Electronic device and call processing method thereof
An electronic device and method thereof are provided. The electronic device includes a communication module configured to communicate with a communication server; an input module configured to receive a user command; and a processor configured to receive a device changing command, via the input module, during a call between the electronic device and a first external electronic device, and transmit, to the communication server, via the communication module, a message for changing the call between the electronic device and the first external electronic device to a call between a second external electronic device and the first external electronic device. The second external electronic device uses a same subscription information as the electronic device, and the message includes call state information of the call between the electronic device and the first external electronic device.
1. An electronic device, comprising:
a display;
a transceiver; and
a processor configured to:
control the transceiver to receive, from a communication server, a first message including a first subscription information and call state information, wherein the call state information indicates a state of a call between a first external electronic device and a second external electronic device, and wherein the second external electronic device uses a same subscription information as the electronic device;
control the transceiver to receive, from the communication server, a second message inviting a call based on a request of the first external electronic device, wherein the second message comprises a second subscription information;
compare the second subscription information with the first subscription information;
based on that the second subscription information is equal to the first subscription information, establish the call between the electronic device and the first external electronic device; and
display, on the display, a user interface indicating a state of a call between the electronic device and the first external electronic device using the call state information.
2. The electronic device of claim 1 , wherein the processor is further configured to display, on the display, a user interface for receiving a call accepting command, based on that the second subscription information is different from the first subscription information.
3. The electronic device of claim 1 , wherein the processor is further configured to
compare the first subscription information or a first device identification information included in the first message with the second subscription information or a second device identification information included in the second message, based on that the received first message indicates that a call transfer of the call between the first external electronic device and the second external electronic device is scheduled, and
establish the call between the electronic device and the first external electronic device, based on that the first subscription information or the first device identification information is the same as the second subscription information or the second device identification information.
4. A method of an electronic device, the method comprising:
receiving, from a communication server, a first message including a first subscription information and call state information, wherein the call state information indicates a state of a call between a first external electronic device and a second external electronic device, and wherein the second external electronic device uses a same subscription information as the electronic device;
receiving, from the communication server, a second message inviting a call based on a request of the first external electronic device, wherein the second message comprises a second subscription information;
comparing the second subscription information with the first subscription information; and
based on that the second subscription information is equal to the first subscription information, changing the call between the first external electronic device and the second external electronic device to a call between the electronic device and the first external electronic device; and
displaying, on a display, a user interface indicating a state of the call between the electronic device and the first external electronic device using the call state information.
5. The method of claim 4 , further comprising displaying a user interface for receiving a call accepting command, based on that the second subscription information is different from the first subscription information.
