Evolution From 3rd Generation Generic Access Networks to Voice over LTE Via Generic Access (VoLGA)
The paper gives a theoretical overview and comparison of 3rd Generation Generic Access Networks with LTE's VoLGA. Migration towards Packet Switched Technology brought significant changes on Voice and Text services because of their circuit switched nature. The Problem was identified and solution was introduced under 3rd Generation Partnership project. VoLGA is more likely to be adopted in the initial stage of LTE, but IMS can be the long term solution. Generic Access Technology is a 3rd generation term in wireless communications, where it helps to move voice and text (the conventional mobile-telephony services) to IP-Network.
