This common core is referred to as EPC (evolved packet core) and the full system is known as EPS (evolved packet system) which includes support for 3GPP radio access technologies (LTE, GSM and WCDMA/HSPA) as well as support for non-3GPP access technologies. Unlike its predecessor, EPC provides support for multiple
access technologies and provides for mobility between them, allowing end-users to move between, for example LTE, WLAN and other 3GPP and non-3GPP
accesses. The architecture, in comparison to the one used for 2G/3G packet core is also optimized for efficient payload handling; a so-called ‘flatter’ architecture.
