The invention relates to a method for improving the quality of service for
data traffic in a mobile communication system, which uses GPRS (General
Packet Radio System). The invention may also be used in other types of
data networks, using packet switched traffic, e.g. the next generation
mobile telecommunication system UMTS. The improvement of the quality of
service is attained by defining a number of operator specific parameters,
which give better possilibity to monitor and control of the quality of
service within an area or for a given user. These parameters are then
used by the operator in order to give the user better service. Using this
invention the operator may in a better way attain the promised quality of
service, both on user and area basis.
