With Mavenir’s Inbound Roaming Solution for 4G/5G Voice, Communication Service Providers (CSPs) can ensure seamlessly connectivity and protect roaming revenue, while sunsetting 2G/3G networks to reallocate spectrum for 4G/5G services. The solution prevents income loss for CSP from incoming roaming subscribers using 4G/5G-enabled devices, even in absence of new VoLTE/VoNR roaming agreements between home and visited CSP.
BUSINESS NEED
As network capabilities evolve, CSPs across the globe are closing-down 2G and 3G infrastructure to optimize network management costs and reallocate spectrum for next-generation 4G and 5G services. Without careful planning, CSPs can lose the ability to support existing roaming partners — or form new roaming agreements with other CSPs – that do not support VoLTE/VoNR roaming services. Additionally, greenfield CSPs building only 4G or 5G networks do not have access to Circuit Switched (CS) networking capabilities but still need to co-operate with CSPs that may not want to invest in planning and setting up new infrastructure for VoLTE/VoNR roaming – preferring instead to rely on existing 2G/3G roaming agreements and network connectivity.
Mavenir’s cost-effective and resilient Inbound Roaming Solution for 4G/5G Voice successfully addresses these challenges and offers a critical route to revenue protection for greenfield CSPs offering only 4G/5G services, brownfield CSPs sunsetting their 2G and 3G networks, as well as IPX roaming providers.
SOLUTION
Mavenir’s Cloud-Native IMS-powered Inbound Roaming Solution for 4G/5G Voice allows roaming subscribers with VoLTE/VoNR-enabled devices to make calls even in the absence of a VoLTE/VoNR roaming agreement between the home and visited CSPs of the subscriber.
This powerful platform solution enables the visited CSP, who has retired its 2G/3G network having roaming agreement with the home CSP, to provide voice and data services to its inbound roaming subscribers – delivering service continuity and protecting inbound roaming revenue.
