Roaming Optimizer

Optimize roaming profitability

Roaming is a major revenue generator for operators that will be leveraged by mobile data in the coming years mainly driven by the enterprise segment. Carriers should therefore make sure that their network is fine-tuned to optimize roaming capture and retention. They should also check that they have established the right roaming partnerships with other international carriers to extend their service availability abroad.

Astellia’s RAN and Core roaming service assurance application is compliant with GSMA Global Roaming Quality (GRQ). It provides operators with increased visibility of service performance through advanced roaming KPI reporting and troubleshooting capabilities.

Increase roaming capture and retention

The application supplies a rich set of Key Performance Indicators (KPIs) enabling operators to locate capture points, analyze roaming traffic and investigate loss of roamers (LOR) on their network down to cell level.

QoS and QoE KPI examples:

• Traffic captured / lost / retrieved from competitors
• SOR (Steering Of Roamers) detection and measurement 
• MMS/email success rates
• Individual data throughput for data services

Troubleshooting

Operations can quickly detect roamers unable to access the network or experiencing poor service quality. They can perform end-to-end investigations, drill down into any roamer’s call or data sessions and isolate the issue's root causes such as poor network coverage, subscribers with no roaming rights or handsets not configured for roaming data usage.

Operations can then make informed decisions: take corrective actions accordingly, prioritize network optimization tasks on key roaming areas and perform performance benchmarks.

Ensure outbound roaming & interconnect efficiency

By monitoring both Core PS and CS networks, Astellia’s roaming assurance solution enables operators to monitor outbound traffic, measure service quality and roaming partnership efficiency. Using this information, operators are able to identify needs for new roaming alliances to extend roaming coverage and service continuity.
