Abstract Abstract
This document describes different scenarios in Third Generation This document describes different scenarios in Third Generation
Partnership Project (3GPP) defined packet network, i.e. General Partnership Project (3GPP) defined packet network, i.e. General
Packet Radio Service (GPRS) that would need IP version 6 and IP Packet Radio Service (GPRS) that would need IP version 6 and IP
version 4 transition. The focus of this document is on the scenarios version 4 transition. The focus of this document is on the scenarios
where the User Equipment (UE) connects to nodes in other networks, where the User Equipment (UE) connects to nodes in other networks,
e.g. in the Internet. GPRS network internal transition scenarios, e.g. in the Internet. GPRS network internal transition scenarios,
i.e. between different GPRS elements in the network, are out of scope i.e. between different GPRS elements in the network, are out of scope
