at least one processor,
wherein the at least one processor is configured to:
receive a radio resource control (RRC) reconfiguration message including at least one first condition related to a conditional handover from a serving cell,
determine to perform the conditional handover, based on the at least one first condition related to the conditional handover included in the RRC reconfiguration message,
determine whether at least one second condition for suspending the conditional handover is satisfied, the at least one second condition being set by the electronic device, and
suspend transmitting a random access preamble for the conditional handover, based on satisfaction of at least one of the at least one second condition,
wherein the at least one second condition includes identification that a voice call is being performed by the electronic device, and
