Abstract
The mobile technology 4G, known as Long Term Evolution (LTE), offers very high peak data, but, since it was designed specifically for data traffic, voice support is absent. So one problematic aspect is providing voice support or having voice continuity when the user moves out of LTE coverage. The most feasible solutions are CS fallback, Voice over LTE via Generic Access (VoLGA), Single Radio Voice Call Continuity (SRVCC) and third party voice service like Skype. These solutions are discussed and compared. There are also suggested the best options for providing voice over LTE, depending on the different types of network that an operator has already deployed. Since 2 out of 4 solutions described in this paper interact with IMS, in order to demonstrate the concepts, we have designed a testing configuration, based on our own-developed LTE network simulator, 4GSim and OpenIMS Core.
