Abstract

A call service method and an apparatus are provided. The call service method of an electronic device includes detecting a communication state change with a counterpart electronic device, checking a reason for the communication state change, and performing at least one of displaying communication state information based on the reason for the communication state change and recovering a call connection.

Claims

1. A call service method of an electronic device, the method comprising:

detecting a communication state change with a counterpart electronic device;

checking a reason for the communication state change; and

performing at least one of displaying communication state information based on the reason for the communication state change and recovering a communication connection,

wherein checking the reason for the communication state change comprises determining whether a communication state is changed based on a predetermined input signal and communication error code information included in a communication signal.

2. The method of claim 1, wherein the predetermined input signal instructs to end the communication connection.

3. The method of claim 1, wherein checking the reason for the communication state change further comprises determining, when the predetermined input signal is not received, that the communication state is changed due to an external cause.

4. The method of claim 1, wherein detecting the communication state change comprises determining at least one of whether a strength of a communication signal of a base station is equal to or less than a predetermined threshold, whether the electronic device moves out of a cell coverage area of the base station, and whether communication service information of the counterpart electronic device is changed.

5. The method of claim 1, wherein recovering the communication connection comprises requesting, when the communication connection drops due to an external cause, reestablishment of the communication connection with the counterpart electronic device.

6. The method of claim 5, wherein recovering the communication connection further comprises requesting reestablishment of the communication connection through a network different from a network on which the communication connection has dropped.

7. The method of claim 1, further comprising:

analyzing, when video data is not received from the counterpart electronic device or a strength of a communication signal carrying the video data is equal to or less than a predetermined threshold, voice data and expression data;

determining an emotion factor of a counterpart user based on the analyzed voice and expression data; and

displaying a still image of the counterpart user, which is modified according to the emotion factor of the counterpart user.

8. The method of claim 7, wherein the still image of the counterpart user is one of an image stored in association with identity information of the counterpart electronic device and an image received from the counterpart electronic device in the communication connection.

9. The method of claim 1, wherein displaying the communication state information comprises displaying, when the communication connection drops due to an external cause, a call connection screen during a predetermined period or displaying a call connection reestablishment request item.

10. An electronic device comprising:

a communication unit configured to transmit and receive communication signals;

a display unit configured to display communication service information; and

a processor configured to detect a communication state change with a counterpart electronic device, check a reason for the communication state change, control the display unit to display communication state information on a screen based on the reason for the communication state change, and recover a communication connection,

wherein the processor is further configured to determine whether a communication state is changed based on a predetermined input signal and communication error code information included in a communication signal.

11. The electronic device of claim 10, wherein the processor is further configured to determine, when the predetermined input signal is not received, that the communication state is changed due to an external cause.

12. The electronic device of claim 10, wherein the processor is further configured to request, when the communication connection drops due to an external cause, reestablishment of the communication connection with the counterpart electronic device.

13. The electronic device of claim 10, wherein the processor is further configured to control the display unit to display, when the communication connection drops due to an external cause, a communication connection screen during a predetermined period or to display a communication connection reestablishment request item.

14. The electronic device of claim 10, wherein the processor is further configured to control outputting the communication state information with at least one of a sound effect, an illumination effect, and a vibration effect.

15. The electronic device of claim 10, further comprising:

an emotion analysis module configured to analyze voice data and expression data to determine an emotion of a counterpart user; and

an image processing module configured to modify a still image of the counterpart user according to an emotion factor of the counterpart user,

wherein the processor is further configured to control, when video data is not received from the counterpart electronic device and a strength of a signal carrying the video data is equal to or less than a threshold, the display unit to display the still image of the counterpart user, the still image being modified based on the voice and expression data.

16. The electronic device of claim 15, wherein the still image of the counterpart user is one of an image stored in association with identity information of the counterpart electronic device and an image received from the counterpart electronic device in the communication connection.

17. The electronic device of claim 10, further comprising a short range communication module,

wherein the processor is further configured to control the communication unit to receive a streaming content from a server, control the short range communication module to transmit the streaming content to the counterpart electronic device, and control, when the communication state change is detected, the communication unit to transmit at least part of the streaming content to the counterpart electronic device.

18. The electronic device of claim 17, wherein the processor is further configured to request, when the communication connection drops due to an external cause, the server providing the streaming content and the counterpart electronic device for a streaming connection and control, when a signal of permitting the streaming connection from the counterpart electronic device is received, the communication unit to transmit server access account information and the at least part of the streaming content in response to the permission signal.
