DEVICE & FIRMWARE PRE-RELEASE TESTING

SmartphonesMobile

Challenge

Solution

Keeping pace with device and firmware evolution had become a challenge for the device testing team of a European Tier-1 mobile network operator. More than 60 devices and 200 firmware versions per year needed to be tested and this amount was expected to grow further. Device manufacturers have begun “outsourcing” testing of new firmware and devices to the MNO.
SEGRON installed the intelligent Device Automation (iDA) solution supporting the ATF device control. The iDA uses artificial intelligence technology to integrate new and pre-released devices, as well as firmware versions, within minutes into the ATF to enable seamless testing. Today, our customer simply connects the new devices to the ATF/iDA, and the device learning process is initiated automatically. In less than 15 minutes, existing test cases can be executed using new or even pre-released devices.

Benefits

Day 1 Availability of New Devices for Automated Testing

Device testing and service verification using latest smartphones and firmware versions is key to optimal QoE and customer satisfaction. Legacy test automation tools fail to keep pace with device evolution or require time consuming maintenance. The advanced capabilities of the ATF, in combination with iDA, enable day 1 availability of newest devices for test automation and decrease test duration time significantly.

Accelerated Time-to-Market While Ensuring Optimal QoE

Time-to-market is super critical when it come to launching new iOS and Android-based flagship devices. Accelerating this process by using the ATF and iDA without any compromises on QoS and QoE directly results in a competitive advantage for our client.

Global Service Enabler

INTERNATIONAL ROAMING TESTING

Challenge

Solution

A Tier-1 EU mobile operator approached us to verify correct functionality of existing and newly introduced roaming services for different network domains. The verification needed to be done on regular basis, including hosted mobile virtual network operators (MVNOs) and services such as end-to-end IPX connectivity, data roaming, voice services (VoLTE), diameter and GTP roaming solutions. A strong focus has been put on VoLTE and 5G roaming testing.
SEGRON’s Global Service Enabler (GSE) uses real smartphones in multiple locations globally for automated verification of MNO/MVNO services in all network domains. SIM cards were provided by the customer and inserted into the central SIM arrays hosted by SEGRON. IREG test experts on the client and SEGRON side defined test campaign and locations and enabled automated service verification with regular reporting and immediate alarming in case of fault detection.

Benefits

Increased Productivity and a Future Proof Solution

Productivity was significantly improved. In the past, manual testing in combination with modem based legacy tools lead to delays and uncertain results. Smartphone based verification of services like VoLTE, 5G and OTT app QoE is the future proof way to have maximum confidence in customer satisfaction and optimal QoE in domestic and roaming scenarios.

Accelerated Time-to-Market and Cost Reduction

Manual testing can be reduced to a minimum and new services are verified quickly and with latest smartphone technology in roaming scenarios. This results in accelerated time-to-market and significant resource and cost reduction.

Challenge

A Tier-1 mobile operator needed to ensure the correct functionality of very complex radio interworking tests with a variety of different smartphones, including Layer3 analysis, inter-, intra system handover, SRVCC, 5G dual connectivity verification in a laboratory environment.

The manual execution of 50 complex test cases took several days to execute as precise analysis was necessary.

Solution

SEGRON installed an on-premises ATF instance with a custom RAN verification suite including automated attenuator control, shielded boxes, and Layer3 radio protocol analysis.

An automated environment Health Check Suite was deployed to monitor the RAN availability and environment status including automated notification in case of problem detection.

Benefit

Increased productivity

Even though there were only 50 test cases, the environment preparation and manual post-testing analysis was a big pain point for the customer.
After deployment of the ATF, the automated execution of these 50 test cases, including the precise analysis, have been completed within less than 3 hours.

Improved Efficiency & Accuracy

Efficient, automated active testing solutions using real devices in an early stage of the product lifecycle (laboratories) is important to ensure optimal customer experience in production networks.

Challenge

A European mobile operator had a big issue with testing a wide range of device and firmware versions, which needed to be released every month.

In total, he faced around 150 firmware versions per year per each device, which need to be verified on regular basis. This resulted in a huge testing effort, especially considering the quick evolution on the smartphone and device market.

Solution

SEGRON installed the intelligent Device Automation (iDA) solution on-premises while leveraging the ATF. The iDA uses artificial intelligence technology to learn how to control the connected devices within a matter of minutes to enable seamless testing for the most common device manufacturers.

Now, our customer simply connects the device with the iDA to execute the device learning process, and their entire device and firmware testing suite can be performed with the ATF.

Benefit

Improved Detection of Phone Issues

Device and network issues which happen with only certain devices can be identified more quickly. This results in a massive decrease of identified phone issues in the operator’s live network.

Decreased Time-to-Market

Pre-released devices, new device and firmware versions can now be released to the market much more quickly. The testing of firmware versions was normally taking weeks; now it can be completed within days, including the administrative tasks.

Global Service Enabler

G_bianco

Challenge

A Tier-1 EU mobile operator needed to verify the availability and correct functionality of all deployed and newly introduced roaming services for the different network domains.

This included the portfolio of the mobile network operator (MNO) itself, as well as all the hosted mobile virtual network operators (MVNOs) and included services such as end-to-end IPX connectivity, data roaming, voice connections and CLI, diameter and GTP roaming solutions.

Solution

SEGRON’s Global Service Enabler (GSE) uses real smartphones in multiple locations globally for the automated verification of the offered MNO/MVNO services in all network domains.

SIM cards were provided by the customer and inserted into the central SIM array hosted by SEGRON after agreement of the different test campaigns. SEGRON started the automated service verification and provided the related reports to the customer.

Benefit

Increased productivity

Productivity was significantly improved. In the past, manual testing and all the necessary preparations were very time consuming.

Instead of creating alignment with every roaming partner, now our customers get regular reports and results of the performed test automatically for all of their selected roaming partners.

Reduced Customer Issues & faster deployment of new services

Customer issues can be significantly reduced because problems are identified and resolved before customers face them on the live network. Further new roaming services can be introduced much faster compared to the old manual approach.
