Abstract: According to various embodiments, an electronic device may comprise: a memory, at least one antenna module comprising at least one antenna, and at least one communication processor. The at least one communication processor may be configured to: control the electronic device to perform a call by voice communication connection through a second communication network, in response to receiving a first call request, based on identifying that the call is disconnected, identify information related to a call disconnected cause, based on identifying that the identified information related to the call disconnected cause corresponds to a designated condition, start a timer for deferring connection to a first communication network, and in response to receiving a second call request before the timer expires, control the electronic device to perform a voice communication connection through the second communication network currently connected the electronic device.

Abstract: One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed one or more processors of an electronic device individually or collectively, cause the electronic device to perform at least one operation are provided. The at least one operation include performing, by the electronic device, a first scan for a first part of a plurality of frequencies for non-terrestrial networks (NTN) communication by using a first radio frequency (RF) path of the electronic device corresponding to a first subscriber identity module (SIM) capable of being used by the one or more processors, while the first scan is being performed, performing, by the electronic device, a second scan for a second part of the plurality of frequencies for the NTN communication by using a second RF path of the electronic device corresponding to a second SIM capable of being used by the one or more processors, the second part at least including frequencies different from the first part, and performing, by the electronic device using the first SIM, at least one operation for accessing a cell identified by the second scan.

Abstract: Disclosed is an electronic device including a sound receiving circuit, a communication circuit, a processor, and a memory. The memory may store one or more instructions that, when executed, cause the processor to control the electronic device to: make a packet based call with an external electronic device using the communication circuit, to obtain communication environment information of the electronic device, to determine a change in a bitrate of the packet based call based on the obtained communication environment information, to identify whether a voice is received through the sound receiving circuit, and to change the bitrate of the packet based call from a first bitrate to a second bitrate based on a silent section in which the voice is not received through the sound receiving circuit being identified.
