Abstract

A monitoring device for a distributed antenna system including at least two node units communicatively coupled to each other transmits, to at least one target node unit among the node units, a data dump command for a first target signal passing through a first signal path in the target node unit. The monitoring device receives, from the target node unit, response data corresponding to the data dump command. The monitoring device generates first quality information indicative of the quality of the first target signal by using the response data.

Claims

1. A monitoring device for a distributed antenna system including at least two node units communicatively coupled to each other, the monitoring device:

transmitting, to at least one target node unit among the node units, a data dump command for a first target signal passing through a first signal path in the target node unit;

receiving, from the target node unit, response data corresponding to the data dump command; and

generating first quality information indicative of the quality of the first target signal by using the response data.

2. The monitoring device of claim 1, wherein the response data is data stored in the target node unit while the first target signal is being processed by signal processing components related to the first signal path.

3. The monitoring device of claim 1, wherein the first quality information indicates a quality index for the first target signal,

wherein the quality index is related to at least one signal quality characteristic among spectrum, power, peak level in time domain, adjacent channel leakage ratio (ACLR), error vector magnitude (EVM), occupied bandwidth (OBW), spectrum emission mask (SEM), noise figure (NF), complementary cumulative distribution function (CCDF), signal to noise ratio (SNR), and spurious characteristic.

4. The monitoring device of claim 1, wherein the monitoring device comprises:

an interface unit configured to transmit the data dump command to the target node unit and receive the response data from the target node unit;

a controller configured to generate the data dump command and generate the first quality information by using the response data transmitted from the interface unit; and

a display unit configured to display the first quality information.

5. The monitoring device of claim 4, wherein the controller receives a manager'"'"'s dump request input through a predetermined graphic user interface (GUI) displayed on the display unit, generates the data dump command in response to the manager'"'"'s dump request input, and transmits the data dump command to the interface unit.

6. The monitoring device of claim 5, wherein the controller receives a manager'"'"'s information output request input through the predetermined GUI displayed on the display unit, and transmits the first quality information in response to the manager'"'"'s information output request input.

7. The monitoring device of claim 1, wherein the monitoring device receives, from the target node unit, report data on a second target signal passing through a second signal path in the target node unit, and generates second quality information indicative of the quality of the second target signal by using the report data.

8. The monitoring device of claim 7, wherein the report data is data stored in the target node unit while the second target signal is being processed by signal processing components related to the second signal path, and

wherein the report data is data transmitted from the target node unit regardless of the data dump command.

9. The monitoring device of claim 1, wherein the monitoring device analyzes whether a failure has occurred in the first signal path by using the response data, and generates first analysis information indicative of whether the failure has occurred in the first signal path, based on the analyzed result.

10. The monitoring device of claim 1, wherein the monitoring device detects whether a failure has occurred in the first signal path by using the response data, and transmits, to the target node unit, a predetermined control signal for controlling the signal processing components related to the first signal path, based on the detected result.

11. The monitoring device of claim 1, wherein the monitoring device is communicatively coupled to the target node unit through a wired or wireless network.

12. The monitoring device of claim 1, wherein the data dump command and the response data are transmitted through a control &

management (C&

M) channel or a specific channel between the monitoring device and the target node unit.

13. A monitoring device for a distributed antenna system including at least two node units communicatively coupled to each other, the monitoring device:

receiving, from at least one target node unit among the node units, report data on a target signal passing through a specific signal path in the target unit node; and

generating quality information indicative of the quality of the target signal by using the report data.

14. The monitoring device of claim 13, wherein the report data is data stored in the target node unit while the target signal is being processed by signal processing components related to the specific signal path.

15. The monitoring device of claim 13, wherein the quality information indicates a quality index for the target signal,

wherein the quality index is related to at least one signal quality characteristic among spectrum, power, peak level in time domain, ACLR, EVM, OBW, SEM, NF, CCDF, SNR, and spurious characteristic.

16. The monitoring device of claim 13, wherein the monitoring device receives, from the target node unit, self-analysis information indicative of whether a failure has occurred in the specific signal path in the target node unit.

17. The monitoring device of claim 16, wherein the monitoring device transmits, the target node unit, a predetermined control signal for controlling the signal processing components related to the specific signal path, based on the self-analysis information.
