Electronic device, and method for processing ims-based call in electronic device

An electronic device comprising:

• at least one antenna module;
• at least one short-range communication module;
• at least one processor connected to the antenna module and the at least one short-range communication module;
• and
• a memory connected to the at least one processor,
• wherein the memory is configured to store instructions which, when executed, cause the processor to:
• register the electronic device to an IP multimedia subsystem (IMS) server through the at least one antenna module,
• identify a short-range communication method capable of a device to device (D2D) connection with at least one first external electronic device,
• connect, based on identification information of the at least one first external electronic device, with the at least one first external electronic device through the at least one short-range communication module with the identified short-range communication method, and
• process an IMS registration for the at least one first external electronic device in response to an IMS registration request received from the at least one first external electronic device through the at least one short-range communication module.
