Wireless Base Station for Communications Network
First Claim
1. A wireless base station having a plurality of wireless communication media each for providing a certain communication area, comprising:
- a measuring unit which measures, for each of the wireless communication media, radio environment factor representative of the quality of radio environment;
an environment predicting unit which predicts, for each of the communication media, said radio environment on the basis of the measured environment factor; and
a selecting unit which selects a communication media for communication on the basis of the output of the environment predicting unit;
wherein the environment predicting unit comprises;
an environment factor prediction value determining unit which monitors the trend in which said measured environment factor varies so as to determine an environment factor prediction value;
a correction magnitude calculating unit which calculates, on the basis of the difference between the determined trend of the environment factor variation and the measured environment factor, the magnitude of correction to be applied to the environment factor prediction value; and
an environment factor prediction value correcting unit which corrects the environment factor prediction value according to the tolerance for the base station'"'"'s failure risk for communication.

Abstract
A wireless base station includes: a trend factor regression expression calculator for determining, on the basis of measured wireless communication environment factor, the trend of the variation in the environment factor; a trend prediction value calculator for calculating, on the basis of the determined trend of the variation in the environment factor, the environment prediction value; an irregular variation factor calculator for calculating, on the basis of the difference between the determined trend of the environment factor variation and the measured environment factor, the magnitude of correction to be applied to the environment prediction value; and a radio environment prediction correction unit for correcting the environment prediction value according to the tolerance of the base station for its communication failure risk.
