This document specifies the stage 2 service description for providing IP connectivity using non-3GPP accesses to the Evolved 3GPP Packet Switched domain. In addition, for E-UTRAN and non-3GPP accesses, the specification describes the Evolved 3GPP PS Domain where the protocols between its Core Network elements are IETF-based.
The specification covers both roaming and non-roaming scenarios and covers all aspects, including mobility between
3GPP and non 3GPP accesses, policy control and charging, and authentication, related to the usage of non-3GPP
