1. An electronic device comprising:
a first communication circuitry configured to provide first wireless communication using a first frequency range;
a second communication circuitry configured to provide second wireless communication using a second frequency range;
a processor operatively connected with the first communication circuitry and the second communication circuitry; and
a memory operatively connected with the processor,
wherein the memory stores instructions, when executed, causing the processor to:
establish a communication channel with a first base station, using the first communication circuitry;
receive a first message including at least one frequency information to measure a communication state using the second communication circuitry, from the first base station;
measure a communication state with at least one second base station, using the second communication circuitry based on the first message;
transmit a second message about the at least one second base station to the first base station, based on the measured result;
receive a third message including information about a selected second base station and timer information, based on the second message from the first base station;
start to run a timer based on the timer information and measure a channel state with the selected second base station, based on a signal received from the selected second base station, using the second communication circuitry; and
transmit a fourth message including the information of the selected second base station to the first base station, before the timer expires, based on the measured result,
wherein the timer includes time information where the electronic device is able to attempt to perform a communication connection with the selected second base station.
