Voice-Over-LTE(VoLTE) and Wi-Fi Calling have this year emerged as the most exciting services rolled out by Mobile Network Operators(MNOs) globally. Both services mark the comeback of telecom's voice business which has over the last decade suffered the onslaught of intense price wars, competition from Over-the-Top(OTT) applications and rapidly declining ARPUs.

In its latest whitepaper 'Wi-Fi Calling and VoLTE: The Latest in the Evolution of Voice Services', Openet captures the rebound of MNOs' voice business on the back of both Voice Over Wi-Fi(VoWiFi) and Voice-over-LTE technologies, and how their timely deployment is catalyzing the introduction of increasingly innovative services that will help MNOs to reclaim revenues lost in the voice business.

The whitepaper examines the huge potential of VoLTE as MNOs around the world continue to expand their LTE networks and start rolling out VoLTE services and looks at the growth in Wi-Fi hotspots, and how in combination, these factors fuel MNOs' shift to an all-IP network.

More importantly, the whitepaper highlights the key performance areas that MNOs should focus on, considering the fact that the delivery of voice services on IP networks introduces new complexities that are not normally associated with data services. Toward this end, the whitepaper provides insights into how a number of Business Support System(BSS) and other key functionalities within the network, including the Policy Control Rules Function (PCRF), Access Network Discovery and Selection Function (ANDSF) and a Flexible Charging System will enable MNOs to quickly develop and roll out VoLTE and Wi-Fi Calling services and ensure efficient and successful delivery of these services to their subscribers

The white paper also outlines the numerous benefits for both MNOs and subscribers arising from the introduction of VoLTE and Wi-Fi Calling services, including:

  • Enhanced Network Coverage and thus Lower Churn

  • Cost Savings

  • Recovery of Revenue Lost to OTT Apps

  • Enhanced Roaming Capabilities

  • Lower Roaming Costs

  • Superior Customer Experience via HD Voice and Native Dialing

..and shares Wi-Fi Calling services case studies including T-Mobile US, Everything Everywhere (EE) UK, Salt (formerly Orange) in Switzerland and Swisscom.

Learn this and much more on how MNOs can tap on VoLTE and VoWi-Fi to augment their revenues. Openet's 'Wi-Fi Calling and VoLTE: The Latest in the Evolution of Voice Services' white paper is now available for download.
