Data transmission GSM (CSD) vs. GPRS/EDGE/UMTS
GSM
GPRS/EDGE/UMTS
 Fixed assignment of voice and data
channels
 Physical connection to the air

 Full bandwidth of a radio channel used
exclusively by one user

GPRS session uses several channel in
parallel
 User pays the radio channel the whole
time of allocation

Resources are only occupied for the
absolute period of time to transmit the
data package
 Pricing according to connection time

Pricing according to transferred volume
- “pay for activity”

- “pay for silence”

Dynamic assignment of voice and data
channels
Data transfer via packages

 Dynamic assignment of voice and data channel.
 GPRS/EDGE Session is able to use several channel in parallel.
 Resources are only occupied for the duration of transmission.
 GPRS/EDGE use existing GSM infrastructure
 GPRS/EDGE is a technology for packet oriented data communication (IP)
 GPRS/EDGE is global and area wide

Combined voice and
GPRS/EDGE data channel
UMTS – Core Netzwerk
 UMTS is using it‘s own radio access network,
separated from GSM
 UMTS is using W-CDMA (Wideband Code
Division Multiple Access) air interface standard
 The UTRAN Network logically cuts into RNSs
(Radio Network Subsystem)
 A RNS is a geographical region which is
managed by a RNC (Radio Network Controller).
 Single RNS‘s can be cuts into Location Areas
(LA)
 MSC, SGSN and GGSN are core components
of GSM/GPRS 2G network and are used by the
UMTS 3G network.
