Electronic device for performing handover in wireless network environment and method thereof

A method of an electronic device, the method comprising:

• establishing, by a first wireless communication circuitry, a video call with an external electronic device over a 4G network or a WiFi network
• identifying, by a processor, resolution of video call, as negotiated within a call establishment procedure for establishing the video call;
• setting, by the processor, a reference value for executing a first handover to a 5G network to be less than a default value, when the identified resolution is greater than or equal to a predetermined threshold resolution;
• and
• performing the first handover from the 4G network or the WiFi network to the 5G network, when intensity of a signal from the 5G network is greater than or equal to the set reference value.

An electronic device, comprising:

• a 5G communication circuitry configured to communicate over a 5G network;
• a 4G communication circuitry configured to communicate over a 4G network;
• a WiFi communication circuitry configured to communicate over a WiFi network;
• and
• at least one processor operatively connected with the 5G communication circuitry, the 4G communication circuitry, and the WiFi communication circuitry,
• wherein the at least one processor is configured to:
• register an IMS with the WiFi network via the WiFi communication circuitry;
• identify a priority connection mode for the IMS;
• perform a handover from the WiFi network to the 5G network or the 4G network based on a plurality of thresholds for performing a handover to the WiFi network, when the identified priority connection mode is a WiFi priority connection mode;
• and
• perform the handover from the WiFi network to the 5G network or the 4G network based on a 4G signal intensity and a 5G signal intensity obtained at a prespecified period, when the identified priority connection mode is a cellular priority connection mode.
