1. A method of operating an electronic device, comprising:
receiving system information from a cell of a first radio access technology (RAT);
identifying whether the system information includes information for a cell of a second RAT different from the first RAT;
in case that the system information includes the information for the cell of the second RAT,
generating a first message including capability information of the electronic device for the second RAT;
supplying power to a transceiver related to the second RAT;
in case that the system information does not include the information for the cell of the second RAT,
generating a second message not including the capability information of the electronic device for the second RAT;
cutting off the power to the transceiver related to the second RAT;
transmitting the first message or the second message to the cell of the first RAT,
wherein the capability information of the electronic device for the second RAT included in the first message includes a parameter for evolved universal terrestrial radio access (EUTRA) new radio dual connectivity (EN-DC) capability, a parameter for multi-RAT dual connectivity (MR-DC) capability, and information for a security capability of the electronic device for the second RAT,
wherein both the first message and the second message include information indicating whether the electronic device supports EN-DC regardless of whether the system information includes the information for the cell of the second RAT.
