    摘要： An electronic device includes a communication processor; a processor connected to the communication processor; and a memory connected to the processor and the communication processor. The memory stores a domain name system (DNS) table, first instructions that, when executed, cause the processor to: generate a first DNS query message including a domain address based on execution of a networking service; and deliver the first DNS query message to the communication processor, and second instructions that, when executed, cause the communication processor to update the DNS table by periodically receiving a first DNS response message including an IP address corresponding to the domain address, as a response to the first DNS query message, delivering the first DNS response message to the processor; transmitting a second DNS query message including the domain address to the network, and receiving a second DNS response message, as a response to the second DNS query message.

    摘要： An electronic device is provided. The electronic device includes a first processor configured to perform wireless communication with a local area data network (LADN), and a second processor electrically connected with the first processor. The first processor is configured to receive a first message from the LADN indicating that a wireless communication session with the LADN is deactivated because the electronic device has departed from a geographic service area of the LADN, after receiving the first message, and transmit a second message to the second processor indicating that the wireless communication session is deactivated. The second processor is configured to terminate generation of a data packet for uplink transmission after receiving the second message.

    摘要： Disclosed according to various embodiments is an electronic device comprising: a first communication circuit configured to provide first wireless communication within a first frequency range; a second communication circuit configured to provide second wireless communication within a second frequency range; a processor operably connected to the first communication circuit and the second communication circuit; and a memory operably connected to the processor, wherein the memory has instructions stored therein which cause, when executed, the processor to: establish a channel for communication with a first base station, by using the first communication circuit; receive, from the first base station, a first message containing information about at least one frequency at which to assess a communication status by using the second communication circuit; assess statuses for communication with one or more second base stations, by using the second communication circuit on the basis of the first message; transmit a second message concerning the one or more second base stations to the first base station on the basis of results obtained by the assessment; receive, from the first base station, a third message containing information about a selected second base station and timer information on the basis of the second message; start a timer on the basis of the timer information and then, by using the second communication circuit, assess a status for communication with the selected second base station on the basis of a signal received from the selected second base station; and transmit a fourth message containing information about the selected second base station to the first base station before the end of the timer on the basis of results obtained by the assessment. Various other embodiments found through the specification are also possible.
