Abstract: According to various embodiments, an electronic device may comprise: a memory, at least one antenna module comprising at least one antenna, and at least one communication processor. The at least one communication processor may be configured to: control the electronic device to perform a call by voice communication connection through a second communication network, in response to receiving a first call request, based on identifying that the call is disconnected, identify 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, start a timer for deferring connection to a first communication network, and in response to receiving a second call request before the timer expires, control the electronic device to perform a voice communication connection through the second communication network currently connected the electronic device.

Abstract: According to various embodiments, an electronic device comprises at least one processor. The at least one processor may be configured to: receive, from a network, a radio resource control (RRC) reconfiguration message including information about at least one bandwidth part (BWP) available to the electronic device, perform communication with the network using a first BWP among the at least one BWP, control the electronic device to transmit, to the network, a message requesting to change a BWP being used by the electronic device, based on identifying an event set for a change in BWP, receive, from the network, a downlink control indicator (DCI) indicating a change from the first BWP to a second BWP included in the at least one BWP, and perform communication with the network using the second BWP, based on the reception of the DCI.

Abstract: This disclosure relates to a 5G or pre-5G communication system supporting a higher data rate than a 4G communication system such as LIE. More specifically, a method for performing, by a terminal, communication in a wireless communication system of the present invention comprises: a step of performing a connection procedure for a first wireless network; a step of performing a connection procedure for a second wireless network; and a step of performing communication for the same service through the first wireless network or the second wireless network according to wireless link states of the first wireless network and the second wireless network.
