Abstract: According to an embodiment, an electronic device may comprise at least one communication processor. The at least one communication processor may be configured to: establish, based on dual connectivity, a first connection based on a first radio access technology (RAT) and a second connection based on a second RAT; transmit first uplink data based on the first connection and transmit second uplink data based on the second connection, wherein a throughput corresponding to the second connection may be a first value; identify at least one first parameter associated with the first connection and at least one second parameter associated with the second connection; perform at least one operation for transmitting, based on the second connection, uplink (UL) data with a throughput less than the first value, based on the at least one first parameter satisfying a first condition indicating a good uplink channel state and that the at least one second parameter satisfying a second condition indicating a poor uplink channel state; and based on performing the at least one operation, transmit third uplink data based on the first connection and transmit fourth uplink data based on the second connection, wherein a throughput corresponding to the second connection may be less than the first value.

Abstract: In an electronic device and an electronic device operating method, according to various embodiments, the electronic device comprises: a communication circuit for supporting first cellular communication and/or second cellular communication; an application processor; and a communication processor, wherein the application processor can be configured to: check whether the electronic device satisfies conditions related to the disconnection of the first cellular communication in a state in which the electronic device is connected through the first cellular communication; and transmit, on the basis of the electronic device satisfying the conditions related to the disconnection of the first cellular communication, to the communication processor, a signal indicating satisfaction of the conditions related to the disconnection of the first cellular communication, and the communication processor can be configured to: check, on the basis of the reception of the signal indicating satisfaction of the conditions related to the disconnection of the first cellular communication, whether system information including information, received from a node connected through the first cellular communication, about nodes adjacent to the node is received and/or whether a measure object satisfies designated conditions; disconnect the first cellular communication on the basis of whether the system information is received and/or whether the measure object satisfies the designated conditions; and connect the second cellular communication on the basis of the system information and/or the measure object. Various other embodiments are possible.
