CONTROL APPARATUS, REPRESENTATIVE BASE STATION AND BASE STATION CONTROL METHOD

摘要

According to one embodiment, a control apparatus includes a terminal information collecting unit, an area determining unit, a parameter calculator, and a parameter setting unit. The terminal information collecting unit calculates an SINR based on reception powers and physical cell IDs. The area determining unit determines a low-throughput area in reference to at least one of the SINRs and reception powers. The parameter calculator selects a base station that causes the low-throughput area and calculates an operation frequency and transmission power of the selected base station. The parameter setting unit sets the calculated operation frequency and transmission power with respect to the selected base station.

1. A control apparatus comprising:
a terminal information collecting unit configured to acquire reception powers and physical cell IDs from a plurality of base stations, calculate a Signal to Interference and Noise power Ratio (SINR) for each of a plurality of communication terminals that make radio communications with the plural base stations based on the acquired reception powers and physical cell IDs, and collect the acquired reception powers and physical cell IDs, wherein the reception powers are powers at which communication terminals receive a signal transmitted by each of the plural base stations, wherein the reception powers are transmitted from the communication terminal to a communicating base station, wherein the physical cell IDs are specifying base stations transmitting the signal, wherein the physical cell IDs are transmitted from the communication terminal to the communicating base station, an area determining unit configured to determine a low-throughput area in which sufficient throughput is not obtained in reference to at least one of the SINRs and reception powers, a parameter calculator configured to select a base station that causes the low-throughput area and calculate an operation frequency and transmission power of the selected base station to enhance the throughput of the low-throughput area, and a parameter setting unit configured to set the calculated operation frequency and transmission power in the selected base station.
