• UMTS network architecture consists of three domains:
– Core Network (CN) : To provide switching, routing and transit for user traffic.
– UMTS Terrestrial Radio Access Network (UTRAN) : Provides the air interface access method for User Equipment.
– User Equipment (UE) : Terminals work as air interface counterpart for Node B. The various identities are: IMSI, TMSI, P-TMSI, TLLI, MSISDN, IMEI, IMEISV.
