A device for estimating a communication load in a network, comprising:

• a communication section that is configured to acquire at least measurement data on a first quality indicator, which includes entire received power, and on a second quality indicator, which includes a signal-to-noise-and-interference ratio of a reference signal;
• and
• an estimation section that estimates communication load in the network by using at least the measurement data on the first and second quality indicators.

A radio station in a radio communication system, comprising:

• a communication section that is configured to acquire at least measurement data on a first quality indicator, which includes entire received power, and on a second quality indicator, which includes a signal-to-noise-and-interference ratio of a reference signal;
• and
• an estimation section that estimates a communication load in a network by using at least the measurement data on the first and second quality indicators.

An upper-level apparatus of a radio station in a radio communication system, comprising:

• a communication section that is configured to acquire from a radio station at least measurement data on a first quality indicator, which includes entire received power, and on a second quality indicator, which includes a signal-to-noise-and-interference ratio of a reference signal;
• and
• an estimation section that estimates a communication load in a network by using at least the measurement data on the first and second quality indicators.
