1. An electronic device comprising:
a communication circuit;
a memory configured to store mapping data in which identification information of a cellular communication network and information indicating whether the cellular communication network supports a standalone (SA) mode of a first cellular communication supported thereby are mapped; and
a communication processor,
wherein the communication processor is configured to:
while the electronic device is set to connect the first cellular communication with priority over a second cellular communication and is in a coverage of a cellular communication network not supporting the SA mode of the first cellular communication, search for a node through the first cellular communication,
while searching for the node through the first cellular communication, receive system information broadcast by the node,
determine, based on identification information of a cellular communication network included in the received system information and the mapping data, whether the cellular communication network corresponding to the node supports the SA mode of the first cellular communication,
in response to determining that the cellular communication network does not support the SA mode of the first cellular communication based on the identification information of the cellular communication network and the mapping data, stop searching for the node through the first cellular communication before the searching for the node through the first cellular communication is complete, and
search for the node through the second cellular communication.
