based on the type of the call request being a first type, control the communication circuitry to transmit, to at least one external device among one or more external devices connected to the electronic device, a notification indicating that a call session is started,

based on the type of the call request being a second type, identify whether a recipient who is a user of the electronic device is in a call with another caller by allowing the at least one instruction to be executed,

identify a first external device close to the electronic device among the one or more external devices connected to the electronic device in case that it is identified that the recipient is in the call with the other caller, and

control the communication circuitry to transmit identification information for the identified first external device and a response to the call request to the server to transmit the call request to the identified first external device.

2 . The electronic device of claim 1 , wherein the at least one instruction, when executed by the one or more processors individually or collectively, further cause the electronic device to identify the first external device close to the electronic device among the one or more external devices based on information on a strength of a signal received from the one or more external devices through the communication circuitry.

3 . The electronic device of claim 1 ,

wherein the call request is a call request for performing a call based on mission critical push to talk (MCPTT) technology, and

wherein the first external device is a device capable of processing the call request based on the MCPTT technology.

4 . The electronic device of claim 3 , wherein the at least one instruction, when executed by the one or more processors individually or collectively, further cause the electronic device to:

allow a session initiation protocol (SIP) invitation based on the MCPTT call request to be received from the server through the communication circuitry, and

identify whether the recipient is in the call with the other caller based on whether a call session is established between the electronic device and another electronic device of the other caller.

5 . The electronic device of claim 1 , wherein the at least one instruction, when executed by the one or more processors individually or collectively, further cause the electronic device to:

identify a local network to which the electronic device is connected based on a position of the recipient, and

identify one or more external devices connected to the identified local network as the one or more external devices.

6 . The electronic device of claim 5 , wherein the position of the recipient is identified based on at least one of:

information on a position of the user received through a position information sensor included in the electronic device,

information on a strength of a signal received from the first external device through the communication circuitry, or

pre-stored network position information for the local network.

7 . The electronic device of claim 1 ,

wherein the at least one instruction, when executed by the one or more processors individually or collectively, further cause the electronic device to control the communication circuitry to transmit the notification and a request for broadcasting the notification to a second external device among the one or more external devices, and

wherein the second external device transmits a control signal corresponding to the notification to all the external devices other than the second external device among the one or more external devices based on the request.

8 . The electronic device of claim 7 , wherein the notification is transmitted to the one or more external devices at a predetermined period.

9 . The electronic device of claim 7 , wherein the one or more external devices change an on/off state, blink, output a voice, change color of information displayed, provide a notification through a display, or provide haptic vibration in response to the control signal.

10 . The electronic device of claim 7 , wherein the second external device is a hub device.

11 . The electronic device of claim 1 , wherein the server redirects the call request of the caller to the first external device based on the identification information for the first external device.

12 . The electronic device of claim 1 , wherein the identification information is subscriber identity module (SIM) information for the first external device.

13 . A controlling method of an electronic device, the method comprising:

receiving a call request of a caller from a server;

identifying a type of the call request;

based on the type of the call request being a first type, transmitting, to at least one external device among one or more external devices connected to the electronic device, a notification indicating that a call session is started;

based on the type of the call request being a second type, identifying whether a recipient who is a user of the electronic device is in a call with another caller;

identifying a first external device close to the electronic device among one or more external devices connected to the electronic device in case that it is identified that the recipient is in the call with the other caller; and

transmitting identification information for the identified first external device and a response to the call request to the server to transmit the call request to the identified first external device.

14 . The method of claim 13 , wherein the identifying of the first external device includes identifying the first external device close to the electronic device among the one or more external devices based on information on a strength of a signal received from the one or more external devices through communication circuitry.

15 . The method of claim 13 ,

wherein the call request is a call request for performing a call based on mission critical push to talk (MCPTT) technology, and

wherein the first external device is a device capable of processing the call request based on the MCPTT technology.

16 . The method of claim 13 , further comprising:

starting a call session according to the call request in case that the call request is a call request for performing a call based on emergency mission critical push to talk (MCPTT) technology; and

transmitting a notification indicating that the call session is started to one or more external devices among the identified one or more external devices in case that the response of the recipient to the call request is not received for a predetermined threshold time.

17 . The method of claim 16 , further comprising:

identifying a local network to which the electronic device is connected based on a position of the recipient; and

identifying one or more external devices connected to the identified local network as the one or more external devices.

18 . The method of claim 17 , wherein the position of the recipient is identified based on at least one of:

information on a position of the user received through a position information sensor included in the electronic device,

information on a strength of a signal received from the first external device, or

pre-stored network position information for the local network.

19 . The method of claim 16 , further comprising transmitting the notification and a request for broadcasting the notification to a second external device among the one or more external devices,

wherein the second external device transmits a control signal corresponding to the notification to all the external devices other than the second external device among the one or more external devices based on the request.

20 . The electronic device of claim 1 , wherein upon identifying the first external device, request the identification information from the first external device.
