Method for controlling bitrate in realtime and electronic device thereof

A method for changing a bitrate during a voice call of an electronic device, the method comprising:

• making a packet based call to an external electronic device;
• obtaining communication environment information of the electronic device;
• determining a change in a bitrate of the packet based call based on the obtained communication environment information;
• identifying whether a voice is received in response to the determination of the change in the bitrate;
• and
• changing 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 being identified.

An electronic device comprising:

• a sound receiving circuit;
• a communication circuit;
• a processor operatively connected to the sound receiving circuit and the communication circuit;
• and
• a memory operatively connected to the processor,
• wherein, the electronic device is configured to make a packet based call with an external electronic device using the communication circuit, and the memory stores one or more instructions that, when executed, cause the processor to control the electronic device to:
• encode a sound signal received using the sound receiving circuit using a codec at a first bitrate to transmit the encoded sound signal to the external electronic device at a first period;
• obtain communication environment information of the electronic device using the communication circuit;
• determine a change in a bitrate of the packet based call based on the obtained communication environment information;
• identify at least one silent section among a plurality of sound signal sections received through the sound receiving circuit and divided into units of the first period in response to the determination of the change in the bitrate;
• and
• change the bitrate of the packet based call from the first bitrate to a second bitrate in the identified at least one silent section.
