Abstract

Provided are an electronic device and method for avoiding interference between frequencies therefor. The electronic device may include: a housing; a wireless communication circuit arranged in the housing; at least one electronic component arranged in the housing; a processor electrically connected with the wireless communication circuit and the at least one electronic component; and a memory electrically connected with the processor. The memory may store instructions that, when executed, cause the processor to send or receive a signal to or from the at least one electronic component using a first frequency, to send or receive a signal to or from an external device through the wireless communication circuit using a second frequency, and to determine whether to change the first frequency in consideration of the second frequency. Other embodiments are possible.

First claim

What is claimed is:

1. An electronic device comprising:
a housing;
a wireless communication circuit arranged in the housing;
at least one electronic component arranged in the housing;
a processor electrically connected with the wireless communication circuit and the at least one electronic component; and
a memory electrically connected with the processor,
wherein the memory stores instructions that, when executed, cause the processor to detect occurrence of an interrupt, to search for a base station in response to detecting of the interrupt, to receive information on an idle channel from the base station, to connect to the idle channel on the basis of the received information, to send or receive a signal to or from the at least one electronic component using a first frequency, and to determine whether to change the first frequency in consideration of a second frequency associated with the connected channel.

2. The electronic device of claim 1 , wherein the instructions cause the processor to determine whether the first frequency and the second frequency interfere with each other, to change the first frequency to a third frequency, when the first frequency and the second frequency interfere with each other, and to maintain the first frequency, when the first frequency and the second frequency do not interfere with each other.

3. The electronic device of claim 1 , wherein the memory stores data associating the first frequency and the second frequency, and wherein the instructions cause the processor to determine whether to change the first frequency based on the stored data.

4. The electronic device of claim 1 , further comprising an embedded SIM (eSIM) card electrically connected with the wireless communication circuit, wherein the instructions cause the processor to determine the second frequency based on the eSIM card and to determine whether to change the first frequency by comparing the first frequency with the second frequency.

5. A method for operating an electronic device, comprising:
performing communication between electronic components of the electronic device using a first frequency;
detecting occurrence of an interrupt;
searching for a base station in response to detecting of the interrupt;
receiving information on an idle channel from the base station;
connecting to the idle channel on the basis of the received information;
identifying a second frequency associated with the connected channel;
determining whether the first frequency interferes with the second frequency; and
changing, upon determining that the first frequency interferes with the second frequency, the first frequency to a third frequency.

6. The method of claim 5 , wherein determining whether the first frequency interferes with the second frequency comprises examining data describing an interference relationship between the first frequency and the second frequency.

7. The method of claim 5 , wherein determining whether the first frequency interferes with the second frequency comprises determining that the first frequency interferes with the second frequency when an absolute value of the signal sensitivity associated with the second frequency is less than or equal to a first threshold.

8. The method of claim 5 , wherein changing the first frequency comprises changing, after determining that the first frequency interferes with the second frequency, the first frequency to the third frequency when the electronic device enters sleep mode.

9. The method of claim 5 , wherein changing the first frequency comprises changing, after determining that the first frequency interferes with the second frequency, the first frequency to the third frequency when a specific application terminates on the electronic device.

10. The method of claim 5 , further comprising:
determining whether the electronic device is placed in a strong electric field area; and
maintaining, when the electronic device is placed in a strong electric field area, the first frequency although the first frequency interferes with the second frequency,
wherein determining whether the electronic device is placed in a strong electric field area comprises determining that the electronic device is placed in a strong electric field area when an absolute value of the signal sensitivity associated with the second frequency is greater than or equal to a threshold.

11. An electronic device comprising:
a housing;
a wireless communication circuit arranged in the housing;
at least one electronic component arranged in the housing;
a processor electrically connected with the wireless communication circuit and the at least one electronic component; and
a memory electrically connected with the processor,
wherein the memory stores instructions that, when executed, cause the processor to communicate with the at least one electronic component using a first frequency, to detect occurrence of an interrupt, to search for a base station in response to detecting of the interrupt, to receive information on an idle channel from the base station, to connect to the idle channel on the basis of the received information, to identify a second frequency associated with the connected channel, to determine whether the first frequency and the second frequency interfere with each other, and to change the first frequency to a third frequency when the first frequency and the second frequency interfere with each other.

12. The electronic device of claim 11 , wherein the second frequency is used to send or receive a signal to or from an external device.

13. The electronic device of claim 11 , wherein the instructions cause the processor to identify the second frequency based on information received from a base station.

14. The electronic device of claim 11 , wherein the interrupt corresponds to at least one of booting of the electronic device, handover, SIM card insertion, roaming, opening, configuration change, GNSS activation, and WLAN activation.

15. The electronic device of claim 11 , wherein the memory stores data of a relationship of interference between the first frequency and the second frequency.

16. The electronic device of claim 11 , wherein the instructions cause the processor to determine that the first frequency and the second frequency interfere with each other when an absolute value of the signal sensitivity associated with the second frequency is less than or equal to a threshold.

17. The electronic device of claim 11 , wherein the instructions cause the processor to determine that the first frequency and the second frequency interfere with each other, and to change the first frequency to the third frequency when the electronic device is in sleep mode or a specific application terminates execution on the electronic device.

18. The electronic device of claim 11 , wherein the instructions cause the processor to determine whether the electronic device is placed in a strong electric field area, and to maintain, upon determining that the electronic device is placed in a strong electric field area, the first frequency although the first frequency and the second frequency have been determined to interfere with each other.

19. The electronic device of claim 18 , wherein the instructions cause the processor to determine that the electronic device is placed in a strong electric field area when an absolute value of the signal sensitivity associated with the second frequency is greater than or equal to a threshold.
