The Full IP Core Network
Jean‐Gabriel Rémy, Charlotte Letamendia · 2014
Fixed mobile convergence (FMC) is the answer to the desire of consumers to be connected anytime anywhere and from any device. This requires: fixed and wireless broadband; IP Multimedia Subsystem (IMS); Session Initiation Protocol (SIP): Voice over Internet Protocol (VoIP), and common service delivery platform. 3rd Generation Partnership Project (3GPP) has taken IMS as the core of its telecommunication standards. The new blocks specific to Evolved UMTS evolution, also known as the evolved packet system (EPS), are the evolved packet core (EPC) and the Evolved UTRAN (or E-UTRAN). VoLTE is based on the IMS network, with specific profiles for control and media planes of voice service on LTE defined by GSMA in PRD IR.92. While much attention has been focused on LTE data rates, another important parameter, latency, is critical to enable a number of applications particularly voice services (VoLTE) or real time television.
