Abstract

Described are embodiments of a method for performance measurement of a communication device. The method comprises: executing active probing by a communication device coupled to another communication device via a network forming a communication link; reading operational data associated with the communication link in response to executing active probing; and measuring performance, by the communication device, of the communication link with reference to the communication link, the performance measured according to the read operational data.

First claim

The invention claimed is:

1. A method for performance measurement, the method comprising:
receiving one or more test patterns at a base station from a communication device, the one or more test patterns relating to an active probing process on a wireless channel in which channel performance is measured from the communication device to the base station;
generating operational data comprising retransmission counts transmitted from the base station to the communication device at a layer below layer 3 , the retransmission counts relate to throughput on the wireless channel during a passive probing process; and
monitoring channel performance of the wireless channel based on a combination of the active and passive probing processes.

2. The method of claim 1 , wherein the operational data further comprises one or more of:
data related to the wireless channel and its noise condition; and
counter values related to user data traffic between the base station and the communication device.

3. The method of claim 2 , wherein the operational data is relevant to one or more configuration settings of the base station.

4. The method of claim 1 , wherein the active probing and the passive probing are executed in combination under one or more configuration settings for operational data reading to choose a desirable configuration setting to operate the base station.

5. The method of claim 1 , wherein the active probing is executed adaptively and/or in real-time when diagnosis for the wireless channel is needed.

6. The method of claim 1 further comprising:
adjusting one or more configuration parameters of the base station according to the measured channel performance of the wireless channel.

7. The method of claim 6 , wherein the one or more configuration parameters comprise at least one of:
power;
frequency band and bandwidth in use;
beam-forming method;
modulation and coding scheme;
multiple antenna mode; and
Quality of Service (QoS) setting.

8. The method of claim 1 wherein the one or more test patterns comprise Ethernet packets.

9. A method for performance measurement, the method comprising:
receiving one or more test patterns at a communication device from a base station, the one or more test patterns relating to an active probing process on a wireless channel in which channel performance is measured from the base station to the communication device;
generating operational data comprising retransmission counts transmitted from the communication device to the base station at a layer below layer 3 , the retransmission counts relate to throughput on the wireless channel during a passive probing process; and
monitoring channel performance of the wireless channel based on a combination of the active and passive probing processes.

10. The method of claim 9 , wherein the operational data further comprises one or more of:
data related to the wireless channel and its noise condition; and
counter values related to user data traffic between the base station and the communication device.

11. The method of claim 10 , wherein the operational data is relevant to one or more current settings of the communication device.

12. The method of claim 9 , wherein the active probing and the passive probing are executed in combination under one or more configuration settings for operational data reading to choose a desirable configuration setting to operate the communication device.

13. The method of claim 9 further comprising:
adjusting one or more configuration parameters of the communication device according to the measured channel performance of the wireless channel.

14. A non-transitory computer-readable medium or media comprising one or more sequences of instructions which, when executed by at least one processor, causes steps for performance measurement comprising:
receiving, at a base station, one or more test patterns from a communication device, the one or more test patterns relating to an active probing process on a wireless channel in which channel performance is measured from the communication device to the base station;
generating, at the base station, operational data comprising retransmission counts transmitted from the base station to the communication device at a layer below layer 3, the retransmission counts relate to throughput on the wireless channel during a passive probing process; and
monitoring, at the base station, channel performance of the wireless channel based on a combination of the active and passive probing processes.

15. The non-transitory computer-readable medium or media of claim 14 , wherein the operational data further comprises one or more of:
data related to the wireless channel and its noise condition; and
counter values related to user data traffic between the base station and the communication device.

16. The non-transitory computer-readable medium or media of claim 15 , wherein the operational data is relevant to one or more configuration settings of the base station.

17. The non-transitory computer-readable medium or media of claim 16 , further comprising one or more sequences of instructions which, when executed by at least one processor, causes steps to be performed comprising:
choosing, among the one or more configuration settings, a desirable configuration setting to operate the base station based at least on the measured channel performance.

18. The non-transitory computer-readable medium or media of claim 14 , wherein the active probing is executed when diagnosis for the wireless channel is needed.

19. The non-transitory computer-readable medium or media of claim 16 , further comprising one or more sequences of instructions which, when executed by at least one processor, causes steps to be performed comprising:
adjusting one or more configuration parameters of the base station according to the measured channel performance of the wireless channel.

20. The non-transitory computer-readable medium or media of claim 19 , wherein the one or more configuration parameters comprise at least one of:
power;
frequency band and bandwidth in use;
beam-forming method;
modulation and coding scheme;
multiple antenna mode; and
Quality of Service (QoS) setting.
