The Radio Network Controller (RNC) is a governing element in the UMTS radio access network (UTRAN) and is responsible for controlling the Node Bs that are connected to it .

Universal Mobile Telecommunications System (UMTS)
Read moreOn what is the UMTS air interface based on?
UMTS air interface is based on DS CDMA , that is, user data bits are multiplied with a spreading sequence (consists of random bits called chips) and chip rate is much higher than symbol rate or data rate. This process spreads the user data signal to wider frequency band.
Read moreWhat are the interfaces of UMTS?
There are four interfaces connecting the UTRAN internally or externally to other functional entities: Iu, Uu, Iub and Iur . The Iu interface is an external interface that connects the RNC to the Core Network (CN). The Uu is also external, connecting Node B with the User Equipment (UE).
Read moreHow does UMTS network work?
UMTS relies on a packet-switched system . This allows cellular devices to send small “packets” of data to a destination, whereas circuit-switched networks require a point-to-point connection. In an old phone network, making a call meant reserving a line between the sender and receiver.
Read moreWhat is UMTS and LTE?
UMTS is the standard for 3G or third generation communications . LTE is the standard for the 4G or fourth generation standards . Data Rate. UMTS is an extension to 2G and offered better data rates compared to the 2G network. This employed packet switching which increased the speeds to a greater extent.

The GSM architecture consists of three major interconnected subsystems that interact with themselves and with users through certain network interface . The subsystems are Base Station Subsystem (BSS), Network Switching Subsystem (NSS) and Operational Support Subsystem (OSS).
