A system for estimating a traffic rate of calls in system environments providing
wireless personal communication services on an open queuing network includes modules
that have functions of making three sets of nodes, "log_off", "log_on" and "active"
according to the status of communication terminal equipment, observing the number
of "log_on" and "active" terminals by minimum areas of each wireless personal communication
service, and predicting traffic probability by minimum areas. More specifically,
the present invention includes: a traffic parameter observation module for making
a set of nodes and collecting observations measured in real time on the respective
nodes; a regression analysis module for performing a regression analysis of the
observations to assume a prediction model for traffic rates of calls and to estimate
the traffic rates of internal-to-internal or external-to-internal calls; and a
resource allocation control module for determining whether to allocate resources
and how much of the resources to allocate according to the traffic rates of internal-to-internal
or external-to-internal calls.
