摘要： According to certain embodiments, an electronic device comprises at least one processor; and a memory operatively connected with the at least one processor and storing a plurality of identifiers related to attributes of a communication bearer. The memory stores instructions that, when executed by the at least one processor, cause the electronic device to: receive information related to multi radio access technology (RAT) dual connectivity (MR-DC) from a first base station (BS) connected with a first core network, using a first frequency band; transmit a first packet data network (PDN) connectivity request comprising a first identifier among the plurality of identifiers and a second PDN connectivity request comprising a second identifier among the plurality of identifiers to the first BS, using the first frequency band; establish a first PDN session with the first BS and the first core network, in which the first PDN session provides a communication bearer having a first attribute related to the first identifier; establish a second PDN session with the first BS and the first core network, in which the second PDN session provides a communication bearer having a second attribute related to the second identifier; receive from the first BS, a message indicating that the first BS is connected with a second BS; and communicate using signals with the second BS and the first core network through the second PDN session based on at least a part of the message, using the second frequency band.
