Wi-Fi Roaming Guidelines

September 27, 2018

The main purpose of this document is to describe the Wi-Fi Access to the Evolved 3GPP Packet Switched domain also known as the Evolved Packet Core (EPC) as defined in the 3GPP specifications TS 23.402 and TS 24.302, e.g. for devices based on GSMA PRD IR.51. The document is based on 3GPP Release 11 and later. The document concentrates on the roaming scenarios but also includes some non-roaming scenarios to give the full picture, including mobility between E-UTRAN and pre-E-UTRAN 3GPP radio access technologies, policy control and charging, and authentication.
