VoLTE means Voice over Long Term Evolution. Voice over LTE is a technology which is standards-based required to support voice calls over an LTE network.
It is one of the ultimate apps for 4G LTE networks. Mobile voice communication requirements are presenting new challenges for all IP mobile networks and VoLTE’s introduction emphasizes the need for advanced features. These features include QoS (Quality of Service), call admission control and session management.
When is VoLTE going to be introduced? Voice over LTE is very much similar to VoIP (Voice over Internet Protocol) that internet voice applications like Skype use to support voice calls over a broadband connection. Simply speaking, VoLTE allows voice to become an app that rides on a data network. The new protocol is likely to bring better and faster voice calls and even video chat to your cell phones. There will be no problem of voice minutes billing.
VoLTE is taking its time to roll out and it is not expected to appear in the market till next year. VoLTE is a foundation that will become necessary to the future of operator business models and to services like emergency calling. All mobile operators will not think in terms of whether to implement VoLTE or not but they will be contemplating on when and how to implement VoLTE.
This technology is going to become necessary because LTE is data-only networking technology. LTE turns the network around unlike 2G and 3G and uses Internet Protocol packets for all communication systems. It does not support conventional voice call technology. Hence, a new protocol and applications for Voice over LTE are required.
VoLTE will allow the users to talk and run the data simultaneously and this has become a problem for some phones presently. VoLTE applications will come with additional charge for extra features but so far not a single provider has come out with any details concerning VoLTE apps or pricing plans.
