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;

configures a multi-hop network with at least one other electronic device,

reduce a transmission period of a control message for a path management of the multi-hop network and set an antenna mode with respect to a plurality of antenna functionally connected to the communication interface to a multi-antenna mode based on determination that the multi-hop network configuration is changed, and

increase the transmission period of the control message and set the antenna mode to a single-antenna mode based on determination that the multi-hop network configuration is maintained,

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

wherein the single-antenna mode indicates an antenna mode for transmitting and receiving signals using any one antenna among the plurality of antenna.

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

4. The electronic device of claim 1, wherein the processor is further 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 is 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.

5. The electronic device of claim 4, wherein the processor is further configured to reduce the transmission period of the control message, based on determination that the amounts of data transmission and/or reception exceeds a reference value or the configuration of the multi-hop network is changed;

and

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

6. The electronic device of claim 4, wherein the processor is further configured to determine the antenna mode based on the amounts of data transmission and reception and whether the configuration of the multi-hop network is changed.

7. The electronic device of claim 6, wherein the processor is further configured to set the antenna mode to the multi-antenna mode based on determination that the amounts of data transmission and/or reception exceeds a reference value or the configuration of the multi-hop network is changed;

and

the processor is configured to set the antenna mode to the single antenna mode based on determination that the amounts of data transmitted and received are less than the reference value and the configuration of the multi-hop network is maintained.

8. 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 is changed;

reducing a transmission period of a control message for a path management of the multi-hop network and setting an antenna mode with respect to a plurality of antenna functionally connected to a communication interface to a multi-antenna mode based on determination that the multi-hop network configuration is changed; and

increasing the transmission period of the control message and setting the antenna mode to a single-antenna mode based on determination that the multi-hop network configuration is maintained,

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

wherein the single-antenna mode indicates an antenna mode for transmitting and receiving signals using any one antenna among the plurality of antenna.

9. The method of claim 8, wherein the identifying whether the multi-hop network configuration has been changed comprises:

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

10. The method of claim 8, 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.

11. The method of claim 8, wherein the changing of the transmission period of the control message comprises:

identifying an amounts of data transmitted and received to and from the electronic device;

changing of the transmission period of the control message based on the amounts of data transmitted and received and whether the multi-hop network configuration is changed.

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

reducing the transmission period of the control message, based on determination that the amounts of data transmitted and/or received exceeds a reference value or the configuration of the multi-hop network is changed; and

increasing the transmission period of the control message, based on determination that the amounts of data transmitted and received are less than the reference value and the configuration of the multi-hop network is maintained.

13. The method of claim 11, further comprising:

determining the antenna mode based on the amounts of data transmitted and received and whether the configuration of the multi-hop network is changed.

14. The method of claim 13, wherein the determining the antenna mode comprises:

setting the antenna mode to the multi-antenna mode based on determination that the amounts of data transmitted and/or received exceeds a reference value or the configuration of the multi-hop network is changed; and

setting the antenna mode to the single antenna mode based on determination that the amounts of data transmitted and received are less than the reference value and the configuration of the multi-hop network is maintained.
