Abstract:
1. A user throughput geographical distribution estimating system for estimating the geographical distribution of user throughput in a cellular system, including user terminals and a base station for effecting wireless packet communications with user terminals inside in its own cell using a shared channel, comprising: a reception quality estimating means for estimating the reception quality of the shared channel at the location of a user terminal in said cell; a traffic information reading means for reading the traffic information on the estimation target area in which estimation of said reception quality was performed; a user throughput estimating means for estimating user throughput at the location of a user terminal in said cell, using a user throughput calculating function that receives as its input said reception quality of the shared channel at the location of the user terminal in said cell and said traffic information on the estimation target area and calculates user throughput; and a user terminal measuring means that travels in said cell for making actual measurement of said reception quality of the shared channel and said user throughput at the locations of user terminals in said cell, wherein said user throughput estimating means includes a function correcting means for correcting said user throughput calculating function in accordance with the relationship between the measurement of said reception quality of the shared channel and the measurement of said user throughput.
