This paper describes the implementation process of the elements that involve a Core network of IMS technology for voice services over LTE (VoLTE) using an EPS network (Evolved Packet System) as a backbone network with SIP connections by Media Gateway Control Function (MGCF) to the CS domain network for feature-enhanced service convergence between 2G / 3G access technologies and 4G LTE access. The implementation of the VoLTE service is carried out through the self-registration of the IMS APN for the homologated terminals with voice over PS capability, for the convergence of CS and IMS domains the Single Radio Voice Call Continuity (SRVCC) function is used and the anchoring to the Core IMS of the terminating side by selecting the T-ADS domain following the 3rd Generation Partnership Project (3GPP) standard and the installation procedures of the network equipment manufacturers. The development of the project is a process of technological renewal of legacy CS domain equipment due to obsolescence and saturation, with the existing Core voice network close to its capacity limits due to the increase in users and voice services. The implementation of Core IMS is based on the fact that in communications networks worldwide, IMS technology is the standard process of technological evolution and replacement of CS domain networks with GERAN and UTRAN access technologies.
