Subscribers use smartphones that support VoWiFi to initiate voice or video calls when Wi-Fi connection is available.The Huawei VoWiFi solution complies with 3GPP specifications and uses the EPC (ePDG), SingleSDB (3GPP AAA), and IMS as the core control architecture. Common subscribers can access IMS networks through Wi-Fi hotspots and use HD voice and video services, implementing seamless handovers to VoLTE networks.
VoWiFi greatly improves indoor coverage, decreases cost of MVNO, provides cost efficient roaming solution, and increases carrier competitiveness.
VoWiFi helps operators to develop new business, increase user stickiness, and enhance competitiveness of voice solutions.
VoWiFi helps MVNO to reduce huge rental costs. VoWiFi user can access any Wi-Fi. It can help operators to decrease air interface rent, make more profits
VoWiFi solution support international roaming call.It permits user access to home country EPC network when abroad. Operators can provide users with relatively inexpensive roaming services for more high-end users.
VoWiFi solution can well sovled the problem of indoor coverage network construction in early VoLTE.As a significant complement for VoLTE,It provides more high-quality communication services for subscribers.
VoWiFi greatly improves indoor coverage, decreases network rent, provide cost-efficient roaming solution, and increases carrier competitiveness. Huawei VoWiFi solution supports untrusted WLAN-based native VoWiFi and app-based VoWiFi.
The Huawei VoLTE solution evolves from CS to all-IP VoLTE networks to provide HD voice, HD video, and rich media services for subscribers.
The SingleSDB solution supports the integration of NEs, such as HLR, HSS, AAA, PCRF, ENUM, and EIR, enabling 2G, 3G, 4G, VoLTE subscriber data to be managed in a centralized manner.
The ICS solution provides unified services experience for 2G/3G subscribers and IMS subscribers, and simplify network architecture and O&M.
The IMS network provides mobile and fixed multimedia services and consists of functional entities CSCF and ASs.
The SE2900 is the next generation SBC oriented for all-IP VoLTE&FMC services. It uses an innovative carrier-class cloud platform and distributed architecture.
The UGW9811 is a gateway that supports GGSN, S-GW, and P-GW functions.
Huawei CDM can enable service activation and self-help service provision. user can enable VoWiFi service by themselves through the CDM, without any effort form operator.
