Abstract

A communication control device including an acquisition unit configured to acquire quality-related information regarding quality of a backhaul line to be used for providing control-related information regarding control in a control scheme of radio communication to a communication node to which the control scheme is applied, and a control unit configured to control the application of the control scheme to the communication node based on the quality-related information.

Claims

1. A communication device, comprising:

at least one processor configured to;

transmit a request message associated with a quality of a backhaul link to a communication node,

wherein the communication node measures at least a first part of quality-related information associated with the quality of the backhaul link based on the request message;

acquire at least the first part of the quality-related information associated with the quality of the backhaul link, via a response message from the communication node;

measure at least a second part of the quality-related information for the quality of the backhaul link, based on the response message;

generate at least the second part of the quality-related information for the quality of the backhaul link based on the measurement of at least the second part of the quality-related information for the quality of the backhaul link, wherein

the measurement of at least the first part of the quality-related information and the measurement of at least the second part of the quality-related information are repeated for a plurality of times; and

provide at least the second part of the quality-related information to the communication node.

2. The communication device according to claim 1, wherein

the backhaul link is a combination of a plurality of individual backhaul links, and

each of at least the first part of the quality-related information and at least the second part of the quality-related information is information associated with a quality of at least one respective individual backhaul link of the plurality of individual backhaul links.

3. The communication device according to claim 1, wherein

the request message includes a current request index and a total number of a plurality of request messages, and

the current request index indicates an order of the request message among the plurality of request messages.

4. The communication device according to claim 1, wherein

the response message includes a total number of a plurality of response messages, a current response index, and a measurement result of at least the first part of the quality-related information associated with the quality of the backhaul link.

5. The communication device according to claim 1, wherein

the request message includes a request flag for the measurement of the quality of the backhaul link, and

the request flag indicates a type of quality corresponding to the measurement of the quality of the backhaul link.

6. A method, comprising:

transmitting a request message associated with a quality of a backhaul link to a communication node,

wherein the communication node measures at least a first part of quality-related information associated with the quality of the backhaul link based on the request message;

acquiring at least the first part of the quality-related information associated with the quality of the backhaul link, via a response message from the communication node;

measuring at least a second part of the quality-related information for the quality of the backhaul link, based on the response message;

generating at least the second part of the quality-related information for the quality of the backhaul link based on the measurement of at least the second part of the quality-related information for the quality of the backhaul link, wherein

the measurement of at least the first part of the quality-related information and the measurement of at least the second part of the quality-related information are repeated for a plurality of times; and

providing at least the second part of the quality-related information to the communication node.

7. The method according to claim 6, wherein

the backhaul link is a combination of a plurality of individual backhaul links, and

each of at least the first part of the quality-related information and at least the second part of the quality-related information is information associated with a quality of at least one respective individual backhaul link from the plurality of individual backhaul links.

8. The method according to claim 6, wherein

the request message includes a current request index and a total number of a plurality of request messages, and

the current request index indicates an order of the request message among the plurality of request messages.

9. The method according to claim 6, wherein

the response message includes a total number of a plurality of response messages, a current response index, and a measurement result of at least the first part of the quality-related information associated with the quality of the backhaul link.

10. The method according to claim 6, wherein

the request message includes a request flag for the measurement of the quality of the backhaul link, and

the request flag indicates a type of quality corresponding to the measurement of the quality of the backhaul link.

11. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a processor, cause the processor to execute operations, the operations comprising:

transmitting a request message associated with a quality of a backhaul link to a communication node,

wherein the communication node measures at least a first part of quality-related information associated with the quality of the backhaul link based on the request message;

acquiring at least the first part of the quality-related information associated with the quality of the backhaul link, via a response message from the communication node;

measuring at least a second part of the quality-related information for the quality of the backhaul link, based on the response message;

generating at least the second part of the quality-related information for the quality of the backhaul link based on the measurement of at least the second part of the quality-related information for the quality of the backhaul link, wherein

the measurement of at least the first part of the quality-related information and the measurement of at least the second part of the quality-related information are repeated for a plurality of times; and

providing at least the second part of the quality-related information to the communication node.

12. The non-transitory computer-readable medium according to claim 11, wherein

the backhaul link is a combination of a plurality of individual backhaul links, and

each of at least the first part of the quality-related information and at least the second part of the quality-related information is information associated with a quality of at least one respective individual backhaul link of the plurality of individual backhaul links.

13. The non-transitory computer-readable medium according to claim 11, wherein

the request message includes a current request index and a total number of a plurality of request messages, and

the current request index indicates an order of the request message among the plurality of request messages.

14. The non-transitory computer-readable medium according to claim 11, wherein

the response message includes a total number of a plurality of response messages, a current response index, and a measurement result of at least the first part of the quality-related information associated with the quality of the backhaul link.

15. The non-transitory computer-readable medium according to claim 11,
