Tata Gears Up for International VoLTE

Comments Off on Tata Gears Up for International VoLTE 22

Tata Communications to supply Voice over LTE calling (VoLTE) to its  global community of IPX-connected service providers.

VoLTE will allow mobile network operators to offer HD voice over their LTE / 4G networks. VoLTE is viewed as a critical next step in continuing to deliver a high quality voice experience, a release from the provider said.

It offers customers HD Voice, while enabling mobile network operators to operate on the basis of an all-IP infrastructure. This is significant in that it produces operational efficiencies and the required foundation for deploying new services, as well as integration for further applications aimed at improving user experience.

For mobile network operators, the improved quality leads to increased usage, and ultimately, better revenues. Mobile voice quality issues are an ongoing concern for network operators and investing in VoLTE is set to greatly reduce customer churn and improve the customer experience.

Analysts estimate that VoLTE services combined with OTT VoIP are set to become a $16 billion business by 2017.

New capabilities to enable enhanced network readiness include, HD Voice support and interoperability between fixed and mobile networks, as well as SIP IMS support. This means that HD calls are no longer limited to VoLTE-to-VoLTE handsets, but to any HD-enabled user, including fixed.

Tata Communications has also deployed new capabilities to detect whether a call is HD in order to route it in such a way that the core benefits and features of HD are projected outside of the mobile operator’s network.

“Adding VoLTE to the portfolio also provides mobile operators with a potential competitive advantage over OTT providers, who may not be able to match the quality of experience. This is especially true as video calling over LTE will be the natural evolution of VoLTE,” Christian Michaud, SVP Product & Business Strategy, Global Voice Services, Tata Communications, said.

HD Voice is enabled by wideband codecs, with AMR-WB designed specifically for VoLTE, and mobile voice networks. Codec-aware routing allows Tata Communications to detect the codec being requested for the call as it is being setup and to automatically route according codec-specific rules and logic.
