Abstract

A communication control device includes a control unit. The control unit included in the communication control device performs control to notify an information processing device of a period for the information processing device to acquire information regarding a communication state in the information processing device. The control unit included in the communication control device further performs control to cause the information processing device to notify the information regarding the communication state acquired in the period and to determine a destination of a delivery confirmation request on the basis of the information regarding the communication state. Thereby, a destination of a delivery confirmation request can be appropriately determined.

Claims

1. :

A communication control device, comprising a control unit for performing control to notify an information processing device of a period for the information processing device to acquire information regarding a communication state in the information processing device, to cause the information processing device to notify the information regarding the communication state acquired in the period, and to determine a destination of a delivery confirmation request on the basis of the information regarding the communication state.

2. :

The communication control device according to claim 1, wherein the control unit performs control to cause the information processing device to transmit the information regarding the communication state in a case where the information processing device determines that the information regarding the communication state acquired in the period satisfies a predetermined condition.

3. :

The communication control device according to claim 1,

wherein at least one piece of information regarding the communication state acquired in the period is a reception characteristic in the information processing device, and

the control unit causes the information processing device to determine whether the reception characteristic in the information processing device satisfies a predetermined condition and, in a case where the reception characteristic satisfies the predetermined condition, causes the information processing device to transmit the information regarding the communication state.

4. :

The communication control device according to claim 1,

wherein the control unit performs control to notify the information processing device of period information for specifying a start and an end of the period.

5. :

The communication control device according to claim 4, wherein the control unit notifies the information processing device, as the period information, of at least one of start time of the period and a sequence number for starting the period and at least one of a duration of the period and end time of the period.

6. :

The communication control device according to claim 1,

wherein the control unit performs control to notify the information processing device of notification period information for specifying a notification period during which the information processing device can notify the communication control device of the information regarding the communication state.

7. :

The communication control device according to claim 6,

wherein the control unit notifies the information processing device, as the notification period information, of start time of the notification period and at least one of a duration of the notification period and end time of the notification period.

8. :

The communication control device according to claim 1,

wherein the control unit performs control to allow information regarding a reception characteristic in the information processing device to be notified as the information regarding the communication state.

9. :

The communication control device according to claim 8,

wherein the information regarding the reception characteristic includes at least one of a throughput, a packet loss rate, the number of multicast packets successfully received by the information processing device and addressed to a multicast group to which the information processing device belongs, and a ratio of a sum of noise power and interference power relative to a desired signal power.

10. :

The communication control device according to claim 1, wherein the control unit performs control to notify the information processing device of an identifier of an index indicating a reception characteristic in the information processing device, the identifier being information for specifying the information regarding the communication state.

11. :

The communication control device according to claim 1, wherein the control unit performs control to include at least one of the information regarding the period, information for specifying the information regarding the communication state, and notification period information for specifying a notification period during which the communication control device can be notified in a Radio Measurement Request frame or a part of a concatenated frame in which a plurality of frames are concatenated to transmit the information to the information processing device.

12. :

An information processing device, comprising a control unit for performing control to transmit, to a communication control device, information regarding a communication state in the information processing device acquired in a period notified from the communication control device.

13. :

The information processing device according to claim 12, wherein the control unit transmits the information regarding the communication state to the communication control device in a case where the acquired information regarding the communication state satisfies a predetermined condition.

14. :

The information processing device according to claim 12, wherein the control unit includes information regarding a reception characteristic in the information processing device as the information regarding the communication state.

15. :

The information processing device according to claim 14, wherein the information regarding the reception characteristic is one of a value corresponding to an index indicating a reception characteristic in the information processing device and a value corresponding to an identifier of the index.

16. :

The information processing device according to claim 12, wherein the control unit performs control to include the information regarding the communication state in a Radio Measurement Report frame or a Block Ack frame to transmit the information to the communication control device.

17. :

An information processing method, comprising a control procedure of notifying an information processing device of a period for the information processing device to acquire information regarding a communication state in the information processing device, causing the information processing device to notify the information regarding the communication state acquired in the period, and determining a destination of a delivery confirmation request on the basis of the information regarding the communication state.
