Standardisation
3GPP is a umbrella aiming to form compromised standards by taking into
account, political, industrial, and commercial pressures from local specification
bodies:
ETSI European Telecommunication Standard Institute /Europe
ARIB Association of Radio Industries and Business /Japan
CWTS China Wireless Telecommunication Standard group /China
T1 Standardisation Committee T1 Telecommunications /US
TTA Telecommunication Technology Association /Korea

QoS Classification
Service Classes
Traffic Parameters
QoS Parameters
Service classes divide connections
into "main" classes
Traffic parameters define mainly
The bandwidth requirements
QoS parameters define finally theQoS of the connection: delay, jitter
buffer, etc.

UMTS QoS Service Class
UMTS network services have four types of traffic:
- Conversational class (voice, video telephony, video gaming)
- Streaming class (multimedia, video on demand, webcast)
- Interactive class (web browsing, network gaming, databaseaccess)
-Background class (email, SMS, downloading)
