Abstract

A communication control method is used in a mobile communication system that supports MDT (minimization of drive test). The communication control method has: a step (A) wherein a user terminal, which has established a connection with abase station, location information indicating the location of the user terminal to the base station based on an instruction from the base station; and a step (B) wherein the base station receiving the location information from the user terminal measures the throughput of communication with the user terminal.

Claims

1. A communication control method used in a mobile communication system supporting MDT (Minimization of Drive Test), comprising:

a step A of transmitting location information indicating a location of a user terminal establishing a connection with a base station based on an instruction from the base station, from the user terminal to the base station; and

a step B of measuring, by the base station receiving the location information from the user terminal, a throughput of communication with the user terminal.

2. The communication control method according to claim 1, wherein

in the step B, the base station measures a throughput of communication with the user terminal per unit time, and

the communication control method further comprising

a step C of associating the location information received from the user terminal with the throughput measured in the unit time corresponding to a reception timing of the location information.

3. The communication control method according to claim 1, wherein

in the step B, the base station individually measures an uplink throughput in the communication with the user terminal and a downlink throughput in the communication with the user terminal when the base station receives the location information from the user terminal.

4. The communication control method according to claim 1, wherein

in the step B, the base station measures a throughput per user terminal when the base station receives the location information from each of plural user terminals establishing connections with the base station.

5. The communication control method according to claim 1, wherein

in the step B, the base station measures a throughput per radio access bearer of the user terminal when the base station receives the location information from the user terminal.

6. A base station that establishes a connection with a user terminal in a mobile communication system supporting MDT (Minimization of Drive Test), comprising:

a receiver that receives location information indicating a location of the user terminal, wherein the location information is transmitted from the user terminal based on an instruction from the base station; and

a controller that measures a throughput of communication with the user terminal during a period in which the receiver receives the location information.

7. A user terminal that establishes a connection with a base station in a mobile communication system supporting MDT (Minimization of Drive Test), comprising:

a transmitter that transmits location information indicating a location of the user terminal to the base station, during a period in which the base station measures a throughput of communication with the user terminal, based on an instruction from the base station.
