Market, Automation ROI, 5G

0 Comments

When technology changes and evolves—as it does almost constantly—in the telecom domain, it typically takes standard-setting bodies like 3GPP six months to a year to establish a new set of test cases for conformance testers. Once those test cases come out, there’s a flurry of activity while operators, device manufacturers, OEMs, and others attempt to verify compliance and interoperability with new and existing standards. The fact that it takes 3GPP a fairly long stretch of time does very little to lessen the time pressure that testers usually face when it comes to performing each new round of service verification.

The modern cycle of updates for telecom networks continues to speed up, and telco operators need to do the same in order to keep pace with the market. For some of you, this may be leading you to consider test automation for verifying service on your network. Sure, there’s plenty of content out there about automated testing, and some of if even pertains to the specific challenges that your company has—but it’s still more than a little bit daunting. You know you need a framework that can automatically test, for instance, audio quality for VoLTE service across a suite of modern and legacy devices, but how do you get started?
