EXPLORE
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.
SOLUTION BENEFITS
Improved User Experience
Reduced Subscriber Churn
Investment Protection
High-Definition Voice Service for Roamers
Preserves Inbound Voice Roaming after Sunsetting 2G/3G Networks
Mavenir’s solution protects roaming revenue while the CSP optimizes wireless spectrum service provision.
Addresses Limited VoLTE/VoNR Penetration
VoLTE/VoNR roaming is complex, and implementation is still evolving , with many CSPs continuing to offer roaming services over 2G/3G, even when VoLTE/VoNR is implemented in the visited network. Mavenir’s solution ensures that the CSPs yet to implement VoLTE/VoNR are still able to provide voice roaming to subscribers visiting a VoLTE/VoNR CSP.
Improves Coverage and User Experience
Mavenir’s solution allows CSPs to provide a superior roaming voice service through VoLTE/VoNR – leveraging high-definition codecs – and enables CSPs to repurpose 2G/3G spectrum to offer a broader 4G/5G coverage, better indoor signal, and a superior user experience.
Reduces Complexity for Faster Time-To-Market
This innovative Inbound Roaming solution leverages decades of Mavenir’s leadership in providing IMS solutions – built on a deep knowledge of the processes used by CSPs – and cloud-native automation to provide a seamless deployment and a quick service launch.
Supports Future-Needs of the Network Deployment
VoLTE/VoNR roaming is defined by two reference architectures: Home-based Routing (S8HR/S9HR) and Local Breakout (LBO). In its recent specifications, the GSMA recommends S8HR/S9HR over LBO. Mavenir’s solution already supports the S8HR/S9HR architecture, future-proofing ongoing network deployments of CSPs.
