Leading European Telco Operator
A leading European telco operator wanted to improve and economize testing in the packet core. The company sought to automate the allocation of different Quality of Service (QoS) settings defined in the Policy and Charging Rules Function (PCRF) Automatic testing would be conducted after every software upgrade or network change, to verify the functionality of all 20 different QoS profiles, which include functions like speed step-down or child protection.
PCRF regression testing took about four days to manually run 20 test cases because of its complexity. First, the correct QoS profile had to be assigned to the customer under test. Once that was successfully completed, a packet session was established from the real customer mobile using customer-branded phones to ensure that the service was working for the end customer using a mobile phone for the specific operator. All of this had to be done within the context of the combination of end customer-specific mobile control with up/downlink speed, web service verification, and control of the PCRF-related data provisioning.
The current approach required 32 working-person hours. Such a manually intensive process limited engineers’ time for other testing, which increased a risk of inadequate QoS. Furthermore, the demand for PCRF testing has already grown in recent years, a trend that promises to continue. The client recognized that a manual testing protocol would be difficult to scale as testing needs increased.
Automated PCRF Testing
Since manual testing wasn’t going to cut it, the company began to consider their options for automaThe clients recognized that a manual protocol wouldn’t provide the efficiency and scalability necessary to keep up with growing PCRF testing requirements.
They needed an automated option that addressed QoS setting provisioning, along with end-to-end (E2E) uplink/downlink and web service verification.ted testing. While many of the solutions available on the market right now offer simulated testing or testing on rooted devices, SEGRON was able to orchestrate automated testing on out-of-the-box devices to the tune of hundreds of test cases per user per day.
Using SEGRON ATF (Automated Test Framework), the client was able to establish a robust testing environment, automating 500 complex Priority-1 test cases to ensure efficient and high-quality service verification. The best part?
Using its unique Automated Testing Framework (ATF), SEGRON set up a robust testing environment and automated all 20 complex Priority-1 test cases to verify the PS service offered to customers.
Now, executing all 20 tests takes only 30 minutes, and tests can be conducted quickly even after small changes to the network
This practical, affordable solution reduced testing time by 98.5%
Furthermore, results were more reliable than those gleaned from manual testing, and simple reporting tools made it easy for engineers to gather and interpret test results. The versatility of SEGRON ATF also meant that tests could be added or modified as use case priorities evolved over time.
The time and effort saved by the implementation of SEGRON ATF translated into an immediate return on investment. The client could also reallocate resources to other forms of testing and better scale alongside changing market conditions. And most importantly, automated testing contributed to better overall network quality, a critical factor for maintaining customer satisfaction and increasing profitability.
