3GPP 23.402 - Evolved Packet System (EPS) non-3GPP accesses

Rapporteur:  Mr. Ali, Irfan

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 accesses.
The procedures defined in the present document for WLAN access selection and PLMN selection (clause 16) replace, from Rel-11, the corresponding I-WLAN procedures specified in TS 23.234.
