Huawei has introduced Voice over WiFi (VoWiFi) calling support for its smartphones. The VoWiFi service, which is also called Wi-Fi Calling, enables users to voice call or video call on VoWiFi supported smartphones when a Wi-Fi connection is available. The users can even make VoWiFi call in airplane mode, and even when cellular network is not available.
Introducing this feature, Huawei spokesperson said, “Huawei is a global leader when it comes to communication technology. To open a new realm for advance modes of communication, we have introduced the VoWiFi calling feature for Huawei users in India. This will ensure that even if there is bad or no network, users can easily make calls, do video chat and communicate using their WiFi connections. Huawei aims to provide users ease of communication in every way and this feature has been launched to drive our vision of effective communication for all.”
According to Huawei, their 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.
The Huawei VoWiFi solution covers cellular telecommunications technologies, including radio access, core network and service capabilities, which provide a complete system description for mobile telecommunications. The 3GPP specifications also provide hooks for non-radio access to the core network, and for interworking with non-3GPP networks.
VoWiFi immensely benefits subscribers who often suffer from network issues at their home or workplace and will help operators to develop new business, ensure that users stick around and enhance competitiveness of voice solutions.
VoWiFi greatly improves indoor coverage, decreases cost of MVNO, provides cost efficient roaming solution, and increases carrier competitiveness. VoWiFi solution can solve the problem of indoor coverage network construction. As a significant complement for VoLTE, it provides more high-quality communication services for subscribers, enabling effective and clear communication for users.
VoWiFi solution support international roaming call. It gives users access to home country EPC network when abroad. Operators can provide users with relatively inexpensive roaming services for more high-end users. VoWiFi helps MVNO to reduce huge rental costs. VoWiFi users can access any Wi-Fi. It can help operators to decrease air interface rent and eventually help them make more profits.
