Roaming Quality Testing

Roaming assurance for excellent experience

Roaming is undeniably complex due to the interworking technologies and interconnect partners.

Mobileum’s Roaming Quality Testing uses the world’s largest end-to-end active testing platform GlobalRoamer®, covering more than 98% of the world and supporting 2G, 3G, LTE, CSFB, VoLTE, IoT, 5G, and Emergency Services. Real mobile traffic can be generated and tested anywhere, anytime, by virtualizing any SIM to any location in the globe, using our SIM card pool from 500+ MVOs. Our extensive amount of test cases allows you to measure and improve QoS and QoE and identify service outages through real-time reporting and alarming. The use cases:

Ensure user experience anywhere, anytime…

Global tourism is at an all-time high, and travelers expect their communication services to work the same when they are roaming as they do when they are at home. The challenge to ensuring a consistent experience for subscribers means that today’s communication service provider (CSP) needs to be able to test services such as highspeed access and VoLTE for inbound and outbound users. These services also need to be validated at the initial setup of roaming agreements.

The world's leading roaming testing footprint

GlobalRoamer® is the world’s largest end-to-end active testing platform, covering more than 98% of the world and supporting 2G, 3G, LTE, CSFB, VoLTE, IoT, 5G and Emergency Services. Real mobile international traffic can be generated and tested anywhere, anytime, providing a true picture of network and services performance for roaming scenarios.

By reaching thousands of VLRs around the world, Mobileum’s GlobalRoamer® solution enables CSPs to test international roaming agreements. CSPs are enabled to cross-check global partnerships, in addition to their customer’s roaming experience.

The impact is widespread, benefiting not only the subscriber’s service experience but also the CSP, which can now speed up roaming agreements and troubleshoot any problem more quickly.

Global IoT connectivity

With GlobalRoamer® you can test end-to-end IoT QoS worldwide on 150+ locations in 100+ countries over more than 210+ networks. It is GSMA compliant and supports 2G, 3G, LTE, NB-IoT & LTE-M and 5G, addressing the 3 pain-points of IoT:

Mobileum’s Connected Car Testing use case monitors eCall, IoT Telemetrics, eSIM remote provisioning, and business applications availability. Important KPIs for mobile operators and automotive vendors are:

Monitor multiple service scenarios

Compared with other available solutions, Mobileum’s GlobalRoamer® extends well beyond the basic test call generator (TCG) capabilities. By utilizing its inherent auto-discovery to identify thousands of visitor location register (VLR) robots, GlobalRoamer® can perform extensive testing in search of malicious threats or inadvertent misconfigurations through the signaling layer, thus increasing the fault detection probabilities. The probability of threat detection in any interface is much improved due to the vast number of requests the system can generate. GlobalRoamer® enables service providers to identify problems in voice and data services, as well as in processes such as rating configuration, provisioning, and network consistency.

IREG and International Roaming Tester

The roaming subscriber is associated with both a host network and a roaming partner network. To assure subscriber service quality when launching services with new roaming partners for 2G/3G/LTE/VoLTE services, Mobileum GlobalRoamer® enables CSPs to test the International Roaming Expert Group (IREG) uses cases with new partner networks. Mobileum’s Roaming CEM expertise, coupled with its predictive intelligence capability, makes Mobileum the vendor of choice when it comes time to identify QoS compliant roaming partners.

Support for complete IREG testing

The IREG testing is part of the normal process of launching Roaming between two operators. International Roaming Expert Group (IREG), testing is important to benchmark the capabilities that two service providers must support before roaming agreements can be put into place. GlobalRoamer® is a complete IREG management tool, supporting IR24, IR25, IR35, IR38, IR50, IR32/60, and NG.112 since the successful execution of these test suites, is a prerequisite for a successful international roaming agreement between mobile network operators.

Align VoLTE QoE with expected revenues

As the number of 2G and 3G networks decrease, IP Multimedia Services (IMS) come as the enabler for Voice over LTE (VoLTE), RCS, VoWiFi, and SMSoIP. A key solution that allows operators to diversify offerings, implement new pricing models, and partner or compete with OTT players. Mobileum tackles the complexity and interoperability issues associated with legacy technologies, especially in roaming, when two networks and interconnecting parties are involved.

The VoLTE roaming testing solution guarantees your VoLTE subscribers the same supplementary voice services as they expect in traditional 2G/3G networks, e.g. call waiting, call hold, etc. It allows stack adaptation and automated periodic testing to ensure QoS & QoE by monitoring performance issues in real time. The testing scenarios validate:

Proactive Revenue Assurance

Test call generators (TCG) are often considered an engineering tool to gauge the quality of network functions. Automated test call generators, such as Mobileum’s GlobalRoamer®, can also proactively enhance revenue assurance by monitoring the completion, accuracy, and timeliness of events. For example, call scenarios can be replicated using the test call generator (TCG) functionalities of Mobileum’s GlobalRoamer® and then fed into the RA system to determine if any configuration performed will impact revenue or identify accidental misconfigurations.

Support for APP testing

Mobile apps are a global growth market, with a lot of new apps being developed and available to end-users every day. GlobalRoamer® is a powerful testing tool that is able to test the most popular Apps in the target mobile network or Wi-Fi network to ensure the apps run smoothly and as expected in every network. Other features that can be used from GlobalRoamer® are related to operator native app testing (Roaming pack purchase, prepaid top-up, balance check), enterprise app testing (to ensure pre-lunch validation before going to market), and enterprise web portal navigation.
