UMTS Protocol stack

image004.jpg

UMTS protocol stack consists of Access Stratum(AS) and Non Access Stratum(NAS). Access Stratum supports OSI-layer 1 to 3. It consists of PHY(layer 1), MAC(layer 2),RLC(layer 2) and RRC(layer 3). NAS or core network part is divided based on circuit switched(CS) or packet switched(PS) functionalities.


For CS functions it consists of CM(connection management) and MM(Mobility Management) layers. CM layer takes care of CC(Call Control), SM(supplementary Services) and SMS(Short Message Service). This is for UMTS CS control plane stack. For UMTS CS user plane stack NAS part do not include CM and MM layers but it includes application data layer protocol end to end (between UE-NodeB-RNC-MSC-Remote user).


For PS functions if consists of SM(session Management) and GMM(GPRS Mobility Management) layers. This is for UMTS PS control plane stack. For PS user plane stack, AS part incorporates PDCP(Packet Data Convergence) and NAS part incorporates packet protocol data(IP/PPP/..) and packet data applications(FTP/HTTP/..). PDCP does compression of IP headers, it may or may not exist in the UMTS protocol stack.


UMTS Channels

Logical,transport,physical channels

image005.jpg

As shown in the figure, there are three types of UMTS channels viz. logical channels(RLC layer), transport channels(MAC layer) and physical channels(PHY layer). As they tranverse between layers they map to other layer frames. For example logical channels are mapped to transport channels and transport channels are mapped tp physical channels.


UMTS logical channels

image006.jpg

As shown in the figure, UMTS/WCDMA logical channels are divided into control channels and traffic channels(DTCH,CTCH). As the name suggests traffic channels carry information(voice) annd control channels carry signalling information useful to establish and maintain connection between UE and network(NodeB).Following are the functions of each of these logical channels. Pls. note that DL stands for Downlink from network to UE and UL stands for Uplink from UE to Network.
DTCH(DL and UL, point to point)- Dedicated Traffic channel,carry user information. 
CTCH(unidirectional point to multi-point)-Common traffic channel. 
BCCH(DL broadcast)- Broadcast Control Channel, carry SYSTEM INFORMATION 
CCCH(Bidirectional)- Common Control Channel 
DCCH(Dedicated Control Channel, point to point bidirectional) 
PCCH(Paging Control Channel,DL)-carry paging information 
SHCCH(Shared Channel Control Channel,Bidirectional)
