Abstract

Claims (42)

1. An electronic device comprising:

a communication circuit configured to transmit or receive data over at least one link that is set up between an external electronic device and the electronic device; and

a processor configured to:

identify time intervals between packets that are transmitted or received over the at least one link;

identify a ratio of time intervals that are equal to or less than a designated value among the time intervals, wherein the ratio is a ratio of a length of time intervals that are equal to or less than the designated value to a length of time intervals that is equal to or greater than the designated value;

select a target wake time (TWT) mode or a power saving mode based on the ratio, wherein in the TWT mode the communication circuit is switched to an active state every designated time, and wherein in the power saving mode the communication circuit is switched to an inactive state in case that the packet is not transmitted or received during a designated time; and

control the communication circuit based on the selected mode.

2. The electronic device of claim 1 , wherein the processor is configured to select the TWT mode when the ratio is equal to or greater than a designated magnitude.

3. The electronic device of claim 1 , wherein the processor is configured to select the power saving mode when the ratio is equal to or less than a designated magnitude.

4. The electronic device of claim 1 , wherein the ratio is a ratio of a number of time intervals that are equal to or less than the designated value to a number of time intervals that are equal to or greater than the designated value.

5. The electronic device of claim 1 , wherein the designated value is equal to the designated time of the power saving mode.

6. The electronic device of claim 1 , wherein the processor is configured to determine whether to perform an operation of identifying time intervals between packets transmitted or received over the at least one link based on a type of service running on the electronic device.

7. The electronic device of claim 1 , wherein while the processor is transmitting or receiving packets with the external electronic device over a plurality of links, the processor is configured to:

identify time intervals between the packets that are transmitted or received over at least part links of the plurality of links;

identify a ratio of a length of time intervals among the time intervals that are equal to or less than the designated value to a length of time intervals among the time intervals that are equal to or greater than the designated value;

select the TWT mode or the power saving mode based on the ratio; and

control the communication circuit to allow the at least part links to operate in the selected mode.

8. The processor of claim 7 , wherein the processor is configured to select the TWT mode when the ratio is equal to or greater than a designated magnitude, and transmit a negotiation message of the TWT mode to the external electronic device, and

wherein the negotiation message of the TWT mode includes information indicating the at least part links.

9. The electronic device of claim 7 , wherein the processor is configured to select the power saving mode when the ratio is equal to or less than a designated magnitude.

10. The method of operating an electronic device, the method comprising:

identifying time intervals between packets that are transmitted or received over at least one link that is set up between an external electronic device and the electronic device;

identifying a ratio of time intervals that are equal to or less than a designated value among the time intervals, wherein the ratio is a ratio of a length of time intervals that are equal to or less than the designated value to a length of time intervals that are equal to or greater than the designated value;

selecting a target wake time (TWT) mode or a power saving mode based on the ratio, wherein in the TWT mode a communication circuit of the electronic device is switched to an active state every designated time, and wherein in the power saving mode the communication circuit is switched to an inactive state in case that no transmission or reception of the packets occurs during a designated time; and

controlling the communication circuit based on the selected mode.

11. The method of claim 10 , wherein the selecting comprises selecting the TWT mode when the ratio is equal to or greater than a designated magnitude.

12. The method of claim 10 , wherein the selecting comprises selecting the power saving mode when the ratio is equal to or less than a designated magnitude.

13. The method of claim 10 , wherein the ratio is a ratio of a number of time intervals that are equal to or less than the designated value to a number of time intervals that are equal to or greater than the designated value.

14. The method of claim 10 , wherein the designated value is equal to the designated time of the power saving mode.

15. The method of claim 10 , further comprising:

determining whether to perform an operation of identifying time intervals between packets transmitted or received over the at least one link based on a type of service running on the electronic device.

16. The method of claim 10 , wherein packets are transmitted or received to or from the external electronic device over a plurality of links, further comprising:

identifying time intervals between the packets that are transmitted or received over at least part links of the plurality of links;

identifying a ratio of a length of time intervals among the time intervals that are equal to or less than the designated value to a length of time intervals among the time intervals that are equal to or greater than the designated value;

selecting the TWT mode or the power saving mode based on the ratio; and

controlling the communication circuit to allow the at least part links to operate in the selected mode.

17. The method of claim 16 , further comprising:

selecting the TWT mode when the ratio is equal to or greater than a designated magnitude; and

transmitting a negotiation message of the TWT mode to the external electronic device,

wherein the negotiation message of the TWT mode includes information indicating the at least part links.

18. The method of claim 16 , further comprising:

selecting the power saving mode when the ratio is equal to or less than a designated magnitude.
