Full Description
This document specifies the Stage 2 system description for IP flow mobility between a 3GPP and a WLAN. The technical solution is based on the working principles of DSMIPv6 [2] and it is applicable to both the Evolved Packet System and the I-WLAN mobility architecture.The specification covers the system description of seamless WLAN offload and IP flow mobility between 3GPP and WLAN as well as the respective interactions with the PCC and ANDSF frameworks. The system description for nonseamless WLAN offload is covered in 3GPP TS 23.402 [3].
This document specifies also the detailed extensions to S2c [3] and H1 [4] reference points for IP flow mobility. The extensions to the PCC and to the ANDSF framework are specified respectively in 3GPP TS 23.203 [5] and in 3GPP TS 23.402 [3].
