What is the difference between RCS and VoLTE?

VoLTE stands for Voice over LTE and it uses IP Multimedia Subsystem (IMS). It is simply a standard for high-speed wireless communication for mobile phones and different data terminals. It is based on theIPS multimedia subsystem networks technology which have specified profiles for control along with various media plans of voice service for LTE.

It has resulted as the voice service which are control and media planes that will be delivered as soon as the data flows within a particular LTE data bearer. There is little to no dependency for the legacy circuit-switched voice network to be maintained effectively. One of the perks of VoLTE is that it has three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM.

Rich Communication Services is simply a communication platform that operates between mobile-phone carriers and phone and carrier that is aimed at replacing SMS messages with a text-messaging system.
