Abstract:
The operator of an UMTS radio access network has to define
timeout thresholds for the radio resource control protocol.
These timeouts have a strong influence on the quality of service
of the user traffic. In general long timeouts favour the call
setup time over the outage probability. For short timeouts it is
the other way around. Furthermore the reached quality of service
level depends on the load in the system. The load consists
of the number of users in the system and the services they are
using. This paper investigates the relationship between these
both parameters and the previously mentioned quality of service
parameters. We present results of five different timeout
settings, tested in various network settings. Simulations show
that very high timeout values have an insignificant influence on
call setup time but increase the outage. We highlight two timeout
settings which fits the requirements on user experience and
operators expectations best.
