– 3G GMSC (Gateway MSC) • Switch at the point where UMTS is connected to external CS networks. All incoming and outgoing CS connections go through GMSC. – 3G SGSN (Serving GPRS Support Node) • Similar to that of MSC / VLR but is used for Packet Switched (PS) services. The part of the network that is accessed via the SGSN is often referred to as

The overall radio access network, i.e. collectively all the Radio Network Subsystem is known as the UTRAN UMTS Radio Access Network. The radio network subsystem is also known as the UMTS Radio Access Network or UTRAN. The security functions of UMTS are based on what was implemented in GSM. Some of the security functions have been added and some existing have been improved. Encryption algorithm is stronger and included in base station (NODE-B) to radio network controller (RNC) interface , the application of authentication algorithms is stricter and subscriber confidentially is tighter.
