perform a back-up operation in response to the use event; and

restore a state of the electronic device based on data that is stored as a result of executing the back-up operation, wherein the state of the electronic device is restored in response to a signal that is received from the secondary electronic device or a release of the use event.

5. The electronic device of claim 2 , wherein the at least one processor is further configured to:

detect the user's change of state by using at least one sensor;

detect whether the user's change of state is included in a preset reference; and

transmit information corresponding to the user's change of state to the secondary electronic device, when the user's change of state is included in the preset reference.

6. The electronic device of claim 1 , wherein the incoming communication includes one of a telephone call or a message, and transmitting the indication of the incoming communication includes transferring the incoming communication to the secondary electronic device.

7. The electronic device of claim 1 , wherein the detecting of the change of state is performed in response to the electronic device being in a restricted-use mode.

8. The electronic device of claim 1 , wherein the detecting of the change of state is performed based on a distance between the electronic device and the secondary electronic device.

9. The electronic device of claim 1 , wherein the electronic device includes a wearable electronic device, and the at least one processor is further configured to receive data obtained by using one or more sensors in the secondary electronic device and detect whether the electronic device is currently being worn based on the data.

10. The electronic device of claim 1 , wherein the processor is configured to transmit data to the secondary electronic device by using a push-to-talk (PTT) function.

11. The electronic device of claim 10 , wherein the data is transmitted in real-time or in a predetermined time unit based on a state of a connection between the electronic device and the secondary electronic device.

12. The electronic device of claim 10 , wherein the at least one processor is configured to execute the PTT function in response to a signal that is received from the secondary electronic device.

13. A method comprising:

establishing a wireless connection between a first device and a second device;

detecting a change of state of the first device using one or more sensors in the first device;

transmitting from the first device to the second device a first information associated with the change of state of the first device;

receiving, by the first device, a second information associated with a control of the first device that is transmitted by the second device in response to transmitting the first information;

performing, by the first device, an operation based on the second information,

receiving an incoming communication;

detecting whether the first device and the second device are being used by different users; and

transmitting to the second device an indication of the incoming communication when the first device and the second device are being used by different users.

14. The method of claim 13 , wherein the change of state is detected based on at least one of an external event, a use event associated with the first device, or an event associated with a change of state of a user of the first device.

15. The method of claim 14 , further comprising transmitting, to the second device, information relating to a mode in which the first device is operated when the first device and the second device are used by different users.

16. The method of claim 14 , further comprising:

performing a back-up operation in response to the use event; and

restoring a state of the first device based on data that is stored as a result of executing the back-up operation, wherein the state of the first device is restored in response to a signal that is received from the second device or a release of the use event.

17. The method of claim 14 , further comprising:

detecting the user's change of state by using at least one sensor;

detecting whether the user's change of state is included in a preset reference; and

transmitting information corresponding to the user's change of state to the second device, when the user's change of state is included in the preset reference.

18. The method of claim 13 , wherein the incoming communication includes one of a telephone call or a message, and transmitting the indication of the incoming communication includes transferring the incoming communication to the second device.

19. The method of claim 13 , wherein the detecting is performed in response to the first device being in a restricted-use mode.

20. The method of claim 13 , wherein the detecting is performed based on a distance between the first device and the second device.

21. The method of claim 13 , wherein the first device includes a wearable first device, further comprising receiving data obtained by using one or more sensors in the second device and detect whether the first device is currently being worn based on the data.

22. The method of claim 13 , further comprising transmitting data to the second device by using a push-to-talk (PTT) function.

23. The method of claim 22 , wherein the data is transmitted in real-time or in a predetermined time unit based on a state of the connection between the first device and the second device.
