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. 3GPP UMTS Network Architecture

Uu interfacecommunicate between UE and UTRAN
CNCircuit switched part Packet switched part
Iu interfacecarriers signal between UTRAN and CN
UEMobile Termination (MT) Terminal equipment (TE)
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)
Figure 2-1 The UMTS packet-switched (PS) domain network and user plane protocols
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.
Figure 4. PDP context activation
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
