VoLTE Benefits

VoLTE Benefits
The reasons for using VoLTE instead of separated voice/data solutions are numerous:
1. VoLTE is simple and reliable: With its guaranteed QoS, VoLTE offers an operator’s subscribers a robust alternative to OTT VoIP in an easy-to-use mechanism. Users know that they can rely and enjoy carrier-grade services without disruption or uncertainty.
2. VoLTE exceeds OTT VoIP and even 3G voice quality: Through the use of Adaptive Multirate Wideband (AMR-WB) codecs (12.65kbps or 23.85kpbs) and QoS Class Identifier (QCI) SIP signalling, VoLTE provides “HD Voice” for a noticeably better end user experience compared to OTT VoIP and even 3G
3. VoLTE reduces the work to provide rich media services: As explained previously, in VoLTE, operators have a foundation for using RCS to enable video and file sharing, presence, instant messaging and enhanced phonebook services. An operator who has already implement VoLTE is closer to implementing RCS than a non-VoLTE operator.
4. VoLTE is spectrally efficient: Because of LTE’s all-IP architecture and new features in 3GPP releases (such as MIMO antenna technology), voice requires less bandwidth in LTE spectrum than it does in 2G/3G networks. Consequently operators have more available data capacity in their bands for a given voice load.
5. VoLTE reduces operator Opex: VoLTE simplifies the network by providing data and voice services on the same IP network, allowing operators to integrate network resources, optimize network and service management, and simplify service delivery.
6. VoLTE accelerates evolution to LTE: With VoLTE, an operator can offer voice service in its LTE spectrum while harvesting its 2G/3G spectrum for re-deploying additional LTE bandwidth. This migration process is easier for subscribers and limits operator upgrade costs.
