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.


10/13

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)
