METHOD FOR COMPUTING OUTAGE PROBABILITY IN CELLULAR SYSTEM

摘要

The present invention relates to a method for calculating an unserviceable probability in a cellular system including a mobile receiver and a transmitter fixed to an arbitrary area and providing a mobile communication service to the receiver. Measure the actual path loss at any measurement location, calculate the path loss at that location, and then use the actual path loss and the calculated path loss to minimize the mean square error between the actual path loss and the calculated path loss at multiple locations. The break point is determined. After determining the path loss slope and the path loss standard deviation before the break point and the path loss slope and the path loss standard deviation after the break point, the determined break point and propagation characteristic parameters are used to determine the unserviceability probability before and after the break point. Calculate each outage probability of. As a result, the present invention can reduce the error of the outage prediction calculated at a specific path loss, and can provide a good communication service by providing a more accurate service unavailable probability to design a wireless network.
