VoLTE: harness the power of LTE for communication and 4G voice

As subscribers demand more services for less money, it’s vitally important for operators to protect their profitability by reducing delivery costs. The answer is to eliminate the need for separate voice and data networks.

By providing VoLTE, an operator can enhance indoor coverage using Wi-Fi and extend its communication services with WebRTC. Voice over Wi-Fi (VoWiFi) and WebRTC use the same IMS core as VoLTE. Enable the same communication and multimedia services.

 

 

Why VoLTE and 4G calling is a critical enabler for 5G voice services

Deploying VoLTE is strategically important. It is typically part of the migration of voice services from 3G and legacy CS mobile networks to the 4G LTE network. VoLTE is based on the IMS architecture, so the rise of VoLTE also coincides with Communication Service Provider (CSP) adoption of IMS.

 

 

Take full advantage of the LTE network

  • Competitive, high-quality voice and video service over LTE
  • Fast time-to-market; quick, easy service development on top of LTE/ Wi-Fi
  • Full mobile voice service continuity
  • Full integration with existing network back office services

Evolution with VoLTE boost while CS Sun set

The Nokia VoLTE solution offers a clear evolutionary path. It allows operators to take full advantage of LTE network according industry standards coexisting fully with existing voice core. VoWiFi and fixed, converged IP expand the user experience and enable operators to bundle services to differentiate their offering.  

Nokia VoLTE core, including IMS /TAS, SBC and HSS, provides a truly robust and reliable next generation voice and messaging service core.    

Our Rich Communication Suite (RCS) allows operators to offer their customers capabilities that make the mobile even more central to their private and business lives.
