Why Test Automation is a Strategic Enabler for 4G Services

If you are reading this you are likely to be someone from mobile in telecoms and are likely to be involved with product management, operations or testing and we encourage you to read on.

Both prelaunch security verifications and measurements of quality of experience are essential to assure future operator revenue

European mobile operators are currently preparing and verifying their core and radio networks for the introduction of voice and video calls and other innovative services over LTE.

As the telecommunication services evolve with the subscribers’ applications in today’s networks, there is a growing disconnection between the perception of quality of the services the operators provide, and the actual quality perceived by their customers. As Ericsson points out on a recent paper, “The quality of user experience has always been important for operators. However, with the rise of mobile-broadband and smartphone usage over the past few years, the meaning of user experience has changed dramatically”. The issue has to do with the lack of visibility that the operator has beyond their network devices in the Radio Access Network (RAN) and the Core Network, where they cannot measure the actual connectivity the customers have on their ends. Measuring the cells power or the aggregated throughput in the core, is not the same as knowing that an important customer has a weak coverage, or his application is timing-out because of high latency in the communication.
