Abstract
The third generation networks and services present opportunities
to offer multimedia applications and services that meet
end-to-end quality of service requirements. Many of
the services will be able to use different QoS depending
upon the application and the type of data being transacted
(divided as speech, video, file transfer, secured money
transaction etc). In 3G Network, QoS implementation
is a layered architecture. It allows each bearer service
on a specific layer to offer its individual service
by using the services provided by the layer below. In
this paper, we shall discuss the QoS parameters provided
in the UMTS stack of 3G network and their mappings onto
RAB (Radio Access Bearer) parameters over Iu Interface.
Also discussed along the line is our understanding of
the implementation issues of these parameters in the
context of implementation of User Plane (i.e. IuUP and
GTPU).
