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.

Abstract: An electronic device is disclosed. The electronic device includes a wireless communication circuitry, a processor operatively connected with the wireless communication circuitry, and a memory, operatively connected with the processor, storing configured network slice selection assistance information (NSSAI) and an application. The memory stores instructions, when executed, causing the processor to, when the electronic device is booted, identify a single-NSSAI (s-NSSAI) candidate group including at least one s-NSSAI, based on configuration information of the application, determine a specified number of s-NSSAIs among at least one s-NSSAI included in the configured NSSAI as a first requested NSSAI based on the number of s-NSSAIs included in the configured NSSAI and the s-NSSAI candidate group, and transmit a first registration request message including the first requested NSSAI, via the wireless communication circuitry.

Abstract: A terminal synchronization method and apparatus for use in a wireless communication system are provided. A synchronization method includes configuring, at the terminal, a synchronization signal reference time depending on whether a synchronization signal is received in an initial observation period as long as at least two frames, monitoring to receive the synchronization signal in an alternation period of a transmission period and a reception period, the alternation period following the initial observation period, updating the reference time depending on whether the synchronization signal is received in the reception period, transmitting the synchronization signal at the updated reference time in the transmission period, and updating the reference time depending on whether the synchronization signal is received in a dedicated observation period following the alternation period. The synchronization apparatus and method are advantageous in that synchronization is obtained without assistance of a base station, an Access Point (AP), etc.

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.
