This document specifies the signalling procedures for handling the mobility of a UE between 3GPP Wireless Local
Area Network Interworking (I-WLAN) and GPRS systems.
This TS is applicable to the User Equipment (UE) and the network nodes supporting mobility between
3GPP I-WLAN and GPRS systems.
In addition, the present document specifies the procedures used between the UE and the network nodes for the attach and the detach cases. It also specifies how the UE performs handover when moving from 3GPP I-WLAN to GPRS
systems and vice-versa.
This document is based on DSMIPv6 procedures specified in TS 24.303
and will specify additional details
specific to the 3GPP I-WLAN and GPRS systems in the context of mobility.
