Abstract: PURPOSE: A system for estimating a call request rate in wireless communication environment and a method therefor are provided to classify previously known data and estimate the call request rate by a regression analysis method selected by a valid expression variable. CONSTITUTION: A traffic parameter observing module(10) sets a set having adjacent nodes in an open queuing network, and collects real-time measurement observing values for observing the number of busy objects in each node and the number of existence objects in a corresponding region. A regression analysis module(20) performs a regression analysis by the observing values collected in the traffic parameter observing module(10), supposes a call request rate estimation model, and estimates an internal generation and external inflow call request rate. A resource assignment management module(30) decides whether assigning resources according to the internal generation and external inflow call request rate estimated in the regression analysis module(20), and decides the assignment quantity of the resources.
