Abstract

A method and apparatus of measuring a packet throughput in a wireless communication system are provided. When determining a reference time for estimating packet throughput, a receiver determines the time that a data burst starts or ends in order to estimate the packet throughput considering a change in the data burst of the transmitter buffer. A measurement period is defined through the determined start time and end time of the data burst, and packet throughput is measured considering the total amount of the received data burst. The throughput of packet data may be estimated by each base station based on the same standard rule, so that the measured packet throughput values may be reliable, thus allowing the operator to make use of it as a parameter for MDT.

Claims

1. A method of measuring a throughput in a wireless communication system, the method comprising:

determining, by a base station, a start point (T2) at which a data burst begins, wherein the start point (T2) is a point in time when a first transmission begins after the base station estimates that a user equipment'"'"'s buffer size becomes greater than zero;

determining, by the base station, an end point (T1) at which the data burst ends;

determining, by the base station, a data volume counted on a Packet Data Convergence Protocol (PDCP) service data unit (SDU) bits in uplink for the data burst excluding data transmitted in a last Transmission Time Interval (TTI) used for transmission of the data burst; and

measuring, by the base station, a scheduled IP throughput of the data burst for Minimization of Drive Test (MDT) by using the start point (T2), the end point (T1), and the data volume.

2. The method of claim 1, wherein the start point (T2) is a point in time when a first transmission begins after the base station estimates that the user equipment'"'"'s buffer size becomes greater than zero for a radio bearer of the user equipment.

3. The method of claim 2, wherein the end point (T1) is a point in time when the base station estimates that the user equipment'"'"'s buffer size becomes zero for a radio bearer of the user equipment.

4. The method of claim 1, wherein the scheduled IP throughput of the data burst is measured by following equation:

5. The method of claim 1, wherein the PDCP SDU bits are received in a Medium Access Control (MAC) upper service access point.

6. A base station for performing a measurement of a throughput in a wireless communication system, the base station comprising:

a radio frequency(RF) unit for receiving a radio signal; and

a processor, operatively coupled with the RF unit, configured to;

determine a start point (T2) at which a data burst begins, wherein the start point (T2) is a point in time when a first transmission begins after the base station estimates that a user equipment'"'"'s buffer size becomes greater than zero;

determine an end point (T1) at which the data burst ends;

determine a data volume counted on a Packet Data Convergence Protocol (PDCP) service data unit (SDU) bits in uplink for the data burst excluding data transmitted in a last Transmission Time Interval (TTI) used for transmission of the data burst; and

measuring a scheduled IP throughput of the data burst for Minimization of Drive Test (MDT) by using the start point (T2), the end point (T1), and the data volume.

7. The base station of claim 6, wherein the start point (T2) is a point in time when a first transmission begins after the base station estimates that the user equipment'"'"'s buffer size becomes greater than zero for a radio bearer of the user equipment.

8. The base station of claim 7, wherein the end point (T1) is a point in time when the base station estimates that the user equipment'"'"'s buffer size becomes zero for a radio bearer of the user equipment.

9. The base station of claim 6, wherein the scheduled IP throughput of the data burst is measured by following equation:

10. The base station of claim 6, wherein the PDCP SDU bits are received in a Medium Access Control (MAC) upper service access point.
