Abstract

[Problem] To provide a site position priority order determination device and associated method with which it is possible to create a high-reliability site position priority order list in a shorter time. [Solution] The present invention has: a radio communication apparatus; a site position priority calculation unit for calculating the degree of nonattainment and the estimated degree of attainment for target service quality at a site position, the degree of tightness of a cell load, the degree of cell capacity supplied in response to demand traffic, and the degree of dominance of competing companies regarding service quality, calculating the weighted sum of these values, and outputting the result as site position priority; a site position priority storage unit for saving the individual site position priority per site position; and a site position priority order determination unit for determining, on the basis of the site position priority per site position, the priority order of a site position at which a new wireless base station is installed, and outputting a site position priority order list indicating the determined priority order of the site position.

Claims

1. A site position priority order determination device, comprising:

a radio communication apparatus that is capable of measuring a reception level and reception quality of a radio signal in communication with a radio base station existing at a periphery;

a site position priority calculation unit for actually measuring service quality at a site position at which a new radio base station is to be installed by;

transmitting and receiving data to and from the radio base station existing at the periphery using the radio communication apparatus, and calculating a nonattainment degree of target service quality based on the measured value of the service quality and, in conjunction therewith;

calculating an estimated attainment degree of the target service quality as a result of installing the new radio base station,

further calculating a tightness degree of cell load at the site position and a cell capacity supply degree to demand traffic and a competing company degree of dominance regarding the service quality at the site position, and

using a parameter set supplied from an outside party or person as a site position priority, determining weighted values of the nonattainment degree of target service quality, the estimated attainment degree of target service quality, the tightness degree of cell load, the cell capacity supply degree to demand traffic, and the competing company degree of dominance regarding the service quality at the site position, and calculating and outputting a weighted sum of the weighted values;

a site position priority storage unit for storing the site position priority with respect to each of the site positions, which is output from the site position priority calculation unit; and

a site position priority order determination unit for reading out the site position priority with respect to each of the site positions, which is stored in the site position priority storage unit, determining priority orders of the site positions based on the site position priorities, and outputting a site position priority order list indicating the determined priority orders of the site positions.

2. The site position priority order determination device according to claim 1, further comprising:

a plurality of site position priority calculation units; and

a co-siting/RAN sharing time site position priority weighted sum calculation unit for calculating and outputting a weighted sum of the site position priorities each of which is output from one of the respective site position priority calculation units using a parameter set supplied from an outside,

wherein each of the plurality of site position priority calculation units calculates a site position priority for one of different radio communication operators.

3. The site position priority order determination device according to claim 1, wherein

the service quality is a throughput that indicates a data amount per unit time that the radio communication apparatus is capable of communicating with the radio base station.

4. The site position priority order determination device according to claim 1, wherein

in the new radio base stations, a radio base station that manages a small cell the covered area of which is smaller than a macro cell is included.

5. A site position priority order determination method, comprising:

by use of a radio communication apparatus that is capable of measuring a reception level and reception quality of a radio signal in communication with a radio base station existing at a periphery, actually measuring service quality at a site position at which a new radio base station is to be installed by transmitting and receiving data to and from the radio base station existing at the periphery;

calculating a nonattainment degree of target service quality based on the measured value of the service quality and, in conjunction therewith, calculating an estimated attainment degree of the target service quality as a result of installing the new radio base station;

further calculating a tightness degree of cell load at the site position and a cell capacity supply degree to demand traffic and a competing company degree of dominance regarding the service quality at the site position, and, using a parameter set supplied from an outside party or person as a site position priority, determining weighted values of the nonattainment degree of target service quality, the estimated attainment degree of target service quality, the tightness degree of cell load, the cell capacity supply degree to demand traffic, and the competing company degree of dominance regarding the service quality at the site position, and calculating and outputting a weighted sum of the weighted values;

storing the site position priority with respect to each of the site positions in a storage device; and

reading out the site position priority with respect to each of the site positions, which is stored in the storage device, determining the priority orders of site positions at which the new radio base station is to be installed based on the site position priorities, and outputting a site position priority order list indicating the determined priority orders of site positions.

6. The site position priority order determination method according to claim 5, further comprising:

calculating the site position priority for each of different radio communication operators; and

calculating and outputting a weighted sum of a plurality of the site position priorities using a parameter set supplied from an outside.

7. A non-transitory storage medium storing a program for site position priority order determination, the program making a computer execute steps of:

by use of a radio communication apparatus that is capable of measuring a reception level and reception quality of a radio signal in communication with a radio base station existing at a periphery, actually measuring service quality at a site position at which a new radio base station is to be installed by transmitting and receiving data to and from the radio base station existing at the periphery;

calculating a nonattainment degree of target service quality based on the measured value of the service quality and, in conjunction therewith, calculating an estimated attainment degree of the target service quality as a result of installing the new radio base station;

further calculating a tightness degree of cell load at the site position and a cell capacity supply degree to demand traffic and a competing company degree of dominance regarding the service quality at the site position, and, using a parameter set supplied from an outside party or person as a site position priority, determining weighted values of the nonattainment degree of target service quality, the estimated attainment degree of target service quality, the tightness degree of cell load, the cell capacity supply degree to demand traffic, and the competing company degree of dominance regarding the service quality at the site position, and calculating and outputting a weighted sum of the weighted values;

storing the site position priority with respect to each of the site positions in a storage device; and

reading out the site position priority with respect to each of the site positions, which is stored in the storage device, determining the priority orders of site positions at which the new radio base station is to be installed based on the site position priorities, and outputting a site position priority order list indicating the determined priority orders of site positions.
