The Huawei VoLTE solution evolves from CS to all-IP VoLTE networks to provide HD voice, HD video, and rich media services for subscribers. This solution retains and consolidates voice services and supports cloudfication.

The E2E Huawei VoLTE solution covers the IMS, EPC, CS, SDM, signaling, and LTE networks. Huawei has helped many carriers deploy commercial VoLTE networks, for example, the first eSRVCC-based commercial VoLTE network and the first NFV-based commercial VoLTE network. The Huawei VoLTE solution is the optimal choice for carriers.

Custormer Value

More Than Voice

Provide feature services in addition to plain voice, such as EVS HD voice, H.265 HD video, rich media (RCS, UC, and CaaS), multi-screen and multi-device services for subscribers.

Smooth Network Evolution

Always optimal cloud-based solution for network evolution and provide unified service experience for subscribers using difference access modes, meanwhile reducing carrier CAPEX.

Easy Deployment

Less impacts on the existing network, such as CS and IT system. VoLTE networks can be flexibly and quickly deployed to facilitate VoLTE commercial use.

Easy O&M

Bring carriers efficient O&M, such as visible E2E KPI monitoring, minute-level fault identification, second-level auto service provisioning, which help decreasing the OPEX.
