Abstract

A method and apparatus of measuring a packet throughput using a timer 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 using a timer 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 by the timer, 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 of a data burst in a wireless communication system, the method comprising:

determining, by a base station, a start point (T2) at which the data burst begins using a timer;

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

measuring, by the base station, the throughput of the data burst based on the start point (T2) and the end point (T1),

wherein the throughput of the data burst is measured by a following equation;

2. The method of claim 1, wherein the start point (T2) is a point in time when the timer starts to run after receiving the first data block to indicate that a buffer size of the UE becomes greater than zero for at least one radio bearer of the UE.

3. The method of claim 1, wherein the end point (T1) is a point in time when the timer expires after receiving a last data block to indicate that a buffer size of the UE becomes zero for all radio bearers of the UE.

4. The method of claim 1, wherein the timer restarts to run, not to expire when a data block for the data burst is needed to be received by checking a sequence of the data block in a reception buffer.

5. The method of claim 1, wherein the first data block includes one of an MAC (medium access control) PDU (packet data unit), MAC SDU (service data unit), RLC (radio link control) PDU, RLC SDU, PDCP (packet data convergence protocol) PDU, or PDCP SDU.

6. The method of claim 1, wherein a value of the timer is signaled from the base station to the UE with one of an RRC (Radio Resource Control) message, MAC Control PDU, RLC Control PDU, or PDCP Control PDU.

7. A base station for measuring a throughput of a data burst 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 the data burst begins using a timer,

determine an end point (T1) at which the data burst ends using the timer, and

measure the throughput of the data burst based on the start point (T2) and the end point (T1),

wherein the throughput of the data burst is measured by a following equation;

8. The base station of claim 7, wherein the start point (T2) is a point in time when the timer starts to run after receiving the first data block to indicate that a buffer size of the UE becomes greater than zero for at least one radio bearer of the UE.

9. The base station of claim 7, wherein the end point (T1) is a point in time when the timer expires after receiving a last data block to indicate that a buffer size of the UE becomes zero for all radio bearers of the UE.

10. The base station of claim 7, wherein the timer restarts to run, not to expire when a data block for the data burst is needed to be received by checking a sequence of the data block in a reception buffer.

11. The base station of claim 7, wherein the first data block includes one of an MAC (medium access control) PDU (packet data unit), MAC SDU (service data unit), RLC (radio link control) PDU, RLC SDU, PDCP (packet data convergence protocol) PDU, or PDCP SDU.

12. The base station of claim 7, wherein a value of the timer is signaled from the base station to the UE with one of an RRC (Radio Resource Control) message, MAC Control PDU, RLC Control PDU, or PDCP Control PDU.
