Ensuring the 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.

Over 750 Telecom companies, in more than 150 countries, are scaling their business with Mobileum solutions.

Monitor multiple service scenarios in your network

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.

Are you getting the VoLTE customer experience and revenue you expected?

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. It is a key solution for MNOs that allows operators to diversify offerings, implement new pricing models, and partner or compete with OTT players. Mobileum offers solutions to tackle the complexity and interoperability issues associated with legacy technologies, especially in roaming, when two networks and interconnecting parties are involved.

Mobileum’s 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 real-time. 

Our testing scenarios verify: 
      • VoLTE/RCS/SMSoIP basic access
      • Voice quality with VoLTE
      • SMS and RCS performance
      • SSoIMS functionality

Can you prevent, detect and manage fraud, all from a single platform? If not, it’s time to change your fraud management software.

Your ally for roaming fraud detection

Roaming traffic contributes a significant percentage to an operator's revenue - and even a higher percentage to the operator's margin. To protect the health of the business, CSPs need to closely monitor the roaming experience, charging accuracy, and fraud control of inbound roamers on its network plus outbound roamers on its roaming partner networks. GlobalRoamer® enables service providers to test call scenarios to prevent fraudulent situations such as wholesale fraud, CLI spoofing, SIM box detection, OTT bypass, or False Answer Supervision (FAS).

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.
