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.
The present document 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 3GPP TS 24.303  and will specify additional details specific to the 3GPP I-WLAN and GPRS systems in the context of mobility.
