Abstract

The present invention generally relates to a method for traffic control, and an electronic device therefor. An operation method of an electronic device may comprise the steps of: measuring the temperature of the electronic device through at least one sensor; checking an operation state of at least one application being executed in the electronic device; and controlling data throughput for each of the at least one application on the basis of the operation state of the at least one application if the measured temperature is equal to or greater than a reference value. Other various embodiments are possible.

First claim

The invention claimed is:

1. A method of operating an electronic device, the method comprising:
measuring a temperature of the electronic device through at least one sensor;
identifying an operation state of at least one application being executed in the electronic device, including whether the at least one application is operating in a foreground state or a background state;
detecting that the measured temperature is higher than or equal to a reference value; and
based on the detection and the operation state of the at least one application, controlling data throughput for the at least one application by:
determining a time period in which packets are generated,
detecting a total electrical current consumption over the time period,
detecting a portion of the time period in which the at least one application is radio active,
estimating an electrical current consumption of the at least one application by multiplying the total electrical current consumption by the portion of the time period, and
determining a future data throughput for the at least one application based on the estimated current consumption.

2. The method of claim 1 , wherein the operation state of the at least one application further includes at least one factor among a resource use rate of the at least one application, an accumulated amount of transmitted and received data, and a type of a Radio Access Technology (RAT) which the electronic device is accessing.

3. The method of claim 1 , wherein the controlling of the data throughput comprises:
determining a data throughput control level for the at least one application based on the operation state of the at least one application;
determining data throughput corresponding to the control level according to a data throughput policy; and
controlling transmission and reception traffic for the at least one application according to the determined data throughput.

4. The method of claim 3 , wherein the data throughput policy is information preset and stored in the electronic device or periodically updated from an external device.

5. The method of claim 4 , further comprising:
measuring a state of the electronic device; and
determining the data throughput policy based on the measured state of the electronic device.

6. The method of claim 5 , wherein the determining of the data throughput corresponding to the control level comprises determining the data throughput corresponding to the control level based on the determined data throughput policy.

7. The method of claim 5 , wherein the measured state of the electronic device includes at least one piece of information on a time point at which the electronic device is used and information on a location at which the electronic device is used.

8. The method of claim 1 , further comprising:
storing a data throughput control history for the at least one application; and
when the temperature of the electronic device is higher than or equal to the reference value, controlling data throughput for the applications, being executed, based on the stored data throughput control history.

9. The method of claim 1 , wherein the controlling of the data throughput for the at least one application comprises:
comparing the measured temperature with a reference value;
determining a heat level of the electronic device; and
when the heat level is higher than or equal to a preset reference, controlling data throughput for the at least one application based on the operation state of the at least one application.

10. An electronic device comprising:
at least one sensor used to measure temperature of the electronic device; and
at least one processor configured to:
identify an operation state of at least one application being executed in the electronic device, including whether the at least one application is operating in a foreground state or a background state,
detect that the measured temperature is higher than or equal to a reference value, and
based on the detection and the operation state of the at least one application, control data throughput for the at least one application by:
determining a time period in which packets are generated,
detecting a total electrical current consumption over the time period,
detecting a portion of the time period in which the at least one application is radio active,
estimating an electrical current consumption of the at least one application by multiplying the total electrical current consumption by the portion of the time period, and
determining a future data throughput for the at least one application based on the estimated current consumption.

11. The electronic device of claim 10 , wherein the operation state of the at least one application further includes at least one factor among a resource use rate of the at least one application, an accumulated amount of transmitted and received data, and a type of a Radio Access Technology (RAT) which the electronic device is accessing.

12. The electronic device of claim 10 , wherein the at least one processor determines a data throughput control level for the at least one application based on the operation state of the at least one application, determines data throughput corresponding to the control level according to a data throughput policy, and controls transmission and reception traffic for the at least one application according to the determined data throughput.

13. The electronic device of claim 10 , further comprising a memory configured to store a data throughput control history for the at least one application, wherein, when the temperature of the electronic device becomes the reference value or higher, the at least one processor controls data throughput for the applications, being executed, based on the stored data throughput control history.

14. The electronic device of claim 10 , wherein the at least one processor compares the measured temperature with a reference value, determines a heat level of the electronic device, and controls data throughput for the at least one application based on the operation state of the at least one application when the heat level is higher than or equal to a preset reference.
