RNC - Main Functions


RNC Main Functionality To manage and secure an optimal usage of the radio resources

of the radio access network To control the mobility and handover within the radio access

network which also includes macro diversity To support Inter Radio Access Technology (IRAT) towards

other radio access systems.RNC provides Handover functions between UTRAN and GSM and Cell Change between UTRAN and GSM/GPRS

To support radio access bearer (RAB) services with Circuit Switched and Packet Switched data


RNC Main Functionality To provide a transparent bearer service for

control message between the Core Network and the UE (direct transfer)

To support control functions for paging of UEs, Signalling

Connection handling and Radio Access Bearer service handling

To provide element management functions To support UE positioning functions

Conversational RAB for AMR speech (Voice RAB - CS)

Interactive RAB (Internet access - PS)

Conversational RAB for UDI of 64 kbps (H.324M multimedia - CS)

Streaming RAB (CS) offers support for variable rate circuit switched data up to 57.6 kbps.

Multiple RAB offers support for multiple RABs (Voice and interactive/background) connected simultaneously to the same UE.

RNC Concepts - Radio access bearer


Control Plane

The Control Plane implements the control of the Radio Access Bearers and the connection between the UE and the Network from different aspects (Requesting the service, controlling different transmission resources, handover etc). Also a mechanism for the transparent transfer of NAS messages is included.

The Control Plane Includes the Application Protocol, i.e. RANAP, RNSAP or NBAP, and the Signalling Bearer for transporting the Application Protocol messages.

User Plane

The User Plane implements the actual radio access bearer service, i.e. carrying user Data/Data Stream(s) through the access stratum The Data Stream(s) is/are characterised by one or more frame protocols specified for that interface.

Logical Channel: A Logical Channel is an information streamdedicated to the transfer of a specific type ofinformation over the radio interface.

Transport Channel:The channels offered by the physical lay-er to Layer 2 for data transport betweenpeer L1 entities are called TransportChannels. Different types of TransportChannels are defined by how data is transferred, and with which characteristics the data is transferrede.g. whether usingdedicated or common Physical Channelare employed.

Physical Channel:

RNC Concepts - Channel Concepts

In FDD mode, a Physical Channel is definedby code, frequency and, in the Uplink, relative phase (I/Q). In TDD mode, a physical Channel is defined by code, frequency, and time slot.
