Abstract: An electronic device is provided. The electronic device includes a first wireless communication circuit that provides a first radio access technology (RAT) associated with a long term evolution (LTE), a second wireless communication circuit that provides a second RAT associated with a new radio (NR), a subscriber identification module, a communication processor, and a memory. The electronic device obtains access technology identifier (ATI) information associated with one public land mobile network (PLMN) from the subscriber identification module and performs frequency scanning by using the first wireless communication circuit, when the ATI information indicates a next generation radio access network (NG-RAN) associated with the first RAT.

Abstract: 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.
