Abstract

Various embodiments of the present disclosure relate to a device and method for reducing current consumption in an electronic device. The electronic device may include a communication interface that transmits and receives a signal; and a processor that configures a multi-hop network with at least one other electronic device, and changes the transmission period of a message for a path management of the multi-hop network based on whether the multi-hop network configuration has been changed. Other embodiments are also possible.

Claims

1. An electronic device comprising:

a communication interface; and

a processor configured to configure a multi-hop network with at least one other electronic device, and changes a transmission period of a control message for a path management of the multi-hop network based on whether the multi-hop network configuration has been changed.

2. The electronic device of claim 1, wherein the processor is configured to identify whether the multi-hop network configuration has been changed by using a control message received from the at least one other electronic device, for the path management.

3. The electronic device of claim 1, wherein the processor is configured to reduce the transmission period of the control message when the multi-hop network configuration has been changed;

and

wherein the processor is configured to increase the transmission period of the message when the multi-hop network configuration has been maintained.

4. The electronic device of claim 1, wherein the processor is configured to change the transmission period of the control message to a minimum value in response to change of the multi-hop network configuration.

5. The electronic device of claim 1, wherein the processor is configured to determine an antenna mode with respect to a plurality of antennas functionally connected to the communication interface based on whether the multi-hop network configuration has been changed.

6. The electronic device of claim 5, wherein the processor is configured to set the antenna mode to a multi-antenna mode when the configuration of the multi-hop network has been changed;

and

the processor is configured to set the antenna mode to a single antenna mode when the configuration of the multi-hop network has been maintained,

wherein the multi-antenna mode indicates a antenna mode for transmitting and receiving signals using the plurality of antennas, and

the single antenna mode indicates a antenna mode for transmitting and receiving signals using any one antenna among the plurality of antennas.

7. The electronic device of claim 1, wherein the processor is configured to:

identify an amounts of data transmission and reception; and

change the transmission period of the control message based on the amounts of data transmission and reception and whether the multi-hop network configuration has been changed,

wherein the amounts of data transmission and reception may include at least one among an amounts of a data transmission or an amounts of a data reception.

8. The electronic device of claim 7, wherein the processor is configured to reduce the transmission period of the control message, when at least one among the amounts of data transmission or the amounts of data reception exceeds a reference value or the configuration of the multi-hop network has been changed;

and

the processor is configured to increase the transmission period of the control message, when the amounts of data transmission and the amounts of data reception are less than the reference value, and the configuration of the multi-hop network has been maintained.

9. The electronic device of claim 7, wherein the processor is configured to determine antenna mode with respect to a plurality of antennas functionally connected to the communication interface based on the amounts of data transmission and reception and whether the configuration of the multi-hop network has been changed.

10. The electronic device of claim 9, wherein the processor is configured to set the antenna mode to a multi-antenna mode when at least one among the amounts of data transmission or the amounts of data reception exceeds a reference value or the configuration of the multi-hop network has been changed;

and

the processor is configured to set the antenna mode to a single antenna mode when the amounts of data transmitted and the amounts of data received are less than the reference value and the configuration of a multi-hop network has been maintained.

11. A method for operating an electronic device, comprising:

configuring a multi-hop network with at least one other electronic device;

identifying whether the multi-hop network configuration has been changed; and

changing a transmission period of a control message for a path management of the multi-hop network based on whether the multi-hop network configuration has been changed.

12. The method of claim 11, wherein the identifying whether the multi-hop network configuration has been changed comprises:

identifying the multi-hop network configuration has been changed based on a control message received from the at least one other electronic device, for the path management.

13. The method of claim 11, wherein the changing the transmission period of the control message comprises:

reducing the transmission period of the control message when the multi-hop network configuration has been changed; and

increasing the transmission period of the control message when the multi-hop network configuration has been maintained.

14. The method of claim 11, wherein the changing the transmission period of the control message comprises:

changing the transmission period of the control messages to a minimum value, in response to a change to the configuration of the multi-hop network.

15. The method of claim 11, further comprising:

determining antenna mode with respect to a plurality of antennas functionally connected to the electronic device based on whether the multi-hop network configuration has been changed.
