Taqua, a leading supplier of mobile and fixed core networking IP convergence systems and applications, announced today at the LTE World Summit in Amsterdam the general availability of its Voice over WiFi (VoWiFi) Virtual Mobile Core for UMTS-based networks.
Taqua's Virtual Mobile Core VoWiFi solution enables carriers to offer voice and messaging services over WiFi networks, while keeping the user experience exactly the same whether the calls and messages go over WiFi or cellular. Depending upon signal strength, the phone selects the WiFi or cellular network to conduct incoming and outgoing calls and messages. This allows carriers to utilise any existing WiFi access point, reduce cellular spectrum load, and expand and enhance network coverage. Leveraging the success of Taqua's CDMA solution set that was launched by Sprint in February, Taqua has completed development of its new UMTS VoWiFi platform and has begun trialling the new UMTS solution with wireless and broadband operators.
"There are significant advantages for wireless and emerging competitive mobile carriers to utilize a seamless 'WiFi-first' model for mobile voice and messaging," said John Hoadley, Wireless CTO at Taqua. "All service providers should take full advantage of WiFi, as it's the largest network in the world. It is a very cost effective approach for carriers to combat the OTTs and to improve their coverage for voice and messaging services everywhere."
Taqua's seamless "WiFi-first" voice and messaging service is unlike any existing Over-the-Top (OTT) application. Taqua's solution conducts both cellular and WiFi calls from the phone's native dialer/messaging interface and existing phone number. Most OTT applications require a separate, downloadable interface, different subscriber contact identity (not the user's mobile number), and come with numerous subscriber conflicts.
In contrast, Taqua's solution enables cellular and WiFi calls from a single phone interface and the subscriber's existing phone number. The Taqua solution uses the phone's native dialer, contacts, call history and voice mail, as well as the native SMS, using the same message notifications, inbox and outbox. Subscribers will not notice the difference between calls made over WiFi or cellular. Taqua's solution will also work seamlessly with any standards-based native WiFi clients embedded in smartphones and tablets.
Seamless voice and messaging over WiFi is just one in a series of solutions that are available in Taqua's Virtual Mobile Core, which is designed to solve interworking challenges between 3G, small cell, WiFi, and 4G/LTE networks. Other applications include Single Radio Voice Call Continuity (SRVCC.)
Taqua is showcasing its Virtual Mobile Core's VoWiFi solution in booth 52a at the 2014 LTE World Summit on 23-25 June.
