Base station and cell assignment method
First Claim
Patent Images
1. A base station comprising:
- a memory; and
a processor coupled to the memory, wherein the processor executes a process comprising;
counting number of terminals located in an area covered by the base station, for each of communication carriers, the communication carriers including a first communication carrier and a second communication carrier whose priority is lower than priority of the first communication carrier;
assigning each of a plurality of cells to any of the communication carriers based on the counted number of terminals, wherein each of the plurality of cells is a frequency band of the base station;
determining whether a shared cell is included in the plurality of cells, the shared cell being a cell that is available to all of the communication carriers;
when the shared cell is included in the plurality of cells, assigning the shared cell to the first communication carrier to increase number of cells assigned to the first communication carrier; and
when the shared cell is not included in the plurality of cells, assigning a cell that is assigned to the second communication carrier to the first communication carrier to increase the number of cells assigned to the first communication carrier.

Abstract
A counting unit of a base station counts the number of terminals located in an area covered by the base station for each of communication carriers corresponding to the terminals. An assigning unit assigns each of cells in a first group to any of the communication carriers, where each of the cells is a frequency band of the base station 10 and occupied by one terminal communicating with the cell.
