Introduction
Generations of cellular networksAnalog radio technologye.g. NMT and AMPs
Digital radio technologye.g. GSM and TDMA
The third generation (3G)
3GPP - Third Generation Partnership Project

1. 3GPP Background
Technical Specification Groups (TSGs):Radio Access Network (TSG- RAN)Core Network (TSG- CN)Service and System Aspects (TSG-SA)GPRS/ EDGE Radio Access Network (TSG-GERAN)Terminals (TSG- T; i.e., handsets or end host in IP language)

2.1 Packet-Switched Core Network
Consists of three main nodes :Serving GPRS Support Node (SGSN)Gateway GPRS Support Node (GGSN)Home Location Register (HLR)

2.2 Circuit-Switched Core Network
UTRAN connects to the Legacy Circuit Switched (CS) network through the Iu-CS interface

4. UMTS Core Network
Main components of CNSGSN, GGSN involved in forwarding the UE’s traffic HLR involved in authentication, authorization, and access control.

PDP context request message contains:
PDP type (e.g., IPv6 or IPv4),Access Point Name (APN)QoS/ filtering-related parameters

5. IPv6 in UMTSAddress configuration
Main requirements UE should be able to generate multiple addresses UE should not be assigned a single address
