Abstract: 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.
