IMS is an IP-based digital network that complies with 3GPP standards, which is required to offer voice and multimedia services to subscribers in 4G and 5G communication networks. In 4G, IP-based voice transfer is defined under the heading VoLTE and IMS is added under the heading VoLTE. The prerequisite for providing voice, messaging and video services is the development of IMS infrastructure and IMS services built on it. The presence of VoLTE-based IMS systems is a common way to make voice, message and video calls between mobile operators. With IMS, subscribers of voice-based secondary services can be offered with the TAS (Telephony Application Server) system that can work integrated with IMS. As an integrated product, IMS & TAS offers significant benefits to mobile operators with lower costs, faster time to market, multiple vendor support, standard open interfaces, innovative multimedia services and many modern features.
