Base station apparatus, edge user estimation method, and program

An edge user estimation method using a base station apparatus, which estimates whether or not each terminal device belonging to a communication cell of the present apparatus is an edge user present in an end area of the cell, wherein:

• a reception device receives from each terminal device, transmission power information which indicates transmission power of the terminal device;
• a registration device successively registers the transmission power information with a storage device;
• a statistical processing device computes a statistic used for estimating the terminal device present in the end area of the communication cell, with respect to a population which is the transmission power information stored in the storage device;
• a candidate extraction device extracts candidates for the terminal device present in the end area of the communication cell, based on the statistic computed by the statistical processing device;
• and
• an estimation device estimates the edge user from among the candidates extracted by the candidate extraction device.

A program that makes a base station apparatus, which estimates whether or not each terminal device belonging to a communication cell of the present apparatus is present in an end area of the cell, operate as:

• a reception device that receives from each terminal device, transmission power information which indicates transmission power of the terminal device;
• a registration device that successively registers the transmission power information with a storage device;
• a statistical processing device that computes a statistic used for estimating the terminal device present in the end area of the communication cell, with respect to a population which is the transmission power information stored in the storage device;
• a candidate extraction device that extracts candidates for the terminal device present in the end area of the communication cell, based on the statistic computed by the statistical processing device;
• and
• an estimation device that estimates the terminal device present in the end area of the communication cell from among the candidates extracted by the candidate extraction device.
