Whether it’s rolling out a new 5G network, a new technology overlay, or expanding your network coverage footprint, accurately assessing pre- launch performance is critical. Only by testing and optimizing the network from your subscribers’ perspective can you be confident that the network is going to deliver the promised 5G user experience. This is where site verification comes in. What is site verification? Site verification involves validating that new 5G sites and clusters provide the intended coverage and that all voice and data services are working as expected before subscribers are allowed to access the network. Within a mobile operator’s organization, the responsibility for initial site tuning and verification sits with the network deployment team. The challenge is one of complexity and scale. For every new site that is built, the network deployment team needs to ensure it is well integrated with its neighbors in the existing network and performing optimally. In the case of most 5G network roll-outs, this will involve many thousands of sites each requiring comprehensive drive testing. A time- consuming and expensive process, where finding efficiencies is critical. The network deployment team has responsibility for not only validating, troubleshooting and optimizing the deployment, but they also need to be able to provide reports to the business on the status of the 5G network rollout. With operators’ CAPEX and OPEX under pressure and scrutiny, the network deployment team is on the front line to ensure the rollout is completed quickly, cost- effectively and accurately.

For operators that are racing to deploy new 5G sites, while continuing to optimize and expand existing network coverage, this new network testing approach is a game-changer. Nokia

TEMS™ USE CASES

User experience testing Solution: TEMS Investigation, TEMS Pocket, TEMS Paragon, TEMS Sense Today’s networks need to successfully support a vast array of services, everything from simple text messages to services characterized by demanding requirements, ranging from high bandwidth 4K video streaming to very low latency e-gaming. User experience (UX) testing is critical if you are to ensure your network is delivering the quality expected by customers for any of the apps or services they are using. By combining machine learning algorithms with sophisticated traffic modeling, UX testing enables you to understand the user experience for all these applications and services. What is UX testing? UX testing enables you to innovatively combine various generic testing techniques, sophisticated real live service traffic pattern emulations and machine learning (ML) algorithms to fully test not only your network, but also the user experience of any native or OTT applications and services running over them. This means you can test the user experience of high bandwidth, low latency 5G services such as the e-gaming genre of First-Person Shooter (FPS) games, OTT voice applications including WhatsApp, and video-on- demand streaming services like Netflix. Thanks to the variety and volume of OTT apps and the ever-expanding range of devices, it’s simply not practical or financially viable to test every device, every OTT app and every interactive service. Instead, by testing the network against the key parameters of the most demanding and/or most commonly used OTT application/service, you can have confidence that you are not only delivering a network capable of supporting less intensive and/ or less common OTT apps and services, but making user experiences promises, safe in the knowledge that your network will deliver.

The benefits of UX testing with TEMS Our user experience testing portfolio enables you to understand, and improve, the user experience for all applications and services. It includes solutions for native and OTT voice services, OTT applications, and interactive services such as mobile gaming. • Ensure 5G user experience by accurately measuring quality of experience for all native and OTT applications and services. • Benefit from network-centric voice quality testing with sQLEAR, the world’s first machine learning-based standard for 5G VoNR voice quality testing approved by ITU and that provides a device, and device settings, agnostic, view of true voice quality without the need to test every individual device. • Ensure subscriber QoE across all apps with our generic testing approach that is highly correlated to real-world testing for a more practical and cost-effective solution. • Test any standard OTT application without the requirement for customized OTT applications to be able to successfully test.

The challenge with testing OTT apps today is that parameters change with every release update. How to login or the layout and behavior of the app can change without any notice, and can differ between devices, countries and even networks.

Large events, such as music festivals, football matches and special events at large indoor arenas will typically see the mobile network extremely stressed. A high volume of people, many of whom at any one time will be uploading content to social media, using OTT apps to communicate with friends, or streaming live content will place immense strain on the network. Verifying, optimizing and troubleshooting the mobile network in these types of environments is important, but resources are stretched and dispatching engineers to every large event is tricky. You need to be able to mobilize your non-technical staff in support. What is special event monitoring? Special event monitoring involves testing the quality of the network and gathering valuable data at large-scale special events where networks are typically extremely stressed. Skilled engineering resources are finite and the demands on their skillset mean they are already being pulled in many directions. To address this, special event monitoring can be supported in the field by non- technical staff, with specialist engineers remotely managing testing centrally from HQ. For this approach to be successful requires a highly portable network testing solution that can be easily taken to venues, and, crucially, it must work without requiring any engineering expertise to be on hand when out in the field. The solution is to equip non-technical staff who are already attending an event with a portable network testing solution in the form factor of a phone that they can simply pop in their bag or pocket, and do nothing more, other than enjoy the event. While colleagues are at the event, engineers can remotely control the test phones, deciding what scripts should be executed and generating real- time data analytics, enabling them to verify and troubleshoot the mobile network without ever leaving the office.

You cannot expect general staff to role-play being network engineers. Effective special event monitoring requires them to be able to simply take a device, pop it in their bag, travel to the event, and then do nothing more.
