## Abstract

An information processing apparatus of this invention directed to a process for adjusting a switching interval which defines an interval between two switching operations that change the activation state of the base band units. The apparatus comprises a traffic history storage unit that stores traffic history data, and a control unit that determines the switching interval based on the traffic history data stored in the traffic history storage.

## Claims

### Claim 1

An information processing apparatus for adjusting a switching interval which defines an interval between two switching operations that change the activation state of base band units, comprising:
a traffic history storage that stores traffic history data; and
a controller that calculates saved costs for different switching intervals based on traffic history data during a selected period of time and determines the switching interval based on the traffic history data stored in the traffic history storage.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the controller further calculates extra costs for different switching intervals based on the traffic history data during the selected period of time.

### Claim 3 (depends on 2)

The apparatus according to claim 2, wherein the controller determines the switching interval which maximizes a difference between one of the saved costs and one of the extra costs.

### Claim 4

An information processing method of adjusting a switching interval which defines an interval between two switching operations that change the activation state of base band units, comprising:
calculating saved costs for different switching intervals based on traffic history data stored in a traffic history storage during a selected period of time, and
determining a switching interval among the different switching intervals by using the calculated saved costs.

### Claim 5 (depends on 4)

The method according to claim 4, further comprising:
calculating extra costs for each of the different switching intervals based on the traffic history data,
wherein the switching interval is selected among the different switching intervals based on a difference between the calculated saved cost and the calculated extra cost.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the switching interval, which maximizes a difference between one of the saved costs and one of the extra costs, is determined.

### Claim 7

A non-transitory computer readable medium storing a control program of an apparatus that adjusts a switching interval which defines an interval between two switching operations that change the activation state of base band units, which causes a computer to execute:
calculating saved costs for different switching intervals based on traffic history data stored in a traffic history storage during a selected period of time, and
determining a switching interval among the different switching intervals by using the calculated saved costs.
