11. A method for processing a call request by an electronic device, the method comprising:
in response to receiving a first call request, performing a call by voice communication connection through a second communication network;
based on identifying that the call is disconnected, identifying information related to a call disconnected cause;
based on identifying that the identified information related to the call disconnected cause corresponds to a designated condition, starting a timer for deferring connection to a first communication network;
based on identifying that a second call request is received before the timer expires, performing voice communication connection through the currently connected second communication network; and
based on identifying that a message indicating redirection and/or handover from the second communication network to the first communication network is received before the timer expires, returning to the first communication network.
