<P> UTRAN ( short for `` Universal Terrestrial Radio Access Network '' ) is a collective term for the network and equipment that connects mobile handsets to the public telephone network or the Internet . It contains the base stations , which are called Node B 's and Radio Network Controllers ( RNCs ) which make up the UMTS radio access network . This communications network , commonly referred to as 3G ( for 3rd Generation Wireless Mobile Communication Technology ) , can carry many traffic types from real - time Circuit Switched to IP based Packet Switched . The UTRAN allows connectivity between the UE ( user equipment ) and the core network . </P>
