Abstract: The disclosure relates to an apparatus and method for providing a call function in an electronic device. The electronic device includes first communication circuitry supporting new radio (NR) communication and/or long term evolution (LTE) communication, second communication circuitry supporting wireless local area network (LAN) communication, and at least one processor operatively connected to the first communication circuitry and the second communication circuitry. The processor may be configured to resister the electronic device with a network using the NR communication through the first communication circuitry, connect communication with an evolved packet data gateway (ePDG) based on a protocol data unit (PDU) session being identified as being connected over a network using wireless LAN communication in a state in which the electronic device has registered with the network using the NR communication, obtain information related to a call function of the network using the NR communication based on the communication connection with the ePDG, connect the PDU session over the network using the wireless LAN communication, and control the connection with the network using the NR communication based on the information related to the call function of the network using the NR communication.
